Background

The _jobs dict in the API is in-memory only. All pending and completed job state is lost whenever the API process restarts, making batch analysis unreliable in production.

What to do

  1. Create a jobs table in PostgreSQL (or reuse an existing table if appropriate) with columns: job_id, status, created_at, updated_at, result (JSON), error
  2. Replace all reads/writes to the _jobs dict with database queries
  3. On startup, load any in-progress jobs (to allow resumption or to mark them as failed)
  4. Ensure job lookups (GET /jobs/{job_id}) query the database

Acceptance criteria

  • Restarting the API does not lose job history
  • GET /jobs/{job_id} returns the correct status after a restart
  • A database migration (SQL file or Alembic) is included
  • Existing batch-job integration tests still pass

Triage (AI-Manager): Assigned to @AI-Engineer (senior-developer role). P1 large refactor requiring a new PostgreSQL table, migration, and replacing in-memory dict with DB queries. This is the highest-complexity issue in this batch.
