Object Storage Phase 0 Inventory

• Captured: 2026-07-28
• Branch: codex/objectstorage-production-capability
• Scope: repository-local source, tests, configuration, migrations, and documentation
• Evidence grade: repository-local only; deployed data, broker subscribers, and external REST consumers were not inspected

Commands

rg -n 'application\.storage|ObjectStoragePort|StoredObject|ca-skeleton\.objectstorage|file://|s3://' \
  src docs
rg -n 'image_key|posters/.*/image' src/sample-portfolio
rg -n 'poster\.image-attached|StoredObjectResponse|PosterResponse|imageKey' \
  src/sample-portfolio docs

The commands completed successfully in the isolated worktree. Results are classified below. Documentation hits in the Object Storage design/plan describe the migration and are not runtime consumers. The s3://bucket/key-1 fixture in IdempotencyStoreAdapterTest belongs to the generic idempotency response-reference test and is not an Object Storage legacy-port consumer.

Repository-local runtime inventory

Contract/data	Producer	Repository-local consumers	Classification
ObjectStoragePort / StoredObject	application-core/application/storage	filesystem and S3 adapters, UploadPosterImageUseCase, PosterController/PosterWebMapper	legacy runtime contract
ca-skeleton.objectstorage.*	ObjectStorageSettings / ObjectStorageConfig	sample runtime through its objectstorage runtime dependency	legacy runtime configuration
file:// receipt	FilesystemObjectStorageAdapter	StoredObjectResponse.location through PosterWebMapper	public legacy locator
s3://bucket/key receipt	S3ObjectStorageAdapter	StoredObjectResponse.location through PosterWebMapper	public legacy locator
/posters/{id}/image	PosterController	repository tests and the generated/public HTTP contract	legacy inbound API
StoredObjectResponse	PosterController / PosterWebMapper	HTTP caller, with key, size, contentType, and location	legacy response DTO
PosterResponse.imageKey	PosterWebMapper	list/get/create/update/publish/archive HTTP responses	legacy general response field
poster.image-attached	PosterEventPublisher	no subscriber found in this repository	versionless broker event; external consumers unknown
poster.image-attached.imageKey	PosterImageAttached and publisher JSON	no subscriber found in this repository	raw locator-shaped event field
poster.image_key	Flyway V6, PosterEntity, persistence mapper	Poster aggregate and repository adapter	stored-data schema
posters/{id}/image key	UploadPosterImageUseCase	aggregate imageKey, event payload, DB row, HTTP response	deterministic overwriteable legacy key

Executable characterization

The following tests pin the current behavior without approving it as the target design:

• LegacyObjectStorageBehaviorTest
  • caller-selected keys overwrite;
  • get returns Optional<byte[]> and materializes the whole object;
  • receipts expose file:// and s3:// locators.
• LegacyObjectStorageConfigTest
  • missing backend configuration selects filesystem;
  • context creation creates the filesystem directory before the first write;
  • autoCreateBucket=true probes and creates a missing bucket during S3 bean construction.
• LegacyPosterImageUploadCharacterizationTest
  • remote storage is called while TransactionPort.inWrite is active;
  • the controller calls MultipartFile.getBytes;
  • the response exposes raw key and provider location;
  • Poster deletion leaves the legacy object untouched.

External inventory gap and Gate A

Repository search does not prove that the following have no deployed consumers:

• POST /posters/{id}/image;
• StoredObjectResponse.key and .location;
• PosterResponse.imageKey;
• broker event type poster.image-attached and its imageKey payload;
• rows already stored in poster.image_key;
• filesystem/S3 objects already written under posters/{id}/image.

No deployed database, object namespace, access log, API client catalog, broker consumer group, schema registry, or owning team approval was inspected. Therefore removal, in-place field rename, event payload replacement, or legacy-object deletion remains blocked. Approval Gate A must obtain owner and consumer evidence and choose an additive/versioned migration contract.
