Schema (src/artifactstore/db/schema.py):
- events table (ADR-0002 source of truth): sequence BIGSERIAL PK, created_at,
event_type, subject_kind, subject_id, actor, payload (CBOR bytes),
payload_digest. Indexes on (subject_kind, subject_id) and
(event_type, sequence).
- artifact_packages, artifact_files, storage_locations, retention_state
(materialised views over events).
- retention_classes (seed table) and metadata_schemas (config table).
- ADR-0001 columns present: digest_algorithm, digest_primary, digest_sha256,
content_address. Blueprint tiering columns present: retrieval_tier
(default 'hot'), restore_status.
- Types portable: SQLAlchemy 2.0 Core with JSON().with_variant(JSONB, 'postgresql'),
Uuid, LargeBinary, DateTime(timezone=True), Boolean false() default.
Seed (src/artifactstore/db/seed.py): five v1 retention classes (transient,
raw-evidence, summary-evidence, release-evidence, permanent-record) with
default durations in seconds; permanent-record has no expiry.
Alembic:
- alembic.ini with sync sqlite URL default; path_separator=os to silence the
1.13 deprecation warning.
- migrations/env.py: translates async URLs (+aiosqlite, +asyncpg) to sync
counterparts at migrate-time so a single ARTIFACTSTORE_DATABASE_URL works
for both runtime (async) and Alembic (sync).
- migrations/script.py.mako template.
- migrations/versions/20260516_0001_initial.py: metadata.create_all + bulk
insert of retention class seeds.
Make:
- make migrate: alembic upgrade head (ensures var/ exists).
- make migrate-fresh: drop local SQLite + re-run.
Deps: psycopg[binary] added as optional `postgres` extra (PostgreSQL prod
path; SQLite default for dev needs no extra).
Tests:
- tests/unit/test_db_schema.py: every expected table present; ADR-0001 and
tiering columns present; seed has the five v1 classes; permanent-record
has no default_duration; create_all + FK insert + Boolean default
round-trip on in-memory SQLite.
- tests/integration/test_migrations.py: alembic upgrade head against a
tempfile SQLite produces all tables (+ alembic_version) and the seed rows.
Gates: ruff clean, mypy --strict clean on 32 files, 38 tests pass.

Aligns the v1 architecture with the longer-horizon platform thesis so we can
start implementation without the schema-level inconsistencies the prior
review surfaced.
ADRs (docs/adr/0001..0006): content-addressed dual-digest storage, append-only
event log as source of truth, canonical CBOR manifests, control/data-plane
contract, v1 tech stack (Python 3.12 / uv / FastAPI / SQLAlchemy Core +
asyncpg / Alembic / cbor2 / blake3 / ruff / mypy / pytest / typer), OCI
compatibility kept reachable.
Architecture blueprint rewritten to v2: library-first (ffmpeg-shaped) module
layout, materialised-view data model over the event log, upload-session and
event-stream endpoints pinned, retrieval tiering promoted into the schema.
Roadmap added (docs/ROADMAP.md) with three phases. WP-0001 rewritten as the
Foundation plan (scaffold + kernels + local FS + minimal app). WP-0002..0005
created carrying the existing state_hub_task_ids forward semantically:
ingestion API (T004), retention lifecycle (T005), S3-compatible backend
(T006), guide-board pilot (T007). T001/T002/T003/T008 remain in WP-0001
with refined acceptance.
README and AGENTS.md refreshed to reflect the new repo shape.

Captures the longer-horizon thesis (sovereign-cloud artifact substrate)
alongside the carefully-scoped v1 INTENT. PLATFORM-AMBITION records nine
schema/contract commitments the v1 must preserve to keep that horizon
reachable. ASSEMBLY-EXPERIMENT frames an opt-in research line on
ffmpeg-grade hand-tuned asm with an MIT-0 vs LGPL-aware reuse map.
