Added in +`V2__fileserver_recovery_and_staging_cleanup.sql` with one open item per file, so repeated sweeps +update a worklist rather than accumulating a log. + +Pinned by `PostgreSqlFileserverReclamationIntegrationTest`. + +### 7. `fs_cleanup_item.upload_id` + +A staging object is addressed by upload, not by file. Without this column a queued staging cleanup +could name only already-published content, so a cancelled or expired upload left bytes nothing could +find. Added in the same migration, with a check constraint that an item names exactly one target. + +Pinned by `PostgreSqlFileserverReclamationIntegrationTest`. + +### 8. `ContentReferenceLedger` and `StagingUploadLocator` + +The orphan scan must ask whether a record still claims a physical object, and reconciliation must +map a file back to the upload that last staged it. Neither question is answerable through the +design's `FileMetadataStore` or `UploadSessionStore` as written. Rather than widen those +design-fixed interfaces, both are narrow single-method ports. + +Pinned by `PostgreSqlFileserverReclamationIntegrationTest` and `LocalOrphanScanAdapterTest`. + +## Interpretations + +### 9. 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;

Backoff is exponential with full or +decorrelated jitter, bounded by `max-backoff`, by `Retry-After`, and by the remaining deadline. No +connection and no bulkhead permit is held while a backoff is waiting. diff --git a/docs/httpclient/security.md b/docs/httpclient/security.md new file mode 100644 index 0000000..e15f28c --- /dev/null +++ b/docs/httpclient/security.md @@ -0,0 +1,75 @@ +# HTTP Client Platform — Security Guide + +## What the platform owns + +`Authorization`, `Proxy-Authorization`, `Host`, `Content-Length`, `Transfer-Encoding`, +`Traceparent`, `Tracestate`, `Baggage`, and (unless a profile opts in) `Cookie` are platform-owned. +A caller cannot set them. `Idempotency-Key` is accepted only when the operation declares it.

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*.

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.

NetworkNT 3.0.2 now +validates the canonical schema against its bundled Draft 2020-12 meta-schema and validates the +exact six closed manifests under strict parsing/configuration. Mutation coverage exercises +additional properties, type, required, enum, minimum/maximum, pattern, duplicate JSON keys, and +an independent cross-resource duplicate-program-id Java invariant. The first GREEN attempt exposed +that the canonical ACL pattern rejected the existing `SCRIPT|LOAD` command form; the pattern was +narrowly relaxed before independent review identified that it also admitted dangerous commands. +A second RED run failed exactly two tests because the schema had no exact allowlist and accepted +`FLUSHALL`, `CONFIG|SET`, and `MODULE|LOAD`. 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. Review coverage also rejects a trailing manifest +JSON token and a duplicate schema key on the compile path, and pins invalid meta-schema diagnostics +to `/type:type`. Final verification passed: +`./gradlew :adapter:outbound:cache-redis:test --tests '*RedisProgramManifestContractTest' --console=plain` +(12 tests), `./gradlew :adapter:outbound:cache-redis:test +:adapter:outbound:cache-redis:spotlessJavaCheck --console=plain`, +`./gradlew :adapter:outbound:cache-redis:verifyDependencyLocks +:adapter:outbound:cache-redis:spotlessCheck --console=plain`, and +`./gradlew :adapter:outbound:cache-redis:check --console=plain`.

The checks + exercise the mechanically enforceable catalog/containment rules; the three semantic migrations + above remain explicitly blocked on project-owner evidence. + +### Batch 5-A evidence — exact tracked registry catalog (2026-08-02) + +The owner catalog now enumerates exactly eight regular, non-symlink direct children: seven +universal contract registries plus the specialized object-storage readiness registry. The initial +focused RED failed compilation on the deliberately absent `RegistryGovernanceCatalog` (13 symbol +errors). A second exact-version mutation RED proved that numeric coercion admitted +`schema_version: 1.5`; the implementation now requires the integer value `1`. Strict SnakeYAML +safe construction disables duplicate keys and aliases, enforces exact root keys, a non-empty list +of map rows, non-blank unique identities, the existing universal row policy, and the specialized +owner delegation/provenance policy. Missing, unknown, non-regular, symlinked, malformed, duplicate, +false-provenance, block-scalar spoofing, reordered-header, and fabricated-branch-header fixtures +fail closed. + +Gradle declares `docs/registries` as a relative-path-sensitive `:app-bootstrap:test` directory +input. The object-storage owner declares its canonical readiness YAML as a relative-path-sensitive +file input and passes its absolute path through `objectstorage.readiness.registry`; its leaf test no +longer searches parent directories.

The Java set is now named `LEGACY_STUB_DEBT`, contains exactly the 43 current +`status: stub` runbooks, and is checked bidirectionally against canonical tracked runbook files. +The stale `migration-failed.md` entry was removed because that runbook is already active. 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. The seven universal registries contain 324 +non-reference `required_test` occurrences and 216 unique IDs. 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. Placeholder owners, issues, selectors, and +sunsets were not added to make the checks pass. + +## Batch 6 — bounded P2 cleanup + +- [x] Extend link-check triggers and scan scope to module README/CLAUDE documents. +- [x] Make Poster migration gate labels version-neutral while preserving externally stable job IDs. +- [x] Replace fixed HTTP timeout sleeps with deterministic latch-controlled handlers. +- [x] Separate sample-off compile evidence from its minimal runtime proof if exact required tests can + be established without weakening coverage. +- [x] Run focused docs, CI, HTTP client, sample-off, and wrapper checks. + +Batch 6 link/Poster evidence: test-first changes made the two focused app-bootstrap contracts fail +only for the absent module documentation scope and the legacy Poster V7 internal gate ID. The same +contracts then passed with exact pull/push/lychee scope, all 27 gate IDs, and the stable external +`poster-image-v7-migration` workflow job plus `posterImageMigrationTest` task mapping. 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 `.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`.

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`.

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` carries exactly one payload codec and `StreamRecord` +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` — 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-`) 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/specs/2026-08-01-release-hygiene-refactoring-design.md b/docs/superpowers/specs/2026-08-01-release-hygiene-refactoring-design.md new file mode 100644 index 0000000..3b564a4 --- /dev/null +++ b/docs/superpowers/specs/2026-08-01-release-hygiene-refactoring-design.md @@ -0,0 +1,160 @@ +# Release Hygiene Refactoring Design + +**Date:** 2026-08-01 +**Status:** approved by the user's instruction to apply the preceding review +**Scope:** release-blocking architecture test, Gradle wrapper supply-chain integrity, Docker build configuration inputs, SpotBugs analysis completeness, and the observed Gradle 10 deprecation + +## Context + +The repository-wide review found that the 19-leaf Clean Architecture dependency model is healthy, +but the release surface is not green: + +- `:app-bootstrap:sampleOffTest` fails because a whole-composition Object Storage ArchUnit rule is + evaluated on the intentionally sample-free classpath with `allowEmptyShould(false)`. +- the two Dockerfiles run Gradle before copying configuration-time registry inputs, while the root + build also requires a Git checkout during configuration even though the Docker context excludes + `.git`; +- `gradle-wrapper.properties` selects Gradle 9.0.0 while the checked-in wrapper JAR is from another + official Gradle release, and the distribution checksum is absent; +- clean SpotBugs analysis reports missing Spring Session, Micrometer Context Propagation, and + protobuf classes; +- a root task calls `Task.project` during execution, which is deprecated and scheduled to fail in + Gradle 10. + +This design deliberately closes those release-hygiene defects before changing idempotency, outbox, +security, or sample data behavior.

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.

Ordinary `redisCompositionTest` excludes the tag. A new explicit +`redisSessionHttpIntegrationTest` task includes only that tag, fails on no discovery or any skip, +always reruns, pins UTC, and passes the checked-in Redis image registry path. + +The task is deliberately not attached to ordinary local `check`, because it requires Docker. It is +added to the existing release-blocking `redis-standalone` CI job, which is the Docker-capable Redis +lane. Docker availability and container startup are attempted directly; no condition, assumption, +or environment flag may convert absence into a skip. + +The test loads `redis.approved.image` from `src/gradle/redis-test-images.properties` and rejects an +unpinned reference. It creates an ephemeral CA/server certificate and a named, least-privilege ACL +user, then connects with TLS, full hostname verification, and explicit CA trust.

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.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` 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[]` 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. Do not redirect +to `/dev/null` and do not silence the Gradle `Exec` task globally. + +#### Mockito/CDS + +Provide `mockito-core` to test JVMs as an explicit startup `-javaagent` through a relocatable Gradle +argument provider. This removes reliance on Java 21+ runtime self-attachment. Add test-JVM-only +`-Xshare:off` because Mockito's bootstrap append otherwise prints the harmless CDS warning. No +production JVM argument changes. + +#### Skips + +Retain exactly these five intentional app-bootstrap contract skips: + +- `emailNotificationAdapterRunsOnlyWhenConfigured()`; +- `slackNotificationAdapterRunsOnlyWhenConfigured()`; +- `redisCacheAdapterRunsOnlyWhenEnabled()`; +- `messagingBrokerAdapterRunsOnlyWhenConfigured()`; +- `DisabledOptionalAdapterFixture.wouldFailIfItEverRan()`. + +Qualification tasks continue to require positive discovery, at least one executed test, zero skips, +and fresh XML, so this policy cannot turn a selected qualification lane green without execution. +Any additional skip, or any of these five moving outside its named optional-adapter contract, fails +the inventory check. + +### 6. Warning-zero enforcement + +After all existing warnings are removed: + +- configure every leaf `JavaCompile` task with `-Werror`, `-Xlint:deprecation`, and + `-Xlint:unchecked` in the root build policy; +- retain Error Prone on the same compile tasks so its warnings are promoted by `-Werror`; +- remove the root `checkstyleTest`/`spotbugsTest` warning-only policy and the app-bootstrap + `sampleOffTest`, `functionalTest`, and `conditionalTransportTest` Checkstyle/SpotBugs + `ignoreFailures` overrides, making every such task included by `check` blocking; +- retain exact suppression comments as the only approved exception mechanism; +- run Gradle with `--warning-mode=fail` in the warning-clean CI lane so Gradle API deprecations also + fail rather than print. + +`quarantineTest` remains non-blocking by design. Protected AWS/Docker qualifications remain separate +environment evidence and are not converted into local unit tests. + +## File Ownership and Expected Change Groups + +### Root build policy + +- `src/build.gradle` +- `src/gradle/test-jvm-agents.gradle`, defining the relocatable Mockito `-javaagent` argument + provider and test-only `-Xshare:off` policy, applied once by the root build +- `.github/workflows/ci-quality-gates.yml`, adding `--warning-mode=fail` to the blocking + `quality-gates` Gradle invocation + +### Production leaves + +- `src/application-core` +- `src/adapter/inbound/web` +- `src/adapter/outbound/cache-redis` +- `src/adapter/outbound/fileserver` +- `src/adapter/outbound/httpclient` +- `src/adapter/outbound/identifier` +- `src/adapter/outbound/messaging` +- `src/adapter/outbound/notification` +- `src/adapter/outbound/objectstorage` +- `src/adapter/outbound/persistence-jpa` +- `src/app-bootstrap` +- `src/sample-portfolio` +- `src/shared-contract` + +Every focused command is derived from the owning leaf's `gradle_path` in +`src/config/architecture/modules.json`; no production dependency edge changes are permitted unless +the registry is deliberately updated and its architecture verifier passes. + +### Tests and shell contract + +- owning leaf tests adjacent to every behavior change +- exact architecture violation fixtures under app-bootstrap test sources +- `infra/redis-lab/test/redis-lab-contract.sh` + +## Implementation Sequence + +1.

It does not yet prove that a real bearer request crosses issuer discovery, JWKS +retrieval, signature/claim validation, principal conversion, `SecurityFilterChain`, and the public +error envelope. CORS configuration is likewise untested at the filter boundary, where preflight +ordering relative to authentication is the important behavior. + +These are release-boundary checks and must not silently skip because an external IdP, environment +variable, or optional flag is absent. + +## Decision + +Add a dedicated `webSecurityBoundaryTest` task that reuses the ordinary test output/classpath and +runs only JUnit tests tagged `security-boundary`. Ordinary `test` excludes that tag so each contract +runs once. The dedicated task: + +- fails when no tests are discovered; +- disables up-to-date reuse; +- fails the root suite when any test reports `SKIPPED`; +- is required by the inbound-web `check` task; +- uses UTC and no environment-dependent conditions or assumptions. + +JWT tests use a JDK loopback `HttpServer` bound to `127.0.0.1` on an ephemeral port. It serves the +minimum OIDC discovery document and JWKS response. Tests generate ephemeral RSA keys and compact +RS256 JWTs with the already-resolved Nimbus dependency; no new library or external network is +allowed. Each failure case uses a fresh server and Spring context to prevent decoder/JWK cache +cross-contamination. + +CORS tests build the production `SecurityConfig` and real `springSecurityFilterChain` with direct +configuration properties. They issue real preflight and actual-origin MockMvc requests. A test JWT +decoder bean is allowed here because CORS ordering—not token decoding—is the owned boundary. + +## JWT/JWKS Contract + +- application context startup performs zero discovery/JWKS calls (lazy decoder); +- a correctly signed token reaches a protected controller and exposes the expected + `AuthenticatedPrincipal` subject/roles; +- expiry beyond the configured 60-second skew, issuer

discovery metadata that is fetched successfully but is internally inconsistent produces the + fixed 500 `INTERNAL_AUTH_MISCONFIGURATION` envelope rather than a raw initialization exception; +-

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:** Spring 기반 Backend Skeleton에 Typed Service Client, Named Client Profile, 증거 기반 Retry, Blocking·Reactive 전송, OAuth2·TLS, Dynamic URL SSRF 방어, Streaming·SSE, 관측성을 제공하는 운영 가능한 외부 HTTP Client 플랫폼을 구현한다. + +**Architecture:** 일반 서비스 코드는 `@HttpExchange` 기반 H1 Typed Client를 사용하고, H2 Generic Gateway와 H3 Dynamic Target Gateway는 별도 권한 경계로 제공한다. 모든 호출은 immutable Named Client Profile에서 transport, pool, timeout, auth, resilience, security, observability 설정을 가져오며, Retry Coordinator가 `OperationIdempotency`, `BodyReplayability`, `ExecutionEvidence`, deadline, retry budget을 근거로 물리 시도를 통제한다. Blocking 경로는 RestClient와 Apache/JDK, Reactive 경로는 WebClient와 Reactor Netty를 사용한다. + +**Tech Stack:** Java 21, Gradle Kotlin DSL, Spring Framework 6.2 common baseline with Spring 7.0 compatibility tests, Spring RestClient, Spring WebClient, Spring HTTP Service Client, Apache HttpClient 5, JDK HttpClient, Reactor Netty, Resilience4j, Spring Security OAuth2 Client, Micrometer, OpenTelemetry, JUnit 5, AssertJ, ArchUnit, MockWebServer, WireMock, Testcontainers, Toxiproxy, BlockHound. + +## Global Constraints + +- 일반 업무 모듈의 기본 진입점은 H1 Typed Service Client다. +- H2 Generic Gateway는 등록된 profile의 scheme, host, port, TLS, credential, hard limit을 변경하지 못한다. +- H3 Dynamic Target Gateway는 Trusted profile의 credential, Cookie, default header를 상속하지 않는다. +- H4 Native engine API는 application-facing public API로 노출하지 않는다. +- 모든 upstream은 고유한 Named Client Profile을 가진다. +- Blocking 기본 전송은 RestClient + Apache HttpClient 5이며 JDK HttpClient는 경량 대안이다. +- Reactive·Streaming 기본 전송은 WebClient + Reactor Netty다. +- HTTP/1.1과 HTTP/2는 Stable, HTTP/3는 Experimental이다. +- RestTemplate은 migration module에서만 사용하고 신규 기능을 추가하지 않는다. +- production에서 Simple request factory를 허용하지 않는다. +- total deadline은 pool acquire, DNS, connect, TLS, request write, response read, retry backoff 전체를 감싼다. +- Retry는 method만으로 결정하지 않고 idempotency, idempotency key, body replayability, execution evidence, deadline, retry budget을 함께 판정한다. +- `NOT_SENT`는 전송되지 않았음을 증명할 수 있을 때만 사용한다. +- 비멱등 `SENT_NO_RESPONSE`는 자동 Retry하지 않고 `HttpAmbiguousExecutionException`으로 반환한다. +- first response byte가 application에 전달된 뒤 transparent Retry를 금지한다. +- Retry backoff 동안 connection과 attempt bulkhead permit을 보유하지 않는다. +- 물리 시도는 Circuit Breaker → Rate Limiter → Bulkhead → HTTP Call 순서를 사용한다. +- OAuth2 token refresh는 동일 cache key에 대해 single-flight다. +- 401 자동 재호출은 최대 한 번이며 replayable하고 안전한 operation에만 적용한다. +- TLS 1.2·1.3과 hostname verification을 강제하고 trust-all과 평문 fallback을 금지한다. +- Dynamic Target는 URI canonicalization, 모든 DNS 결과의 IP 검증, 실제 connection pinning, redirect 재검증을 수행한다. +- metric label에는 전체 URL, query value, path variable, user ID, tenant ID 원문, token, Cookie, idempotency key를 기록하지 않는다. +- Reactive event-loop에서 blocking DNS, file I/O, token load, JSON 변환을 실행하지 않는다. +- 모든 response lifecycle은 성공, 실패, decode error, size 초과, cancel에서 connection·buffer를 정리한다. +- 모든 작업은 실패 테스트 작성 → 실패 확인 → 최소 구현 → 통과 확인 → 커밋 순서로 수행한다. +- 각 Task는 독립 검토 가능한 하나의 커밋으로 종료한다. + +--- + +## 1. 확정 파일 구조 + +```text +backend-skeleton/ +├── settings.gradle.kts +├── build.gradle.kts +├── build-logic/ +│ └──

deadline 이내다. | +| Retry | 모든 추가 attempt가 idempotency·replayability·evidence·deadline·budget으로 설명된다. | +| Ambiguity | 비멱등 `SENT_NO_RESPONSE`가 `HttpAmbiguousExecutionException`으로 구분된다. | +| Resource | 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 +→

{@code min-replicas-to-write} with a bounded {@code min-replicas-max-lag} is what turns that + * into a {@code NOREPLICAS} refusal the caller can act on — the same promotion then lost one + * write instead of 2,086.

It can be waived, because a deployment may genuinely not care about a lost write and this + * SDK does not own the server. Waiving it takes an explicit setting, so the trade is recorded + * rather than discovered during an incident. + * + *

They are not the only writes that need reconciling, and on an unguarded deployment + * they are not even the majority.

What closes that window is on the server: {@code min-replicas-to-write} with a bounded {@code + * min-replicas-max-lag} makes an orphaned primary refuse writes it cannot keep, turning silent loss + * into a {@code NOREPLICAS} refusal that arrives as a definite, non-ambiguous failure.

    Why this test exists

    + * + *

    Every Fileserver layer is already covered against fakes — the application services against + * hand-rolled ports, the local storage platform against a temporary directory, the JPA stores + * against a real database, the web layer against standalone MockMvc. None of that exercises the + * joins. A content key written by the metadata store and read by the download gateway, a digest + * computed while streaming and compared against the persisted column, an ETag minted at publish and + * matched on a conditional request: each of those crosses two modules that were only ever proven + * separately. + * + *

    Why a focused context rather than a full application boot

    + * + *

    Booting {@code CaSkeletonApplication} requires the ~50 {@code ${...}} placeholders {@code + * application.yml} resolves from {@code src/.env}, and puts messaging, cache, and notification + * autoconfiguration on the path of a test that has nothing to say about them. {@code + * spring.config.name} points the environment at a name no configuration file uses, so the context + * is built from the inline properties below and nothing else. What is assembled is production code: + * the real {@link FileserverPlatformAutoConfiguration} and the four configurations it imports. + * + *

    The operator sequence is part of the fixture

    + * + *

    The schema stream is applied and promoted in {@link #runtimeProperties} rather than in a + * {@code @BeforeAll}, because the composition root refuses to start against an unpromoted stream + * and {@code @BeforeAll} runs after the context is refreshed. That ordering constraint is not an + * inconvenience to work around — it is the fail-closed guard doing its job, and this fixture is the + * operator sequence the runbook documents. + */ +@Testcontainers +@SpringBootTest( + classes = FileserverRoundTripContractTest.FileserverRuntime.class, + properties = { + // No configuration file carries this name, so application.yml is never loaded and the + // environment is exactly the list below. + "spring.config.name=fileserver-round-trip", + "spring.main.banner-mode=off", + // Flyway is driven by the operator fixture, one stream at a time, exactly as in production. + "spring.flyway.enabled=false", + "spring.jpa.open-in-view=false", + "spring.jpa.hibernate.ddl-auto=none", + "app.fileserver-platform.enabled=true", + "app.fileserver-platform.instance-id=round-trip-node", + "app.fileserver-platform.security.access-policy=role-based", + // Metrics are a separate concern with their own tests; leaving them off keeps a MeterRegistry + // out of a context that would otherwise need one only to satisfy a bean signature. + "app.fileserver-platform.observability.metrics-enabled=false", + "app.fileserver-platform.observability.fingerprint-key=round-trip-fingerprint", + // The high-water marks are unit-tested against a fake probe.
