# Object Storage Batch A Checkpoint

- Date: 2026-07-28
- Branch: `codex/objectstorage-production-capability`
- Worktree:
  `/home/donghyeon/workspace/clean-architecture-backend-template-objectstorage`
- Claimed level: R0 application contract only
- Provider readiness advanced: no

## Implemented scope

- Characterized the legacy caller-key overwrite, whole-object materialization, locator exposure,
  eager filesystem directory creation, optional S3 bucket provisioning, and Poster transaction/API
  coupling without changing those behaviors.
- Added provider-neutral identities, opaque checked references/handles, bounded streaming
  callbacks, content identity, digest/range values, requests, receipts, outcomes, and narrow ports
  under `dev.caskeleton.application.objectstorage`.
- Required an `ObjectOperationKey` on mutation requests and separated normal publication,
  scan-maintenance, purge-maintenance, direct, and staged privilege surfaces.
- Added recursive contract-purity tests and an ArchUnit freeze for the one existing sample legacy
  import.
- Marked the legacy `ObjectStoragePort` and `StoredObject` as removal boundaries without adapting
  new semantic calls back to raw keys.

No provider-neutral kernel, canonical namespace/control codec, local R1 provider, S3/MinIO
qualification, sample migration, or R2 readiness claim is included.

## TDD evidence

The planned RED checks failed only for the intentionally missing types or removal annotations:

- `ObjectStorageIdentityContractTest`: missing identity types before Task 2 implementation.
- `ObjectContentContractTest` and `ObjectStorageValueContractTest`: missing content/value types
  before Task 3 implementation.
- `ObjectStoragePortContractTest`: missing request/receipt/port family before Task 4 implementation.
- `ObjectStorageArchitectureContractTest`: missing legacy removal annotations before Task 5
  implementation.

An initial ArchUnit DSL compilation error was a test-authoring error, not accepted as a RED result;
the rule was corrected and rerun.

## GREEN verification

All commands ran from `src/` and completed with `BUILD SUCCESSFUL`:

```bash
./gradlew :application-core:resolveAndLockAll --write-locks
./gradlew :application-core:verifyDependencyLocks --console=plain
./gradlew :application-core:test --tests '*ObjectStorageIdentityContractTest' --console=plain
./gradlew :application-core:test \
  --tests '*ObjectContentContractTest' \
  --tests '*ObjectStorageValueContractTest' --console=plain
./gradlew :application-core:test --tests '*ObjectStoragePortContractTest' --console=plain
./gradlew :application-core:test \
  --tests '*ObjectStorageArchitectureContractTest' --console=plain
./gradlew :app-bootstrap:test --tests '*CleanArchitectureTest' --console=plain
./gradlew :application-core:check --console=plain
./gradlew verifyCleanArchitectureDependencies --console=plain
./gradlew :adapter:outbound:objectstorage:test :sample-portfolio:test --console=plain
```

The final combined legacy focused suites completed in 27 seconds. Deprecation-for-removal warnings
are expected evidence that legacy consumers remain visible; they are not suppressed.

## 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` could not be created or updated.
No similarly named non-canonical clone was used. This exact access block is recorded in both the
plan and design headers and here at the Batch A boundary.

## Remaining gates and risks

- External broker and REST consumers and deployed legacy data were not inspected; Gate A remains
  blocked for legacy removal or public API versioning.
- The new contracts have no provider implementation yet.
- The current legacy adapter retains whole-object and raw-locator behavior by design until the
  later migration batch.
- No readiness registry row is promoted by this checkpoint.
