Context

The _jobs dictionary in the API is held in process memory. Every API restart wipes all in-flight and completed job results, making batch analysis unreliable in a containerised environment.

Roadmap reference: ROADMAP.md > P1 > Error handling and resilience > _jobs dict is in-memory only

What to do

  1. Add a jobs table to the PostgreSQL schema (columns: id, status, created_at, updated_at, result JSONB, error TEXT).
  2. Replace all reads/writes to _jobs with database queries.
  3. Update the GET /jobs/{job_id} and GET /jobs endpoints to query the database.
  4. Write a migration script or update the existing schema initialisation.
  5. Add tests that verify job state survives a simulated restart (i.e., a new handler instance can read jobs created by a previous one).

Acceptance criteria

  • Submitting a batch job, restarting the API, and then polling GET /jobs/{job_id} still returns the correct status and result.
  • The _jobs in-memory dict is fully removed.
  • No existing batch-processing tests are broken.
