WP-0001-T010: manifest model, canonical CBOR codec, JCS projection
Adds the manifest layer per ADR-0003. The canonical wire format is CBOR with
deterministic encoding (cbor2 canonical=True: definite-length, shortest-form
integers, sorted map keys); JCS (RFC 8785) is the JSON projection.
src/artifactstore/manifest/:
- model.py: frozen dataclasses for Manifest (manifest_version=1, package,
files, storage_receipts, retention_summary, provenance) with restricted
types (str/int/bool/None/list/dict) so CBOR and JCS round-trip losslessly.
- codec.py: encode (Manifest -> canonical CBOR bytes) and decode (CBOR bytes
-> Manifest) via cbor2.
- projection.py: jcs_projection (Manifest -> RFC 8785 canonical JSON) plus
cbor_from_jcs for cross-format round-trip verification.
- digest.py: manifest_digest returns the BLAKE3 content address of the
manifest's canonical CBOR bytes (ADR-0001).
- __init__.py: re-exports the public surface.
tests/unit/test_manifest.py:
- decode(encode(m)) == m round-trip (hypothesis-parameterised).
- JCS↔CBOR round-trip: encode(decode(cbor_from_jcs(jcs(m)))) == encode(m).
- Byte stability of the canonical CBOR encoder across calls.
- manifest_digest matches independent BLAKE3 over encode(m).
- Decode rejects non-map CBOR.
- JCS projection sorts keys lexicographically.
Deps: jcs added to project requirements; mypy override for the jcs package
(no stubs published yet).
Gates: ruff clean, mypy --strict clean on 26 files, 26 tests pass.

WP-0001-T001: service scaffold (Python, FastAPI, uv, ruff, mypy, pytest)
Lands the smallest credible foundation per ADR-0005:
- pyproject.toml: hatchling build, runtime deps (FastAPI, uvicorn, SQLAlchemy 2.0,
asyncpg, aiosqlite, alembic, blake3, cbor2, typer, structlog, pydantic,
pydantic-settings); dev deps (pytest, pytest-asyncio, httpx, hypothesis, ruff,
mypy); ruff + mypy --strict + pytest configured.
- uv.lock committed.
- Makefile thin shims: install / dev / test / lint / format / type / migrate / clean.
- src/artifactstore/ package skeleton with placeholder __init__.py per concern:
identity, manifest, events, retention, audit, storage, dataplane, registry,
api/http (minimal FastAPI app, GET / scaffold banner), cli (typer app with
version subcommand), config (pydantic-settings).
- tests/{unit,integration}/conftest.py present; unit smoke tests assert package
imports, HTTP root route, CLI version round-trip, settings defaults.
- .env.example documents ARTIFACTSTORE_DATABASE_URL,
ARTIFACTSTORE_STORAGE_LOCAL_ROOT, ARTIFACTSTORE_LOG_LEVEL.
- README updated with install / dev / test instructions.
- .gitignore: claude local state, local runtime data (var/, sqlite db).
make lint && make type && make test pass on a clean checkout (4 tests, 20
source files type-clean under mypy --strict).
