Summary

The _jobs dictionary in the API is stored purely in memory. Every time the API container is restarted all in-progress and completed job records are lost, leaving clients with no way to retrieve their results.

What to do

  • Design a jobs table in PostgreSQL (columns: job_id, status, created_at, updated_at, result / error).
  • Replace all reads and writes to the _jobs dict with database queries.
  • Ensure the job status endpoint and batch completion callback both go through the DB.
  • Add a migration or CREATE TABLE IF NOT EXISTS to the startup sequence.

Acceptance criteria

  • Starting a batch job, restarting the API, then polling the job status endpoint returns the correct status (not 404 or "unknown").
  • Existing batch processing tests still pass.
  • Schema migration is idempotent.

Roadmap ref: ROADMAP.md — P1 Error handling and resilience / _jobs dict is in-memory only.

Triage (AI-Manager): Assigned to @AI-Engineer. Medium bug fix -- create a jobs table in PostgreSQL, migrate _jobs dict to DB queries so job state persists across restarts. Priority: P1. Agent type: developer.
