WP-0001-T008: operator docs + ADR cross-linking; mark WP-0001 done

docs/OPERATOR.md (new): runbook with prerequisites, quick start,
environment variables, SQLite + PostgreSQL setup, storage layout,
CLI reference, HTTP /health reference, an end-to-end Python smoke
test (create_package -> ingest_file -> finalize -> manifest), the
replay / disaster-recovery procedure, common failure modes, and a
References section that links every ADR (0001..0006), the
blueprint, platform ambition, roadmap, and assembly experiment.

README.md: refreshed to v0.1 baseline status. Quick-start uses the
real flow (uv sync, migrate-fresh, dev, /health, artifactstore health).
Make targets and CLI commands tabulated. Links docs/OPERATOR.md.

AGENTS.md: Current Repo Shape now reflects the landed scaffold +
library + CLI + HTTP app rather than "no runnable scaffold yet";
links OPERATOR.md and lists the canonical local commands.

workplans/ARTIFACT-STORE-WP-0001-service-baseline.md:
- T008 marked done.
- frontmatter status: active -> done; updated: 2026-05-16.

All ten WP-0001 tasks are now done (T001/T002/T003/T008/T009/T010/
T011/T012/T013/T014). Foundation workplan retires.

Gates: ruff clean, mypy --strict clean, 83 tests pass.

+# Operator Guide
+
+Status: v0.1 (WP-0001 baseline)
+Updated: 2026-05-16
+
+This guide is the user manual for running `artifact-store` v0.1 — the
+library + CLI + minimal HTTP app that landed in WP-0001. Ingest, finalize,
+and retrieve workflows go through the Python library today; the HTTP
+upload API arrives in WP-0002.
+
+For architectural background see
+[ARCHITECTURE-BLUEPRINT.md](ARCHITECTURE-BLUEPRINT.md), the ADRs under
+[adr/](adr/), and the [ROADMAP](ROADMAP.md).
+
+## Prerequisites
+
+- Python 3.12 or 3.13
+- [`uv`](https://docs.astral.sh/uv/) on the PATH (one static binary)
+- A POSIX-ish shell (Linux, macOS, WSL2)
+
+The pinned tech stack is documented in
+[ADR-0005](adr/0005-v1-tech-stack.md).
+
+## Quick start
+
+```sh
+uv sync --all-extras       # install deps; produces .venv/ and uv.lock
+cp .env.example .env       # optional — the defaults work out of the box
+
+make migrate-fresh         # creates ./var/artifactstore.db and applies migrations
+make dev                   # uvicorn on 127.0.0.1:8000
+```
+
+In another terminal:
+
+```sh
+curl -s http://127.0.0.1:8000/health | python3 -m json.tool
+artifactstore health
+```
+
+Both should report ``status: ok``.
+
+## Environment variables
+
+All settings are prefixed with ``ARTIFACTSTORE_`` and read by
+`pydantic-settings` from the environment and (optionally) `./.env`.
+
+| Variable                          | Default                                       | Purpose |
+|-----------------------------------|-----------------------------------------------|---------|
+| `ARTIFACTSTORE_DATABASE_URL`      | `sqlite+aiosqlite:///./var/artifactstore.db`  | SQLAlchemy async URL. Alembic translates `+aiosqlite` and `+asyncpg` to their sync drivers at migrate-time. |
+| `ARTIFACTSTORE_STORAGE_LOCAL_ROOT`| `./var/storage`                               | Root directory for the local filesystem storage backend. Created on first use. |
+| `ARTIFACTSTORE_LOG_LEVEL`         | `INFO`                                        | Python logging level (`DEBUG` / `INFO` / `WARNING` / `ERROR`). |
+
+See [`.env.example`](../.env.example) for the canonical template.
+
+## Database backends
+
+### SQLite (development default)
+
+Zero-config. The database file lives at `./var/artifactstore.db` by default
+and is gitignored.
+
+```sh
+make migrate-fresh    # drop and re-create
+make migrate          # idempotent: apply pending migrations
+```
+
+### PostgreSQL 16+ (shared deployments)
+
+Install the optional `postgres` extra (pulls in `psycopg[binary]` for
+Alembic's sync driver):
+
+```sh
+uv sync --all-extras --extra postgres
+```
+
+Set the URL with the async driver; Alembic switches to `+psycopg` for
+migrations automatically:
+
+```sh
+export ARTIFACTSTORE_DATABASE_URL=postgresql+asyncpg://artifactstore:secret@db.internal:5432/artifactstore
+make migrate
+```
+
+The schema is identical to SQLite (per
+[ADR-0002](adr/0002-event-log-source-of-truth.md) the events table drives
+all materialised views).
+
+## Storage backends
+
+The storage adapter SPI is documented in
+[ADR-0001](adr/0001-content-addressed-storage.md) and
+[ADR-0004](adr/0004-control-plane-data-plane-contract.md).
+
+### Local filesystem (default)
+
+Objects are addressed by content (`blake3:<hex>`) and laid out as
+
+```
+<root>/<algorithm>/<hex[0:2]>/<hex[2:4]>/<hex>
+```
+
+with atomic writes (tmpfile + fsync + rename). The S3-compatible backend
+lands in WP-0004.
+
+## CLI reference
+
+`artifactstore --help` lists every subcommand. The v0.1 set:
+
+| Command                  | Purpose |
+|--------------------------|---------|
+| `artifactstore version`  | Print the package version and exit. |
+| `artifactstore migrate`  | Run `alembic upgrade head` against the configured database. |
+| `artifactstore replay`   | Truncate every materialised view and rebuild it from the event log; prints the highest sequence applied. |
+| `artifactstore health`   | JSON liveness summary (db, backend, status). Same payload as the HTTP `/health` endpoint. |
+
+The CLI is a thin client over `artifactstore.registry.Registry`
+(see [ADR-0005](adr/0005-v1-tech-stack.md)).
+
+## HTTP reference (v0.1)
+
+| Route          | Purpose |
+|----------------|---------|
+| `GET /`        | Service banner (scaffold marker). |
+| `GET /health`  | Liveness summary. Returns ``{status, db, backend, version}``. `status` is `ok` only when both the DB probe (`SELECT 1`) and the backend `health()` succeed. |
+| `GET /docs`    | FastAPI's interactive OpenAPI docs (`/openapi.json` underneath). |
+
+Package CRUD, file upload/download, manifest retrieval, retention controls,
+and the event stream all land in WP-0002–WP-0003. Today they are reachable
+via the Python library.
+
+## End-to-end smoke test (Python library)
+
+This exercises every layer (identity, manifest, events, dataplane, storage,
+registry, replay) end-to-end against the default SQLite + local FS configuration.
+
+```python
+import asyncio
+from collections.abc import AsyncIterator
+from artifactstore.app import build_registry
+from artifactstore.manifest import decode as manifest_decode
+
+
+async def chunks(data: bytes) -> AsyncIterator[bytes]:
+    yield data
+
+
+async def main() -> None:
+    registry = build_registry()
+    try:
+        pkg = await registry.create_package(
+            name="smoke-test",
+            producer="ops",
+            subject="example.org",
+            retention_class="raw-evidence",
+            actor="ops",
+            metadata={"smoke": True},
+        )
+        await registry.ingest_file(
+            pkg, relative_path="hello.txt", media_type="text/plain",
+            stream=chunks(b"hello world"), actor="ops",
+        )
+        manifest_addr = await registry.finalize_package(pkg, actor="ops")
+        cbor = await registry.get_manifest_bytes(pkg, format="cbor")
+        manifest = manifest_decode(cbor)
+        print("package:", pkg)
+        print("manifest digest:", manifest_addr)
+        print("files in manifest:", [f.relative_path for f in manifest.files])
+    finally:
+        await registry.dispose()
+
+
+asyncio.run(main())
+```
+
+Prerequisites: `make migrate-fresh` has been run so the schema and the
+retention class seeds exist.
+
+## Replay / disaster recovery
+
+Every state-changing operation writes one row to `events` and updates the
+materialised views in the same transaction
+([ADR-0002](adr/0002-event-log-source-of-truth.md)). If the materialised
+views are lost or corrupted, rebuild them from the event log:
+
+```sh
+artifactstore replay
+```
+
+The command drops every row from `artifact_packages`, `artifact_files`,
+`storage_locations`, and `retention_state`, then replays the events in
+sequence order through the canonical view writer. The result is
+**byte-identical** to the materialised state before the replay
+(verified by the WP-0001-T013 integration test).
+
+## Failure modes operators should expect
+
+| Symptom                                          | Likely cause                                 | Fix |
+|--------------------------------------------------|----------------------------------------------|-----|
+| `/health` returns `status: degraded`, `db.healthy: false` | DB unreachable or migrations not applied | Check `ARTIFACTSTORE_DATABASE_URL`; run `make migrate`. |
+| `/health` returns `status: degraded`, `backend.healthy: false` | Storage root missing or unreadable | Recreate `ARTIFACTSTORE_STORAGE_LOCAL_ROOT` or fix permissions. |
+| `ObjectNotFoundError` from `get_file`            | Underlying bytes deleted but the file row remains | Investigate; v1 does not garbage-collect orphaned rows (WP-0006). |
+| `DuplicateRelativePathError` from `ingest_file`  | Same package + path ingested twice           | Use a distinct `relative_path` per file within one package. |
