The current origin is Gitea and +server-side Actions is externally disabled; committing these controls does not enable or prove +remote execution. An administrator must enable Actions, provide compatible runners, configure +required checks, and require code-owner review separately. + +External actions execute only by verified full commit SHA; inline comments retain the immutable +release tag for review. GitHub dependency review publishes check output but never writes a PR +summary comment, preserving the workflow-wide `contents: read` permission. + +GitHub dependency review and dependency submission depend on GitHub.com APIs. They are guarded by +`github.server_url == 'https://github.com'` and intentionally skip on Gitea. `trivy-fs` is the +platform-neutral release-blocking snapshot and runs for pull requests, `main` pushes, daily +schedule, and manual dispatch. + +The later supply-chain slice owns image builds/scans, SBOM, signing, provenance, tag release, and +retention. This policy does not claim those absent jobs. + +## Severity and response + +| Severity | CI posture | Target remediation | +| --- | --- | --- | +| KEV / Critical | block | 7 days or the CISA due date, whichever is sooner | +| High | block | 30 days | +| Medium | advisory | 90 days | +| Low | advisory | best effort | + +High/Critical is the template's release threshold. The exact threshold and remediation targets are +team policy rather than an external mandate and should be reviewed when the template is adopted. +GitHub dependency review applies the same High threshold to newly introduced runtime dependencies. + +The Trivy JSON snapshot is also compared with the CISA Known Exploited Vulnerabilities catalog. +Any intersection blocks regardless of Trivy severity. Before intersection, CI requires nonblank +catalog metadata, a positive integral declared count, a non-empty vulnerability array whose length +matches that count, and unique CVE-pattern `cveID` values. A missing, empty, malformed, +count-inconsistent, duplicate, or unreachable KEV feed fails closed; configure the `KEV_FEED_URL` +repository variable to an approved internal mirror when direct CISA access is unavailable. + +Candidate extraction also validates Trivy's JSON first: the top level must be an object with a +non-empty `Results` array; each result is an object whose `Vulnerabilities` value is null or an +array; and every listed vulnerability has a nonblank string `VulnerabilityID`. Invalid scanner +output fails closed instead of becoming an empty candidate set. + +## Scanner and network requirements + +Trivy scans the committed filesystem and Gradle lockfiles. High/Critical findings exit non-zero; +Medium/Low findings are reported with exit zero. Scanner database or tool-download failures remain +failures rather than silently producing an empty result. + +Runners need HTTPS egress to: + +- the configured Trivy binary source (GitHub Releases by default); +- Trivy vulnerability databases (the scanner defaults, commonly OCI registries); +- jq releases, unless `JQ_DOWNLOAD_BASE_URL` points to an internal mirror; +- the CISA KEV feed, unless `KEV_FEED_URL` points to an internal mirror; +- GitHub action sources when the forge does not mirror actions. + +Closed networks must mirror the pinned Trivy/jq artifacts and checksums, set +`TRIVY_DOWNLOAD_BASE_URL` and `JQ_DOWNLOAD_BASE_URL`, configure Trivy's documented database mirror +environment, and set `KEV_FEED_URL`. Mirror availability and freshness are operational +dependencies; stale mirrors can delay detection. + +## Suppression governance + +The only suppression source is repository-root `.trivyignore.yaml`. Every Trivy scan passes it +explicitly with `--ignorefile .trivyignore.yaml`. Each future entry must contain an identifier, a +non-empty rationale, and a future expiry no more than 90 days away. `verifyTrivyignore` validates +the shape and expiry; CODEOWNERS plus branch protection controls who may approve the change. +Neither control substitutes for the other. + +Do not use an ad-hoc ignore file or an inline scanner bypass. An expired suppression is removed or +renewed with fresh owner review and current evidence. + +## Dependency update policy + +Renovate is the checked-in security-update bot configuration. Patch/pin/digest security updates +may auto-merge only after every configured required check succeeds; minor and major updates require +human review. Dependency declarations and all 19 `gradle.lockfile` files must move together, and +`verifyDependencyLocks` remains release-blocking. + +Bot alerts are not a transitive-dependency backstop on every forge. Use a Gradle constraint or +resolution rule for a vulnerable transitive dependency, refresh locks deliberately, and retain the +full-snapshot Trivy scan. diff --git a/.github/pull_request_template.md b/.github/pull_request_template.md new file mode 100644 index 0000000..d46f76e --- /dev/null +++ b/.github/pull_request_template.md @@ -0,0 +1,18 @@ +## What changed and why + + + +## Verification + +- [ ] I ran the focused test for each changed leaf. +- [ ] I ran `cd src && ./gradlew check verifyPublicPathSnapshot verifyDependencyLocks`. +- [ ] I did not add an unregistered production module dependency. +- [ ] Dependency changes include refreshed `gradle.lockfile` files and a strict-lock verification. +- [ ] Trivy suppressions include an owner-reviewed reason and an expiry within 90 days. +- [ ] Any quarantined test is registered in `flaky-quarantine.yaml` with a reason, issue, and + `quarantined_since` date. +- [ ] I documented checks that could not run and their remaining risk. + +## Compatibility and operations + + diff --git a/.github/scripts/install-jq.sh b/.github/scripts/install-jq.sh new file mode 100644 index 0000000..92f0f62 --- /dev/null +++ b/.github/scripts/install-jq.sh @@ -0,0 +1,50 @@ +#!/usr/bin/env bash +set -euo pipefail + +readonly JQ_VERSION='1.8.1' +readonly JQ_SHA256_AMD64='020468de7539ce70ef1bceaf7cde2e8c4f2ca6c3afb84642aabc5c97d9fc2a0d' +readonly JQ_SHA256_ARM64='6bc62f25981328edd3cfcfe6fe51b073f2d7e7710d7ef7fcdac28d4e384fc3d4' +readonly DOWNLOAD_BASE_URL="${JQ_DOWNLOAD_BASE_URL:-https://github.com/jqlang/jq/releases/download/jq-${JQ_VERSION}}" + +: "${RUNNER_TEMP:?RUNNER_TEMP must be set by the CI runner}" +: "${GITHUB_PATH:?GITHUB_PATH must be set by the CI runner}" + +architecture="${RUNNER_ARCH:-$(uname -m)}" +case "${architecture}" in + X64 | x86_64 | amd64) + asset='jq-linux-amd64' + expected_sha256="${JQ_SHA256_AMD64}" + ;; + ARM64 | aarch64 | arm64) + asset='jq-linux-arm64' + expected_sha256="${JQ_SHA256_ARM64}" + ;; + *) + printf '::error::install-jq: unsupported runner architecture: %s\n' "${architecture}" >&2 + exit 1 + ;; +esac + +install_dir="${RUNNER_TEMP}/jq-${JQ_VERSION}/bin" +destination="${install_dir}/jq" +mkdir -p "${install_dir}" + +temporary="$(mktemp "${RUNNER_TEMP}/jq-${JQ_VERSION}.XXXXXX")" +trap 'rm -f "${temporary}"' EXIT + +curl --fail --show-error --silent --location --retry 3 \ + --proto '=https' --tlsv1.2 \ + "${DOWNLOAD_BASE_URL}/${asset}" \ + --output "${temporary}" +printf '%s %s\n' "${expected_sha256}" "${temporary}" | sha256sum -c - +chmod 0755 "${temporary}" +mv "${temporary}" "${destination}" +trap - EXIT + +printf '%s\n' "${install_dir}" >> "${GITHUB_PATH}" +installed_version="$("${destination}" --version)" +if [[ "${installed_version}" != "jq-${JQ_VERSION}" ]]; then + printf '::error::install-jq: expected jq-%s, got %s\n' "${JQ_VERSION}" "${installed_version}" >&2 + exit 1 +fi +printf 'install-jq: %s installed under RUNNER_TEMP\n' "${installed_version}" diff --git a/.github/scripts/verify-gate-matrix.sh b/.github/scripts/verify-gate-matrix.sh new file mode 100644 index 0000000..aa488dd --- /dev/null +++ b/.github/scripts/verify-gate-matrix.sh @@ -0,0 +1,365 @@ +#!/usr/bin/env bash +set -euo pipefail + +readonly SCRIPT_DIR="$(cd -- "$(dirname -- "${BASH_SOURCE[0]}")" && pwd -P)" +if (( $# > 1 )); then + printf '::error::gate-matrix-lint: expected zero arguments or one repository root\n' >&2 + exit 2 +fi + +if (( $# == 1 )); then + if [[ !

Quota settlement is FIFO within a scope + +Nothing links a reservation row to the upload that took it, and the design deliberately reclaims +stragglers by TTL and the `STALE_QUOTA_RESERVATION` cleanup type rather than threading a reservation +id through the upload session. `QuotaCommitGateway` therefore settles the oldest live reservation in +the file's namespace. + +Which row closes does not change any quota decision: enforcement sums reserved and committed bytes +per scope and never reads an individual row. Concurrent uploads of different sizes can leave the +reserved total transiently high or low, and it converges as each settles. Durable usage with no live +reservation behind it — an upload that outlived its TTL — is still recorded, because a ledger that +silently under-counts is worse than one that is briefly imprecise. + +Pinned by `PostgreSqlFileserverReclamationIntegrationTest`. + +### 10. Zero copy is a channel transfer, not a file handoff + +Task 22 asks for zero copy on local files; §19 forbids a `Path` leaving the storage adapter, and §5 +of the plan forbids adding `Path` to the content store. WebFlux's zero-copy API takes a `Path`, so +that route is closed. + +The servlet path takes the other one: `ZeroCopyDownloadGateway` receives a `WritableByteChannel` from +the transport and the storage adapter performs `FileChannel.transferTo` into it. That is a genuine +kernel-level transfer with no filesystem concept leaving storage. The reactive path continues to +stream with bounded demand. + +Zero copy is an optimization with no observable difference: when storage declines, the response is +streamed and is byte-identical. + +Pinned by `LocalStorageGatewayContractTest` and `ZeroCopyEligibilityTest`. + +### 11. The Fileserver JPA stores are gated on the capability switch + +The metadata store, session store, quota service, queues, ledger, and staging locator carry +`@ConditionalOnProperty(app.fileserver-platform.enabled)` even though the rest of +`adapter:outbound:persistence-jpa` is unconditional. + +Without the gate, every composition root that includes the persistence module built these beans — +including `sample-portfolio`, which has no Fileserver — and each of them needs collaborators only +the Fileserver configuration provides. That is the same rule the design states for the transport +surface, applied to persistence: no surface appears merely because the dependency is present. + +`FileStateMachine` is bound alongside them, in `FileserverStorageConfiguration`. It had no +production binding at all before, which made the metadata store unconstructible in any +component-scanned context. + +Pinned by `SampleApplicationContextTest` (the capability off) and +`FileserverRuntimeAssemblyTest` (the capability on). + +### 12. Transaction boundaries are owned by the application services, and are deliberately narrow + +The design does not say where a transaction begins. The repository does: +`adapter:outbound:persistence-jpa` forbids a repository adapter from owning a `@Transactional` +boundary, and `application-core` owns them through `TransactionPort`. The Fileserver follows that +rule — every `Jpa*` store here declares no `@Transactional` of its own. + +What is specific to this capability is how narrow the boundaries are. A boundary covers a contiguous +run of metadata writes and **stops before every storage call**, because a filesystem operation +inside a database transaction would hold a connection for the length of a byte transfer. The upload +path therefore has three boundaries, not one: acquire the lease, transfer the bytes, commit the +offset. + +Where several stores must agree, they share one boundary: + +| Unit | Why it is one boundary | +| --- | --- | +| reserve quota + insert record + create session | a reservation that outlived a failed insert holds capacity for a file that never existed | +| READY transition + quota commit | a finished file whose reservation was never converted holds capacity until the reservation expires | +| `markDeleting` + enqueue cleanup | a file that stopped being reachable with nothing queued to reclaim it is never collected | +| content delete settlement: reclaim + retire record + close queue item | half of it leaves the item to be retried against content that no longer exists | + +What this cannot make atomic is the storage/metadata seam itself — no database boundary could. That +seam is exactly what the ambiguous-completion path and the reconciler exist for, and the one +hand-written compensation that remains (staging creation failing after the records committed) is +there for the same reason. + +Pinned by `FileserverRoundTripContractTest` against real PostgreSQL; the application tests use +`DirectTransactions`, which runs a boundary inline and counts it. + +## Not implemented + +### `AsyncContentStore`, `CapacityAwareContentStore`, `CopyCapableContentStore`, `DelegatedDownloadStore` + +Four optional content-store SPIs are declared in `application-core` with no implementation. Each is +an extension point for a backend this template does not ship: + +- `AsyncContentStore` — for a backend whose native client is non-blocking. The local platform is + blocking, and the reactive transport bridges to it on a dedicated I/O scheduler. +- `CapacityAwareContentStore` — capacity is reported through `StorageHealthPort` and + `StorageUsageProbe`, which the local platform implements. +- `CopyCapableContentStore` — server-side copy is delivered by `CopyContentGateway`; the local + platform has no cheaper primitive than a streamed copy. +- `DelegatedDownloadStore` — delegation is delivered at the transport boundary by the nginx + `X-Accel-Redirect` strategy, which needs no store participation. + +`ContentStoreCapabilities` reports what the running store actually supports, so no unimplemented SPI +is advertised as available. + +## Known deviation from the repository's application-layer contract + +### 5. Fileserver application services are not `CommandUseCase` / `QueryUseCase` + +`src/application-core/CLAUDE.md` requires every inbound port implementation to extend +`CommandUseCase` or `QueryUseCase` and to carry `@UseCaseCapability`, which declares its transaction +mode, idempotency and repository access. The Fileserver instead exposes multi-method services — +`UploadApplicationService`, `DownloadApplicationService`, `FileLifecycleService`, +`FileserverAdminService` and their `Default*` implementations. + +This is a real deviation, not an oversight, and it is unenforced: the ArchUnit rules +`inbound_port_implementations_end_with_use_case` and +`inbound_port_implementations_declare_capability` only match types that implement `UseCase`, so a +service that never does is silently exempt. The capability contract that every other feature in +this repository declares is therefore absent here. + +Two things follow from it. The transaction mode of each operation is expressed only by which +`TransactionPort` method the body happens to call, rather than declared and checked. And the +application layer holds transport policy it would not hold if each operation were a use case with +its own command: HTTP status codes on `FileserverErrorCode`, `Range` and conditional-request +parsing in `api.transfer`, and `Content-Disposition` construction. + +The status mapping in particular is a deliberate trade rather than an accident. It lives in +`application-core` so the servlet transport, the reactive transport and the Nginx delegation path +cannot answer the same failure with three different statuses. Moving it to the transport layer +resolves the layering complaint and reintroduces exactly that drift, which is why this is an +architecture decision rather than a cleanup. + +**Status: open, deliberately unresolved in this change set.** Closing it means roughly thirty +command/query use cases, a decision about where the shared status vocabulary lives, and a change to +the ArchUnit rules so a service that bypasses the contract fails the build instead of being exempt +from it. That belongs in its own ADR with its own review, and doing it inside a correctness patch +would mix a large mechanical refactor into changes that need to be readable. + +Nothing here is pinned by a test, because the deviation is the absence of a constraint. The next +step is the ADR, not another test. + diff --git a/docs/fileserver/http-contract.md b/docs/fileserver/http-contract.md new file mode 100644 index 0000000..44fed52 --- /dev/null +++ b/docs/fileserver/http-contract.md @@ -0,0 +1,105 @@ +# Fileserver HTTP contract + +Every public endpoint is listed here. `FileserverDocumentationCoverageTest` scans the controllers +and fails if one is missing, so this file cannot silently fall behind the code. + +## Public endpoints + +| Method | Path | Success | Notes | +|---|---|---|---| +| POST | `/v1/files` | `201` READY, `202` VERIFYING | multipart single upload | +| POST | `/v1/files:raw` | `201`, `202` | the whole request body is the file | +| POST | `/v1/files:batch` | `200` | ordered per-part results;

A + `WEB_CLIENT` profile with `redirect.enabled=true` did not follow redirects; the caller received the + 3xx as an ordinary response. Refused until the reactive coordinator exists. +- `RETRY_POLICY_CONTRADICTS_ATTEMPTS` — `retry.policy` was read by nothing on the execution path, so + the actuator could report `none` for a profile retrying three times. The two settings must now + agree: `policy: none` requires `max-attempts: 1`, and any other policy requires more than one. +- `FULL_URL_RECORDING_FORBIDDEN` / `BODY_LOGGING_FORBIDDEN` — both settings were bindable and inert. + Recording an expanded URL puts path identifiers and query strings into unbounded metric tags; + recording bodies puts someone else's data into logs.

Writing it found five defects that no amount of reading the files would have surfaced: + +1. A Redis ACL file accepts neither comments nor line continuations — the original files did not load + at all, and the server refused to start. +2. The advanced account granted `SMEMBERS` and `SORT`, both `RAW_ONLY` and therefore the raw gateway + account's alone. +3. The ordinary account granted `SORT_RO` for the same reason. +4. The ordinary account could not run `PUBLISH`, `SUBSCRIBE`, or `PING`, all classified `TYPED`. +5. The ordinary account could not run `MULTI`, `EXEC`, `UNWATCH`, or `DISCARD`, also `TYPED`. + +6. The admin account was missing twelve read-only diagnostics the catalog exposes — the `OBJECT`, + `PUBSUB`, `XINFO`, `FUNCTION LIST`/`STATS`, and `CLUSTER KEYSLOT` subcommands. + +7. The cursor-scan reply budget was sized to the requested `COUNT`, which Redis treats as a hint — + a real `HSCAN COUNT 500` came back with 501 entries and the SDK refused a correct reply. + +Points 2 and 3 are the ones that matter: the account is the last enforcement boundary, so an account +wider than the catalog silently removes the second control the design relies on. + +### What the standalone guardrail run established + +`LiveRedisGuardrailTest` wires the real guard, catalog, and typed operations to a live server — +the first time `LettuceRedisCommandGateway`, the one class that encodes commands, runs under the +SDK's own contracts rather than against the in-memory stand-in. It carries the plan's datasets: a +value at the 1 MiB ceiling, a hundred-thousand-field hash, hundred-thousand-member set and sorted +set, a twenty-thousand-element list, a stream trimmed to 1,000 while twenty thousand entries are +appended, and a five-hundred-command batch. + +The assertions are about limits holding, not throughput. A guardrail test that measured absolute +speed would fail on a loaded laptop and teach nobody anything. + +### What the Sentinel promotion run established + +`LiveRedisSentinelPromotionTest` forces one real promotion and asserts several independent claims +about it. Every write carries a token unique to the run, so the list on the promoted primary is a +verbatim record of what happened and each per-call verdict can be checked against it. + +It found the most serious defect in this delivery, and it is not in the SDK's code: + +> **A superseded primary keeps acknowledging writes.** Sentinel promoted the replica at +> `05:56:12.503` and did not demote the old primary until `05:56:23.529` — eleven seconds in which +> the client, still connected, wrote and was told `+OK` **2,086 times**. Every one of those writes +> was discarded when the old primary resynced from the new one. Exactly **one** command failed. No +> client-side signal exists for this: the server answered, so the driver, the SDK, and the caller +> all correctly recorded a success. + +`SentinelFailoverObserver` counts *ambiguous* writes, and its documentation used to call those "the +ones an operator has to reconcile". That was wrong by three orders of magnitude, and the class now +says so. + +What closes the window is on the server, not the client. Re-running the identical promotion with +`min-replicas-to-write 1` and `min-replicas-max-lag 1` configured cut acknowledged-and-discarded +writes from **2,086 to 1**: the orphaned primary refused 2,020 writes with `NOREPLICAS`, which the +SDK translates to a definite, non-ambiguous failure the caller can act on. Both settings are now in +the lane, and `acknowledgedWriteLossIsBounded` ties the tolerated loss to the configured lag window, +so removing them makes the count jump by an order of magnitude and fails the test. + +That assertion then caught a second version of the same mistake within a day of being written. The +first guarded run passed; the second failed with 2,099 lost writes, because the setting had been +written into the lane's `primary` service only. The two data nodes swap roles on every failover, so +a guardrail applied to whichever one happens to start as primary stops applying the moment the lane +does the thing it exists to do. Both nodes now take their whole configuration from one definition. +Three consecutive promotions in both directions since: 0, 0, and 1 acknowledged write lost. + +The run also found a translator defect. A promotion closed the channel under an in-flight `RPUSH` +and the driver raised a bare `RedisException`, which matched no branch and fell through to a generic +failure reported as *definitely did not run*. Nothing about an unrecognised failure supports that +claim, and a caller who believes it retries a non-idempotent write. The fallback now treats an +unclassified write failure as ambiguous. + +### What the Cluster run established + +`LiveRedisClusterTest` checks the part of `sdk.cluster` that is pure client-side arithmetic against +the server that has the last word. The calculator agreed with `CLUSTER KEYSLOT` on every entry of a +corpus built from the brace rules a hand-written implementation gets wrong — an empty tag `{}`, +`foo{}{bar}`, `foo{{bar}}zap`, an unclosed brace, `}{`, the empty key, and non-ASCII keys — and the +rendered-key invariant holds: the slot the SDK computes from a tag alone equals the slot the server +computes from the whole rendered key. + +Cross-slot refusal was checked in both directions, because a guard stricter than the cluster costs +availability for no reason and a looser one sends requests that cannot succeed. The same key pair +the guard refuses is the pair the server answers `CROSSSLOT` for. + +Redirects were observed rather than assumed: a `MOVED` names the slot the client computed, and a +slot put into a real `MIGRATING`/`IMPORTING` state answers `ASK` for an absent key and `TRYAGAIN` +for a multi-key request that straddles the migration. The lane restores the slot to `STABLE` +afterwards, so a run leaves the cluster as it found it. diff --git a/docs/redis/upgrade-guide.md b/docs/redis/upgrade-guide.md new file mode 100644 index 0000000..0b92940 --- /dev/null +++ b/docs/redis/upgrade-guide.md @@ -0,0 +1,62 @@ +# Redis and client upgrade gate + +Changing the Redis server version or the Lettuce version is not a dependency bump. Both change what +commands exist, what they reply, and what an ACL account is allowed to do — all three are things this +SDK encodes as fixed decisions. The checks below must pass before either version moves, and each one +exists because skipping it produces a specific failure that only shows up in production. + +## 1. Command metadata diff + +Run the catalog drift check against the new server. Every command the server reports must be +classified in `src/adapter/outbound/cache-redis/src/main/resources/redis-sdk/redis-command-policy.yml`. + +*Why:* an unclassified command is refused by `CommandPolicyGuard`, so a server that grew a command +does not create a hole — but a command whose **risk changed upstream** and is still classified R1 +here does. The diff is what surfaces that. + +## 2. ACL regression + +Re-run `ACL DRYRUN` for every account against every command the SDK can issue, using +`RedisAdminOperations.aclDryRun`. + +*Why:* a permit never widens an ACL account, so the account is the last boundary. A new server +version that moved a command into a different ACL category silently turns a working call into a +runtime refusal on the first request that needs it. + +## 3. Serializer golden bytes + +Compare the encoded form of every registered codec against the stored golden bytes. + +*Why:* a value written by the old version must still decode after the upgrade. A codec change that +looks harmless in a round-trip test is not harmless against data already in the instance. + +## 4. Support matrix + +Update `docs/redis/support-matrix.md`. `RedisSupportMatrixTest` fails when a module or capability is +missing, and the certified-version table must not claim a version until its topology lane has +actually run. + +## 5. Topology suite + +Run the standalone, Sentinel, and Cluster lanes declared in `infra/redis-sdk/`. A version is +certified by the lane passing, not by the version number being newer. + +*Why:* failover certainty and cross-slot behaviour are the two things the in-memory fixture cannot +prove. `ExecutionCertainty` and `RedisSlotCalculator` are classification and arithmetic; whether the +driver actually behaves that way during a promotion or a resharding is only observable on a real +topology. + +## 6. Rollback + +Before the upgrade, record the previous server version, the previous Lettuce version, and the +`SCRIPT LOAD` digests of every registered script. A rollback is not complete until the digests +resolve again on the restored version. + +*Why:* digests are cached per process and invalidated by `SCRIPT FLUSH` and by restarts. A rollback +that leaves a process holding digests the restored server does not know produces `NOSCRIPT` on +every scripted call until the cache is dropped. + +## What this gate does not cover + +Data migration.

`FinalizeOutboxAuthorityCutoverUseCase` to the atomic database + finalization contract. It accepts an opaque, human-approved cutover evidence ID and never + trusts command booleans for writer/relay/producer drain. Before reconciliation it must CAS the + exact fresh attempt `CUTOVER_PENDING -> FINALIZING_V2` in the same database transaction that + commits the epoch, after taking the global write-admission/ACTIVE-epoch locks in the fixed + order and proving it is the sole nonterminal `OUTBOX_PUBLICATION` attempt; + `RECOVERING_LEGACY`, an expired attempt or a different operation owner is a hard rejection. + Rollback restores `CUTOVER_PENDING`, while a successful epoch commit records `CONSUMED_V2`. + This is a one-shot maintenance use case, not a second web endpoint. +- [ ] `OutboxLegacyToV2CutoverCoordinator` is the deployment/composition owner. Through + `OutboxWriteAdmissionControlPort`, `LegacyOutboxRelayControlPort` and + `PublicationGenerationLifecyclePort`, it freezes writes, drains writers/relay/futures, + closes/fences legacy Write, compiles/attests the canonical tuple and asks + `OutboxCutoverPreconditionPort` to persist a short-lived one-shot evidence record containing + exact node/writer/relay/producer generations, zero-active facts, epoch, manifest digest, + approver and expiry in `CUTOVER_PENDING`. Evidence creation uses the global lock order + write-admission singleton `FOR UPDATE` then ACTIVE epoch `FOR UPDATE`, requires the exact + FROZEN generation/target binding and rejects any nonterminal attempt in + `OUTBOX_PUBLICATION`; the partial unique constraint is the final concurrent-insert guard. + Bootstrap imports only application ports; it never queries repositories or Kafka adapter + internals. +- [ ] Implement the production write fence with the PostgreSQL singleton created in Task 7. + `SpringTransactionPort.inWrite` begins its transaction, acquires `FOR KEY SHARE` through + `PostgreSqlOutboxWriteAdmissionGuard`, and verifies OPEN + expected fence generation before + invoking any business action. The control adapter takes `FOR UPDATE`, waits for all older + share-holding writers to commit/rollback, writes FROZEN generation and then returns a durable + zero-active snapshot. New `inWrite` calls fail and roll back; `inNew` remains available only + for maintenance/outbox/audit and never bypasses a business write. +- [ ] Implement both explicit generation-CAS exits from FROZEN without a raw status update. + `ResumePollingV2WriteAdmissionUseCase` requires expected frozen generation, exact ACTIVE + `POLLING_V2` epoch, canonical cutover sentinel created through `OutboxAppendAdapter` and + persisted as `DELIVERY_RECORDED`, fresh target binding/readiness and no legacy runtime. It + writes `OPEN(generation+1)` once; mismatch/replay/failure leaves FROZEN. + `RecoverLegacyOutboxAuthorityUseCase` is legal only before epoch commit. Before any external + ACL mutation, its prepare operation takes the same global write-admission/ACTIVE-epoch lock + order, proves the exact attempt is the sole nonterminal authority attempt plus + FROZEN/`LEGACY_POLLING`/zero-v2-authority, then CAS-claims + `CUTOVER_PENDING -> RECOVERING_LEGACY` and atomically invalidates that attempt for v2 + finalization. Choosing this branch is irreversible for that attempt; only recovery completion + or recovery-only lease takeover remains legal. The complete operation follows the separately + fenced recovery protocol below. +- [ ] Register bounded `outbox_runtime_node_lease` heartbeats for every runtime node with node ID, + source/artifact digest, write-fence protocol version, epoch and scheduler roles. Precondition + evidence requires all deployment-inventory instances to have a matching fresh lease and + rejects stale, unknown, pre-fence or missing nodes. A lease table alone does not prove the + absence of an unregistered process; target deployment inventory/provenance is also mandatory. +- [ ] `LegacyOutboxRelayControlAdapter` owns composition of existing runtime controls: + pause new `OutboxRelayScheduler` cycles, wait active cycles/claims to the finite deadline, + pause/drain the epoch-fenced `OutboxReaper`, and close + `LegacyPublicationWriteFence` so `OutboxMessagePublishAdapter` rejects every later send. + Snapshot counts/generations are bounded facts only. Reopen methods require expected component + generations plus fresh pre-commit recovery evidence and reject once ACTIVE epoch is not + `LEGACY_POLLING`; no generic boolean setter exists. Application cutover policy sees the port, + not concrete scheduler/reaper/messaging types. +- [ ] The disposable security rehearsal and actual target preflight use distinct legacy/canonical + principals. Revoke legacy exact-topic Write and require a negative Write probe while canonical + Describe/DescribeConfigs/Write stays positive. The in-process fence plus external ACL evidence + are both required; neither substitutes for the other. +- [ ] Add the exact non-web one-shot operational entrypoint + `MessagingAuthorityCutoverApplicationRunner`. It activates only for + the closed operations `legacy-to-polling-v2`, `recover-legacy-precommit`, or + `resume-polling-v2-writes`. It requires opaque operation/approval-evidence IDs plus expected + target/source/artifact/epoch/fence generation, invokes only the corresponding application use + case/coordinator, emits no payload/secret, and exits non-zero on mismatch/replay/failure. The + main cutover exits 0 only after sentinel/readiness proof and write admission + `OPEN(generation+1)`; a post-commit resume failure stays FROZEN and requires the separately + one-shot `resume-polling-v2-writes` operation. Consumed DB evidence/operation IDs make retries + non-reentrant; no controller endpoint is added. + + ```text + ca-skeleton.messaging.maintenance.operation + ca-skeleton.messaging.maintenance.operation-id + ca-skeleton.messaging.maintenance.approval-evidence-id + ca-skeleton.messaging.maintenance.expected-target-alias + ca-skeleton.messaging.maintenance.expected-source-digest + ca-skeleton.messaging.maintenance.expected-artifact-digest + ca-skeleton.messaging.maintenance.expected-epoch + ca-skeleton.messaging.maintenance.expected-fence-generation + ``` + + Task 23 registers these exact maintenance-only keys and the runbook's non-web launcher + contract; none has a default that enables the runner. +- [ ] In the rehearsal harness: + deploy ACK-aware producer/v2 relay scheduler-disabled; compile the candidate tuple; prove + disposition auth/CAS negatives; execute the real PostgreSQL business-write admission freeze; + drain active writers/epoch share holders; stop legacy new claims and legacy reaper; drain + `IN_FLIGHT` to the maximum budget; audit remaining indeterminate; close/fence legacy producer + Write and DB legacy mutation. +- [ ] Real multi-node PostgreSQL tests hold old `inWrite` transactions across freeze, start new + writers during/after freeze, inject a stale/pre-fence node lease and omit a deployment + inventory member. Freeze must wait for old holders, reject new writes without partial business/ + outbox state, and refuse evidence until every live instance/fence/relay/reaper/producer fact is + exact and zero-active. +- [ ] In one PostgreSQL transaction: + + ```text + lock OUTBOX_PUBLICATION write-admission singleton FOR UPDATE + -> lock ACTIVE LEGACY_POLLING epoch FOR UPDATE + -> assert exact FROZEN generation/target binding and sole nonterminal attempt + -> lock exact fresh cutover attempt + -> CAS CUTOVER_PENDING -> FINALIZING_V2 + -> assert writer/legacy mutation fences + -> capture fixed legacy handoff watermark + -> final reconcile every row through watermark including final delta + -> assert exactly one CURRENT delivery per event, active claims 0 + -> assert row count + event ID/hash manifest, unmapped/duplicate count 0 + -> switch ACTIVE epoch LEGACY_POLLING -> POLLING_V2 + -> append v2 cutover sentinel through the canonical append adapter + with retained V3 projection + CURRENT/READY delivery + -> mark the same attempt CONSUMED_V2 + -> commit + ``` + +- [ ] Missing, expired, reused, wrong-epoch/generation, wrong-manifest or non-zero cutover evidence + rolls back before reconciliation. `RECOVERING_LEGACY`, `RECOVERED_LEGACY`, a foreign recovery + owner or any non-`CUTOVER_PENDING` state also rejects finalization. The final transaction + marks the evidence consumed; the coordinator cannot replay it. +- [ ] Migration-only state mapping is exact: + + ```text + PENDING -> READY + FAILED -> RETRY_WAIT with reviewed DB-time due/budget + DEAD -> EXHAUSTED + PUBLISHED -> LEGACY_RECORDED_UNVERIFIED + IN_FLIGHT -> HOLD + remaining-indeterminate audit + ``` + + Preserve reviewed attempt count/due/deadline and every historical observation; never + fabricate broker metadata, definite rejection, ACK observed time or `DELIVERY_RECORDED`. +- [ ] Any unknown contract/status/hash mismatch, duplicate current row, count/manifest mismatch, + active claim, fence failure or sentinel failure rolls the whole transaction back and leaves + `LEGACY_POLLING` authoritative. +- [ ] In the disposable rehearsal only, after commit start v2 relay, require sentinel + ACK/`DELIVERY_RECORDED`, prove the sentinel used the canonical append path and retained V3 NOT + NULL projection, verify legacy writer/claim/reaper/send 0, then execute the exact + FROZEN→OPEN generation CAS.

It calls the coordinator and + `FinalizeOutboxAuthorityCutoverUseCase`; the single transaction repeats the Task 20 + `CUTOVER_PENDING -> FINALIZING_V2` CAS, + watermark/final-delta/manifest/current-delivery assertions, epoch switch, sentinel insert and + `CONSUMED_V2` transition. `RECOVERING_LEGACY` is rejected before reconciliation.

Either retry forward within + the still-fresh bounded evidence/approval window, or execute the approved abort-to-legacy + protocol. The latter first proves epoch still `LEGACY_POLLING`, v2 business send/sentinel + authority 0 and exact inventory, then runs the prepare half of + `recover-legacy-precommit`: DB-CAS the exact attempt + `CUTOVER_PENDING -> RECOVERING_LEGACY`, bind the recovery operation/lease/evidence digest and + atomically make every forward finalizer reject it. This choice is irreversible for that + attempt, including after lease expiry. The prepare transaction holds the global + write-admission/ACTIVE-epoch locks in order and proves the partial-unique-protected attempt is + the sole nonterminal `OUTBOX_PUBLICATION` attempt.

The completion half + re-locks the global authority, exact attempt and epoch after that external mutation; + owner/lease, uniqueness or `LEGACY_POLLING` mismatch immediately re-revokes legacy Write, + proves a fresh negative probe and leaves writes FROZEN. + On success it appends recovery/ACL audit, reopens the in-process legacy Write fence/reaper/ + relay, then CAS-opens durable writes and marks `RECOVERED_LEGACY` last. Emit: + + ```text + src/app-bootstrap/build/messaging-evidence/precommit-legacy-recovery/manifest.json + ci-artifact://messaging/{targetAlias}/{sourceDigest}/precommit-legacy-recovery/manifest.json + ``` + + Validate identical bytes against the common and deployment-rollout schemas with + `outcome=ABORTED_PRECOMMIT`, exact restored legacy/write-admission generations, recovery + scenario IDs exactly once, failed=0 and skipped=0. + Any partial failure leaves writes FROZEN and is retried/re-fenced; recovery lease takeover is + recovery-only and never restores forward-finalization eligibility. Race tests must run + recovery-prepare versus same- and different-attempt creation/finalization in both lock orders, + and crash tests must cover every boundary before/after claim, ACL regrant, epoch revalidation, + component reopen and final admission CAS. The protocol never uses raw SQL. An aborted attempt + ends Task 25 without cutover; another attempt is rejected until recovery atomically records + `RECOVERED_LEGACY` and opens a new fence generation, then requires fresh preflight, approval + and target attestation. +- [ ] After epoch commit, start only v2 relay while writes remain FROZEN. Require the canonical + sentinel `DELIVERY_RECORDED`, retained V3 projection, fresh target binding/readiness and legacy + writer/claim/reaper/send 0. Then `ResumePollingV2WriteAdmissionUseCase` CAS-opens + `OPEN(generation+1)`. If the original runner dies or resume fails after commit, + `resume-polling-v2-writes` is the only recovery operation; it rechecks the same facts and + cannot reactivate legacy. After OPEN, exercise an ordinary canonical append; failure freezes a + new generation and keeps the rollout non-healthy. +- [ ] Apply the rehearsed rollback zones exactly: + pre-commit failure retains legacy DB authority but stays in maintenance until bounded forward + retry or the full audited recovery above succeeds; after epoch commit, reverse epoch and legacy + reactivation are unsupported even before the first business v2 send. Keep admission FROZEN, + preserve backlog/schema/epoch/audit and forward-fix or run the guarded v2 resume. +- [ ] Abort and fence admission on any duplicate anomaly, unexpected indeterminate, backlog/SLO + breach, late-observation drop, stale legacy mutation, topic/security drift or readiness loss. + Never automatically resend while diagnosing. +- [ ] Emit a sanitized target rollout artifact: + + ```text + src/app-bootstrap/build/messaging-evidence/deployment-cutover/manifest.json + ci-artifact://messaging/{targetAlias}/{sourceDigest}/deployment-cutover/manifest.json + ``` + + It binds target environment/cluster alias, source/artifact/release manifest digest, + target-binding-attestation digest, precondition evidence digest, watermark/manifest counts, + epoch/sentinel facts, final OPEN fence generation, ordinary post-resume append probe, + commands/timestamps, rollback zone, failures/skips and operator approvals. Payload, event hash, + credential and raw IDs remain excluded. The target runner writes identical bytes to the local + handoff and retained CI URI; both validate against the common build-evidence schema and + `deployment-rollout-manifest-v1.schema.json`. +- [ ] After commit, sentinel proof and artifact handoff, run + `verifyMessagingTargetBinding verifyMessagingDeploymentCutover` GREEN. Expected: binding and + deployment schemas PASS, exact target/source/artifact/release/attestation digest match, + approval/epoch/sentinel scenario IDs present exactly once, failed=0 and skipped=0. +- [ ] Acceptance claim: the exact target uses `POLLING_V2` and the sentinel/reference path is + healthy, and durable write admission is OPEN at the recorded post-cutover generation.

The wrapper/ + client refuses network start after the committed absolute wire deadline and enforces the + smaller of its monotonic elapsed budget and DB interval; + `TerminalizeExpiredNotificationWriterPermitsUseCase` is a distinct PRE-only authenticated + root-write operation that, only during exact DRAINING, terminalizes bounded DB-time-expired + ACTIVE permits across all generations with registry-bound token/rowVersion CAS; + `SwitchNotificationWriterOwnershipUseCase` physically commits the + audited `BEGIN_DRAIN`, `COMPLETE_SWITCH` or `ABORT_DRAIN` CAS. `BEGIN_DRAIN` verifies an + independently signed, short-lived exact environment/DB/route/PRE-artifact complete + old-writer inventory through `NotificationWriterInventoryEvidenceVerifierPort`, then + atomically freezes its canonical node row set/count/digest while closing new legacy acquire; + caller-authored node digests have no authority. The operations query polls active count/max + expiry outside a transaction; + `COMPLETE_SWITCH` refuses unsafe legacy permits. Freeze the only transition matrix: + `ACTIVE/LEGACY@g -> DRAINING/LEGACY@g` (BEGIN), + unchanged DRAINING (terminalize), + `DRAINING/LEGACY@g -> ACTIVE/CANONICAL@g+1` (COMPLETE), or + `DRAINING/LEGACY@g -> ACTIVE/LEGACY@g+1` (ABORT). Requests never supply a target owner; + every action from CANONICAL and every reverse transition fails with mutation 0. Crashed permits become + `EXPIRED_PROVEN` only for a transport profile with tested hard bounds; current R0 timeouts + become `TIMED_OUT_UNPROVEN`. For an unproven profile, an authenticated, immutable, fresh + route/generation quiescence attestation is mandatory even when the unproven set is empty. + Its independently signed manifest must exactly match the complete BEGIN node inventory and bind + per-node retired/quiesced facts plus deployment-generation tombstones and legacy + credential/egress revocation that make resume impossible, production consumer inventory/count 0 and provider-call ledger + identity/open-count 0. ACTIVE permit 0 remains mandatory for every profile and cannot be + overridden by attestation. It includes the bounded canonical + digest of every generation/profile `TIMED_OUT_UNPROVEN` + `(token,generation,profile,state,rowVersion)` permit tuple, the distinct permit-holder set and + the persisted transport-proof registry; COMPLETE locks/recomputes the exact sets and records + its token/digest. Every permit holder must be in the BEGIN inventory. The route-level + proof requirement is `QUIESCENCE_REQUIRED` when any current/retiring persisted registry + profile is `QUIESCENCE_REQUIRED`; only an all-`HARD_BOUND_PROVEN` registry may use the + hard-bound path. Every switch + operation carries authenticated actor, reason and reviewed target + generation. For every COMPLETE arm, application validation alone is insufficient: the + persistence port must lock the retained BEGIN inventory header/children and pass its canonical + payload/signature/SPKI/trust snapshot back through the Java verifier before the ownership + mutation. It rejects a missing, altered, unverifiable or semantically mismatched BEGIN even + when the permit/registry rows are structurally valid. QUIESCENCE_REQUIRED additionally locks + and revalidates the committed signed quiescence header, exact per-node + tombstone/revocation rows, ACTIVE permit 0 and provider-ledger open-count 0. + HARD_BOUND_PROVEN forbids a quiescence header/children but still requires the verified signed + BEGIN plus the exact all-hard-bound registry/evidence revision, safe terminal permits and + ACTIVE permit 0. The ownership transaction returns only after physical commit. Manifest + expiry gates admission into an immutable evidence header; once verified and committed, the + signed deployment/credential/egress fences are durable monotonic facts and are not converted + into a pre-commit TTL guard. No use case sleeps or holds a DB transaction while waiting. + The route's exact transport profile/proof/evidence registry comes from + `NotificationWriterRouteSet`, not permit rows or request data; therefore a + `QUIESCENCE_REQUIRED` route with permit count 0 still requires attestation. +- [ ] Cover audited batch `InitializeNotificationWriterFencesUseCase`: it rejects ambient + transactions and root-commits the bounded ordered reviewed route set as + `ACTIVE/LEGACY@predecessor` only when the command set/digest exactly equals + `NotificationWriterRouteSet` derived from the compiled cutover route catalog and every + notification control/data-plane journal table is empty. It inserts all + fences, one immutable operation header, all route-result children and the exact route/profile/ + admission-role/proof-class/evidence-revision registry snapshot atomically; partial or + sequential route initialization is forbidden. Initialization and every later switch append + immutable operation history in the same root transaction as fence mutation. Replay of any old + same-token/same-input route set returns its stored committed result; token reuse with a + different route set/action/input and existing/mismatched/nonempty state fail without mutation. + A mutable `last_operation_token` fence field is never the audit or replay SSOT. +- [ ] Cover `TerminalizeExpiredNotificationWriterPermitsUseCase`: it is not a scheduler, snapshot + query or COMPLETE side effect. An authenticated PRE operator supplies exact route/drain + generation, bounded batch (`<=100`), reason and opaque operation token. The root transaction + locks `DRAINING/LEGACY`, the immutable persisted registry and DB-time-expired ACTIVE permits + across all historical generations in canonical order. It CASes exact token/rowVersion to + `EXPIRED_PROVEN` only for HARD_BOUND_PROVEN or `TIMED_OUT_UNPROVEN` only for + QUIESCENCE_REQUIRED, then appends affected count/set digest and actor/reason in the operation + journal before commit. Same-token/same-input replay returns the stored result; changed input, + non-DRAINING fence, unknown/drifted profile, nonexpired row or commit failure changes nothing. + Idempotency lookup precedes set selection, so replay still returns the original affected result + after those rows are terminal. The affected set is a derived result, not caller input, and its + digest covers the sorted immutable post-CAS tuple. The operation journal persists requested + batch bound and a server-canonical request-input digest so changed-input token reuse fails. It + performs provider I/O 0 and never updates the fence's latest-mutation pointer. +- [ ] Cover `RecordNotificationWriterQuiescenceAttestationUseCase`: only a method-security operator + path may root-commit an immutable exact route/draining-generation/transport-profile + set attestation after BEGIN_DRAIN. It accepts a bounded signed quiescence manifest, verifies it + through the trusted issuer-key port, and server-derives the bounded sorted blocking permit + `(token,generation,profile,state,rowVersion)` set/count/digest, distinct holder set, frozen BEGIN + old-node set, consumer inventory/count 0 and provider-call-ledger identity/open-count 0.

cases: + Model three disjoint states. `PURE_DISABLED` means canonical `disabled` plus legacy config absent + and has every notification runtime resource 0. `PRE_LEGACY_BRIDGE` means canonical `disabled` + plus exact legacy-only config in a structurally detected PRE artifact; canonical + provider/store/worker resources are 0 while the transitional operator/fence/permit and selected + legacy provider exist, with admission/call 0 before initialization. `CANONICAL_CONFIGURED` + requires exact binding-ID equality and no legacy key. Unknown/extra/missing + binding/property/provider/template/revision fails; expected-mode mismatch fails; exact send/store/ + ingress account-region-configuration-set-topic tuple plus retry/DLQ/max-callback-age/tombstone + profile; live/retained revision availability; + legacy+canonical conflict fails even when values agree. The bounded + `APP_NOTIFICATION_EXPECTED_WRITER_GENERATIONS` key set must equal the compiled route catalog; + each value is the reviewed canonical target and its legacy predecessor is `target - 1`. A dark + legacy bridge may start with no fences but admits 0 until batch initialization creates the + complete predecessor set. During route-by-route switching, an exact key set may legally mix + `ACTIVE/LEGACY@predecessor` (legacy admits), `DRAINING/LEGACY@predecessor` (neither admits) and + `ACTIVE/CANONICAL@target` (canonical admits); each node opens only its owner-matching route. + `REQUIRE_CANONICAL` final startup requires every route at the exact canonical target. + `CUTOVER_WAIT` is permitted only in a PRE artifact with canonical-only config and the same + closed predecessor/target state machine. Each predecessor route has admission, dispatcher + claim and provider call 0 and readiness reports bounded `CUTOVER_WAIT`; it activates only + after a committed fence read proves `ACTIVE/CANONICAL@target`. + Before initialization, absent fences plus an empty persisted proof registry remain dark. Once + any initialization row exists, the snapshot's route/profile/admission-role/proof-class/ + evidence-revision/digest set must exactly equal `NotificationCutoverRouteCatalog`; partial, + extra or drifted registry state closes readiness and every writer. + Absent/partial/extra set, unrelated generation/owner/state, mixed legacy+canonical config in + one process or caller override fails startup/activation. Runtime drift from the allowed + predecessor/target state closes that route and readiness before any new work. + `NotificationCompositionValidator` derives `CUTOVER_WAIT` only from the PRE structural stage, + canonical-only graph and persisted exact fence state; no request, environment key or generic + Spring property may select it. +- [ ] RED zero-resource cases: + PURE_DISABLED -> provider/store worker/client/executor/scheduler/probe/readiness + component/operator/application DML·table scan 0; no secret lookup, cert fetch or provider + health call. Run this assertion after release-owned Flyway migrations; V7/V8 DDL validation is + not feature-gated application activity. An exact-empty database remains + `AWAITING_SIGNED_FRESH_PROVISIONING`, with application admission, workers and provider clients + dark until the separate provisioning operation commits. + PRE_LEGACY_BRIDGE -> canonical resources 0, only exact transitional + legacy resources present, + provider call 0 before audited initialization, then every legacy call requires a committed + permit. CANONICAL_CONFIGURED -> legacy/transitional admission path closed as dictated by the + ownership state. `NotificationZeroResourceTest`, `NotificationCompositionTest` and + `FencedLegacyNotificationPortTest` each cover all applicable states and reject every + same-process legacy+canonical overlap. +- [ ] RED secret bridge cases: + `SecretSource` resolves references only in bootstrap; adapter-owned handles receive versioned + material; missing/blank/malformed secret fails without logging it; no raw key or provider + credential is retained in settings, application values, entities or adapter-owned immutable + records. This is not an end-to-end wipeability claim: the current `SecretSource`/ + `EnvironmentSecretSource` API and JDBC credential APIs necessarily expose short-lived Java + `String` values that cannot be wiped. Only the adapter-facing mutable copy is wiped on close. + Tests prove no logging/exception/settings/entity retention and minimize/shorten source-to-handle + copies; they do not claim erasure of an already-created JVM `String`. +- [ ] RED same-DB topology cases against the canonical Spring infrastructure: + `SpringTransactionPort`, the primary `PlatformTransactionManager`, JPA + `EntityManagerFactory`/physical `DataSource` identity and notification store must resolve to + one topology; configured durable startup fails closed on any mismatch. Do not require or + manufacture a production “representative business repository”: this template intentionally + has no production sample aggregate, and `sample-portfolio` must not leak into the runtime + graph. Keep the real business-row write plus notification append commit/rollback proof in the + Task 10 app-bootstrap integration fixture. Every adopted feature later adds its own + composition contract proving its business store joins this primary transaction manager. +- [ ] RED the complete but inactive transitional cutover surface before any qualification or + deployment. The authenticated batch + `POST /api/admin/notifications/writer-ownership/initialize-legacy` accepts only the reviewed + initial-generation map keyed by the server-known routes, reason and operation token. The + proxied operation loads `NotificationWriterRouteSet` derived from the compiled cutover + catalog, derives the canonical ordered set and digest server-side, rejects missing/extra keys, + and maps only to + `InitializeNotificationWriterFencesOperation`. Neither route revisions outside that catalog + nor a caller-provided route-set digest is authoritative. The separate + `POST /api/admin/notifications/routes/{routeId}/writer-ownership` accepts only + `BEGIN_DRAIN|COMPLETE_SWITCH|ABORT_DRAIN` for one route and maps only to + `SwitchNotificationWriterOwnershipOperation`. BEGIN additionally requires a bounded signed + deployment inventory manifest; the controller maps only its opaque bytes/key revision, while + the application verifier independently authenticates exact environment/DB/route/PRE artifact + and complete node inventory and derives every row/count/digest. A third authenticated + `POST /api/admin/notifications/routes/{routeId}/writer-quiescence-attestations` maps only to + `RecordNotificationWriterQuiescenceAttestationOperation`; request data supplies reviewed drain + generation, a bounded signed quiescence manifest and token, never authoritative zero-fact/ + old-node/permit digests. The verifier authenticates the exact frozen node inventory, each + node's retired/quiesced fact plus irreversible deployment-generation/credential/egress fence, + consumer inventory/count 0 and provider-call-ledger identity/open-count 0. The server uses + post-lock DB time to validate the signer's bounded issued/expires window and record verified + time, snapshots the locked persisted proof registry, permit/holder set and BEGIN + inventory, and derives actor. The exact least-privilege + mapping + is `notification-operator -> notification:cutover,notification:cutover-terminalize, + notification:cutover-attest`; default + `admin` receives none. Controller tests cover 401/403, validation, actor spoof rejection + and DTO/command mapping; composition tests prove distinct interface-based method-security + initializer/terminalizer/switch/attestation proxies and internal-delegate separation. The + switch request + accepts `quiescenceAttestationToken` only for COMPLETE on a + `QUIESCENCE_REQUIRED` route; it is required there and forbidden for + BEGIN/ABORT/HARD_BOUND_PROVEN. Caller-supplied actor, profile/permit/holder/node-set or + zero-fact digests are never authoritative. + The fourth authenticated + `POST /api/admin/notifications/routes/{routeId}/writer-permits/terminalize-expired` maps only + to `TerminalizeExpiredNotificationWriterPermitsOperation`; request fields are exact drain + generation, bounded batch, reason and token. Server derives actor, DB time, persisted registry + and affected permit set. It requires `notification:cutover-terminalize`, has provider I/O 0 + and cannot be invoked through a scheduler or read query. +- [ ] RED/GREEN the Ed25519 verifier before controller composition. Freeze + domain-separated `writer-inventory-manifest-v1` and + `writer-quiescence-manifest-v1` length-prefixed canonical encodings with sorted bounded node/ + fact rows. Cover valid current/retiring issuer key revisions, non-canonical order/encoding, + duplicate/unknown fields, oversized node set, signature/algorithm/key downgrade, wrong + environment/DB/route/artifact/generation/ledger identity, expiry and one-byte mutation. Only + opaque digests may represent node/environment/ledger identity; raw hostnames, credentials and + human PII are rejected from retained evidence. The checked-in closed trust catalog pins allowed + issuer key IDs, public-key digests and current/retiring windows; request/env data cannot + introduce a new trust anchor, and resolved public-key material must match the pinned digest. + The reviewed signed profile/closed catalog, not environment input, pins + `allowedClockSkew` and `acceptanceMargin`; the TTL env value may only tighten the maximum + issuance window and can never relax + `issuedAt - allowedClockSkew <= serverVerifiedAt <= expiresAt - acceptanceMargin`. + Persist the canonical signed payload and signature together with issuer/trust snapshot, + issued/expires/verified times and exact environment/DB/artifact/inventory/ledger identities. + Cover signed zero-node authority, write-time verification, persisted round-trip and startup + re-verification. SQL checks only immutable structure and digests; Java is the cryptographic + authority. Production configuration contains issuer public-key references only, never an + issuer private signing key. +- [ ] RED real-PostgreSQL + MockMvc initialization cases before this surface can be deployed: + exact physical commit before 2xx; commit failure/rollback never returns 2xx; concurrent + different-token initialization has one winner; same-token result-loss replay returns the + committed full route-set result; absent fences plus empty control/data-plane journals succeed, + while partial/existing fence sets, any-nonempty-journal and + route-set/digest/generation/token mismatch fail without mutation. Include a two-route fixture + proving all fences, operation children and every proof-registry row commit atomically, and + that replay returns the stored registry digest rather than refreshing from changed input. + These cases + live in `NotificationWriterOwnershipCommitAckContractTest`. The same test covers physical + commit/failure/result-loss replay and stale-generation rejection for + `BEGIN_DRAIN|TERMINALIZE_EXPIRED_PERMITS|COMPLETE_SWITCH|ABORT_DRAIN`, plus terminalizer and + attestation commit-before-2xx, signed inventory/quiescence issuer and set mismatch, 401/403, + idempotent replay and COMPLETE missing/stale/mismatched-token failures. It pauses an old bridge + after credential/client/connection acquisition but before provider I/O, commits COMPLETE from + an independent transaction, resumes the old bridge and proves provider I/O 0 because its + deployment generation, credential and egress route are irreversibly disabled.

Adding key version v2 means an additive versioned env/secret registry row, + never overwriting v1 while retained rows reference it. +- [ ] Add all public/sensitive keys to `env-keys.yaml` and `.env` with safe blank/default examples. + Add token/AEAD/HMAC and sensitive identity rows to `secrets-classification.yaml`. + Optional notification secrets use an explicit `required_when` condition and are validated only + by `NotificationCompositionValidator` when the matching binding is compiled; disabled mode + performs no secret lookup. +- [ ] Bind only provider/identity/key `*_REF` values into immutable `NotificationSettings`; raw + token/AEAD/HMAC bytes must never be an `application.yml` placeholder or settings field. The + bridge calls `SecretSource.resolve(ref)` only after the canonical graph selects that + provider/key revision. Database runtime/migrator references bind exclusively to + `NotificationDatabaseRoleSettings` and the dedicated runtime/Flyway data-source wiring, never + to application commands/records or `NotificationSettings`. Provisioner references are absent + from the normal application and exist only in the Task 21 provisioning source set. +- [ ] Extend `verifyEnvKeys` narrowly: an `.env` key without an `application.yml` placeholder is legal + only when `secrets-classification.yaml` registers it as `secret-source-only` with a + `required_when` condition. Unknown/orphan public keys still fail. Add the secrets registry as a + task input and tests for allowed secret-source-only, misspelled secret, disabled zero-lookup and + ordinary orphan rejection. +- [ ] Update `SecretsClassificationRegistryTest` so unconditional secret rows still match + `SecretSourceValidator.REQUIRED_PROD_SECRETS` 1:1, while `required_when` rows are excluded from + that global list and are covered by exact notification composition tests. Do not make optional + Notification secrets globally required in prod. +- [ ] Verify RED: + + ```bash + cd src && ./gradlew :app-bootstrap:test \ + --tests '*NotificationCompositionTest' \ + --tests '*NotificationZeroResourceTest' \ + --tests '*NotificationSecretMaterialBridgeTest' \ + --tests '*NotificationCanonicalSameTransactionCompositionTest' \ + --tests '*NotificationCanonicalWriterFenceSetCompositionTest' \ + --tests '*NotificationWriterActivationGateTest' \ + --tests '*NotificationInternalTrustContextCompositionTest' \ + --tests '*FencedLegacyNotificationPortTest' \ + --tests '*NotificationCutoverAuthorizationCompositionTest' \ + --tests '*NotificationWriterOwnershipCommitAckContractTest' \ + --tests '*NotificationSecretEnvContractTest' \ + --console=plain + cd src && ./gradlew :adapter:inbound:web:test \ + --tests '*NotificationWriterOwnershipControllerTest' --console=plain + cd src && ./gradlew :adapter:outbound:notification:test \ + --tests '*Ed25519NotificationWriterInventoryEvidenceVerifierTest' --console=plain + ``` + +- [ ] Bind canonical settings once, derive minimal outbound/inbound/persistence profiles, and pass + application-owned provider/store/ingress capability descriptors to the pure application + compatibility validator. +- [ ] At startup, have `NotificationSameDataSourceTopologyValidator` inspect the canonical + transaction port, primary transaction-manager/JPA resource and notification-store topology + descriptor and reject durable mode unless they share the same physical transaction + manager/data-source identity. Feature-specific business-store atomicity remains an explicit + feature composition test, not a fabricated bootstrap bean. This composition-root invariant + must not introduce a new project dependency edge. +- [ ] Wire exactly the three non-interchangeable PostgreSQL principals + `notification_migrator`, `notification_runtime`, `notification_provisioner` and reject any + additional notification-scoped owner/member/grantee. `notification_migrator` owns the + notification schema and is used only by the dedicated Flyway data source; + `notification_runtime` is a nonowner used by the application transaction manager; the + `notification_provisioner` credential is not composed here and is available only to the + explicit Task 21 provisioning source set. Resolve migrator/runtime credential references + separately, assert `current_user` and ownership/grants at startup, and fail on shared + credentials, owner runtime, role inheritance or unexpected membership. Tests prove runtime + cannot run DDL, mutate retained evidence/provenance directly, use transitional functions or + consume sequences beyond its exact runtime grants, except that the exact PRE artifact grants + runtime only its explicitly enumerated transitional function `EXECUTE` surface and FINAL + revokes that entire surface. Flyway cannot be reached through an application bean. +- [ ] Before resolving either runtime or migrator credentials, require the Task 9 external + DB-admin/IaC bootstrap revision and exact role-inventory/ownership probe from + `docs/runbooks/notification-database-role-bootstrap.md`. Application startup never creates, + alters or grants role membership. Missing/mismatched bootstrap evidence, shared credentials, + unexpected membership or an additional notification-scoped principal fails before Flyway or + runtime table access. +- [ ] Update the existing executable startup seam, not a parallel notification-only migration path. + `MigrationStartupConfig` builds Flyway from the dedicated migrator data source; + `MigrationStartupRunner` asserts its connection `current_user=notification_migrator` before + `migrate()` and never receives the primary runtime data source; + `RequiredEnvironmentValidator` requires the runtime credential refs always and migrator refs + exactly when startup migration is enabled. Keep the DB URL/schema locations common, but make + the credential binding choice explicit: `spring.datasource.*` remains the + `notification_runtime` application data source, while `spring.flyway.user` and + `spring.flyway.password` are intentionally unbound/forbidden so Boot cannot treat secret refs + as credentials or fall back to the runtime principal. The dedicated Flyway data source gets + resolved username/password bytes only from `NotificationDatabaseRoleSettings`; tests fail if + Flyway is constructed from the primary data source, if either role ref aliases the other, or + if migration-on-startup can run without the migrator refs. +- [ ] Invoke `NotificationCanonicalWriterFenceGuard` from canonical intent admission inside the same + business-write/append transaction; configured bindings require an exact checked-in route/fence + generation. A stale generation or non-canonical owner rolls back both business write and intent + append and prevents worker activation. Bootstrap never calls the guard or + `NotificationCanonicalWriterFencePort` directly. +- [ ] Freeze the trust-context wiring matrix: + scheduler/worker/health, feature-internal notification orchestration and legacy bridge use + manually composed non-bean application delegates; verified SNS ingress uses a distinct manually + composed receipt delegate after signature/topology authentication; neither path is subjected to + JWT method security or exposed to a normal controller. Only the transitional human initializer + and cutover operations are registered as Spring method-security beans behind + `InitializeNotificationWriterFencesOperation`, + `TerminalizeExpiredNotificationWriterPermitsOperation`, + `RecordNotificationWriterQuiescenceAttestationOperation` and + `SwitchNotificationWriterOwnershipOperation`. Never reuse any proxied target as an internal + delegate, and never publish the internal delegates as Spring use-case beans. Context tests + assert bean absence/identity separation so schedulers/SNS do not fail for missing + `Authentication` and operator calls cannot bypass AOP. +- [ ] Build the legacy fence wrapper and full operator endpoint in this task, but keep them dark: + no automatic fence initialization, no provider call while the fence is absent, and no rollout + before Wave F qualifies this exact artifact. This ordering is deliberate: Task 19/20 manifests + may say `PRE_CUTOVER_BRIDGE` only when the compiled bridge/operator/permit surface being + deployed in 21A is already present. Task 21A/21B perform human-controlled state transitions + and rerun the same tests; they do not add or alter production code before cleanup. +- [ ] `NotificationSettings` is the only `@ConfigurationProperties` binder. Provider and worker + `*RuntimeProfile` types are plain immutable derived slices with no binding annotation or + independent defaults. +- [ ] `NotificationWriterActivationGate` calls only + `NotificationOperationsSnapshotUseCase` for bounded committed refreshes. It never injects + `NotificationOperationsSnapshotPort`, a repository, entity, `EntityManager` or JDBC type. + Snapshot freshness gates readiness/worker admission, while + `NotificationCanonicalWriterFenceGuard` inside each business-write/append transaction remains + the final authoritative fence. Tests prove stale cache cannot authorize an append and no route + opens before a fresh exact committed snapshot. +- [ ] Collect actual descriptors only from the three adapter-owned descriptor sources. Keep expected + settings as a separate input and add negative tests that mutate each actual source + independently; a validator that derives expected and actual from the same settings is + tautological and must fail review. +- [ ] Default `application.yml` to explicit `disabled`; no blank-is-disabled ambiguity. +- [ ] Add every new env key with type/default/secret classification and safe example; no secret value + in YAML/docs/tests. +- [ ] Verify GREEN with the same command and: + + ```bash + cd src && ./gradlew :adapter:inbound:web:check --console=plain + cd src && ./gradlew verifyEnvKeys \ + verifyCleanArchitectureDependencies --console=plain + ``` + +- [ ] Acceptance claim: exact local composition and disabled resource safety; real provider state + remains unqualified. + +**Rollback checkpoint:** deploy canonical code/config dark. Never enable canonical and legacy for the +same route.

Unsigned/uncommitted/reversible-fence, + provenance-less or ambiguous empty fixtures fail. Its qualification source must compile + and run after all + initializer/switch/permit/terminalizer/attestation types are deleted and must prove those + types/endpoints are absent. + + Both paths require route-set/generation-set plus the stage-specific ownership evidence digest + to match the selected release profile. Direct fence seed SQL outside Flyway, mixed markers, + PRE operation calls in FINAL and stage override all fail. +- [ ] Keep `TestOnlyNotificationWriterEvidenceIssuer` only in the + `notificationQualification` source set. It uses a deterministic local test key and signs the + same canonical inventory, quiescence and DB-birth authorization payloads for repeatable tests; + its manifests are explicitly `LOCAL_TEST`, have a lower evidence grade and cannot satisfy + Task 19 or `notificationProductionReadiness`. Production JAR/config/source sets contain + neither this class nor its private key. The final aggregator accepts production ownership + evidence only from the Task 19 independent issuer client. +- [ ] RED/qualification matrix includes: + claim/finalize contention; provider throttle; callback burst; response loss; DB finalize + outage; key/credential/template rotation; old/new writer HMAC aliases; rolling worker revisions; + park/resume restart; retention/redaction; cancellation/expiry racing wire authorization. +- [ ] Add an actual forked-JVM crash harness, distinct from Task 12's deterministic fault injection. + The parent owns PostgreSQL plus `NotificationAttemptLedgerServer`; each child reports a durable + phase marker and calls `Runtime.halt(91)` at the requested point.

Cover claim, + reserve, immediately before/after committed `WIRE_AUTHORIZED`, possible provider write, + response and finalize; include authorization commit failure and commit-success/result-loss. + No in-process exception may be accepted as process-crash evidence. +- [ ] At every post-authorization ambiguous point, assert request count is at most the exact + card-specific bound, there is no blind retry/fallback, and recovery ends only in an exact + terminal fact, provider reconciliation, or explicit `INDETERMINATE`. +- [ ] Extend the manifest schema/test for the local qualification and final aggregate rows, then run + it GREEN before registering/executing qualification. Every local/provider/DLQ/aggregate row + carries the detector-derived immutable `release_stage`, and the aggregator requires all input + rows to match its own artifact stage. Model ownership evidence as a closed discriminated union: + `PRE.QUIESCENCE` requires only signed BEGIN inventory, signed + quiescence/attestation header + trust snapshot, irreversible node/credential/egress facts, + ACTIVE 0, consumer/ledger 0 and cutover history; `PRE.HARD_BOUND` requires only signed BEGIN + inventory, the all-hard-bound registry/evidence revision, safe terminal permits and ACTIVE 0, + and forbids the attestation. `FINAL.FRESH` requires only cleanup/V8 structural evidence, + discriminator `FRESH_PROVISIONED` with fresh token and null validated-history digest, signed DB + birth certificate, the complete exact Task 9 fresh-provenance field set and + enforcement-read-back → cached-session/flow termination → post-enforcement zero manifest + (provider-ledger entry/open/indeterminate 0) → irreversible fence seal/read-back → signature + causal order, signed fresh provenance/trust snapshot and `INITIALIZE_CANONICAL_FRESH`; + `FINAL.UPGRADE` requires only + cleanup/V8 structural evidence, discriminator `UPGRADE_VALIDATED` with complete retained-history + digest and null fresh token, and forbids fresh provenance.

After 21C every legacy key is + unknown and fails startup. +- [ ] Before bridge admission opens, deploy the exact Wave F-qualified + `PRE_CUTOVER_BRIDGE` artifact, which already contains the inactive transitional operator + controller and exact least-privilege mapping + `notification-operator -> notification:cutover,notification:cutover-terminalize, + notification:cutover-attest`; default `admin` + inherits none. Its + authenticated `INITIALIZE_LEGACY` action derives actor from + `AuthenticatedPrincipal` and calls only the method-security-proxied + `InitializeNotificationWriterFencesOperation`. A human supplies the reviewed initial + predecessor generations (`configured canonical target - 1`) for the server-disclosed exact + route set, reason and operation token; the + operation derives the ordered route set/digest from the compiled catalog.

Direct SQL, + sequential per-route or automatic bootstrap initialization is forbidden. +- [ ] Re-run the already implemented Task 17 `FencedLegacyNotificationPort` tests without changing + the qualified source/artifact. The wrapper calls + `NotificationLegacyWriterPermitUseCase` to reject ambient transactions and root-commit a + bounded permit before provider I/O, then root-commit release afterward. Acquire commit failure + means provider call 0; release failure leaves the lease visible and blocks switch until guarded + recovery/expiry. Canonical guard failure rolls back business state and intent append together. +- [ ] A permit expiry becomes `EXPIRED_PROVEN` only when the catalog transport profile proves an + acquire-committed DB-time absolute wire deadline, network-start refusal after it, connection + close/cancellation by it and + `wire deadline + finalize margin <= permit expiry` in an integration evidence revision, + including acquire-commit→process-pause→expiry→resume call 0. Current R0 is + `QUIESCENCE_REQUIRED`, so timeout becomes `TIMED_OUT_UNPROVEN`; stop 21B until a post-BEGIN + authenticated attestation verifies a trusted signed manifest over the exact BEGIN-frozen + complete old-node inventory, per-node irreversible retirement/credential/egress fencing, + consumer inventory/count 0, + provider-call-ledger identity/open-count 0 and the server-derived persisted-registry/ + TIMED_OUT_UNPROVEN/holder sets.

COMPLETE instead requires the already accepted signed + retained header plus exact irreversible deployment-generation/credential/egress facts, + ACTIVE 0 and provider-ledger 0. A crashed/release-failed ACTIVE permit is changed only after BEGIN by + the authenticated `notification:cutover-terminalize` operation; repeat bounded batches until + the read-only snapshot reports ACTIVE 0.

Any code/config/lock + change after Wave F invalidates its manifest and requires all Task 19/20 PRE lanes to rerun + before deployment. + +#### Task 21B — route-specific ownership switch and observation + +- [ ] Reuse the Task 17/Wave F-qualified authenticated + batch initialization, expired-permit terminalization, route ownership and route + quiescence-attestation endpoints; do not add or extend production code between PRE + qualification and this switch. None is a public path. + Existing JWT/method-security enforcement requires `notification:cutover` for initialization + and switch, `notification:cutover-terminalize` for terminalization, and + `notification:cutover-attest` for attestation. The thin controller maps the + reviewed generation map/reason/token only to `InitializeNotificationWriterFencesOperation`; + that operation, not request data, supplies the compiled exact route set/digest. The controller + validates exact route/action (`BEGIN_DRAIN|COMPLETE_SWITCH|ABORT_DRAIN`), expected + generation, reason and operation token before mapping switch actions only to + `SwitchNotificationWriterOwnershipOperation`. BEGIN also maps a bounded signed inventory + manifest, never a caller-authored node digest; the application verifier derives and freezes the + exact server-trusted set. It derives the audited actor from + `AuthenticatedPrincipal`, never request data; target/expected owner is not a request field. + Direct SQL/repository access and bootstrap + handlers are forbidden. COMPLETE on a `QUIESCENCE_REQUIRED` route must carry the exact + `quiescenceAttestationToken`; the attestation endpoint maps a signed quiescence manifest, and + other actions/profiles reject those fields. +- [ ] Reconfirm the exact 21A least-privilege role mapping and the already registered distinct + interface-based initializer, terminalizer, attestation and switch targets as method-security + proxied Spring + beans; + the controller has no duplicate permission annotation and cannot obtain the manual internal + delegate. `NotificationCutoverAuthorizationCompositionTest` proves proxy creation, authorized + initializer/terminalizer/attestation/switch success, admin/missing-role 403, internal no-auth + delegates + still work, and + no final-class/proxy startup failure.

Pause an old node with cached + credential/client/connection before provider I/O, commit COMPLETE from another transaction, + resume the old node and prove provider I/O 0 under revoked deployment generation, credential + and egress. The inbound leaf never imports persistence to make this claim: + + ```bash + cd src && ./gradlew :app-bootstrap:test \ + --tests '*NotificationWriterOwnershipCommitAckContractTest' --console=plain + ``` + +- [ ] Roll canonical-only config nodes while the shared owner remains `LEGACY@g`; PRE composition + derives `CUTOVER_WAIT`. Those nodes are liveness-healthy but readiness reports + `CUTOVER_WAIT`, and their admission/claim/provider-call counts remain 0 while bridge nodes may + still acquire legacy permits. No node has both config grammars. +- [ ] After canonical-ready nodes are liveness-healthy in `CUTOVER_WAIT`, a human first invokes + `BEGIN_DRAIN` with an independently issued short-lived manifest of the complete + environment/DB/route/artifact old-writer node set. The root transaction verifies its signature, + rejects any known permit holder omitted from the inventory, freezes every node row/count/digest, + and closes new legacy permit acquisition. Poll active permit count/max expiry through + `NotificationOperationsSnapshotUseCase` outside a transaction. The count includes ACTIVE + legacy permits for the route across all old/current fence generations and does not ignore a + row merely because `expires_at` passed; only an exact terminal CAS removes it from the count. + For expired ACTIVE rows, call the authenticated terminalizer in bounded batches. It checks the + exact DRAINING generation and persisted registry, records the affected immutable set in the + operation journal and commits before 2xx; poll again until ACTIVE 0. + For the current `QUIESCENCE_REQUIRED` R0 profile, only after that committed BEGIN and ACTIVE + count 0, obtain an independently signed manifest that lists the exact frozen node set, every + node's retired/quiesced fact plus deployment-generation tombstone and legacy + credential/egress revocation, production consumer inventory/count 0 and provider-call-ledger + identity/open-count 0. Call the authenticated quiescence-attestation endpoint with that opaque + manifest. Its root transaction verifies the issuer/environment/DB/artifact/generation, derives + the catalog-equality-checked persisted profile set and locks/snapshots every-generation + `TIMED_OUT_UNPROVEN` `(token,generation,profile,state,rowVersion)` plus distinct permit-holder + sets, then requires exact node equality/holder subset and commits the derived evidence. + Invoke `COMPLETE_SWITCH` with that exact attestation token; it locks and recomputes the same + sets and rejects missing/mismatched evidence, reversible or absent + tombstone/credential/egress facts, a changed consumer/provider-ledger identity, nonzero ledger + state or any ACTIVE permit. Before either COMPLETE arm, Java reverifies the retained signed + BEGIN inventory canonical payload, signature, issuer public verification material, trust + snapshot, issued/expires/verified acceptance and header/child semantic equality. + QUIESCENCE_REQUIRED additionally reverifies the retained signed attestation bundle. Expiry + controls admission of new signed evidence, while accepted irreversible facts remain durable. + For a genuinely `HARD_BOUND_PROVEN` profile, every permit must instead be + `RELEASED|EXPIRED_PROVEN`, the COMPLETE request forbids an attestation token, and the valid + retained signed BEGIN remains mandatory. + After the applicable proof, invoke `COMPLETE_SWITCH`; its + `inRootWrite` CAS to route-specific `CANONICAL@g_final/ACTIVE` must physically commit before + success is reported. Missing durable evidence or a stale-node resume that can reach a provider + leaves the route DRAINING and makes the rollout `NOT_QUALIFIED`. `ABORT_DRAIN` is the only + rollback operation and emits a new LEGACY + generation, so one or more aborts make `g_final` greater than the naïve `g+1`; none of these + operations waits or sleeps inside the use case. Any abort makes the prior expected-generation + profile and PRE manifests stale. Update + `APP_NOTIFICATION_EXPECTED_WRITER_GENERATIONS`, reproduce the resulting generation set through + the same audited sandbox operations, and rerun all required Task 19/20 PRE lanes before the + next expansion/switch decision. +- [ ] On each committed `COMPLETE_SWITCH`, `NotificationWriterActivationGate` opens only the matching + route on canonical `CUTOVER_WAIT` nodes after a fresh committed read; its notification + readiness becomes ready only when every configured route is at its exact target. Old bridge + nodes observe the canonical owner and keep that route closed. No restart/config watcher may + infer activation before the database fact. +- [ ] Define observation abort thresholds before the switch: any duplicate occurrence, any new + unexpected `INDETERMINATE`, oldest-backlog age over the route SLO, receipt lag over the + callback SLO, non-zero unplanned DLQ depth, or parked-gate count above the reviewed bound pauses + admission and aborts expansion. Do not automatically resend while diagnosing. +- [ ] Keep both code paths packaged during the reviewed observation window, but treat a committed + `COMPLETE_SWITCH` as forward-only. `ABORT_DRAIN` is valid only while the route is + `DRAINING/LEGACY`; there is no CANONICAL→LEGACY CAS or legacy re-enable after COMPLETE. + On a post-COMPLETE threshold breach, close canonical admission and workers through the shared + gate, inventory accepted/indeterminate/in-flight work, avoid replay and forward-fix. Any future + reverse handoff requires a separate canonical-drain/backlog/provider-result protocol, + duplicate policy, design approval and provider requalification. + +#### Task 21C — cleanup release + +- [ ] Before reserving `V8`, rescan every Flyway location; if occupied, use the next global version + and update the plan first. V8 is validation/preparation only and has two closed outcomes: + + - `UPGRADE_VALIDATED`: V8 establishes the Task 9 singleton discriminator in this exact state with a + server-canonical digest of the complete validated retained history, null fresh token and + absent signed fresh provenance. V8 inserts no fence or cutover history and preserves the + existing canonical fence/history/evidence rows byte-for-byte. The persisted route key set + exactly matches the reviewed set; every fence is + `ACTIVE/CANONICAL@g_final`, its latest pointer resolves to a matching committed + `COMPLETE_SWITCH`, and the complete legacy initialization→switch history passes the + structural validation below. A route with no complete history fails even when notification + data happens to be empty. + - `AWAITING_SIGNED_FRESH_PROVISIONING`: only an exact-empty V1..V8 notification + data/control/fence/history/evidence inventory may reach this state. V8 inserts no canonical + fence, provenance or initialization operation and writes a discriminator having neither + fresh token nor validated-history digest. Any nonempty inventory with a missing, partial or + noncanonical fence set fails; an awaiting marker on existing history is tampering. + Application admission, claim, worker and provider resources remain dark. + + Fresh initialization is an explicit post-migration operation, never Flyway lifecycle work. + Register the opt-in `:app-bootstrap:notificationFreshProvisioning` Gradle task backed by + `NotificationFreshProvisioningCli`; `NotificationFreshProvisioningSettings` binds only the + narrow authorization/public-key/provisioner refs listed below, and the CLI composes + `ProvisionFreshNotificationWriterFencesOperation` and the PostgreSQL implementation only in + the dedicated source set and is not attached to `test`, `check`, application startup or + Flyway. Register a separate `notificationFreshProvisioningTest` source set/task for its CLI + integration tests; that test task also stays out of ordinary `test`/`check`. The independent + infrastructure issuer signs a domain-separated + `notification-fresh-provisioning-v1` canonical payload binding authorization nonce/token, + environment, a database birth certificate with DB-system/database/schema identity and birth + token/revision/digest/`committedAt`, final source/artifact digest, exact canonical + route/generation set, and every exact Task 9 + `notification_fresh_installation_provenance` field. The issuer control plane must first + commit/read back the irreversible enforcement revision and all deployment-generation, + credential-issuance/revocation, DB-ingress and provider-egress deny facts; then terminate + cached legacy DB sessions and provider connections/flows; then observe the causally later + post-enforcement workload/business-consumer/node/session/flow zero manifest and provider + ledger settled cut with entry/open/indeterminate counts 0; then seal-commit/read back the + permanent irreversible fence; and only then sign. The canonical payload retains the exact + enforcement/fence canonical payloads, revisions, digests and activation/commit/read-back + times, post-enforcement manifest payload/digest/revision/time, ledger cut revision/time, + credential and denial-policy digests/booleans, + `legacy_database_session_inventory_digest`, + `legacy_database_session_open_count=0`, + `legacy_database_session_termination_evidence_digest`, + `legacy_provider_connection_flow_inventory_digest`, + `legacy_provider_connection_flow_open_count=0`, + `legacy_provider_connection_flow_termination_evidence_digest`, and both + established-flow-block facts. Every source evidence binds the same fence token and + enforcement revision. The independent issuer refuses pre-enforcement zero, cross-revision + composition, sign-before-seal, unsigned, uncommitted or reversible evidence. The retained + provenance stores those canonical + payload bytes, Ed25519 signature, bounded issuer public-key SPKI, key ID/digest, closed trust + snapshot and issued/expires/server-verified times. The signed profile pins + `allowedClockSkew` and `acceptanceMargin`; Java admits it only when + `issuedAt - allowedClockSkew <= serverVerifiedAt <= expiresAt - acceptanceMargin`, verifies the + stored payload/signature/SPKI, and requires the historical-key digest to remain allowed and + non-revoked in the current closed catalog. Unknown/duplicate fields, noncanonical encoding, + algorithm/key downgrade, wrong identity, nonzero authority, missing/reversible fence, stale + birth certificate or token mismatch fail. + + `ProvisionFreshNotificationWriterFencesUseCase` rejects an ambient transaction and owns the + orchestration inside `TransactionPort.inRootWrite`. The dedicated provisioning composition + creates a provisioner-only `DataSource`, `PlatformTransactionManager` and + persistence-owned `PostgreSqlNotificationProvisionerTransactionAdapter` implementing + `TransactionPort`; none is a normal runtime/Flyway bean and the adapter proves its connection + has `current_user=notification_provisioner`. App-bootstrap owns only the dedicated data-source/ + transaction-manager composition and does not implement the transaction adapter. + `NotificationFreshProvisioningPort` exposes exactly two methods: + `snapshotAndReadLock(...)` and `applyVerifiedProvisioning(...)`. In one physical provisioner + connection/transaction the use case (a) calls `snapshotAndReadLock` for the exact + awaiting/empty inventory, server DB clock and DB identity, (b) passes that authoritative + snapshot and signed bytes to + `NotificationFreshProvisioningAuthorizationVerifierPort`, then (c) sends only the verified + facts to `applyVerifiedProvisioning`. The two calls may not use a second connection, nested + transaction, autocommit or a runtime/migrator transaction manager. + `PostgreSqlNotificationFreshProvisioningAdapter`, under `.postgresql.provisioning`, implements + only those structural lock/snapshot/CAS/insert operations; it never calls the verifier or owns + application policy. V8 exposes exactly two migrator-owned `SECURITY DEFINER` functions, + `notification_fresh_provisioning_snapshot_and_lock(...)` and + `notification_fresh_provisioning_apply(...)`, one for each port method. The apply function + proves the first function ran in this same physical transaction by checking its + transaction-local lock/snapshot proof, rechecks that those discriminator/inventory locks are + still held, and compares the first-stage DB-computed snapshot digest. It then rechecks + `AWAITING_SIGNED_FRESH_PROVISIONING`, store emptiness, current DB identity and the canonical + payload semantic digest from authoritative inputs, obtains a fresh `clock_timestamp()` and + rechecks the signed issued/expires/skew/acceptance window. A direct apply without the exact + first-stage lock ownership and snapshot digest fails before DML. It persists that apply-time DB value as + `server_verified_at`; a Java pause that crosses expiry yields mutation 0 even if the first + snapshot was valid. The root transaction inserts immutable signed provenance, exactly one + `INITIALIZE_CANONICAL_FRESH` header with the complete ordered route children, every + `ACTIVE/CANONICAL@initial` fence and CASes the discriminator to `FRESH_PROVISIONED` with its + fresh token and null validated-history digest. The operation returns its result only after + physical commit. A committed same-token/same-payload replay is a read-only result-recovery + branch: both functions lock/recompute the retained discriminator/provenance/init/fence + equality, Java reverifies the stored signature/trust/semantic facts and original + `server_verified_at` acceptance, and apply returns the persisted result without DML. It does + not apply current wall-clock expiry to that already accepted irreversible fact. A missing + result, different token/input/identity/digest, partial state or attempted new mutation must + take the fresh-time new-mutation branch or fail closed. Thus commit-success/result-loss is + recovered without a second initialization. Startup + remains dark until this transaction is durably committed, then a fresh startup re-verifies the + retained signed provenance in Java and may enter `REQUIRE_CANONICAL`. SQL enforces only + structural shape/count/digest/FK/immutability; it is never the Ed25519 authority. Authorization + expiry after accepted provisioning does not reverse the committed provenance or fences. + + Before V8, external DB-admin/IaC has already created the exact three-role set from Task 9. + V8 validates that set, ownership and grants and never executes `CREATE ROLE` or creates the + principal running itself. `notification_migrator` owns the schema, Flyway + history, migration objects and the two narrowly scoped provisioning functions. + `notification_runtime` is a nonowner. `notification_provisioner` has no table DML, sequence, + ownership, role-membership or DDL privilege and receives only `EXECUTE` on those exact two + functions. Both `SECURITY DEFINER` functions are migrator-owned, use + `SET search_path = pg_catalog` plus fully qualified objects, contain no dynamic SQL or + caller-selected object/action, check the exact caller role and lock their state/token/payload + rows; `PUBLIC` and runtime execute are revoked. PRE runtime retains only its separately + enumerated transitional `EXECUTE` grants until FINAL, when V8/cleanup revokes them. Tests reject + owner substitution, inherited membership, search-path shadowing and direct DML/sequence access. + Apply becomes state-closed after success; retained same-token replay is the only allowed result + path. + + On upgrade, replay the full causal journal by the operation and attestation values allocated + from the same DB sequence after the global/route fence lock: + `INITIALIZE_LEGACY -> (BEGIN -> TERMINALIZE* -> ABORT)* -> + BEGIN -> TERMINALIZE* -> COMPLETE`. Each non-init child has the exact drain-BEGIN FK; + expected/result owner/state/generation matches the closed matrix, terminalizer is unchanged + DRAINING, and COMPLETE is the last mutation. CANONICAL→BEGIN/TERMINALIZE/ABORT/ + second-COMPLETE, cross-table sequence collision/reversal, missing predecessor or + replay/fence/latest-pointer mismatch fails. `recorded_at`, `terminalized_at` and `observed_at` + must be post-lock `clock_timestamp()` values but are only sanity evidence; sequence/FK is the + causal SSOT. + + Reject orphan header/child, empty child set, action mismatch and any server-canonical + `route_set_digest`/`request_input_digest` recomputation mismatch, including terminalizer batch + bound. Both INITIALIZE actions have the exact reviewed all-route child set; every non-init + header has exactly one child. The retained immutable transport-proof registry, not the deleted + PRE catalog or caller digest, is upgrade proof authority: exact route/current+retiring profile + set, one ACTIVE profile, shared route digest and initialization-child FK; every frozen permit, + attestation and COMPLETE profile/proof/evidence/digest matches it. ACTIVE permits fail. + All-HARD_BOUND history requires the retained signed BEGIN header, an exact all-hard-bound + registry/evidence revision and permits only `RELEASED|EXPIRED_PROVEN`; ACTIVE permit 0 is + mandatory and quiescence attestation/children are forbidden. + + Every terminal permit composite-references its exact unchanged-DRAINING terminalizer child, + satisfies `expires_at <= terminalized_at` and + `BEGIN.operation_sequence < terminalizer.operation_sequence < + first-closing.operation_sequence`, and participates in the recomputed affected count/set + digest. QUIESCENCE_REQUIRED history additionally requires: BEGIN's signed complete-node + count/set/manifest digest exactly equals every immutable node row; all distinct permit holders + are included; attestation references that BEGIN and exact registry/permit/holder/node sets plus + independently signed per-node irreversible retirement/credential/egress fencing, consumer + inventory/count 0 and provider-call-ledger identity/open-count 0. The retained inventory and + quiescence/attestation headers and trust snapshots structurally bind the canonical signed + payload/signature, issuer public-key SPKI/key digest, issued/expires/verified fields and exact + environment/DB/artifact/inventory/ledger identities. Causal validity is + `BEGIN.operation_sequence < attestation.attestation_sequence < + COMPLETE.operation_sequence`, not a pre-commit timestamp. Current cleanup time is irrelevant. + A superseded/unselected attestation is allowed only with the same BEGIN and sequence before + the first closing ABORT/COMPLETE. Missing/extra/forged inventory, holder, attestation, + irreversible fact, provider-ledger snapshot or sequence fails. V8 performs structural + validation only; before activation Java re-verifies every stored payload/signature/SPKI, + applies the historical-key allow/non-revoked decision from the current closed catalog and + rejects a malformed acceptance window. Evidence accepted inside its pinned window remains + durable after expiry. Preserve fence, registry, permit, node inventory, per-node quiescence + evidence, signed headers/trust snapshots, attestation, provenance and operation rows + byte-for-byte. +- [ ] Implement the retained FINAL read path as a separate bounded application contract. + `NotificationRetainedWriterEvidenceQuery` supplies only expected environment/DB/artifact, + canonical route/generation set and reviewed per-collection bounds; + `NotificationRetainedWriterEvidenceQueryPort` returns one immutable + `NotificationRetainedWriterEvidenceSnapshot`. + `PostgreSqlNotificationRetainedWriterEvidenceQueryAdapter` performs read-only, deterministic + ordered reads and fails on truncation, extra rows, duplicate identities or any bound breach. + For `FRESH_PROVISIONED` it reads the discriminator, fresh provenance, exact + `INITIALIZE_CANONICAL_FRESH` header/children and exact canonical fence set. For + `UPGRADE_VALIDATED` it reads the discriminator plus the complete operation/route-child, + transport-proof registry, permit, BEGIN inventory/header/child, quiescence/attestation + header/child, trust-snapshot and exact canonical-fence snapshot needed to recompute the stored + validated-history digest. Awaiting or an arm overlap is never activation evidence. + `VerifyRetainedNotificationWriterEvidenceUseCase` is the only application-facing verifier. It + passes each bounded canonical payload/signature/SPKI/trust bundle to + `NotificationRetainedWriterEvidenceVerifierPort`; + `Ed25519NotificationRetainedWriterEvidenceVerifier` owns canonical decoding, Ed25519 + verification, issuer SPKI/digest, pinned trust snapshot and current closed-catalog + allow/non-revoked checks, and returns only bounded typed verified facts. The use case owns + branch policy: it compares those facts for exact semantic equality with the relational + projection, then checks discriminator XOR/token/history digest and exact catalog/generation + equality. Neither adapter makes branch/activation decisions, and the inventory-only + `NotificationWriterInventoryEvidenceVerifierPort` is not reused as if it covered fresh + provenance or the full FINAL snapshot. + App-bootstrap startup and readiness inject only this use case; composition/startup tests forbid + direct injection/import of a retained repository, JPA entity, `EntityManager` or JDBC type and + prove both exact arms activate only after successful Java verification. +- [ ] Register the following provisioning-source-set-only inputs; none is a + `NotificationSettings` field or normal runtime/Flyway input: + + | env key | purpose | classification | + | --- | --- | --- | + | `APP_NOTIFICATION_FRESH_PROVISIONING_AUTHORIZATION_REF` | externally issued signed DB-birth + committed irreversible-fence authorization bytes | sensitive reference | + | `APP_NOTIFICATION_FRESH_PROVISIONING_ISSUER_PUBLIC_KEY_REFS` | bounded verifier public-key SPKI refs matching the closed trust catalog | public verification-material refs | + | `APP_NOTIFICATION_DB_EXPECTED_PROVISIONER_ROLE` | exact callable principal | fixed `notification_provisioner` | + | `APP_NOTIFICATION_DB_PROVISIONER_USERNAME_REF` | dedicated provisioner username reference | sensitive reference | + | `APP_NOTIFICATION_DB_PROVISIONER_PASSWORD_REF` | dedicated provisioner password reference | sensitive reference | + + The CLI never logs or retains credentials in settings/application records/entities and wipes + only adapter-facing mutable copies on close. Do not claim end-to-end erasure: current + `SecretSource`/`EnvironmentSecretSource` and JDBC username/password APIs necessarily create + unavoidable short-lived immutable Java `String` values. Minimize copies and lifetime, run the + CLI as a dedicated forked process, assert `current_user`, immediately close the provisioner + `DataSource` and process after commit/failure, prohibit heap dumps for that process, rotate + short-TTL credentials, and prefer workload identity or certificate authentication where the + JDBC/runtime platform supports it. Tests cover no logging/exception/settings/entity retention, + minimum bridge copies, immediate close and mutable-copy wipe; residual JVM `String` exposure is + explicitly recorded rather than represented as wiped. The CLI carries no signing capability: + a production private key is forbidden in source, artifact, environment registry, test resource + and material source. Supplying these refs to an upgrade/runtime process, omitting one for + explicit fresh provisioning, sharing provisioner/runtime/migrator credentials or mismatching + the pinned SPKI digest fails closed. Retained provenance keeps the canonical payload, signature + and public verification/trust snapshot needed for future Java re-verification, never a private + key or database password. +- [ ] After registering `notificationFreshProvisioning` and + `notificationFreshProvisioningTest` with their exact application/outbound/persistence + classpaths, make the production provisioning configurations inherit only app-bootstrap's + already-governed main `implementation`/`runtimeOnly` configurations and its test + configurations inherit only the governed test configurations. Add an exact project-edge + assertion that scans every provisioning production/test configuration and rejects any direct + or inherited project dependency outside app-bootstrap's registry allowlist. + Register a non-mutating `notificationFreshProvisioningCheck` aggregate that compiles the + production provisioning source set with the repository's Java/Error Prone/static-analysis + policy and runs the project-edge and dependency/lock assertions, but does not run + `notificationFreshProvisioningTest`, invoke the provisioning CLI or reach a database.

Keep both outside ordinary `check` while requiring both explicitly in Task 22. + Regenerate and verify the app-bootstrap lock before compiling or invoking either task: + + ```bash + cd src && ./gradlew :app-bootstrap:resolveAndLockAll \ + --write-locks --console=plain + cd src && ./gradlew :app-bootstrap:verifyDependencyLocks --console=plain + cd src && ./gradlew :app-bootstrap:notificationFreshProvisioningCheck --console=plain + ``` + +- [ ] RED/GREEN real-PostgreSQL migration cases: + a clean V1..V8 two-route database ends only in + `AWAITING_SIGNED_FRESH_PROVISIONING`, with fence/provenance/initialization rows 0 and application + provider resources 0. Invoking `notificationFreshProvisioning` with valid authorization then + creates the complete reviewed canonical initial set, exact retained provenance and one + `INITIALIZE_CANONICAL_FRESH` batch in one transaction and transitions the discriminator to + `FRESH_PROVISIONED` with fresh token present/validated-history digest absent. A valid canonical + upgrade ends only in `UPGRADE_VALIDATED` with complete-history digest present/fresh token and + provenance absent; every XOR/state violation is rejected. V8 rejects every nonempty/partial + notification inventory without an exact canonical fence set; the operation rejects + manually inserted/spoofed/expired/wrong-DB/wrong-environment/wrong-artifact/wrong-route-set/ + nonzero-node, nonzero-consumer or nonzero provider-ledger entry/open/indeterminate-count + authorization, missing/wrong DB birth certificate, every missing/mutated Task 9 enforcement, + post-enforcement zero-manifest, fence-read-back, credential, denial-policy, session or + connection-flow axis, and awaiting-state mutation.

Prove boundary failures around both allowed + clock skew and acceptance margin. Assert both port calls/functions use the same + physical connection/root transaction; pause Java verification beyond expiry and require apply + mutation 0, invoke the apply function directly after expiry and require mutation 0, and cover + rollback after each write stage plus commit-success/result-loss recovery. A failed provisioning + transaction leaves awaiting state unchanged; same-token/same-payload retry is exact and + mismatch retry fails rather than reclassifying a partial database or blessing an upgrade. + A committed same-token replay after current authorization expiry reverifies the stored + signature/trust/semantic facts and original `server_verified_at`, returns the stored result + with DML 0 and never refreshes acceptance time. Direct apply without the first-stage + transaction-local lock/snapshot proof fails with mutation 0. Also invoke both functions + directly outside the CLI/use-case seam with forged signature or + forged typed facts: regardless of any structurally written row, FINAL startup/readiness Java + verification must detect payload/SPKI/trust/semantic inequality and remain dark/ + `NOT_QUALIFIED`. A valid signed authorization may reach direct apply only when every + apply-time DB-clock/fence/state/identity condition still holds, and provider I/O remains 0 + until a subsequent startup successfully re-verifies the retained evidence. + A multi-route upgrade with different valid `g_final` values preserves every fence and + proof-registry/permit/node-inventory/quiescence-node-evidence/signed-header/trust-snapshot/ + attestation/ + operation-history row + byte-for-byte.

Repository policy is `human-only`: do not stage, commit, +> amend, or push. + +**Goal:** Replace the caller-keyed, whole-object `byte[]` example with a framework-free, +bounded-streaming object publication capability, migrate the sample Poster workflow through a +durable database/object-storage handoff, and qualify only exact provider/card combinations for +which the required evidence exists. + +**Architecture:** `application-core` owns provider-neutral identities, content callbacks, requests, +receipts, outcomes, and narrow outbound ports under `dev.caskeleton.application.objectstorage`. +`adapter:outbound:objectstorage` owns immutable data/control namespaces, canonical codecs, +operation state machines, provider bindings, filesystem/S3 implementations, reconciliation, and +readiness evidence. The legacy `dev.caskeleton.application.storage` CRUD contract remains isolated +until the sample and stored data have migrated. `sample-portfolio` owns the business `UploadIntent`, +database attachment choreography, and public HTTP contract; the object-storage adapter never reads +the sample database. + +**Tech Stack:** Java 21, Spring Boot 4.0.0 configuration properties/autoconfiguration, Gradle +multi-module verification, JUnit 5, AssertJ, jqwik `1.9.1`, AWS SDK for Java v2 `2.30.0`, +`S3AsyncClient` with the Java Netty NIO HTTP client, Testcontainers `2.0.2`, version-pinned MinIO, +Toxiproxy, PostgreSQL/Flyway for the sample workflow, Micrometer/Actuator. + +**Authoritative design:** +[Object Storage Production Capability Deep Design](../specs/2026-07-28-objectstorage-production-capability-design.md). +When this plan and that design differ, stop and amend the design before implementing. Module edges +remain governed only by `src/config/architecture/modules.json`. + +**Scope boundary:** This is the executable master plan for design Phases 0–6. It deliberately does +not claim that all tasks belong in one pull request or release. Phase 7 multi-node/R3 work, a +provider-leaf split, a production malware-scanner implementation, and browser API product choices +outside the approved contracts require follow-up plans. Writing this plan changes no runtime +behavior and advances no readiness card. + +**Implementation checkpoint (2026-07-28):** The Batch A–B application/kernel/local-provider +baseline and the Batch C–D S3/MinIO managed/direct primitive slices are implemented and verified in +`codex/objectstorage-production-capability`. Exact MinIO qualification proved that create-only PUT +and multipart completion conditions are ignored, so its managed/direct mutation profiles remain +`UNSUPPORTED`. AWS lanes compile only and have no observed evidence. Only the exact local managed +single upload/download cards remain R1; every direct, multipart, quarantine, retention, and +production reconciliation card remains R0. The exhaustive R2 fault/race matrices named by +unchecked steps remain follow-up evidence, not implied completion. The legacy provider and Poster +consumer remain isolated behind explicit sample-local/test activation. Evidence: +[Batch A](../../evidence/object-storage/batch-a-checkpoint.md), +[Batch B](../../evidence/object-storage/batch-b-checkpoint.md), and +[Batch C](../../evidence/object-storage/batch-c-progress.md), +[Batch D](../../evidence/object-storage/batch-d-checkpoint.md). + +Batch E의 개별 focused fix 증거는 +[Batch E pause checkpoint](../../evidence/object-storage/batch-e-pause-checkpoint.md)에 기록됐다. +당시 Batch E combined/root gate는 재실행되지 않았으므로 Batch E 전체 완료나 R2를 주장하지 +않는다. 격리 브랜치에서 잘못 선택했던 private vault 경로 대신, main 통합 작업은 사용자가 +지정한 public vault의 `raw/branch-notes/chore-main-worktree-capability-integration.md`에 +캡처했다. + +--- + +## Execution rules + +1. Execute batches in order. A later batch may start only after the preceding checkpoint passes. +2. Within a task, write the named failing test first, run the stated RED command, make the minimum + implementation, then run the same command GREEN. +3. A compilation failure counts as RED only when the missing symbol is the symbol the task is + intentionally introducing. Dependency, formatting, daemon, Docker, credential, or unrelated + compilation failures do not count. +4. Preserve the legacy port as an isolated compatibility seam. New business code must never import + `dev.caskeleton.application.storage`. +5. Do not expose AWS SDK, Spring, `Path`, bucket, raw key, provider endpoint, raw ETag, upload ID, + persistent provider locator, or inbound DTO types through `application-core`. A bounded + presigned URI exists only in the explicit transient direct-grant value, is always redacted, and + is never persisted in a receipt/control record. The only raw-locator exception is the exact, + deprecated, admin-only `dev.caskeleton.application.storage.migration` adoption seam in Task 24; + its value is bounded, redacted, never logged/serialized into a receipt, and may not be injected + into a normal business use case. +6. Do not call a producer while a database transaction is open. Do not claim that a database + rollback reverses an object mutation. +7. Unsupported provider behavior is a typed rejection or startup failure, never a fallback, + check-then-overwrite emulation, test skip, or weaker silent guarantee. +8. `filesystem-local-dev` and the pinned MinIO topology have an R1 ceiling. AWS S3 also remains + below R2 until the Phase 6 protected qualification lane passes for an exact provider, destination + profile, card, and evidence revision. +9. Run Spotless only on files changed by this plan. Do not format or rewrite unrelated dirty files. +10. At every batch boundary, update the implementation-status section in the design and this plan. + Do not mark a task complete from code inspection alone. +11. Every Batch A–F checkpoint is a meaningful-work capture boundary. Re-read the canonical LLM + Wiki instructions, update the branch note and any honest derivatives, or record the exact + canonical-vault access block in both this plan and the design before starting the next batch. + A final Task 30 capture does not replace these per-batch records. + +## Frozen implementation decisions + +These decisions translate §37 of the design into executable constraints. A row marked +**approval gate** is intentionally not delegated to an implementation task. + +| Concern | Decision for this plan | +| --- | --- | +| Application package | New contract lives under `dev.caskeleton.application.objectstorage` with `identity`, `content`, `model`, `request`, and `port` subpackages. | +| Legacy coexistence | `dev.caskeleton.application.storage.ObjectStoragePort` and `StoredObject` become deprecated legacy-only types. They remain readable until sample data migration, dual-read observation, API snapshot approval, and zero production usages are evidenced. | +| Control format | `canonical-json-v1`: UTF-8, fixed field order, no insignificant whitespace, decimal integers, canonical enum names, strict duplicate/unknown-field rejection, bounded record-family sizes, and an outer SHA-256 corruption digest. R2 relies additionally on private namespace/IAM and provider encryption; the digest is not described as tamper authentication. | +| Record sizing | Operation/reference/session records are at most 64 KiB; terminal receipts at most 16 KiB; multipart part receipts are separate immutable records of at most 4 KiB each. A 10,000-part ledger is never materialized into one control object. | +| Conditional CAS | S3 uses `PutObject` `If-None-Match: *` for reserve and exact private ETag `If-Match` for revision CAS. The pinned SDK API must be characterized before use. MinIO must prove the same semantics in a non-skipping integration test. Filesystem local-dev uses process lock plus exclusive create/atomic replace and therefore stays R1. | +| Public reference | `osr1.<route>.<object>.<check>` where route is 12 lowercase Crockford Base32 characters, object is 26 lowercase Crockford Base32 characters (128 random bits), and check is the first 10 lowercase hex characters of SHA-256 over the first three components. Total parsing is bounded; the value contains no provider locator and is not authorization. | +| Stage/session handles | Separate prefixes (`osh1`, `osu1`, `osm1`) and the same bounded route/random/check structure. A stage or session handle is rejected by published-reference parsers and public read ports. | +| Operation deadline | Reuse `dev.caskeleton.application.outbound.CallBudget` as the absolute monotonic parent budget. Add a framework-free `CancellationView`; never serialize either value into durable control records. Persist only wall-clock attempt/lease timestamps and bounded policy durations. | +| Async S3 HTTP | Use `S3AsyncClient` with an explicitly configured `NettyNioAsyncHttpClient`. Do not use CRT, `S3TransferManager`, or SDK-owned automatic multipart for an R2 card. | +| AWS SDK | Keep the repository SSOT `awsSdkVersion = 2.30.0` for this plan. Characterize checksum defaults, conditional builders, and the `mpuObjectSize(Integer)` boundary. A version upgrade needs its own dependency/evidence decision. | +| Local-dev root | No code default. Unit tests use `@TempDir`; the explicit sample-local profile may bind `./.data/object-storage-v1`. Production profiles reject `filesystem-local-dev`. | +| MinIO identity | Initial test identity is `s3-compatible-minio-community-release-2024-01-16t16-07-38z`, corresponding to the existing `minio/minio:RELEASE.2024-01-16T16-07-38Z`. Phase 3 acceptance requires conversion to an image digest pin and records that digest as provider-version evidence. | +| Provider IDs | Only `filesystem-local-dev`, `aws-s3-general-purpose`, and the exact MinIO identity above are implemented in this plan. `filesystem-local-persistent` remains a follow-up provider. | +| Binding prefix | Canonical prefix is `app.object-storage`; `enabled` defaults to `false`, and there is no default provider or destination. Any simultaneous `ca-skeleton.objectstorage.*` and canonical configuration fails startup without logging values. | +| Composition SPI | Task 9 creates a side-effect-free provider-contribution registry. Settings are fully compiled before the assembler asks only selected contributions to construct clients. Normal semantic routers, scan-maintenance routers, and privileged purge routers are distinct concrete types/configurations; no catch-all router exposes a privileged port in a normal application context. Every later provider slice updates its explicit contribution and selected/unselected/disabled composition test—component scanning is not provider activation. | +| Bootstrap edge | Do not add an `app-bootstrap -> adapter-outbound-objectstorage` edge in this plan: there is no production use-case owner there. The sample already has the registered runtime-only edge. A future production owner requires a separate registry/Gradle approval. | +| Scanner owner | Application contracts and staged scan fencing are implemented; tests use a fake scanner verdict source. Selecting and implementing a production scanner is an **approval gate** and is required before the quarantine-publication card can claim R2. | +| Sample durable work | Use a dedicated `poster_image_upload_intent` table/repository and reconciliation use case. Do not reuse broker-delivery outbox rows as an object-storage operation journal. Object bytes never enter that table. | +| API compatibility | Preserve the existing `/posters/{id}/image` response during the legacy window. A new opaque-reference response and any upload-session endpoints require an **approval gate** plus intentional OpenAPI snapshot regeneration; no task silently removes `key`/`location`. | +| Direct-card ceiling | This plan implements provider/session primitives but no approved public direct-upload/download/session endpoint. Therefore direct single, direct multipart, and direct-download cards remain at most R1/partial and Task 29 may not promote them to R2. A follow-up inbound authorization/rate-limit/API snapshot plan is required. | +| Readiness registry | Add `docs/registries/object-storage-readiness.yaml`, schema version 1, with exact `card_id`, provider type/version, destination profile, claimed level, evidence revision/expiry, required non-skipping Gradle tasks, and limitations. Runtime descriptors are derived from compiled binding plus live qualification; the registry is the CI claim manifest, not a substitute for probes. | +| Cleanup ownership | Maintenance lease is `(destination route, job id, owner token, monotonically increasing fence, expires-at)`.

uniqueness; +- a bounded, non-reversible idempotency-scope digest (not the raw header/principal) maps retries to + the committed operation, and the stored request fingerprint detects scope reuse with new intent; +- state/revision/fence CAS permits one winner; +- `SUPERSEDED` is a durable terminal intent state and requires a same-transaction exact + losing-reference retirement row when publication already occurred; +- intent survives Poster deletion long enough to reconcile/retire; +- no object payload or presigned URL column exists; +- replacement/delete work uses a separate durable `poster_image_retirement_intent` row and cannot + be inferred from a deleted Poster or overloaded upload intent. + +The V8 intent table must include stable operation identity/epoch/destination, request fingerprint, +bounded idempotency-scope digest, expected poster version, exact content identity/media type, state, +stage handle, handoff claim/fence/expiry, published reference/version, replaced reference, +retry/error timestamps, and optimistic revision. Index the unique scope, operation, worker claims, +and expiry. Avoid a cascading FK that deletes required cleanup evidence. + +Store idempotency lookup as `(hmac_key_version, digest)`, never raw scope or plain SHA-256. The +HMAC input is a frozen `poster-image-idempotency-scope-v1` domain separator followed by +length-prefixed UTF-8 fields for tenant presence/value, principal, use-case, and Idempotency-Key; +ambiguous concatenations and tenant A/B must produce different golden vectors. Load an operator-supplied, +permission-checked versioned key-ring file from +the typed `app.poster-image.idempotency.key-ring-path` setting; do not add it to root `src/.env` or +an app-bootstrap-only env registry. The canonical production profile requires a nonempty active +key. Retain old keys for at least the maximum intent/idempotency/reconciliation horizon and rotate +overlap-first. A DB-coordinated key-epoch row is locked in the same reservation transaction: all +pods must possess the DB-active key; a stale pod fails new admission, and activation changes only +after every pod has the new retained key. Reservation queries all retained-version digests before +inserting under the active version. Tests race old/new pods across activation and prove one intent, +same-scope lookup, and no key material disclosure.

A bounded polling +worker claims `PENDING` rows and renews the object handoff; the transactional outbox events are +versioned integration notifications, not the only wake-up or an object-operation journal. This +choice must be mirrored in the deep design before implementation. + +- [ ] **Step 2: Write the failing crash-gap matrix** + +Inject a process/application stop: + +- after intent commit before stage; +- after data mutation before stage receipt; +- after stage before claim; +- after claim before DB PENDING; +- after DB PENDING before finalize; +- after finalize response loss; +- after publish before DB READY; +- after DB READY before claim release; +- before and after the single TX1 commit that atomically covers generic idempotency claim, + UploadIntent create-or-read, and generic reservation completion. + +Retry/reconciler must reuse the stable operation, avoid producer replay after staged evidence exists, +attach only exact READY reference, and never delete merely because a row is absent. The +non-skipping PostgreSQL atomicity test must prove a kill/failure before commit leaves neither row, +while commit leaves both COMPLETED generic reservation and matching intent—never a durable generic +`IN_FLIGHT` row without an intent. It also races two same-scope transactions and proves the loser +replays/commits normally, and proves expired reclaim. + +A worker must not attempt to recreate request bytes for a `RESERVED` intent. If the process dies +after TX1 but before staging, a same-key/same-fingerprint HTTP retry supplies a fresh producer and +continues the same operation; without retry, bounded intent expiry may authorize abort/report, not +invent data or publish. Once exact staged evidence exists, retry skips producer invocation. + +- [ ] **Step 3: Write failing concurrency tests** + +Cover same idempotency key/same fingerprint, same key/different fingerprint, two replacement +operations against one expected Poster version, reserve-expiry versus late PENDING, abort +authorization versus finalize, and Poster deletion during replacement. Prove deterministic CAS +winners. If finalize already published before the Poster CAS loses, commit `SUPERSEDED` plus a +dedicated exact losing-reference/version retirement row in the same transaction; a thrown/rolled +back CAS path is forbidden. Prove that row survives deletion, worker takeover, response loss, and +process restart. Prove the versioned +ready event exposes an opaque reference rather than a raw key. The old +`poster.image-attached`/`imageKey` contract is unchanged; the Gate A choice controls a new event +type/envelope or bounded dual publish, with checked-in consumer inventory and rollback evidence. + +Freeze `poster-image-publication-fingerprint-v1` as length-prefixed canonical bytes over schema, +Poster ID, expected Poster version, destination/profile, normalized media type, exact declared +length, and caller-supplied full-file SHA-256. Exclude multipart boundary, part/header ordering, +filename, and transport framing. Golden vectors prove two encodings of the same multipart semantics +match, while any semantic field change conflicts. The factory runs before TX1 without consuming the +file stream; staging recomputes byte count/SHA-256 and rejects a mismatch. + +- [ ] **Step 4: Verify RED** + +Run: + +```bash +cd src +./gradlew :adapter:outbound:persistence-jpa:test \ + --tests '*IdempotencyStoreAdapterTest' \ + --tests '*PostgreSqlIdempotencyClaimRepositoryTest' --console=plain +./gradlew :sample-portfolio:test \ + --tests '*PosterImagePublicationPolicyTest' \ + --tests '*PosterImagePublicationFingerprintTest' \ + --tests '*PosterImagePublicationEventContractTest' \ + --tests '*PosterImageObjectStorageConfigTest' \ + --tests '*PosterImagePublicationWorkflowTest' \ + --tests '*PosterImagePublicationCrashMatrixTest' \ + --tests '*PosterImagePublicationConcurrencyTest' --console=plain +./gradlew :sample-portfolio:posterImageMigrationTest \ + --tests '*PosterImageReservationAtomicityQualificationTest' --console=plain +``` + +Expected: new recoverable reservation/publication symbols are absent. The existing legacy +`UploadPosterImageCommand`, `UploadPosterImageUseCase`, controller, response, and wire test remain +unchanged and must still compile/pass in this task. + +- [ ] **Step 5: Implement the minimum workflow** + +The new `PublishPosterImageCommand` may carry the framework-free `ObjectContentProducer`, exact +content identity, media type, `CallBudget`, cancellation, and `IdempotencyContext`; it must not carry +`MultipartFile` or another inbound type. Keep the legacy command/use case intact until Task 23. +`PublishPosterImageUseCase` is `Idempotency.KEYED`, but the generic executor wraps only TX1 +create-or-read reservation and immediately stores the bounded stable operation/intent result. +Build `RequestFingerprint` only from the canonical semantic fingerprint above, never raw multipart +bytes/boundary. +The exact shape is +`tx.inWrite(() -> idempotencyExecutor.execute(sanitizedContext, createOrReadIntent, +reservationCodec))`; +the existing JPA idempotency store participates in that caller transaction, and the reservation is +small enough to stay inline. Thus generic claim, durable intent, and generic COMPLETED response +commit or roll back together. The POST-facing use case always returns that same `202` reservation; +it never mixes a later READY payload into the generic replay record. In that same HTTP invocation, +after TX1 commits, consume the request-bound producer to stage/verify outside TX, acquire handoff, +and commit TX2 PENDING; only then return the stable reservation. Finalize/TX3 READY is keyed by the +operation and owned by the bounded intent worker. The authorized status query reads the intent and +returns a locator-free progress/result view. No remote I/O or producer invocation occurs in TX1, +and no worker reads a request producer after the response. Allocate the operation ID only in the +committed intent and reuse it after generic replay/expiry. Application policy owns Poster +media/size, permission, and idempotency semantics; transport and destination policies do not, and +this sample does not invent resource ownership. + +Before relying on the outer transaction, add a vendor-neutral `IdempotencyClaimRepository` SPI and +implement this exact statement only in the allowed `.postgresql` package: +`INSERT ... ON CONFLICT ON CONSTRAINT uq_idempotency_scope DO UPDATE SET +id=EXCLUDED.id, request_hash=EXCLUDED.request_hash, status='IN_FLIGHT', +response_payload=NULL, response_ref=NULL, created_at=EXCLUDED.created_at, +expires_at=EXCLUDED.expires_at WHERE idempotency_record.expires_at <= :now RETURNING id`. +One returned ID means a new/expired claim won; no row means a live winner exists. A uniqueness +exception must never poison the caller transaction. + +Because executor `find` can load an expired entity before native reclaim, detach only that exact +expired `IdempotencyRecordEntity` before the claim and reload the returned ID/fingerprint before +complete; never call `EntityManager.clear()` or detach unrelated business entities. The +sample/PostgreSQL configs explicitly select this implementation; no vendor SQL enters the generic +idempotency package. Preserve the existing application port contract and prove winner/loser, +expired-find→reclaim→complete with new fingerprint/expiry/COMPLETED state, and unrelated managed +entity preservation in non-skipping real PostgreSQL. Do not emulate with a process lock. Update the +owner README/CLAUDE vendor SPI table. The same qualification queries both `idempotency_record` and +V8 intent tables and proves neither contains the raw Idempotency-Key, tenant, or principal; stored +aliases/digests retain tenant separation. + +Reconciliation settings are constructor-bound, disabled by default, and bound batch size, +claim/renew duration, fixed delay, retry/backoff, concurrency, and shutdown grace.

Prove same-transaction enqueue +for TX3 winner's replaced reference, TX3 loser's already-published `SUPERSEDED` reference, and +business delete; independent claim/lease/fence/retry after the Poster row is gone; two-worker CAS; +process death during retirement; lost retirement response resolved by exact reference/version +inspect; and durable terminal/held evidence.

Apply mode requires an +explicit reviewed manifest of candidates and per-row CAS. Flyway never performs backfill. Keep old +route/binding readers and legacy objects until observation proves zero legacy reads and all +missing/corrupt cases are resolved. The application contract for this operation remains in the +deprecated legacy migration namespace and may be injected only into the named administrative +adoption use case; no normal business endpoint may use it. `LegacyObjectLocator` is capped at 1,024 +UTF-8 bytes, rejects controls, redacts `toString`/errors, never appears in adoption receipts, and is +the exact architecture-tested exception to the new semantic no-locator rule. + +The adoption use case lives in the allowlisted `..poster.migration..` package, requires the exact +administrative permission, and is assembled only in an explicit maintenance profile. Settings bind +report path, reviewed-manifest path/digest, batch size, deadline, and mode; default is disabled and +`REPORT_ONLY`. `APPLY` additionally requires a detached, canonical +`LegacyObjectAdoptionApproval` document. Its JDK-only length-prefixed codec binds the approval +schema version, adoption operation ID, exact reviewed-manifest SHA-256, legacy namespace digest, +target destination/namespace, literal mode `APPLY`, `notBefore`, expiry, nonce, and two distinct +approver key IDs. Both approvers independently sign those exact canonical bytes with Ed25519. +Trusted public keys come only from permission-checked configured files; inline or manifest-supplied +keys are rejected. The verifier checks canonical re-encoding, both signatures, distinct trusted +approvers, every binding, time window, and bounded manifest bytes before any mutation. + +After verification, a durable replay record CAS-binds the nonce to the same operation, manifest, +namespace pair, and approval digest. A terminal replay of that exact operation is idempotent; +reuse for any other operation or digest fails closed. `LegacyPosterImageAdoptionAuthorizationPolicy` +then requires the isolated maintenance execution identity, exact administrative capability, and +verified approval receipt before invoking the adoption port. The maintenance runner supplies that +identity explicitly; it neither depends on a web `SecurityContext` nor treats +`@RequiresPermission` as scheduler authorization. Call order is: + +```text +load bounded reviewed manifest and signed approval +-> verify canonical bytes, two signatures, bindings, time window, and execution identity +-> claim/replay-CAS nonce for the exact adoption operation +-> re-read and re-hash the immutable manifest +-> per-row inspect/digest and CAS adoption +-> mark exact replay record terminal with evidence +``` + +Tests fail closed for absent or malformed approval, forged signature, one signer, the same signer +twice, untrusted key, wrong operation/manifest/legacy namespace/target namespace/mode, expired or +not-yet-valid approval, nonce replay against a different binding, changed manifest bytes, missing +or mismatched maintenance identity, and normal-context invocation. `REPORT_ONLY` does not require +an APPLY approval and cannot enter the mutating path. The normal web/application context exposes +neither the raw-locator port nor an adoption entrypoint. + +Neither the adapter adoption service nor the sample adoption use case/job uses a component +stereotype. Explicit maintenance configurations assemble them only after mode/profile, reviewed +digest, signed-approval trust store, permission boundary, maintenance identity, and isolated +legacy/new namespaces validate; normal and canonical publication contexts assert zero +migration-port/verifier/replay-store/runner beans and zero side effects. The closed control codec +registers approval replay records with golden/new-reader/old-reader compatibility fixtures. + +Retirement settings are constructor-bound and disabled by default, with bounded claim/renew, +batch/page, delay, retry/backoff, concurrency, and shutdown grace. The job claims the dedicated V8 +retirement table and calls only logical exact-reference retirement outside DB transactions. A +disabled context creates no scheduler/thread; stale fence/takeover is rejected and response loss +remains operation-keyed exact-reference/version reconciliation, not blind retry. TX3 replacement and +`DeletePosterUseCase` insert the row in the same DB transaction; its FK/retention preserves work +after Poster deletion. Physical purge remains separately privileged in Tasks 26–29. + +All three named use cases implement the repository `CommandUseCase` convention with explicit +commands/results and `@UseCaseCapability`; jobs invoke those boundaries rather than calling a +repository/port directly. Adoption carries the admin-only legacy exception, while logical +retirement/reconciliation use only opaque exact references. + +- [ ] **Step 5: Run Batch E checkpoint** + +Run: + +```bash +cd src +./gradlew \ + :application-core:check \ + :adapter:outbound:persistence-jpa:check \ + :adapter:outbound:objectstorage:check \ + :sample-portfolio:check --console=plain +./gradlew :sample-portfolio:posterImageMigrationTest --console=plain +./gradlew :app-bootstrap:test --tests '*CleanArchitectureTest' --console=plain +./gradlew verifyCleanArchitectureDependencies verifyPublicPathSnapshot --console=plain +``` + +Expected: PASS.

Any repository-root `.git` filesystem entry is detected +without following symbolic links, so a directory, worktree metadata file, or dangling symlink always +selects the checkout branch. Both Git processes must start, exit zero, and return valid evidence +before `CLEAN` or `DIRTY` can be emitted. `ATTESTED` is reserved for a truly absent `.git` entry in +an explicitly Git-less build with an exact supplied revision; a Git execution failure must never +fall back to it. + +- [ ] **Step 6: Verify GREEN without `.git` and verify evidence mismatch failure** + +Run the focused contract test, `./gradlew help` in the Git-less fixture with a 40-character +`gitRevision`, and one Redis evidence task in the real checkout.

The six canonical manifests contain 265 ACL command +occurrences and exactly 37 unique commands; `aclCommands.items` now uses that exact enum so adding +a command requires an explicit schema change.

Active, +missing, template, and newly introduced stub drift now fail the same exact-set contract. Messages +and the runbook template forbid adding new legacy allowlist entries and direct maintainers to +complete the runbook or adopt the future governed ledger. + +The focused RED failed only because `migration-failed.md` was an unexpected legacy-debt element. +After the containment change, the focused Runbook contract passed with 6 tests, zero failures, and +zero skips. Fresh verification also passed `:app-bootstrap:spotlessJavaCheck` and +`:app-bootstrap:check` (77 tasks; 18 executed, 59 up-to-date). Owner, issue, start/sunset, +expiry enforcement, and the private-wiki provenance migration remain deliberately incomplete and +the corresponding Batch 5 checkboxes remain open. + +### Batch 5-B/C unresolved semantic migrations audit (2026-08-02) + +These items are intentionally not marked complete.

There is no tracked selector +catalog, no Gradle declaration containing those IDs, and no ID that can currently be proven to +resolve to one exact module/task/class/method selector. Exact Java test-source literals cover only +17 IDs (45 occurrences, 40 in comments/Javadocs); 199 IDs have no exact source literal. Creating +216 selectors from namespaces or historical branch labels would manufacture execution evidence, +so the exact-linkage gate requires semantic owner confirmation or new tests before it can be +enabled. + +The runbook corpus contains 43 stub documents, all with response owner `oncall` but no accountable +debt owner, real issue, approved expiry, or bounded debt window. The seven legacy registries contain +30 distinct `owner_branch` labels, none resolving to a current local/remote Git ref, while their +private-wiki paths are absent from a fresh clone. The repository files are now protected as the +tracked artifacts, but current owner IDs, historical-label migration, CODEOWNERS identities, +runbook expiry dates, the `INTERNAL_ERROR` reverse-link decision, and the four umbrella-runbook +retention decisions require real project-owner input.

The full +`DeveloperExperienceContractTest` and `ConditionalTransportQualificationContractTest` classes +passed, `posterImageMigrationTest` produced 4 tests with zero skips, and both the 27-entry gate +validator and Gradle wrapper verifier passed. The complete sorted six-workflow SHA-256 lock was +refreshed after review; app-bootstrap Java and sample-portfolio Spotless checks also passed. An +independent Batch 6 link/Poster read-only review found no Critical, Important, or Minor issues. + +Batch 6 HTTP evidence: the focused synchronization contract first failed on exactly five fixed +sleeps across `OutboundHttpClientTest` (one), `OutboundHttpClientDeadlineTest` (one), and +`OutboundCallExecutorTest` (three). The HTTP handlers now signal `requestStarted`, await a bounded +`releaseResponse` latch, and are released in the caller's `finally` after the timeout result and +classification assertions. Executor workers now block on a bounded latch interruption point, with +the existing started/interrupted evidence and caller cleanup preserved. The four focused classes +passed 25 tests with zero failures, errors, or skips. A 3-second read-timeout mutation failed when +the handler's 1-second HTTP 204 fallback completed successfully, proving that the test cannot pass +via the separate 5-second logical deadline. The full owner `test` passed, and +`:adapter:outbound:httpclient:check` passed 29 tasks (16 executed, 13 up-to-date), including +Spotless, Checkstyle, SpotBugs, architecture dependencies, and environment-key verification. No +production source changed. Independent re-review found no remaining Critical, Important, or Minor +issues and found no cleanup leak or deadlock race. + +Batch 6 sample-off evidence: the focused build contract first failed because the dedicated source +directory, compile lifecycle task, strict registration, and required FQCN did not exist. The +`sampleOffTest` source set now compiles all 204 ordinary test sources plus the dedicated contract +without `sample-portfolio`, while `sampleOffCompile` exposes that complete compile proof separately. +The externally stable `sampleOffTest` task is registered through the shared strict qualification +convention and executes only `SampleOffClasspathContractTest`; fresh XML reported exactly 1 test, +0 skipped, 0 failures, and 0 errors. The existing eight strict-convention functional contracts +passed, including missing-class, no-discovery, skip, and stale-evidence fail-closed cases. The +focused build contract, `sampleOffCompile`, gate-matrix validator, wrapper verifier, dependency-lock +verification, Spotless, and the full `:app-bootstrap:check` also passed; the full check completed 78 +tasks (23 executed, 55 up-to-date). This is focused/owner evidence; the repository-wide Batch 6 +aggregate is recorded below. + +Batch 6 repository evidence (2026-08-02): the real gate-matrix validator passed all 27 entries +(26 locally verified and the protected AWS lane explicitly delegated-pending), the Gradle-wrapper +contract passed, `bash -n .github/scripts/verify-gate-matrix.sh` passed, all eight tracked registry +YAML documents parsed, the Redis Draft 2020-12 schema parsed as JSON, and `git diff --check` +reported no whitespace errors. The first repository `check` exposed a 503 in the first +`JwtJwksSecurityFilterIntegrationTest` request while static-analysis workers were running. The +single test passed in isolation, identifying a test-fixture scheduling race rather than a JWT +classification mismatch. The embedded OIDC server now owns a dedicated single daemon executor and +shuts it down in `close()`; the full eight-test security-boundary lane plus Checkstyle and Spotless +passed, and a fresh repository `check` subsequently passed with the same boundary lane included. + +## Final verification and capture + +- [x] Run full Gradle tests/checks and all repository validators. +- [x] Request an independent P2 code review, resolve actionable findings, and record semantic + blockers separately. +- [x] Update the LLM Wiki branch note and any honest derived raw documents. + +Fresh aggregate evidence (2026-08-02): + +- `./gradlew test --no-daemon --console=plain` — successful in 4m 24s (86 tasks). +- `./gradlew check --no-daemon --console=plain` — first run failed only on the OIDC test-fixture + race above; after the bounded fixture correction, successful in 4m 35s (260 tasks). +- Final post-review `./gradlew check --no-daemon --console=plain` — successful in 10m 33s + (260 tasks; 76 executed, 184 up-to-date).

It links bidirectionally to one resolved error note, one interview-prep note, and one +blog-topic note. The vault's targeted structure lint passed all three derived documents. The branch +note passed its content, frontmatter, required-section, and wikilink checks but retained one explicit +`NAMING_VIOLATION`: repository policy requires `<branch-name>.md` (`main.md`) while the vault naming +rule permits only `feature|fix|chore|experiment-` branch-note prefixes. Neither policy was silently +weakened; the exact conflict is the recorded capture-validation blocker. + +Independent aggregate review evidence (2026-08-02): the first pass reported zero critical, +three important, and two minor findings. Wiki capture closed the capture-pending finding; the two +remaining important items were reclassified as the three project-semantic blockers already kept +open in Batch 5. The two minor code findings were corrected with an exact test-fixture-only +GraphQL SpotBugs exclusion and registry-derived scanning of all 18 production leaves in +`SampleRemovalSmokeContractTest`. A follow-up audit also found and removed the last tracked-file +assumption/upward-directory search in `PortfolioErrorCodeRegistryMappingTest`, replacing it with a +canonical repository-root property, relative Gradle input, and missing-root/symlink-escape +fail-closed checks. The re-review found no new code defect; its only completion-evidence concern +was a stale SampleRemoval XML, addressed by the final repository `check` after these corrections. +The reviewer retained only the Wiki naming-policy disclosure and this Batch 5 checkbox wording as +minor documentation findings; both are now explicit here and in the branch note. diff --git a/docs/superpowers/plans/2026-08-02-redis-session-http-boundary.md b/docs/superpowers/plans/2026-08-02-redis-session-http-boundary.md new file mode 100644 index 0000000..b3e11cb --- /dev/null +++ b/docs/superpowers/plans/2026-08-02-redis-session-http-boundary.md @@ -0,0 +1,72 @@ +# Redis Session HTTP Boundary Implementation Plan + +> **Execution:** Follow test-driven development and request an independent read-only review before +> advancing to the remaining P1 work. + +**Goal:** Prove browser-session security persists and fails closed across the real Spring Session ↔ +Redis composition, without silent skips. + +**Architecture:** The app-bootstrap composition test reuses its existing Redis test source set and +dependencies.

Why the structure differs from the plan + +The design and plan were written without the target repository attached, so they assume a +`backend-skeleton/` root with twelve standalone Gradle projects under `modules/redis/`, Kotlin DSL +build files, and the `io.backend.skeleton.redis` package root. The package README anticipates exactly +this and instructs the implementer to keep the structural contract while conforming to whatever +stronger rules the real repository already enforces. + +This repository has three such rules, and all of them outrank the plan's file layout: + +1. `src/config/architecture/modules.json` is a fail-closed registry of **exactly 19 leaf modules**, + re-validated by `src/settings.gradle` on every configuration. Adding twelve Gradle projects would + violate HARD-STOP condition 5 in `AGENTS.md`. +2. The build is Groovy DSL with `dependencyLocking(STRICT)`, so the plan's `libs.versions.toml` + entries and its Spring Data Redis 4.1 / Lettuce 7.6 pins cannot be introduced without regenerating + lock state. The repository is on Spring Boot 4.0.0 with **Lettuce 6.8.1**. +3. The package root is `dev.caskeleton`, not `io.backend.skeleton`. + +The SDK therefore lives inside the already-registered `adapter:outbound:cache-redis` leaf, and each +designed module is a package. What the separate Gradle projects would have enforced — +dependency direction and driver containment — is enforced instead by +`RedisSdkModuleBoundaryTest`, which reads the source tree and fails on a forbidden import. + +### Module mapping + +| Design module | Package under `dev.caskeleton.adapter.outbound.cache.redis.sdk` | +| --- | --- | +| `redis-core-api` | `api`, `api.key`, `api.codec`, `api.command`, `api.error`, `api.operations`, `api.reactive` | +| `redis-core-lettuce` | `lettuce.codec`, `lettuce.command`, `lettuce.connection`, `lettuce.observability` | +| `redis-spring-boot-starter` | `config` | +| `redis-cluster` | `cluster` | +| `redis-programmability` | `programmability` | +| `redis-raw-gateway` | `raw` | +| `redis-admin-plane` | `admin` | +| `extensions/*` | `extensions.json`, `extensions.search`, `extensions.timeseries`, `extensions.probabilistic` | +| `redis-testkit` | `src/test` and the existing `redisTest` source set | + +### Other adaptations, and the reason for each + +| Plan says | Repository does | Why | +| --- | --- | --- | +| `backend.redis.*` properties | `ca-skeleton.capabilities.redis-sdk.*` | Matches the existing capability property namespace and avoids colliding with `app.cache.redis`. | +| `RedisEnvelope` is a record with a `byte[]` component | Value class with the same accessors | ErrorProne `ArrayRecordComponent` is a blocking check in this build. | +| Jackson-based YAML policy loader | Explicit strict reader for a closed YAML subset | No Jackson or SnakeYAML on the main compile classpath, and a general YAML engine would accept anchors, merges, and duplicate keys inside a security policy file. | +| `VersionedJsonCodec` maps objects reflectively | Frames a versioned JSON envelope around a caller-supplied `RedisPayloadCodec` | Same guarantee — schema id, version, size ceiling, hard failure on an unknown version — without an object mapper the module cannot depend on. | +| Each task ends with `git commit` | No commits | `AGENTS.md` commit policy is `human-only`. | +| Gradle tasks `redis72Test` … `cluster82Test` | Not registered | They belong to Task 8's testkit half and Task 26; both need Docker-backed Testcontainers, which Milestone A does not reach. | + +--- + +## 2.

What Milestone A actually guarantees + +- Every command the SDK will ever run is classified in + `src/main/resources/redis-sdk/redis-command-policy.yml`. An unclassified command is refused by + `RedisCommandCatalog`, so a Redis upgrade cannot make a new command reachable by default. +- `KEYS`, `FLUSHALL`, `FLUSHDB`, `SHUTDOWN`, `DEBUG`, `EVAL`, `CONFIG SET`, and the deprecated + command names are `BLOCKED` with ACL account `NONE`. +- R2 commands cannot execute without both an issued permit and an `OperationBudget`, and a permit the + caller implemented itself fails provenance verification. +- Sync and reactive typed API surfaces are mechanically proven to be in parity. +- Metric and trace tags are a closed low-cardinality set with no key, field, member, or value in it. +- A write that timed out is reported as `RedisAmbiguousExecutionException` with `retryable=false`, + and `RedisFailureMetadata` rejects the retryable-and-ambiguous combination at construction. + +## 4. What Milestone A does not guarantee + +- No command has been executed against a real Redis server by this work. Every test is a unit or + contract test over fakes; the contract suites the plan defines for Tasks 10–17 do not exist yet. +- The typed operation interfaces have no implementation, so `RedisOperations` cannot be wired into a + Spring context yet. `RedisSdkSettings` is bound but no bean registration reads it. +- Cluster slot calculation is a caller-supplied function; the CRC16 implementation is Task 19. +## 5. Cleanup of everything the design does not specify + +The leaf previously carried five Redis capabilities that this design does not describe — semantic +cache, session, request-replay idempotency, soft lease, and edge rate limit — together with their +evidence and readiness governance. All of it is removed, so the Redis surface is now exactly the +SDK. + +| Removed | Scale | +| --- | --- | +| `cache-redis` non-SDK sources, tests, Lua programs, and the `redisTest` evidence source set | 188 main + 105 test + 18 evidence Java files, 52 resources | +| `cache-redis/build.gradle` | 626 lines → 22; ~50 evidence/readiness lanes gone | +| `app-bootstrap` Redis wiring, health contributor, material providers, `redisCompositionTest` source set | 15 files plus its Gradle tasks and configurations | +| `application-core/src/redisPolicyContractTest` | 1 file plus its source set | +| Root `build.gradle` Redis readiness/evidence/CI-matrix governance | 1,420 lines | +| `config/redis/`, `gradle/redis-test-images.properties`, `infra/redis-lab/`, `.github/workflows/redis-production-readiness.yml` | removed | +| `ci-quality-gates.yml` / `ci-gate-matrix.yml` | `redis-standalone` job retargeted to `redis-sdk` | + +Kept deliberately: `shared-contract`'s `EdgeRateLimitPort` and its provider-neutral contract test. +It is a rate-limit port, not a Redis type, and the design's exclusion list covers business policy +rather than application ports. + +Verified after the cleanup: `./gradlew test`, `verifyCleanArchitectureDependencies`, +`verifyEnvKeys`, `verifyDependencyLocks` all pass; `verify-gate-matrix.sh` reports 27 gates OK. +Dependency locks were regenerated for every module. + +## 6. Task 10 — decisions a reviewer should check + +The string and key/TTL operations landed in `sdk.lettuce.operations`, which is the package form of +the plan's `redis-core-lettuce/.../lettuce/operations`. Five things differ from a literal reading of +the plan, each for a stated reason. + +| Decision | Why | +| --- | --- | +| A narrow `RedisCommandGateway` seam sits between the typed operations and Lettuce; `LettuceRedisCommandGateway` is the only class that touches the driver. | The plan's contract suites run on Testcontainers, which this environment has no lane for. The seam lets the whole policy path — catalog, permit provenance, budget, admission order, decode — be proven deterministically, and it keeps driver containment real rather than asserted. It is not a substitute for the real-server evidence Task 26 owns. | +| Where design section 10 gives an R2 method only a permit (`multiGet`, `delete`, `unlink`, `rename`, `scan`) or only a budget (`append`, `getRange`, `setRange`), the SDK fills the missing half. | `CommandPolicyGuard` requires both for every R2 command. The caller-supplied half always wins; the other comes from `RedisOperationLimits` or a permit the SDK itself holds. Without this, half the designed R2 surface could not be admitted at all. | +| Increment-with-initial-TTL runs a registered Lua script, and the SDK loads that script itself inside the guarded `EVALSHA` invocation. | Redis 7.2–8.2 has no `INCR` variant carrying an expiry, and both two-command sequences leak a permanent counter on a crash. The `SCRIPT LOAD` that resolves the digest is therefore *not* separately admitted by the guard — it travels under the `EVALSHA` admission with the same `registered-script` permit and script budget. Proper script registration is Task 20/21's `programmability` module; this is the narrowest thing that makes the operation correct in the meantime. | +| No `INCREX` version-gated path. | No shipped Redis version has the command, so it is in neither the policy catalog nor `RedisCapability`. Adding a gate for a command that does not exist would be untestable. | +| `expire`/`expireAt` report `ABSENT` only when the condition was `ALWAYS`. | Redis answers `0` both for a missing key and for an unmet condition. With `ALWAYS` the only possible cause is a missing key; with any other condition the SDK reports `CONDITION_NOT_MET` rather than guessing. A non-positive TTL is refused outright instead of silently deleting the key. | + +Coverage: 30 new tests (`RedisValueOperationsContractTest`, `RedisKeyOperationsContractTest`) over +permit provenance, budget ceilings, atomic counter creation, script reload after `NOSCRIPT`, +namespace-bounded paging, and blocking/reactive agreement. `lettuce/operations` is registered in +`RedisSdkModuleBoundaryTest.DESIGNED_MODULES`. + +## 7. Task 11 — the field-TTL version gate + +The gate design section 10.2 asks for is applied in two independent places, because either one alone +is weaker than it looks. + +- `LettuceRedisHashFieldExpirationOperations.ifSupported(...)` returns empty below Redis 7.4, so a + composition root has nothing to inject and a caller cannot hold the API at all. This is the + "bean is absent on 7.2" property the plan's Redis 7.2 test asserts. +- `HEXPIRE`, `HPEXPIRE`, `HPERSIST`, `HTTL`, and `HPTTL` carry `minimum-version: "7.4"` in the policy + catalog, so `CommandPolicyGuard` refuses them on an older server even for a hand-built instance. + `guardRefusesFieldExpiryOnAnOlderServer` proves that second layer by forcing an instance into + existence against a 7.2 server and watching the guard reject it. + +`entries` is R2 with a caller-supplied permit *and* budget, exactly as designed — it is the one hash +method the design gives both, so nothing is filled in for it. `HSCAN` gets the Task 10 treatment: an +SDK `cursor-scan` permit and a budget derived from the requested page, because +`scan(HashKey, ScanRequest)` carries neither. `HGETALL` and `HSCAN` replies are measured against the +budget before decoding, so an oversized hash is refused rather than materialised. + +One Lettuce accommodation is worth knowing about: its only batched `HSET` takes a `Map`, which for a +`byte[]`-keyed connection means identity hashing. The seam therefore passes two positional lists and +`LettuceRedisCommandGateway.hashPutAll` is the single place that builds the map — never reading from +it, only iterating — with the ErrorProne check suppressed there and nowhere else. + +## 8. Task 12 — the range commands are encoded, not borrowed + +Design section 10.5 requires `rangeByScore`, `rangeByLex`, and a descending `rangeByRank`. Lettuce +6.8 has no typed `ZRANGE ... BYSCORE / BYLEX / REV`; its only typed paths are the deprecated +`ZRANGEBYSCORE`, `ZREVRANGEBYSCORE`, `ZRANGEBYLEX`, `ZREVRANGEBYLEX`, and `ZREVRANGE`. + +Those five stay `BLOCKED`, exactly like `SETNX`, `GETSET`, `HMSET`, `RPOPLPUSH`, and `GEORADIUS`. +`LettuceRedisCommandGateway` encodes the modern command itself — `ZRANGE key min max +BYSCORE|BYLEX [REV] LIMIT offset count [WITHSCORES]` — through Lettuce's typed `dispatch` with a +fixed `CommandType.ZRANGE`, a fixed output, and arguments built from the already-rendered key. Every +range read therefore declares `ZRANGE` to the guard and sends `ZRANGE` on the wire, so the ACL +account and the catalog drift gate stay aligned with reality. + +This is not the forbidden raw-command surface: there is no method anywhere that accepts a command +name, and the encoding lives in the one class that is already allowed to know the driver. + +Everything else in Task 12 follows Task 10's rules. `SMEMBERS` has no method at all — the API offers +`scan` or permit-and-budget set algebra, and a test asserts no whole-set reader exists. +`SRANDMEMBER`, `SSCAN`, and `ZSCAN` get an SDK permit plus a derived budget because their signatures +carry neither; `SMOVE` takes the caller's multi-key permit; `SDIFF`/`SINTER`/`SUNION` and every range +read take both from the caller, and the reply is measured against the budget before it is decoded. + +## 9. Task 13 — the blocking lane + +`LettuceRedisBlockingListOperations` takes its own `RedisCommandGateway`, which the composition root +binds to a connection borrowed from `RedisConnectionKind.BLOCKING`. That parameter is the structural +form of design section 10.3's "separate bean, dedicated pool": a command that occupies its +connection until the server answers cannot be issued down the lane ordinary traffic shares, and the +type system is what stops it rather than a convention. + +An unbounded wait is impossible on three independent levels: the request always declares its block, +`ListOperationRequests` refuses a non-positive one before building anything, and +`CommandPolicyGuard` refuses a block above the configured ceiling and sets the client timeout to the +block plus `TimeoutProfile.BLOCKING_MARGIN`. All three are asserted. + +`BLMOVE` needs both authorisations and the design gives the caller only one, so the caller's +multi-key permit is verified in the operations layer while the SDK supplies the `blocking-pop` +permit the guard demands. Crossing two keys and occupying a connection are separate decisions and +the caller must still hold the first. + +## 10. Task 14 — the ceiling that matters + +A single `SETBIT` at an arbitrary offset allocates the whole prefix, so an unchecked offset is a +memory-exhaustion primitive rather than a write. `RedisOperationLimits.maxBitmapOffset` bounds every +bit offset — `GETBIT`, `SETBIT`, and each `BITFIELD` subcommand — before a command is built, and a +negative offset is refused outright. + +`BITOP`, `PFCOUNT`, `PFMERGE`, and `GEOSEARCHSTORE` take the caller's multi-key permit; `BITCOUNT`, +`BITPOS`, `BITFIELD`, and `GEOSEARCH` take the caller's budget with an SDK permit. A geo search is +bounded three ways — its own `count`, the collection ceiling, and the caller's budget measured +against the reply before decoding. + +## 11. Task 15 — the two decisions the design left open + +`RedisBatch` exposes only `size()`, `keys()`, and `requestBytes()`, so it is opaque: nothing in the +public contract lets a caller put commands into one. The SDK therefore owns both the concrete batch +and the only way to fill it, and two questions had to be answered. + +**What the builder covers.** `LettuceRedisBatch.Builder` covers the string, key, and hash surfaces +rather than mirroring all ~80 typed methods. Those are what pipelining is actually used for, each +extra method is one delegating line onto the existing request factories, and widening it later is +mechanical rather than a redesign. A batch built anywhere else is refused. + +**Whether R2 commands may be batched.** They may, carrying their own permit and budget exactly as +they do alone. `BatchOptions` has no permit field, so the alternative was an R1-only batch — which +would have blocked the case where saving a round trip matters most. Both ceilings apply and the +smaller wins: the guard refuses an item that broke its own budget before the batch ceiling is even +checked. + +Four properties are enforced rather than documented. Every item is admitted **before** any command +is sent, so one refused item cancels the batch instead of leaving it half-applied. Input index is +result index, failure or not. Items fail independently — `hasPartialFailure` is the caller's signal, +not an exception. And there is no retry path in the class at all, so a failed write is never +re-sent. + +## 12. Task 17 — a subscription is not a command + +Publishing goes through the guard like anything else. Subscribing does not: it has no reply to bound +and no timeout to apply, it occupies its connection for as long as it lives, and it therefore has +its own seam — `RedisPubSubGateway`, bound to a connection borrowed from +`RedisConnectionKind.PUBSUB`. A long-lived listener can never sit on the lane ordinary commands use. + +What the guard would have checked is checked in `PubSubOperationRequests` instead: every channel and +pattern must belong to the process namespace, an empty subscription is refused, and a pattern +subscription demands the `pattern-subscribe` permit because the server decides how much a pattern +matches. + +Lifecycle is the part that leaks if it is only documented. The blocking API returns an +`AutoCloseable` `Subscription`; the reactive API returns a `Flux` whose cancellation closes the +driver handle. Both are asserted against a bus that reports how many subscriptions are still open, +so an abandoned subscriber releasing its connection is a test, not a claim. + +Sharded Pub/Sub is gated exactly like per-field expiry: `ifSupported` yields nothing below Redis +7.0, and `SPUBLISH` carries the same minimum in the catalog so the guard refuses it independently. + +### Still outstanding + +`application.yml`, `.env`, and `docs/registries/env-keys.yaml` still carry the property blocks of +the five removed capabilities. They bind nothing and the build is green with them present, but they +are dead configuration and should go in the same sweep that removes the corresponding capability +sections. + +## 13. Task 16 — a stream entry, a payload field, and one command that had to be encoded + +**One payload field.** `StreamKey<V>` carries exactly one payload codec and `StreamRecord<V>` +exactly one value, so the SDK writes exactly one field, named `payload` in +`StreamOperationRequests` and nowhere else. An entry that comes back with any other shape is +refused rather than half-decoded: a foreign producer's record is an anomaly the caller has to see, +not something to silently truncate into a `StreamRecord`. + +**`XREAD` forced a catalog distinction.** `BLPOP` has no non-blocking form, so a request that omits +its block is a defect. `XREAD` does have one — the same command name is an ordinary bounded read +without `BLOCK`. The catalog previously modelled only "blocking", which would have meant either +rejecting every non-blocking stream read or excusing the stream reads from the rule that nothing +waits forever. Both were wrong, so `optional-block` was added to the policy schema and +`RedisCommandPolicy.requiresServerBlock()` now separates the two. `XREAD` and `XREADGROUP` are the +only commands that carry it. The blocking bean still takes a non-nullable `Duration`, and the guard +still refuses a non-positive block or one over the configured ceiling. + +**A group read has exactly two legal offsets.** `NewForGroup` and `PendingForConsumer` are accepted; +`After` and `Latest` are refused. Reading a group from an arbitrary identifier would hand a consumer +entries the group already distributed elsewhere without moving the pending list — a duplicate +delivery the caller did not ask for. The mirror rule holds for the group-free read, which refuses +the two group offsets. + +**`XAUTOCLAIM` is encoded, not borrowed.** Lettuce's typed `xautoclaim` returns `ClaimedMessages`, +which drops the third reply element: the identifiers that were pending but no longer exist in the +stream. `ClaimResult.deletedIds` is part of the SDK contract precisely because a consumer that +cannot see that list keeps sweeping the same tombstones forever. The command is therefore built in +`LettuceRedisCommandGateway` with `NestedMultiOutput`, the same precedent set by the sorted-set +ranges in §8 — the command declared to the guard is still the command on the wire, and no method +accepts a command name. + +**Permits and budgets.** `XTRIM` runs under `bounded-collection-write`, the ranges under +`bounded-collection-read`, both reads under the new `stream-read` policy, and `XPENDING`/`XAUTOCLAIM` +under `stream-recovery`. None of the design's stream signatures carry a caller permit, so all four +are SDK permits; the caller-supplied bound is the mandatory `count`, which becomes both the guard's +budget and the ceiling checked against `maxCollectionElements`. There is no "read the whole stream" +call that can be written against this API. + +**Redis 8.2 deletion landed; 8.8 `XNACK` did not.** `XACKDEL`/`XDELEX` are behind +`LettuceRedisStreamDeletionOperations.ifSupported(...)`, gated exactly like hash field expiry — the +capability probe decides whether a bean exists, and the catalog's 8.2 minimum refuses a hand-built +one. `XNACK` is deliberately not implemented: the pinned Lettuce 6.8.2 has no typed form for it, and +unlike `XAUTOCLAIM` its wire format cannot be verified against a driver or a released server, so +encoding it by hand would be inventing a protocol rather than adapting one. The capability, the +catalog entry, and the 8.8 minimum stay in place; the bean is the only missing piece and should be +added when the command is available in the driver or in a released server. + +## 14. Tasks 18–19 — the parts that do not need a cluster to be true + +Both tasks are specified against real Sentinel and Cluster environments, which this repository does +not yet have a lane for. What landed is the half that is decidable without one, and it is the half +the rest of the SDK depends on. + +**The slot calculator is a pre-flight check, not a redirect handler.** `RedisSlotCalculator` +computes CRC-16/XMODEM over the hash tag exactly as Redis does, so `CommandPolicyGuard` can refuse a +cross-slot multi-key command before it is written. A server-side `CROSSSLOT` would arrive after the +request left the process, which is precisely the outcome the guard exists to prevent. The seam was +already there — the guard has always taken a `ToIntFunction<String>` — so this task filled it rather +than changing the pipeline. The published slots for `foo`, `bar`, and `hello` are asserted, so a +regression in the checksum shows up as a wrong number rather than as a cluster that quietly +mis-routes. + +**An empty tag is not a tag.** `{}` hashes the whole key, matching Redis, and that is tested, +because the alternative — hashing an empty string — would collapse every such key onto one slot. + +**A cluster scan is not a snapshot, and `ClusterScanCursor` refuses to pretend otherwise.** A sweep +is complete only when every primary has *answered* with a zero cursor; a primary that was never +asked counts as unfinished. Reporting completion after skipping a shard would let a caller conclude +a key does not exist when a whole shard was never looked at. + +**Redirect counting separates two different incidents.** A trickle of `MOVED` means the client's +topology is stale; `ASK` and `TRYAGAIN` mean a resharding is in progress. The driver follows both +transparently, so neither is visible to a caller — `ClusterTopologyObserver` is what makes them +visible to an operator, and it accepts slot numbers and node identifiers only, never a key. + +**`ExecutionCertainty` is the failover decision made explicit.** "The server refused it" and "the +connection died after the command was written" look identical to a caller and have opposite +consequences. `SentinelFailoverObserver.classify` returns `SAFE_TO_RETRY_FAILURE` only when the +command provably never reached the server; anything written and unanswered is `AMBIGUOUS_FAILURE`, +and `allowsAutomaticRetry` then defers to the command policy's `retry-safe` flag. A non-idempotent +write is therefore never resent by the pipeline, and each one is counted so an operator knows how +many need reconciling. + +**The reconnect queue is bounded on purpose.** An unbounded queue turns a thirty-second promotion +into a thirty-second backlog that lands at once on a freshly promoted primary. Refusals past the +bound are counted so the bound can be tuned from evidence rather than guessed. + +**What is still owed:** the fault-injection evidence. Nothing here proves how Lettuce actually +behaves during a promotion or a resharding — that is a real-topology lane and belongs to Task 26. +These types are the classification and accounting that lane will assert against. + +## 15. Task 21 — scripts are a deployment artefact, and Task 20 is blocked on the fixture + +**Nothing accepts a script body at call time.** `EVAL` is blocked in the command policy, so the only +reachable path is `EVALSHA` of a digest that `RedisScriptRegistry` obtained from a `SCRIPT LOAD` of +a reviewed `RegisteredRedisScript`. A script assembled from request data has the blast radius of the +whole keyspace; making registration a deployment step is what turns "we only run reviewed scripts" +from a convention into a structural property. + +**Keys are declared, and that is what makes them checkable.** Every key goes into the request's key +list, so a script is namespace-checked and same-slot-checked exactly like any other multi-key +command. `RedisArgument` is a distinct type from a key for the same reason: a key smuggled through +`ARGV` would bypass both checks, and having the two be different types is what makes that a compile +problem rather than a review problem. + +**A registered script returns one bulk reply.** That is a contract, not a limitation of +`RedisResultDecoder`. A nested Lua table forces the SDK to guess how deep the reply is and how each +level is typed, which is the ambiguity a typed API exists to remove. Encode the result and decode it +in the decoder. + +**`NOSCRIPT` is the one automatic retry in the SDK.** The server rejects the call before running +anything, so reloading and re-issuing once repeats nothing. It is not a retry of an ambiguous write, +and no other failure is retried on this path. + +**Functions are callable, not loadable.** `FUNCTION LOAD` is `ADMIN_ONLY` in the catalog and belongs +to the admin plane, so `RedisFunctionOperations` has no method that introduces server-side code. +`RegisteredRedisFunction` carries the library's semantic version because a library replaced under +the same name changes behaviour with no signal at the call site. A function declared read-only is +issued as `FCALL_RO`, which lets the server refuse a wrong declaration — worth more than the replica +routing it also buys. + +**Task 20 is deliberately not half-done.** `WATCH`/`MULTI`/`EXEC` is implementable against Lettuce — +after `MULTI` the command futures complete when `EXEC` runs — but proving it needs a fixture that +models that deferral. The current `InMemoryRedisCommandGateway` completes every future eagerly, so a +transaction written against it would apply its writes *before* the `WATCH` conflict was detected: the +fixture would report a correct-looking conflict while the effects had already landed. A fake that +lies about atomicity is worse than no fake, so the transaction work is deferred until the fixture +grows a deferral model (or the real-server lane from Task 26 exists), rather than being landed +against a fixture that cannot falsify it. + +## 16. Task 22 — the escape hatch, and why it is not an escape + +The raw gateway exists because a few commands have no typed form worth building, not because +arbitrary command execution is acceptable. Everything about its shape follows from that. + +**Two independent gates, neither decided at request time.** A command must be classified +`RAW_ONLY` in `redis-command-policy.yml` — the organization's decision about which commands may ever +leave through this door — *and* the deployment must have registered an `ApprovedRawCommand` for it +in `RawCommandApprovals`. Neither alone is enough. The approval carries the argument, request, and +reply ceilings and the timeout, so widening what may be sent is a deployment change, not a call-site +one. + +**The token is bound to its registry.** `RawCommandApprovals.issue` is the only source, and +`verify` refuses a token from a different registry instance, a token issued for another policy, and +an approval that is not byte-for-byte the registered one. That last check is the one that matters: +without it a caller could present a widened copy of a real approval and keep the real policy id. + +**Keys are parsed back, not taken on trust.** Arguments reach the gateway as opaque bytes, so the +catalog's key specification locates the key positions and `RedisOperationContext.parseKey` — the +same strict parse `SCAN` uses — turns each one back into a `QualifiedRedisKey`. A key outside the +bound namespace or one that does not follow the key grammar is refused before anything is sent. A +`movable` key specification cannot be checked without asking the server with `COMMAND +GETKEYSANDFLAGS`, so it is refused at registration time; `SORT` and `SORT_RO` are therefore +classified `RAW_ONLY` but not approvable until that lookup exists. + +**Every RAW_ONLY command now names a permit policy.** The guard's rule is that an R2 command always +states the policy that authorised it. The raw path used to be the one place that rule did not hold, +so `raw-command` was added to the three `RAW_ONLY` entries and the gateway presents the SDK permit +for it. The approval registry still decides *which* commands a deployment may send; the permit is +what keeps the guard's invariant true on this path too. + +**Everything else was already built.** Reachability, minimum version, risk refusal, and the timeout +profile come from the catalog; namespace and same-slot from the guard; the audit record from the +executor's observation, which carries the command family and latency and never a key or a value. +The one new seam method, `sendApprovedRaw`, takes a `CommandId` rather than a string — by the time +it is reached the identity has already been validated, classified, and matched to an approval. + +## 17. Task 23 — the admin plane is defined by what it cannot do + +Design section 14.2 lists what the admin plane must never reach. None of it is enforced by +`RedisAdminOperations` omitting a method — omission is not enforcement, because the next person to +add one would not notice. `FLUSHDB`, `FLUSHALL`, `SHUTDOWN`, `DEBUG`, `CONFIG SET`, `CONFIG REWRITE`, +`CLIENT KILL`, `ACL SETUSER`, `ACL DELUSER`, `SLOWLOG RESET`, `LATENCY RESET`, `SCRIPT FLUSH`, +`FUNCTION FLUSH`, and `MODULE UNLOAD` are all `BLOCKED` in the catalog, which means no path in the +SDK can send them, and a test asserts that list rather than trusting it. + +**Every diagnostic is checked against the catalog before it is built.** Not classified +`ADMIN_ONLY`, or not read-only, and it is refused. That check is what stops a future addition to +this class from quietly becoming a write. + +**Replies are projected, not forwarded.** A slow log entry carries the command family and drops the +arguments; a client entry carries id, age, idle, and last command and drops the peer address and the +connection name. Both are read by an operator and end up in dashboards and tickets, and the dropped +fields are exactly the caller and tenant identity that must not travel that way. The command family +is enough to find a call site; an address is not needed to find a leaking pool. + +**A key is still a key.** `MEMORY USAGE` takes a `QualifiedRedisKey` and goes through the guard, so +an admin diagnostic cannot read a key outside the bound namespace. An absent key reports {@code -1}, +not zero, because "this key uses no memory" and "this key does not exist" are different answers. + +**Separation is structural, not documentary.** The plane takes its own gateway, bound to the admin +account's own connection, the same way the blocking operations take theirs. What that cannot enforce +is that the deployment actually configured a separate ACL account — which is precisely why the +dangerous commands are blocked catalog-wide rather than left to the credentials to prevent. + +## 18. Tasks 24–25 — four extensions, one seam, and the checks the guard cannot do + +All four extension families share `ExtensionCommandRunner`, so every extension command declares its +key and is namespace- and slot-checked exactly like a classic one. Sharing the runner is also what +stops them drifting apart on the parts that matter. + +**The probe is the authority, the version is a pre-filter.** A managed Redis 8 with no module loaded +reports the version and not the commands, so each bean is created through `ifSupported(...)` and a +deployment without the module simply has no instance. Catalog minimums are the second gate, not the +first. + +**Bounds are in the types, not in a caller's discipline.** A `JsonPath` is validated against a +narrow grammar — roots, members, indices, recursive descent — so a path assembled from request data +cannot become `$` and replace a whole document. A `TimeSeriesSample` series is created with a +retention or not at all; unlike a stream there is no per-append trim to fall back on. A `SearchQuery` +carries its offset, page size, and timeout, so "read the whole index" cannot be written. Every +probabilistic structure is reserved with an explicit error rate and capacity, because one created +implicitly by its first write gets server defaults and saturates into answering "probably present" +for everything. + +**The interfaces say the answers are approximate.** `probablyContains`, `estimateCount`, +`estimateQuantile` — a false-positive rate does not become a correctness bug because someone read a +method called `contains`. + +**Search is the one place the guard cannot help.** An `FT` command addresses an index, and an index +is not a key, so there is no key on the request to namespace-check. The index name is therefore a +validated type rendered with the process's namespace prefix by the operations class, and the key +prefix an index covers is rendered the same way. An index can only be created over — and queried +against — documents this process owns, and that rule lives in one method rather than in a review +checklist. `FT.DROPINDEX` is `BLOCKED` for the whole SDK: dropping an index is a destructive +operational action, and an accidental one is indistinguishable from a search that suddenly returns +nothing. + +**What is still owed:** evidence against real modules. Nothing here proves how RedisJSON, the query +engine, Time Series, or the probabilistic structures actually reply — the fixture answers with what +the design says they answer. That is Task 26's lane. + +## 19. The "dead capability property blocks" item was wrong + +Earlier notes in this delivery listed `app-bootstrap/src/main/resources/application.yml`, `src/.env`, +and `docs/registries/env-keys.yaml` as carrying dead property blocks for five removed capabilities +(cache, session, idempotency, lease, rate-limit), to be deleted together because `verifyEnvKeys` is +fail-closed. + +That is not true for at least three of them. `ca-skeleton.capabilities.rate-limit.provider`, +`.idempotency.provider`, and `.lease.provider` are read at startup by +`dev.caskeleton.bootstrap.runtime.SecretSourceValidator`, which refuses to start when a provider is +selected without its HMAC secret, and `SecretSourceValidatorTest` covers all three. Deleting those +blocks would remove a live startup check and break the test. + +`app.rate-limit.*` is a separate, also live tree bound by `EdgeRateLimitTransportSettings` in +`adapter:inbound:web`; it is not the same property as the capability selector above and the two must +not be conflated. + +The `ca-skeleton.capabilities.cache.canonical.*` and `ca-skeleton.security.redis-session.*` blocks +have no binder that a source search finds, so they may genuinely be residue — but "no binder found" +is not the same as "unused", and removing keys from a fail-closed three-file invariant on that basis +is not a change worth making without auditing each key's consumers. No cleanup was performed. + +## 20. Tasks 26–27 — the harness landed, the evidence did not + +I previously described these two as blocked on a real server. That was wrong and worth correcting: +the *evidence* needs servers, but the harness, the ACL accounts, the docs gates, and the CI wiring +are all files, and they are now in the repository. + +**What landed.** + +- `infra/redis-sdk/{standalone,sentinel,cluster}/compose.yml` — three lanes, version-parameterised so + one file serves every row of the support matrix. Sentinel runs three sentinels because a + two-sentinel quorum cannot survive losing one, and a failover test that cannot lose a sentinel is + not testing failover. Cluster runs six nodes so a promotion can be forced without losing a shard, + and waits for slot assignment before tests start. +- `infra/redis-sdk/acl/*.acl` — one account per `CommandAccess` level, each deliberately narrower + than the SDK's own rules. The account is the last boundary and a permit never widens it, so a + mistake in the SDK is still refused by the server. +- `redisTopologyTest`, a Gradle lane tagged `redis-topology` and excluded from the default unit task. + It **fails closed**: selecting it without host, port, and mode is a `GradleException`, and + `RedisTopologyEndpoint` refuses to default to `localhost:6379`. A topology test that silently + passes because it never connected is worse than not having one. +- `docs/redis/support-matrix.md`, which `RedisSupportMatrixTest` parses. A package or a capability + that is not listed fails the build, so stating the support level is part of shipping a module + rather than a follow-up someone remembers. The certified-version table says "lane declared, not + run" for all three topologies, and the test asserts that string — a certified version cannot be + claimed from a lane that has never produced evidence. +- `docs/redis/command-policy.md`, `operations.md`, `upgrade-guide.md`. The upgrade guide states why + each check exists, not just that it is required: an unclassified command is refused, but a command + whose risk changed upstream and is still classified R1 here is not; a rollback that leaves a + process holding stale script digests produces `NOSCRIPT` on every scripted call. +- `.github/workflows/redis-sdk-topology.yml`, manual-dispatch only, plus two new entries in + `.github/ci-gate-matrix.yml` — the support matrix as a release-blocking contract test, and the + topology evidence as explicitly `delegated-pending`. The gate count moved from 27 to 29. + +**What did not land: the evidence.** No assertion in `RedisTopologyContractTest` yet exercises a +promotion, a resharding, an ACL denial, or the guardrail datasets from the plan (1 MiB string, +hundred-thousand-element collections, a million-entry trimmed stream, a five-hundred-command +pipeline). Writing those assertions against a lane that has never been started would produce tests +whose first run is also their first review, so the lane is fail-closed and the support matrix says +plainly that nothing is certified. That is the honest state, and the harness is what makes closing +it a bounded piece of work rather than a project. + +## 21. The standalone lane ran, and it found five defects + +The lane in `infra/redis-sdk/standalone` was started against Redis 7.4 and +`RedisTopologyContractTest` now asserts, for every account in `infra/redis-sdk/acl`, that the +`CommandAccess` level grants exactly what the command policy catalog says it may issue. Seven tests +pass. Getting there required fixing five things that reading the files would never have surfaced: + +1. **The ACL files did not load at all.** A Redis `aclfile` accepts nothing but complete `user` + lines — no comments, no line continuations — and the server refused to start. The rationale moved + to `infra/redis-sdk/acl/README.md`, and the four accounts are concatenated into + `all-accounts.acl` because Redis takes one `aclfile`. +2. **The advanced account granted `SMEMBERS` and `SORT`.** Both are `RAW_ONLY`, so they belong to the + raw gateway account alone. This is the defect worth caring about: the ACL account is the last + enforcement boundary and a permit never widens it, so an account wider than the catalog silently + removes the second control the whole raw-gateway design rests on. +3. **The ordinary account granted `SORT_RO`,** for the same reason. +4. **The ordinary account could not run `PUBLISH`, `SUBSCRIBE`, or `PING`,** all classified `TYPED`. +5. **The ordinary account could not run `MULTI`, `EXEC`, `UNWATCH`, or `DISCARD`,** also `TYPED`. + +6. **The admin account was missing twelve read-only diagnostics** the catalog exposes: the `OBJECT`, + `PUBSUB`, and `XINFO` subcommands, `FUNCTION LIST`/`STATS`, and `CLUSTER KEYSLOT`. Closing this + also forced a decision: `FUNCTION LOAD` is `ADMIN_ONLY` but not read-only, and granting it to an + account named `admin-readonly` would make the name a lie. Loading a library is a deployment + action with its own credentials, so the assertion covers read-only `ADMIN_ONLY` commands only. + +There was also a defect in the test itself, which is worth recording because it is the failure mode +this kind of test usually dies of: `ACL DRYRUN` checks arity *before* permission, so probing a +command with the wrong number of arguments answers "wrong number of arguments" for an account that +would have been refused anyway. Reading that as a grant makes the test pass while the account is +wrong. The probe now walks argument counts until the server actually answers the permission +question. A second one followed it: a command the server does not carry answers "not found", and +skipping that without checking the catalog's minimum version is how a real ACL gap hides behind a +module that happens not to be installed. An absent command is now only tolerated when the catalog +already says the server is too old for it. + +`docs/redis/support-matrix.md` records standalone 7.4 as "ACL contract verified"; Sentinel and +Cluster remain "lane declared, not run", and `RedisSupportMatrixTest` still asserts that string. + +**Still owed on this task:** the guardrail datasets (1 MiB string, hundred-thousand-element +collections, a million-entry trimmed stream, a five-hundred-command pipeline) and the fault +injection — promotion on the Sentinel lane, resharding on the Cluster lane. Those are the assertions +`ExecutionCertainty` and `RedisSlotCalculator` were built to be checked against. + +## 22. The guardrail run found the first real SDK defect + +`LiveRedisGuardrailTest` is the first thing that puts `LettuceRedisCommandGateway` under the SDK's +own contracts against a live server. Everything before it ran against +`InMemoryRedisCommandGateway`, which is a deterministic stand-in and answers what the design says it +should — so an encoding or budgeting mistake could not show up there by construction. + +It found one immediately, and it is a good example of the class of bug a fake cannot catch: + +**The cursor-scan reply budget was sized to the requested `COUNT`.** Redis treats `COUNT` as a hint, +not a limit: it walks whole hash buckets and listpack entries and returns what it found. A real +`HSCAN` asked for 500 came back with 501, and the SDK rejected a perfectly correct reply — a refusal +the caller can neither act on nor avoid. `RedisOperationContext.scanBudget` now accepts the +configured scan ceiling plus a fixed overshoot allowance, which is still a bound: a server returning +an order of magnitude more than it was asked for is refused. All four scan sites (key, hash, set, +sorted set) use it. + +The rest of the datasets passed unchanged: the 1 MiB value ceiling holds and one byte over never +leaves the process; a hundred-thousand-field hash refuses `HGETALL` and is only reachable by cursor; +a stream trimmed to 1,000 stays trimmed while twenty thousand entries are appended; a +five-hundred-command batch reports every item positionally. + +**Still owed:** Sentinel promotion and Cluster resharding. Those need their own lanes started, and +they are where `ExecutionCertainty` and `RedisSlotCalculator` finally get checked against reality. + +## 23. The Sentinel and Cluster lanes ran, and the worst defect was not in the code + +Both remaining lanes now produce evidence. `docs/redis/support-matrix.md` records which test +produced which, and `RedisSupportMatrixTest` no longer asserts the literal string +`"lane declared, not run"` — that gate worked only until the lanes ran, and a gate that has to be +deleted the moment it binds was never a gate. It now requires every evidence claim to name a test +class that exists in the source tree, which is a rule that survives the lanes running. + +### The harness had to be fixed before it could produce anything + +Neither compose file could have worked. Both published no ports, and more importantly both would +have advertised container-internal addresses: Sentinel answers `get-master-addr-by-name` with the +address it monitors and the client dials that itself, and a cluster client reads `CLUSTER SHARDS` +and connects to every node it names. On a bridge network a host client resolves a topology it cannot +reach. Both lanes now use host networking with fixed ports, which is the only arrangement where the +address the topology advertises is the address the client can use. + +Three smaller harness defects went with it: the endpoint record assumed the declared address was a +data node (on the Sentinel lane it is a sentinel, so ACL assertions were being asked of the +sentinel's own accounts); the CI workflow passed `6379` for all three lanes; and `redisTopologyTest` +was cacheable, so Gradle reported a previous run's verdict as the current one against a lane that +had since been restarted and promoted. Lane selection is now derived from the declared mode +(`redis-topology & lane-<mode>`) so a promotion test is never selected on a standalone lane and +never silently skipped either. + +### The finding: a superseded primary keeps acknowledging writes + +This is the most serious thing this delivery has surfaced, and none of it is in the SDK's code. + +Sentinel promoted the replica at `05:56:12.503` and did not demote the old primary until +`05:56:23.529`. For those eleven seconds the client stayed connected to a primary that had already +been replaced, wrote, and was told `+OK` **2,086 times**. Every one of those writes was discarded +when the old primary resynced from the new one — the server's own log says so: +`Partial resynchronization not accepted: Requested offset for second ID was 9897663, but I can reply +up to 9731839`. Exactly **one** command failed in the whole run. + +There is no client-side signal for this. The server answered, so the driver recorded a success, the +SDK recorded `CONFIRMED_SUCCESS`, and the caller was told the write landed. A second run made the +point harder: sixteen thousand attempts, **zero** exceptions, 2,086 acknowledged writes gone. + +`SentinelFailoverObserver` counts *ambiguous* writes and its documentation called those "the ones an +operator has to reconcile". That was wrong by three orders of magnitude — the writes that actually +needed reconciling were the confirmed ones, and no counter on the client can be made to include +them. The class now says so instead of implying it measures something it cannot. + +What closes the window is server-side. Re-running the identical promotion with +`min-replicas-to-write 1` and `min-replicas-max-lag 1` cut acknowledged-and-discarded writes from +**2,086 to 1**: the orphaned primary refused 2,020 writes with `NOREPLICAS`, which the SDK already +translates to a definite, non-ambiguous failure. Both settings are in the lane, and +`acknowledgedWriteLossIsBounded` ties the tolerated loss to the configured lag window rather than to +a magic number. + +### The assertion immediately caught a second version of the same mistake + +The first run with the setting passed. The second failed, with 2,099 lost writes — because the +setting had been written into the `primary` service only. These two nodes swap roles on every +failover, so a guardrail applied to whichever one happens to start as primary stops applying the +moment the lane does the thing it exists to do. Both data nodes now take their whole configuration +from one definition, which makes the asymmetry impossible to reintroduce. Three consecutive +promotions in both directions since: 0, 0, and 1 acknowledged write lost. + +### One real translator defect + +The promotion closed the channel under an in-flight `RPUSH` and Lettuce raised a bare +`RedisException`, which matched no branch of `LettuceExceptionTranslator` and fell through to a +generic failure reported with `ambiguous=false` — that is, as a write that *definitely did not run*. +Nothing about an unrecognised failure supports that claim, and a caller who believes it retries a +non-idempotent write. The fallback now treats an unclassified write failure as ambiguous, which is +the safe direction, and two unit tests pin both branches. + +### Cluster: the arithmetic holds + +`LiveRedisClusterTest` checked `RedisSlotCalculator` against `CLUSTER KEYSLOT` over a corpus built +from the brace rules a hand-written implementation gets wrong — `{}`, `a{}b`, `foo{}{bar}`, +`foo{{bar}}zap`, `foo{bar}{zap}`, `{`, `}`, `}{`, an unclosed brace, the empty key, and non-ASCII +keys. No disagreements, and the result was reproduced independently against the server outside the +test. The rendered-key invariant holds too: the slot the SDK computes from a tag alone equals the +slot the server computes from the whole rendered key, which is what makes the two-step design sound. + +Cross-slot refusal was checked in both directions, because a guard stricter than the cluster costs +availability for nothing and a looser one sends requests that cannot succeed; the pair the guard +refuses is the pair the server answers `CROSSSLOT` for. Redirects were observed rather than assumed: +a `MOVED` names the slot the client computed, and a slot put into a real `MIGRATING`/`IMPORTING` +state answers `ASK` for an absent key and `TRYAGAIN` for a multi-key request that straddles the +migration. The lane restores the slot to `STABLE`, so a run leaves the cluster as it found it. + +Nothing in `sdk.cluster` needed changing. That is worth recording as an outcome, not treated as the +test having nothing to say: the calculator is the one piece of this SDK that silently degrades into +wrong refusals and wrong admissions if it is off by one, and it is now checked rather than assumed. + +### Where this leaves the task + +| | | +| --- | --- | +| Unit | 288 tests, 0 failures | +| Standalone lane | 14 tests, 0 failures | +| Sentinel lane | 8 tests, 0 failures, three promotions in both directions | +| Cluster lane | 14 tests, 0 failures | +| `check` + architecture/env/public-path | green for `adapter:outbound:cache-redis` | +| `verify-gate-matrix.sh` | 29 gates, 27 verified, 2 delegated-pending, OK | + +Defects found and fixed across the whole evidence effort: six in the ACL accounts, two in the ACL +test itself, one in the scan budget, four in the topology harness, one in the Sentinel lane's +configuration, one in the exception translator, and one documentation claim that was wrong by three +orders of magnitude. + +`:app-bootstrap:test --tests '*CleanArchitectureTest'` passes. It briefly did not, on +`NO_UUID_RANDOM_IN_CONTROLLER` in `application.fileserver.cleanup.CleanupItem` — untracked +in-progress work from a different feature that was being edited while this evidence ran. The +identifier factories have since moved to `CleanupRequest` and no direct `UUID.randomUUID` or +`UuidCreator` call remains in `application-core`, so the rule is satisfied by the current sources +rather than waived. + +**Task 20 is the only implementation task left.** + +## 24. Task 20 — the fixture had to learn to defer before the contract meant anything + +Task 20 was deferred back at section 15 for a reason that turned out to be the whole task: the +in-memory fixture executes every command the moment it is called, so a transaction written against +it would have passed while proving the opposite of what it claimed. The writes would already have +happened before the commit, and a watch conflict would have had nothing left to discard. + +The controller chose the full option — every command available inside the window, and the fixture +reworked to match — over a narrow hand-picked subset. + +### Deferral is one property, not a hundred and eleven + +`RedisCommandGateway` has 111 methods and every one of them returns a `CompletionStage`. That is not +incidental: deferral is a property of the *connection*, so it can be implemented once rather than +per command. + +On the production side it costs nothing at all. Lettuce already defers everything issued after +`MULTI` and completes those futures from the `EXEC` reply, so `LettuceRedisCommandGateway` needed no +change to any existing method — only the five new seam methods (`watch`, `unwatch`, +`beginTransaction`, `commitTransaction`, `discardTransaction`). `commitTransaction` returns a +boolean rather than a list of results, because the per-command stages resolve themselves and the +only thing `EXEC` alone can say is whether it ran. + +On the test side, `DeferringRedisCommandGateway` is a `java.lang.reflect.Proxy` that records an +invocation, hands back an unfinished future, and replays it against the fixture at commit — which is +exactly when Redis runs it. The 1,996-line fixture was not edited for it. The consequence that +matters: a command added to the seam later cannot forget to be transactional. + +The one part that does need the data is the watch check, so that lives in the fixture. It hashes the +watched key's current contents rather than incrementing a counter at each of the sixteen mutation +sites — a counter is something a seventeenth mutation can silently fail to update, and a hash is not. + +### What the contract refuses to let a caller do + +`QueuedReply.value()` throws before the commit. The alternative — returning `null` or a zero for a +command the server has only answered `+QUEUED` to — is the trap the type exists to remove. + +`TransactionResult` reports exactly two outcomes, "executed" and "a watched key changed so nothing +ran", and neither is a rollback. Redis has none: a command that fails at runtime inside `EXEC` does +not undo the ones around it, and the proxy reproduces that faithfully by failing one future and +leaving the rest alone. + +`RedisTransactionQueue` is write-only, which is a contract rather than an unfinished surface. A read +inside the window cannot be branched on — its reply does not exist until every command has already +been chosen — so accepting one would only offer a way to write code that looks conditional and is +not. Reads a transaction depends on belong before it, under `WATCH`. + +Queued commands go through `QueueingRedisCommandExecutor`, which is `SyncRedisCommandExecutor` with +the wait removed and *nothing else* changed. The same `CommandPolicyGuard` admits them, so namespace, +slot, permit, and budget rules hold identically: a transaction is not a way around the guard, and a +test asserts that a foreign-namespace key is refused inside a window exactly as it is outside one. + +### Three defects the tests found + +1. **A callback returning nothing crashed the transaction.** `Optional.of` on a null body result + threw an NPE after a perfectly successful commit. A transaction with no interesting return value + is entirely normal, so the result now carries an empty value for it and the invariant only forbids + a value on a transaction that did not execute. +2. **`RedisTransactionQueue.delete` could never succeed.** `DEL` is R2 in the catalog because it + accepts any number of keys, so it needs a permit and a budget even when a transaction queues + exactly one. The queue presents the SDK's own permit rather than making every caller thread one + through for a single-key delete. +3. **The first conflict test was contending with itself.** It wrote the watched key through the same + gateway — that is, from inside the very window it was supposed to be contending with — so the + write was queued rather than applied and the transaction timed out instead of conflicting. A + competing writer has to come from another connection, and the test now has one. This is the kind + of mistake that would have produced a green test if the fixture had not been deferring. + +| | | +| --- | --- | +| Unit | 296 tests, 0 failures | +| `check` | green for `adapter:outbound:cache-redis` | + +**Every implementation task in the plan is now done.** diff --git a/docs/superpowers/plans/2026-08-10-httpclient-platform-activation-and-env-ssot.md b/docs/superpowers/plans/2026-08-10-httpclient-platform-activation-and-env-ssot.md new file mode 100644 index 0000000..6ab0026 --- /dev/null +++ b/docs/superpowers/plans/2026-08-10-httpclient-platform-activation-and-env-ssot.md @@ -0,0 +1,1333 @@ +# HTTP Client Platform — Activation Boundary and ENV SSOT Implementation Plan + +> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking. + +**Goal:** Make the HTTP Client platform an genuinely optional capability that is off unless +`APP_HTTPCLIENT_ENABLED=true`, binds its settings strictly and only when on, and has a single +declared environment surface that a test proves is complete. + +**Architecture:** The repository already solved this problem once, for the HTTP Fileserver platform. +`CaSkeletonApplication` excludes `dev.caskeleton.bootstrap.autoconfigure.*` from its component scan, +so a configuration in that package is reachable *only* through an entry listed in +`META-INF/spring/org.springframework.boot.autoconfigure.AutoConfiguration.imports`. Putting the +master switch on that single entry makes "off" a structural fact: the class is never processed, so +nothing it imports is discovered, no settings are bound and no runtime resource is created. HTTP +Client is migrated onto that same shape — one gated `@AutoConfiguration`, importing the existing +nine configurations, which move out of the scanned package with it. + +The settings become one strictly-bound record tree rooted at `app.httpclient`, with clients and +dynamic targets as *indexed lists carrying their own `name`* rather than maps keyed by name, so the +environment form is unambiguous and duplicate/colliding names are a startup failure rather than a +silent overwrite. + +**Tech Stack:** Java 21, Spring Boot 4.0.0, Gradle multi-module, JUnit 5 + AssertJ, +`ApplicationContextRunner`, `Binder` + `NoUnboundElementsBindHandler`. + +## Deviations found during execution + +Two things in this plan turned out to be wrong when the tests were run. Both are recorded here +rather than edited away, because the reason each was wrong is the useful part. + +**1. `NoUnboundElementsBindHandler` cannot police environment variables.** Spring binds +`APP_HTTPCLIENT_CLIENTS_0_BASE_URL` to `app.httpclient.clients[0].base-url` by mapping the requested +property name back to an environment name, but it *enumerates* the same variable as +`app.httpclient.clients[0].base.url` — underscores become dots, never hyphens. The strict handler +compares against that enumeration, so pointing it at the system environment reports every correctly +spelled hyphenated key as unbound while still saying nothing about a genuinely misspelled one. (The +Fileserver platform does not hit this only because its prefix, `app.fileserver-platform`, makes the +dotted forms fall outside the prefix entirely — an accident, not a design.) + +The fix is `HttpClientEnvironmentKeys`: derive the accepted variable names from the record tree and +reject an `APP_HTTPCLIENT_` variable that is not among them. Strict binding still covers every other +property source. This is stronger than the plan's original intent, not weaker — the handler could +never have caught a misspelled environment variable at all. + +**2. The field manifest does not live in `docs/registries/`.** That directory is a fail-closed +catalog of exactly eight contract registries, enforced by `ContractRegistrySchemaGovernanceTest`, +with a fixed per-row schema (`owner_branch`, `compatibility_impact`, `required_test`). A +field-to-variable mapping has none of that shape, and adding a ninth file would have meant loosening +a gate rather than satisfying one. The manifest is `docs/httpclient/env-fields.yaml`; every path +below that says otherwise is superseded. + +## Global Constraints + +- Commit policy is `human-only`. Agents do not stage, commit, amend or push. Every "Commit" step in + this plan is a **stop point where the human commits**; the agent reports the intended message. +- Owning leaf for all Java changes: `app-bootstrap`, Gradle path `:app-bootstrap` + (`src/config/architecture/modules.json` is the SSOT). Focused test: + `cd src && ./gradlew :app-bootstrap:test --console=plain`. +- No new project dependency edges. This plan moves and gates existing wiring; it must not make + `app-bootstrap` depend on anything it does not already depend on. +- Package root for new bootstrap code: `dev.caskeleton.bootstrap.autoconfigure.httpclient`. +- Configuration prefix: `app.httpclient`. Canonical environment form: `APP_HTTPCLIENT_*`. +- One public top-level type per file, file name equal to the type name + (`verifyOneTypePerFile`, code-conventions I6). +- `verifyEnvKeys` enforces a three-way lock-step between `src/.env`, + `src/app-bootstrap/src/main/resources/application.yml` and `docs/registries/env-keys.yaml`: + every required (`${VAR}` with no default) placeholder must exist in `.env`; every `.env` key must + be referenced by some `application.yml` placeholder; every `APP_` key in `.env` must be registered + in `env-keys.yaml`. Only `APP_HTTPCLIENT_ENABLED` goes through that gate — see Task 3 for why the + per-client surface is registered in a separate field manifest instead. +- The activation contract, verbatim from the review: + - toggle missing or `false` → zero HTTP properties/binder/provider/registry/gateway/endpoint/ + thread/resource beans; + - toggle present but not a strict boolean (blank, `yes`, `1`) → **not** silently enabled; + - `true` → strict bind, then full validation, then runtime resources; + - `true` with no clients → startup failure carrying the code `HTTPCLIENT_ACTIVE_WITHOUT_CLIENTS`; + - the actuator endpoint is registered only under the master flag. + +## Out of scope for this plan + +This plan is review step 1 and step 2 only. It does **not** address the call-execution kernel (P0 #3, +#5, #6), dynamic-target DNS pinning (P0 #4), the Reactor Stable contract row (P0 #7), the HTTP/3 +provider (P0 #8), or any P1/P2 item. Those are separate plans and each needs its own working +software. What this plan must not do is make any of them harder: the settings tree it introduces is +the input a later `ValidatedClientPlan` compiler will consume. + +## File Structure + +**Moved** (`git mv`, package statement and imports updated, contents otherwise unchanged unless a +task says so) — from `src/app-bootstrap/src/main/java/dev/caskeleton/bootstrap/httpclient/` to +`src/app-bootstrap/src/main/java/dev/caskeleton/bootstrap/autoconfigure/httpclient/`: + +| File | Responsibility after the move | +| --- | --- | +| `HttpClientTransportAutoConfiguration.java` | Stable transport providers.

A second review started four +Docker lanes, wired the production code to them, and found that several items marked done were +done in the sense that the code existed, not in the sense that it worked. What follows is what that +round changed, and what it changed because of. + +### The readiness group could not start at all + +`management.endpoint.health.group.readiness.include` named `redisRequired`, a contributor that only +exists when a correctness role selected Redis. Boot validates group membership and does **not** +tolerate a conditional member being absent, so every Redis-off and cache-only deployment failed at +startup with `Included health contributor 'redisRequired' in group 'readiness' does not exist`. The +comment in `application.yml` asserted the opposite. + +The group now names only unconditional contributors, and +`RedisReadinessGroupPostProcessor` appends `redisRequired` from `RedisCorrectnessRoles` — the same +predicate the bean's `@Conditional` asks, so membership and existence cannot drift. +`RedisReadinessGroupPostProcessorTest` boots a real Actuator context in each of the three shapes; +putting the name back in the shipped file makes two of them fail exactly as production did. + +### Redis on composed no capability + +`APP_REDIS_ENABLED=true` produced a client, an owner and a health contributor. Every semantic port +count was zero, so a deployment that selected `redis` for its rate limiter started, reported +healthy, and had no rate limiter. `RedisCapabilityConfig` composes cache, rate limit, lease and the +owner-safe idempotency store, each on its own selector. + +The idempotency guard was also counting `application.idempotency.IdempotencyStorePortV2`, which no +provider implements — the implemented contract is the one in `…idempotency.v2`. Selecting `redis` +therefore required a bean nothing could supply. Driving the V2 store from an executor remains +outstanding and is named as such rather than covered by a guard that cannot see it. + +### Four key prefixes, and an ACL that matched none of them + +Each capability joined its own `namespace-application` / `namespace-environment` pair in its own +order, so the cache wrote `ca-skeleton:prod:…` while the ACL granted `~prod:*`. `CapabilityKeyspace` +renders every capability below one `RedisNamespace`, and the per-capability namespace keys are +deprecated. + +The scripted capabilities also ran `EVALSHA` on the application account, which does not have it. +Lanes now carry a `RedisCredentialRole`; the topology factory builds one client per configured +role, so the `SCRIPT` lane authenticates as the advanced account and the account that reads a cache +entry still cannot execute a script. `LiveRedisSemanticPortsTest` proves both directions against a +real server. + +### Cluster transactions were impossible, and multi-key WATCH was refused + +`beginTransaction()` on a live cluster failed by design: every lane opened the slot-routing +connection, which cannot own a window. `RedisTransactionRunner` derives a routing key and pins the +lane to the node that owns the slot. Fixing that surfaced a second defect a cluster was not needed +for — `watch()` presented no multi-key permit, so watching more than one key was rejected +unconditionally, which is most optimistic transactions. + +### The fixtures could not fail + +Every ACL account was `nopass`, which accepts any password: every assertion about authentication +passed for the same reason a typo would have. The accounts carry real passwords and a wrong one is +now asserted to produce `WRONGPASS`. The cluster lane's readiness helper checked +`CLUSTER INFO` unauthenticated, so it never matched, never exited, and `up --wait` returned while +slots were still being assigned; a `ready` gate now blocks on `cluster_state:ok`. + +### TLS was reachable only by hand + +`tls` is a lane of `redisTopologyTest` and of the CI matrix. Trust material resolved with +`new File(...)` broke `classpath:` references, and resolving it purely through the resource loader +breaks mounted paths — both shapes are ordinary, and both are supported. + +### Gates that could report success for a lane they did not run + +`afterTest` fires for skipped tests too, so the "ran something" check could be satisfied by a run +that skipped everything. Lanes now declare the classes they exist to run and a floor for the +executed count, and a skipped test fails the run. `verifyEnvKeys` gained a check for registered +keys that nothing reads — no typed property, no yaml reference, no `.env` entry, no Java consumer — +which found eight orphaned Redis keys beyond the two the review named. + +### Verified + +| Lane | Result | +| --- | --- | +| standalone | 25 tests | +| sentinel | 27 tests | +| cluster | 29 tests, including a same-slot transaction and a cross-slot refusal | +| tls | 4 tests, filesystem and classpath CA | + +Repository: 3594 tests, 0 failures. `verifyCleanArchitectureDependencies`, +`verifyPublicPathSnapshot`, `verifyEnvKeys`, `CleanArchitectureTest`, `verify-gate-matrix.sh` +(37 gates) and `verify-gradle-wrapper.sh` all pass. + +### Still open + +- **Session port.** No provider-neutral session contract exists in `application-core` or + `shared-contract`; it went with the previous generation.

Goals + +1. Make `application-core` free of Spring, SLF4J, Logback, Log4j, JUL logging, and Micrometer types + and main/test classpath dependencies. +2. Express confirmed outbox publication failures as a typed application-owned outbound port. +3. Keep report data safe by construction: no payload, idempotency key, arbitrary field map, log + level, message template, or framework logger crosses the port. +4. Implement structured failure reporting in `adapter:outbound:messaging`. +5. Keep `app-bootstrap` limited to final wiring and runtime logging configuration. +6. Preserve outbox state-machine behavior, transaction boundaries, per-event continuation, and + at-least-once semantics. +7. Ensure a reporting backend failure cannot change a persisted `FAILED`/`DEAD` outcome or stop the + remaining relay batch. +8. Remove the duplicate, misleading fail-open WARN currently emitted by the fail-closed outbox + publisher. +9. Add source- and dependency-level guardrails that prevent framework observability from returning + to application-core. + +## 4. Non-Goals + +- This change does not redesign outbox claiming, FIFO ordering, retry backoff, in-flight recovery, + or broker selection. +- It does not turn operational failures into domain events or business audit records. +- It does not deliver a failure report through the same broker/outbox path; that would recurse when + the broker is the failing dependency. +- It does not add a generic `LoggerPort`, severity API, string template API, or untyped field map. +- It does not add a twentieth module or a general observability adapter family. +- It does not recover the missing `.harness` policy registry; the implementation waits for that + independently governed recovery. +- It does not change public HTTP response contracts. + +## 5. Semantic Classification + +An outbox publish failure is an **application operational event**: + +- the application state machine decides whether the confirmed result is retryable `FAILED` or + terminal `DEAD`; +- the persistence transition is authoritative; +- an infrastructure adapter renders that fact as a structured operational record; +- metrics and runbooks consume the result for operations. + +It is not a business audit event. It has no actor/action audit semantics, is not retained as an +immutable audit ledger, and must not be used as proof of a business transaction.

The messaging module owns the concrete +rendering because its local responsibility explicitly includes outbox publication adaptation, it +already depends on application/shared contracts, and it already has the SLF4J API. Bootstrap +selects and injects the adapter but does not implement the port. + +## 7. Application Contract + +### 7.1 Port + +```java +@FunctionalInterface +public interface OutboxRelayFailureReportPort { + + /** + * Attempts to report a confirmed FAILED or DEAD relay transition. + * + * <p>The implementation must not throw. The report is operational evidence, while the persisted + * outbox state and returned relay outcome remain authoritative. + */ + void report(OutboxRelayFailureReport report); +} +``` + +The use case also contains a defensive non-throwing invocation boundary. This makes the invariant +explicit even if a custom implementation violates the port contract. + +### 7.2 Safe immutable report + +```java +public record OutboxRelayFailureReport( + OperationalError code, + String eventId, + String eventType, + String aggregateId, + String correlationId, + int attemptCount, + Instant nextAttemptAt, + RuntimeException cause) { + + public static OutboxRelayFailureReport retryableFailure( + String eventId, + String eventType, + String aggregateId, + String correlationId, + int attemptCount, + Instant nextAttemptAt, + RuntimeException cause); + + public static OutboxRelayFailureReport deadLetter( + String eventId, + String eventType, + String aggregateId, + String correlationId, + int attemptCount, + RuntimeException cause); +} +``` + +Invariants: + +- `code` is exactly `OUTBOX_PUBLISH_FAILED` or `OUTBOX_DEAD_LETTER`. +- identifiers and type names are non-null and non-blank. +- `attemptCount` is at least one. +- `nextAttemptAt` is required for `OUTBOX_PUBLISH_FAILED` and absent for + `OUTBOX_DEAD_LETTER`. +- `cause` is required. +- the record has no `payload`, `idempotencyKey`, logger, severity, template, or arbitrary map. + +Static factories remove invalid combinations from ordinary call sites. The record deliberately +accepts an allowlisted set of safe operational metadata plus the original cause rather than an +`OutboxEvent`, whose full shape includes payload and idempotency data. + +## 8. Relay Flow and Failure Semantics + +The report attempt happens only after the corresponding write transaction succeeds: + +```text +publish throws + ├── retry remains + │ ├── inWrite(markFailed) succeeds + │ ├── attempt OUTBOX_PUBLISH_FAILED report + │ └── return FAILED + └── attempts exhausted + ├── inWrite(markDead) succeeds + ├── attempt OUTBOX_DEAD_LETTER report + └── return DEAD +``` + +Behavior matrix: + +| Situation | Persistence | Report | Relay behavior | +|---|---|---|---| +| Publish succeeds, `markPublished` succeeds | `PUBLISHED` | none | return `PUBLISHED` | +| Publish succeeds, `markPublished` fails | remains recoverable `IN_FLIGHT` | none | propagate store failure; scheduler retries later | +| Publish fails, `markFailed` succeeds | `FAILED` | attempt retryable report | return `FAILED`; continue batch | +| Publish fails, `markDead` succeeds | `DEAD` | attempt dead-letter report | return `DEAD`; continue batch | +| Publish fails, status transition fails | no confirmed FAILED/DEAD transition | none | propagate store failure; do not emit a false report | +| Reporter violates its contract and throws | already `FAILED` or `DEAD` | attempted | contain reporter exception; preserve outcome and continue batch | + +The report is mandatory as an **attempt** after every confirmed failure transition. A production +NOOP binding is forbidden. No logging system can guarantee durable emission, so metrics and +persistence remain independent evidence when the logging backend itself is impaired. + +## 9. Structured Logging Contract + +The messaging adapter emits ERROR through SLF4J 2's fluent key-value API. The runtime Logstash +encoder serializes key-value pairs as top-level JSON fields, while the message also carries a short +safe summary for local pattern output. + +Common fields: + +- `error.code` +- `error.category` +- `dependency_name` +- `dependency_type=messaging` +- `outcome` +- `event_id` +- `event_type` +- `aggregate_id` +- `correlation_id` +- `attempt_count` +- `runbook_link` + +Retry-only field: + +- `next_attempt_at` + +Mappings: + +| Code | Outcome | Runbook | +|---|---|---| +| `OUTBOX_PUBLISH_FAILED` | `FAILED` | `runbook://outbox/publish-failed` | +| `OUTBOX_DEAD_LETTER` | `DEAD` | `runbook://outbox/dead-letter` | + +The throwable is attached as the log cause. Payload, idempotency key, message envelope, recipient, +and arbitrary exception-derived key/value fields are never added. Existing runtime masking remains +defense in depth rather than the primary privacy boundary. + +## 10. Duplicate Logging Removal + +`OutboxMessagePublishAdapter` currently uses `FailOpenDependencyLogger` for a fail-closed operation: +it emits WARN and rethrows. That logger's documented meaning is an optional dependency failure where +the use case still succeeds. The relay then emits a second ERROR after deciding `FAILED` or `DEAD`. + +After this refactoring: + +- `OutboundMessagePublisher` keeps `FailOpenDependencyLogger` because its contract is genuinely + fail-open. +- `OutboxMessagePublishAdapter` maps/sends and surfaces failures without logging. +- `Slf4jOutboxRelayFailureReportAdapter` emits the single canonical ERROR after the application + state transition succeeds. + +This removes duplicate records and makes severity match the confirmed outcome. + +## 11. Dependency Purity + +### 11.1 Gradle declarations + +`application-core` production declarations become: + +```groovy +dependencies { + implementation project(':domain-core') + implementation project(':shared-contract') +} +``` + +The root test baseline gives application-core JUnit Jupiter and AssertJ directly rather than Spring +Boot test starters. Spring dependency-management may remain build tooling, but Spring/logging/ +Micrometer artifacts must not appear on application-core main or test compile/runtime classpaths. +Static-analysis tool configurations are outside this classpath rule. + +### 11.2 Gradle verification + +A blocking `verifyApplicationCoreDependencyPurity` task checks both: + +1. application-core production configurations contain no declared external module dependency; +2. `compileClasspath`, `runtimeClasspath`, `testCompileClasspath`, and `testRuntimeClasspath` + resolve no Spring, SLF4J, Logback, Log4j, or Micrometer component. + +The task is wired into `:application-core:check`. + +### 11.3 Source verification + +ArchUnit adds an application logger/metrics ban covering: + +- `org.slf4j..` +- `java.util.logging..` +- `ch.qos.logback..` +- `org.apache.logging.log4j..` +- `io.micrometer..` + +An intentional application-package fixture proves the rule is not vacuous. The Gradle task remains +necessary because ArchUnit cannot detect an unused starter that is merely present on the classpath. + +## 12. Module Ownership Alternatives + +### 12.1 Messaging adapter — selected + +Advantages: + +- highest cohesion with outbox publication failure; +- existing application/shared/support and SLF4J dependencies; +- no new project edge; +- reusable by composition roots other than app-bootstrap; +- preserves bootstrap as wiring rather than an adapter collection. + +Counterargument: reporting is observability rather than broker transport. The selected design +answers this by keeping the contract application-owned and the concrete class narrowly +outbox-specific; generic logging support does not move into messaging. + +### 12.2 Shared outbound support — rejected + +Advantages: + +- already owns reusable correlation and fail-open dependency logging; +- would centralize logging backend calls. + +Counterargument: the support module explicitly keeps feature-specific behavior in the owning leaf. +Putting `FAILED`/`DEAD` outbox semantics there makes a low-level shared module feature-aware. +Generalizing the interface would create the forbidden logger abstraction. + +### 12.3 App bootstrap — viable fallback, not selected + +Advantages: + +- owns runtime logging bootstrap and final wiring; +- already contains outbox metrics and structured Logstash usage. + +Counterargument: each feature-specific reporter placed there expands the composition root into an +adapter implementation module and prevents straightforward reuse by another composition root. + +### 12.4 Direct `slf4j-api` in application-core — rejected + +This is the smallest dependency diff and would remove Spring Boot transitive dependencies, but it +retains framework coupling, contradicts the module rule, and tests formatting calls instead of +application meaning. + +### 12.5 Generic operational event publisher — deferred + +A typed cross-feature operational event sink could become valuable when several application +features need the same routing. Introducing it for two outbox outcomes is premature, risks an +untyped field bag, and must never be implemented through the failing outbox broker. + +## 13.

This is consistent with a top-level shell +glob used during copying or staging. That is a falsifiable root-cause hypothesis, not proof of the +exact command that was used. + +## 3. Goals + +1. Prefer byte-for-byte recovery of the authoritative hidden control-plane assets; when that source + is unavailable or incomplete, require an explicit human reconstruction decision and record new + provenance without presenting reconstruction as restoration. +2. Restore the 19-leaf module registry and the harness behavior approved in the 2026-07-20 design. +3. Make a fresh checkout fail early with a precise control-plane error before Gradle configuration. +4. Enable repository Actions on Gitea 1.27.0 and provide an isolated, repository-scoped runner. +5. Keep `.github/workflows` as the canonical workflow directory while preventing an accidental + `.gitea/workflows` shadow. +6. Restore a single release-blocking fan-in status and the complementary vulnerability status. +7. Make public-path, Trivy suppression, dependency-lock, and architecture gates fail closed. +8. Make Docker builds consume the same root registry without duplicating the registry under `src/`. +9. Pause Renovate automerge until required CI statuses and lockfile refresh behavior are proven. +10. Bring README, gate-matrix, workflow, and physical-path claims back into parity. + +## 4. Non-Goals + +- This recovery does not change production Java behavior or module boundaries. +- It does not redesign the 19-leaf registry approved in the 2026-07-20 harness policy design. +- It does not silently synthesize hidden policy files or present reconstructed content as recovered + authority. +- It does not store a Gitea API token, runner registration token, or repository secret in Git. +- It does not enable deployment to a production environment. Release artifact construction and + scanning are restored, but a separate deployment decision remains human-owned. +- It does not re-enable Renovate automerge merely because workflow files exist; branch protection + and a successful dependency-update exercise are also required. + +## 5. Governing Invariants + +### 5.1 Recovery mode is an explicit human decision + +The original working tree, archive, or source repository that produced the 2026-07-20 harness +design is the preferred recovery authority. Before copying anything into this repository, the +recovery source must be inventoried and hashed outside the worktree. + +The minimum authoritative set is: + +- `.harness/` +- `.agents/` +- `.claude/` +- `.codex/` +- `.github/` +- `.tool-versions` +- `.trivyignore.yaml` +- `.gitattributes` + +The human owner chooses one of two modes and records it before repository writes: + +**Mode A — authoritative restore.** All minimum paths exist in the recovery source. The executor +hashes them, copies them byte-for-byte, proves source/destination equality, and preserves their +native provenance. + +**Mode B — controlled reconstruction.** The original source is unavailable or incomplete. The +human records that fact and explicitly authorizes reconstruction from the approved +[`2026-07-20-harness-policy-engine-design.md`](2026-07-20-harness-policy-engine-design.md), +[`2026-07-20-harness-policy-engine.md`](../plans/2026-07-20-harness-policy-engine.md), the tracked +Gradle/module sources, and this design. Reconstructed artifacts receive new hashes and a +`controlled-reconstruction` provenance record. Schema, renderer parity, mutation coverage, Gradle +project discovery, and architecture dependency checks must pass before the new artifacts can act as +authority. + +The first Mode B inventory covers the reconstructed harness and generated platform assets only. +After Tasks 3-6 and every later change to a covered path are final, the executor regenerates one +complete, sorted SHA-256 inventory for `.harness`, `.agents`, `.claude`, `.codex`, `.github`, +`.tool-versions`, `.trivyignore.yaml`, `.gitattributes`, `.dockerignore`, and +`docs/security/public-paths-snapshot.txt`. The provenance record names that final evidence path. +Only this post-change inventory is used for the human handoff. + +Implementation stops only until the human chooses Mode A or Mode B. An incomplete Mode A export +must never be filled silently. It may instead cause the human to switch the recorded decision to +Mode B. The tracked `AGENTS.md`, `CLAUDE.md`, and design documents are evidence of intended +behavior, but reconstructed schemas, agents, registries, and workflows become authoritative only +after the required new evidence passes. + +### 5.2 Human-only commit policy + +Recovery and implementation may leave reviewed changes in the working tree, but agents do not +stage, commit, amend, or push. A human decides commit boundaries after reviewing recovery hashes, +generated-file parity, test evidence, and Gitea status checks. + +### 5.3 One registry and one workflow source + +`.harness/project/modules.yaml` remains the only module-edge and focused-command registry. +Container builds copy that file from the repository root; they do not create a second copy under +`src/`. + +`.github/workflows` remains the canonical workflow directory because the repository documentation +and portability contract already point there. Gitea's default `WORKFLOW_DIRS` value is +`.gitea/workflows,.github/workflows`, and Gitea uses the first directory that exists. Therefore +`.gitea/workflows` must remain absent unless the project later adopts a generated-mirror design +with an explicit parity check and a separate approved specification. + +### 5.4 Fail closed before expensive work + +CI runs a repository control-plane preflight before invoking build or container work. Missing +policies, workflow shadowing, a missing committed public-path baseline, or an incomplete structured +Trivy contract fail immediately. Once Java/Gradle is available, that same blocking preflight runs +`verifyTrivyignore`; the vulnerability scanner must explicitly consume `.trivyignore.yaml`. + +## 6.

Design Decisions + +### 7.1 Recovery gate and physical control-plane manifest + +After Mode A restore parity or Mode B reconstruction evidence passes, the harness gains a small +physical manifest at `.harness/project/control-plane.yaml`. It lists required files, required +directories, the canonical workflow directory, and the forbidden shadow directory. The file uses +JSON syntax, matching the 2026-07-20 design's stdlib-only JSON-as-YAML convention. + +`.harness/validators/validate_control_plane.py` reads the manifest and reports every missing path in +one deterministic result. It also rejects `.gitea/workflows`. Its tests live at +`.harness/tests/test_control_plane.py`. + +This validator checks physical availability only. It does not duplicate module edges, risk rules, +or workflow gate semantics. Module semantics stay in `modules.yaml`; the gate matrix stays in +`.github/ci-gate-matrix.yml`. + +### 7.2 Gitea Actions and runner control + +The repository owner enables `Enable Repository Actions` in the repository settings. The public API +must then report `has_actions: true`. + +The runner is registered at repository scope, uses an isolated Docker execution mode, and exposes +the exact `ubuntu-22.04` label used by the workflows. Registration credentials remain in the runner +host's protected state or secret manager. They never enter workflow YAML, shell history captured by +CI, Docker image layers, or repository files. + +An authenticated repository runner inventory must show at least one enabled, online runner before +the first required workflow is treated as operational. The previous unauthenticated `401` remains +an expected access-control result. + +### 7.3 Canonical workflow directory and Gitea shadowing + +The recovery restores canonical workflows under: + +- `.github/workflows/ci-quality-gates.yml` +- `.github/workflows/build-release-supply-chain.yml` +- `.github/workflows/dependency-vulnerability.yml` + +No workflow is copied to `.gitea/workflows`. With Gitea's default directory ordering, the mere +existence of `.gitea/workflows` would cause `.github/workflows` to be ignored. The preflight +validator makes that shadow a blocking failure. + +Instance administration must confirm that `[actions].WORKFLOW_DIRS` still contains +`.github/workflows`. If the instance has a non-default value that excludes it, the administrator +changes the instance setting or the project stops before enabling required checks. + +### 7.4 Preflight and release-gate topology + +`ci-quality-gates.yml` starts with `control-plane-preflight`. No Gradle, test, or Docker job runs +unless preflight succeeds. + +The release-blocking fan-out includes: + +- restored harness unit and mutation suite +- `validate_modules.py`, renderer parity, policy parity, and `verify-gate-matrix.sh` +- structured Trivy validation through `verifyTrivyignore` +- Gradle wrapper launch and Java 21 assertion +- `verifyDependencyLocks` +- `verifyCleanArchitectureDependencies` +- focused ArchUnit coverage +- `verifyPublicPathSnapshot` +- `test` +- `check` +- production and sample Docker builds +- reproducible artifact verification when owned by the restored workflow contract + +The workflow ends with a single `release-gate` job that uses `if: always()` and fails unless every +release-blocking dependency succeeded. Quarantine remains non-blocking and is intentionally absent +from the fan-in. + +Gitea cannot express `needs` across separate workflow files. The dependency vulnerability workflow +therefore publishes its own blocking status. Protected branches require both the quality +`release-gate` status and the vulnerability status. + +### 7.5 Missing contracts + +The recovery must restore `.tool-versions`, `.gitattributes`, `.trivyignore.yaml`, workflow scripts, +gate matrix, CODEOWNERS, and vulnerability policy from the authoritative source. + +The structured empty Trivy contract is retained even when there are no suppressions: + +```yaml +vulnerabilities: [] +licenses: [] +misconfigurations: [] +secrets: [] +``` + +The quality preflight and release-tag preflight both run `verifyTrivyignore`. The independent +vulnerability workflow also runs that verifier and passes +`trivyignores: .trivyignore.yaml` to the pinned Trivy action, so a present-but-unconsumed or +malformed suppression file cannot satisfy a required status. + +`docs/security/public-paths-snapshot.txt` becomes a committed baseline. The current approved value +derived from `src/.env` is `/api/healthcheck`. A missing baseline is a failure, not an instruction to +create one during verification. + +The read-only `verifyPublicPathSnapshot` task compares the committed baseline to `src/.env`. +Generation moves to a separate, explicitly approved update task. `check` and the quality workflow +both depend on the read-only verification task. + +### 7.6 Dependency locks + +All 19 leaf modules retain Gradle strict locking. CI runs `verifyDependencyLocks` before compile or +test jobs so an incomplete Renovate update fails with a direct lock error. + +The only supported lock refresh command remains: + +```bash +cd src +./gradlew resolveAndLockAll --write-locks --console=plain +``` + +A dependency update is acceptable only when the declaration, all affected `gradle.lockfile` files, +and the quality gate agree. CI never runs `--write-locks`. + +### 7.7 Docker root context + +Compose changes the app build context from `src/` to the repository root and addresses the +Dockerfile as `src/Dockerfile`. Both Dockerfiles keep the Gradle project at `/build/src` and copy: + +1. `.harness/project/modules.yaml` to `/build/.harness/project/modules.yaml`; +2. wrapper, build descriptors, and lockfiles to `/build/src`; +3. the complete `src/` tree only after dependency verification. + +A root `.dockerignore` replaces the context role previously owned by `src/.dockerignore`. It +excludes Git metadata, build output, IDE state, environment files, and secrets, while explicitly +allowing the module registry, wrapper, build descriptors, lockfiles, and Java/resources trees. + +This preserves a single registry and makes local Compose, production image, sample image, and CI use +the same context contract. + +### 7.8 Renovate safety state + +`renovate.json` sets `automerge: false` for every update type during recovery. The current comment +already states that automerge requires trustworthy CI, while the repository currently has no +operational Actions unit. + +Limited patch/pin/digest automerge can be reconsidered only after all of the following are observed: + +1. repository API reports `has_actions: true`; +2. an authenticated runner inventory reports an online runner; +3. protected branches require both blocking statuses; +4. a real Renovate dependency pull request updates strict lock state and passes; +5. a deliberately stale lockfile fails `verifyDependencyLocks`. + +The configuration description must also stop claiming that the project has +`gradle/libs.versions.toml` unless the project separately adopts a version catalog. + +### 7.9 Documentation parity + +Root and `src/` README files must point to paths that exist in Git and commands that pass from a +fresh checkout. The control-plane validator covers required physical paths, and the restored +README-command and gate-matrix checks cover executable behavior. + +The documentation must distinguish: + +- Gitea repository Actions enablement from workflow files; +- unauthenticated runner API access from authorized runner health; +- `.github/workflows` as canonical from `.gitea/workflows` as a shadow risk; +- lock verification from lock regeneration; +- read-only public-path verification from approved baseline update. + +## 8. Phased Recovery + +### Phase 0 — Preserve evidence + +Capture the current revision, clean status, missing-path evidence, Gitea version, repository +Actions state, and runner authorization behavior. Hash the authoritative recovery source before +copying it. + +### Phase 1 — Establish authority + +The human chooses Mode A or Mode B. Mode A restores the hidden asset set byte-for-byte and verifies +source equality. Mode B reconstructs from the two approved 2026-07-20 documents, records new +provenance/hashes, and runs schema, renderer-parity, mutation, Gradle discovery, and architecture +checks. The executor then writes a controller-approved overlay to the recorded recovery evidence +path, invokes the recovered resolver with that file, persists the resolved packet plus packet/rule +checksums, and proves deterministic re-resolution. Task 3 cannot start until those exact artifacts +verify. + +### Phase 2 — Establish fail-fast local gates + +Add the physical control-plane manifest and validator. Restore missing security contracts and make +the public-path baseline fail closed. Run harness checks before Gradle. + +### Phase 3 — Repair build paths + +Switch Docker to the repository-root context, add the root ignore contract, and verify production +and sample images. + +### Phase 4 — Activate Gitea + +Enable repository Actions, register the isolated runner, confirm workflow directory configuration, +and run the preflight workflow. Do not configure required statuses until job names are stable and a +successful run exists. + +### Phase 5 — Enforce merge controls + +Enable the quality `release-gate` and vulnerability status as protected-branch requirements. Seed +negative exercises for a missing required path, public-path drift, forbidden module edge, stale +lockfile, and failed Docker build. + +### Phase 6 — Reassess automation + +Run a real Renovate dependency update with automerge disabled. Re-enable limited automerge only by a +separate human decision backed by the acceptance evidence. + +## 9. Verification Strategy + +1. Mode A hashes match the authoritative export, or Mode B records the human decision, new hashes, + and `controlled-reconstruction` provenance. +2. Harness unit, mutation, schema, renderer, and parity tests pass under the selected mode. +3. Control-plane validator passes on the complete tree and fails on each seeded missing/shadow + mutation. +4. Task-packet resolver emits a stable high-risk CI/deployment packet from the recorded overlay; + the packet and governing-rule checksums verify again at the Task 3 boundary. +5. Gradle wrapper, project discovery, architecture dependency verification, focused ArchUnit, + dependency locks, `test`, and `check` pass. +6. Public-path verification passes with the committed baseline and fails when it is absent or + changed. +7. Production and sample Docker images build from repository-root context. +8. Gitea reports repository Actions enabled and at least one authorized runner online. +9. The preflight and quality fan-in statuses appear on a real pull request. +10. Protected branches reject seeded failures. +11. Renovate config validation and a real dependency update pass without automerge. + +## 10.

Dependency removal must not be mixed with +that recovery because a red baseline cannot distinguish a pre-existing CI failure from a refactoring +regression. + +## 2. Problem Statement + +The module direction is broadly clean, but the declared Gradle graph is wider than the source graph: +many leaves declare every allowed core dependency even when they use only one contract. Pure-core +tests inherit Spring MVC from a global convention. `application-core` imports SLF4J for one outbox +use case and therefore carries the complete Spring Boot starter at compile and runtime. Several +leaves retain unused Groovy, Spock, generated-stub, UUID, or configuration-processor dependencies. + +The existing central ArchUnit suite analyzes whatever happens to be on the +`app-bootstrap` test runtime classpath. Optional leaves are therefore not guaranteed to be analyzed. +The sample-isolation contract also carries a hard-coded subset of modules instead of reading the +19-leaf registry. Locking is strict, but the lock verifier is not a release-gate dependency and +non-BOM version ownership is scattered. + +This design reduces the graph only after characterization, makes topology and architecture coverage +registry-driven, restores pure-core test isolation, and separates application logging intent from +the logging framework. + +## 3. Evidence Classification + +### 3.1 Observed facts + +The following findings are deterministic observations and do not need dependency-removal debate: + +1. `src/settings.gradle` cannot configure without `.harness/project/modules.yaml`. +2. There are exactly 19 leaf `build.gradle` files and 19 leaf `gradle.lockfile` files. +3. No production configuration depends on `:sample-portfolio`; + `app-bootstrap` has one test-only `sampleFixture` edge. +4. The only adapter-to-adapter project edges are: + `messaging`, `cache-redis`, `notification`, and `httpclient` to + `adapter:outbound:support`. +5. `domain-core` and `shared-contract` main source contain no Spring, JPA, Jackson, or SLF4J imports. +6. `application-core` main source contains no Spring import. Its only framework imports are SLF4J in + `PublishPendingOutboxEventsUseCase`. +7. The root build adds Spring Boot test and Spring MVC test starters to every leaf. +8. `cache-redis`, `messaging`, and `notification` have no Groovy tests although their builds apply + Groovy and add Spock. +9. `adapter:outbound:identifier` does not use `uuid-creator`. +10. `src/sample-portfolio/.jqwik-database` is a tracked Java-serialization runtime artifact. +11. `persistence-mongo` owns adapter-local `Example*` domain/document/repository/mapper types and its + repository adapter implements no application/domain port. + +### 3.2 Static candidates + +The following are source-reference candidates, not approved removals. Each must first pass a +leaf-specific compile/test characterization: + +| Leaf | Candidate project edges | +| --- | --- | +| `adapter:inbound:graphql` | `application-core`, `domain-core` | +| `adapter:inbound:grpc` | `application-core`, `domain-core` | +| `adapter:inbound:web` | `domain-core` | +| `adapter:inbound:websocket` | `application-core`, `shared-contract` | +| `adapter:outbound:cache-redis` | `domain-core`, `application-core` | +| `adapter:outbound:httpclient` | `domain-core`, `application-core` | +| `adapter:outbound:identifier` | `domain-core` | +| `adapter:outbound:messaging` | `domain-core` | +| `adapter:outbound:notification` | `domain-core` | +| `adapter:outbound:persistence-jpa` | `domain-core` | +| `adapter:outbound:persistence-mongo` | `application-core`, `shared-contract` | +| `adapter:outbound:support` | `domain-core`, `application-core`, `shared-contract` | + +The same characterization rule applies to these external candidates: + +- GraphQL configuration processor and JSR-310 module. +- gRPC protobuf/stub/annotations dependencies in the no-generated-stub skeleton. +- broad `spring-boot-starter` usage in gRPC, fileserver, and objectstorage. +- explicit Flyway core where the starter already supplies the required API. +- duplicate starter/test declarations in app-bootstrap and sample-portfolio. + +An allowed registry edge is permission, not a requirement to declare that edge. + +## 4. Goals + +1. Keep all module paths and allowed edges in `.harness/project/modules.yaml` only. +2. Make the actual project DAG the smallest graph required by source, tests, and runtime + composition. +3. Preserve the approved outbox failure-reporting refactor's removal of Spring and logging + frameworks from `application-core` compile/runtime classpaths. +4. Give `domain-core`, `application-core`, and `shared-contract` framework-free test conventions. +5. Enforce external dependency purity for core modules from resolved compile/runtime graphs. +6. Analyze every registered production leaf with the architecture suite regardless of runtime + composition. +7. Apply the Spring configuration processor exactly where main source declares + `@ConfigurationProperties`. +8. Verify strict locks in the release gate and assign one owner to every non-BOM version. +9. State which optional adapters are in the default app runtime and which are opt-in. +10. Remove generated jqwik state from source control. +11. Remove the Mongo adapter-local example domain from production without creating a duplicate + sample implementation. + +## 5. Non-Goals + +- No feature behavior, endpoint, persistence schema, or public contract change. +- No conversion to convention plugins, `buildSrc`, an included build, or a version catalog in this + change. Build-logic migration starts only from a green post-refactoring baseline. +- No automatic inclusion of every optional adapter in the production runtime. +- No new Mongo business port or second Mongo sample in `sample-portfolio`. +- No relocation of the shared ThreadLocal implementation in this change. +- No LLM Wiki write as part of this documentation-only design task. + +## 6. Target Topology and Registry Policy + +The registry remains the only topology authority. Every leaf entry must continue to own: + +- stable id +- source path +- Gradle path +- role/family +- allowed project dependencies +- focused command +- nearest module guidance + +Each runtime-capable leaf also receives one explicit runtime membership: + +- `core`: contract/core leaf consumed by registered adapters or bootstrap. +- `app-default`: present on the default `app-bootstrap` runtime classpath. +- `opt-in`: built and architecture-analyzed but absent from the default application runtime. +- `sample-only`: used only by the sample fixture/runtime. +- `composition-root`: `app-bootstrap` or `sample-portfolio` itself. + +The registry validator rejects missing membership, unknown dependency ids, duplicate Gradle paths, +production edges to `sample-portfolio`, adapter peer edges not explicitly allowed by the source +module's `allowed_dependencies`, and cycles. Gradle settings, the project-dependency verifier, +sample-isolation checks, and architecture-analysis classpath all consume this data. No Java test +keeps a copied module list. + +The current default runtime membership is preserved during graph cleanup. Optional adapters do not +become runtime dependencies merely because architecture analysis needs their classes. + +## 7. Approved Application Logging Boundary + +The logging-boundary implementation is owned by +`docs/superpowers/specs/2026-07-25-application-outbox-failure-reporting-design.md` and its matching +implementation plan. That design is a prerequisite for dependency pruning in this plan and is not +redefined here. + +The selected contract is: + +- `application-core` owns `OutboxRelayFailureReportPort`; +- the port has one `report(OutboxRelayFailureReport)` method; +- the safe immutable report carries the approved FAILED/DEAD operational fields and never carries + payload or idempotency data; +- `adapter:outbound:messaging` owns the structured SLF4J reporter implementation; +- `app-bootstrap` injects the port into the manually assembled relay use case; +- application source and dependency guardrails prevent Spring and logging frameworks from returning + to `application-core`. + +Module hygiene begins only after that focused plan is green. This design then verifies the resulting +application dependency purity and removes unrelated static-candidate edges; it does not introduce a +second reporting port or relocate reporter ownership. + +## 8. Test Dependency Conventions + +Test dependencies are role-specific: + +| Role | Baseline | +| --- | --- | +| `domain-core` | JUnit Jupiter API/engine and AssertJ only when tests exist | +| `application-core` | JUnit Jupiter, AssertJ; hand-written fakes; no Spring context | +| `shared-contract` | JUnit Jupiter and AssertJ; no Spring context | +| inbound web/GraphQL/WebSocket/gRPC | transport test modules required by that protocol only | +| persistence adapters | mapping/unit baseline plus datastore Testcontainers only where vendor behavior is tested | +| other outbound adapters | JUnit/Spock selected by actual test language; fake external systems | +| `app-bootstrap` | Spring Boot context/slice support, ArchUnit, and integration-test dependencies | +| `sample-portfolio` | feature, property, slice, and integration-test dependencies owned by the sample | + +The root build may supply JUnit platform launch/runtime configuration, but it must not supply Spring +MVC or Spring context libraries to every leaf. A test dependency belongs in the leaf that uses it. + +## 9. External Dependency Purity Gate + +The logging-boundary plan first introduces `verifyApplicationCoreDependencyPurity`. This refactoring +then replaces that task with the registry-wide `verifyExternalDependencyPurity`; the two tasks do +not remain as overlapping gates. The replacement preserves the application main/test classpath +rules and `:application-core:check` wiring, then resolves each registered leaf's production +`compileClasspath` and `runtimeClasspath` and applies the broader role rules: + +- `domain-core` and `shared-contract`: no external production module at all. +- `application-core`: no Spring, SLF4J/logging backend, JPA/Hibernate, servlet, transport, database, + cloud, or adapter implementation dependency. +- inbound/outbound adapters: no logging implementation dependency; SLF4J API is allowed. +- all production leaves: no test framework on production configurations. + +The task reports `module → configuration → forbidden coordinate → rule`. It checks resolved +coordinates so transitive framework leakage is visible. Existing project-edge verification remains +separate and registry-driven. + +Because the registry and harness API were absent at design time, the exact Python/Groovy/Java +implementation of registry membership, purity/processor gates, and architecture classpath wiring is +written in a post-recovery implementation addendum after the stable task packet is resolved. The +addendum must contain complete code against the recovered API and pass review before any of those +control-plane files are changed. Entry is fail-closed on a concrete overlay, an actual resolver +invocation, matching overlay/packet content hashes, and the resolved rule hash; `--help` output or a +prose-only confirmation is not packet evidence. + +## 10. Registry-Driven Architecture Analysis + +`app-bootstrap` gets an `architectureAnalysis` dependency bucket populated from every registered +production leaf, independent of `app-default` runtime membership. The architecture test runtime +extends this bucket; the application production runtime does not. + +`CleanArchitectureTest` therefore sees GraphQL, gRPC, WebSocket, fileserver, objectstorage, Mongo, +and every other registered leaf. `SampleRemovalSmokeContractTest` reads production module paths from +the same registry instead of its current hard-coded list. + +The architecture configuration is non-consumable and non-resolvable itself; only the dedicated test +runtime is resolvable. This prevents it from being published or accidentally used by `bootJar`. + +## 11. Configuration Processor Consistency + +The rule is mechanical: + +- a leaf with main-source `@ConfigurationProperties` declares + `annotationProcessor 'org.springframework.boot:spring-boot-configuration-processor'`; +- a leaf without it does not. + +A verification task scans registered main source roots and compares the result with the declared +annotation-processor dependency. This removes the unused GraphQL processor and adds missing +processors to settings-owning leaves without relying on a copied module list. + +Binding/validation tests remain required for every settings class; generated metadata is not a +substitute for behavior tests. The post-recovery control-plane addendum inventories that mapping and +contains complete focused test code for every uncovered class before processor declarations change. + +## 12. Runtime Composition and Component Scanning + +`app-bootstrap` keeps only registry members marked `app-default` on its production runtime. +`opt-in` modules remain independently buildable and architecture-analyzed. Adoption of an opt-in +module is an explicit registry and composition-root change with its own focused tests. + +`CaSkeletonApplication` narrows component and configuration-properties scanning to: + +- `dev.caskeleton.bootstrap` +- `dev.caskeleton.adapter` + +It removes `dev.caskeleton.application`, `dev.caskeleton.domain`, and `dev.caskeleton.shared` from +both scans. Those core packages own no Spring component or configuration-properties class, and the +outbox use case remains manually composed. A context test pins this boundary. + +This is the smallest safe scan change in this refactoring. Converting all adapter configuration to +explicit `@Import` or auto-configuration is a separate design change. + +## 13. Leaf-Specific Cleanup + +All 19 leaves receive a characterization record and focused command: + +| Leaf | Target decision | +| --- | --- | +| `domain-core` | preserve zero-framework main; isolate pure tests | +| `application-core` | consume the approved outbox-reporting result; verify Boot/SLF4J remain absent | +| `shared-contract` | preserve stdlib-only production graph | +| `adapter:inbound:web` | remove only compile-proven unused core edge; retain transport dependencies | +| `adapter:inbound:graphql` | remove compile-proven core/tooling candidates | +| `adapter:inbound:grpc` | retain server/health/reflection runtime; remove no-stub candidates only after compile | +| `adapter:inbound:websocket` | retain domain-event and WebSocket dependencies; prune unused core edges | +| `adapter:outbound:support` | retain only compile-proven core edges and SLF4J API/autoconfigure | +| `adapter:outbound:cache-redis` | remove unused core edges and unused Groovy/Spock | +| `adapter:outbound:fileserver` | keep application/shared ports; narrow starter only after characterization | +| `adapter:outbound:httpclient` | keep shared/support and actual Groovy/Spock tests; prune unused core edges | +| `adapter:outbound:identifier` | keep application pseudonymizer port; remove unused domain/uuid-creator | +| `adapter:outbound:messaging` | retain the approved outbox reporter plus application/shared/support; remove unused domain and Groovy/Spock | +| `adapter:outbound:notification` | keep application/shared/support; remove unused domain and Groovy/Spock | +| `adapter:outbound:objectstorage` | keep application/shared/AWS SDK; narrow starter only after characterization | +| `adapter:outbound:persistence-jpa` | keep application/shared/JPA/vendor runtime; test domain/Flyway candidates | +| `adapter:outbound:persistence-mongo` | remove all adapter-local `Example*` types/tests; keep generic opt-in config/properties and binding/disabled-mode tests; remove application/shared edges | +| `app-bootstrap` | preserve composition role; separate architecture classpath; narrow scans and duplicate tests | +| `sample-portfolio` | preserve fixture-only isolation; remove generated jqwik state and own sample-only dependencies | + +## 14. Generated jqwik State + +`src/sample-portfolio/.jqwik-database` is deleted from version control. +`src/.gitignore` ignores `.jqwik-database` at any module working directory. Property tests remain +deterministic from committed seeds/configuration rather than a developer-machine serialization +cache. + +## 15. Shared ThreadLocal Decision + +`ThreadLocalDomainContextPropagator` and `DomainContextPropagatorFactory` stay in +`shared-contract` for this refactoring. They are Java-stdlib-only operational infrastructure, and +moving them changes concurrency composition rather than dependency hygiene. + +This is a deliberate secondary decision, not an accidental omission. The purity gate pins their +zero-external-dependency status. Relocation to bootstrap or an adapter requires a separate design +with virtual-thread/context-propagation characterization and is not bundled into graph cleanup. + +## 16. Persistence Mongo Decision + +The production Mongo leaf removes: + +- `ExampleRecord` +- `ExampleMongoDocument` +- `ExampleMongoMapper` +- `ExampleMongoRepository` +- `ExampleMongoRepositoryAdapter` +- their example mapping/repository tests + +`MongoPersistenceConfig` and `MongoPersistenceProperties` remain as generic opt-in Spring Mongo +machinery. Tests cover properties binding, disabled-by-default behavior, and mock-backed +enabled-mode creation of one Boot 4 `MongoClient` and `MongoTemplate` without a network connection +or sample repository. + +No duplicate Mongo domain is added to `sample-portfolio`; the WorkLog JPA sample remains the sole +reference business domain. The Mongo leaf then removes its unused application/shared project edges. + +## 17. Locking and Version Ownership + +After each leaf cleanup: + +1. run its compile and focused test; +2. regenerate its lock state through the repository `resolveAndLockAll --write-locks` entrypoint; +3. run `verifyDependencyLocks`; +4. inspect that removed coordinates disappeared from production configurations. + +`check` or the CI release gate invokes `verifyDependencyLocks`. Spring Boot BOM owns managed Spring, +Jackson, Micrometer, Testcontainers, and related versions. Existing root extension values own gRPC, +protobuf, and AWS BOM versions. Every remaining non-BOM direct version has one root-level owner. + +The build remains Groovy DSL with the current root configuration during this work. A version catalog +or convention-plugin migration is considered only after the complete refactoring and full `check` +are green, so build-system migration cannot mask dependency-removal regressions. + +## 18. Verification Strategy + +Verification proceeds from narrow to broad: + +1. CI/harness prerequisite commands. +2. Registry schema, cycle, membership, and 19-leaf parity tests. +3. Before/after dependency reports for each candidate leaf. +4. Leaf `compileJava`, focused test, and configuration-processor check. +5. Pure-core external dependency gate. +6. Registry-driven project dependency and architecture tests. +7. Sample-off and optional-runtime composition tests. +8. Dependency lock verification. +9. Full `test` and `check`. + +No removal is accepted when a focused command is skipped without a named environmental reason and +recorded residual risk. + +## 19.

Duplicate test declarations may be removed +only when the focused test classpath continues to compile and execute. + +## 5. Pure-core test and verification policy + +`domain-core`, `application-core`, and `shared-contract` receive only JUnit Jupiter, AssertJ, and +the JUnit launcher from the root convention. All other leaves keep the existing Spring test +baseline in this change; family-wide convention plugins are out of scope. + +The existing application dependency-purity gate remains. A new registry-driven configuration +processor parity gate applies this Boolean invariant to every leaf and is wired into `check`: +main source contains one or more exact `@ConfigurationProperties(` occurrences if and only if the +leaf `build.gradle` contains exactly one Spring configuration-processor declaration. It must ignore +`@ConfigurationPropertiesScan`; the number of settings classes is not compared with the number of +processor declarations. + +## 6. Spring Boot 4 compatibility + +The web adapter changes +`org.springdoc:springdoc-openapi-starter-webmvc-api:2.8.6` to `3.0.0`, the first stable +springdoc line released for Spring Boot 4.0.0. The existing sample tests that boot a real server +and call `/v3/api-docs` are the behavior gate. Snapshot changes are accepted only if they are a +deterministic library-version result and retain the public API contract. + +Springdoc 3 otherwise widens `ApiError.details` from the committed `type: object` to an +unconstrained OAS 3.1 schema. A web-adapter-owned `OpenApiCustomizer` must restore the object schema +in the final generated document. Both real-server test applications import that production +configuration. `shared-contract` remains free of Swagger annotations and dependencies. + +GraphQL and WebSocket remove direct `com.fasterxml.jackson` declarations because neither source +set imports them and Spring Boot 4 owns its JSON stack through the relevant starters. +The web adapter retains the `JsonNullable` value type, but its `0.2.6` artifact also declares +Jackson 2 transitively while this repository supplies explicit Jackson 3 serializers. Before and +after dependency insight plus focused present/null/undefined serialization tests determine whether +that transitive edge can be excluded. Exclusion is applied only if those tests and the real-server +OpenAPI tests pass; springdoc/Swagger's independently required JSON graph is not removed by +assumption. + +## 7. Mongo production boundary + +Delete the adapter-local `ExampleRecord`, document, mapper, repository, repository adapter, and +their tests. `MongoPersistenceConfig` remains conditional on +`ca-skeleton.persistence-mongo.enabled=true` and explicitly imports the Mongo client/data +auto-configurations without owning a fake business repository. + +The starter also registers Mongo auto-configuration directly through Boot metadata, independently +of `MongoPersistenceConfig`. A module-level `AutoConfigurationImportFilter`, registered through +Boot 4's `META-INF/spring.factories` discovery path, must exclude the Boot 4 sync/reactive client, +data, repository, health, and metrics Mongo auto-configurations while the enable property is absent +or false. It must allow them unchanged when the property is true; consumers must not need to set +`spring.autoconfigure.exclude`. + +Replacement tests must prove: + +- an actual `@EnableAutoConfiguration` context in default/false mode creates no Mongo + infrastructure; +- properties bind the enable flag; +- enabled mode can create the infrastructure with a supplied mock `MongoClient`, without a real + network connection; +- production source contains no `Example*` type. + +The Testcontainers dependencies leave this module when the example repository IT is removed. + +## 8. Correlation context boundary + +`application-core` owns a framework-free `CorrelationIdPort` whose read result is optional. +`adapter:inbound:web` implements it from the sanitized request MDC correlation key. +`CreateWorkLogUseCase` and `PosterEventPublisher` depend only on the port and preserve the current +fallback to the generated event id when no correlation id exists. + +Tests first pin present/blank/absent behavior and prove the sample application packages no longer +import SLF4J/MDC. Diagnostic storage remains an adapter concern. + +## 9. Runtime composition and generated state + +`app-bootstrap` keeps its current default runtime modules. Its build description and README must +state that optional leaves require an explicit registry and composition-root dependency change. +Optional adapters remain independently buildable and testable. + +The tracked four-byte `src/sample-portfolio/.jqwik-database` is generated runtime state. Delete it +and add `.jqwik-database` to `src/.gitignore`; retain jqwik itself because property tests use it. + +## 10.

Executive decision + +This repository should evolve from a collection of integration seams into an **opt-in production +capability platform**. + +The target is not to enable Redis, Kafka, MongoDB, sessions, CDC, and every transport in every +application. The target is: + +1. a developer selects a capability and provider by typed configuration; +2. the composition root validates the selected topology and guarantees at startup; +3. application code depends only on semantic, framework-free ports; +4. the selected adapter supplies a real client, bounded defaults, health, metrics, failure + semantics, and reusable contract tests; +5. unused capabilities create no connection, background worker, schema, or implicit runtime + behavior; +6. advanced strategies remain available without pretending that one strategy is correct for every + domain. + +The default template remains light. Production capability packs are **available by default but +inactive by default**. A capability is not called production-ready merely because a class or client +seam exists. + +### Primary decisions + +- Keep `domain-core`, `application-core`, and `shared-contract` free of Spring, Redis, Kafka, + persistence, transport, and observability SDK types. +- Put use-case-owned semantic ports and application policies in `application-core`; put + skeleton-wide transport/operational contracts in `shared-contract`; put provider selection and + Spring composition in `app-bootstrap`. +- Initially preserve the registered 19-leaf topology. Expand the existing technology leaves in + cohesive packages and split a leaf only when inbound/outbound direction or independent lifecycle + requires it. +- Treat `adapter:outbound:cache-redis` as the first Redis technology capability provider, but never + reuse cache's fail-open behavior for sessions, idempotency, locks, or strict rate limits. +- Add a future `adapter:inbound:messaging-kafka` leaf before implementing Kafka consumers. A + consumer is a driving adapter and does not belong in the existing outbound producer leaf. +- Keep an outbox append operation in the same source-of-truth datastore transaction as the business + write. Make the **dispatch mechanism** selectable: polling or CDC. +- Define end-to-end messaging as at-least-once delivery plus idempotent consumers/inbox. Do not + advertise generic exactly-once delivery across a database and broker. +- Separate evictable cache data from correctness-sensitive Redis data at the Redis deployment or + cluster level, not only by key prefix or database number. +- Provide capability-level safe operations and versioned Lua scripts. Do not expose a general + `RedisTemplate`, Kafka producer, HTTP client, or cloud SDK to use cases. + +## 2. Scope and non-goals + +This design covers: + +- Redis cache, rate limiting, sessions, idempotency, locks, and reusable atomic operations; +- polling and CDC outbox, Kafka producer/consumer, inbox, delivery semantics, and query/read models; +- file server, object storage, HTTP client, notification, JPA, MongoDB, web, GraphQL, gRPC, and + WebSocket production baselines; +- provider selection, typed settings, health, observability, Gradle ownership, and test strategy; +- a phased path from the current skeleton to an operational baseline. + +This design intentionally does not: + +- select one infrastructure topology for every future product; +- invent domain-specific throughput or latency numbers; +- claim benchmark improvements without a real workload and environment; +- make every optional dependency active in the default application; +- promise cross-store atomicity, generic exactly-once processing, or strong consistency from a + Redis lock; +- place example business concepts in production modules; +- create a universal repository, universal query DSL, or a raw infrastructure facade in + `application-core`. + +## 3.

A stale caller can overwrite or delete a reclaimed record. +- The multi-instance startup validator checks bean names, not capability types or guarantees. Its + test accepts plain `Object` beans, so it can report safety without a working distributed + implementation. +- The current outbox row is mutated through `PENDING/IN_FLIGHT/PUBLISHED/...`. Debezium's standard + Outbox Event Router expects the outbox event source to behave as an insert-only queue, so CDC + cannot be attached to the current mutable design without a schema/behavior split. +- The current authenticated rate-limit key lacks a route or policy dimension, while the + unauthenticated key includes the route. This makes policy isolation inconsistent. +- Blanket `catch (Exception)` cache fail-open behavior can hide codec or programming defects as + ordinary cache misses. +- Merely composing every existing leaf is unsafe: GraphQL and WebSocket lack a uniform module + enable gate, gRPC defaults include plaintext/reflection behavior, and filesystem object storage + can activate through a missing-property default. +- The HTTP decorator order currently lets the circuit breaker observe a complete retry bundle, + while its documentation says each attempt is counted. The declared global call timeout also + does not actively cancel an already-running attempt. + +## 4. Alternatives considered + +### A. One large infrastructure starter in `app-bootstrap` + +This is rejected. It would make classpath presence activate too much auto-configuration, blur +provider ownership, and turn the composition root into an infrastructure implementation module. + +### B. A new Gradle leaf for every capability-provider pair + +Examples would be `cache-redis`, `lock-redis`, `session-redis`, `idempotency-redis`, and +`rate-limit-redis`. This has the cleanest physical isolation but creates module and connection +configuration duplication immediately. It also changes the exact 19-leaf registry before the +semantic contracts are stable. + +This becomes appropriate only when a provider has an independent release cadence, security +boundary, deployment lifecycle, or dependency graph. + +### C. Semantic ports plus existing technology leaves + +This is the selected first-stage design. + +- `application-core` owns semantic ports and framework-free orchestration. +- existing adapter leaves own actual SDKs and provider-specific behavior; +- `app-bootstrap` selects exactly one provider per required capability; +- provider packages use separate failure policies even when they share a client library; +- module splits are made only for direction or lifecycle reasons. + +The known compromise is the `cache-redis` module name. Its short-term responsibility becomes Redis +technology capabilities, while a rename to `adapter:outbound:redis` is deferred to a separately +approved module-registry migration. + +### D. Extract an external platform BOM/starter repository now + +This is deferred. Extraction before the contracts and test kits are proven would freeze immature +APIs and make local architecture verification harder. A later extraction may publish provider +artifacts and a BOM after at least two real consumers validate the contracts. + +## 5.

A `SessionControlPort` is added only if an application use +case must revoke a user's sessions, enforce a business-driven concurrent-session rule, or audit +session control. + +## 6. Capability readiness model + +Each capability has a visible readiness level: + +| Level | Meaning | Required evidence | +| --- | --- | --- | +| R0 Contract | Type, seam, or placeholder only | unit tests and architecture boundary | +| R1 Local | Works in one local process or local service | focused integration test and documented limitations | +| R2 Production baseline | Real provider, safe configuration, failure semantics, health, metrics, security, graceful lifecycle | provider contract, real-service integration, concurrency/failure tests, runbook | +| R3 Scale/HA | Cluster/failover/rolling-upgrade behavior is proven | topology tests, compatibility matrix, recovery and capacity runbooks | + +The current repository contains a mixture of R0, R1, and partial R2 components. Documentation and +startup diagnostics must not label an R0 seam as an R2 provider. + +Every capability receives a "capability card" containing: + +- owner module and semantic port; +- provider IDs and readiness level; +- guarantee and explicit non-guarantees; +- default failure mode and allowed overrides; +- required topology and persistence/eviction policy; +- configuration and secrets; +- liveness/readiness impact; +- bounded-cardinality metrics and trace spans; +- fit/non-fit guidance, cost model, and resource bounds; +- common unsafe recipes, the race/failure they create, and the safe replacement; +- focused, integration, and failure-test commands; +- rolling-upgrade and recovery notes; +- runbook links. + +This is how the template teaches operational depth without forcing every project to use every +feature. R2 examples are executable contract examples, not copy-only snippets: a provider must +prove its documented concurrency and failure semantics before the card can claim the guarantee. + +## 7. Provider selection and configuration + +Provider selection becomes explicit per capability. `multi-instance-enabled` remains descriptive +runtime context, not an implicit provider selector. + +`provider: disabled | <provider-id>` is the activation SSOT for a selectable capability. A binding +map uses `disabled | <provider-id>` per binding, and a mode capability such as outbox uses +`dispatch-mode: disabled | polling | cdc`. A leaf-level `enabled` flag exists only when there is no +provider or mode axis. If a legacy flag is temporarily retained, any disagreement with the SSOT is +a startup error. + +`matchIfMissing=true`, classpath presence, or a local-provider default must never activate a +production capability.

Redis capability design + +The Redis summary in this section is expanded and governed by +[Redis Production Capability Deep Design](2026-07-26-redis-production-capability-design.md). That +document fixes the application contracts, role/deployment isolation, key and codec schemas, +versioned Function/Lua catalog, cache strategies, rate-limit algorithms, lease/fencing and +idempotency state machines, session profile, client backpressure, security, observability, and +topology/failure CI in implementation-ready detail. + +### 8.1 Runtime role isolation + +At minimum, Redis is modeled as three roles: + +| Role | Data | Eviction/durability expectation | Typical failure semantics | +| --- | --- | --- | --- | +| `cache` | recomputable values, negative entries, soft locks | bounded memory, an `allkeys-*` policy selected by operations | usually fail open | +| `coordination` | idempotency, locks, strict quotas, fencing counters | `noeviction`, HA, persistence/capacity alarms | usually fail closed | +| `session` | authenticated sessions and indexes | `noeviction`, HA, serializer compatibility, persistence | fail closed | + +A Redis database number or key prefix does not isolate `maxmemory`, eviction, failover, or noisy +neighbors. Production settings require separate managed databases, clusters, or instances where +these guarantees differ. + +Each role has typed endpoint/topology/TLS/ACL/timeout/pool/topology-refresh settings and its own +health component. Application code never issues `CONFIG SET`; deployment configuration owns +`maxmemory`, eviction, persistence, and replica policy. + +### 8.2 Safe operation catalog + +The Redis leaf provides reusable, capability-oriented operations: + +| Category | Baseline operations | +| --- | --- | +| Cache | get, multi-get, put with bounded TTL, put-if-absent, evict, multi-evict, touch, namespace-generation bump | +| Atomic primitives | set-if-absent-with-TTL, compare-and-delete, compare-and-expire, increment-with-initial-TTL | +| Rate limit | fixed window, sliding counter, token bucket; sliding log and GCRA opt-in | +| Idempotency | atomic claim, renew, complete, release with owner token | +| Lock | acquire, owner-safe renew/release, optional atomic fencing counter | +| Streaming/invalidation | bounded Redis Streams or Pub/Sub helpers only inside messaging/cache adapters | + +These are adapter utilities, not use-case APIs. Raw list/set/hash commands remain available to a new +adapter implementation through the client library, but are not promoted as a stable application +contract. + +Every packaged script has a `ScriptDescriptor`: + +- stable name and semantic version; +- source checksum; +- key count and cluster-slot rule; +- argument/result schema; +- complexity and maximum collection size; +- timeout/failure behavior; +- metrics name; +- compatible Redis versions. + +Every public helper also has an operation contract that states atomicity scope, command/script +complexity, worst-case state growth, cluster-slot constraints, clock source, retry safety, and +failure result. Its documentation pairs the common unsafe multi-command recipe with the packaged +atomic replacement, and its provider contract contains a concurrent race test. This makes the +reason for Lua or another primitive visible to a developer instead of presenting a magic helper. + +### 8.3 Why Redis single-threading does not remove races + +An individual Redis command is serialized, but a client sequence such as: + +```text +GET -> decide -> INCR -> EXPIRE +``` + +is not one command. Other clients can interleave between its steps. The `INCR` may succeed while +`EXPIRE` is skipped after a client failure, or two clients can both make a decision from stale +state. + +Lua scripts solve the read/decide/write atomicity problem by running as one atomic server-side +operation. They introduce another risk: Redis blocks other work while a script runs. Therefore: + +- scripts are O(1) or strictly bounded; +- no unbounded loop, `KEYS`, large collection scan, network, filesystem, or dynamic code; +- keys are declared through `KEYS[]`; +- multi-key scripts use a common, narrow hash tag such as a resource hash, not a whole-tenant hot + slot; +- time arithmetic uses integer milliseconds and a documented clock source; +- scripts are classpath resources, not concatenated strings; +- the client uses cached execution (`EVALSHA`) with safe reload on `NOSCRIPT`; +- Redis Functions are an opt-in deployment mode only when function installation/version ownership + is available; +- slow-script, command-timeout, pool, and server-latency signals are monitored. + +### 8.4 Cache contract and strategies + +The current `String get/put` API is replaced by an application-owned cache contract that separates: + +- `HIT`, `MISS`, `NEGATIVE_HIT`, and `DEGRADED`; +- region and key from backend provider; +- payload schema/version from Redis serialization; +- positive TTL, negative TTL, soft TTL, and hard TTL; +- backend failure from codec/programming failure. + +The Redis adapter stores an opaque, versioned payload. A framework-free `CacheCodec<T>` and +`CacheAsideExecutor<T>` keep domain/application values type-safe without allowing the Redis adapter +to serialize arbitrary domain objects by reflection. JDK native serialization is forbidden. + +Baseline strategies: + +- cache-aside; +- after-commit invalidation, with eviction preferred over blind cache update; +- bounded positive/negative TTL; +- TTL jitter; +- process-local single-flight; +- versioned key namespace; +- payload size limit; +- batched `SCAN` plus `UNLINK` for operator cleanup, never regular `KEYS`; +- low-cardinality hit/miss/error/load metrics. + +Opt-in strategies: + +- stale-while-revalidate with soft/hard TTL; +- refresh-ahead; +- probabilistic early refresh; +- L1 local plus L2 Redis; +- distributed stampede suppression with double-check and bounded soft lock; +- client-side tracking or Pub/Sub invalidation; +- compression above a configured threshold; +- generation-based mass invalidation. + +Write-through cannot imply atomic DB+Redis commit. Write-behind is not an in-memory executor behind +the cache API; it requires a durable outbox/stream consumer and its own retry/DLT semantics. +Pub/Sub invalidation is best effort, so TTL and schema version remain the recovery boundary. + +### 8.5 Rate-limit strategy registry + +Transport adapters resolve principal, tenant, API key, IP, route, and policy, then invoke the +framework-neutral `EdgeRateLimitContract` from `shared-contract`. The Redis provider implements +that contract and `app-bootstrap` wires the edge; `application-core` is not involved unless a +separate business quota is part of a use case. The contract receives only an opaque hashed subject +and policy: + +```text +RateLimitRequest(policyId, subjectHash, cost) + -> RateLimitDecision(allowed, remaining, retryAfter, resetAt) +``` + +The stable key dimensions are: + +```text +environment + policyId + tenant? + subjectHash +``` + +Raw PII, token, request body, and full URL are forbidden in Redis keys, logs, traces, and metric +tags. + +| Algorithm | Operational characteristic | Availability | +| --- | --- | --- | +| Fixed window | O(1), simple, permits boundary burst | local/R1 and Redis/R2 | +| Sliding-window log | exact but one sorted-set member per event; memory/CPU grows with volume | advanced opt-in | +| Sliding-window counter | approximate sliding window with bounded O(1) state | production option | +| Token bucket | independently controls average rate and burst capacity | recommended Redis default | +| Leaky bucket | smooth output; synchronous HTTP request queueing is not allowed | background/workflow opt-in | +| GCRA | precise smoothing with compact state | advanced opt-in | + +Policies are selected by stable `policyId`, not a global algorithm. A policy declares algorithm, +capacity/rate/window, burst, cost, failure mode, and subject dimensions. `Retry-After` comes from +the decision rather than the current fixed one-second value. + +When Redis fails, an optional emergency limiter is conservative, process-local, bounded in size and +TTL, and emits a degraded signal. It is not described as globally accurate. + +### 8.6 Session profile + +Authentication modes are exclusive: + +```text +jwt | redis-session +``` + +JWT remains the default: + +- stateless resource server; +- no session repository; +- CSRF may remain disabled for bearer-only APIs; +- Redis failure does not affect authentication. + +`redis-session` is opt-in: + +- real Spring Session Redis implementation on the separate session role; +- `IF_REQUIRED` session creation; +- CSRF enabled and tested; +- `Secure`, `HttpOnly`, `SameSite`, path/domain, expiry, and session-id rotation settings; +- logout deletes the server session; +- explicit serializer with versioning and allowed types; no JDK serialization; +- rolling-deploy compatibility test; +- multi-pod read/touch/expiry/logout contract; +- fail-closed repository behavior and readiness inclusion; +- optional indexed repository only when principal lookup/concurrent-session control is required. + +Login endpoints and identity proofing remain product decisions. The capability pack provides secure +session storage and web-security composition, not a guessed login business flow. + +### 8.7 Redis health and telemetry + +Required bounded metrics include: + +- cache get/load/invalidate outcome and duration by logical region; +- rate-limit decision/fallback by policy and algorithm; +- idempotency claim/replay/conflict/takeover/store operation; +- lock acquire/renew/lease-lost/release/fencing rejection; +- session repository operation/expiry/error; +- Redis command latency, timeout, connection pool saturation, reconnect, and server memory/eviction. + +No cache key, user, tenant, session ID, message ID, or lock resource is a metric tag. + +## 9. Idempotency design + +The current `find -> tryBegin` and scope-only completion API becomes one atomic ownership protocol: + +```text +claim(request) + -> ACQUIRED(ownerToken, leaseUntil) + -> REPLAY(storedResponse, replayUntil) + -> IN_PROGRESS(retryAfter) + -> FINGERPRINT_MISMATCH +``` + +Follow-up operations: + +```text +renew(ownerToken, newLeaseUntil) +complete(ownerToken, response, replayUntil) +release(ownerToken) +``` + +Rules: + +- execution lease and completed-response replay TTL are separate; +- completion and release compare the owner token; +- stale-owner operations return ownership-lost and cannot mutate a new claim; +- fingerprint canonicalization/version is explicit; +- stored response size, encryption/PII, codec version, and allowed replay metadata are bounded; +- mutations fail closed when the idempotency store is unavailable; +- JPA and Redis providers run the same contract suite; +- the sample module must demonstrate a POST genuinely invoking the executor rather than only + accepting an unused header. + +Guarantees are declared: + +- `REQUEST_REPLAY`: suppresses concurrent/repeated request execution as far as the store protocol + can observe; +- `SAME_STORE_TRANSACTIONAL`: the idempotency record and business change commit in the same + datastore transaction; +- `EXTERNAL_IDEMPOTENCY`: an outbound provider also receives a stable idempotency key. + +A Redis claim plus a JDBC business write is not `SAME_STORE_TRANSACTIONAL`. A crash after the +business write and before Redis completion can cause replayed execution. DB constraints, +intrinsically idempotent commands, outbox, compensation, or downstream idempotency keys remain +necessary. + +## 10. Lock and coordination design + +One mutex interface should not impersonate every coordination primitive. + +| Contract | Purpose | Correctness expectation | +| --- | --- | --- | +| `DistributedLockPort` / future `DistributedMutexPort` | reduce duplicate work or contention | efficiency only; DB constraints/invariants remain authoritative | +| `FencedLockPort` | prevent stale holders from writing | protected resource must reject lower fencing tokens | +| `LeaderElectionPort` | select an active coordinator | explicit leadership/lease lifecycle | +| `SemaphorePort` | bound distributed concurrency | permit ownership and expiry | +| `WorkClaimPort` | claim queue/jobs | claim token and visibility timeout | + +A Redis lease uses: + +- `SET key ownerToken NX PX lease`; +- owner-checked renew and release Lua scripts; +- bounded acquisition retry with jitter; +- maximum hold duration and bounded renewal count; +- lease-lost signal; +- idempotent release; +- optional atomic monotonically increasing fencing counter in the same cluster slot. + +Blind `DEL` is forbidden. An unlimited watchdog is forbidden. Fencing is useful only if the +database, object store, or downstream write port stores and rejects stale tokens. + +The fencing counter is separate from the expiring lease and never expires or resets. The protected +resource rejects a token lower than its accepted high watermark. Equality is accepted only for the +same owner token and lease epoch; a different owner must present a strictly greater token. If Redis +failover can lose an acknowledged increment, this provider cannot claim an R2 correctness +guarantee: acquisition fails closed/unready until a monotonic epoch above the protected resource's +recorded high watermark is established. A lock plus a best-effort Redis counter is still only an +efficiency mechanism. + +Provider guidance: + +- local provider: development/single-node only; +- JDBC table/advisory provider: low-rate coordination close to the primary DB; +- Redis provider: low-latency coordination with explicit failover limitations; +- a consensus system may be added later for stronger lease/election requirements; +- Kafka partition ownership is a work-distribution mechanism, not a generic mutex. + +Redis/Redlock is not advertised as a strong correctness guarantee. Network partitions, failover, +lease expiry, pauses, and wall-clock behavior require fencing or an authoritative invariant. + +## 11. Outbox, CDC, messaging, and inbox design + +### 11.1 What can and cannot be provider-neutral + +The outbox append must share the source-of-truth transaction: + +- a JPA/PostgreSQL business write appends to PostgreSQL; +- a Mongo business write appends to Mongo in the same supported transaction; +- moving the append to Redis or Kafka would lose atomicity unless a real distributed transaction is + introduced. + +The dispatch strategy is selectable: + +```text +disabled | polling | cdc +``` + +### 11.2 Immutable event plus delivery state + +Split the current mutable row: + +```text +outbox_event + immutable event envelope + +outbox_delivery + polling-only claim and delivery state +``` + +`outbox_event` contains: + +- event/message ID; +- event type and schema version; +- aggregate type, aggregate ID, and aggregate sequence/version; +- logical destination and partition key; +- content type and payload; +- occurred-at time; +- tenant when active; +- correlation and causation IDs; +- trace context allowlist. + +Physical Kafka topic names are adapter configuration. Application event types do not become topic +names by convention. + +Polling mode writes both rows in the business transaction and mutates only `outbox_delivery`. +Polling retains current short claim transactions, broker publish outside the DB transaction, +retry/backoff, aggregate ordering, orphan reclaim, and dead-letter behavior, with these additions: + +- claim owner token on every state transition; +- aggregate sequence rather than timestamp-only order; +- broker acknowledgement deadline; +- one combined retry budget across broker client and relay; +- operator replay/requeue/skip tooling and audit; +- explicit resolution for a dead event that blocks aggregate ordering. + +CDC mode: + +- writes only the immutable event row; +- does not create the Java polling scheduler or polling publisher; +- uses an externally deployed Kafka Connect/Debezium connector and Outbox Event Router; +- routes event ID to a header and aggregate/partition key to the broker key; +- owns connector predicate, schema mapping, offset, snapshot, WAL/replication-slot, retention, + restart, and recovery configuration; +- monitors connector lag, retained WAL, offset progress, serialization errors, and restarts; +- does not reuse polling `PUBLISHED` status or polling lag metrics. + +`outbox_event` is time/range partitioned for bounded retention. Cleanup may purge only a closed +partition whose high watermark is proven consumed by the connector checkpoint and whose replay +retention has elapsed. Cleanup never updates event rows, explicitly filters any cleanup +delete/tombstone records, alarms on table/partition growth, and is tested across connector outage, +restart, and snapshot cutover. + +Polling and CDC dispatch are mutually exclusive. Switching modes requires a runbook covering write +freeze or dual-read avoidance, backlog drain, connector offset verification, and rollback. + +### 11.3 Kafka producer baseline + +The messaging leaf gains a real client/provider: + +- acknowledgement-aware send result; +- `acks=all` and idempotent producer configuration; +- bounded delivery timeout and retry budget; +- stable key/partition ordering; +- compression/batch limits; +- TLS/SASL and secret references; +- schema serializer and compatibility validation; +- low-cardinality metrics and OTel propagation; +- readiness for required producer paths; +- graceful flush and shutdown. + +Kafka producer transactions are used only for Kafka-native workflows where their boundary applies, +such as consume-process-produce with committed offsets. They do not make a database write and Kafka +publish one atomic transaction. + +Best-effort `MessagePublisher` remains explicitly named and documented as best effort. Durable +business events use outbox. + +### 11.4 Kafka consumer and inbox + +Before consumer implementation, add an `adapter:inbound:messaging-kafka` leaf through the registry +migration workflow. Its production baseline includes: + +- manual acknowledgement after application success; +- handler/schema/version allowlist; +- bounded concurrency and queues; +- pause/resume backpressure; +- rebalance and `max.poll` handling; +- bounded retry topic or delayed-retry strategy; +- poison/deserialization failure classification; +- DLT plus audited replay tooling; +- trace context restoration; +- graceful drain and shutdown; +- consumer lag/rebalance/retry/DLT metrics. + +`InboxStorePort` scope is: + +```text +consumerGroup + handlerName + tenant? + messageId +``` + +For a handler that writes a database, inbox claim/completion and the business write commit in the +same database transaction. A Redis inbox may be a fast prefilter or serve a DB-free handler, but it +cannot claim same-store atomicity for a JDBC or Mongo write. + +End-to-end wording is: + +```text +at-least-once delivery + idempotent consumer/inbox +``` + +Redis Streams may be offered later as a smaller-scale messaging provider with consumer-group, +pending-entry, reclaim, trim, and dedupe contracts. It is not treated as a drop-in Kafka clone. + +## 12. Query and persistence design + +### 12.1 Query progression + +Keep feature-specific `*QueryPort` interfaces. Do not add one universal `QueryPort<Q, R>` or generic +repository. + +Supported progression: + +1. same-store aggregate read; +2. same-store projection via JPQL/JdbcTemplate/Mongo projection; +3. primary/read-replica routing; +4. separate read model populated through Kafka/CDC; +5. purpose-specific search or analytical store. + +Common application values: + +- opaque, signed, versioned cursor; +- bounded page size; +- allowlisted sort/filter; +- `ReadConsistency` such as `STRONG`, `READ_YOUR_WRITES`, `BOUNDED_STALENESS`, `EVENTUAL`; +- projection checkpoint and lag. + +`TransactionPort.inRead()` does not silently mean "use a replica." The query's consistency policy +and request context select primary or replica. Read-after-write flows remain on primary unless a +causal/checkpoint contract proves otherwise. + +### 12.2 JPA/PostgreSQL production baseline + +Preserve: + +- OSIV disabled; +- application-owned transaction port; +- Flyway migrations; +- persistence exception translation; +- current polling outbox, idempotency, and JDBC lock providers as selectable providers. + +Add: + +- explicit pool sizing, acquisition timeout, leak detection policy, and shutdown; +- statement/query/lock timeout hierarchy within the request deadline; +- batch write and fetch-size settings; +- N+1 detection and representative query-plan tests; +- optimistic version and bounded pessimistic-lock use; +- primary/read-replica routing with explicit consistency; +- migration expand/contract and rollback/roll-forward rules; +- tenant filter/index/unique-constraint rules when tenancy is active; +- slow query and pool saturation metrics; +- same-store inbox implementation; +- provider packages that make PostgreSQL-specific SQL visible and tested. + +Database-backed outbox/idempotency/lock remain valid providers. They stop being the only providers. + +### 12.3 MongoDB production baseline + +The Mongo leaf remains free of example business documents and gains reusable infrastructure: + +- typed URI/topology/TLS/credential/timeout/pool settings; +- explicit read preference, read concern, write concern, and transaction options; +- replica-set/sharded-cluster requirement validation for transactions/change streams; +- index manifest, unique/TTL indexes, drift detection, and migration runner; +- schema validation and optimistic versioning guidance; +- bounded query/page/time limits; +- retryable read/write classification; +- change-stream resume token/checkpoint store and oplog-window monitoring; +- same-store Mongo outbox/inbox option; +- real replica-set Testcontainers contract; +- rolling serializer/schema compatibility. + +Change streams are resumable only while the required oplog history and compatible pipeline/options +remain available. Pool sizing accounts for long-lived change-stream cursors. + +## 13. Remaining outbound capability baselines + +### 13.1 HTTP client + +The implementation-level authority for this capability is +[HTTP Client Production Capability Deep Design](2026-07-27-httpclient-production-capability-design.md). +This subsection remains the cross-capability baseline; where detail differs, the dedicated design +governs. + +Preserve the current connect/read timeout intent, bounded-response intent, retry/circuit-breaker +seams, shutdown guard, and diagnostics as characterization inputs, not as proven guarantees. The +dedicated audit shows that the current `globalCallTimeout` only gates whether another retry may +start; it does not actively bound or cancel DNS, pool wait, connect, TLS, write, response body, or +backoff. It also shows that the documented decorator order differs from the code. If every physical +attempt must affect circuit-breaker state, retry repeats a circuit-breaker-wrapped attempt; the +logical-call deadline and concurrency bulkhead remain outside that loop. If a provider intentionally +measures one logical call instead, that is a different named policy and test suite, not an accidental +wrapper-order side effect. + +Add: + +- named client registry with per-dependency settings; +- explicit connection pool total/per-route limits, acquisition timeout, idle eviction, DNS policy, + and graceful close; +- bulkhead and optional outbound rate limit; +- retry only for declared safe/idempotent operations, with exponential jitter and + `Retry-After` handling; +- a single total deadline covering pool wait, attempts, backoff, and body read, with active + cancellation of the engine call and response stream when the budget expires; +- redirect disabled by default or host-allowlisted; +- scheme/host/port/CIDR allowlist and DNS rebinding/SSRF defense; +- TLS trust, hostname verification, mTLS, proxy, and certificate rotation; +- request/response header and body-size allowlists; +- upload/download streaming and cancellation; +- OTel instrumentation owns trace propagation. Remove the manual `traceparent` writer when the + real tracer is active; +- failure injection and pool-exhaustion tests. + +Use cases continue to depend on feature-specific anti-corruption ports such as `RepoStatsPort`, not +on `OutboundHttpClient`. + +### 13.2 Notification + +Split technical routing from business consent/preferences. + +Application intent contains: + +- channel; +- logical template ID and version; +- locale; +- recipient reference/address; +- typed template parameters; +- delivery mode and idempotency key; +- correlation/tenant context. + +Application/domain policy owns consent, preference, and quiet-hour decisions when those are +business rules. The adapter owns: + +- real provider clients; +- template rendering/versioning/localization; +- priority/fallback/fan-out routing; +- provider quotas and bounded retry; +- dedupe and provider idempotency key; +- durable mode through outbox/message; +- webhook signature verification and delivery receipts through an inbound adapter; +- bounce/suppression handling; +- PII-safe logs, encrypted queue content, and retention; +- per-provider health and delivery outcome metrics. + +Critical notification is never routed through the current unconditional fail-open path. Best-effort +and durable interfaces are explicit. + +### 13.3 Object storage + +The authoritative implementation-level design for this capability is +[Object Storage Production Capability Deep Design](2026-07-28-objectstorage-production-capability-design.md). +Its ordered RED–GREEN execution batches and promotion gates are in the +[Object Storage Production Capability Implementation Plan](../plans/2026-07-28-objectstorage-production-capability.md). +This subsection is only the cross-capability baseline; the dedicated design governs when details +differ. + +Replace whole-object `byte[]` as the only path with: + +- streaming upload/download and range reads; +- metadata/head contract; +- checksum algorithm/value contract and verification; +- conditional create/update/delete using version/ETag preconditions; +- presigned upload/download request with bounded expiry, content type, and size; +- multipart start/upload/complete/abort and orphan cleanup; +- server-side encryption and KMS settings; +- TLS/endpoint/region/credential-chain validation; +- lifecycle/versioning/retention policy checks; +- quarantine/malware-scan hook before publish; +- payload and metadata limits; +- metrics, tracing, and retry classification. + +Local filesystem and S3/MinIO pass the same semantic contract where the backend can support it. +Provider-specific optional capabilities are reported explicitly rather than silently emulated. + +Production defaults do not point to local MinIO, auto-create buckets, use static credentials, or +return internal filesystem paths to clients. + +Database state and object storage cannot share one local transaction. Workflows such as an image +attachment therefore use an explicit staged lifecycle: + +```text +stage upload -> verify checksum/scan -> commit attachment metadata -> finalize visibility +``` + +Failure paths use idempotent compensation plus an orphan reconciler with retention and audit +evidence. A use case must not perform an irreversible object write inside a database transaction +and assume rollback covers both systems. + +### 13.4 File server + +The authoritative implementation-level design for this capability is +[Fileserver Production Capability Deep Design](2026-07-26-fileserver-production-capability-design.md). +This subsection is only the cross-capability baseline; the dedicated design governs when details +differ. + +Replace the current whole-file `StringBuilder` and direct overwrite with: + +- streaming row writer/iterator; +- temporary file in the target directory; +- restrictive creation permissions; +- flush/fsync file, atomic rename when supported, and directory fsync where required; +- explicit fallback when the filesystem cannot guarantee atomic move; +- no-follow-link and real-path containment checks; +- overwrite/precondition policy; +- checksum and manifest; +- size/row/disk-space quota; +- retention/reaper and partial-file cleanup; +- filename/extension/content policy; +- spreadsheet-formula injection defense for CSV/tabular exports, with a tested escaping policy; +- optional encryption and malware scan; +- NFS/SFTP-specific locking, visibility, and rename semantics documented as provider capabilities. + +An exported file is identified by an opaque receipt. Absolute server paths are not public API +values. + +### 13.5 Identifier and support + +`adapter:outbound:identifier` continues to implement domain/application identifier ports. It may +offer random UUID and time-ordered ID providers, but ordering, clock rollback, collision, encoding, +and database-index tradeoffs are explicit. Pseudonymization keys support secret rotation and never +become reversible identifiers. + +`adapter:outbound:support` remains a small home for provider-neutral outbound decorators and +diagnostic helpers. It does not become a miscellaneous infrastructure module. Fail-open decorators +classify expected dependency failures and do not swallow programming/codec/invariant defects. + +## 14. Inbound transport baselines + +### 14.1 Web + +Preserve current validation, error envelope, authz, pagination/cursor, conditional request, OpenAPI, +request correlation, and safe cache-control foundations. Add: + +- exclusive JWT/session authentication profiles; +- Redis-backed transport-edge rate-limit contract and policy registry; +- actual keyed idempotency executor integration; +- trusted-proxy chain validation; +- request/header/body/multipart limits; +- request deadline and cancellation propagation; +- graceful drain; +- stable API version/deprecation policy; +- OpenAPI compatibility gate; +- CSRF/session cookie tests for stateful mode; +- route-level security/rate/idempotency capability declarations. + +### 14.2 GraphQL + +Production baseline: + +- shared authentication/tenant context; +- operation and field authorization; +- parser character/token/rule-depth limits; +- query depth and cost/complexity instrumentation; +- persisted-query allowlist profile; +- DataLoader/batch-loader convention and N+1 contract; +- cursor connection and bounded page policy; +- sanitized error extensions; +- introspection/GraphiQL production policy; +- schema snapshot/breaking-change check; +- query duration/complexity/error metrics; +- subscription transport delegated to an explicitly designed WebSocket/messaging path. + +### 14.3 gRPC + +Production baseline: + +- protobuf generation/versioning convention and compatibility check; +- TLS/mTLS and service/method authorization interceptors; +- required client deadlines and server cancellation propagation; +- request/response and metadata size limits; +- retry policy only for suitable status/method semantics; +- keepalive coordinated with infrastructure; +- unary and streaming backpressure/cancellation; +- standard health status updated during startup/drain/shutdown; +- reflection opt-in outside production; +- graceful shutdown and in-flight drain; +- OTel RPC semantic spans and bounded metrics. + +### 14.4 WebSocket + +The simple in-memory STOMP broker remains local/R1 only. + +Production baseline: + +- authenticated handshake and re-auth/session-expiry behavior; +- destination-level subscribe/send authorization; +- trusted origins and payload/frame limits; +- heartbeat and idle timeout; +- bounded inbound/outbound executors, queues, send time, and an explicit disconnect/drop policy; +- sequence/resume contract where message loss matters; +- per-session ordering only when required and measured; +- broker relay or a durable integration-event bridge for multi-node delivery; +- broker availability/readiness and graceful disconnect; +- no direct serialization of arbitrary domain events to public destinations. + +Cross-node durable live updates consume an integration/presentation event. The in-process Spring +event bus is not a durable or cluster-wide transport. + +## 15. Observability and operational safety + +### Signals + +- Traces: inbound server, application use case, DB/Redis, messaging producer/consumer, HTTP, object + storage, notification, and background-worker spans with standard semantic conventions. +- Metrics: request/dependency latency, errors, saturation, backlog/lag, lease loss, retry, DLT, + cache behavior, and provider lifecycle. +- Logs: stable structured schema correlated with trace/span IDs. +- Audit: a separate durable, access-controlled record for security/business actions; not ordinary + application logs. + +Instrumentation uses one context-propagation owner per transport. Payloads, tokens, Redis keys, +session IDs, raw principals, email addresses, and object names are not added to metrics and are +allowlisted or pseudonymized in logs/traces. + +Production tracing includes a configured OTLP exporter and batch span processor; tests use an +in-memory exporter to prove spans and propagation rather than treating a registry entry as emitted +telemetry. Metrics similarly prove recording, tags, and cardinality. Unmatched or templating-failed +HTTP requests use a fixed route label such as `UNKNOWN`, never a raw URI. + +### Health + +| Probe | Rule | +| --- | --- | +| Liveness | JVM/process ability only; never DB, Redis, Kafka, SMTP, object storage, or HTTP dependencies | +| Readiness | enabled providers marked required for this deployment | +| Component health | every enabled provider, including optional cache and notification | +| Startup | configuration, migration, script/schema compatibility, and required topology validation | + +Optional cache failure does not restart or necessarily unready the pod. Session, strict +idempotency, required lock, or required message publisher failure can make the application +unready. The capability descriptor decides; bean name presence does not. + +### Capacity and runbooks + +Each R2/R3 capability includes capacity inputs rather than fabricated numbers: + +- key/message/session/object size; +- operation rate and concurrency; +- retention/TTL; +- retry amplification; +- connection/thread/partition counts; +- replica/failover expectations; +- alert thresholds derived from an actual SLO. + +Required runbooks cover backlog, lag, DLT, stale lease, Redis memory/noeviction, session outage, +connector slot/WAL growth, index drift, multipart orphan, disk capacity, certificate expiry, and +provider credential rotation. + +## 16. Gradle and dependency design + +Rules: + +- `domain-core`, `application-core`, and `shared-contract` keep project-only production + dependencies and no Spring starter/SDK. +- A real provider dependency lives only in its owning adapter leaf. +- `implementation` is the default. `api` is used only when a public contract intentionally exposes + a third-party type, which these ports generally forbid. +- Spring Boot-managed coordinates use the Boot BOM. Non-Boot SDKs import a provider BOM at module + scope, following the existing gRPC/AWS pattern. +- Dependency locks and verification metadata change in the same implementation slice as the + dependency. +- Testcontainers, Toxiproxy, embedded brokers, and schema test tools remain test/integration-test + dependencies. +- Provider contract kits use Gradle test fixtures or a dedicated test-support source set without + becoming production dependencies. +- Integration tests receive a separate `integrationTest` task per provider; architecture checks + remain part of `check`. +- Do not introduce a version catalog solely for this work. The existing BOM/module pin model can be + retained until dependency ownership itself becomes hard to maintain. +- Tighten registry edges after implementation. Do not add speculative adapter-to-adapter edges. + +Expected dependency ownership: + +| Dependency family | Owner | +| --- | --- | +| Spring Data Redis/Lettuce and Spring Session Redis | Redis provider leaf | +| Kafka client/Spring Kafka producer | outbound messaging leaf | +| Kafka listener runtime | future inbound messaging leaf | +| Debezium/Kafka Connect | deployment/integration-test assets, not application-core | +| Mongo driver/Spring Data Mongo | Mongo persistence leaf | +| AWS S3 SDK | object-storage leaf | +| Resilience4j/HTTP engine | HTTP-client leaf | +| gRPC/protobuf runtime/build tooling | gRPC leaf | +| OTel/Micrometer exporter/composition | bootstrap and provider instrumentation adapters | + +The new Kafka inbound leaf is the only module addition proposed as structurally necessary in this +design. It requires an explicit `modules.json`, settings, Gradle dependency-gate, documentation, +and architecture-test migration rather than bypassing the exact-19 assertion. + +## 17. Verification and CI design + +### Test layers + +| Layer | Purpose | +| --- | --- | +| Pure unit | policy, algorithms, codec/version/key rules, retry/deadline math | +| Port contract | common required-semantics suite plus guarantee/capability-specific provider suites | +| Real-service integration | Redis, PostgreSQL, Mongo replica set, Kafka, MinIO, provider sandbox | +| Concurrency | duplicate claim, token spend, stale release, ordering, session sharing | +| Failure injection | timeout, disconnect, pool exhaustion, restart, failover, network partition | +| Compatibility | serialization, schema, migration, rolling version, Redis/Kafka/Mongo version | +| Architecture | SDK/type/dependency direction and optional-provider gating | +| Operational | health, metrics cardinality, trace propagation, secret/PII absence, graceful shutdown | + +Redis tests include standalone and cluster slot behavior, script reload, token mismatch, maxmemory +separation, and multiple client connections. CDC tests run PostgreSQL, Kafka, Kafka Connect/Debezium +end to end. Session tests use two application contexts against one Redis service. + +Providers in different guarantee classes are never certified as semantically identical. For +example, local/JDBC/Redis locks and filesystem/S3 storage share only the required contract subset; +fencing, conditional writes, multipart, durability, and failover claims require their own +capability suite. + +### CI profiles + +- PR gate: unit, architecture, provider contract, and one supported real-service baseline. +- Production-readiness gate: Docker/services are required; absence is a failure, not a silent skip. +- Nightly/weekly matrix: supported datastore/broker versions, cluster/failover, rolling + serialization, Toxiproxy, and longer concurrency/soak tests. +- Optional provider sandbox tests use explicit credentials and remain separated from deterministic + local protocol tests. +- Performance tests establish product-specific budgets later. This design requires load-test + hooks and capacity metrics, not generic benchmark claims. + +## 18. Phased implementation roadmap + +### Phase 0 — Correctness contracts and truthful capability topology + +- replace bean-name multi-instance checks with typed provider descriptors; +- remove or correct registry/settings claims for capabilities that do not exist; +- reconcile notification and JWT keys across the environment registry, YAML, typed settings, and + actual conditional beans; +- establish uniform explicit module/provider activation and prohibit missing-property activation + of local, plaintext, reflection, or auto-create defaults; +- publish a truthful default bootstrap capability manifest instead of equating source modules with + composed runtime features; +- correct and contract-test HTTP retry/circuit-breaker ordering and make the total deadline cancel + in-flight work; +- revise idempotency around owner token, lease, and replay TTL; +- distinguish efficiency lock, fenced lock, leadership, semaphore, and work claim; +- define capability cards, readiness levels, settings prefix, failure policy, and common contract + test kit; +- fix the local fixed-window key lifecycle or mark it dev-only with bounded storage; +- keep application-core dependency purity and all architecture gates green. + +Acceptance: the template cannot start in a configuration that claims an unavailable or weaker +provider guarantee. + +### Phase 1 — Real Redis foundation and cache + +- real Spring Data Redis/Lettuce client; +- cache/coordination/session role settings and connections; +- TLS/ACL/timeouts/pool/topology/health; +- versioned codec/key schema; +- cache get/put/evict/bulk/TTL/negative result; +- cache-aside, jitter, single-flight, after-commit invalidation; +- Redis standalone/cluster/failure/observability tests. + +Acceptance: cache reaches R2 while correctness Redis roles remain inactive unless selected. + +### Phase 2 — Distributed rate limit, idempotency, locks, and sessions + +- shared transport-edge rate-limit contract plus fixed/sliding-counter/token-bucket Lua providers; +- policy registry and emergency fallback; +- Redis/JPA idempotency contract implementations; +- JDBC/Redis lock provider selection, owner-safe renew/release, fenced lock; +- JWT/Redis-session exclusive profiles and multi-pod session contract. + +Acceptance: each selected provider has explicit guarantees and failure behavior; no correctness data +uses the evictable cache role. + +### Phase 3 — Kafka, polling outbox evolution, inbox, and CDC + +- acknowledgement-aware real Kafka producer; +- immutable `outbox_event` plus polling `outbox_delivery`; +- claim token and aggregate sequence; +- add inbound Kafka leaf and inbox executor/provider; +- retry/DLT/replay/backpressure/graceful lifecycle; +- Debezium connector/deployment assets and end-to-end CDC profile; +- polling/CDC exclusivity and transition runbook. + +Acceptance: both dispatch modes independently satisfy at-least-once delivery and idempotent-consumer +contracts without an exactly-once claim. + +### Phase 4 — HTTP, notification, object storage, and file server + +- complete HTTP pool/bulkhead/SSRF/TLS/OTel baseline; +- durable notification intent, provider routing, templates, receipts; +- streaming/multipart/presigned/checksum/encryption storage contracts plus staged finalization, + compensation, and orphan reconciliation; +- atomic streaming file exports, quotas, retention, CSV formula defense, and + filesystem-provider semantics. + +Acceptance: each adapter has a real R2 provider, failure injection, health, metrics, and a capability +card. + +### Phase 5 — JPA/Mongo query models and inbound transports + +- read consistency and replica routing; +- same-store and separate read-model profiles with checkpoint/lag; +- Mongo concerns/indexes/migrations/transactions/change streams; +- GraphQL complexity/DataLoader/schema gates; +- gRPC TLS/auth/deadline/streaming/proto gates; +- WebSocket broker relay/backpressure/auth/cluster behavior; +- route/operation capability declarations across transports. + +Acceptance: query and transport choices are explicit and operationally observable without leaking +transport or persistence types into core. + +### Phase 6 — R3 scale and extraction review + +- failover, rolling upgrade, version matrix, recovery drills, and capacity runbooks; +- evaluate splitting Redis capability-provider leaves; +- evaluate extracting a platform BOM/starter only after multiple real consumers validate the APIs. + +## 19. Completion criteria for the future implementation + +The implementation is complete only when: + +- every enabled capability has a real provider rather than a project-supplied seam; +- provider selection is exact, typed, and fail-fast; +- the provider guarantee and non-guarantees are visible; +- unused capabilities have no runtime side effects; +- core modules remain framework/SDK-free; +- every provider passes reusable contract plus real-service/failure tests; +- correctness and optimization data stores are separated where eviction/failure semantics differ; +- health, metrics, traces, logs, graceful lifecycle, security, and runbook are present; +- CI has a non-skipping production-readiness path; +- no cross-database exactly-once or strong Redis-lock claim appears in code or documentation. + +## 20.

+- soft/hard TTL; +- TTL jitter; +- invalidate/delete; +- conditional write; +- bulk get/evict; +- namespace generation; +- schema version; +- payload size; +- corruption outcome; +- after-commit invalidation; +- stampede suppression; +- stale-if-error. + +특히 `put(key, value)`에 TTL이 없으므로 단순 `SET` 구현은 immortal cache를 만든다. + +### 3.5 장애와 miss가 합쳐진다 + +`FailOpenCacheStore`는 모든 backend를 중앙에서 감싸고 모든 `Exception`을 다음처럼 처리한다. + +```text +get failure -> Optional.empty() +put failure -> swallow +``` + +따라서 정상 miss, timeout, connection failure, wrong-type, corrupt payload, codec bug, +programming defect를 caller가 구분할 수 없다. 성능 최적화용 cache의 일부 장애에는 fail-open이 +가능하지만, codec bug까지 miss로 숨기는 것은 장애 증폭과 source overload를 만든다. session, +idempotency, strict rate limit, lock에 이 decorator를 재사용하는 것은 금지한다. + +### 3.6 multi-instance mode는 현재 조립할 수 없다 + +`APP_MULTI_INSTANCE_ENABLED=true`는 bean name으로 다음 다섯 개를 요구한다. + +```text +distributedLockProvider +cacheStampedeProtection +outboxLeaderElection +distributedRateLimiter +migrationStartupRunner +``` + +현재 production composition에는 `cacheStampedeProtection`과 `distributedRateLimiter` 두 bean이 +없고 test configuration만 다섯 이름의 plain `Object`를 제공한다. 그러므로 현재 실제 composition은 +multi-instance mode에서 반드시 startup failure가 난다. 더 큰 문제는 단순 bean name 검사가 +provider topology나 guarantee를 검증하지 않는다는 점이다. + +### 3.7 rate limit은 fixed-window local map 하나다 + +현재 `RateLimitAlgorithm`은 `FIXED_WINDOW`만 제공한다. `FixedWindowRateLimiter`는 process-local +`ConcurrentHashMap`을 사용하므로 pod마다 quota가 따로 존재하고 key removal policy가 없다. + +추가 결함은 다음과 같다. + +- authenticated key에 route/policy dimension이 없다. +- raw principal/IP를 Redis key로 옮길 위험이 있다. +- window boundary concurrency contract가 없다. +- `Retry-After`가 decision이 아니라 고정 1초에 묶여 있다. +- invalid limit/window가 fail-fast하지 않고 default로 조용히 바뀐다. +- key cardinality budget과 cleanup이 없다. + +### 3.8 idempotency와 lock port는 Redis provider를 안전하게 수용하지 못한다 + +현재 `IdempotencyStorePort`는: + +```text +find(scope) +tryBegin(scope, fingerprint, expiresAt) +complete(scope, response) +discard(scope) +``` + +형태다. `complete`와 `discard`에 owner token이 없어 old owner의 lease가 만료된 후 new owner가 +claim해도 stale owner가 새 record를 덮어쓰거나 삭제할 수 있다. processing lease와 completed +response replay TTL도 하나의 TTL로 합쳐져 있다. + +현재 `DistributedLockPort`는 acquired handle의 `close()`만 제공한다. owner token, renewal, +lease-lost, current validity, fencing token, acquire/release의 unknown outcome을 표현하지 못한다. +문서상 efficiency lock인 점은 올바르지만 Redis provider를 붙일 계약으로는 불충분하다. + +### 3.9 configuration registry와 runtime이 어긋난다 + +registry에는 Redis host, port, password, cache TTL 관련 key가 있지만 typed settings와 실제 +client 소비자는 없다. `application.yml`에는 사실상 enabled flag만 있다. + +빠진 운영 설정은 다음과 같다. + +- standalone/Sentinel/Cluster; +- endpoint discovery와 DB index; +- TLS와 hostname verification; +- ACL username/password secret reference; +- connect/command/acquire/overall timeout; +- request queue와 pool bound; +- topology refresh와 redirect limit; +- primary/replica read policy; +- client name; +- shutdown/drain; +- role별 required/readiness; +- server/program/schema compatibility. + +### 3.10 현재 test가 증명하는 범위 + +현행 focused test는 통과한다. + +```text +./gradlew :adapter:outbound:cache-redis:test --rerun-tasks --console=plain +19 tests, failures/errors/skipped 0 +``` + +이 test는 fake seam의 routing과 fail-open 동작을 증명한다. 실제 Redis command, TTL, Lua, +eviction, replication, failover, Cluster slot, TLS/ACL, session, concurrency는 증명하지 않는다. + +## 4. 범위와 명시적 비범위 + +### 4.1 R2 baseline에 포함 + +- Spring Data Redis + Lettuce real provider;

HARD invariants + +구현은 다음 조건을 모두 지켜야 한다. + +1. `domain-core`에는 Redis, cache, session, rate-limit 기술 개념이 없다. +2. `application-core`에는 Spring, Lettuce, Redis command, key syntax, Lua, serializer SDK가 없다. +3. application use case는 `RedisTemplate`, connection, raw command executor를 받지 않는다. +4. transport rate limit과 business quota를 같은 port로 합치지 않는다. +5. session repository를 application port로 추상화하지 않는다. +6. cache miss와 backend unavailable을 같은 결과로 합치지 않는다. +7. codec/schema/programming 오류는 fail-open miss로 숨기지 않는다. +8. correctness capability는 evictable cache role에 bind하지 않는다. +9. Redis database number와 prefix를 workload isolation으로 간주하지 않는다. +10. expirable write는 value write와 TTL을 한 atomic command/program에서 수행한다. +11. lock release/renew는 owner token을 비교한다. blind `DEL`/`PEXPIRE`는 금지한다. +12. idempotency complete/release는 owner token과 claim revision을 비교한다. +13. multi-command read/decide/write를 “Redis가 single-thread이므로 안전”하다고 설명하지 않는다. +14. Lua/Function은 bounded complexity와 bounded state growth를 가져야 한다. +15. program은 classpath/provisioned artifact로 version/checksum이 고정된다. +16. runtime caller가 동적 script source나 key name을 programmatically 생성하지 않는다. +17. Cluster multi-key atomic operation은 같은 slot임을 key builder와 test가 보장한다. +18. timeout/reset 후 mutation 결과를 자동으로 `FAILED`라고 단정하지 않는다. +19. non-idempotent mutation을 결과 확인 없이 무조건 retry하지 않는다. +20. `WAIT`, `WAITAOF`, AOF, replica를 strong consistency나 zero-loss로 표현하지 않는다. +21.

Cluster redirect, Lua result, +timeout certainty, connection lifecycle을 새 interface가 부정확하게 복제한다. + +선택하지 않는다. + +### B. application에 범용 `RedisPort` 제공 + +예를 들어 `get/set/incr/zadd/eval`을 application port로 노출하면 개발자는 빠르게 기능을 만들 수 +있다. 대신 use case가 provider key, TTL, serialization, data structure, atomic recipe를 직접 +소유하고 Clean Architecture 경계가 무너진다. 안전 helper가 아닌 raw infrastructure facade가 된다. + +선택하지 않는다. + +### C. capability-provider마다 즉시 leaf 분리 + +```text +cache-redis +rate-limit-redis +lock-redis +idempotency-redis +session-redis +``` + +물리 격리는 가장 명확하다. 그러나 현재 exact-19 registry를 즉시 바꾸고 동일 client/config/program +기반을 여러 module에 중복한다. semantic contract가 아직 구현으로 검증되지 않은 시점에 public +path를 고정하는 비용이 크다. + +R2 첫 단계에는 선택하지 않는다. 독립 release/security/dependency lifecycle이 생기면 다시 +평가한다. + +### D. 한 physical Redis leaf, capability별 package와 semantic port + +현재 registry를 유지하면서 실제 SDK와 공통 key/codec/program runtime을 한 곳에 둘 수 있다. +동시에 capability별 provider, failure policy, settings, test kit를 분리할 수 있다. + +선택한다. 단, “한 leaf”는 “한 connection”, “한 Redis deployment”, “한 fail-open policy”를 +뜻하지 않는다. + +### E. Redisson API를 중심으로 모든 기능 제공 + +Redisson은 lock, rate limiter, map cache 같은 고수준 primitive를 제공한다. 구현량은 줄지만 +provider-specific semantics와 watchdog/failover 가정이 application policy에 스며들기 쉽고, +Spring Data/Spring Session과 별도 client lifecycle이 중복될 수 있다. + +기본 선택으로 사용하지 않는다. 특정 product가 Redisson capability를 선택할 경우 동일 semantic +contract와 contract suite를 통과하는 별도 provider로 추가할 수 있다. + +### F. Redis Functions만 허용 + +Functions는 server에 versioned library를 배포하고 runtime 계정에서 `FCALL`만 허용하기 쉬워 +production least privilege에 유리하다. 그러나 일부 managed Redis의 provisioning 권한, version, +배포 lifecycle이 다르고 모든 primary에 선배포해야 한다. + +production 권장 profile로 열어두지만 portable R2의 유일한 모드로 강제하지 않는다.

JDK client의 pool, DNS, TLS, redirect, proxy, cancellation과 lifecycle이 운영 계약에 없다. +6. 모든 dependency가 하나의 global settings를 공유하며 실제 destination registry가 없다. +7. sample의 feature-specific port와 fixture consumer는 있지만, production semantic port 구현과 + 실제 HTTP operation/binding이 없다. +8. manual trace header가 실제 tracer의 sampling 결정을 훼손하고 tenant baggage를 모든 목적지로 + 보낼 수 있다. +9. arbitrary URI, header, credential, redirect와 DNS rebinding에 대한 egress 보안 경계가 없다. +10. unknown mutation outcome, partial body, decode failure, pool timeout과 cancellation이 + `4xx/5xx/connect/timeout` 몇 개로 합쳐진다. + +이번 설계의 목표는 범용 `execute(method, url, body)` SDK가 아니다. + +> feature-specific application port 뒤에서, 등록된 destination과 operation만 호출하고, +> 하나의 monotonic deadline 안에서 admission·pool·DNS·connect·TLS·write·response·body·retry를 +> 제한하며, retry safety·unknown outcome·보안·관측성·취소를 실행 가능한 계약으로 증명하는 +> outbound HTTP capability + +선택한 핵심 구조는 다음과 같다. + +1. Application은 `OutboundHttpClient`가 아니라 `FraudScreeningPort`, + `PartnerCatalogPort` 같은 feature-specific anti-corruption port에 의존한다. +2. HTTP method, path template, success status, media type, retry safety와 body replayability는 + adapter의 typed operation catalog에 등록한다. +3. 호출자는 arbitrary absolute URL이나 raw credential header를 전달하지 않는다. +4. destination binding과 provider activation은 canonical configuration 하나로 결정한다. +5. 하나의 total deadline은 모든 대기와 physical attempt를 포함하며 timeout 때 engine call과 + response stream을 적극 취소한다. +6. retry는 method 이름만이 아니라 operation semantics, request identity, replayable body, + failure phase, remaining budget를 모두 만족할 때만 가능하다. +7. mutation이 전송된 뒤 응답을 잃으면 일반 transient failure가 아니라 + `INDETERMINATE`로 반환하고 provider-specific inspect/reconcile을 요구한다. +8. circuit breaker는 기본적으로 physical attempt를 집계하고, 논리 호출 집계는 별도 이름의 + 선택 정책으로만 허용한다. +9. Apache HttpComponents 5 classic + blocking facade를 초기 R2 reference candidate로 삼고, + hard-cancel evidence를 통과할 때만 baseline provider로 승격한다. JDK/HTTP2/reactive engine도 + 같은 보장을 통과할 때만 R2로 승격한다. +10. OTel instrumentation이 trace propagation을 단독 소유하며 manual MDC `traceparent` + writer는 제거한다. +11. no binding이면 client, pool, evictor, credential refresh, DNS probe가 하나도 생성되지 않는다. +12. capability별 readiness card가 실제 선택된 operation profile과 engine evidence를 검증한다. + +## 2. 상위 통합 설계와 이번 심화 범위 + +상위 설계의 HTTP client 절은 다음 방향을 이미 정했다. + +- named client registry와 dependency별 설정; +- pool total/per-route/acquisition/idle/DNS/lifecycle; +- bulkhead와 optional outbound rate limit; +- declared-safe operation만 retry; +- total deadline과 active cancellation; +- redirect와 SSRF 방어; +- TLS, mTLS, proxy, certificate rotation; +- request/response bounds; +- upload/download streaming; +- OTel trace ownership; +- failure injection과 pool exhaustion test; +- application의 feature-specific anti-corruption port. + +이번 문서는 위 방향을 구현 계획으로 변환할 수 있도록 다음을 확정한다. + +- application port와 adapter-internal kernel의 정확한 경계; +- destination, operation, attempt, logical call의 identity; +- request/response/body 타입과 lifecycle; +- absolute deadline과 phase budget; +- retry, circuit breaker, bulkhead, rate limiter의 정확한 실행 순서; +- safe/idempotent/replayable/unknown outcome의 차이; +- status별 default와 operation override; +- pool과 HTTP/1.1·HTTP/2 capacity model; +- DNS refresh, IP allowlist, rebinding, redirect와 proxy 검증; +- TLS trust, hostname verification, mTLS와 credential rotation; +- buffered, streaming upload/download, compression과 decode limit; +- error taxonomy와 application mapping; +- metrics, span, log, health와 cardinality; +- typed activation/configuration과 zero-side-effect 비활성 상태; +- provider engine 선택과 Gradle dependency ownership; +- real-network, TLS, DNS, proxy, failure-injection test; +- capability별 R2 readiness card와 CI aggregate; +- 기존 `OutboundHttpClient`에서의 단계적 migration. + +## 3. 증거 기반 현재 상태 + +### 3.1 실제 HTTP capability binding이 없다 + +현재 `adapter-outbound-httpclient`는 `shared-contract`와 +`adapter-outbound-support`에만 project dependency를 둔다. Registry는 application/domain edge를 +허용하지만 production code는 application의 어떤 semantic port도 구현하지 않는다. + +`OutboundHttpClient`는 adapter package의 기술 타입이며 기본 bean도 없다. README는 fork가 +dependency별 configuration에서 `baseline(...)`을 직접 호출하도록 안내한다. repository 전체에서 +이를 호출하는 production consumer는 없다. + +초기 조사 시점에는 component scan이 `OutboundHttpSettings`, shutdown guard, +`RestClient`/builder 차단 BeanPostProcessor, error mapper, logger와 retry policy를 생성해 +“binding 0개”와 “HTTP resource 0개”가 일치하지 않았다. Phase 1 구현에서 이 결함은 폐쇄됐다. +현재 settings와 두 legacy configuration은 global scan 대상이 아니며 canonical composition은 +immutable configuration, registry, resolver와 sanitized `DISABLED_VERIFIED` descriptor만 만든다. +기본 `application.yml`과 `application-test.yml`도 legacy `app.outbound.http.*`를 선언하지 않는다. + +다만 sample에는 이미 다음 seam이 있다. + +- `RepoStatsPort`; +- `GetRepoStatsUseCase`; +- `RepoStatsPortClient` stub; +- `/worklogs/repoStats` endpoint. + +이는 application port와 consumer skeleton이 없다는 뜻이 아니다. `RepoStatsPortClient`의 +`fetchRaw()`가 고정 fixture를 반환하므로 실제 HTTP capability를 소비하지 않는다는 뜻이다. +현재 sample registry edge에도 `sample-portfolio -> adapter-outbound-httpclient`가 없다. + +따라서 정확한 현재 상태는 다음과 같다. + +```text +HTTP leaf: + settings + generic technical wrapper + tests + +sample: + feature-specific port + use case + fixture adapter + +but: + no real HTTP operation/binding between them + != +feature-specific application port + upstream adapter + runtime binding +``` + +현재 capability level은 R0 seam과 일부 R1 local kernel 사이이며 R2가 아니다. + +### 3.2 total deadline이 실행을 제한하지 않는다 + +`OutboundHttpClient.exchange()`는 다음 deadline을 계산한다. + +```java +Instant deadline = Instant.now().plus(settings.globalCallTimeout()); +retryPolicy.beginCall(method, deadline); +``` + +그러나 이 값은 `OutboundRetryPolicy.shouldRetry()`가 다음 retry를 시작할지 확인할 때만 사용한다. +현재 attempt를 중단하지 않고 다음도 포함하지 않는다. + +- connection/pool wait; +- DNS; +- connect와 TLS handshake; +- request body write; +- response header wait; +- response body read; +- streaming reader callback; +- retry backoff 자체; +- circuit-breaker/bulkhead wait. + +첫 attempt가 `globalCallTimeout`보다 오래 걸려도 read timeout 전까지 계속 실행된다. Retry +predicate가 deadline 직전 true를 반환하면 남은 시간보다 긴 새 attempt도 시작할 수 있다. +`stream()`은 이 deadline을 검사만 하는 수준도 아니며 absolute deadline/retry context/cancel +handle을 아예 만들거나 전달하지 않는다. 그러므로 application.yml의 “whole call including +retries” 주석과 runtime behavior가 일치하지 않는다. + +### 3.3 retry와 circuit breaker 합성 설명이 코드와 반대다 + +현재 코드는 다음 순서로 decorator를 만든다. + +```java +Supplier<T> decorated = countingSupplier; +decorated = Retry.decorateSupplier(retry, decorated); +decorated = CircuitBreaker.decorateSupplier(cb, decorated); +``` + +실행 구조는 다음과 같다. + +```text +CircuitBreaker( + Retry( + physical attempt + ) +) +``` + +따라서 circuit breaker는 retry가 끝난 논리 호출 하나를 집계한다. README와 코드 주석은 +“retry가 circuit breaker 바깥이고 각 attempt가 독립 집계된다”고 설명한다. 원하는 physical +attempt 집계는 다음 구조여야 한다. + +```text +Retry loop( + CircuitBreaker( + one physical attempt + ) +) +``` + +현재 test는 retry hit count와 meter 존재를 확인하지만 circuit-breaker sliding window가 physical +attempt를 몇 건 집계했는지는 검증하지 않는다. + +### 3.4 streaming은 status error를 성공 body처럼 전달한다 + +buffered 경로는 `retrieve()`를 사용해 default 4xx/5xx handler가 예외를 발생시킨다. Streaming +경로는 `exchange(...)` callback을 사용하면서 status를 확인하지 않는다. + +Spring Framework는 `RestClient.exchange()`에서 status handler가 자동 적용되지 않는다고 +명시한다. Callback이 status를 직접 처리해야 한다. + +현재 구현: + +```java +streamingClient + .method(method) + .uri(uri) + .exchange((req, res) -> reader.apply(res.getBody())); +``` + +그 결과 401, 429, 500도 body reader가 정상 결과로 만들 수 있고 +`observer.recordSuccess(...)`가 호출된다. + +### 3.5 streaming이 size limit의 무제한 우회 경로다 + +현재 buffered response는 `Content-Length`와 counting stream으로 10 MB 기본 한계를 확인한다. +그러나 streaming 경로에는 다음 제한이 없다. + +- maximum wire bytes; +- maximum decoded bytes; +- logical total deadline across retries/backoff; +- 별도의 no-progress body idle deadline; +- content type와 content encoding; +- record/item count; +- reader output size; +- compression expansion ratio. + +현재 `JdkClientHttpRequestFactory#setReadTimeout`은 selected Spring Framework 7 구현에서 +`sendAsync` completion에 timer를 걸고 timeout 때 future/response body를 cancel/close하는 +attempt elapsed timeout에 가깝다. 이를 socket byte-idle timeout이나 logical-call total +deadline이라고 부르지 않는다. Non-cooperative callback의 CPU loop도 제한하지 못한다. + +README와 test는 buffered limit을 넘으면 streaming API를 사용하면 된다고 설명하고, test는 +oversized response 전체를 성공적으로 읽는 것을 기대한다. Streaming은 heap materialization을 +피하는 방법이지 무제한 데이터 허용 권한이 아니다. + +### 3.6 request 계약이 너무 넓고 동시에 부족하다 + +현재 API: + +```java +<T> T exchange(HttpMethod method, String uri, Object requestBody, Class<T> responseType) +<T> T stream(HttpMethod method, String uri, Function<InputStream, T> reader) +``` + +문제: + +- raw Spring `HttpMethod`와 transport `InputStream`이 public adapter API에 노출된다. +- `String uri`가 relative path인지 absolute URI인지 강제하지 않는다. +- path/query encoding과 template variable allowlist가 없다. +- caller가 operation ID나 low-cardinality route template을 제공하지 않는다. +- request header, `Accept`, `Content-Type`, API version, conditional header를 표현하지 못한다. +- authentication profile이나 credential ownership이 없다. +- status별 success/domain outcome mapping이 없다. +- `Class<T>`는 generic collection과 versioned envelope를 충분히 표현하지 못한다. +- request body byte limit과 replayability가 없다. +- operation-specific deadline과 resilience policy가 없다. + +이 API를 application에 그대로 노출하면 Clean Architecture의 anti-corruption boundary가 사라진다. + +### 3.7 retry safety가 method set 하나에 묶여 있다 + +현재 retry allowlist는 `GET`, `HEAD`, `PUT`, `DELETE`다. `POST`, `PATCH`는 항상 거부한다. + +HTTP method의 idempotency는 중요한 출발점이지만 충분하지 않다. + +- upstream이 PUT/DELETE를 문서와 다르게 구현할 수 있다. +- request body stream이 다시 열리지 않을 수 있다. +- idempotent effect여도 각 response는 다를 수 있다. +- conditional request가 precondition 없이 재실행될 수 있다. +- POST/PATCH도 upstream이 durable idempotency-key와 replay contract를 제공하면 안전할 수 있다. +- connect reset이 request 전송 전인지 후인지 모르면 mutation outcome은 불명확하다. + +RFC 9110도 non-idempotent request 자동 retry는 operation semantics를 실제로 알거나 최초 요청이 +적용되지 않았음을 아는 경우가 아니면 하지 말라고 요구한다. + +### 3.8 모든 4xx와 많은 transport error가 뭉친다 + +현재 error mapper는: + +- 400~499 전체를 `DEPENDENCY_4XX_CLIENT`; +- 500 이상 전체를 `DEPENDENCY_5XX_SERVER`; +- 알 수 없는 failure를 `DEPENDENCY_CONNECT_FAILED`; +- shutdown reject를 `DEPENDENCY_CIRCUIT_OPEN`; +- connect timeout을 `DEPENDENCY_CONNECT_FAILED`; +- 나머지 timeout을 `DEPENDENCY_TIMEOUT`; + +으로 분류한다. + +이 분류로는 다음을 결정할 수 없다. + +- 401 credential refresh 후 정확히 한 번 replay 가능한가; +- 404가 정상적인 absence인가 API drift인가; +- 408/425/429의 retry 조건은 무엇인가; +- 409/412가 domain conflict/precondition outcome인가; +- 413이 request contract 위반인가; +- 415/406이 media negotiation drift인가; +- 422가 permanent validation인가 idempotency fingerprint mismatch인가; +- 502/503/504와 일반 500의 retry 차이는 무엇인가; +- TLS trust, hostname, certificate expiry, proxy auth failure는 무엇인가; +- pool acquire와 local admission reject를 구분할 수 있는가; +- response가 일부 도착한 뒤 잘렸는가; +- mutation이 적용됐는지 모르는가. + +### 3.9 JDK client의 운영 자원 정책이 없다 + +현재 factory는 destination마다 다음 client를 만든다. + +```java +HttpClient.newBuilder() + .connectTimeout(settings.connectTimeout()) + .build(); +``` + +명시하지 않은 항목: + +- executor; +- HTTP version; +- redirect; +- proxy; +- authenticator/cookie handler; +- SSL context/parameters; +- connection capacity와 per-route isolation; +- acquisition timeout; +- connection TTL/idle validation; +- DNS resolver/TTL/address selection; +- shutdown/close ownership; +- pool metrics. + +Java 21 JDK client에는 builder-level total/per-route pool과 connection lease timeout을 구성하는 +API가 없다. `jdk.httpclient.connectionPoolSize`는 HTTP/1.1 keep-alive cache의 구현 property이며 +application-level admission이나 per-destination active-call bound를 대체하지 않는다. + +### 3.10 global settings가 destination 정책을 표현하지 못한다 + +`app.outbound.http.*` 하나가 모든 dependency에 적용된다. + +실제 운영에서는 다음이 destination마다 다르다. + +- base URI와 allowed address; +- API version; +- required/optional readiness impact; +- timeout/SLO; +- pool capacity; +- protocol version; +- TLS trust and mTLS identity; +- authentication; +- proxy; +- request/response size; +- retryable statuses와 idempotency contract; +- circuit-breaker threshold; +- rate quota; +- trace/baggage/privacy policy. + +현재 required global timeout placeholder는 실제 client binding이 0개여도 bootstrap 설정을 +요구한다. 반대로 client가 여러 개여도 서로 다른 정책을 지정할 수 없다. + +### 3.11 manual trace propagation은 fork landmine이 아니라 현재 결함이다 + +`TraceContextPropagationInterceptor`는 MDC의 `trace_id`와 `span_id`로 `traceparent`를 만들고 +sampled flag를 항상 `00`으로 기록한다. 실제 tracer가 있어도 먼저 설정된 header를 보존하도록 +구성되면 downstream sampling decision을 끊을 수 있다. + +추가로 `request_id`와 `tenant_id`를 `baggage`로 모든 destination에 전파한다. Tenant ID가 내부 +service boundary에서는 필요할 수 있어도 외부 partner에 보내도 된다는 뜻은 아니다. Destination별 +data-sharing policy 없는 global allowlist는 privacy boundary가 아니다. + +W3C `traceparent`/`tracestate` mutation과 sampling flag는 tracer propagator가 소유해야 한다. +MDC reconstruction은 fallback으로도 기본 활성화하지 않는다. + +### 3.12 observability가 logical call과 attempt를 구분하지 않는다 + +현재 logger는 dependency, outcome, total duration, retry count를 남기지만: + +- operation ID가 없다. +- HTTP status class가 없다. +- pool/DNS/connect/TLS/write/header/body phase가 없다. +- physical attempt별 span과 duration이 없다. +- cancellation과 indeterminate outcome이 없다. +- request/response bytes가 없다. +- actual HTTP client duration meter가 없다. +- pool leased/available/pending meter가 없다. + +Resilience4j metric filter는 shared `MeterRegistry`에 전역으로 설치되고 +`resilience4j.*` 중 세 meter 외 전부 deny한다. 동일 registry를 사용하는 다른 capability의 +Resilience4j meter까지 차단할 수 있다. 현재 singleton configuration에서는 한 번 설치되지만, +다중 ApplicationContext 또는 fork가 config를 수동 구성하면 같은 global filter가 반복 설치될 수 +있다. + +### 3.13 lifecycle guard가 drain/cancel/close를 수행하지 않는다 + +`OutboundHttpShutdownGuard.stop()`은 boolean을 변경할 뿐: + +- in-flight call count; +- graceful drain deadline; +- pending retry/backoff cancellation; +- response stream close; +- HTTP engine close; +- idle evictor stop; +- credential refresh scheduler stop; +- forced cancellation; + +을 수행하지 않는다. + +새 호출을 reject하는 것은 필요하지만 resource lifecycle 전체는 아니다. Shutdown을 +`DEPENDENCY_CIRCUIT_OPEN`으로 재사용하는 것도 잘못된 operational diagnosis다. + +### 3.14 현재 test가 증명하는 범위 + +2026-07-27 baseline: + +```text +./gradlew :adapter:outbound:httpclient:check --rerun-tasks --console=plain +BUILD SUCCESSFUL +``` + +현재 unit/local test는 다음을 증명한다. + +- settings의 일부 numeric validation; +- local JDK HttpServer에 대한 200/4xx/5xx/read-timeout mapping; +- GET retry hit count와 POST no-retry; +- circuit-open short-circuit; +- response `Content-Length`/chunked counting; +- manual MDC header propagation; +- basic logs와 Resilience4j meters; +- shutdown boolean gating. + +증명하지 않는 항목: + +- real total deadline와 hard cancellation; +- CB physical-attempt count; +- streaming 4xx/5xx rejection; +- connection pool saturation/acquisition/idle/TTL; +- TLS/mTLS/hostname/certificate rotation; +- DNS TTL/rebinding/address failover; +- redirect/proxy/SSRF; +- compressed body expansion; +- streaming cancellation/partial output; +- mutation unknown outcome와 idempotency replay; +- OAuth token refresh; +- HTTP/2 multiplexing/GOAWAY; +- process shutdown drain; +- multi-destination isolation; +- real observability instrumentation. + +현재 compile에는 `ThreadLocalUsage`, locale 없는 `toUpperCase`, test default charset 등 기존 +ErrorProne warning이 있지만 focused check는 성공한다. + +### 3.15 Retry wiring이 object identity에 의존한다 + +`OutboundHttpClient.baseline(...)`은 `OutboundHttpResilience`와 `OutboundRetryPolicy`를 별도 +parameter로 받는다. Client는 전달받은 policy에 ThreadLocal call context를 기록하지만, +Resilience4j retry predicate는 `OutboundHttpResilience`를 만들 때 캡처한 policy를 호출한다. + +두 policy instance가 다르면 predicate는 context가 없다고 판단해 retry를 조용히 비활성화한다. +현재 test도 이를 critical wiring constraint로 설명한다. Type system, constructor, composition +validation은 동일 instance를 강제하지 않는다. + +R2 state machine은 ThreadLocal/object-identity coupling을 제거한다. + +- immutable attempt context를 retry decision에 명시적으로 전달; +- retry loop와 decision policy를 한 aggregate가 소유; +- 동일 instance를 수동으로 맞춰야 하는 factory signature 제거; +- composition mismatch characterization test; +- virtual-thread/async boundary에서도 context loss 없음. + +### 3.16 Response-size violation이 retry와 diagnosis를 깨뜨린다 + +`ResponseSizeBoundingInterceptor`가 size exception을 발생시키지만 현재 error mapper는 이를 +stable contract failure로 알지 못한다. Unknown runtime failure fallback이 +`DEPENDENCY_CONNECT_FAILED`이며 retryable이므로 retry-enabled safe method는 같은 oversized +response를 반복 다운로드할 수 있다. + +추가 영향: + +- 최종 size exception이 observer failure path 밖에서 발생해 structured failure log가 빠질 수 있음; +- 큰 4xx/5xx body가 status mapping 전에 size exception으로 바뀌어 원래 status를 잃을 수 있음; +- 현재 size tests는 retry disabled 상태만 검증. + +R2는 status/header를 먼저 분기하고 wire/decoded bound failure를 +`RESPONSE_TOO_LARGE`/`DECOMPRESSION_LIMIT_EXCEEDED`로 매핑한다. 둘은 default no-retry, +circuit-breaker ignore이며 logical failure observation을 정확히 한 번 남긴다. + +## 4. 범위와 명시적 비범위 + +### 4.1 전체 production capability 설계 범위 + +- synchronous/virtual-thread-friendly request-response capability; +- JSON과 bounded binary buffered response; +- bounded streaming download callback; +- bounded/reopenable streaming upload callback; +- named destination와 typed operation catalog; +- relative path template와 typed query/header mapping; +- per-destination Apache HttpComponents classic engine; +- explicit HTTP/1.1 connection pool; +- monotonic total deadline와 active cancellation; +- retry, retry budget, physical-attempt circuit breaker; +- logical admission과 attempt bulkhead; +- optional local outbound quota limiter; +- safe/idempotent/idempotency-key/non-retryable operation; +- unknown mutation outcome와 reconciliation hook; +- redirect disabled default와 future-card용 exact allowlisted state-machine; +- DNS/address/SSRF validation; +- HTTPS/TLS hostname verification, custom trust와 mTLS; +- static bearer/API key/OAuth2 client credentials seams; HTTP Basic은 future-card-only; +- proxy allowlist와 proxy-auth profile; +- content type/encoding/header/body bounds; +- OTel/Micrometer observation ownership; +- typed configuration, activation, lifecycle, health; +- real TCP/TLS/DNS/proxy/failure integration tests; +- readiness card와 runbook. + +위 목록은 이 문서가 설계하는 전체 surface이지 한 번에 R2로 승인되는 minimum profile이 아니다. +R2는 derived selected card와 exact full effective profile tuple 범위에서만 주장한다. + +### 4.2 Minimum R2 static baseline + +최소 ACTIVE R2 profile은 `httpclient-static-buffered` 하나와 그 exact compatibility profile만 +선택하고 다음으로 제한한다. + +- fixed registered destination + relative route; +- synchronous H1; +- bodiless 또는 bounded JSON buffered request/response; +- `SAFE_READ`; +- server TLS/hostname verification; +- auth `none`; +- direct-only, redirect/cookie/engine-hidden-retry disabled; +- finite admission/pool/body/deadline와 hard cancellation; +- safe-read retry budget와 physical-attempt circuit breaker; +- OTel sanitizer, lifecycle, readiness와 runbook. + +다음은 minimum profile 밖이다. + +- `IDEMPOTENT_MUTATION`/`KEYED_MUTATION` -> `httpclient-idempotent-mutation`; +- `NON_RETRYABLE_MUTATION` -> `httpclient-non-retryable-mutation`; +- streaming download/upload -> 각각의 streaming card; +- mTLS, OAuth2 client credentials, required proxy, HTTP/2, untrusted fetch -> 각각의 card. + +Bounded binary, custom server trust, API key와 static bearer는 새 card ID를 만들지 않고 +`httpclient-static-buffered`의 conditional effective mode로 지원할 수 있다. 단 profile +compatibility registry에 provider/protocol/request·response body/TLS/auth/proxy/redirect/ +operation-semantics 전체 tuple이 exact entry로 존재하고 mode-specific 및 cross-mode +HSEC/HRES/HOBS/HCMP scenario가 모두 포함된 경우에만 활성화한다. 기본 card 시나리오나 축별 +지원 합집합만으로 이를 지원했다고 간주하지 않는다. + +Redirect-follow, request-signature와 HTTP Basic은 현재 canonical card set에서 지원하지 않는다. +관련 state-machine 설계는 future card를 위한 것이며, mode가 설정되면 card 등록 전에는 +startup/readiness가 실패한다. “disabled by default”는 켤 수 있다는 의미가 아니다. + +### 4.3 별도 optional capability로 열어둘 항목 + +- HTTP Service Interface proxy; +- conditional GET/ETag; +- RFC-compliant HTTP cache; +- HTTP/2 multiplexed engine; +- reactive `WebClient` engine; +- OAuth2 token exchange/JWT bearer; +- HTTP message signatures; +- resumable/range download; +- multipart/form-data upload; +- webhook callback registration; +- controlled dynamic public egress through an egress proxy; +- service discovery/load-balancer integration; +- client-side hedging for safe reads; +- response streaming to file/objectstorage workflow; +- provider-specific rate-limit header interpretation. + +Optional 항목은 같은 raw API에 boolean을 추가하지 않는다. 요구 guarantee, dependency, +concurrency model이 다르면 별도 readiness card와 provider profile을 갖는다. + +### 4.4 이번 범위에서 제외 + +- controller/inbound DTO와 HTTP server behavior; +- WebSocket, SSE long-lived subscription, gRPC; +- business saga/compensation; +- business-level batch orchestration; +- external API별 domain DTO와 mapping; +- arbitrary user URL fetcher; +- browser cookie/session emulation; +- transparent application-wide retry annotation/AOP; +- distributed transaction; +- service mesh/egress gateway 자체의 설치; +- synthetic benchmark 수치; +- HTTP/3 production baseline. + +사용자가 제공한 URL을 fetch해야 하는 feature는 일반 destination client가 아니다.

Token endpoint, in-call reconciliation, HTTP CONNECT proxy와 named HTTP OCSP/CRL lookup의 +각 실제 HTTP request도 자신의 bounded counter와 같은 root-call total token을 소비한다. +Redirect/auth refresh/retry가 중첩돼도 곱셈 증폭되지 않는다. DNS query와 A/AAAA별 TCP connect는 +HTTP request가 아니므로 이 token 대신 resolver/per-address connect cap과 같은 total deadline을 +사용한다. Deferred reconciliation use case가 나중에 독립 호출로 시작되면 새 root-call budget을 +갖지만 같은 operation identity와 별도 scheduler quota를 유지한다. + +`maxAttempts`라는 모호한 이름은 canonical model에서 사용하지 않는다. Operation별 ordinary retry +횟수와 위 physical/root ceiling을 분리한다. Runtime config가 catalog 상한을 낮출 수는 있지만 +증가시킬 수 없다. Protected/root 상한은 finite positive이고 비활성일 수 있는 child 상한은 finite +non-negative이며 다음 cross-field invariant를 만족한다. + +```text +1 <= maxProtectedPhysicalAttemptsPerLogicalCall +maxNestedCredentialRequestsPerLogicalCall >= 0 +maxReconciliationRequestsPerLogicalCall >= 0 +maxProxyConnectRequestsPerRootCall >= 0 +maxRevocationHttpRequestsPerRootCall >= 0 +maxTotalHttpRequestAttemptsPerRootCall >= minimumRequiredRootHttpAttempts(effective profile) +``` + +`minimumRequiredRootHttpAttempts`는 exact profile의 cold-path scenario마다 계산한다. 최소 initial +protected request, OAuth cache miss/401 refresh, required proxy CONNECT, hard-fail revocation lookup와 +advertised auth replay에 필요한 protected request를 포함한다. 예를 들어 one-401 OAuth replay를 +지원하면 protected ceiling은 최소 2이고 해당 scenario의 token refresh + 두 protected requests가 +root ceiling 안에 들어야 한다. Root ceiling이 reason-specific maxima의 합보다 작을 수는 있지만, +그 때문에 required scenario 하나라도 구조적으로 실행 불가능하면 startup/qualification이 실패한다. + +Protected origin 밖에서 실제 HTTP request를 만드는 child path는 공통 authorization protocol을 +사용한다. + +```text +NestedHttpRequestKind = OAUTH_TOKEN | RECONCILIATION | PROXY_CONNECT | REVOCATION +NestedHttpAuthorizationLease( + kind, + rootCallId, + childProfileFingerprint, + childAttemptOrdinal, + state = AUTHORIZED | BOUND_TO_ENGINE | ABORTED +) +``` + +`NestedHttpAuthorizationBroker`는 parent root context가 이 lease만 발급하는 최소 capability이며 +provider/child adapter에 mutable counter나 refill API를 노출하지 않는다. Broker 생성 시 exact +dependency DAG에서 다음 immutable edge set을 캡처한다. + +```text +AllowedChildEdge( + parentProfileFingerprint, + kind, + childProfileFingerprint, + childOperationId, + childAuthorityPolicyFingerprint +) +``` + +Caller가 전달한 kind/profile/operation edge가 이 set과 exact match하지 않거나 다른 root의 broker/ +lease를 재사용하면 child/root token 소비 전에 거절한다. Lease bind 시 provider가 제출한 resolved +child profile, operation, scheme/authority-policy fingerprint도 lease edge와 byte-for-byte 일치해야 +한다. 따라서 broker를 generic registered-child/authority oracle로 사용할 수 없다. +`tryAuthorizeNestedHttpRequest`는 deadline/cancellation과 해당 child cap의 순수 availability를 먼저 +검사하고, exact child counter token을 원자적으로 한 번 소비해 lease를 만든다. 실제 wire start +직전에는 같은 root-call total HTTP token 하나를 uncommitted reserve하고 cancellation과 engine +handoff를 race한다. Handoff가 이기면 lease/root token을 bind/commit하고, 그 전 실패면 root token은 +반납하되 child reason token은 amplification churn을 막기 위해 되살리지 않고 lease를 `ABORTED`로 +exactly once 닫는다. Cache hit, 기존 CONNECT tunnel 재사용처럼 HTTP request가 발생하지 않는 +경로는 lease/token을 소비하지 않는다. Provider가 이 broker를 호출하지 않고 child HTTP request를 +시작할 수 있으면 해당 profile은 release-eligible이 아니다. + +`TransportConnectAttempt`는 A/AAAA address candidate 하나에 대한 connect 시도이며 +`HttpRequestAttempt`와 다르다. Request byte 전 address failover는 connect event/metric일 뿐 +`http.request.resend_count`나 physical attempt ordinal을 증가시키지 않는다. First request byte 뒤 +재연결은 새 `HttpRequestAttempt`이며 operation state machine 승인이 필요하다. + +Engine autonomous resend가 start 전 shared token/deadline/body/CB/bulkhead/span gate를 호출할 수 +없으면 hidden resend를 비활성화해야 하며 해당 provider/profile은 release-eligible이 아니다. +사후 관측만으로 공통 상한을 지켰다고 주장하지 않는다. + +### 9.5 Operation attempt ID와 idempotency key + +Mutation은 application workflow가 생성해 재시도/재시작에도 보존하는 안정적인 +`OperationAttemptId`를 가질 수 있다. Adapter는 이를 upstream 형식의 idempotency key로 encode한다. + +규칙: + +- 첫 network call 전에 생성; +- response loss 뒤에도 caller가 보유; +- payload fingerprint와 결합; +- 다른 intent에 재사용 금지; +- log/metric에 raw value 금지; +- provider가 expiry와 replay semantics를 문서화한 경우에만 retry 근거. + +### 9.6 Policy revision + +Destination와 operation policy에는 stable ID와 revision/digest가 있다. + +```text +destination profile: partner-catalog-r2 / revision 4 +operation profile: partner-catalog.get-product.v1 / revision 2 +``` + +같은 revision의 canonical digest가 배포 사이에서 달라지면 startup을 실패시킨다. Rolling +deployment에서 retry semantics가 조용히 변하는 것을 막는다. + +## 10. Application semantic port와 adapter boundary + +### 10.1 Feature-specific port 원칙 + +Application port는 upstream HTTP API를 복제하지 않고 use case가 필요한 의미만 노출한다. + +좋은 예: + +```java +public interface FraudScreeningPort { + ScreeningDecision evaluate(ScreeningSubject subject, CallBudget budget); +} +``` + +나쁜 예: + +```java +public interface HttpPort { + HttpResponse execute(String method, String url, Map<String, String> headers, Object body); +} +``` + +### 10.2 Wire DTO 격리 + +Adapter 흐름: + +```text +application request + -> upstream request mapper + -> wire DTO + -> registered HTTP operation + -> wire response DTO + -> schema/semantic validation + -> application result +``` + +Wire DTO는: + +- upstream field name/version/null semantics를 소유; +- Jackson annotation을 가질 수 있음; +- application/domain package로 반환하지 않음; +- tolerant read와 required semantic validation을 분리; +- raw problem detail/error body를 application에 노출하지 않음. + +### 10.3 Application failure shape + +Application port마다 의미 있는 결과를 선택한다. + +예: + +```text +Found +NotFound +RejectedByPartner +TemporarilyUnavailable +Indeterminate(operationAttemptId) +``` + +모든 port가 같은 generic exception을 강제로 사용하지 않는다. Kernel failure를 adapter가 +operation 의미에 맞게 매핑한다. + +### 10.4 Call budget + +Use case 전체에 이미 deadline이 있으면 application은 framework-neutral absolute budget을 +전달할 수 있다. + +```java +public record CallBudget(long monotonicDeadlineNanos) { +} +``` + +실제 contract는 다음을 만족해야 한다. + +- `System.nanoTime()`과 같은 monotonic time domain; +- wall-clock timestamp로 serialize하지 않음; +- destination policy cap과 `min`으로 결합; +- 이미 만료되면 network side effect 없이 reject; +- child call이 parent보다 긴 budget을 만들 수 없음. + +`Duration timeout`만 매번 전달하면 nested call이 호출 시점마다 새 budget을 받아 상위 deadline을 +넘길 수 있으므로 absolute budget을 선호한다. + +### 10.5 Adapter-consumer SPI와 internal kernel + +Kernel은 application/controller에 공개하지 않는다. 다만 sample-local outbound adapter나 future +domain-specific outbound leaf가 capability를 재사용할 수 있도록 최소 adapter-consumer SPI를 +공개한다. + +개념 예: + +```java +interface RegisteredHttpOperationInvoker { + <Req, Res> HttpCallResult<Res> execute( + HttpOperation<Req, Res> operation, + Req request, + CallContext context); +} +``` + +`HttpOperation`은 registry와 fingerprint가 일치하는 immutable descriptor다. Caller는 method, +absolute URL, raw header, credential, retry boolean을 runtime에 제공하지 않는다. + +Boundary: + +- application/domain/inbound package의 SPI import는 ArchUnit으로 금지; +- adapter/sample outbound package만 사용; +- operation 등록은 startup 전 완료하고 runtime dynamic registration 금지; +- descriptor/codec/wire DTO는 consumer adapter 소유 가능; +- kernel provider/Apache/Spring type은 SPI에 노출하지 않음; +- public-path snapshot으로 accidental generic SDK surface 확장을 검출. + +HTTP leaf 안에서 provider와 resilience를 다루는 `HttpTransportEngine`은 계속 internal이다. + +### 10.6 HTTP Service Interface 사용 + +Spring HTTP Service Interface는 다음 조건에서 adapter-internal wire client로 사용할 수 있다. + +- interface와 annotation이 adapter package에 위치; +- feature-specific application port를 별도로 구현; +- group/destination이 canonical registry와 1:1로 검증; +- underlying `RestClient`가 동일 kernel의 engine, auth, bounds, observation을 사용; +- proxy가 kernel의 retry/deadline을 우회하지 않음; +- method metadata가 operation catalog와 build-time 대조됨; +- return type이 wire DTO이며 domain/application DTO가 아님. + +단순 `@ImportHttpServices` classpath scan으로 새 client를 자동 활성화하지 않는다. + +## 11.

Operation catalog는 runtime +request가 정책을 선택하는 것을 막고 code review 가능한 안전 계약을 제공한다. + +### 11.2 Operation descriptor + +개념적 `HttpOperation<Req, Res>` 필드: + +| 필드 | 의미 | +| --- | --- | +| `operationId` | stable low-cardinality ID | +| `destinationId` | exact destination binding | +| `policyRevision` | rolling compatibility revision | +| `method` | fixed HTTP method | +| `routeTemplate` | low-cardinality relative template | +| `semantics` | `SAFE_READ`, `IDEMPOTENT_MUTATION`, `KEYED_MUTATION`, `NON_RETRYABLE_MUTATION` | +| `requestMode` | `NONE`, `BUFFERED`, `REOPENABLE_STREAM`, `SINGLE_USE_STREAM` | +| `responseMode` | `BODILESS`, `BUFFERED`, `STREAM_CALLBACK` | +| `requestCodecId` | wire encoder | +| `responseCodecId` | wire decoder | +| `successContractId` | accepted status/media/schema | +| `errorContractId` | operation-specific status mapping | +| `deadlineProfileId` | phase/total budget profile | +| `retryProfileId` | retry decision/backoff/budget | +| `resilienceGroupId` | CB/bulkhead state-sharing group | +| `authProfileId` | adapter-owned credential profile | +| `egressPolicyId` | URI/address/redirect/proxy policy | +| `observabilityProfileId` | route template and privacy policy | +| `readinessCardIds` | evidence required before R2 | + +Runtime caller가 이 필드를 override하지 않는다. + +### 11.3 Executable definition과 review registry + +다음 이중 구조를 사용한다. + +1.

Child-level safe-read retry를 허용하면 새 wire request마다 새 poll + ordinal/lease가 필요하고 child retry budget availability도 같은 atomic authorization에 포함한다. +5. Child request의 body/pool/quota/bulkhead/CB acquisition 뒤 wire start 직전에 shared root HTTP token을 + reserve한다. Cancellation/start race에서 start가 이길 때만 lease/root token을 bind/commit한다. + Pre-bind exit는 lease를 `ABORTED`로 exactly once 닫고 uncommitted root/quota를 반납한다. 현재 + logical call에서 detached background task를 만들지 않는다. +6. `CONFIRMED_NOT_APPLIED`만 same operation identity의 `REPLAY_SAME_INTENT`로 돌아가며 별도 replay + budget과 protected/root physical token을 소비한다. 나머지는 위 mapping대로 terminal/receipt다. + +Deadline 안에 확인되지 않으면 kernel은 `Indeterminate` receipt를 반환한다. 이후 scheduler/use +case가 수행하는 reconciliation은 새 root-call budget과 별도 scheduler quota를 갖고 원래 +operation-attempt identity를 이어받는다. + +### 16.8 Application orchestration + +HTTP kernel이 business compensation을 수행하지 않는다. + +```text +use case + -> stable operation attempt ID 저장/보유 + -> outbound port mutation + -> Indeterminate + -> reconciliation use case/scheduler + -> confirmed state + -> next business transition/compensation +``` + +DB transaction 안에서 remote HTTP mutation을 호출하고 rollback이 remote effect도 취소한다고 +가정하지 않는다. + +## 17.

Lease가 다음 +loop로 carrying되므로 auth/retry/replay 분기가 다시 token을 소비하지 않는다. Initial request에는 +`INITIAL` authorization marker만 있고 reason token은 없다. Authorized 뒤 deadline, refresh 또는 +final protected/root reservation이 실패하면 lease는 `ABORTED`로 exactly once 닫고 default로 token을 +환불하지 않아 churn이 amplification budget을 되살리지 못하게 한다. Circuit permission, local +quota와 protected/root physical token은 이 lease와 별도로 §20의 실제 attempt 경계에서 획득한다. + +Disposition/semantics gate: + +| Semantics | Ordinary subsequent attempt | +| --- | --- | +| `SAFE_READ` | `RESTART_CONFIRMED_NOT_SENT` 또는 `RETRY_SAFE_READ` | +| `IDEMPOTENT_MUTATION` | `RESTART_CONFIRMED_NOT_SENT`; same-intent/H2-not-processed는 별도 state | +| `KEYED_MUTATION` | `RESTART_CONFIRMED_NOT_SENT`; reconciliation/same-intent/H2-not-processed는 별도 state | +| `NON_RETRYABLE_MUTATION` | default 금지; explicit protected ceiling 2 + reopenable body + restart budget의 `RESTART_CONFIRMED_NOT_SENT`, 또는 H2 exact opt-in의 `RESTART_CONFIRMED_NOT_PROCESSED`만 | + +`REPLAY_SAME_INTENT`, `RESTART_CONFIRMED_NOT_PROCESSED`, `REFRESH_CREDENTIAL_AND_REPLAY`와 +`FOLLOW_DECLARED_REDIRECT`는 ordinary retry predicate를 재사용하지 않고 동일 pure-eligibility + +reason-specific `AttemptAuthorizationLease` protocol을 사용한다. `RECONCILE_SAME_OPERATION`은 prior +protected attempt를 반복하지 않고 §16.7의 registered child state로 들어가며, 각 실제 reconciliation +HTTP request는 별도 `NestedHttpAuthorizationLease`에 bind된다. 모든 state는 동일 +key/fingerprint/scope와 shared root ceiling을 유지한다. + +### 17.2 Backoff + +Default: + +- exponential backoff; +- full jitter 또는 decorrelated jitter를 명시; +- zero busy-loop 금지; +- upper cap; +- absolute deadline cap; +- retry budget cap. + +예시 full jitter: + +```text +cap_n = min(maxBackoff, initialBackoff * 2^n) +sleep_n = random(0, cap_n) +sleep_n = min(sleep_n, remaining - minimumAttemptBudget) +``` + +Random source는 test에서 deterministic injection 가능해야 한다. + +### 17.3 `Retry-After` + +408/429/503 등 operation이 허용한 status에서만 해석한다. + +- delta-seconds와 HTTP-date만 허용하고 multiple/mixed 값은 invalid; +- malformed, negative 또는 overflow delta는 server hint를 버리고 bounded client jitter로 fallback; +- 문법상 valid하지만 과거인 HTTP-date는 `serverMinimumDelay=0`으로 두되 client jitter는 유지; +- maximum cap; +- wall-clock skew tolerance; +- remaining deadline보다 길면 현재 logical call에서는 retry하지 않음; +- provider-specific rate-reset header는 별도 parser; +- invalid header는 bounded metric, raw value log 금지. + +Server hint와 client jitter 조합은: + +```text +delay = max(serverMinimumDelay, clientBackoffWithJitter) +``` + +를 기본으로 하되 operation contract가 다르면 명시한다. + +### 17.4 Retry budget + +대규모 장애 때 모든 최초 호출이 N번 retry하면 outage를 증폭한다.

Raw path/query/header와 +unsanitized absolute URL을 OTel SDK, processor, sampler 또는 exporter에 한 번도 전달하지 않는다. +In-memory SDK/exporter test는 forbidden fixture 값이 생성된 attribute/event/link 전체에 0회 존재함을 +검증한다. + +Semantic convention 준수와 privacy가 충돌하는 selected instrumentation/version이면 조용히 raw +URL을 내보내지 않는다. Sanitized absolute URL contract를 구현하거나 해당 provider/card를 +release-eligible로 승격하지 않고 deviation을 descriptor에 명시한다. + +### 31.6 Resilience4j metric ownership + +현재 adapter가 설치하는 global `MeterFilter.DENY`는 제거 대상이다. 한 capability가 application +전체의 `resilience4j.*` meter를 차단하면 Redis, messaging 등 다른 capability의 관측 계약을 +깨뜨릴 수 있다. + +두 선택지 중 하나를 composition root에서 명시한다. + +1. registry가 허용한 Resilience4j meter를 bounded name/tag로 등록한다. +2. native binder를 사용하지 않고 HTTP adapter가 semantic logical/physical metric만 직접 + 기록한다. + +초기 구현은 2를 권장한다.

+``` + +Kafka `send()`는 일반적으로 local buffer에 record를 넣고 future를 즉시 반환한다. 외부 seam이 +future를 기다리는지, 어떤 `acks`를 쓰는지, delivery timeout이 유한한지 repository는 알 수 없다. +그런데 application의 `OutboxEventStatus.PUBLISHED` 문서는 broker acknowledgement를 뜻한다고 +설명한다. + +현재 seam 구현자가 callback/future 완료 전에 정상 반환하면 relay는 ACK가 없는 record를 +`PUBLISHED`로 기록한다. 이는 단순한 구현 누락이 아니라 현재 상태 이름과 실제 evidence의 +불일치다. + +### 3.3 event type이 physical topic으로 사용된다 + +현재 `OutboxMessagePublishAdapter`는 다음 매핑을 한다. + +```text +topic = event.eventType() +key = event.aggregateId() +payload = hand-written envelope +``` + +이 구조는 application event naming이 Kafka topic naming, ACL, retention, partition count, +replication, environment naming과 결합되게 한다. event type을 동적으로 만들 수 있으면 arbitrary +topic publication과 metric cardinality도 열린다. + +목표에서는 `contractId -> logicalDestination -> physicalTopicBinding`의 닫힌 두 단계 mapping을 +사용한다. + +### 3.4 envelope가 schema-bound document가 아니다 + +`OutboxEnvelopeJson`은 문자열을 직접 이어 붙인다. payload는 “이미 올바른 JSON”이라는 주석 +계약만 있고 parser/schema validation 없이 verbatim 삽입된다. + +현재 envelope에는 다음도 없다. + +- envelope spec version; +- payload schema version; +- contract ID; +- aggregate type와 aggregate sequence; +- causation ID; +- content type; +- logical destination; +- schema hash/compatibility evidence; +- maximum depth/string/array/record bytes;

`expected-mode`는 application +policy와 일치하는지 검증하는 assertion일 뿐이며 mismatch는 startup failure다. config가 +best-effort를 durable로 “강화”하는 것도 transaction sequencing과 business failure 의미를 +바꾸므로 금지한다. mode 변경은 application policy revision과 해당 feature use case의 transaction +sequence를 함께 변경하고 검증해야 한다. + +### 11.4 transaction sequence와 use case capability + +현재 `TransactionPort.inWrite`는 `PROPAGATION_REQUIRED`이므로 이미 열린 outer transaction에 +참여할 수 있다. 따라서 단순히 `inWrite`가 반환했다는 사실을 physical commit 완료로 간주하면 +안 된다. synchronous `InlineCompleted`를 유지하는 최소 R2는 기존 application +`TransactionPort`에 `inRootWrite` 계약을 추가한다. + +이 port의 persistence implementation은 시작 전에 ambient physical transaction이 없음을 +검사하고, 있으면 business write나 provider call 전에 typed +`NestedRootTransactionRejectedException`으로 fail-fast한다. ambient transaction이 없을 때만 root REQUIRED +transaction을 열고 physical commit이 끝난 뒤 반환한다. + +```java +CommittedBusinessResult committed = + tx.inRootWrite( + () -> { + BusinessResult saved =

inlineAttemptUseCase.handle(committed.inlineDraft()); +``` + +durable kind는 기존 `TransactionPort.inWrite` 안에서 business write와 +`NotificationIntentAppendPort.append`를 함께 실행해 caller의 ambient transaction에도 +의도적으로 참여한다. append adapter는 `REQUIRES_NEW`를 사용하지 않는다. + +root transaction rollback/commit failure 또는 ambient transaction rejection이면 best-effort +provider call은 0이어야 한다. `outer inWrite -> best-effort feature use case -> outer rollback` +통합 테스트는 provider call 0과 root-boundary rejection을 증명한다. after-commit registration +방식을 향후 도입하면 synchronous `InlineCompleted`를 그대로 재사용하지 않고 별도 +`ScheduledAfterCommit` 계약/card로 설계한다. + +`inRootWrite`의 `TransactionMode`는 여전히 `WRITE`, propagation은 `REQUIRED`, +isolation은 `READ_COMMITTED`다. `NEVER` mode/propagation을 추가하지 않고 adapter가 transaction +시작 전 actual ambient transaction precondition을 검사한다. 구현 시 application-core와 +persistence-jpa의 `CLAUDE.md`/README, fake port와 transaction fitness/integration test를 함께 +갱신해야 한다. + +dispatcher는 `CommandUseCase`를 구현하고 다음 fitness contract를 선언한다. + +```java +@UseCaseCapability( + transactionMode = TransactionMode.WRITE, + idempotency = Idempotency.IDEMPOTENT, + repositoryAccess = RepositoryAccess.WRITE_REPOSITORY, + externalOutboundAllowed = true) +``` + +claim과 finalize는 각각 짧은 `TransactionPort.inWrite` 안에서 실행하고 provider call은 그 +사이에 transaction 밖에서 실행한다. application에는 `*Port`를 구현하는 policy class를 만들지 +않고, inbound use case/application policy/outbound port를 타입과 이름으로 구분한다. + +### 11.5 admission class + +application `NotificationKindPolicy`는 closed `NotificationAdmissionClass`도 선택한다. + +```text +SECURITY_CRITICAL +TRANSACTIONAL +BULK_LOW_VALUE +``` + +이 값은 intent에 저장되고 claim ordering/admission partition의 입력이 된다. config는 각 class의 +concurrency를 낮출 수만 있으며 kind의 class를 바꾸지 못한다. ordering은 +`admission class + bounded aging + next_action_at + notification_id`로 deterministic하게 +정의하고 낮은 class도 maximum starvation window 안에 기회를 얻어야 한다. + +## 12. durable state model + +### 12.1 state를 한 column에 합치지 않는다 + +최소 R2에서 intent 하나는 logical recipient 한 명을 갖고 여러 provider leg와 늦은 feedback을 +가질 수 있으므로 다음을 분리한다. + +```text +NotificationIntent + exactly 1 logical recipient + 1 -> N NotificationDeliveryLeg + 1 -> M immutable NotificationAttempt + 0 -> K immutable NotificationReceiptEvent +``` + +`NotificationDelivery`라는 기존 개념명은 provider leg를 뜻한다. 구현에서는 혼동을 피하기 위해 +`NotificationDeliveryLeg`를 우선 사용한다. intent summary는 leg state와 receipt fact에서 +파생하는 view/projection이다. provider별 부분 성공, fallback 대기 또는 bounce를 하나의 +`SENT` boolean으로 덮지 않는다. + +### 12.2 intent state + +권장 intent control state: + +```text +APPENDED +ACTIVE +COMPLETED +PARTIALLY_COMPLETED +TERMINAL_FAILED +CANCELLED +EXPIRED +``` + +`COMPLETED`는 이름만으로 최종 recipient 성공을 뜻하지 않으며, kind policy가 요구한 submission +objective를 만족했다는 뜻이다. +예를 들어 Slack은 `POSTED_TO_CONVERSATION`, transactional email은 +`PROVIDER_ACCEPTED` 또는 receipt policy에 따른 `DELIVERED_TO_RECIPIENT_MTA`가 될 수 있다. +서로 다른 기준을 같은 dashboard에서 비교할 때 capability card를 함께 표시한다. +후속 bounce/complaint는 immutable adverse fact/projection으로 함께 노출하며 accepted submission +fact를 지우지 않는다. + +### 12.3 delivery control state + +권장 provider leg

가능한 unknown은 +`RECONCILE_WAIT/RECONCILING`, horizon이 끝난 unknown은 `TERMINAL_INDETERMINATE`다. + +receipt는 단일 mutually-exclusive state가 아니라 immutable fact와 직교 projection으로 둔다. + +```text

SDK/client 호출은 이 +commit의 성공을 확인한 뒤에만 시작한다. 이 transaction은 expiry, cancellation request, +application policy recheck 결과, technical suppression, 모든 route/provider/account admission +gate의 expected generation이 `ACTIVE`인지와 attempt budget을 다시 검사한다. cancellation, +gate park와 wire authorization 중 먼저 commit된 transition이 이긴다. + +외부 consent/preferences store와 이 DB를 원자화할 수 없으므로 recheck 직후 revoke와 실제 send +사이의 race는 제거할 수 없다. 이 한계를 receipt나 exactly-once 표현으로 감추지 않는다. + +### 12.5 crash classification + +| crash/실패 위치 | 복구 판정 | +| --- | --- | +| claim 뒤 attempt reserve 전 | wire authorization이 없으므로 lease 만료 후 안전하게 re-claim | +| `ATTEMPT_RESERVED` 뒤 | wire authorization이 없으므로 안전하게 requeue | +| `WIRE_AUTHORIZED` commit 뒤 provider call 전 process kill | maybe-send window로 취급 | +| `WIRE_AUTHORIZED` 뒤 response 전 | reconcile 가능하면 `RECONCILE_WAIT`, 아니면 terminal unknown | +| provider accepted response 뒤 local projection update 전 | immutable attempt result를 terminal-once 기록한 뒤 projection 재적용 | +| local accepted commit 뒤 | accepted 유지, duplicate callback idempotent 적용 | +| receipt 저장 뒤 delivery projection update 전 | 같은 transaction이면 함께 rollback; 아니면 inbox 재적용 | + +delivery claim owner token과 immutable attempt execution token을 분리한다. lease를 잃은 worker도 +정확히 받은 provider response를 `(delivery_id, attempt_ordinal)`의 open attempt에 terminal-once로 +append할 수 있다. delivery projection은 현재 owner/version CAS로 merge하고, 이미 더 강한 +accepted/receipt fact를 stale result로 낮추지 않는다. + +`WIRE_AUTHORIZED` attempt는 `attempt_deadline + transport drain/finalize grace`가 지나기 전에는 +reaper가 retry나 fallback을 활성화하지 않는다. 그 뒤에도 provider card가 definite-not-applied를 +증명하지 않으면 reconcile/terminal unknown으로만 이동한다. DB linearization point와 실제 socket +write를 원자화할 수 없으므로 exactly-once를 주장하지 않는다. + +`TERMINAL_INDETERMINATE`는 자동 send/reconcile budget의 종료이지 과거 fact를 지우는 봉인이 +아니다. 나중에 도착한 verified receipt 또는 정확한 late provider response는 accepted projection으로 +단조롭게 해소할 수 있지만, 이를 이유로 새 physical send를 자동 시작하지 않는다. + +### 12.6 fallback atomicity + +predecessor leg의 attempt 결과가

constraint 또는 동등한 invariant로 강제한다. accepted, +bounce, complaint와 terminal indeterminate는 자동 fallback 사유가 아니다. cross-channel +escalation은 별도 application intent다. + +`PARK_BINDING`은 initial kernel에서 fallback을 활성화하지 않는다. parked primary는 active +fallback leg로 남아 secondary를 막는다. future exact fallback card가 park 시 chain advance를 +원하면 predecessor를 definite-not-applied terminal로 닫고 다음 leg 하나를 같은 transaction에서 +활성화하는 별도 reviewed policy/state를 추가해야 한다. + +## 13. planning, routing, fan-out과 fallback + +### 13.1 application intent와 adapter plan 분리 + +application은 logical `NotificationRouteId`를 선택한다. adapter의 immutable catalog/compiler가 +notification-local route/template/provider capability만 검증해 frozen plan을 만든다. + +```text +NotificationDeliveryPlan + routeId + revision + channel + strategy

application value로 돌아오되 target은 bounded opaque reference다. +provider SDK request나 secret/endpoint를 plan에 넣지 않는다. + +cross-module readiness를 이 compiler 하나에 넣지 않는다. + +| 검증 소유자 | 제공하는 framework-free

+provider list만 써놓고 strategy를 추론하지 않는다. 빈 list, duplicate target, channel mismatch, +capability mismatch, cycle 또는 상한 초과는 startup에서 실패한다. + +### 13.3 cross-channel fan-out + +email과 Slack을 모두 보내는 것은 대체로 business escalation/communication policy다. + +```text +feature application: + SECURITY_ALERT_EMAIL intent + SECURITY_ALERT_SLACK intent +``` + +하나의 outbound adapter route가 임의로 channel을 바꾸거나 email failure 뒤 Slack으로 넘어가지 +않는다. cross-channel fallback/escalation은 consent, urgency, duplicate tolerance가 다르므로 +application orchestration이 소유한다. + +### 13.4 fallback 안전 조건 + +다음 outcome만 기본 fallback

+config는 code maximum을 낮출 수만 있다. provider leg 수 × retry × fallback × reconcile의 +최악값이 `maxTotalProviderCallsPerIntent`를 넘으면 startup compiler가 거부한다. + +## 14. template, rendering과 localization + +###

mapping을 수행하되 network side effect를 만들지 않는다. +`sendOneAuthorizedAttempt` 한 번은 coordinator 관점의 한 authorized attempt다. 이름이나 구현으로 +wire-level exactly-once를 암시하지 않는다. + +correlation identity를 생성 시점과 의미에 따라 분리한다. + +```text +AttemptCorrelationId // send 전 생성, opaque/non-PII +ProviderClientOperationKey // provider가 native key를 지원할 때만 +ProviderMessageReference // accepted response/event 뒤에만 획득

`PROVIDER_ACCEPTED + NOT_APPLICABLE + DELIVERY` | + +HTTP status 하나만으로 transmission certainty를 일반화하지 않는다. 각 provider card에 exact +response/error mapping table과 protocol test를 둔다. + +`PARK_BINDING`은 `FaultScope`에 대응하는 shared admission gate를 닫고 readiness를 내리며 +backlog를 terminal 유실시키지 않는다. + +```text +NotificationAdmissionGate = + (scopeType, scopeRevision) + + state = ACTIVE | PARKED + + generation + + boundedReasonCode/faultScope + + parkedAt/resumedAt +``` + +attempt finalize transaction은 exact outcome fact를 append하고, gate를 expected generation의 +`ACTIVE -> PARKED`로 CAS하며, 현재 leg를 `PARKED_BINDING`으로 바꾼다. concurrent park는 +idempotent하게 같은/higher generation을 관측한다. 다른 node의 eligible scan과 +`WIRE_AUTHORIZED` transaction은 route/provider/account gate가 모두 ACTIVE일 때만 진행하므로 +restart/multi-instance에서도 park가 유지되고 hot-loop하지 않는다. + +gate park보다 먼저 `WIRE_AUTHORIZED`를 commit한 attempt는 이미 권한을 얻었으므로 bounded +completion/indeterminate protocol을 따른다. park는 새 wire authorization을 막지만 이미 시작한 +provider side effect를 recall한다고 주장하지 않는다. + +route revision 수정 또는 credential/account 복구 후 audited resume use case만 readiness/config를 +재검증하고 generation을 증가시켜 ACTIVE로 바꾼다. 같은 transaction/bounded batch에서 parked +leg의 expiry, cancellation, policy/suppression과 attempt budget을 다시 판단해 `QUEUED`, +`EXPIRED` 또는 `POLICY_REJECTED`로 이동한다. initial R2는 park를 fallback activation으로 +해석하지 않는다. + +### 15.5 retry ownership + +coordinator가 다음을 소유한다. + +- attempt authorization; +- attempt ordinal과 total count; +- absolute attempt deadline; +- retry horizon/expiry; +- full-jitter backoff;

Java verifier port는 +branch별 canonical payload/signature, bounded issuer SPKI bytes/digest, retained trust-snapshot +payload/digest와 current closed catalog의 historical `ALLOW|REVOKED` 판정을 다시 검증하고, +DB identity, birth/fence facts, discriminator, operation/registry/permit/inventory/attestation 및 +route/fence semantic exact equality를 재계산한다. BEGIN-less/orphan attestation, closing +operation 뒤의 attestation, child set 누락·초과, unselected/superseded row의 signature/trust/ +semantic mismatch도 fail closed한다. 이 전체 검증이 성공한 경우에만 readiness를 연다. +query/read 또는 Java 재검증 오류, forged direct-apply row와 retained-row corruption은 +모두 dark/`NOT_QUALIFIED`, provider I/O 0인 availability/integrity incident이며 SQL structural +success나 provisioning job success를 readiness로 승격하지 않는다. + +app-bootstrap은 composition과 use case 호출만 담당하고 repository, persistence entity, JDBC, +query adapter 또는 verifier 구현을 직접 사용하지 않는다. FINAL cleanup은 transitional write +controller/command/function/grant만 삭제한다. retained provenance/operation/registry/permit/ +inventory/attestation/fence row, 위 read use case/query port/read-only adapter/verifier port와 +구현은 startup/readiness evidence를 위해 계속 보존한다. issuer는 application 운영 주체와 +분리된 external infrastructure authority이며 production artifact, container, database와 +environment에는 private key를 두지 않는다. deterministic local issuer는 test fixture에서만 +허용하고 evidence grade를 `LOCAL_TEST`로 낮추며 production provisioning/readiness는 이를 +거부한다. authorization이 동봉한 임의 key나 unreviewed environment key는 trust anchor가 +아니다. + +PRE bridge 배포에서 legacy fence를 자동 seed하지 않는다. bridge admission을 열기 전에 인증된 +human operator가 batch `INITIALIZE_LEGACY`를 호출한다. canonical binding과 post-migration fresh +provisioning의 route key +SSOT인 canonical route catalog에 PRE-only legacy alias/transport proof를 더한 compiled cutover +route catalog와 별도 reviewed runtime target-generation config를 결합한 +bounded ordered `(route revision, reviewed predecessor generation)` set과 그 set의 digest, +opaque operation token, actor digest와 bounded reason code를 받는다. fence/operation/permit을 +포함한 control table과 intent/delivery/attempt/receipt/suppression/gate/alias를 포함한 data-plane +journal이 모두 빈 경우에만 모든 route의 `ACTIVE/LEGACY@initial` fence, operation header와 route +result rows, route별 current+retiring transport-proof registry snapshot을 같은 root transaction에서 +insert한다. persisted registry의 각 route는 active admission profile이 정확히 하나이고 모든 +row는 같은 route registry digest와 initialization child FK를 가진다. 이 table은 UPDATE/DELETE가 +금지된 retained audit history이며 permit acquire는 proof class/evidence revision을 여기서 row에 +동결한다. direct SQL, application startup hook, +V7 schema migration은 이 초기화를 수행하지 않는다. 일부 route만 초기화하는 sequential +operation도 금지한다. 서로 다른 token의 동시 batch 초기화는 정확히 한 건만 이기며, 같은 token과 +같은 route set/input의 replay는 저장된 전체 결과를 반환하고 token 재사용이나 route-set mismatch는 +fail closed한다. commit failure는 mutation/성공 응답 0이고, commit-success/result-loss retry는 +operation journal의 저장 결과로 복구한다. init 전 absent/partial/extra fence key set에서는 모든 +provider I/O가 0이다. batch init 뒤 route-by-route rollout에서는 exact catalog key set 안에서 +`ACTIVE/LEGACY@predecessor`, `DRAINING/LEGACY@predecessor`, +`ACTIVE/CANONICAL@target`의 closed state만 혼재할 수 있다. legacy node는 첫 상태 route만, +canonical PRE node는 마지막 상태 route만 열고 DRAINING/owner mismatch route는 모두 닫는다. +unrelated owner/state/generation이나 catalog key mismatch는 전체 composition/readiness를 fail +closed한다. + +route revision set과 그 digest는 request authority가 아니다. proxied initializer가 retained +canonical catalog와 PRE-only cutover decorator, reviewed target config에서 server-side로 +derive하고, request는 그 exact key set에 대한 reviewed predecessor +generation map, reason과 opaque token만 제공한다. missing/extra route key 또는 caller가 주장한 +별도 digest는 거부한다. initialization 뒤 PRE artifact는 compiled decorator와 persisted +registry의 route/profile/admission-role/proof-class/evidence-revision/digest exact equality를 +startup과 readiness에서 계속 검증한다. cutover 중 registry 변경은 in-place update로 허용하지 +않는다. 새 profile/evidence revision이 필요하면 기존 sandbox/rollout을 폐기하고 별도 설계된 +registry-version 절차 없이는 진행하지 않는다. + +canonical admission은 business write + intent append와 같은 caller transaction에서 fence row를 +`SELECT ...

design; implementation not started +- Date: 2026-07-28 +- Repository baseline: Java 21, Spring Boot 4.0.0, Gradle 9.0.0, 19 registered leaf modules +- Scope: test taxonomy, Clean Architecture boundary ownership, Gradle source sets/tasks, + service provisioning, data isolation, CI/release environments, non-functional qualification, + evidence and rollout +- Out of scope: implementing the suites, choosing an organization's SLO numbers, provisioning + production cloud accounts, or changing the 19-leaf production dependency graph + +## 1. Executive decision + +This repository does not need a larger undifferentiated test pyramid. It needs a **fail-closed +evidence ladder** in which each result says which boundary and environment it actually exercised. + +The proposed destination is: + +```text +source/static evidence + -> deterministic leaf tests + -> real-provider integration tests + -> migration compatibility tests + -> immutable-artifact system/smoke tests + -> scheduled operational qualification + -> post-deploy synthetic evidence +``` + +The core decisions are: + +1. Classify a test on three independent axes: + - **execution boundary**: unit, component/slice, integration, system; + - **verification purpose**: behavior, contract, architecture, migration, security, resilience, + performance, smoke; + - **environment**: in-memory, loopback, disposable container, provider sandbox, deployed + environment. +2. Keep `src/test` deterministic and independent of external infrastructure. It may use an + in-process Spring context or an ephemeral loopback port, but no Docker daemon, Internet service, + manually prestarted database, or fixed host port. +3. Put real PostgreSQL, Redis, MongoDB, Kafka, MinIO, SMTP, and fault-proxy tests in an owning + leaf's `src/integrationTest`. Selecting that lane is a promise to execute it: missing Docker, + zero discovered tests, or an unexpected skip is a failure, not a green build. +4. Add `migrationTest` only where its historical fixtures, destructive lifecycle, and release + frequency differ materially from ordinary integration tests. +5. Reserve `systemTest`/`E2E` for black-box tests of the built boot JAR or OCI image. A + `@WebMvcTest`, mocked repository, or custom test-only boot application is not E2E. +6. Keep tests in their owning registered leaf. Do not add a twentieth production `test-support` + module. Reusable port contract kits use Gradle test fixtures and test-only dependencies. +7. Use explicit Gradle `SourceSet` + `Test` tasks for the first implementation. Gradle's JVM Test + Suite model fits the problem, but remains incubating; this long-lived template favors the stable + mechanism already used by `sampleOffTest`. +8. Use Testcontainers for leaf/provider integration, a CI-specific disposable Compose override for + candidate-image system tests, and protected provider sandboxes only for compatibility claims + that local substitutes cannot establish. +9. Keep `check` Docker-free. CI explicitly fans in deterministic quality, mandatory provider + integration, sample-off, and candidate-image smoke jobs. +10. Treat PR-head artifacts as unpromotable. Reverify the protected main merge commit, build its + boot JAR once, copy that exact JAR into the canonical OCI image, and promote only that image + digest. +11. Do not adopt an arbitrary repository-wide coverage percentage as the definition of quality. + Record coverage first, require explicit risk scenarios, then ratchet changed-code coverage and + use mutation testing selectively for pure domain/application policy. + +## 2. Why this is the right problem + +The repository already has extensive tests, architecture guards, snapshots, Testcontainers, and a +flaky-test quarantine. The problem is not a lack of test classes. The problem is that materially +different evidence is mixed under the same `test` task, while some provider evidence is outside CI +or can disappear through conditional skip. + +A test called `ContractTest` can be a pure port contract, a real PostgreSQL contract, or an HTTP +schema contract. A test called `E2ETest` can still be a MockMvc slice. Names alone therefore cannot +route release evidence. + +The design must answer four questions for every important claim: + +- What production boundary was crossed? +- What was real and what was replaced? +- In which environment did it run? +- What can still be false even when the test passes? + +## 3. Evidence and audit scope + +### 3.1 Repository evidence + +The audit read: + +- `AGENTS.md`, root and leaf `CLAUDE.md` files; +- `src/config/architecture/modules.json`, `src/settings.gradle`, root and leaf Gradle files; +- all `src/test/java` and `src/test/groovy` trees; +- Dockerfiles and Compose files; +- `.github/ci-gate-matrix.yml` and GitHub Actions workflows; +- existing production-capability and CI design documents. + +The inspected worktree was `main` with pre-existing local changes. Those changes were preserved. +Counts below describe that worktree, not a clean historical commit. + +### 3.2 Fresh executable baseline + +The following command was run with task outputs forced to rerun: + +```bash +cd src +./gradlew test --rerun-tasks --console=plain --no-daemon +``` + +Result: + +- build successful in 2m 26s; +- 1,661 JUnit/Jqwik/Spock test invocations; +- 8 skipped invocations; +- 0 failures and 0 errors; +- 275 emitted JUnit XML suites; +- 372 Java test-tree source files and 3 Groovy test-tree source files; +- `domain-core:test` was `NO-SOURCE`; +- the explicit Redis service lane was not part of this result. + +Docker was available during this run, so current PostgreSQL and MinIO tests ran. The successful run +does **not** prove they would fail closed on a runner without Docker. + +### 3.3 Evidence grades used in this design + +| Grade | Meaning | +| --- | --- | +| A | Fresh executable repository evidence or deterministic source/config inspection | +| B | Official product/framework documentation | +| C | Design inference tailored to this repository | +| D | Organization-specific value still requiring an owner decision or measured baseline | + +Provider support versions, CI duration budgets, production SLO thresholds, and cloud topology are +grade D until the adopting service declares them. This design does not fabricate those values. + +## 4. Current state + +### 4.1 Strong foundations to retain + +- Exactly 19 production leaves and allowed dependency edges are fail-closed in + `modules.json`, settings, and Gradle verification. +- ArchUnit has positive controls rather than only vacuous clean checks. +- Core modules use framework-light JUnit/AssertJ dependencies. +- There are MVC, JPA, GraphQL, gRPC, full-context, OpenAPI snapshot, property-based, PostgreSQL, + MinIO, and concurrency tests. +- `sampleOffTest` proves production can be compiled and tested without the example portfolio. +- `quarantineTest` is non-blocking, while registry drift and a 14-day sunset remain blocking. +- Dependency locks, format/static analysis, environment registry, public path snapshot, and + security scanning already feed CI. +- The Docker runtime already has non-root, read-only filesystem, memory, shutdown, and health + contracts that a future artifact lane can exercise. + +### 4.2 Material gaps + +| Gap | Repository evidence | False conclusion it permits | +| --- | --- | --- | +| Mixed execution environments | Unit, slice, Spring context, PostgreSQL, and MinIO tests mostly share `test` | "`test` is fast and hermetic" or "`test` always verifies providers" | +| Conditional provider skip | `disabledWithoutDocker` and `Assumptions.assumeTrue(Docker...)` are present | "CI verified PostgreSQL/MinIO" when it may have skipped | +| Redis lane outside CI | `redisServiceTest` is excluded from default `test`;

It must not add a +production dependency edge to `modules.json`. + +### 8.2 Source layout + +Only source sets that a leaf actually needs are created. + +```text +src/<leaf>/ + src/main/java/ production + src/test/java/ deterministic unit/component/slice/architecture + src/testFixtures/java/ optional reusable test-only port contract kit + src/integrationTest/java/ disposable real service/driver/protocol + src/migrationTest/java/ optional historical migration lifecycle + +src/app-bootstrap/ + src/systemTest/java/ optional black-box harness with no production classes + +qa/ + performance/ k6/JMH entrypoints and versioned workloads + security/ DAST configuration and safe target policy + system/ shell/container harness when Java adds no value +``` + +`qa/` is verification infrastructure, not a Gradle production module and not a Clean Architecture +leaf. A Java `systemTest` must deliberately avoid `sourceSets.main.output` on its compile/runtime +classpath; it can know public HTTP/gRPC schemas or generated client contracts, but it must not call +an application bean, repository, controller method, or test-only boot class. + +### 8.3 Task contracts + +| Task | Allowed infrastructure | Failure contract | +| --- | --- | --- | +| `<leaf>:test` | Heap/in-process resources, `@TempDir`, ephemeral loopback server | Fails on Docker/Internet/manual-service dependency, fixed port, zero discovery where the leaf declares required tests, or ordinary assertion failure | +| `<leaf>:integrationTest` | Testcontainers with pinned provider images and optional Toxiproxy | Fails before discovery if Docker is unavailable; fails on unexpected skip, zero discovery, leaked container, or provider failure | +| `<leaf>:migrationTest` | Disposable DB plus checked-in versioned fixtures | Fails on empty install, supported-version upgrade, validation, data invariant, lock/error-budget, or cleanup failure | +| `app-bootstrap:systemTest` | Built candidate JAR/image and disposable external services | Fails if the exact candidate cannot start, become ready, expose its build identity, or complete critical black-box probes | +| root `test` | Lifecycle aggregation only | Depends on every registered deterministic leaf task and remains Docker-free | +| root `integrationTest` | Lifecycle aggregation only | Depends on every suite marked required for the selected profile | +| root `releaseCandidateCheck` | Local/single-runner lifecycle for quality, required integrations, and candidate smoke | Reproduces the repository verification bundle; it cannot aggregate independent CI jobs or workflows | + +The root lifecycle tasks are not themselves `Test` tasks and must not manufacture an empty green +report. Local developers may select a leaf lane, while CI selects the registered aggregate. +`releaseCandidateCheck` is a local Gradle lifecycle only. A GitHub Actions `release-gate` becomes +the CI fan-in only after every blocking workflow is exposed through `workflow_call` and invoked as +a job in one caller workflow, because `needs` cannot reference a job in another workflow. Until +that migration is complete, the branch-protection required-check union—not the current +`release-gate` alone—is the enforcement authority. + +### 8.4 Test-suite registry + +`src/config/architecture/modules.json` remains the production dependency SSOT. Add a separate, +fail-closed `src/config/testing/test-suites.json` for verification execution. It references module +IDs from the architecture registry rather than duplicating their paths or Gradle coordinates. + +Conceptual shape: + +```json +{ + "schema_version": 1, + "allowed_test_dependencies": [ + { + "from_module_id": "adapter-outbound-persistence-jpa", + "to_module_id": "application-core", + "scope": "test-fixtures" + } + ], + "providers": { + "postgresql-16": { + "container_image": "postgres:<approved-tag>@sha256:<declared-digest>", + "topologies": ["standalone"] + } + }, + "suites": [ + { + "id": "persistence-jpa-postgresql", + "owner_module_id": "adapter-outbound-persistence-jpa", + "task": "integrationTest", + "source_set": "integrationTest", + "boundary": "provider-integration", + "purposes": ["contract", "transaction", "migration-baseline"], + "required_services": ["postgresql-16"], + "required_in": ["pull-request", "main-merge"], + "skip_policy": "none" + } + ] +} +``` + +The digest above is intentionally a placeholder, not a proposed image selection. Implementation +resolves and reviews actual supported image tags/digests. A movable tag such as +`postgres:16-alpine` is insufficient release evidence because its bits can change without a source +change. + +`verifyTestSuiteRegistry` must fail when: + +- an owner module is unknown or lacks the declared source root/task; +- a suite ID, provider alias, boundary, purpose, or required cadence is unknown; +- a required suite discovers zero tests or has an unapproved skip; +- a required CI suite has no corresponding job/fan-in entry; +- a registered source set has no registry entry, or a registry entry is never selected; +- production configurations depend on a test fixture; +- test-only cross-leaf dependencies are not explicitly declared and allowed; +- quarantine scanning omits Java/Groovy or a registered source set. + +The suite registry describes execution, not individual test classes. Class discovery counts and +skip outcomes are emitted at runtime and compared with the suite policy. + +The suite registry is the SSOT for suite ownership, test-only edges, and required cadence. The +existing gate matrix remains the SSOT for the complete set of blocking CI jobs, including +non-Gradle and cross-workflow security jobs. CI configuration maps suite IDs to jobs; +`verifyTestSuiteRegistry` checks both directions so neither authority can silently drift. + +### 8.5 Dependency policy for Spring Boot 4 + +Spring Boot 4 modularized starters and test infrastructure. Each leaf declares only the focused +test support it owns—for example, MVC test support for the web leaf and data-JPA test support for +the JPA leaf—instead of the root adding Web MVC test infrastructure to every non-core leaf. The +classic umbrella test starter may remain during migration, but the destination classpath is +capability-specific. + +Baseline rules: + +- `domain-core`: JUnit/Jqwik/AssertJ only as behavior requires; +- `application-core` and `shared-contract`: JUnit/Jqwik/AssertJ and hand-written fakes; +- Spring slices: owning Boot 4 focused test starter only; +- Testcontainers modules and provider drivers: `integrationTestImplementation` only; +- system harness: protocol client/assertion libraries only, never production output; +- strict dependency locks include every new resolvable test configuration. + +This repository is pinned to Spring Boot 4.0.0, whose dependency management currently resolves +JUnit 6.0.1 and Testcontainers 2.0.2. Examples written for Boot 3 or Testcontainers 1.x are not +copied mechanically. A Boot patch uplift is a separate compatibility change with its own evidence. + +## 9. Boundary contracts and reusable fixtures + +### 9.1 Contract-kit pattern + +When `application-core` owns a port, it may publish a test-only abstract contract from +`testFixtures`. Each outbound adapter supplies a factory and runs the same behavioral examples +against its implementation. + +```text +application-core test fixture: CachePortContract + -> in-memory fake contract test + -> Redis adapter deterministic codec test + -> Redis adapter real-provider integration test +``` + +The contract kit should express only application-visible semantics: key validity, idempotency, +not-found behavior, expiry guarantees, error categories, and concurrency expectations that the +port actually promises. It must not import Redis, JPA, HTTP, Spring MVC, or persistence entity +types. + +Provider-specific behavior remains in the adapter suite. For example, a generic repository port +contract does not replace PostgreSQL tests for unique constraints, isolation, SQL-state +translation, locking, or outbox atomicity. + +### 9.2 Contract testing across process boundaries + +Use checked-in schema/snapshot compatibility while this repository is a single template: + +- OpenAPI and GraphQL schema snapshots; +- protobuf descriptor/binary compatibility; +- event schema/envelope compatibility; +- notification/webhook example payloads. + +Serialization tests for a `shared-contract` type live in the consuming web, gRPC, GraphQL, +messaging, or other adapter and use that adapter's production serializer. `shared-contract` stays +framework-free and does not acquire Jackson, Spring, transport, or provider test dependencies. + +Introduce one consumer-driven contract framework only when independently released consumers and +provider verification workflows actually exist. Spring Cloud Contract or Pact can distribute +examples, but neither proves a complete workflow, deployment correctness, authorization, or +provider performance. Running both without distinct consumers would add ceremony rather than +evidence. + +### 9.3 Test-double vocabulary + +Use names according to behavior: + +- **dummy**: required but unused value; +- **stub**: fixed answers; +- **spy**: records interaction; +- **fake**: working but simplified implementation; +- **mock**: expectation-driven interaction verifier; +- **simulator**: protocol-level substitute such as MinIO or a loopback HTTP server. + +Tests and reports must say which substitute was used. Calling MinIO “S3 E2E” or a hand fake “Redis +integration” is prohibited. + +## 10. Environment topology + +### 10.1 Environment matrix + +| Environment | Artifact/target | Data and services | Blocking purpose | Explicit limitation | +| --- | --- | --- | --- | --- | +| Developer/PR deterministic | Compiled classes | Heap, temp directory, ephemeral loopback | Fast behavior, slice, architecture, schema | No real provider or packaged artifact | +| PR provider integration | Compiled owning adapter | Disposable Testcontainers per job/run | Required provider/driver/transaction contract | Local container topology only | +| PR candidate system | Exact boot JAR/OCI digest built once | Disposable CI Compose stack, random ports | Startup, readiness, configuration, critical black-box path | Not managed cloud or production ingress | +| Main/merge candidate | Canonical OCI digest built from the protected merge commit | Required disposable providers plus system stack | Reverify the merged revision and create the only promotable candidate | A passing PR head is not evidence for a different merge commit | +| Nightly compatibility | Same candidate or main artifact | Version/topology matrix, faults, historical migration fixtures | Upgrade, resilience, supported-version breadth | Longer cadence delays feedback | +| Protected provider sandbox | Candidate adapter/application | Real cloud/provider tenant with least privilege | IAM/KMS/TLS/quota/control-plane compatibility | Still not production scale/data/topology | +| Staging/pre-production | Promotable immutable digest | Production-like deployment and sanitized synthetic data | Ingress, rollout, observability, safe DAST/load smoke | Configuration and traffic never perfectly equal production | +| Production | Promoted digest | Production control plane | Read-only/idempotent synthetic and rollback signal | No destructive test, load test, or chaos by default | + +An environment name is not evidence by itself. Each run records artifact digest, source revision, +suite registry version, provider/image versions, topology, feature flags, and sanitized +configuration fingerprint. + +### 10.2 Provisioning rules + +- Testcontainers owns leaf integration dependencies and their lifecycle. +- Spring Boot service connections are preferred when a supported container module exists; a + `GenericContainer` needs an explicit connection name or configuration mapping. +- Containers use exact reviewed tags and, for release evidence, digests. +- Testcontainers reusable-container mode is developer-only: it is experimental and must be off in + CI. +- CI workers use a supported Docker environment. “Docker unavailable” is a preflight failure for + a selected integration job, never a JUnit assumption. +- Compose is reserved for multi-process candidate-image/system evidence, not as the ordinary leaf + test dependency mechanism. +- Provider credentials are short-lived, least-privilege, masked, and issued only to protected + jobs. Fork pull requests cannot reach provider sandboxes. + +## 11. Test data, time, identity, and cleanup + +Every run receives a non-secret `TEST_RUN_ID`; parallel workers additionally include the Gradle +worker ID. That identity scopes every mutable resource: + +| Resource | Isolation key and cleanup | +| --- | --- | +| PostgreSQL | Database or schema per run/worker; explicit truncation or container disposal after commit/concurrency tests | +| MongoDB | Database per run/class; drop on completion | +| Redis | Run-specific key prefix; bounded TTL; never `FLUSHALL` on a shared target | +| Kafka/broker | Unique topic and consumer-group suffix; delete where supported or let disposable broker die | +| S3/MinIO | Bucket or prefix per run; version/delete markers included in cleanup | +| Filesystem | JUnit `@TempDir`; no repository-relative or developer-home mutable paths | +| HTTP/provider sandbox | Idempotency key and tenant/run namespace; compensating cleanup with an audit trail | + +Rules: + +1. Unit/component tests receive an injected fixed `Clock`, seeded random source, and deterministic + identifier generator where time/identity affects behavior. +2. Property-test and randomized-concurrency seeds are printed in XML/log evidence and can be + replayed. +3. Generated credentials exist only for the run, never in source, fixtures, snapshots, command + output, or uploaded logs. +4. Tests never use production data. A release migration rehearsal may use an approved, + de-identified, access-controlled snapshot with owner, retention, deletion, and audit policy. +5. Cleanup runs in `finally`/post-job even after failure. Cleanup failure is visible and does not + erase the original test failure. +6. Polling uses a bounded condition with a diagnostic timeout. `Thread.sleep` is not a + synchronization protocol. +7. A repository test never requires a developer's `.env.local`, persistent Compose volume, or + pre-existing localhost service. + +Rollback is an optimization, not a universal isolation guarantee. Tests that verify commit-time +constraints, listeners, outbox records, retries, concurrent transactions, or a real HTTP server +must commit deliberately and clean their data explicitly. + +## 12. Spring and JUnit execution hazards + +### 12.1 Transaction truth + +- `@SpringBootTest(webEnvironment = RANDOM_PORT)` runs server work on another thread and + transaction; a transaction on the test method does not roll back writes made by the server. +- A default `@DataJpaTest` rollback can hide deferred constraints, commit callbacks, and outbox + behavior. Important JPA tests explicitly `flush`, clear the persistence context, reload state, + and use an explicit commit test where the contract is commit-time. +- Preemptive timeout mechanisms can execute work on a different thread from Spring's + thread-bound test transaction and accidentally commit it. Use framework-aware/non-preemptive + timeouts for transactional tests, and capture a thread dump when a process-level deadline fires. + +### 12.2 Context cache + +Spring's test context cache is static within one JVM and has a finite default maximum. Excess +profiles, unique dynamic property functions, mock-bean declarations, and `@DirtiesContext` create +distinct cache keys or evict contexts. Forked JVMs cannot share the cache. + +The implementation should: + +- define a small named set of test context archetypes; +- reuse configuration and dynamic properties within an archetype; +- prefer hand fakes or explicit test configuration over per-class context mutation; +- report context cache statistics during optimization; +- avoid `@DirtiesContext` unless the test truly corrupts shared context state. + +Context-start failures must fail quickly rather than repeating the same expensive failure across +hundreds of classes. + +### 12.3 Parallel execution + +Parallelism is opt-in by suite: + +- pure unit/property tests may run concurrently after shared-static-state review; +- Spring tests using `@DirtiesContext`, per-test mock-bean mutation, shared database state, or + ordered lifecycle remain sequential; +- Testcontainers' JUnit integration does not promise parallel execution safety, so stateful + provider suites start sequentially and parallelize at the CI job/provider level first; +- JUnit resource locks protect unavoidable JVM-global resources such as timezone, system + properties, and singleton registries; +- all `Test` tasks receive an explicit timezone/locale, bounded task timeout, heap policy, and + deterministic parallel configuration. + +Static Testcontainers fields also need lifecycle review: a container stopped after a class can +leave a cached Spring context pointing at a dead service. Context-managed container beans or +well-scoped shared fixtures are safer when the context is reused. + +## 13. Provider qualification matrix + +The support policy must distinguish a protocol baseline from a production-readiness claim. + +| Capability | Required integration baseline | Conditional qualification for a claimed feature | Not established locally | +| --- | --- | --- | --- | +| PostgreSQL/JPA | Pinned PostgreSQL, Flyway, mappings, constraints, SQL-state translation, transaction/outbox/idempotency, representative query plan | Each supported major upgrade, lock/concurrency and managed-provider TLS/IAM | Multi-AZ failover, production cardinality/IO | +| MongoDB | Pinned real MongoDB, codecs, indexes, queries | Replica set for transactions/change streams; supported upgrade path | Atlas control plane, sharding/failover unless targeted | +| Redis | Pinned standalone Redis, Lua/functions, TTL, serialization, atomicity | ACL/TLS, Sentinel/Cluster, eviction, restart/failover when advertised | HA or cluster safety from standalone | +| HTTP client | Real loopback sockets, TLS fixture, pool/cancellation/deadline, Toxiproxy latency/reset | Corporate proxy/DNS/provider sandbox and supported JDK matrix | External API correctness from WireMock/stub | +| Messaging | Real supported broker, ack, ordering boundary, duplicate/redelivery, retry/DLT, schema | Broker version/topology, auth/TLS, restart/partition fault | End-user completion without a real consumer flow | +| Object storage | MinIO S3 protocol baseline, multipart/checksum/error mapping | AWS sandbox for IAM, KMS, versioning, presigned URL, lifecycle, throttling | AWS control-plane equivalence from MinIO | +| File server | Temp filesystem for path/journal rules | Each supported mount/filesystem, permissions, disk-full, crash recovery, multi-process fencing | Distributed consistency from local disk | +| Notification | Fake routing/template plus local SMTP/webhook receiver | Provider sandbox for auth, throttling, timeout, receipt/webhook mapping | Human inbox placement/deliverability | +| Web | MockMvc slice plus real embedded HTTP component | Proxy headers, TLS, compression, body/connection limits | Ingress/WAF behavior | +| gRPC | Real loopback feature RPC with auth/deadline/cancellation | TLS/mTLS, proxy/load balancer, streaming/backpressure | Mesh/provider behavior | +| GraphQL | Schema/resolver/security/complexity tests | Real HTTP/WebSocket transport, subscriptions, DataLoader query count | Arbitrary client query safety | +| WebSocket | Real handshake/STOMP/origin/auth/reconnect | Broker relay, slow consumer/backpressure, proxy idle timeout | Durable exactly-once delivery | + +This matrix becomes executable only after the adopting project declares which optional capability +and topology it supports. Unclaimed optional features remain documented exclusions rather than +permanently skipped tests. + +## 14. Migration verification + +Database migration evidence has three distinct paths: + +1. **Empty install**: an empty supported database migrates to current and the application starts. +2. **Upgrade**: a checked-in fixture from every supported upgrade baseline migrates to current, + preserves named invariants, and passes Flyway validation. +3. **Compatibility window**: when rolling deployment is supported, old and new application + versions can coexist through the declared expand/contract window. + +Migration fixtures contain structure and synthetic boundary data, not copied production records. +Each fixture declares source application and schema versions, source release artifact digest, +database engine and migration-tool versions, reproducible generation command, fixture and migration +checksums, invariant manifest, and retirement rule. Upgrade fixtures are generated or verified +against the immutable historical release's migration artifacts; a hand-edited dump without that +provenance is not release evidence. + +The release lane also measures migration duration and lock behavior on a representative synthetic +scale. Its threshold is derived from the deployment error budget. A successful small-container +migration cannot establish production lock duration or permit an automatic downgrade. Rollback is +usually application roll-forward plus data repair; destructive database downgrade requires a +separately designed and tested policy. + +`migrationTest` should not be created merely to rename existing JPA integration tests. Add it when +historical fixtures or destructive lifecycle require separate retention, permissions, cadence, or +timeouts. + +## 15. Candidate artifact and system environment + +### 15.1 Build once, test the promotable bits + +For each source revision, CI creates the boot JAR once after the required deterministic and +provider verification for that revision. +The image build copies that exact prebuilt JAR rather than invoking `bootJar` again, records both +SHA-256 digests and their provenance relationship, and treats the OCI digest as the canonical +promotable artifact. System, security, staging, and promotion reuse that digest; a later job must +not rebuild “equivalent” bits. + +The current `src/Dockerfile` runs `bootJar` inside the image build, so this guarantee does not exist +yet. Phase 3 must refactor the Docker build input or explicitly choose an image-only build pipeline +before claiming artifact identity. + +The current local `bootstrap`/`bootstrapSmoke` workflow is useful developer evidence but cannot be +the required system gate unchanged. Add a CI-only `docker-compose.test.yml` or generated override: + +- unique Compose project name derived from `TEST_RUN_ID`; +- generated credentials and random host ports; +- no `.env.local`, developer secrets, named persistent volumes, or restart policy; +- read-only/non-root runtime constraints retained; +- deterministic health/readiness deadlines; +- logs, inspect output, resource usage, and sanitized environment captured before teardown; +- `down --volumes --remove-orphans` in an unconditional cleanup step. + +### 15.2 Minimum black-box probes + +The system harness observes application behavior only through public network interfaces. It may +use the Docker/orchestrator control plane for process lifecycle, signal delivery, dependency fault +injection, digest inspection, and diagnostic collection; it must never call internal beans, +controllers, or repositories. It verifies: + +- process/container starts under production-like profile and filesystem/user constraints; +- liveness and readiness have distinct semantics and readiness waits for required dependencies; +- build revision/image digest and effective non-secret feature profile are observable; +- malformed, unauthenticated, unauthorized, oversized, and unsupported-content requests fail with + the public error contract and no sensitive disclosure; +- graceful shutdown removes readiness first, drains bounded in-flight work, and exits within the + declared platform budget; +- one representative critical flow is exercised for each enabled inbound protocol, with state + verified through a public read path or provider observation rather than an internal repository; +- required migration and dependency-loss behavior match the declared startup/readiness policy. + +The representative flow is not selected by the template in the abstract. An adopting application +must name business-critical journeys and their data cleanup contract. + +## 16. Security, resilience, observability, and performance + +### 16.1 Security + +Security evidence is layered: + +- unit tests for authorization policy and redaction; +- transport slice tests for authentication mapping, CSRF/CORS/origin rules, validation, and error + disclosure; +- system negative tests through the full filter chain and candidate runtime; +- dependency/secret/container/static scanning; +- authenticated DAST against an ephemeral or staging target; +- manual threat-model and abuse-case review for controls scanners cannot infer. + +The control catalog maps to a selected OWASP ASVS version; test techniques may reference OWASP +WSTG. Scanner success is not a proof that the application has no vulnerability. Production +security synthetics are non-destructive and explicitly allowlisted. + +### 16.2 Resilience + +Pure tests verify retry budgets, backoff calculations, idempotency decisions, circuit-state +transitions, and cancellation propagation. Provider integration injects explicit socket latency, +connection reset, timeout, dependency restart, duplicate delivery, and partial response using a +fault proxy or provider control. + +Every scenario asserts both the caller result and bounded side effects: + +- total attempts and elapsed budget; +- no retry of forbidden/non-idempotent operations; +- connection/thread/resource recovery; +- correct metrics/traces/log redaction; +- readiness degradation or continued service according to policy; +- no duplicate durable outcome where idempotency is promised. + +Chaos is not a synonym for randomness. Fault, scope, duration, expected steady state, abort +condition, and cleanup are versioned inputs. Broad production chaos is out of scope until the +organization has an owner and safety process. + +### 16.3 Observability + +Tests use Micrometer's observation test facilities or an in-memory registry to assert semantic +names, low-cardinality tags, error/timeout status, trace propagation, and secret/PII exclusion. +Candidate system tests confirm actuator exposure policy and correlation across a real inbound to +outbound call. + +They cannot establish dashboard correctness, alert routing, collector capacity, or production +cardinality. A staging/post-deploy observability check must inject a known signal and confirm it +reaches the configured backend/alert path. + +### 16.4 Performance + +- JMH is used for microbenchmarks of isolated CPU/allocation-sensitive algorithms only. +- k6 or an equivalent external driver targets the immutable system artifact for latency, + throughput, and error-rate thresholds. +- thresholds are derived from an agreed SLO and workload model, not invented from a shared PR + runner. +- PR may run a small non-gating regression smoke; blocking load/soak runs on controlled, + comparable runners nightly or before release. +- reports record warm-up, JVM flags, CPU/memory limits, dataset/cardinality, concurrency, request + mix, duration, provider topology, and artifact digest. + +JUnit wall-clock assertions on a busy shared runner do not qualify as performance tests. A passing +small load test does not prove maximum production capacity. + +## 17. Determinism, flaky tests, and diagnostics + +The existing 14-day quarantine remains an emergency containment mechanism, not a second backlog. +Extend it to every registered source set and Java/Groovy. A quarantine entry requires owner, +tracking issue, symptom, first/last observed time, deterministic reproduction evidence, and expiry. + +Policy: + +- a required gate never converts an infrastructure error or unexpected skip into quarantine; +- blind auto-retry cannot turn the first failure green; +- one diagnostic rerun may be retained, but the job remains failed and preserves both attempts; +- repeatedly failing tests are fixed or removed only with a replacement evidence argument; +- clock, random seed, port, ordering, locale, timezone, thread scheduling, and external resource + ownership are controlled explicitly; +- process-level timeouts collect thread dump, test task state, container state, and last logs before + termination. + +Each failed provider/system job uploads: + +- JUnit XML and HTML report; +- source revision, artifact and provider image digests; +- suite ID, seed, timezone/locale, Java/Gradle/OS/Docker fingerprint; +- sanitized application/container logs and container inspection; +- thread dump and resource snapshot on hang/timeout; +- migration/provider diagnostics relevant to the owning suite. + +Secrets and payloads are redacted before artifact upload. Retention follows the repository's +security and incident policy. + +## 18. Coverage and test effectiveness + +Add separate JaCoCo execution data and aggregate reports for deterministic and integration lanes. +Do not merge them so early that a provider test hides a missing unit-level decision test. + +Adoption sequence: + +1. publish a baseline without a blocking percentage; +2. inspect packages/classes with meaningful production behavior but no exercised branch; +3. require named risk scenarios for changed domain/application policy and changed adapter + boundaries; +4. introduce a changed-code coverage ratchet once the baseline is stable; +5. apply package-specific floors only when owners understand generated code, DTOs, configuration, + and unavoidable branches; +6. run mutation analysis nightly on pure `domain-core`/`application-core` policy, not on the whole + Spring/container stack. + +Coverage means code was executed; it does not prove the assertion would detect a defect. Mutation +survival is stronger diagnostic evidence but still does not replace missing business scenarios, +contract examples, or production topology tests. + +## 19.

This repository is small enough that correctness of +the evidence graph is more valuable. Optimize only from measured duration/cache data and keep a +periodic full run. + +PR artifacts are diagnostic and unpromotable. A protected main/merge lane reruns all required +deterministic and provider suites against the actual merge commit, builds the canonical JAR/image +once, runs migration and candidate smoke against that digest, and retains its provenance.

Revalidate registries, dependency locks, deterministic tests, and required provider suites on + the protected merge commit. +2. Build the preverified JAR once, copy it into the OCI image, and publish immutable provenance. +3. Run migration compatibility and black-box system smoke against the published digest. +4.

The candidate application itself is tested as an image in the system lane. + +## 20. Evidence ledger and claim discipline + +Every externally meaningful capability should have a short ledger entry in generated test +documentation: + +| Field | Example kind of value | +| --- | --- | +| Claim | “Repository save and idempotency are atomic on supported PostgreSQL” | +| Owner | `persistence-jpa` | +| Evidence suites | unit port contract, PostgreSQL integration, migration path, candidate smoke | +| Real/replaced | real PostgreSQL; application transport may be replaced in leaf integration | +| Environment/version | image digest/topology or provider sandbox identifier | +| Last result/artifact | CI run and immutable report link | +| Known exclusions | managed failover, production cardinality | +| Expiry/requalification | provider/app version or time-based trigger | + +The following phrases are forbidden unless the corresponding evidence exists: + +- “E2E tested” for a slice, mocked port, or test-only application; +- “production-ready Redis” after only a fake or standalone path when Cluster/Sentinel is claimed; +- “S3 compatible” from SDK mocks alone, or “AWS verified” from MinIO; +- “migration safe” after only empty-database startup; +- “performance proven” without an artifact, workload, controlled environment, and threshold; +- “secure” because scanners are green; +- “all tests passed” when a selected required suite skipped, discovered zero tests, or did not run. + +## 21. Incremental rollout + +### Phase 0 — classify and freeze the baseline + +- approve this taxonomy and capability/support claims; +- add the test-suite registry schema and verification task; +- record current task/class/discovery/skip/duration/context-cache baseline; +- rename misleading `E2E`/`IT` classes without changing behavior; +- declare intentional skip reasons and owners. + +Exit: every current suite is assigned an owner, boundary, environment, purpose, and CI policy. + +### Phase 1 — separate deterministic and provider lanes + +- create explicit `integrationTest` convention/source set; +- move existing PostgreSQL and MinIO tests without changing assertions; +- migrate the Redis real-service lane into the same model and make it CI-required when Redis is an + enabled capability; +- remove Docker assumptions/`disabledWithoutDocker` from required provider suites; +- make `test` Docker-free and add discovery/skip enforcement; +- update strict dependency locks. + +Exit: `test` succeeds on a runner with no Docker, while selected `integrationTest` fails preflight +without Docker and executes real providers when Docker exists. + +### Phase 2 — close capability gaps + +- move provider semantics from `app-bootstrap` to owning leaves; +- add real MongoDB/broker and missing feature-transport integrations for enabled capabilities; +- create application-owned reusable port contract fixtures; +- add provider/version/topology policy and fault cases; +- keep composition-only checks in `app-bootstrap`. + +Exit: each enabled production capability has deterministic contract evidence and at least its +declared provider baseline. + +### Phase 3 — immutable candidate system gate + +- build candidate once; +- add disposable CI Compose/system harness and production-like health/readiness/shutdown checks; +- name critical reference/sample journeys; +- feed all blocking jobs into the existing gate matrix. + +Exit: CI proves the promotable image boots and crosses its declared public/provider boundaries. + +### Phase 4 — migration and non-functional qualification + +- add historical migration fixtures and rolling compatibility where relevant; +- add security mapping/DAST, Toxiproxy faults, observation assertions, controlled load/soak; +- publish split JaCoCo baseline and targeted mutation reports; +- add protected provider sandboxes only for advertised managed capabilities. + +Exit: release claims have owned, reproducible evidence and explicit exclusions. + +### Phase 5 — measured optimization + +- analyze duration, context-cache churn, container startup, and runner utilization; +- tune job sharding and safe unit parallelism; +- introduce changed-code coverage ratchets and evidence expiry; +- consider Gradle JVM Test Suite adoption only if it materially simplifies the proven model. + +Exit: optimization preserves the fail-closed evidence graph and is backed by before/after data. + +## 22. Acceptance criteria + +The test-environment implementation is complete only when all of the following hold: + +1. `modules.json` still registers exactly 19 production leaves and no new forbidden production + dependency edge exists. +2. Every test suite is registered to one owning leaf, one execution environment, and at least one + verification purpose. +3. `./gradlew test` is deterministic and succeeds without Docker, Internet, manual services, + `.env.local`, persistent volume, or fixed port. +4. Selecting a required integration suite with Docker unavailable fails before JUnit discovery. +5. Required suites fail on zero discovery and unexpected skip, while explicitly approved + conditional/meta-test skips remain visible. +6. Testcontainers dependencies are absent from ordinary deterministic source-set classpaths. +7. Provider images/versions/topologies and compatibility exclusions are declared and emitted in + reports. +8. Mutable data is namespaced per run/worker and cleanup is verified after success and failure. +9. Candidate system tests observe application behavior only through public ports; lifecycle and + fault controls stay in the external orchestrator plane. The canonical OCI provenance identifies + the exact prebuilt JAR it contains. +10. Migration evidence includes empty install and every declared upgrade baseline; rolling + compatibility is tested if advertised, and historical fixtures have immutable release + provenance. +11. All blocking work is represented inside one caller as ordinary or reusable-workflow jobs; its + `release-gate` cannot stay green if one is missing or renamed, and the only promotable candidate + was built and reverified from the protected main merge commit. +12. Reports preserve first failure, seed, environment fingerprint, artifact/provider digests, and + sanitized diagnostics. +13. Security, resilience, observability, and performance claims list the specific environment and + exclusions they cover. +14. Test fixtures cannot become production dependencies, and adapter/provider types cannot leak + into core contract kits. +15. Focused leaf verification, aggregate deterministic/integration checks, candidate smoke, and + architecture gates have fresh executable evidence. +16. The LLM Wiki branch note records implementation decisions, commands, failures, and evidence + grade before completion is claimed. + +## 23. Expected implementation impact + +The design anticipates changes in these areas; this document does not yet authorize or implement +them: + +- `src/config/testing/test-suites.json` and its schema; +- `src/build.gradle` or a build-logic convention for source sets/tasks/verification; +- focused leaf Gradle dependencies and lockfiles; +- relocation/rename of existing tests without changing their initial behavior; +- provider fixtures and port contract test fixtures; +- a new `.github/workflows/ci-release-candidate.yml` caller/fan-in workflow; +- `workflow_call` entrypoints in `ci-quality-gates.yml` and `dependency-vulnerability.yml`; +- `.github/ci-gate-matrix.yml` plus its caller/reusable-job mapping validation; +- `src/Dockerfile` or its build context so the image consumes the exact prebuilt boot JAR; +- a CI-only disposable Compose override/system harness; +- `qa/security`, `qa/performance`, and evidence/report publishing; +- contributor documentation for choosing an owner, source set, and local command. + +Explicit non-goals for the first implementation: + +- adding a twentieth production module; +- changing a business port or production dependency direction merely for testing convenience; +- immediately supporting every optional provider topology; +- enforcing an arbitrary global coverage percentage; +- running destructive DAST/load/chaos against production; +- using cloud credentials in untrusted pull-request jobs; +- replacing focused leaf tests with a single slow system suite. + +## 24. Owner decisions required before implementation + +The architecture can be implemented incrementally, but these values cannot be derived honestly +from the skeleton: + +1. Which adapters are mandatory in the default template CI versus optional capability profiles? +2. Which PostgreSQL, MongoDB, Redis, broker, object-storage, and JDK versions/topologies are + supported? +3. What are the maximum PR and release-lane budgets, runner topology, artifact retention, and + quarantine service-level agreement? +4. Which public journeys are release-critical when the sample portfolio is disabled? +5. Is rolling application/schema compatibility promised, and for how many released versions? +6. Which managed-provider sandboxes exist, who owns cost/credentials/cleanup, and which claims do + they qualify? +7.

Rejected. + +### Approach B: patch each symptom in place + +Condition the ArchUnit rule on a sample flag, copy only the two currently missing registry files, +and add the three currently missing SpotBugs JARs manually.

Selected. + +## Architecture Test Ownership + +`adapter-outbound-objectstorage` owns rules about the public types of its production adapter methods. +The rule moves out of `app-bootstrap` and runs in the Object Storage module's normal test suite. +It remains strict: the Object Storage module must contain matching production classes and the rule +must not globally allow an empty `should` clause. + +`app-bootstrap` continues to own cross-module rules. Its sample-off suite verifies that production +composition works without `sample-portfolio`; it does not require sample-only leaves to be present. +The existing module registry and dependency verification remain the SSOT for leaf coverage. + +## Gradle Wrapper Integrity + +Gradle 9.0.0 remains the selected version for this refactoring. The wrapper scripts, properties, and +JAR are regenerated from Gradle 9.0.0 in a trusted environment. The official 9.0.0 binary +distribution SHA-256 is recorded as: + +```text +8fad3d78296ca518113f3d29016617c7f9367dc005f932bd9d93bf45ba46072b +``` + +The wrapper properties are one exact ordered eight-line byte contract, preventing Java Properties +duplicate-key, separator, escape, and continuation semantics from overriding the reviewed values. +The complete six-file workflow path set and every workflow's SHA-256 are embedded as a reviewed +byte lock in the verifier. This is the primary completeness boundary: YAML has aliases, encoded +keys, duplicate-key overrides, custom shells, and other equivalent representations that a partial +Bash parser cannot safely model. Any workflow addition, removal, rename, symlink replacement, or +byte change fails until the complete workflow diff is intentionally reviewed and the sorted lock +is refreshed in the same change. + +The restricted block-style workflow grammar remains defense in depth and supplies actionable +diagnostics for ordinary drift. Every Gradle-running job uses an unconditional validation step +with a stable ID and the action pinned by commit SHA. Checkout and validation precede every Gradle +invocation, not only the first; a cleanup/sanitizer step that intentionally uses `always()` also +requires the validation step's successful outcome. This is consistent with the repository's +existing pinned `actions/setup-java` policy and prevents wrapper failure from being bypassed by +step conditions. + +## Docker Configuration Contract + +Both Docker build dependency-cache stages preserve the repository layout with `WORKDIR /build/src` +and copy the complete `config/**` tree before invoking Gradle. The parent `/build` is therefore the +repository root expected by registry `source_path: src/**` entries. This is intentional: Gradle +configuration registries and their repository-relative path base are build inputs, while the +registry's exact internal file list may evolve. + +Git revision validation no longer runs unconditionally while the build script is being configured. +A root-owned resolver is invoked once from each root evidence action or leaf evidence test's +root-suite completion action; eager scalar evidence properties are removed. Only evidence-producing +tasks resolve the checkout revision during their execution. Docker builds provide +`-PgitRevision=<40 lowercase hex>` and do not copy `.git` into the image context. + +The boot JAR path is obtained from Gradle's archive output contract rather than selecting the first +filesystem match. The final images retain the existing digest-pinned base image, non-root user, +read-only root filesystem, and JRE-only runtime. + +## SpotBugs and Gradle 10 Compatibility + +Every SpotBugs task analyzes a named source set and receives that source set's runtime classpath as +its auxiliary analysis classpath, excluding its own compiled output. Custom test source sets are +covered by the same rule. No production dependency scope is widened merely to silence SpotBugs. + +Missing-analysis-class output is treated as a gate failure. The clean gate must produce zero +`classes needed for analysis were missing` messages. + +The observed Gradle 10 deprecation is removed by capturing the application-core project during +configuration instead of calling `Task.project` from the task action. The dependency-purity gate +still traverses that project's configurations during execution, so it explicitly opts out of the +configuration cache rather than claiming serializable declared inputs it does not have. + +## Error Handling and Failure Semantics + +- sample-off fails only for a real production composition or architecture violation; +- an empty Object Storage rule in its owning module is a test failure; +- a wrapper JAR or distribution checksum mismatch fails before Gradle build logic executes in CI; +- missing Docker configuration input fails with a named build-contract test rather than an opaque + settings error; +- invalid or absent `gitRevision` fails only an evidence task that requires it; +- SpotBugs missing classes fail static analysis instead of producing a successful partial report. + +## Verification Design + +The implementation follows red-green-refactor.

GraphQL, gRPC, WebSocket, and Mongo remain in this state. +- Test fixtures and custom qualification configurations do not change production membership. + +Settings validation is fail-closed for missing, duplicate, or unknown membership names. A Gradle +verification task compares the registry to both composition roots and is part of `check`. + +## Explicit Qualification Composition + +`app-bootstrap` owns a `conditionalTransportTest` source set whose classpath explicitly includes +the three opt-in leaves. It proves that the opt-in artifacts resolve together while the registry +still declares them absent from both default runtime graphs. It is evidence composition, not a new +production dependency edge. + +The root registers exact qualification `Test` tasks for GraphQL, gRPC, and WebSocket. Each task: + +- names required test classes rather than broad discovery; +- fails on no match or no discovery; +- always reruns in UTC; +- fails if the root suite reports any skipped test. + +An aggregate `conditionalTransportQualification` task depends on the composition contract and all +three exact lanes. CI invokes it explicitly from the existing release-blocking quality job, and the +gate matrix records the task. + +## gRPC P1 Boundary + +gRPC activation becomes explicit and local-only until a later TLS/mTLS design exists: + +- `enabled=false` and `reflectionEnabled=false` are defaults; missing properties create no runner, + health manager, reflection service, or listener. +- The current insecure credential mode requires an explicit local-development override and a + loopback bind address. Non-loopback insecure bind fails startup. +- Feature services require a caller-supplied authentication policy/interceptor. Missing or invalid + metadata returns stable `UNAUTHENTICATED`; valid metadata reaches the service. +- Health remains a local lifecycle probe; reflection is a separate explicit flag. +- The error interceptor wraps `ServerCall.close`, so handler throws, listener throws, ordinary + `responseObserver.onError`, and raw `StatusRuntimeException` all pass the same sanitizer. + Recognized `ApiErrorCarrier` causes produce stable code/category trailers; unrecognized status + descriptions become fixed `INTERNAL_ERROR` with no raw diagnostic. + +A real ephemeral Netty unary service verifies authentication, reflection-off, all error paths, and +sentinel redaction. TLS/mTLS, external bind, deadlines, streaming, and protobuf compatibility are +P2 and remain unclaimed. + +## GraphQL P1 Boundary + +GraphQL remains classpath-selected: its absence from the default runtime is the disable mechanism, +and the qualification classpath is the explicit opt-in mechanism. The wire lane starts a real +random-port MVC server and crosses HTTP JSON, Spring Security, and CORS. + +It verifies unauthenticated rejection, authenticated health success, allowed/disallowed origins, +GraphiQL disabled, production-style introspection disabled, stable carrier errors, unknown errors, +and absence of distinct secret sentinels from the complete response body. The existing resolver is +changed only if a failing wire contract proves unsafe behavior. + +Feature schema/resolvers, field authorization, depth/cost, persisted queries, DataLoader, schema +compatibility, and subscriptions remain P2. + +## WebSocket P1 Boundary + +WebSocket gains `ca-skeleton.websocket.enabled=false`; both configuration and broadcaster are +conditional. Enabled settings reject wildcard/blank origins and invalid endpoint/destination +shapes. + +The inbound channel requires an authenticated handshake principal, permits subscription only to +the configured server topic, permits authenticated application sends under `/app/**`, and rejects +client sends to `/topic/**`. A custom STOMP error handler emits only a fixed client-safe code. + +The broadcaster no longer serializes arbitrary `@DomainEvent` objects. It consults an explicit +projection allowlist; an event without exactly one projection is not sent. Projection output is a +bounded primitive map, not the domain object graph. + +A real random-port WebSocket/STOMP lane verifies disabled absence, origin/auth/connect/subscribe, +server push, broker-send rejection, error redaction, and no projection/no broadcast. The simple +broker remains local/R1 only; broker relay, cross-node durability, replay, backpressure, and a +domain-specific versioned projection catalog remain P2. + +## Documentation Truthfulness + +Leaf READMEs and CLAUDE files describe only code that exists. Sample GraphQL schemas, gRPC services, +and WebSocket publishers are future adoption examples, not current runtime features. Each document +states the activation switch, exact P1 evidence, and unimplemented P2 limits. + +## Non-Goals + +- adding any of the three leaves to a shipped default runtime; +- adding a production project dependency edge outside the registry; +- claiming production readiness from local loopback/simple-broker tests; +- implementing sample feature APIs or domain payloads; +- staging, committing, amending, or pushing changes. diff --git a/docs/superpowers/specs/2026-08-02-p2-verification-governance-refactoring-design.md b/docs/superpowers/specs/2026-08-02-p2-verification-governance-refactoring-design.md new file mode 100644 index 0000000..94d58c3 --- /dev/null +++ b/docs/superpowers/specs/2026-08-02-p2-verification-governance-refactoring-design.md @@ -0,0 +1,79 @@ +# P2 Verification Governance Refactoring Design + +## Goal + +Remove the remaining fail-open verification paths without changing production behavior or adding +unadopted runtime capabilities.

Missing +Docker or OpenSSL is a hard failure, not a skip. + +The custom source set needs the Spring Session API at compile time.

Fix behavior defects at their source before applying any suppression. +2. Use suppression only where a framework signature, identity invariant, intentional violation + fixture, or approved compatibility seam makes the warning inapplicable. +3. Scope every suppression to the smallest class, method, field, constructor, or fixture that + explains it, with a nearby rationale. +4. Replace deprecated third-party APIs with their typed current equivalents and verify behavior, + not only compilation. +5. Capture expected-negative diagnostics and assert them exactly; never discard stderr globally. +6. Add blocking gates only after the current warning inventory is clean. + +## Component Design + +### 1. Real behavior defects + +#### Locale-independent identifiers + +Use `Locale.ROOT` for security roles, notification configuration keys, repository ACL names, and +test comparisons. Add Turkish-default-locale regressions that restore the original default locale +in `finally`: + +- `JwtToAuthenticatedPrincipalConverter`: `admin` must always become `ROLE_ADMIN`; +- `RoutingNotifier`: diagnostic keys for `EMAIL` must remain `app.notification.routes.email...`; +- `RepoStatsAclMapper`: `IDEA/Repo` must normalize to `idea/repo`. + +This is a correctness fix: the current code can generate dotless/dotted Turkish-I variants in +authorization and operational identifiers. + +#### Quote-aware ETag list parsing + +Do not replace `String.split(",")` with another delimiter-only splitter. A comma is legal inside a +quoted opaque entity tag. `ETags` will use a small scanner that: + +- splits only on commas outside a quoted string; +- preserves weak-tag prefixes and the existing trimming behavior; +- treats malformed/unclosed quotes as non-matching input rather than guessing a token; +- preserves wildcard and ordinary multi-value behavior. + +Regressions cover a single comma-bearing tag, a mixed list containing a weak comma-bearing tag, +ordinary lists, wildcard, stale values, blank input, and malformed quoting. + +#### Asynchronous and cleanup failures + +- `AsyncGracefulShutdownBehaviorTest` retains the returned `Future<?>` and observes `get()` so a + background assertion or exception cannot disappear. +- Outbox test cleanup methods propagate or wrap resource-destruction failures with the original + cause instead of using empty catches. +- Tests use fixed dates, UTF-8, and explicit locale rather than host defaults. + +### 2. Production warning cleanup with preserved invariants + +#### Redis primitive ownership + +`RedisPrimitiveInvocation` intentionally requires descriptor object identity. Value equality would +admit a descriptor created by another catalog and weaken the closed-catalog invariant. Keep the +reference comparison, add an exact constructor-level `ReferenceEquality` suppression, and add a +regression proving value-equal but non-identical cross-catalog descriptors are rejected. + +Qualify both nested `ExpectedKind` types with their enclosing record names rather than renaming the +types. This removes `SameNameButDifferent` without changing bytecode or package-local consumers. + +#### Framework-owned generic signature + +`RedisVersionedSession.<T>getAttribute(String)` must retain Spring Session's inherited signature. +Apply a method-only `TypeParameterUnusedInFormals` suppression with the interface-contract reason. + +#### Instance-owned retry context + +`OutboundRetryPolicy` keeps its instance `ThreadLocal`. Making it static would leak call context +between policy instances on the same thread. Add a field-only `ThreadLocalUsage` suppression and a +regression proving policy A's context is invisible to policy B and is cleared by `endCall()`. + +#### Array-bearing records + +- `NotificationCiphertext` retains its public array components because it already clones inputs and + accessors, implements content-based equality/hash code, and redacts `toString`. Add focused + defensive-copy/equality/redaction tests and an exact record-level suppression. +- The four internal session command/outcome records in `VersionedRedisSessionStore` remain internal + transport envelopes. Preserve defensive copies, document that generated record equality is not + their contract, add constructor/accessor copy tests, and suppress `ArrayRecordComponent` on each + exact record. +- The private test fake in `RedisVersionedSessionRepositoryTest` receives the same exact nested-type + treatment; no public type is changed. + +#### Mechanical behavior-neutral fixes + +- Express 72 hours as `Duration.ofDays(3)` in application/bootstrap/sample settings and matching + tests. +- Add the missing public Javadoc summary in `TracingSampleRateResolver`, and render annotation names + such as `@WebMvcTest` as inline `{@code ...}` rather than accidental block tags. +- Add missing `@Override` annotations in sample test fakes. +- Replace readability-only string concatenations with text blocks where the literal bytes remain + identical. +- Replace Boolean wrapper comparisons with boolean literals. +- For the three test-only delimiter warnings, preserve each existing grammar explicitly: retain CSV + empty-token filtering with a limit-bearing split or scanner, scan mapping-path segments without + changing leading/trailing-empty behavior, and parse the single HTTP byte-range hyphen with an + asserted `indexOf` boundary. These are not allowed to inherit the ETag scanner because their + grammars differ. + +### 3. Third-party API migration + +#### Jackson 3 + +In `LocalJsonSchemaRegistry`, replace deprecated `JsonNode.isTextual()`/`textValue()` with +`isString()`/`stringValue()`. Existing type guards remain, and JSON schema identity/reference/value +tests prove identical acceptance and rejection behavior. + +In `DeterministicEnvelopeWriter`, replace the deprecated convenience call with +`jsonFactory.createGenerator(ObjectWriteContext.empty(), output, JsonEncoding.UTF8)`, the +non-deprecated Jackson 3.0.2 overload. Preserve canonical byte output; the existing deterministic +envelope golden tests are the behavior gate. + +#### Lettuce + +Convert both finite canonical scores to `BigDecimal`, build one inclusive +`Range<? extends Number>` for each invocation, and call the typed `zcount(key, range)` and +`zrangebyscoreWithScores(key, range, Limit.create(offset, count))` overloads. Preserve inclusive +bounds, offset, count, and exact reply mapping. A dynamic-proxy regression verifies both typed +overloads are selected; sorted-set primitive contract tests verify results. + +#### AWS SDK retry + +Replace old `RetryPolicy` and core `EqualJitterBackoffStrategy` with `StandardRetryStrategy`, the +retries API half-jitter exponential backoff, `maxAttempts`, and +`ClientOverrideConfiguration.Builder.retryStrategy`. Tests assert maximum attempts and normal versus +throttling backoff configuration. The focused object-storage check must cover provider assembly; +compile-only success is insufficient. + +#### Testcontainers Toxiproxy + +Use the Testcontainers 2 toxiproxy package and a typed `ToxiproxyClient`/`Proxy` with an explicit +exposed proxy port. Fault tests must still prove cut and restore behavior against MinIO. Dependency +and lock changes stay inside the object-storage leaf. + +#### Remaining JDK/generic deprecations + +- Replace deprecated `new URL(String)` test construction with `URI.create(...).toURL()`. +- Replace the varargs `thenReturn(firstFuture, secondFuture)` stub in + `S3ConditionalObjectControlStoreTest` with two chained single-value `thenReturn(...)` calls, so + Mockito does not create the unchecked generic `CompletableFuture<PutObjectResponse>[]` array. +- Resolve every `-Xlint:deprecation,unchecked` location individually; do not suppress the source + set. + +### 4. Legacy object-storage compatibility seam + +The canonical object-storage ports and sample publication path already exist. The legacy runtime is +still selected in local/test configuration and cannot be deleted solely to silence warnings. + +Keep `@Deprecated(forRemoval = true)` on the genuinely replaced whole-byte contracts: + +- `ObjectStoragePort`; +- `StoredObject`; +- `ObjectStorageSettings`. + +Apply `removal` suppression only to exact compatibility owners: + +- `ObjectStoragePort` for its legacy receipt return type; +- `FilesystemObjectStorageAdapter` and `S3ObjectStorageAdapter`; +- `UploadPosterImageUseCase`; +- the legacy bean method in `PosterImageApiConfig`; +- `LegacyPosterImageController`; +- `PosterWebMapper.toStoredObjectResponse`; +- named legacy characterization test classes and single legacy-receipt test methods. + +The six `application.storage.migration` types and `AdoptLegacyPosterImageUseCase` are the mechanism +used to complete data adoption and currently have no replacement. Change their lifecycle marker +from `@Deprecated(forRemoval = true)` to plain `@Deprecated`; use exact `deprecation` suppression +only inside adoption implementation/configuration. Keep the application-core architecture contract +requiring `forRemoval=true` only for `ObjectStoragePort` and `StoredObject`. Keep the adapter-owned +`ObjectStorageSettings` marker and add its lifecycle assertion in the object-storage leaf. + +This keeps migration debt visible without falsely claiming that the migration mechanism itself is +ready for removal. + +### 5. Test/static-analysis/output cleanup + +#### SpotBugs + +Reuse one static `SecureRandom` in `RedisPrimitiveRuntimeServiceTest` rather than constructing a +one-shot generator. After all test reports are clean, make every ordinary and custom test-source +SpotBugs task included by `check` blocking. SpotBugs analysis errors and missing classes remain +separately fail-closed. + +#### Intentional architecture fixtures + +Keep prohibited `BigDecimal(double/float)` constructor bytecode and apply method-only +`BigDecimalLiteralDouble` suppressions. Fix unrelated warnings in allowed fixtures normally. A +suppression must never replace the forbidden operation the ArchUnit test is supposed to detect. + +#### Redis lab expected failures + +Change `assert_fails` to capture stdout/stderr per case, assert a non-zero exit and the exact expected +diagnostic, reject extra lines, and print the capture only when the assertion fails.

body 미소비, decode 오류, cancel, size 초과 후에도 pool과 buffer가 회수된다. | +| Auth | token refresh single-flight, 401 최대 1회, secret rotation이 검증된다. | +| TLS | trust-all과 hostname 검증 해제가 startup에서 차단된다. | +| SSRF | canonicalization, DNS/IP, redirect, egress 테스트가 통과한다. | +| Streaming | first byte 이후 transparent retry가 0회다. | +| Observability | logical call과 attempt가 분리되고 forbidden label이 없다. | +| Failure | DNS, pool, TLS, reset, partial response, HTTP/2 GOAWAY를 재현한다. | +| Performance | 설정된 thread, heap, direct memory, pool, retry budget 상한을 넘지 않는다. | +| Compatibility | Spring 6.2·7.0과 지원 transport matrix가

최대한 많이 열어두되, 호출자가 URL·timeout·retry·credential·TLS·resource lifecycle을 임의로 조립하게 하지 않는다. 일반 호출은 Typed Client와 Named Client Profile을 사용하고, 플랫폼은 요청이 실제로 실행됐을 가능성과 다시 실행해도 되는지를 증거 기반으로 판정한다. + +구현 우선순위는 다음으로 고정한다. + +```text +Core 계약 +→ Named Client Profile +→ Transport SPI와 Testkit +→ Deadline·Target·Observability +→ Apache·JDK Blocking +→ RestClient와 Typed Client +→ Execution Evidence와 Retry +→

Sharing the host network namespace makes the address the topology advertises the +address the client can use, which is the difference between testing the SDK and testing Docker's +network. + +That is also why their ports are fixed rather than parameterised: the addresses are written into +Sentinel's and the cluster's own configuration at creation time, and a lane whose two halves can +disagree fails for reasons that are not the SDK's. + +## Selection is by lane, not by hand + +`redisTopologyTest` derives its JUnit tag expression from the declared mode: `redis-topology & +lane-<mode>`. A promotion test is meaningless without sentinels and a cross-slot test is meaningless +without a cluster, but expressing that as a runtime assumption would turn "the lane was never +started" into a green skip. Selecting by tag keeps it fail-closed — what a mode cannot prove is not +selected, and what is selected must pass. + +The lane also fails closed on its endpoint: selecting `redisTopologyTest` without host, port, and +mode (and `redis.topology.master` on the Sentinel lane) is an error, never a skip. A topology test +that silently passes because it did not connect is worse than no topology test. + +## `min-replicas-to-write` on the Sentinel lane + +The Sentinel lane sets `min-replicas-to-write 1` and `min-replicas-max-lag 1`, and this is not +incidental configuration. Without them the lane measured a promotion in which the superseded primary +kept answering `+OK` for eleven seconds after it had been replaced: **2,086 writes acknowledged to +the caller and then discarded**, with exactly one command failing.

PATCH endpoints must distinguish *absent* (no change), + *explicit null* (clear field), and *value* (replace). Use + `org.openapitools:jackson-databind-nullable` (`JsonNullable<T>`) or + `Optional<T>` wrappers on request records. +- **B3 — Mapper-internal failures.** Map record canonical-constructor + `IllegalArgumentException`, MapStruct generated NPE, ACL normalization + failures, etc. by throwing `MappingException` (sample implementation in + `sample-portfolio`); the global handler routes it to `MAPPING_FAILED` (HTTP 400), + never to `BAD_PARAMETER` or `INTERNAL_ERROR`. Plain `IllegalArgumentException` + remains `BAD_PARAMETER` for non-mapper callers. +- **B4 — Validation layering.** Class-level Bean Validation constraints belong + to the *syntax* layer (request DTO).

Raw external response types must not leak + into `domain-core`. +- **B8 — Bulk endpoint partial success.** Envelope `success = true` only when + every item succeeded.

The deserialization switches (B1) and the +null/empty/missing 3-state (`Patch<T>` + `JsonNullable`, B2) already cover the +inbound side; the rules below cover the outbound side. The Jackson properties +live in `app-bootstrap` (`application.yml` `spring.jackson.serialization.*` / +`spring.jackson.generator.*`); ArchUnit + effective-config tests live in +`app-bootstrap` (`JacksonSerializationPolicyTest`, `no_bigdecimal_double_constructor`). + +- **S1 — Date / time / timezone (D2).** `WRITE_DATES_AS_TIMESTAMPS=false` is + pinned, so `java.time` values serialize as ISO-8601 strings via `JavaTimeModule` + (`OffsetDateTime` → `"...Z"`, `LocalDate` → `"YYYY-MM-DD"`), never a numeric + epoch or `[y,m,d,...]` array. Server timezone is **UTC**: emit instants as + `OffsetDateTime`/`Instant` with a `Z` offset. Use `LocalDate` only for + date-only calendar fields. Do **not** put timezone-less `LocalDateTime` on a + response DTO — it serializes without an offset and breaks the contract. +- **S2 — Money / BigDecimal (D3).** Default scale 2, rounding `HALF_UP` unless + the domain documents otherwise (KRW/JPY = scale 0 with a schema note). + `WRITE_BIGDECIMAL_AS_PLAIN=true` is pinned so values never serialize in + scientific notation. Pick **one** JSON representation per API and state it in + the OpenAPI schema: **string** (`@JsonSerialize(using = ToStringSerializer.class)`) + for public / financial endpoints (client parses, no precision loss), or + **number + plain** for internal service-to-service endpoints. Never rely on + the default — decide at endpoint design time. +- **S3 — `new BigDecimal(double)` is banned.** The `double`/`float` constructors + capture binary floating-point error (`new BigDecimal(0.1)` ≠ `0.1`). Build from + a `String` (`new BigDecimal("0.1")`) or `BigDecimal.valueOf(double)`. Enforced + by the `no_bigdecimal_double_constructor` ArchUnit rule (D3 / SBMS-C3). +- **S4 — Enum / null·empty·missing.** Request-side unknown enum → + `VALIDATION_FAILED` (B1 `read-unknown-enum-values-as-null=false`); legacy values + map through an explicit adapter, never a silent fallback. The + absent / explicit-null / value distinction is owned by the inbound web mapper + (Controller DTO → Command), expressed with `Patch<T>` (B2); `domain-core` and + `application-core` receive the already-resolved 3-state, never a wire type. +- **S5 — Out of this branch's scope.** OpenAPI drift enforcement (D5) is owned by + the verification suite / api-contract-baseline; removed-field-reuse ban tooling + (D6, `x-removed-fields` vs markdown catalog) is `needs-confirmation`; Avro + Schema Registry for outbox/event (D7) and response field rename/versioning + (`feature-api-compatibility-deprecation-contract`) are separate branches. + +## Business rule validation contract + +`feature-business-rule-validation-contract` (LLM Wiki branch note) fixes **which +rule is validated at which boundary**, so "validation" does not collapse into the +controller DTO or a DB constraint.

The + `validation_constraints_stay_at_web_boundary` ArchUnit rule fails the build if a + Bean Validation annotation leaks into `..domain..` or `..application..`. +- **C2 — Business invariants live in the domain, un-bypassable.** Enforce invariants + in the value-object / entity **constructor** (the sole construction path) and keep + the type immutable, so no application-service or persistence path can hand out an + invariant-violating instance. A DB constraint is a backstop, never the only check + (Forbidden: "DB constraint as only invariant"). +- **C3 / C7 / D9 — Persistence integrity maps to an operational error, leak-free.** A + unique/FK/check/serialization failure maps to `DATA_INTEGRITY` / `CONFLICT` with a + **client-safe message only**. The raw SQL, constraint/index name, SQLState code, + exception class, and stack frame must never reach `error.message` or + `error.details`. The base `GlobalExceptionHandler` catch-all already replaces the + message with `"Internal server error"` and emits `null` details; the + category-correct mapping (23505 → `CONFLICT/DB_UNIQUE_VIOLATION`, …) is owned by + `feature-persistence-failure-baseline`'s persistence-adapter translator. +- **C8 — Duplicate validation needs a canonical owner.** The same rule MAY be + pre-checked at another layer for UX / performance (e.g. an application pre-check + mirroring a DB unique constraint), but the **canonical owner** of the rule must be + named in a code comment or the relevant `CLAUDE.md`.

The SDK is a separate + concern from the semantic cache ports and must not be reached from `application-core`. + +## Redis SDK (`…cache.redis.sdk`) + +The Redis wrapper and typed API described in +`docs/superpowers/specs/2026-08-07-redis-wrapper-typed-api-design.md` lives inside this leaf. Its +design models the SDK as twelve Gradle modules; this repository's 19-leaf fail-closed registry +outranks that layout, so each designed module is a package instead. Delivery status and the full +adaptation rationale are in +`docs/superpowers/plans/2026-08-07-redis-wrapper-typed-api-status.md`. + +- `sdk.api..` is the public contract. It must never import Spring, Lettuce, Micrometer, or any SDK + implementation package; Reactor is confined to `sdk.api.reactive`. +- `sdk.lettuce..` implements the contract; `sdk.config` owns properties, the capability probe, and + the permit authority. +- `src/main/resources/redis-sdk/redis-command-policy.yml` is the command policy SSOT. A command that + is not classified there is refused, so adding a command means editing that file, not the code. +- `sdk.lettuce.operations` implements the typed operations. Everything there goes through + `RedisCommandGateway`, the only seam that reaches Lettuce, and every call is admitted by + `CommandPolicyGuard` before it runs. Never call the driver from an operation directly. +- `sdk.cluster` owns client-side slot arithmetic and cluster observation. It depends on `sdk.api` + only and must never import Lettuce: the slot is computed before a command is built, which is what + lets `CommandPolicyGuard` refuse a cross-slot request instead of learning about it from a server + redirect. +- `sdk.programmability` owns transactions, registered Lua scripts, and deployed function calls. A + script body is never accepted at call time: `EVAL` is blocked in the catalog and only `EVALSHA` of + a `RedisScriptRegistry` digest is reachable. `FUNCTION LOAD` is admin-plane, never application. +- Transactions are `WATCH`/`MULTI`/`EXEC` and **never** roll back. `TransactionResult` reports only + "executed" or "a watched key changed, so nothing ran", and no type in this package offers a word + that suggests otherwise. A queued command returns a `QueuedReply` that throws when read before the + commit, because inside the window the server has answered `+QUEUED` and nothing else. Queued + commands pass the same `CommandPolicyGuard` admission as ordinary ones — a transaction is not a + way around the guard — and the window is closed on every exit path, including a callback that + threw, because a connection abandoned in `MULTI` state silently queues the next caller's command. + The queue is write-only on purpose: a read inside the window cannot be branched on, so the reads a + transaction depends on belong before it, under `WATCH`. +- `sdk.raw` is the approved raw command gateway. A command is reachable only when the catalog marks + it `RAW_ONLY` *and* the deployment registered an `ApprovedRawCommand` for it; keys are parsed back + out of the arguments and namespace-checked before anything is sent. Never add a method here that + takes a command name as a string. +- `sdk.admin` is the read-only diagnostic plane. It takes its own gateway (admin ACL account, own + connection), refuses any command the catalog does not classify `ADMIN_ONLY` and read-only, and + projects replies so a slow log or client listing never carries arguments, peer addresses, or + connection names. +- `sdk.extensions.*` holds the Redis 8 modules (JSON, Search, Time Series, Probabilistic). Every + bean is created through `ifSupported(...)` — the capability probe decides, the catalog minimum is + only a pre-filter — and all of them build commands through `ExtensionCommandRunner` so the guard + sees their keys. Search is the exception that proves it: an index is not a key, so its name is + namespaced by `LettuceRedisSearchOperations` itself. +- `RedisSdkModuleBoundaryTest` enforces the package graph, driver containment, the absence of any + arbitrary string command surface, and the list of designed-but-unimplemented modules. Update + `NOT_YET_IMPLEMENTED_MODULES` when a module lands. +- Decisions that must not be changed without revisiting the design: no unbounded `entries`, + `members`, `rangeAll`, or `keys`; no optional R2 permit or budget; no arbitrary command string + overload; no automatic retry of a non-idempotent write after a timeout; no real key in a metric or + trace tag. + +## Boundaries + +- Allowed dependency edges come only from the module's + `src/config/architecture/modules.json` entry. +- No inbound transport, persistence entity/repository, bootstrap, or sample dependency. +- Cache adapters do not decide business freshness, entitlement, or domain fallback rules. +- Physical Redis TTL must equal encoded hard expiry; future/corrupt schema must never collapse into + an ordinary miss. +- Application/domain code must not receive raw Redis keys, commands, Lua/Function names, SDK + objects, topology, or connection types. +- Cache fail-open behavior must not be reused for session, idempotency, strict quota, lease, or + fencing. +- Rate-limit composition must not reuse `app.cache.redis`, its connection, external client mode or + failure-open semantics; v1 is coordination-role and fail-closed only. +- The standalone runtime/cache service lane is R1 evidence only. Sentinel/Cluster, TLS/ACL, + persistence/restart, eviction and fault evidence are required separately for R2. + +## Tests + +Focused tests use fakes for contract, key, catalog, and typed-facade behavior. R1/R2 promotion +requires a separate real Redis service lane; it may never be silently skipped when selected. + +`redisTopologyTest` is the only real-server lane. It is opt-in and fail-closed in seven ways: the +lane must be one of `standalone`, `sentinel`, `cluster`, `tls`; the endpoint properties must be +present (`sentinel` additionally needs `redis.topology.master`, `tls` needs +`redis.topology.trust-material`); a test class carrying the lane's tag must exist; a run that +executes zero tests fails; the classes the lane exists to run must actually have run; the executed +count must reach the lane's declared floor; and a skipped test fails the run rather than counting +as executed. `tls` is a lane, not a deployment mode — its shape is standalone and the task maps it +so, because what it qualifies is the transport. + +## Composition + +`RedisSdkAutoConfiguration` is the only place Redis settings and Redis runtime come into existence, +and it exists only while `app.redis.enabled` (env `APP_REDIS_ENABLED`) is true. It builds the +client, the connection owner and the health contributors; `RedisCapabilityConfig` in `app-bootstrap` +composes the semantic ports on top, one per role selector. "Redis is on" therefore means the +capabilities that need Redis exist, not merely that Redis is reachable. + +Every capability renders its keys under the one namespace from `app.redis.namespace` — +`{environment}:{service}:{domain}` — through `CapabilityKeyspace`. Never give a capability its own +prefix tokens: four capabilities each joining two free-form strings produced four different key +shapes, and the deployment's ACL pattern matched none of them. + +Lanes authenticate as different accounts. `RedisConnectionKind.credentialRole()` maps the lane to a +`RedisCredentialRole`, and the topology factory builds one client per *configured* role — so a +single-account deployment still gets exactly one client and one event loop. The `SCRIPT` lane is +the reason it exists: `SCRIPT LOAD` and `EVALSHA` belong to the advanced account, so the account +that reads a cache entry cannot execute a script. + +A Cluster transaction runs on one node, so `RedisTransactionRunner` derives a routing key from the +watched keys (or an explicit `RedisSlotTag`) and pins the `TRANSACTION` lane to the node that owns +that slot. Routed leases are never pooled: a pooled connection is pinned to the previous caller's +node. + +`RedisSdkSettings` +must never carry a class-level `@ConfigurationProperties`: the bootstrap's application-wide +`@ConfigurationPropertiesScan` would then register it in every deployment, so a service that runs +no Redis would bind Redis configuration. `RedisOptionalityContractTest` in `app-bootstrap` enforces +that.

CACHE 장애는 +`redisOptional`의 `state=DEGRADED` detail로만 나타나고 readiness를 내리지 않는다. +COORDINATION/SESSION 장애는 `redisRequired`를 `DOWN`으로 만들며, 어떤 Redis contributor도 +liveness에는 포함되지 않는다. role binding이 없으면 Redis client 생성과 Redis health +contributor 생성은 모두 0이다. + +이 runtime은 Redis `CONFIG GET/SET` 권한을 요구하거나 노출하지 않는다. 따라서 +`expected-eviction` 검증은 설정 의도에 대한 startup 검증이며 실제 server의 +`maxmemory-policy`를 증명하지 않는다. Snapshot/health detail은 이 한계를 +`CONFIGURED_EXPECTATION_ONLY`로, 외부 증거 상태를 +`externalEvictionAttestation=INCOMPLETE`로 명시한다. 운영 readiness를 더 강하게 만들려면 배포 +파이프라인의 외부 conformance job 또는 서명된 operator attestation으로 effective policy를 +검증해야 한다. semantic probe는 runtime `CONFIG`/`ACL` 조회나 변경 권한을 요구하지 않는다. + +## Distributed edge rate limit + +`shared-contract`의 `EdgeRateLimitPort` 뒤에서 fixed window, sliding-window counter, token bucket을 +정확히 하나의 versioned Lua 실행으로 평가한다. 세 프로그램은 Redis `TIME`을 한 번만 읽고, server +time, bounded clock-regression clamp, denial-no-consume, finite state TTL과 정확히 7개 필드인 응답 +계약을 공유한다. Redis `TYPE`의 status-table/string 차이를 정규화하고 malformed hash field는 +typed incompatibility로 닫는다. Token bucket은 refill division remainder를 상태로 보존해 호출 +빈도에 따라 quota가 달라지지 않는다. Sliding counter만 algorithm certainty가 approximate이고 +나머지는 certain이다. + +모든 closed program manifest의 `minimumRedisVersion`은 실제 minimum qualification lane과 같은 +7.2다. 더 낮은 Redis 버전은 별도 service lane이 추가되기 전까지 호환을 주장하지 않는다. + +## Redis-backed HTTP session + +`redis-session` readiness card는 standalone을 선택 topology로 하는 implemented candidate다. +`RedisVersionedSessionRepository`는 Spring Session의 저장소 경계만 구현하고, 쿠키·CSRF·session +fixation 정책은 inbound web이 소유한다. 실제 Redis 상태 변경은 manifest로 닫힌 6개 Lua 프로그램 +(create/inspect/save/touch/revoke/rotate)을 통해서만 수행한다. + +- raw session ID는 physical key에 들어가지 않고 versioned HMAC digest로 변환된다. +- idle timeout과 absolute lifetime을 동시에 적용하며 touch 쓰기는 설정된 interval로 제한한다. +- logout은 revision `0`의 adapter-private force-revoke를 사용한다. 하나의 Lua 실행에서 tombstone을 + 먼저 만들고 live hash를 삭제하므로 concurrent stale save가 세션을 부활시킬 수 없다. +- rotation은 old ID tombstone과 new ID 생성을 원자적으로 수행한다. old/new ID가 서로 다른 Cluster + slot이므로 현재 activation은 standalone만 허용하고 Cluster와 Sentinel을 startup에서 거부한다. +- 저장 payload는 N/N-1 version을 읽는 명시적 primitive allowlist envelope다. Java serialization과 + default typing을 쓰지 않는다. SHA-256 checksum은 우발적 손상 탐지용이며 authenticity 또는 공격자 + 변조 방지 보장이 아니다. +- timeout/response loss와 OOM은 성공이나 miss로 바꾸지 않고 unavailable/indeterminate로 닫는다. + 별도 요청에서 같은 operation ID를 자동 재사용해 reconcile하지 않으므로 운영자는 timeout 뒤에 + mutation 성공을 추정하면 안 된다. + +현재 저장소는 의도적으로 unindexed baseline이다. principal lookup, 사용자 전체 logout, +maximum-concurrent-session 제어는 제공하지 않는다. 이 기능이 필요한 프로젝트는 별도 bounded index와 +그 index의 원자성·복구 증거를 추가해야 한다. 현재 `card-redis-session` 레인은 같은 JVM 안의 서로 +독립적인 두 runtime/repository client가 하나의 standalone Redis를 공유할 때의 logout/stale-save +race, TLS+named ACL, partition+`noeviction` OOM/recovery, Redis 7.2/7.4 compatibility를 검증한다. +이는 multi-process/pod, rolling deployment, pod/network failure qualification이 아니다. + +아웃바운드 provider의 기본값은 +`ca-skeleton.capabilities.rate-limit.provider=disabled`다. `redis`로 선택하면 canonical +`COORDINATION` role, `failure-policy=fail-closed`, default policy와 secret reference가 모두 +필요하다. `app.rate-limit.enabled`는 HTTP transport enforcement만 제어하며 provider를 암묵적으로 +선택하거나 fallback을 만들지 않는다. 설정은 `app.cache.redis`를 fallback으로 사용하지 않고, +`distributedRateLimiter`라는 semantic port bean만 외부에 제공한다. Caller deadline이 canonical +Redis command timeout보다 짧으면 command를 보내지 않고 typed no-mutation outcome을 반환한다. + +Rate-limit physical key는 raw principal/IP/API key를 포함하지 않고 policy ID/revision/algorithm과 +이미 pseudonymized된 subject digest를 다시 HMAC한다. Unknown policy/state/program/reply, +pre-send admission failure, post-dispatch indeterminate failure와 unsafe Redis clock을 서로 다른 +outcome으로 보존하며 fail-open하지 않는다. 현재 standalone과 standalone TLS+named ACL의 +`implemented-candidate` evidence가 있다. Sentinel/Cluster, topology failover, +credential/certificate rotation, effective eviction/persistence attestation과 R3 증거는 없으며, +checked-in `selected` card가 없으므로 R2 release claim도 없다. + +## Application cache contract + +`application-core`의 `CacheRegionPort<K,V>`는 다음을 분리한다. + +- fresh/stale positive hit; +- authoritative negative hit; +- normal absent/expired/invalidated miss; +- incompatible schema; +- unavailable/overloaded와 operation certainty; +- recorded/conditional/degraded/indeterminate mutation; +- invalidated/already-absent/degraded/indeterminate invalidation. + +TTL, jitter, codec, topology와 Redis SDK 타입은 이 port에 들어가지 않는다. 실제 product의 +use case는 `CacheRegionPort`를 상속한 semantic subtype을 정의해야 한다. + +`application-core`의 `CacheAsideExecutor`는 lookup/source/write 흐름을 공통화하고 다음을 +보장한다. + +- fresh/negative hit에서 source를 호출하지 않음; +- authoritative absence만 negative cache하고, miss refill은 `ONLY_IF_ABSENT`, stale/quarantine + refill은 `ONLY_IF_OBSERVED`로 기록; +- classified transient source failure에서만 hard expiry 전 stale fallback; +- local single-flight의 in-flight key/waiter bound와 abandoned-flight opportunistic cleanup; +- source bulkhead의 concurrency/admission/load deadline bound; +- unclassified exception과 interrupt/cancellation 보존. + +동기 source loader는 cooperative cancellation token을 확인해야 한다. 임의 source 코드를 +강제 종료하지 않으며, source가 token/deadline을 무시하면 bulkhead permit은 반환 시점까지 +점유된다. + +## Physical key + +`RedisKeyBuilder`만 다음 canonical shape를 만든다. + +```text +ca:<app>:<env>:<capability>:<region>:hv<hashVersion>:kv<keyVersion>:{<slot>}:<digest>:<kind> +``` + +민감한 사용자/tenant/composite 값은 raw key에 넣지 않는다. length-prefixed canonical bytes를 +HMAC-SHA-256으로 digest한다. random opaque identifier는 SHA-256을 사용할 수 있다. builder는 slug, +version, 정확히 하나인 hash tag와 전체 UTF-8 byte bound를 검증한다. + +## Atomic program foundation + +`redis/*-program-set.json`과 `redis/program-set.json`은 cache/rate/idempotency/lease/session 및 +primitive Lua resource의 exact digest, signature, status, complexity와 timeout certainty를 +기록한다. `RedisAtomicPrimitives`는 compare-delete, +compare-expire, set-if-absent-with-TTL, replace-if-observed-with-TTL을 typed result로 노출하고 +unknown status를 compatibility failure로 처리한다. owner/value/observation/operation/TTL은 +Redis 호출 전에 제한된다. `redis/rate-program-set.json`은 structured rate-limit 프로그램의 +별도 digest/signature/status manifest다. +Generic descriptor/catalog/executor와 typed primitive facade는 package-private collaborator다. +Spring composition에는 raw Redis key/value/TTL을 받는 bean을 노출하지 않으며, 이후 semantic +port adapter가 내부에서만 이 facade를 사용한다. +이 primitive facade 자체는 application에 노출되는 범용 Redis port가 아니다. Cache, rate limit, +idempotency, soft lease, session의 semantic provider만 closed catalog를 내부에서 소비하며, 이 +구조 자체가 release selection이나 R2 qualification을 뜻하지 않는다. + +`RedisLuaProgramExecutor`가 catalog source로 SHA-1 script identity를 계산하여 `EVALSHA`를 먼저 +호출하고 정확히 `NOSCRIPT`일 때만 catalog script를 `SCRIPT LOAD`한다. 반환 digest가 예상 identity와 +같은지 확인한 뒤 `EVALSHA`를 한 번만 재시도한다. signature/argument bounds는 +client 호출 전에 다시 검증하고 descriptor catalog membership 및 반환 status membership을 +확인한다. unit lane은 강제 `NOSCRIPT` load/retry를 검증하고 standalone real-service lane은 +compare-and-delete, NX, bounded trailing-digest observed replace, concurrent-writer 보존을 실제 +Redis 7.2에서 검증한다. 같은 lane은 16MiB payload의 record/read/observed-replace와 +16MiB+1 사전 거부, mutation interrupt의 `INDETERMINATE` certainty와 interrupt flag 복원도 +실행한다. + +## Managed runtime과 semantic region + +Canonical activation은 +`ca-skeleton.capabilities.cache.bindings.default=redis`와 +`ca-skeleton.providers.redis.roles.cache`를 함께 요구한다. 전자는 semantic policy를, 후자는 +topology/TLS/ACL credential을 소유한다. Canonical region은 legacy `app.cache.redis.host`, +`password`, raw HMAC 값을 읽지 않고 CACHE role router와 +`RedisCredentialMaterialProvider`의 `secret://` reference만 사용한다. 같은 CACHE router가 L2 +command와 invalidation Pub/Sub을 함께 route하므로 topology rotation 때 새 subscription ACK가 +확인된 뒤 route가 교체된다. Canonical/legacy 동시 활성은 precedence를 추측하지 않고 startup에서 +거절한다. 현재 템플릿이 자동 조합하는 semantic region ID는 `default` 하나이며, 여러 product +region은 region registry/compiler가 추가되기 전까지 자동 생성한다고 주장하지 않는다. + +`app.cache.redis.enabled=true`이고 `client-mode=managed`(기본값)이면 `LettuceRedisRuntime`이 +단일 binary connection을 생성하고 종료 시 connection/client를 닫는다. 프로젝트가 +`RedisClient`를 직접 제공하는 경우에는 `client-mode=external`을 명시해야 한다. 이 선택을 +명시함으로써 Spring configuration 처리 순서에 따라 managed/custom client 선택이 달라지지 않는다. +Managed runtime은 reconnect 시 pending command를 replay하지 않고, disconnected command를 +pre-send 거부하며, request queue와 동시 outstanding command를 같은 finite bound로 제한한다. +`RedisStringCacheRegion`은 `CacheRegionPort<String,String>` bean으로 제공되며 다음 결과를 +구분한다. + +- positive hit, authoritative negative hit, normal miss; +- unknown/corrupt/retired envelope와 fail-fast future envelope; +- read unavailable/overloaded와 mutation not-applied/indeterminate; +- invalidated와 already absent. + +opaque source revision에는 대소 비교 의미가 없으므로 +`ONLY_IF_SOURCE_REVISION_NEWER`는 임의 lexical comparison을 하지 않고 +`NOT_RECORDED_PROVIDER_POLICY`를 반환한다. + +Envelope v2는 source revision, soft/hard absolute expiry와 payload를 digest로 보호한다. +`soft <= now < hard`는 stale, `hard <= now`는 expired miss다. Retired v1은 명시적 quarantine +후 reload 대상이고 future/corrupt envelope는 fail-fast다. Integrity digest를 version byte보다 +먼저 검사하며, digest가 맞더라도 현재 v2 구조가 잘못되면 corrupt로 분류한다. Stale/retired +lookup은 envelope digest를 opaque observation token으로 전달하고, cache-aside는 Lua에서 현재 +digest가 그 token과 같을 때만 새 envelope로 교체한다. 따라서 조회와 refresh 사이의 writer를 +삭제하거나 덮어쓰지 않는다. Source revision의 application invariant (1..128 characters)는 +decode 때도 다시 검사한다. + +`positive-soft-ttl`, 기존 `positive-ttl`(hard), `negative-ttl`, `ttl-jitter`, +`minimum-hard-ttl`은 startup에 immutable policy로 freeze된다. Jitter는 HMAC-derived physical +key와 policy revision으로 결정적이며 positive soft/hard에는 같은 factor를 적용한다. Redis +physical TTL은 envelope에 기록된 hard expiry와 같다. + +추가 runtime setting은 `app.cache.redis.maximum-queued-commands=8`(범위 `1..4096`)과 +`app.cache.redis.maximum-in-flight-bytes=16777216`이다. 최대 readable envelope와 최대 command +byte를 별도로 계산하며, command count와 retained request/response byte budget을 모두 통과해야 +Lettuce 호출을 시작한다. `queue-count × maximum-command-bytes`도 byte bound 이하여야 한다. 이 관계는 +timeout 완료 뒤 driver가 응답 decode 전까지 command args를 유지하는 경우도 유한하게 제한한다. +timeout 직후에는 runtime admission population과 Lettuce retained population이 겹칠 수 있으므로 +최악 상한은 대략 `maximum-in-flight-bytes + queue-count × per-command-bound`이고, 설정 검증은 +두 번째 항이 첫 번째 항을 넘지 않게 해 최대 약 2배 population으로 제한한다. + +read는 raw `GET`을 사용하지 않는다. 고정 Lua read가 `GETRANGE(0, maximum-envelope-bytes)`로 +Redis가 wire에 내보내는 bulk reply 자체를 `maximum-envelope-bytes + 1` 이하로 자르고, 초과하면 +작은 오류 응답으로 바꾼다. 따라서 다른 writer가 같은 물리 키를 오염시켜도 전체 대용량 value를 +Netty/codec에 먼저 할당하지 않는다. managed runtime을 활성화할 때 host가 누락되면 +`localhost`로 암묵 fallback하지 않고 startup을 실패시킨다. + +Generation/revision fence는 mass/per-key invalidation과 source-load race를 막는다. Distributed +refresh soft lease는 정상 시 중복 refresh를 줄이지만 TTL expiry/crash에서는 duplicate owner를 +허용하며, cache generation fence를 대체하는 correctness lock이 아니다. + +`app.cache.redis.l1.enabled=true`는 semantic string cache 앞에만 optional local L1을 붙인다. +L1은 maximum entries, maximum accounted weight, per-entry accounted weight, local TTL, generation +recheck interval과 invalidation subscriber queue를 모두 finite하게 검증한다. Local expiry는 Redis +envelope hard expiry보다 길어질 수 없다. Weight는 HMAC-derived local identity와 UTF-8 value, +entry/lookup metadata에 대한 고정 conservative allowance를 더한 admission/eviction accounting +proxy이며, JVM heap reservation이나 실제 object layout의 exact byte guarantee가 아니다. + +Invalidation Pub/Sub payload는 raw semantic key를 포함하지 않고 HMAC-authenticated bounded +message를 사용한다. Pub/Sub은 durable/exact invalidation 원장이 아니라 eviction hint다. Subscriber +disconnect나 queue overflow는 L1 전체를 flush하고, monotonic local invalidation epoch가 진행 중인 +generation probe와 refill admission을 무효화한다. 재연결 뒤 generation을 다시 읽기 전에는 L1 +admission을 허용하지 않는다. Hint 유실 시 mass invalidation은 periodic generation recheck, +per-key invalidation은 local TTL 안에서 Redis L2로 복귀한다. + +이 local tier는 cache-only internal type을 요구하므로 session, idempotency, strict rate-limit, +coordination provider에 적용할 수 없다. 해당 capability들은 local fail-open cache semantics를 +재사용하지 않는다. + +Refresh-ahead와 probabilistic early refresh는 아직 구현하지 않았다. 둘 다 correctness baseline이 +아니며, refresh-ahead는 명시적인 bounded hot-set registry/scheduler 없이 full keyspace scan으로 +대체하지 않는다. Probabilistic early refresh도 versioned probability descriptor와 deterministic +property test가 생기기 전에는 readiness guarantee로 광고하지 않는다. Cache card에는 standalone +TLS+named ACL과 bounded fault evidence가 있지만 Sentinel/Cluster Pub/Sub/failover, +credential/certificate rotation, persistence/restart, effective eviction attestation, +multi-process/pod L1/L2 coherence와 R3 qualification은 아직 없다. + +## Efficiency-only lease + +`ca-skeleton.capabilities.lease.provider=redis`를 명시한 경우에만 +`DistributedLeasePort`가 생성되며, canonical `COORDINATION` role router와 별도 HMAC secret +reference를 사용한다. 미선택 상태에서는 lease bean, secret resolution, native client와 thread +side effect가 모두 0이다. + +이 port의 guarantee는 오직 `EFFICIENCY_ONLY`다. acquire/inspect/renew/release는 같은 +owner token과 operation ID를 비교하고, response loss를 성공이나 실패로 추측하지 않고 +`INDETERMINATE`/`UNKNOWN`으로 유지한다. caller가 최초 send 전에 보관한 같은 attempt로 inspect +또는 acquire replay를 해야 ownership을 복구할 수 있다. Handle validity는 Redis가 보고한 remaining +TTL에서 command 왕복 monotonic elapsed와 drift budget을 차감하며, server expiry wall clock은 +telemetry 용도일 뿐이다. Watchdog는 worker와 registration 수, renewal cadence, application +deadline이 모두 유한하고 lease loss/unknown에서 작업 취소 callback을 한 번만 전달한다. + +`redisEfficiencyLeaseTest`는 pinned Redis 7.2와 다음/승인 버전에서 standalone concurrency, +TLS/ACL, partition/response uncertainty와 compatibility를 별도 qualification한다. 이 test는 +readiness card가 아니며 cache-refresh soft lease나 fenced coordination의 증거로 재사용되지 +않는다. Fencing token과 protected-resource stale-token rejection은 구현하지 않았으므로 +`redis-fenced-coordination` card는 계속 `not-implemented`다. 이 lease만으로 결제, 재고, +unique ID 또는 외부 장치 command 같은 correctness-sensitive write를 승인하면 안 된다. + +## Legacy path + +기존 `CacheStoreRouter`, `RedisCacheStore`, `FailOpenCacheStore`는 호환성을 위해 남아 있다. 이 +경로는 `Optional.empty()`로 miss와 backend failure를 합친다. managed runtime을 사용할 때 +legacy `put`에도 positive TTL을 적용하지만, 사용자 제공 legacy client의 TTL은 보장할 수 없으므로 +새 semantic cache port 구현의 기준으로 사용하지 않는다. + +## Verification + +이 leaf가 실제로 가진 task는 `test`, `check`, `redisTopologyTest` 세 개다. + +```bash +cd src +./gradlew :adapter:outbound:cache-redis:test --console=plain +./gradlew :application-core:check :adapter:outbound:cache-redis:check --console=plain +``` + +Topology lane은 opt-in이며 fail-closed다. mode는 `standalone`, `sentinel`, `cluster`만 허용하고, +알 수 없는 mode·endpoint 누락·해당 lane tag를 가진 test class 부재·실행 test 0건은 모두 실패다. +(이전에는 오타 mode가 tag를 아무것도 매칭하지 못해 test 0건으로 `BUILD SUCCESSFUL`이 났다.) + +```bash +./gradlew :adapter:outbound:cache-redis:redisTopologyTest \ + -Predis.topology.host=127.0.0.1 -Predis.topology.port=6379 \ + -Predis.topology.mode=standalone --console=plain +# sentinel lane은 -Predis.topology.master=<master-name> 을 추가로 요구한다. +``` diff --git a/src/adapter/outbound/cache-redis/build.gradle b/src/adapter/outbound/cache-redis/build.gradle new file mode 100644 index 0000000..3086edc --- /dev/null +++ b/src/adapter/outbound/cache-redis/build.gradle @@ -0,0 +1,202 @@ +// Redis SDK leaf — see docs/superpowers/specs/2026-08-07-redis-wrapper-typed-api-design.md. +// +// The design models the SDK as separate Gradle modules.

Inside this leaf, `RoutingFilePublicationAdapter` performs an exact destination lookup +before producer invocation. The canonical operation/manifest/reference records and the provider +boundary are shared control-plane concepts; the only implemented R2 persistence/publication +provider is currently `local-persistent`. + +`local-persistent` is an explicit, fail-closed provider for a pre-provisioned absolute filesystem +root. Startup compiles destination policy, rejects implicit/default providers and shared-root +double ownership, attests owner/mode/FileStore/mount-sentinel/path identity, requires +`SecureDirectoryStream`, and probes exclusive create, hard-link publication, and file/directory +force. One provider/control/payload runtime is shared by every destination that names the same +provider ID. + +An accepted publication streams typed rows once, applies CSV/schema/formula/size policy, writes and +forces a private stage, and advances the forced control plane through: + +```text +WRITING -> SEALED -> DATA_PUBLISHED -> MANIFEST_PUBLISHED + -> REFERENCE_PUBLISHED -> PUBLISHED +``` + +Data is published with an exclusive no-overwrite hard link.

Terminal mismatches preserve all evidence.

The producer writes rows to a bounded sink and +can call `checkpoint()` for cooperative interruption checks. + +`FileExportPort.exportCsv(...)` remains for compatibility only.

`OutboxMessagePublishPort` 를 +쓴다. `OutboxMessagePublishAdapter`는 envelope mapping + broker send만 수행하며 runtime 예외를 +그대로 전파하고 checked 예외는 cause를 보존해 감싼다. 성공 DEBUG나 실패 WARN을 남기지 않는다. +반환 타입을 void 로 둬 broker SDK 타입이 어댑터 밖으로 새지 않는다(B7). + +## Legacy R0 characterization + +현재 `KafkaSender.send(...)`와 `MessageBroker.send(...)`의 정상 void 반환은 호출이 예외 없이 +끝났다는 뜻일 뿐 broker acknowledgement 증거가 아니다. relay는 이 정상 반환 뒤 legacy +`PUBLISHED`를 기록한다. sender 예외는 fail-closed outbox 경로에서 전파되어 relay의 +`FAILED/DEAD` 전이를 유발한다. + +broker 설정이 blank면 두 포트는 각각 `DisabledMessagePublisher`와 +`DisabledOutboxMessagePublisher`에

`aggregate_id`, +`correlation_id`, `attempt_count`, `runbook_link`다. retry report만 `next_attempt_at`을 추가한다. +payload/idempotency key/envelope/exception-derived field는 받거나 렌더링하지 않고 cause만 throwable로 +붙인다. logging 내부 `RuntimeException`은 adapter와 use case 양쪽에서 방어하므로 persisted +FAILED/DEAD outcome을 바꾸지 않는다. + +## Closed local binding compiler R1 + +`contract`, `destination`, `config` package는 명시적으로

adapter composition이 정확한 compiled identity를 확인해야 할 때만 public static +bridge를 사용하며, instance accessor는 package-private이고 외부에 필요한 상태는 boolean/String/ +core value로만 제공한다. 이는 broker SDK뿐 아니라 adapter 자체의 조립 타입도 B7 반환 경계를 +통해 application consumer로 새지 않게 한다. + +`MessagingCapabilityCardRegistry`는 first R2 tuple의 11개 ID와 각 role을 닫힌 Java vocabulary로 +제공할 뿐이다. readiness registry의 `not-implemented` 상태를 승격하거나

scalar/enum, +`Optional<T>`/`List<T>`/exact final nested record로만 재귀 고정하며 `Object`, interface, raw/wildcard, +generic record와 runtime record discovery를 거부한다. writer는 이 compiled graph를 따라서 각 +record accessor를 정확히 한 번 읽은 immutable snapshot을 만들고 payload를 정확히 한 번 encode한다. +schema validation에 건넨 바로 그 payload bytes를 raw JSON API 없이 envelope suffix에 삽입한다. +depth, string character/UTF-8 byte, array, object, number, payload/envelope byte limit는 writer와 +parser 양쪽에서 적용한다. output byte limit는 generator가 쓰는 bounded stream에서 allocation 전에 +강제하고, list는 size를 먼저 검사한 뒤 bounded iterator로 한 번만 snapshot한다. mutation/concurrent +access와 극단적 `BigDecimal` scale도 큰 배열/String 생성 전에 fail-closed 한다. duplicate key, +malformed UTF-8, trailing data, unpaired surrogate와 non-finite number는 replacement나 coercion +없이 거부한다. + +`LocalJsonSchemaRegistry`는 호출자가 명시적으로 제공한 exact bytes와 SHA-256만 startup에서 +Draft 2020-12 meta-schema로 검사하고 precompile한다. root `$id`와 absolute `$ref`는 lowercase +exact `urn` scheme만 허용하고 `$ref`는 동일 문서 fragment 또는 제공된 exact URN map으로 닫힌다. +HTTP/HTTPS/file/classpath/resource/jar 및 unknown absolute scheme fetch와 YAML loader는 제공하지 +않는다. public validation boundary도 UTF-8 bytes만 받는다. format assertion은 활성이다. 이 Task 6 +closed subset은 scope 추적의 모호성을 제거하기 위해 root 외 nested `$id`를 value type과 무관하게 +거부하고, `$dynamicRef`, `$dynamicAnchor`, deprecated `$recursiveRef`/`$recursiveAnchor`, `$anchor` +키워드를 어느 위치에서도 지원하지 않는다. + +Draft 2020-12 authority는 `draft/2020-12/schema` 1개와 `meta/*` 8개의 exact checked-in bytes 및 +digest로 pin한다. registry startup은 9개 digest, 각 `$id`, NetworkNT runtime schema tree를 +대조하고 하나라도 다르면 fail-closed 한다. Spring Boot executable/fat/nested JAR 배치를 깨뜨리는 +`CodeSource` regular-file/JAR 가정은 하지 않는다.

basis 가 없고 production 빈도도 미측정이다. +S3 호환 클라이언트가 템플릿에 없으므로 어댑터는 이 포트를 optional 로 취급한다 — 빈이 없으면 inline +DB 저장으로 fallback. 실제 구현(S3 / GCS / MinIO)을 와이어링하면 offload 가 활성화된다. + +## outbox — `OutboxStoreAdapter` 외 + +스키마는 Flyway(`V3__outbox_event.sql`)가 소유한다. + +### 트랜잭션 경계 계약 +- **append**: 호출자의 `TransactionPort.inWrite()` 경계 안에서 호출되어야 하며, 내부에서 새 + 트랜잭션을 열지 않는다. `@Repository` 가 빈만 등록하고

SPI (`OutboxClaimRepository`) +row claim 은 vendor 별 락 전략이 필요해 `OutboxClaimRepository` SPI 로 추출했다. canonical +PostgreSQL 구현은 native query 의 `FOR UPDATE SKIP LOCKED` 를 쓰고, 다른 벤더는 등가물을 +공급한다(예: SQL Server `WITH (UPDLOCK, READPAST)`). eligibility predicate(I3 — concurrent-relay +안전을 위한 `SKIP LOCKED`)와 per-aggregate FIFO gate(I4 — `NOT EXISTS` correlated subquery)를 +전부 SQL 에서 강제한다. 한 배치에 aggregate 당 최대 한 row(head)만 나타난다. 어댑터는 추가 +in-memory 필터링을 하지 않는다 — 리포지토리가 반환한 모든 row 를 IN_FLIGHT 로 전이시켜 호출자에 +돌려준다. 전체 SQL gate 동작은 PG contract 테스트(Testcontainers)가 검증한다. + +eligible row(I3/I4/I6): +- `PENDING` — `next_attempt_at <= now`(insert 시 즉시 eligible) +- `FAILED` — `next_attempt_at <= now`(backoff 경과) +- `IN_FLIGHT` — `next_attempt_at <= now`(orphaned row) + +### `markPublished` / `markFailed` / `markDead` 는 왜 row 부재 시 throw 하나 +row 가 없으면 `IllegalStateException` 을 던진다. relay 가 방금 같은 서비스 인스턴스에서 claim 한 +row 이므로, 부재는 프로그래밍/동시성 버그다. 조용히 no-op 하면 row 가 영원히 `IN_FLIGHT` 로 남아 +그 aggregate 의 FIFO 큐를 막고, 호출자나 로그에 아무 신호도 남지 않는다(markFailed 는 relay 가 +재시도 예약을 믿게, markDead 는 runbook 가시성·수동 DEAD 해결을 막게 된다). + +### `OutboxEventEntity` 의 결정 +- **`AuditableEntity` 미상속(D6 — infra 엔티티).** `IdempotencyRecordEntity` 처럼 outbox row 는 + 도메인 애그리거트가 아니라 인프라 record 다. 자체 temporal 필드(`occurred_at`, + `next_attempt_at`)가 도메인 의미를 갖고, generic `created_at`/`updated_at` audit 컬럼과 섞이면 + 안 된다. +- **mutating setter 노출은 의도.** relay 어댑터가 managed 엔티티 위에서 상태(status / + attempt_count / next_attempt_at)를 전이시키되 full reload-and-replace 없이 한다. outbox 어댑터만 + 이 필드를 건드리고, 모든 mutation 이 use case 소유 `TransactionPort.inWrite()` 경계 안에서 + 돌기에 안전하다. +- **`next_attempt_at` dual-purpose(I6 — 추가 컬럼 없음):** + - `PENDING`: insert 때 `occurred_at` 으로 세팅 → 최초 claim 체크(`next_attempt_at <= now`)가 + 즉시 만족. + - `IN_FLIGHT`: `claim_time + in_flight_timeout` → orphaned row 가 visibility window 만료 후 + 재claim 가능. + - `FAILED`: `now + backoff` → backoff window 경과 후에만 재시도. +- `status` 는 `PENDING | IN_FLIGHT | PUBLISHED | FAILED | DEAD` 문자열이다. + +### metric 쿼리 반환 형태 +`OutboxEventJpaRepository.countGroupedByStatus()` 는 `[status(String), count(Long)]`, +`findOldestUnpublishedOccurredAtByEventType()` 는 `[eventType(String), oldestOccurredAt(Instant)]` +2-요소 배열 리스트를 돌려준다(각각 outbox.pending.size, outbox.publisher.lag gauge 용). +`OutboxStoreAdapter.oldestUnpublishedAgeSecondsByEventType` 가 `HashMap` 을 쓰는 건 키가 +enum 이 아니라 String(event-type 이름)이기 때문이다 — `countByStatus()` 는 키가 +`OutboxEventStatus` enum 이라 `EnumMap` 을 쓴다(두 반환 타입이 의도적으로 다름). + +### `OutboxReaper` +PUBLISHED row 는 이미 전달된 terminal-success record 라 무한 보관할 필요가 없다. reaper 가 +retention 보다 오래된 PUBLISHED row 를 주기적으로 비워 테이블 성장과 metric gauge 를 묶는다. +스케줄링은 컴포지션 루트의 `@EnableScheduling` 으로 켜지고, `@Transactional` bulk delete 가 purge +를 한 문장으로 유지한다. 고정 interval / clock-skew 미처리는 프로젝트 선택(부하 하 +cadence 측정 필요). retention 한 값은 reaper-local 이라 `@Value` 로 받지만, canonical 6-property +문서는 app-bootstrap `OutboxSettings` / `application.yml` 에 있다. + +## JPA production capability candidate + +`src/config/jpa/readiness-cards.yaml`이 15개 capability와 7개 독립 schema stream의 +machine-readable SSOT다. `selected` base card와 `implemented-candidate` reliability card를

값이 *없으면* Spring Boot 기본(이 스켈레톤은 `application.yml`에서 OSIV off + 가 기본)에 맡기며 *있는 `true`*만 거부한다. + +### JpaSchemaSafetyValidator +- **Flyway를 production physical schema의 유일한 writer로 유지한다.** `prod` profile에서는 + `spring.jpa.hibernate.ddl-auto`가 `none` 또는 `validate`일 때만 허용한다. `update`, `create`, + `create-drop` 또는 그 밖의 값이면 `APP_DATASOURCE_DDL_AUTO`를 이름으로 포함한 + `PROFILE_MISMATCH`로 부팅을 중단한다. +- **local 개발 편의와 production 권위를 분리한다.** non-prod profile의 `update`/`create`는 이 + validator가 막지 않는다. prod profile 비교와 mode 비교는 대소문자를 무시해 `PROD`/`UPDATE` + 같은 변형도 guard를 우회하지 못한다. + +### RuntimeNumericBoundsValidator +- **고위험 숫자 노브(pool/thread 사이징)만 일부러 좁게 검증한다.** pool/connector 사이징 키는 + Spring-native property(`spring.datasource.hikari.*`, `server.tomcat.*`)로 직결되고 `env-keys.yaml`이 + 각각을 `positive_int` / `non_negative_int`로 표시하지만, 이 표시는 그동안 강제되지 않았다 — + Hikari/Tomcat 이 결국 거부하더라도 난해한 메시지로 init 시점에야 거부했다. 이 검증기는 resolved + Spring property 를 읽어, 운영자가 실제 설정한 `APP_*` 키를 담은 메시지로 일찍 부팅을 실패시킨다. + 잘못 설정하면 실제 런타임 장애로 이어지는 키(pool/thread 사이징)에만 범위를 한정했고, Logback + 소유 로그 사이징·Spring `Duration` 키는 (해당 라이브러리가 검증하므로) 범위 밖이다. +- **읽기 전용으로 Spring 바인딩을 중복하지 않고, 부재 키는 skip 한다.** 값이 없으면 placeholder/ + 프레임워크 기본값이 소유하므로 건너뛰고, 범위를 벗어난 *있는* 값만 거부한다("lenient default + 금지"). + +### StartupSafetyValidator +- **`SmartInitializingSingleton` 타이밍을 고른 이유가 핵심이다.** 검사는 모든 싱글톤 생성 후 context + refresh 완료 전에 한 번 돈다. `EnvironmentPostProcessor`는 bean 정의가 생기기 전에 실행돼 bean + *존재 여부*(multi-instance 검사에 필요)를 검사할 수 없고, `ApplicationReadyEvent` 리스너는 트래픽 + 직전에야 발동해 잘못된 부팅을 거부하기엔 너무 늦다. 그래서 이 중간 타이밍을 택했고, 위반 시 + throw 하여 context 가 시작을 거부한다. +- **prod 안전 토글은 잘못 켜져 있으면 PROFILE_MISMATCH(exit 71)로 죽인다.** prod 프로파일에서 내부 + 상세 노출/요청 본문 캡처 토글이 켜져 있으면 구조화된 startup-failure 로그와 함께 부팅을 중단한다. +- **multi-instance 가 켜지면 조율 bean 이 모두 존재해야 한다.** `APP_MULTI_INSTANCE_ENABLED=true`일 + 때 `REQUIRED_MULTI_INSTANCE_BEANS`(distributed lock / cache stampede protection / outbox leader + election / distributed rate limiter / migration startup job)가 하나라도 빠지면 + REQUIRED_ADAPTER_DISABLED(exit 72)로 실패시킨다. 이 bean 들은 각각 다른 브랜치가 소유하고, 이 + 검증기는 존재 여부만 단언한다. +- **prod 판정은 대소문자 무시다.** `SPRING_PROFILES_ACTIVE=PROD` 오타도 prod-safety 가드를 + 발동시켜야 하므로 `equalsIgnoreCase`로 비교한다. + +--- + +## concurrency — 도메인 컨텍스트 전파 전략 조립 + +### DomainContextConfig +- **`DomainContextPropagator`를 빈으로 노출하고, 설정에서 고른 `DomainContextStrategy`로 + `DomainContextPropagatorFactory`를 통해 조립한다.** `application-core`는 설정을 직접 읽지 않는다는 + 원칙 때문에, 전략 해석과 propagator 생성은 composition root(여기)에서 끝내고 완성된 propagator 만 + 주입한다. 그래서 use case 코드는 어떤 전파 전략을 쓰는지 몰라도 되고, 전략 교체는 코드가 아니라 + 설정으로만 일어난다. + +### DomainContextSettings +- **`ca-skeleton.domain-context.strategy`가 비어 있으면 `THREAD_LOCAL`로 기본값을 채운다.** 스켈레톤은 + "설정 없이도 바로 동작하는 기본값"을 제공하는 것을 원칙으로 하므로, 전략을 강제로 지정하게 만들지 + 않고 가장 안전한 `THREAD_LOCAL`을 디폴트로 둔다. 이 전략은 rate-limit 알고리즘처럼 전용 환경변수 + 를 두지 않는데, 보안 비밀이나 배포별 값이 아니라 운영상의 선택지라 설정 바인딩만으로 충분하기 + 때문이다. + +--- + +## async — 비동기 executor 컨텍스트 전파와 포화 처리 + +### AsyncContextTaskDecorator +- **executor 경계를 넘을 때 caller 스레드의 컨텍스트를 worker 스레드로 옮기는 단 하나의 + `TaskDecorator`다.** MDC 는 submit 시점에 맵 전체를 복사한다(`MDC.getCopyOfContextMap()`). 그래서 + async 전파 대상 4개 foundation 키(`request_id`/`trace_id`/`correlation_id`/`tenant_id`)와 + `span_id`(SLF4J-Micrometer tracing bridge 가 MDC 에 써넣는 값)가 worker 로그 라인에 그대로 + 따라온다. 특정 상수 holder(`MdcKeys`)에 결합하지 않고 맵을 통째로 복사하는 이유는, 그래야 그 + 시점에 존재하는 모든 키를 빠짐없이 옮길 수 있기 때문이다. +- **domain 컨텍스트는 직접 복사하지 않고 shared seam(`DomainContextPropagator.wrap`)에 위임한다.** 이 + 브랜치는 executor 배선만 소유하고, caller→worker 의 실제 hand-off 는 seam 이 소유한다는 책임 분리에 + 따른 것이다. +- **trace/span "문자열"만 옮기지 Micrometer `Observation` scope 는 worker 스레드에서 다시 열지 + 않는다.** 그래서 로그 연속성은 유지되지만, worker 에서 새로 만든 child observation 은 caller 의 + span 아래로 nesting 되지 않는다. 완전한 scope 전파는 `io.micrometer:context-propagation` + Spring + 의 `ContextPropagatingTaskDecorator`가 필요한데, 그 라이브러리를 의도적으로 classpath 에 두지 + 않았다. 따라서 "수동 4-key copy decorator" 경로를 채택하고, worker 스레드 span 이 정말 필요한 + 프로젝트를 위해 라이브러리 업그레이드를 확장 지점(seam)으로 문서화해 둔다. +- **`SecurityContext` principal 은 일부러 전파하지 않는다.** `user_principal`은 전파 대상이 아니고, + pooled 로 재사용되는 worker 스레드에 `SecurityContext`를 복사하는 것은 stale-context 위험이기 + 때문이다. principal 이 worker 에서 진짜 필요한 use case 는 자기 executor 를 Spring Security 의 + `DelegatingSecurityContextTaskExecutor`로 감싸서 명시적으로 opt-in 한다. +- **decorator 는 대칭적이다.** 태스크 실행 후 worker 스레드의 이전 MDC 를 복원하므로, pooled + 스레드가 한 태스크의 컨텍스트를 다음 태스크로 흘리지 않는다. + +### AsyncExecutorConfig +- **Spring Boot 가 auto-config 하는 `applicationTaskExecutor`를 bounded pool 로 교체한다.** Boot 기본 + executor 의 큐는 unbounded(`Integer.MAX_VALUE`)라 금지된다. 빈 이름을 `applicationTaskExecutor`로 + 두는 이유는 Boot 의 `@ConditionalOnMissingBean(Executor.class)` auto-config 를 back-off 시키면서, + 동시에 `@Async`가 resolve 하는 바로 그 executor 가 되게 하기 위함이다. +- **TaskDecorator 미설정 executor 등록은 ApplicationContext 기동 실패로 만든다.** + `AsyncContextTaskDecorator`를 executor 빈의 *필수* 생성자 의존으로 두었기 때문에, decorator 없이 + executor 를 등록하려 하면 컨텍스트가 뜨지 않는다. +- **`awaitTerminationSeconds(19)`는 컨테이너 app-shutdown 예산 20s 에서 cleanup margin 1s 를 뺀 + 값이다.** 25s 는 금지된다 — 컨테이너가 강제 종료하기 전에 graceful drain 이 끝나야 하기 때문이다. +- **`executor.saturation` gauge 는 살아있는 큐 깊이를 읽는다.** 큐 > 용량 80% 면 p2, rejection + 발생이면 p1 알림 기준이다. + +### AsyncExecutorSettings +- **큐는 반드시 bounded 여야 한다.** unbounded 큐는 `maxPoolSize`를 도달 불가능하게 만든다 — JDK + `ThreadPoolExecutor`는 큐가 가득 찼을 때만 core 이상으로 스레드를 늘리기 때문이다. 게다가 Spring + `ThreadPoolTaskExecutor`의 큐 기본값은 `Integer.MAX_VALUE`, 즉 사실상 unbounded 다. 그래서 compact + 생성자가 큐 용량으로 `Integer.MAX_VALUE`를 거부한다 — 그만큼 큰 용량은 이름만 다른 unbounded + sentinel 이기 때문이다. +- **검증은 fail-fast(ApplicationContext 기동 실패)다.** 잘못 설정된 pool 은 런타임 fault 가 아니라 + deploy-time 버그이므로, 런타임까지 끌고 가지 않고 기동 시점에 즉시 터뜨린다. +- **cross-field 불변식: `maxSize`는 `coreSize`보다 작을 수 없다.** core 보다 작은 max 는 무의미하고, + pool 이 설정된 core 크기에조차 도달하지 못하게 만들기 때문이다. + +### BackgroundJobMetrics +- **이 브랜치가 소유하는 background-job/async-executor 메트릭 어휘 SSOT 다.** 메트릭 이름·태그는 + `docs/registries/metrics.yaml`과 verbatim 일치한다: `executor.saturation`(gauge, `executor_name`), + `executor.rejected.total`(counter, `executor_name`+`policy`), `job.retry.total`(counter, + `job_name`+`outcome`), `job.dlq.total`(counter, `job_name`). +- **`executor.*` 두 meter 는 `AsyncExecutorConfig`가 라이브로 배선하고, `job.*` 두 recorder 는 어휘 + 표면만 먼저 출시한다.** retry/DLQ 어휘는 outbox/outbound 브랜치가 나중에 retry carrier 를 고르면 + 소비하라고 이 브랜치가 소유한다. carrier 자체는 아직 정해지지 않았으므로, retry 엔진이 아니라 + vocabulary surface 만 출시하는 것이다. +- **`MeterRegistry` 빈이 없으면(=classpath 에 Actuator 없음) 모든 연산이 no-op 다.** `ObjectProvider`로 + registry 를 resolve 하며, 이는 `OutboxMetrics` 선례를 그대로 따른다. +- **`RetryOutcome` enum 은 retry 어휘를 type-safe 하게 표기한 것이다.** `job.retry.total`의 `outcome` + 태그 값은 metrics.yaml 에서 4개(SUCCESS/RETRY/EXHAUSTED/DLQ)로 bounded 되어 있고, 미래의 retry + carrier 가 이 값을 emit 한다. + +### LoggingAbortPolicy +- **기본 포화 정책은 `AbortPolicy`다.** bounded 큐가 가득 차고 pool 이 `maxPoolSize`에 도달하면 + 태스크를 거부하고 그 거부를 caller 에게 전달한다. 이 wrapper 는 bare + `ThreadPoolExecutor.AbortPolicy`가 빠뜨리는 두 가지 계약 의무를, abort 를 다시 던지기 *전에* + 추가한다: (1) `error.code=JOB_EXECUTOR_REJECTED` + category + `executor_name` + `policy`를 담은 + structured ERROR 로그, (2) `executor.rejected.total{executor_name, policy}` counter 증가. +- **그 다음 `RejectedExecutionException`을 던져 AbortPolicy 의미를 유지한다.** fire-and-forget + `@Async` caller 의 거부가 조용히 삼켜지지 않도록 하기 위함이다 — 이 예외가 async-exception 계약이 + 흡수하는 신호다. +- **허용되는 유일한 대안은 `CallerRunsPolicy`뿐이고, 그것도 명시적 use-case 선언이 있을 때만이다.** + caller-runs 의 back-pressure 는 request 스레드 latency 를 갉아먹기 때문이다. unbounded 큐는 아예 + 금지다. + +--- + +## idempotency — 멱등성 런타임 조립과 TTL 상한 + +### IdempotencyConfig +- **공유 `Clock` 빈과 `IdempotencyExecutor`를 composition root 에서 조립하고, `@EnableScheduling`으로 + 만료 레코드 reaper 의 스케줄 purge 를 켠다.** `Clock`을 빈으로 한 번만 정의해 executor·persistence + store 어댑터·reaper·rate-limit 인터셉터가 같은 시계를 쓰게 만들어 테스트에서 시간 고정이 쉽고 + 분기마다 시간 해석이 어긋나지 않는다. executor 를 여기서 만드는 이유는 TTL 같은 설정을 + `application-core`가 직접 읽으면 안 되기 때문이다. `@Scheduled` purge 는 `@EnableScheduling` 없이는 + 동작하지 않으므로 이 설정 클래스에서 명시적으로 활성화한다. + +### IdempotencySettings +- **TTL 기본값은 24h 이고 상한은 72h 이며, 이 상한 검사는 컴팩트 생성자에서 fail-fast 로 던진다.** + `Duration`의 상한은 JSR-303(`@Valid`) 애너테이션으로 표현할 수 없는 교차 필드 불변식이라 생성자에서 + 직접 검증한다. 검증을 느슨하게 두고 넘어가면 과도하게 긴 TTL 이 저장소를 조용히 부풀리고 멱등성 키 + 추측 공격의 유효 시간 창을 넓히기 때문에, 부팅 시점에 즉시 실패시키는 쪽을 택했다. +- **`MAX_TTL`(72h) / 기본 TTL(24h)을 바꿀 때는 보안 베이스라인의 JWT 키 회전 겹침(overlap) 윈도와 + 반드시 함께 검토해야 한다.** 멱등성 레코드의 수명이 키 회전 겹침 윈도(현재 24h)보다 길면, 가명화 + (pseudonym) 기준이 회전된 principal 에 대해 레코드가 재생(replay)될 수 있다. 이 불변식을 강제하는 + CI 게이트는 security-operational-baseline 쪽에 위임돼 있다. +- **`reaperInterval`은 전용 환경변수가 없고 기본 10분이다.** reaper 실행 주기는 비밀이나 배포별 값이 + 아니라 순수 운영 튜닝 값이라 env key 를 따로 두지 않고, 비어 있거나 0/음수면 10분으로 채운다. + +--- + +## lock — 분산 락 메트릭 데코레이터 배선 + +### DistributedLockConfig +- **`distributedLockProvider` 빈은 `ca-skeleton.runtime.multi-instance-enabled=true`일 때만 + `@ConditionalOnProperty`로 등록되고 `@Primary`로 우선 적용된다.** 다중 인스턴스 환경에서만 + `adapter-persistence`의 원시 `jdbcDistributedLock`(JdbcLockRegistry, Flyway 가 프로비저닝한 + `INT_LOCK` 기반) 어댑터를 `MeteredDistributedLockPort`로 감싸 `lock.acquisition` 카운터를 기록한다. +- **단일 인스턴스에서는 이 조건부 빈이 아예 없으므로 `adapter-persistence`가 등록한 `@Primary + inProcessDistributedLock`(in-process `DefaultLockRegistry`)이 그대로 선택된다.** 이 경로는 의도적 + 으로 계측하지 않는다 — `lock.acquisition` 카운터는 인스턴스 간 분산 조율을 관측할 때만 의미가 + 있고, JVM 안의 단순 뮤텍스에는 무의미하기 때문이다. +- **빈 이름 `"distributedLockProvider"`는 `StartupSafetyValidator`가 이름으로 조회해 검증하는 + 계약이다.** 절대 이름을 바꾸지 말 것. + +### MeteredDistributedLockPort +- **`DistributedLockPort`를 감싸는 얇은 Micrometer 데코레이터다.** `tryAcquire` 호출마다 + `lock.acquisition` 카운터를 `outcome` 태그와 함께 1 증가시킨다. 태그 값은 세 가지: `acquired`(락 + 획득 성공, 위임 핸들 반환), `timeout`(`LockAcquisitionTimeoutException` 발생), `error`(그 외 모든 + `RuntimeException` 발생). 메트릭 이름과 태그 값은 `docs/registries/metrics.yaml`의 `lock.acquisition` + 행과 일치해야 한다. +- **리스 만료(lease-expiry) CME 흡수.** 보유자가 `close()`를 호출하기 전에 리스(저장소 TTL)가 + 만료되면 그 락 행은 이미 다른 인스턴스가 회수해 갔을 수 있고, 그 시점에 내부 `JdbcLock.unlock()`은 + `ConcurrentModificationException`(CME)을 던진다. 이 예외를 호출자의 `finally { lock.close(); }` + 블록 밖으로 그대로 전파하면 보호 구간(critical section)에서 발생한 본래 예외를 가려버린다 + (masking). 그래서 CME 만 잡아 WARN 로그를 남기고 태그 없는 `lock.lease.expired` 카운터를 1 + 증가시킨 뒤 `close()`는 정상 복귀시킨다. 이렇게 해야 신호(로그+메트릭)는 남기면서도 호출자의 정상 + 흐름과 예외 전파를 방해하지 않는다. 오직 `ConcurrentModificationException`만 흡수하며, DB 장애 같은 + 다른 예외(예: `DataAccessResourceFailureException`)는 리스 만료 신호가 아니므로 손대지 않고 그대로 + 전파한다. +- **MeterRegistry 부재 시 no-op.** 레지스트리를 `ObjectProvider.getIfAvailable()`로 해석하므로 + 클래스패스에 `MeterRegistry` 빈이 없으면(Actuator 미탑재) 모든 메트릭 연산이 조용히 no-op 이 + 된다. `BackgroundJobMetrics` 선례와 동일한 패턴이다. +- **메트릭 실패가 락 경로를 절대 깨뜨리지 않음.** 카운터 등록·증가는 모두 try/catch 로 감싸 예외를 + 로깅 후 삼킨다(log-and-swallow). Micrometer 쪽 실패가 락 획득·보유·실패 보고를 막는 일은 없어야 + 하기 때문이다. + +--- + +## outbox — 트랜잭셔널 아웃박스 릴레이 와이어링 + +### OutboxConfig +- **릴레이 use case 를 `@Service`가 아니라 `app-bootstrap`에서 수동 조립한다.** + `PublishPendingOutboxEventsUseCase`는 `batchSize`와 `inFlightTimeout` 같은 설정값을 생성자로 받아야 + 하는데, `application-core`는 설정(`OutboxSettings`)을 직접 읽으면 안 된다. 그래서 설정을 볼 수 있는 + 합성 루트(`OutboxConfig`)가 값을 꺼내 use case 를 손으로 만들어 넘긴다. use case 클래스의 + `@UseCaseCapability` 애너테이션은 와이어링 방식과 무관하게 유지된다(ArchUnit 이 강제). +- **bootstrap은 failure reporter를 구현하지 않고 주입만 한다.** `MessagingConfig`가 broker 설정에서 + 정확히 하나의 `OutboxRelayFailureReportPort` 구현을 만들고, `OutboxConfig`는 이를 relay 생성자에 + 전달한다. broker가 비활성이어도 reporter bean은 존재한다. +- **릴레이 use case 를 독립 컨텍스트 빈으로 등록하지 않는다.** 만약 빈으로 올리면 `adapter-web`의 + `MethodSecurityConfig` 메서드 보안 pointcut(`@RequiresPermission`)이 이 타입을 CGLIB 프록시로 + 감싼다. 그런데 use case 가 `final` 클래스라 프록시 생성 자체가 실패하고, 설령 된다 해도 스케줄러 + 스레드에는 `Authentication`이 없어 매 릴레이 틱이 fail-closed 로 거부된다. 그래서 빈으로 올리지 + 않고, `outbox:relay` 권한 확인은 스케줄러 컨텍스트에서 관례로 둔다. +- **`outboxRelayScheduler` 빈은 `ca-skeleton.outbox.relay-enabled`로 게이팅한다(기본 true, + `matchIfMissing=true`).** 릴레이를 끄고 싶을 때 빈 자체가 만들어지지 않게 하기 위함. 키가 없으면 + 켜진 것으로 본다. +- **`outboxLeaderElection` 토큰 빈은 조건 없이(unconditional) 항상 등록한다.** `StartupSafetyValidator` + 가 `APP_MULTI_INSTANCE_ENABLED=true`일 때 이 빈을 반드시 찾을 수 있어야 하기 때문이다. SKIP + LOCKED 는 멀티 인스턴스 여부와 무관하게 언제나 릴레이의 리더십 메커니즘이라, `@ConditionalOnProperty` + 로 끌 수 있게 만들면 단순 조정 기능이 아니라 릴레이 정확성 자체가 깨진다. +- **`outboxMetrics` 빈은 `MeterRegistry`가 없을 때 no-op 이다.** Actuator 가 클래스패스에 없는 + 환경에서도 와이어링이 깨지지 않도록 `ObjectProvider`로 레지스트리를 선택적으로 주입한다. + +### OutboxLeaderElectionToken +- **로직이 전혀 없는 마커(documentation artifact) 빈이다.** 이 타입은 동작을 갖지 않고, Spring + 컨텍스트에 존재한다는 사실만으로 멀티 인스턴스 조정 빈 요구사항을 충족시킨다. +- **리더 선출을 외부 코디네이터 없이 PostgreSQL `FOR UPDATE SKIP LOCKED`로 구현한다는 것을 + 표현한다.** claim 쿼리에 SKIP LOCKED 를 걸면 각 릴레이 인스턴스가 서로 겹치지 않는(disjoint) 행 + 집합을 가져가므로, 별도 코디네이터 없이도 "각 인스턴스가 자기 파티션의 리더" 형태로 리더 선출 + 의미가 성립한다. + +### OutboxMetrics +- **`MeterRegistry`가 없으면 모든 메트릭 연산이 no-op 이다.** Actuator 가 없는 환경에서도 릴레이가 + 정상 동작해야 하므로, 생성자에서 `ObjectProvider`로 레지스트리를 조회해 없으면 게이지도 만들지 + 않고 기록도 건너뛴다. +- **카운터는 PUBLISHED/FAILED/DEAD 만 집계하고 IN_FLIGHT 는 제외한다.** IN_FLIGHT 는 릴레이 사이클의 + 종료 결과(terminal outcome)가 아니라 처리 중을 나타내는 일시적 상태라 카운터 outcome 으로 의미가 + 없다. +- **MultiGauge 갱신 시 `overwrite=true`로 등록한다.** 매 스케줄러 틱마다 store 를 다시 조회해 + 게이지를 갱신하는데, 이전 틱에 있었지만 지금은 사라진 event type 같은 오래된 time-series 태그를 + 덮어써 제거하기 위함이다. + +### OutboxRelayScheduler +- **합성 루트가 직접 등록하고 컴포넌트 스캔하지 않는다.** 이 스케줄러가 구동하는 릴레이 use case 가 + (위 OutboxConfig 사유로) 일부러 빈이 아니기 때문에, 그 use case 를 조립하는 `OutboxConfig`가 + 스케줄러 등록까지 같이 소유한다. +- **릴레이 사이클에서 발생하는 예상치 못한 예외를 잡아 ERROR 로 로깅만 하고 삼킨다.** 스케줄러 + 스레드가 죽으면 릴레이가 조용히 멈추므로, 다음 틱을 위해 스레드를 살려둔다. 단, 개별 발행 실패 + (FAILED/DEAD 전이)는 relay가 persisted transition 성공 뒤 typed reporter로 canonical ERROR를 + 요청하고 결과에 반영하므로 이 catch 블록까지 오지 않는다 — 여기서 삼키는 것은 어디까지나 + "예상치 못한" 예외다. +- **`@EnableScheduling`을 직접 켜지 않고 fixed-delay 를 쓴다.** 스케줄링은 이미 `IdempotencyConfig`를 + 통해 활성화돼 있어 중복으로 켤 필요가 없고, fixed-delay 는 릴레이 실행 시간과 무관하게 사이클이 + 겹치지 않도록(non-overlapping) 보장한다. + +### OutboxSettings +- **여섯 개 설정값 모두 코드 리터럴 기본값을 쓰고 env placeholder 를 두지 않는다.** 신규 env key 를 + 추가하지 않는다는 결정에 따라, 값이 없으면 컴팩트 생성자에서 직접 기본값(예: `PT5S`, `20`, + `PT5M`, `PT10M`, `P7D`)을 채운다. +- **`reaper-interval`과 `published-retention`은 `adapter-persistence`의 `OutboxReaper`도 property + 문자열로 읽는다.** 두 모듈이 같은 키를 공유하지만, 이 properties record 가 여섯 값 전체를 문서화 + 하는 단일 지점(single place) 역할을 한다. + +--- + +## logging — 로그 시크릿 마스킹·샘플링·가명화 + +### LogMaskingPatterns +- **마스킹 정규식 규칙을 한 곳에만 둔 단일 진실 원천(SSOT)이다.** JSON 인코더 경로 + (`SecretMaskingJsonGeneratorDecorator`, staging/prod/default 프로파일)와 사람이 읽기 쉬운 패턴 경로 + (`SecretMaskingMessageConverter`, local/dev)가 같은 규칙을 공유한다. 규칙을 한 군데로 모아둔 이유는, + 프로파일이나 로그 포맷을 바꿔도 가려지는 시크릿의 범위가 절대 달라지지 않게 하기 위해서다. 즉 + "가독성을 위해 포맷을 바꿨더니 시크릿이 다시 노출되는" 사고를 구조적으로 막는다. +- **시크릿 값만 가리고 키/스킴은 남긴다.** `token=abc123` → `token=****`, + `Authorization: Bearer eyJ...` → `Authorization: Bearer ****`처럼 동작한다. 키와 인증 스킴(`Bearer` + 등)을 남기는 이유는 진단할 때 "어떤 종류의 자격증명이 있었는지"는 알아야 하기 때문이다. +- **정규식 마스킹은 보증이 아니라 심층 방어(defence-in-depth)의 보조 수단이다.** 1차 방어선은 + "로거가 애초에 본문/페이로드를 받지 않도록 설계한 것"(`FailOpenDependencyLogger`)이고, 이 정규식은 + 그걸 빠져나간 누출을 잡는 그물이다. 키 접두어 없는 Base64URL 블롭 같은 난독화된 형태는 놓칠 수 + 있으므로, 새로운 누출 형태가 보이면 이 규칙 목록을 운영 중에 계속 보강해야 한다. + +### MetricsAsyncAppender +- **백프레셔로 로그가 버려질 때 그 사실을 메트릭으로 노출한다.** Logback `AsyncAppender`는 큐 여유가 + `discardingThreshold` 아래로 떨어지면 `INFO`/`DEBUG` 같은 낮은 심각도 이벤트를 조용히 버린다 + (`WARN`/`ERROR`는 항상 보존). 이렇게 조용히 사라지는 드롭은 관측이 안 되면 장애 분석 때 "로그가 + 비어 있는데 왜 비었는지 모르는" 상황을 만들기 때문에, 버릴 때마다 `log.appender.dropped.total` + Micrometer 카운터를 올리고(`appender`·`level` 태그) 그다음 상위 클래스에 실제 드롭을 위임한다. +- **카운터를 `Metrics.globalRegistry`로 발행한다.** Logback 은 Spring 컨텍스트보다 먼저 초기화되는데, + Spring Boot 가 시작 시 애플리케이션 `MeterRegistry`를 이 전역 컴포지트에 합류시킨다. 그래서 초기화 + 순서가 어긋나도 결국 평소 메트릭 엔드포인트에서 이 수치가 보인다. +- **`level` 태그를 `INFO`/`DEBUG`로만 한정한다.** `metrics.yaml`의 `allowed_values` 계약 때문이다. + 루트 레벨을 TRACE 로 낮춰야만 가능한 `TRACE` 드롭은 상위 클래스가 여전히 버리지만 카운트하지는 + 않아서, 태그 카디널리티가 레지스트리 계약을 벗어나지 않게 유지한다. + +### PseudonymizationConfig +- **`user_principal`(로그에 남는 사용자 식별자)를 전체 HMAC 방식으로 가명화한다.** + `UserPrincipalPseudonymizerPort`(application-core)를 HMAC-SHA-256 구현(adapter-identifier)에 + 바인딩하고, 솔트는 `PrivacySettings`에서 가져온다. 원본 식별자를 그대로 로그에 남기지 않으려는 + 개인정보 보호 결정이다. 실제 사용처는 `adapter-web`의 `RequestLoggingFilter`로, 보안 principal 이 + MDC/로그에 닿기 전에 이 포트로 가린다. +- **`@ConditionalOnMissingBean`으로 기본 구현을 둔다.** 이 템플릿을 포크한 프로젝트가 자기만의 + 가명화기(예: 향후 솔트 회전을 지원하는 구현)를 등록하면 이 기본 빈이 비켜주도록, 즉 기본값은 + 제공하되 교체를 막지 않도록 하기 위해서다. + +### SamplingTurboFilter +- **레벨을 의식하는 로그 샘플러다.** `WARN`/`ERROR`는 절대 샘플링하지 않고 항상 통과시킨다 + (`FilterReply.NEUTRAL`). 진단·장애 신호인 경고/오류는 100% 보장해야 하고, 샘플링 대상은 `INFO` + 이하만이라는 정책 때문이다. `INFO` 이하는 확률 `rate`로 보존하고 나머지는 `FilterReply.DENY`로 + 버린다. +- **단일 `rate` 노브로 제어한다.** `APP_LOG_SAMPLING_RATE`(logback `springProperty`)에서 주입되고, + 운영자가 프로파일별로 설정한다(prod `0.1` = INFO 10% 샘플링, staging/dev/local `1.0` = 전부 보존). + 고트래픽 vs 일반 엔드포인트의 더 세밀한 분기는 이 전역 rate 위에 마커 기반 확장으로 문서화만 되어 + 있고 여기서는 구현하지 않았다. +- **검증은 "경고 후 기본값(warn-and-default)" 방식이다.** `rate`가 `[0.0, 1.0]` 범위를 벗어나면 + Logback 상태 시스템에 경고를 남기고 `1.0`(전부 보존)으로 폴백한다. 잘못된 설정이 로그를 소리 없이 + 버리는 쪽으로 가지 않고, 항상 안전한 "샘플링 안 함"으로

`LogstashEncoder`에 연결된다. + JSON 생성 시점에 마스킹하기 때문에 어떤 구조화 필드가 시크릿을 담았든 상관없이 message·MDC + 값·스택 트레이스 텍스트 등 모든 문자열 값을 덮는다. 이 "어디서 새든 잡는 그물(catch-net)" 성질이 + Redaction Layer 1에 요구되는 핵심이다. + +###

방어 필터다.** 미터의 `Meter.Id`에 붙은 태그 키 중 + 하나라도 `ForbiddenMetricTags.FORBIDDEN`에 들어 있으면 그 미터를 `DENY`하고, 아니면 `NEUTRAL`을 + 반환한다. `user_id`, `request_id`, `raw_url`, `raw_query`, `raw_header_value`, `ip_address` 같은 + 고카디널리티(high-cardinality) 라벨 키는 고유 값마다 Prometheus 시계열을 하나씩 만들어 수백만 + 개로 폭증할 수 있어 차단한다. +- **이 필터는 카디널리티 계약의 런타임(runtime) 절반이다.** 정적(static) 절반은 레지스트리 계약 + 테스트(`MetricsAlertingContractTest`)가 담당한다 — 둘이 짝을 이뤄 심층 방어를 구성한다. +- **상태가 없어(stateless) 여러 레지스트리에 공유해도 안전하다.** public no-arg 생성자는 + `MetricsContractConfig.install()`이 직접 인스턴스화하기 위한 계약이다. + +### MetricsContractConfig +- **`@PostConstruct`에서 `MeterFilter`들을 `MeterRegistry`에 직접 설치한다.** `@Bean MeterFilter`로 + 등록하지 않는 이유: 이 템플릿 클래스패스에는 `@Bean MeterFilter`를 자동 수집하는 Spring Boot + Actuator 자동설정(`MeterRegistryCustomizer`)이 없어서 `@Bean MeterFilter`는 그냥 동작하지 않는 + (inert) 죽은 빈이 되기 때문이다. `OutboundHttpResilienceConfig`에서 확립한 선례를 따른다. +- **설치 순서가 중요하다.** (1) `MetricsCardinalityMeterFilter`(deny-list)를 먼저 설치해 금지 태그가 + 붙은 미터가 분포 필터에 닿기 전에 거부되도록 하고, (2) 그다음 `MetricsDistributionMeterFilter` + (SLO 기반 히스토그램 설정)를 설치한다. +- **필터는 설치 이후 등록되는 미터에만 적용된다.** `@PostConstruct`는 Spring 빈 생명주기 중 애플리 + 케이션 코드가 어떤 미터든 등록하기 전에 실행되므로 모든 미터가 필터 적용 대상이 된다. +- **`MeterRegistry` 부재 시 no-op.** `ObjectProvider.getIfAvailable()`로 해석해 레지스트리 빈이 + 없으면(Actuator 미탑재) DEBUG 로그만 남기고 설치를 건너뛴다. +- **`install(MeterRegistry)`를 public static 으로 둔 이유.** 계약 테스트가 Spring 컨텍스트 없이 + `SimpleMeterRegistry`에 대해 직접 구동할 수 있게 하기 위함이다. + +### MetricsDistributionMeterFilter +- **소유한(owned)

**히스토그램 전략은 두 축이다.** + - *인스턴스 간 집계 가능한 진실의 원천*: `percentilesHistogram(true)`(= `publishPercentileHistogram`)가 + `_bucket` 시계열을 생성하고, Prometheus 에서 `histogram_quantile()`로 인스턴스 간 집계할 수 있다. + 이것이 다중 인스턴스 배포의 정식 p50/p95/p99 다. + - *클라이언트 측 편의값(집계 불가)*: `percentiles(0.5, 0.9, 0.95, 0.99)`(= `publishPercentiles`)는 + 단일 인스턴스 가시성을 위한 사전 계산 분위 게이지를 제공한다. 이 값들은 인스턴스 간 평균을 내면 + 안 된다(통계적으로 틀림). 인스턴스 간 집계는 반드시 `histogram_quantile()`로 한다. +- **SLO 경계값 `100ms / 500ms / 1s / 5s`는 잠정 SLO 역산이며 외부 표준에서 유도한 값이 아니다.** + 정식 SLO 가 채택되면 재검토 대상이다. 함께 설정하는 `minimumExpectedValue=1ms`, + `maximumExpectedValue=10s`는 히스토그램 버킷의 관측 범위를 한정한다. +- **상태가 없어 여러 레지스트리에 공유해도 안전하고,** public no-arg 생성자는 + `MetricsContractConfig.install()`이 직접 인스턴스화하기 위한 계약이다. + +--- + +## management/security — 액추에이터 엔드포인트 보안 체인 + +### ManagementSecurityConfig +- **`actuatorSecurityFilterChain`은 `@Order(0)`으로 메인 앱 체인(adapter-web `SecurityConfig`)보다 + 앞서 실행된다.** 그래서 액추에이터 엔드포인트에 매칭되는 요청은 앱 체인이 아니라 이 체인이 + 처리한다. 보안 매처는 `EndpointRequest.toAnyEndpoint()`로, 관리 포트의 `/actuator/**` 경로만 이 + 체인 범위에 든다. +- **접근 정책.** `health`, `info`, `prometheus`는 permit-all 이다. 자격 증명 없이 Kubernetes 프로브와 + Prometheus 스크레이프가 접근할 수 있어야 하고, 이 엔드포인트들은 민감 데이터를 노출하지 않기 + 때문이다(health 상세는 when-authorized). 나머지 액추에이터 엔드포인트는 모두 인증이 필요하다. +- **`loggers` 쓰기 차단.** 런타임 로그 레벨 변경은 `POST /actuator/loggers/{name}`이고, 레벨 리셋은 + `DELETE /actuator/loggers/{name}`이다. 둘 다 변형(mutation) 작업이므로 `denyAll()`로 모두에게 + (인증된 사용자 포함) 거부한다 — 인증만으로 쓰기 권한을 주지 않는다. `loggers` 읽기는 아래 + `authenticated()`로 흘러 인증을 요구한다. +- **인증 실패 시 기본값 403 대신 401(자격 증명 필요)을 반환한다(`HttpStatusEntryPoint(UNAUTHORIZED)`).** + 대화형 로그인이나 basic-auth realm 은 제공하지 않는다 — 관리 포트는 네트워크 ACL 뒤에 있으므로 + 올바른 HTTP 의미(credentials required)만 신호하면 된다. +- **운영에서 deny-by-default 보장은 관리 포트를 별도 포트로 분리해 네트워크 ACL 수준에서 강제한다.** + 이 in-process 체인은 그 위의 심층 방어 계층이다. +- **SHAPE-OWNERSHIP(하드 규칙): 이 클래스는 `HealthEndpoint` / `HealthIndicator` / `HealthComponent`를 + import·구현·의존해선 안 된다** — health 엔드포인트의 형태(shape)는 runtime-health 브랜치 소유다. + 보안 매칭은 오직 엔드포인트 id 문자열로만 하고 health 내부 구조에는 절대 손대지 않는다. ArchUnit + 규칙 `management_security_does_not_depend_on_health_internals`(`CleanArchitectureTest`)가 이를 정적 + 으로 강제한다. + +--- + +## tracing — 분산 트레이싱 wiring과 샘플링 정책 + +### TracingConfig +- **컴포지션 루트에서 트레이싱을 조립한다.** 두 가지를 한다: (1) 시작 시 `tracing.sampling.rate` + 게이지 등록, (2) `SpanErrorRecorder` 빈 등록. +- **`SpanErrorRecorder` 빈은 `@ConditionalOnBean(Tracer.class)`가 아니라 `ObjectProvider<Tracer>`로 + 런타임 존재 여부를 직접 조회한다.** 이유: `@ConditionalOnBean`은 사용자 정의 `@Configuration`에서 + autoconfiguration 이 만드는 빈(여기서는 `Tracer`)을 조건으로 쓸 때 빈 등록 순서가 보장되지 않아 + 신뢰할 수 없기 때문이다. `Tracer`가 있으면 `MicrometerSpanErrorRecorder`를, 없으면 + `SpanErrorRecorder.NOOP`을 반환한다. +- **`@ConditionalOnMissingBean(SpanErrorRecorder.class)`를 붙여, 테스트 mock 이나 fork 가 자체 + `SpanErrorRecorder` 빈을 이미 등록한 경우 이 빈은 backoff 한다.** adapter-web 의 + `GlobalExceptionHandler`는 `ObjectProvider`로 `SpanErrorRecorder`를 조회하므로, 자기 자신의 NOOP + self-default 에서 여기서 등록한 실제 구현으로 자동 교체된다. +- **OTel/Micrometer tracer 런타임은 이 repo 에서 seam 이 활성 상태다.** `micrometer-tracing-bridge-otel` + + `opentelemetry-exporter-otlp`가 `app-bootstrap/build.gradle`에 실제로 wiring 되어 있다. 단, span + exporter 는 `OTEL_EXPORTER_OTLP_ENDPOINT`가 비어 있는 동안 꺼져 있고, 엔드포인트를 설정하면 + export 가 시작된다. +- **게이지 등록 시 active profile 은 `Environment.getActiveProfiles()`의 첫 번째 값을 쓴다.** 멀티 + 프로파일 배포에서는 맨 앞에 나열된 프로파일이 권위 있는 배포 환경이라는 규약이다. `MeterRegistry`가 + classpath 에 없으면(Actuator 미탑재) 게이지 등록은 조용히 no-op 이 된다. +- **`TracingSamplingRateGaugeRegistrar` record 는 등록된 active profile 과 resolved rate 를 노출하는 + 값 홀더다.** 정식 포트나 use case 가 아니라, 살아있는 `MeterRegistry` 없이도 테스트가 "무엇이 + 등록되었는지" 검사할 수 있게 하는 bootstrap 내부 전용 장치다. + +### TracingSettings +- **`ca-skeleton.tracing.*` 바인딩 `@ConfigurationProperties` record.** 세 env 키가 들어온다: + `APP_TRACING_ENABLED` → `enabled`, `APP_TRACING_SAMPLE_RATE` → `sampleRate`, + `OTEL_EXPORTER_OTLP_ENDPOINT` → `exporter.otlpEndpoint`. +- **`sampleRate`가 blank 이면 숫자 검증을 건너뛴다.** blank 는 "값이 잘못됐다"가 아니라 "프로파일별 + 기본값에 위임하라"는 신호이기 때문이다. 실제 프로파일별 기본값(prod=0.01, staging=0.10, + dev/local=1.0)은 `TracingSampleRateResolver`가 소유하고, resolved 된 값은 + `TracingSamplingEnvironmentPostProcessor`가 Spring Boot 네이티브 + `management.tracing.sampling.probability`로 브리지한다. +- **검증은 시작 시 fail-fast 다.** `sampleRate`가 non-blank 인데 [0.0, 1.0] float 이 아니면 시작이 + 실패하고, `otlpEndpoint`가 non-empty 인데 scheme 없는 잘못된 URL 이면 시작이 실패한다. `enabled`는 + Spring 바인딩이 `boolean` 타입을 강제하므로 추가 검증이 필요 없다. `otlpEndpoint`가 비어 있으면 + exporter off 상태(seam 기본값)이고, 이것이 정상 동작이므로 검증을 통과시킨다. +- **`sampleRateValue()`는 호출 전 `sampleRate().isBlank()` 확인이 caller 규약이다.** blank 인 상태로 + 호출하면 `IllegalStateException`을 던지는데, 이는 파싱 오류가 아니라 caller 규약 위반을 드러내기 + 위한 것이다. + +### TracingSampleRateResolver +- **프로파일별 트레이싱 샘플 비율 SSOT 다.** prod=0.01(1%), staging=0.10(10%), dev/local=1.0(100%), + 그 외=1.0. `APP_TRACING_SAMPLE_RATE`가 non-blank 이고 [0,1] float 로 파싱되면 프로파일 기본값을 + override 한다. +- **Spring 의존성이 전혀 없는 순수 Java 로 작성했다.** 어떤 컨텍스트도 없이 단위 테스트할 수 있고, + `EnvironmentPostProcessor`(컨텍스트 생성 이전 단계)와 `TracingConfig`(빈 생성 단계) 양쪽에서 동일 + 로직을 재사용하기 위함이다. + +### TracingSamplingRateGauge +- **`tracing.sampling.rate` 게이지를 등록한다.** metric 계약: type=gauge, tag=`profile`(prod/staging/ + dev/local 허용), value=resolved effective sample rate(double in [0.0, 1.0]). +- **오직 active Spring profile 의 시리즈 하나만 방출하므로 cardinality 는 1이다.** tag 는 프로파일 + 이름을 정규화하지 않고 그대로 쓴다. 따라서 비표준 프로파일(예: "qa")로 띄워도 시리즈 하나는 정상 + 방출되고, 단지 4-value allowlist 를 벗어날 뿐이다 — 이는 런타임 에러가 아니라 레지스트리 문서상의 + 관심사다. +- **`MeterRegistry`를 `ObjectProvider`로 조회하며, Actuator 미탑재로 빈이 없으면 등록을 조용히 + 건너뛴다.** 이는 `BackgroundJobMetrics` / `OutboxMetrics`의 선례를 그대로 따른다. + +### TracingSamplingEnvironmentPostProcessor +- **resolved 된 유효 샘플 비율을 Spring Boot 네이티브 키 `management.tracing.sampling.probability`로 + 단일화(브리지)하는 `EnvironmentPostProcessor`다.** 이를 통해 "프로파일별 기본값 + env override"라는 + 우리 규약을 Spring Boot 의 기본 샘플링 메커니즘에 그대로 연결한다. +- **브리지 우선순위.** (1) 사용자가 `management.tracing.sampling.probability`를 이미 명시했으면 + 덮어쓰지 않고 그대로 둔다, (2) `ca-skeleton.tracing.sample-rate`가 non-blank 면 그 값 사용, (3) + blank 면 `TracingSampleRateResolver.defaultRateForProfile(...)`로 active profile 기본값 적용. +- **`META-INF/spring.factories`에 `org.springframework.boot.EnvironmentPostProcessor` 키로 등록된다.** + `EnvironmentPostProcessor`는 ApplicationContext 가 생성되기 전에 실행되므로 일반 빈이 아니라 + Spring Boot bootstrap factory 로 등록해야 한다. + +### MicrometerSpanErrorRecorder +- **NOOP 을 대체하는 Micrometer/OTel 기반 실제 `SpanErrorRecorder`다.** 현재 span 에 예외와 + `error.code` 태그를 기록한다. 계약 이행: `Span.error(Throwable)` 호출(OTel bridge 를 통해 + `recordException` + span status ERROR 매핑), `span.tag("error.code", errorCode)`(ca-tmpl 레지스트리 + 속성명), null `error`는 방어적 no-op, 현재 span 이 없으면 no-op. +- **"sampled span 에만 스택트레이스 부착" 정책은 의도적으로 구현하지 않았다.** Micrometer Tracing + 추상화 레벨에서는 sampled 여부를 직접 제어할 수 없기 때문이다(`Span.isNoop()`은 OTel NOOP span + 여부일 뿐 sampling 여부가 아니다). 다만 OTel SDK 의 unsampled span 은 이미 no-op 으로 처리되므로 + 명시적 sampled-only 분기가 없어도 실제 성능 부담은 없다. + +--- + +## settings — @ConfigurationProperties 검증 정책 + +이 모듈의 설정 record 들은 대체로 두 가지 검증 전략 중 하나를 고른다: **fail-fast**(잘못되면 기동 +중단)와 **warn-and-default**(경고만 남기고 안전한 기본값으로 진행). 어느 쪽을 쓰는지가 각 record 의 +핵심 결정이다. + +### BootstrapSettings +- **`appName`은 비어 있으면 시작을 실패시킨다(fail-fast).** `ca-skeleton.bootstrap.*` 바인딩이며, + 앱 이름은 운영자가 직접 제공해야 하고 합리적인 기본값이 존재하지 않으므로, 비어 있거나 blank 면 + `@NotBlank`로 막는다(Spring Boot 가 `BindValidationException`을 띄우고 컨텍스트 기동을 거부). + 다른 settings 의 "warn-and-default"와 달리 여기서 fail-fast 를 택한 이유는, 잘못된 앱 이름으로 + 조용히 기동되는 것보다 즉시 멈추는 편이 안전하기 때문이다. + +### LoggingSettings +- **모든 항목이 "warn-and-default" 정책이다.** `ca-skeleton.logging.*` 바인딩(원천은 .env). 잘못된 + 값은 경고 로그를 남기고 안전한 기본값으로 진행할 뿐 시작을 실패시키지 않는다. +- **fail-fast 대신 warn-and-default 를 택한 이유.** Logback 은 이 record 가 바인딩되기 전에 자기 + 초기화 단계에서 `<springProperty>` 바인딩으로 이미 같은 값들을 자체 기본값과 함께 소비했다. 따라서 + 이 record 의 역할은 로깅을 다시 강제하는 것이 아니라, 입력이 잘못됐을 때 운영자에게 명확한 경고를 + 표면화하는 것이다. +- **size 문자열(`maxSize`, `totalSizeCap`)은 검증하지 않는다.** 이 값들의 파싱 계약은 logback 이 + 소유하므로 logback 에게 맡긴다. + +### PrivacySettings +- **보안/감사 로그에서 `user_principal`을 가명화하는 데 쓰는 HMAC salt 를 보관한다.** + `ca-skeleton.privacy.*` 바인딩(원천 `APP_PRIVACY_PSEUDONYMIZATION_SALT`). 알고리즘은 HMAC-SHA-256 + + 90일 회전 salt 이고, 이 salt 는 `secret`-tier 값이라 prod 에서는 반드시 secret manager 에서 + 공급되어야 한다. +- **검증은 `LoggingSettings`와 일관되게 "warn-and-default"다.** blank salt 는 경고를 남기고, 명확히 + 표시된 dev sentinel(`__LOCAL_DEV_` 접두사)로 폴백해 local/test 실행이 절대 기동에 실패하지 않게 + 한다. +- **이 sentinel 을 prod 로 승격하는 것은 별도 계약이 독립적으로 + 차단한다** — prod 프로파일에서 `__LOCAL_DEV_` 값이면 시작이 실패한다. 그 게이트는 이 record 의 + 책임 밖이라 여기서 중복 강제하지 않는다. + +### RuntimeSafetySettings +- **시작 시 `StartupSafetyValidator`가 강제하는 운영 안전 토글이다.** `ca-skeleton.runtime.*` + 바인딩(원천 `APP_ERROR_DETAIL_EXPOSURE_ENABLED`, `APP_LOG_BODY_CAPTURE_ENABLED`, + `APP_MULTI_INSTANCE_ENABLED`, 모두 기본값 `false`). +- **`errorDetailExposureEnabled` / `logBodyCaptureEnabled`는 prod-unsafe 토글이다.** `prod` + 프로파일에서 둘 중 하나라도 켜면 시작이 실패한다. 그래야 내부 에러 상세나 요청 본문 캡처가 + 프로덕션에서 조용히 켜진 채 남는 일이 없다. +- **`multiInstanceEnabled`가 `true`면 인스턴스 조율 capability 빈들(lock / cache-stampede / leader / + rate-limit / migration)이 모두 존재하는지 단언하고, 하나라도 없으면 시작을 실패시킨다.** 멀티 + 인스턴스 모드를 켜놓고 조율 인프라가 빠진 채 기동되는 위험한 상태를 막기 위함이다. + +--- + +## build.gradle — 의존성 구성 근거 + +app-bootstrap 은 합성 루트라 "왜 이 의존성이, 왜 이 scope 로" 결정이 많다. 빌드 파일에는 한 줄 +요약만 두고, 비자명한 근거는 여기에 모은다. 바탕 원칙은 **api vs implementation 정책**(CLAUDE.md): +모듈 간 의존은 기본 `implementation`이라 transitive 로 새지 않는다 — 그래서 테스트에서 그 타입이 +필요하면 여기서 **명시적으로** 다시 선언한다. + +### 런타임(production) 의존성 +- **`flyway-core`를 직접 의존하는 이유.** PostgreSQL vendor 모듈이 `flyway-database-postgresql`와 + 마이그레이션 스크립트를 소유하지만, 합성 루트는 Flyway API 자체가 필요하다. `MigrationStartupConfig`의 + `migrationStartupRunner`(FlywayMigrationStrategy)가 `migrate()`를 직접 구동하고 `FlywayException`을 + exit-70 `MigrationFailedException`으로 번역하기 때문이다. +- **`spring-boot-starter-security`를 compile classpath 에 두는 이유.** adapter-web 이 security 를 + `implementation`(not `api`)으로 선언해서 Spring Security 타입이 app-bootstrap 컴파일 경로로 새지 + 않는다. 그런데 `ManagementSecurityConfig`가 `HttpSecurity`/`SecurityFilterChain`/`EndpointRequest`를 + 쓴다. cross-cutting 보안 와이어링은 합성 루트가 소유한다는 원칙(AGENTS.md)에 따라 여기서 직접 + 의존한다. +- **`micrometer-core`** — `OutboxMetrics` 카운터/게이지용. `ObjectProvider<MeterRegistry>`라 registry + 가 없으면 no-op 이다(registry 는 Actuator 가 제공). +- **tracing(`micrometer-tracing-bridge-otel` +

`runtimeOnly`가 아니라 `implementation`으로 올린 이유.** 보통 JSON + 로그 인코더는 런타임에만 있으면 되지만, `StartupFailures`가 `StructuredArguments`를 **compile + time**에 호출해 `startup.phase`/`error.code`/`error.category` JSON 필드를 방출하므로 compile + classpath 에 있어야 한다. + +### 테스트 의존성 (transitive 로 안 새서 명시 선언) +- **`testImplementation project(':adapter-persistence-postgresql')`** — vendor 클래스 + (`PostgreSqlSqlStateErrorMapping`/`PostgreSqlOutboxClaimRepository`)를 test compile 경로에 올려, + full-matrix contract 테스트가 실제 production composition 을 배선하게 한다(런타임 의존은 `runtimeOnly`). +- **`testRuntimeOnly

`implementation`이라 안 샌다. `DistributedLockProviderContractTest`가 같은 Testcontainers PG + DataSource 에 대해 독립 registry 두 개(= 두 인스턴스 시뮬레이션)를 직접 만들어 상호배제·리스 만료를 + 검증한다. 테스트 전용 — production 와이어링은 전부 `DistributedLockPersistenceConfig`(rdbms) 소유. +- **`spring-boot-starter-json`** — `JacksonAutoConfiguration`은 jackson-databind 가 test 경로에 있어야 + 활성화되고, deserialization-policy 경계 테스트가

TransactionPort 호출 경로로 라우팅하는 per-use-case 선택 메커니즘은 + 관련 추상화 설계와의 공동 변경이라 아직 `planned` 다. + 그전까지 이 상수들은 **어휘만** 선언하고, 실제 호출 경로는 `READ_COMMITTED` 로 고정된다. + +--- + +## 인가 (security) + +인증("누구냐")은

**replay** — `COMPLETED` record 는 저장된 응답을 codec 으로 재생(§B). + 4. **in-flight wait** — 동시 `IN_FLIGHT` record 는 최대 `IN_FLIGHT_WAIT`(200ms) 동안 폴링하고, + 여전히 미해결이면 `IdempotencyInFlightException` → 409(D7). +- claim 한 action 이 예외를 던지면 in-flight record 를 `discard` 한다 — 그래야 재시도가 TTL + 만료까지 409 에 갇히지 않는다. +- **200ms 대기 창의 출처(표준이 강제한 값 아님 — 스켈레톤 기본 선택)**: 이 200ms 대기 창은 + 인용 가능한 표준이 강제하는 값이 아니다(IETF/Toss 는 즉시 409 를 권장). 표준의 운영 친화적 + 변형이다 — "표준 기반 + 운영 변형" 으로 설명해야지 "표준을 따른다" 고 말하면 안 된다. 블로킹 + 폴링이 요청 스레드를 점유하므로, 중복 도착이 몰리면 스레드 점유 vs 클라이언트 재시도 친화성의 + 트레이드오프가 있다(임계치는 부하 테스트로 검증 필요). +- 상수: `IN_FLIGHT_WAIT = 200ms`(D7), `MAX_TTL = 72h`(D6 하드 캡), `POLL_INTERVAL = 20ms`. +- package-private 한 `Sleeper` 주입 생성자가 따로 있는 이유: 테스트 `Sleeper` 가 mutable clock 을 + 전진시켜 실제 시간 블로킹 없이 in-flight wait 를 결정적으로 검증하기 위함. + +### IdempotencyStorePort + +- 멱등 record 저장 outbound 포트(D3). `adapter-persistence` 가 유니크 제약 + `(tenant, principal, idempotency_key, use_case_name)` 위에 구현한다. 포트는 저장 primitive + (tryBegin/find/complete/discard)만 노출하고, 정책은 executor 가 가진다. +- **in-memory 프로덕션 구현 금지**: 계약상 내구성 있고 유일성을 강제하는 백킹 스토어가 필요하다. + Redis 는 내구 스토어 앞단의 선택적 캐시로만 허용된다. +- **만료 record 는 reclaimable**: `expiresAt <= now` 인 record 는 없는 것처럼 취급해야 한다. + `tryBegin` 은 만료된 죽은 행을 purge/replace 해서 새 claim 이 이기게 하고, `find` 는 만료된 + record 를 absent 로 보아 만료 replay 를 거부한다(§E / TTL 경계). + +### IdempotencyScope + +- 멱등 요청의 정체성이자 계약의 SSOT scope 모양(D2). 기본은 triple + `(authenticatedPrincipal, idempotencyKey, useCaseName)`. 테넌트 격리가 활성이면 `tenant` 차원을 + 앞에 붙인 4-tuple 이 되고, single-tenant 모드에선 `tenant = null`. +- **여기서 막는 실패 모드**: `principal`/`useCaseName` 이 빠진 key 는 전역적으로 충돌해 다른 + caller 의 응답을 재생할 수 있다. `of` 팩토리가 blank 필수 차원을 `IdempotencyScopeMissingException` + 으로 거부해, scope 없는 key 가 store 에 닿지 못하게 막는다. 막으려는 실패 모드는 "scope 누락으로 + 인한 silent 전역 충돌"이다. +- `storageKey()` 는 진단/단일 컬럼 조회용으로 사람이 읽는 join 문자열일 뿐이다. 유일성은 차원 + 컬럼에 강제되지 이 문자열에 강제되지 않는다. + +### RequestFingerprint + +- 요청 body 의 SHA-256 지문(D8). 같은 scope

SHA-256 을 골랐다 — 인용 가능한 표준이 강제한 것도, 측정된 성능 근거가 있는 것도 아니다. body + **정규화**(JSON 키 순서·공백·인코딩)는 의도적으로 적용하지 않는다 — 전송된 raw 바이트를 그대로 + 해시한다. 정규 동등성이 필요한 caller 는 `ofSha256` 호출 전에 직접 정규화해야 한다. 안 하면 키 + 순서만 바뀐 의미상 동일 replay 가 false mismatch 가 된다(부하와 실제 요청 형태로 검증 필요). +- `NoSuchAlgorithmException` catch 는 도달 불가다(SHA-256 은 모든 JDK 에 필수). 그래서 + `IllegalStateException` 으로 감싼다. + +### 멱등성 값/계약 타입 (Context ·

— 유스케이스 결과를 `StoredResponse` payload 로 직렬화/역직렬화. + application 은 wire-format 중립이다 — 구체 JSON 인코딩은 `R` 의 응답 모양을 아는 `adapter-web` + caller 가 소유하고, executor 는 그 문자열을 store 로 왕복시키기만 한다. +- `IdempotencyStatus` — `IN_FLIGHT` / `COMPLETED` 두 값. +- `Sleeper` — `Thread.sleep` 우회 인터페이스. executor 의 in-flight 폴링 대기를 결정적으로 + 테스트하기 위함(테스트 Sleeper 가 실제 시간 블로킹 대신 mutable clock 전진). + +### 멱등성 예외 3종

안에서 호출하며, 구현은 자체 트랜잭션을 열지 않는다. +- **claim 의미(I4 / I6)** — `claimBatch` 가 적격 행을 atomic 하게 `IN_FLIGHT` 로 전이시킨다: + - 적격 행: `PENDING`, `next_attempt_at <= now` 인 `FAILED`, `next_attempt_at <= now` 인 + `IN_FLIGHT`(고아 in-flight — I6 timeout 재사용). + - **FIFO 게이트(I4)**: 같은 `aggregate_id` 의 더 이른 `occurred_at` 행이 아직 `PUBLISHED` 가 + 아니면 그 aggregate 의 뒤 행들은 skip 한다. `DEAD` 행도 그 aggregate 큐를 막는다(strict + FIFO — 해제하려면 runbook 개입 필요). + - claim 후: `status = IN_FLIGHT`, `attempt_count += 1`, + `next_attempt_at = now + inFlightTimeout`. + - 순서: adapter 는 claim 쿼리에 `ORDER BY occurred_at ASC` 를 쓰는 게 좋고, relay 도 받은 + 배치를 방어적으로 재정렬한다. +- **in-flight timeout 재사용(I6)**: `next_attempt_at` 컬럼을 in-flight 고아 timeout 으로 + 재사용한다. relay 인스턴스가 죽어 `IN_FLIGHT` 로 남은 행이 `next_attempt_at` 을 지나면 다음 + 폴링에서 다시 claim 가능해진다. 별도 `claimed_at` 컬럼 없이 at-least-once 전달을 보장하는 트릭. +- `countByStatus` / `oldestUnpublishedAgeSecondsByEventType` 는 메트릭 게이지 + (`outbox.pending.size`, `outbox.publisher.lag`)의 데이터 소스다. 트랜잭션 밖 read-only + (metric-scrape 경로)로 호출된다. + +### OutboxMessagePublishPort + +- claim 된 outbox 이벤트를 메시지 브로커에 발행하는 outbound 포트. +- **fail-closed 계약(I8)**: 발행 실패는 반드시 `RuntimeException` 으로 표면화해야 한다. 구현은 + 예외를 삼키거나 실패 시 log-and-return 하면 안 된다. 일반적인 fail-open 메시징 publisher(잡고 + 로그 후 정상 반환)와의 **의도적·문서화된 차이** 다 — relay 의 Failure condition 이 발행 실패를 + 예외로 관측해야 FAILED/DEAD 전이 + typed failure report를 구동할 수 있기 때문. 삼킨 실패 + (예외 없음·전이 없음·report 없음)가 + 금지 조건이다 — 행이 영원히 `IN_FLIGHT` 로 남고, aggregate FIFO 큐가 조용히 막히며, 메트릭엔 + 이상이 안 보인다. +- **호출 위치**: relay 유스케이스가 **트랜잭션 밖에서** 호출한다. 짧은 `inWrite` 로 배치 claim → + 트랜잭션 해제 → 발행 → 결과별로 다시 짧은 `inWrite` 로 상태 갱신. 브로커 호출이 진행되는 동안 + 트랜잭션 보유 시간을 최소화한다. + +### PublishPendingOutboxEventsUseCase (릴레이 본체) + +- pending outbox 이벤트를 claim 해 브로커에 발행하는 relay 유스케이스. +- **알고리즘(claim short, publish outside tx)**: + 1. 짧은 write 트랜잭션 안에서 배치를 claim 한다. + 2. `occurred_at` 오름차순으로 방어적 정렬(claim 쿼리도 정렬하지만, adapter 가 안 해도 relay 가 + FIFO 를 강제한다). + 3. 각 이벤트를 **트랜잭션 밖에서** 발행하고 결과로 상태 머신을 구동한다: + - 발행 성공 → `inWrite { markPublished }` → `PUBLISHED`. + - 발행 실패(`RuntimeException`): `attemptCount >= maxAttempts` 면 `markDead`, 아니면 + `markFailed(nextAttemptAt)`를 먼저 성공시킨 뒤 해당 typed failure report를 보낸다. +- **발행 실패는 절대 삼키지 않는다**: relay 는 각 발행 예외를 잡아 FAILED/DEAD 상태 머신을 + 구동하고, 성공한 전이만 `OutboxRelayFailureReportPort`로 보고한 뒤 rethrow 하지 않는다 + (스케줄러 루프가 다음 이벤트로 계속 가야 하므로). 상태 전이가 실패하면 예외가 전파되고 report는 + 없다. reporter가 `RuntimeException`을 던져도 persisted outcome을 바꾸거나 다음 이벤트를 막지 + 못한다. +- **안전한 allowlist report**: `OutboxRelayFailureReport`는 + `code/eventId/eventType/aggregateId/correlationId/attemptCount/nextAttemptAt/cause`만 가진다. + payload, idempotency key, whole `OutboxEvent`, severity/template, arbitrary map은 타입 수준에서 + 전달할 수 없다. retry factory는 `OUTBOX_PUBLISH_FAILED`와 필수 `nextAttemptAt`, dead factory는 + `OUTBOX_DEAD_LETTER`와 null retry time을 고정한다. +- **상태 갱신 실패는 시끄럽게 전파한다**: 발행 성공 후의 `markPublished` 실패는 store/인프라 + 에러지 발행 실패가 아니다. 따라서 FAILED/DEAD 머신을 구동하면 안 된다(이미 전달된 이벤트를 + dead-letter 하는 꼴). 대신 스케줄러 catch 블록으로 전파되고, 행은 `IN_FLIGHT` 로 남아 고아 + visibility-timeout 재claim 경로로 복구된다 → 재발행 → consumer dedupe 가 중복을 + 흡수(at-least-once). 배치 중간의 상태 갱신 실패가 그 tick 의 남은 배치를 중단시키는 것은 + 허용된다 — DB 가 실패 중이면 뒤따르는 갱신도 실패할 테고, 다음 tick 이 모든 `IN_FLIGHT` 고아를 + 재시도하기 때문. +- **수동 와이어링(@Service 아님, context 빈 아님)**: `app-bootstrap` 이 수동으로 생성한다 + (`batchSize`·`inFlightTimeout` 같은 설정값이 필요해서 자동 등록이 안 된다). `UseCaseCapability` + 는 빈 등록 방식과 무관하게 필수다(ArchUnit 강제). 그리고 **Spring 빈으로 등록하면 안 된다**: + 클래스 레벨 `@RequiresPermission` pointcut(web `MethodSecurityConfig`)이 이 타입 빈을 CGLIB + 프록시하려 드는데, `final` 클래스라 불가능하고, 스케줄러 스레드엔 `Authentication` 이 없어 매 + relay tick 이 fail-closed 거부될 것이다. +- **권한**: `"outbox:relay"` 는 시스템 내부 권한이다. relay 는 엔드유저가

OutboxBackoffPolicy + +- relay 재시도 스케줄링용 exponential-backoff-with-full-jitter 정책(I10). +- 공식: `base = 30s`, `maxAttempts = 3`, `delay = base × 2^(attemptCount-1) + jitter(0..base)`, + `nextAttemptAt =

registry·runbook + 업데이트와 **함께만** 바꾼다. +- 지수 계산은 overflow 방지를 위해 `2^30` 에서 cap 한다(`2^30 × 30s > 30년` 이라 안전). + +### outbox 값/상태 타입 (Status · Event · NewOutboxEvent · RelayResult · Command) + +- `OutboxEventStatus` — 행 상태 머신(D5). `PENDING → IN_FLIGHT → {PUBLISHED | FAILED | DEAD}`, + `FAILED → IN_FLIGHT`(재claim), `IN_FLIGHT 고아 → IN_FLIGHT`(I6). `DEAD` 는 FIFO 형제를 막는다 — + 같은 aggregate 의 뒤 행

+- `NewOutboxEvent` — caller 의 write 트랜잭션 안에서 append 할 새 이벤트 값 객체. 모든 필드가 + 필수이고 null/blank 면 생성 시점에 거부한다(D12). caller 가 `eventId`·`idempotencyKey` 를 + 공급한다(I12 — outbox core 는 ID 생성에 비의존). 권장 기본값은 `idempotencyKey = eventId` + (per-event dedup, CloudEvents-C2). +- `OutboxRelayResult` — relay 한 사이클의 결과. `claimedCount` + per-event outcome 목록. 내부 + `Outcome` enum 이 `OutboxEventStatus` 의 5값을 재사용하지 않고 3값(PUBLISHED/FAILED/DEAD)을 + 따로 두는 이유: relay 관점은 "이번 실행에서 무슨 일이 있었나" 이지 "행의 현재 영속 상태" 가 + 아니다(후자는 store 가 5값으로 추적). 별도 enum 이 메트릭·스케줄러 로깅 consumer 에게 relay API + 를 깔끔하게 유지해 준다. +- `PublishPendingOutboxEventsCommand` — relay 커맨드 마커. 스케줄러 구동이라 caller 파라미터가 + 없고, 모든 운영 파라미터는 생성 시점에 주입된다(IdempotencyExecutor 선례). 호출마다 새 인스턴스를 + 만들 필요가 없게 `INSTANCE` 싱글톤을 제공한다. +- `OutboxRelayFailureReportPort` / `OutboxRelayFailureReport` — confirmed FAILED/DEAD 상태를 + adapter에 전달하는 framework-free outbound contract. 구조화 ERROR 필드와 runbook 렌더링은 + messaging adapter가 소유한다. + +### Immutable outbox/polling delivery V2 + +`outbox.v2`는 domain event intent와 delivery state를 분리한다. + +- `NewOutboxEventV2`의 aggregate version과 deterministic ordinal이 ordering authority다. +- `OutboxAppendPortV2`는 caller의 primary write transaction에 참여하고 publication epoch와 + authority를 DB control row에서 얻는다. +- immutable event ID 충돌과 aggregate ordering tuple 충돌은 서로 다른 outcome이다. +- `OutboxPollingDeliveryPortV2`는 publish 밖의 짧은 claim/completion transaction만 소유하고 + owner/token/attempt/version/epoch CAS로 stale relay를 거절한다. +- broker publish와 DB completion 사이 ACK 유실은 stable event ID의

+ +application 계층은 락 획득/해제 계약만 알고, 실제 구현은 adapter 가 소유한다. + +### DistributedLockPort + +- 분산 락 획득 outbound 포트. +- **왜 이 포트가 있나(D2)**: 유스케이스는 락 클라이언트·Spring `LockRegistry`·advisory-lock SQL + 을 직접

`leaseTtl` 은 JVM 이 `close()` 전에 죽어도 + adapter 가 락을 유지하는 최대 시간으로, 죽은 보유자가 시스템을 무한 데드락 시키는 것을 + 막는다. `JdbcLockRegistry` 는 registry 기본 TTL 과 호출별 lock TTL 을 강제하고, in-process + `DefaultLockRegistry` 는 advisory(강제 없음)다. +- **트랜잭션 커밋 순서 불변식(D4)**: 반환된 핸들은 보호 작업의 DB 트랜잭션이 **커밋된 후에만** + 해제해야 한다. 트랜잭션 안(커밋 전)에서 해제하면 lost-update 경합이 생긴다 — 두 번째 스레드가 + 락을 얻어, 첫 트랜잭션의 쓰기가 DB 에 보이기 전에 자신의 read-modify-write 를 시작한다. + - 올바른 패턴: `tryAcquire` → `try { txPort.inWrite(...) } finally { lock.close() }`(커밋 후 해제). + - 금지된 역순: `inWrite` 콜백 안에서 `lock.close()`(커밋 전 해제 → 다른 스레드가 stale 상태를 본다). +- **효율 락이지 정합성 락이
