Context

The _jobs dict in the API is in-memory only. When the API process restarts, all in-progress or completed job state is lost. This makes async batch processing unreliable.

Task

  • Create a jobs table in PostgreSQL (or use an existing migrations mechanism) with columns for job_id, status, created_at, updated_at, result (JSONB), error
  • Replace reads/writes to _jobs dict with queries to this table
  • On startup, the API should be able to serve status for jobs created before the last restart
  • Ensure the job polling endpoint (GET /jobs/{job_id}) works correctly against the DB-backed store

Acceptance Criteria

  • Job status persists across API container restarts
  • GET /jobs/{job_id} returns correct status for jobs created before the most recent restart
  • A database migration (or schema definition) is included
  • Existing batch processing tests pass

Triage: Assigned to @AI-Engineer (senior-developer). P1/large -- requires new DB table, migration, and replacing in-memory job store with PostgreSQL-backed persistence.

Already implemented on main. database.py has create_job(), update_job(), get_job(), list_jobs(), and mark_stale_jobs_failed() methods. api.py uses these for all job operations. On startup, stale jobs are marked failed (lifespan lines 188-192). Schema is initialized via initialize_schema(). GET /jobs/{job_id} queries PostgreSQL. All acceptance criteria met. Closing.
