src/artifactstore/registry/__init__.py implements the Registry class with six operations the HTTP API and CLI both consume: * create_package(name, producer, subject, retention_class, actor, metadata?) -> UUID. Validates retention_class against the seed table; emits v1.package.created with CBOR payload; applies view in same transaction. * ingest_file(package_id, relative_path, media_type, stream, actor) -> UUID. Validates the package is in 'created' status and rejects duplicate relative_path. Calls dataplane.ingest_stream (which dual-hashes and writes to the backend). Emits v1.file.ingested whose payload carries the file metadata + storage receipt + deterministic storage_location_id so replay reproduces UUIDs. View handler in events/views.py inserts artifact_files + storage_locations and bumps last_event_sequence on the package. * finalize_package(package_id, actor) -> ContentAddress. Queries the views to build a Manifest dataclass, encodes it as canonical CBOR, computes the BLAKE3 content address, and writes v1.package.finalized whose payload IS the canonical CBOR manifest. The view handler now records manifest_digest = event.payload_digest (BLAKE3 of the manifest), not a separate field parsed from the payload. * get_manifest_bytes(package_id, format='cbor'|'json') -> bytes. Reads the finalize event payload (CBOR) and optionally projects to JCS. * get_file(file_id) -> AsyncIterator[bytes]. Looks up the storage location and serves bytes via the data plane. * tail_events(since_sequence, poll_interval_seconds) -> AsyncIterator[Event]. Pass-through to events.tail. src/artifactstore/events/views.py: - New v1.file.ingested handler. - v1.package.finalized handler updated: manifest_digest now derived from event.payload_digest (= BLAKE3 of the canonical CBOR manifest payload). - All inserts now pass created_at=event.created_at explicitly so replay produces byte-identical materialised state (server_default=now() was firing fresh on each replay insert). tests/integration/test_registry.py (7 cases): - Rejects unknown retention class. - create_package writes the event and the package row. - ingest_file writes file + storage_location, populates content_address with blake3 prefix. - Duplicate relative_path raises DuplicateRelativePathError. - ingest into unknown package raises PackageNotFoundError. - Finalising twice raises IllegalPackageStateError. - End-to-end: create + ingest 3 files + finalize + read manifest in CBOR and JSON + download each file with byte equality + tail 5 events + replay + assert byte-identical materialised state across pre and post snapshots. tests/integration/test_event_log.py updated: the v1.package.finalized replay test now uses the new payload semantics (payload is the canonical CBOR manifest; manifest_digest = BLAKE3 of payload). Gates: ruff clean, mypy --strict clean on 45 files, 77 tests pass. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
