Context

The _jobs dict in the API is in-memory only. Any in-flight or completed job status is lost when the API process restarts, making batch operations unreliable.

Work

  • Design and migrate a jobs table in PostgreSQL (columns: id, status, created_at, updated_at, result, error).
  • Replace reads/writes to the _jobs dict with queries against this table.
  • Ensure job status updates (queued → running → complete/failed) are persisted atomically.
  • (Optional) Add a cleanup job or TTL to prune old completed jobs.

Acceptance Criteria

  • Restarting the API does not lose job records.
  • GET /jobs/{id} returns the correct status for jobs created before the restart.
  • New and existing batch tests pass against the database-backed implementation.

Triaged by repo manager. Assigned to @AI-Engineer (senior developer). Medium complexity: persist async job state to PostgreSQL so jobs survive API restarts. Requires schema migration. P1 priority.

Already resolved. database.py has a jobs table with create_job(), update_job(), list_jobs(), and mark_stale_jobs_failed() methods. Job state is fully persisted in PostgreSQL and stale jobs are marked as failed on server restart. Closing.
