Ruff autofix removed pre-existing F401 unused imports across adapters,
context, compiler, extractor, scheduler, web, and main. Also reordered
models.py so its SQLAlchemy imports sit at the top of the file
(E402 was triggered by the inline `utcnow` helper definition).
Added a [dependency-groups] dev block (pytest, pytest-cov, ruff) so the
zero-check test gauntlet — which runs `pytest --cov --cov-report=term-missing`
— can resolve its plugins without a manual `uv pip install pytest-cov`.
Swap the SQLite backing store for petalbrain Postgres + pgvector, modeled
on vault-mcp. All second-brain relational tables now live in the
`second_brain` schema (owned by the lovebug role); embeddings are written
to the shared public.embeddings table.
Locked design decisions (per Travis):
- DB: existing petalbrain Postgres, second_brain schema, lovebug role.
- Connection: containerized homelab-postgres:5432, plain psycopg_pool
(min=1/max=10), no PgBouncer.
- ORM stays SQLAlchemy; int autoincrement PKs + naive UTC DateTime.
- Embeddings: reuse shared public.embeddings keyed by
(source_schema='second_brain', source_table='extractions', source_id,
model='nomic-embed-text'). Summaries only for this round.
- Pipeline: chunk_text → Ollama nomic-embed-text → delete-before-insert
upsert, with graceful degradation (no DB / no Ollama → log + skip).
- Alembic stands up second-brain's own schema; public.embeddings stays
out-of-band.
- File-based wiki compiler is unchanged.
No SQLite data import — starting clean.
This commit is the scaffolding only; `alembic upgrade head` and a smoke
test of the embedding path are the next checkpoint.
Run extraction under the Max OAuth subscription via `claude -p` instead
of the per-token Anthropic API. The new src/second_brain/llm/claude_cli.py
spawns the CLI in a hermetic tempdir so the host project's CLAUDE.md,
hooks, MCP config, and settings don't leak into the prompt. Uses
--json-schema with LLMExtraction.model_json_schema() so the CLI guarantees
valid structured output — replaces the brittle markdown-fence stripping
in the old engine. The Anthropic SDK is preserved as an optional "api"
backend selectable via config.
While in here, fix a handful of blockers that the smoke test surfaced:
- scheduler filtered ANALYZED instead of TRANSCRIBED, so it never
actually advanced any sources
- process command read sources in a closed session, raising
DetachedInstanceError before any work happened
- config.prompts_dir walked one parent too many, resolving outside
the project and forcing the fallback prompt for every domain
- compiler called git rev-parse against a vault that was never
git-init'd; now auto-inits with an empty seed commit and skips empty
commits cleanly
- datetime.utcnow() deprecated in 3.12+ — single utcnow() helper in
models.py keeps naive UTC semantics so no DB migration is needed
- sess.query(...).get() deprecated in SA 2.x → sess.get(...)
- dead `import anthropic` removed from compiler
Smoke test (article → process → accept → compile) succeeds end-to-end
with ANTHROPIC_API_KEY unset. a-review run saved under reviews/.
