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. |
