There was a problem hiding this comment.
When a new writer replaces an existing blob, os.Rename has already overwritten the committed file before directory synchronization runs. If that synchronization fails, this cleanup removes w.target, which is now the replacement file; the previous value cannot be recovered. The commit reports an error, but a previously stored audit-media blob has been irreversibly lost.
Artifacts
Deterministic replacement and directory-sync failure repro test
- Temporary Go test used to replace an existing blob and inject the post-rename directory sync failure; it directly exercises the reported loss condition.
Baseline successful blob replacement output
- Captured command output shows a normal replacement commit succeeds and key k contains new, establishing the replacement contract.
Injected post-rename directory-sync failure output
- Captured command output shows Commit returns the injected directory-sync error and Open(k) returns blob not found, proving the old blob is lost.
Full blobstore test suite output with repro test
- Captured full internal blobstore suite output shows all existing tests and both behavioral repro tests pass, confirming the narrow check ran in the package suite.

Part of #1065. Adds media storage (ADR-0013) and moves audit-logged audio and images out of the database.
What changes for users
LOGGING_LOG_AUDIO_BODIES/LOGGING_LOG_IMAGE_BODIESare written to media storage instead of being base64-encoded into the audit document. The 8 MB audio cap, the per-entry image budget and thetoo_largeplaceholder are gone; a streamed speech response is stored whole as it is relayed.MEDIA_STORAGE_TYPE(filesystem, default, ormemory) andMEDIA_STORAGE_PATH(defaultdata/media, same rule as the SQLite path). Startup warns when media logging is on and the path is on an ephemeral container filesystem.LOGGING_RETENTION_DAYS) via an hourly sweep. Rows written before this change keep their inline base64 and still render in the dashboard.GET /admin/media/{id}streams a stored object with range support, scoped by user path like/admin/audit/detail. The dashboard fetches media with the bearer token and plays it from an object URL.Design
internal/blobstore:filesystemandmemorybackends behind a four-method interface; keys are validated, writes are temp-file plus rename.internal/mediastore:media_objectsrecords (SQLite, PostgreSQL, MongoDB, memory) paired with a blob store; blobs are laid out as<kind>/<yyyy>/<mm>/<dd>/<id>.<ext>so a mounted volume is browsable.file_mappingsstays the public Files API index;media_objectsis the storage ledger. Audit media never appears in/v1/files./v1/videosbuilding on the same service.Also skips the gitignored
.claudedirectory in the test-conventions scan.Summary by CodeRabbit
