Object Storage Batch B Checkpoint

Date: 2026-07-28
Branch: codex/objectstorage-production-capability
Worktree: /home/donghyeon/workspace/clean-architecture-backend-template-objectstorage
Evidence grade: repository-local non-skipping unit/contract/application-context tests
Advanced cards: local managed single upload R1, local managed download R1
R2 or production-provider readiness advanced: no

Implemented scope

Added deterministic data/control namespaces, opaque reference/handle codecs, canonical request fingerprints, frozen binding/policy revisions, and bounded operation epochs.
Added six strict canonical JSON control-record families with fixed field order, outer SHA-256 envelopes, schema/size checks, corruption rejection, and checked-in golden digests.
Added provider-neutral publication, scan, reference, direct-session, multipart, and pending-effect state transitions with same-operation replay and conflicting-intent rejection.
Added a provider contract and filesystem-local-dev implementation with bounded streaming, immutable exclusive create, SHA-256 verification, exact inspect/version, full/range transfer, conditional retirement, create resolution, restrictive permissions, and path/symlink confinement.
Added single-process exact-version control CAS and restart/corruption/fault characterization. Logical control keys use .record physical leaves locally so object-store-valid prefix/leaf key pairs cannot collide as filesystem file/directory paths.
Added constructor-bound app.object-storage settings and compile-before-construction provider/destination/route/policy binding. The capability is disabled by default and filesystem-local-dev is rejected for prod/production.
Added disabled, unselected, invalid, selected-success, selected-construction-failure, close, legacy-only, and namespace-separated dual-run composition tests.
Added semantic routing evidence for publish, replay without producer invocation, inspect, full transfer, absent reference, and exact retained route lookup.
Added the exact nine-card readiness registry. Only local managed single upload/download are R1; direct, multipart, quarantine, retention, and production reconciliation remain R0.

TDD and defect evidence

Planned RED checks failed for the intentionally absent codec/kernel/provider/settings/readiness types before each implementation. Additional tests found and drove these corrections:

Local control keys may legally have both a leaf and a child in object storage, while a filesystem cannot have both reference and reference/lifecycle; local physical .record mapping fixed the collision without changing logical keys.
ObjectInspectionPort.inspect initially threw for an absent known-route reference; it now returns Optional.empty() while incomplete/corrupt evidence still fails closed.
The application purity test initially scanned its own test output after a full check; it now derives the production class root from a production contract type.
The general B7 ArchUnit rule initially classified objectstorage provider-internal SPI/control return values as public adapter responses. The existing negative fixture remains active, while a dedicated non-empty rule now checks the actual objectstorage *Adapter semantic boundaries.

No skipped Docker or external-service test is used as Batch B readiness evidence.

GREEN verification

All commands ran from src/ unless noted and completed with BUILD SUCCESSFUL after the documented RED/fix cycles:

./gradlew :adapter:outbound:objectstorage:verifyDependencyLocks --console=plain
./gradlew :adapter:outbound:objectstorage:test \
  --tests '*ObjectNamespaceCodecTest' \
  --tests '*ObjectRequestFingerprintCodecTest' \
  --tests '*ObjectOperationEpochTest' --console=plain
./gradlew :adapter:outbound:objectstorage:test \
  --tests '*ObjectControlRecordCodecTest' \
  --tests '*ObjectOperationStateMachineTest' \
  --tests '*ObjectOperationKernelTest' --console=plain
./gradlew :adapter:outbound:objectstorage:test \
  --tests '*ObjectStorageProviderContract' \
  --tests '*LocalDevObjectStorageProviderTest' \
  --tests '*LocalDevObjectStorageRecoveryTest' --console=plain
./gradlew :adapter:outbound:objectstorage:test \
  --tests '*ObjectStorageBindingCompilerTest' \
  --tests '*ObjectStorageCapabilityConfigTest' \
  --tests '*RoutingObjectStorageAdapterTest' --console=plain
./gradlew :adapter:outbound:objectstorage:test \
  --tests '*ObjectStorageReadinessRegistryTest' --console=plain
./gradlew :sample-portfolio:test --console=plain
./gradlew :application-core:check \
  :adapter:outbound:objectstorage:check --console=plain
./gradlew :app-bootstrap:test --tests '*CleanArchitectureTest' --console=plain
./gradlew verifyCleanArchitectureDependencies --console=plain

The final combined application/objectstorage checkpoint completed in 23 seconds. The focused Clean Architecture suite and dependency verification also passed.

LLM Wiki capture

The canonical vault required by repository policy, /home/donghyeon/workspace/ai-tool/llm-wiki-private/, and its parent /home/donghyeon/workspace/ai-tool/ do not exist in this environment. Therefore the required raw/branch-notes/codex-objectstorage-production-capability.md and any derived raw documents could not be created or updated. No similarly named non-canonical clone was used. This exact access block is recorded in the plan/design status and at this Batch B boundary.

Remaining gates and risks

filesystem-local-dev has no multi-node linearizability or power-loss durability evidence and is forbidden in production profiles.
The canonical S3/MinIO provider contribution, async bounded transport, provider qualification, response-loss fault tests, and protected AWS evidence are not implemented.
Direct grants, multipart, quarantine/scan, retention/legal hold, privileged purge, reapers, and production reconciliation remain R0.
The sample Poster workflow still uses the deprecated whole-byte[] port and transaction-coupled legacy choreography. It is explicitly activated only in sample local/test configuration.
External API/broker consumers and deployed legacy data remain uninspected, so Gate A still blocks destructive migration or legacy removal.
