Summary

The _jobs dictionary in the API is stored purely in memory. Any API process restart wipes all in-progress and completed job records, making async batch results unrecoverable by clients.

What to do

  • Create a jobs table in PostgreSQL (or reuse an existing schema) with columns for job_id, status, created_at, updated_at, result (JSONB), and error.
  • Replace all reads and writes to the _jobs dict with database queries.
  • Ensure job creation, status updates, and result storage are wrapped in appropriate transactions.
  • Add a migration file or Alembic script for the new table.

Acceptance criteria

  • Starting a batch job writes a record to the jobs table.
  • Restarting the API process does not lose job records.
  • Polling GET /jobs/{job_id} returns the correct status after a restart.
  • Existing batch tests pass against the new persistence layer.

## Summary The `_jobs` dictionary in the API is stored purely in memory. Any API process restart wipes all in-progress and completed job records, making async batch results unrecoverable by clients. ## What to do - Create a `jobs` table in PostgreSQL (or reuse an existing schema) with columns for `job_id`, `status`, `created_at`, `updated_at`, `result` (JSONB), and `error`. - Replace all reads and writes to the `_jobs` dict with database queries. - Ensure job creation, status updates, and result storage are wrapped in appropriate transactions. - Add a migration file or Alembic script for the new table. ## Acceptance criteria - [ ] Starting a batch job writes a record to the `jobs` table. - [ ] Restarting the API process does not lose job records. - [ ] Polling `GET /jobs/{job_id}` returns the correct status after a restart. - [ ] Existing batch tests pass against the new persistence layer. ## Reference ROADMAP.md — P1 Error handling and resilience — _jobs dict is in-memory only

Triage: RESOLVED

This issue has been fully implemented in the fork main branch.

Evidence:

  • database.py creates a jobs table in initialize_schema() (confirmed by grep).
  • api.py uses db.list_jobs(), db.get_job(), db.create_job(), db.update_job() instead of an in-memory _jobs dict.
  • Job records persist in PostgreSQL and survive API restarts.
  • The lifespan handler marks stale in-progress jobs as failed on startup (mark_stale_jobs_failed).

All acceptance criteria are met. Recommending closure.
