Context

Roadmap reference: P1 Error handling and resilience

The _jobs dictionary in the API is held purely in memory. Any API restart (deployment, crash, OOM kill) silently discards all in-progress and completed job records, leaving callers with no way to retrieve their results.

What to do

  1. Create a jobs table in PostgreSQL (or reuse an existing migrations pattern) with columns: id, status, created_at, updated_at, result (JSONB), error.
  2. Replace all reads and writes to _jobs with database queries.
  3. Expose a simple repository/service layer so the route handlers stay thin.
  4. Add a migration (Alembic or raw SQL) so the table is created on deploy.
  5. Update the /jobs/{job_id} and /jobs list endpoints to query the database.

Acceptance criteria

  • Starting a batch job, restarting the API, then polling /jobs/{job_id} returns the correct status and result.
  • The _jobs in-memory dict is removed.
  • A migration script exists that creates the jobs table idempotently.
## Context Roadmap reference: P1 Error handling and resilience The `_jobs` dictionary in the API is held purely in memory. Any API restart (deployment, crash, OOM kill) silently discards all in-progress and completed job records, leaving callers with no way to retrieve their results. ## What to do 1. Create a `jobs` table in PostgreSQL (or reuse an existing migrations pattern) with columns: `id`, `status`, `created_at`, `updated_at`, `result` (JSONB), `error`. 2. Replace all reads and writes to `_jobs` with database queries. 3. Expose a simple repository/service layer so the route handlers stay thin. 4. Add a migration (Alembic or raw SQL) so the table is created on deploy. 5. Update the `/jobs/{job_id}` and `/jobs` list endpoints to query the database. ## Acceptance criteria - Starting a batch job, restarting the API, then polling `/jobs/{job_id}` returns the correct status and result. - The `_jobs` in-memory dict is removed. - A migration script exists that creates the `jobs` table idempotently.

Triage (AI-Manager): Assigned to @AI-Engineer as @senior-developer.

P1 bug-fix, large complexity. This is the most complex issue in the batch. Requires:

  1. Creating a jobs table in PostgreSQL (migration)
  2. Replacing in-memory _jobs dict with DB queries
  3. Adding a repository/service layer
  4. Updating /jobs/{job_id} and /jobs endpoints

This is a multi-file, architecture-level change. Should be done after #1145 (DB pooling refactor) is complete since it depends on proper DB connection management.

Triage (AI-Manager): P1 Stability -- Sprint 1, Batch 2 (Backend Stability)

Priority: HIGH -- In-memory job state is lost on restart. This is a data loss bug.
Assigned to: @AI-Engineer (senior-developer)
Agent type: @senior-developer -- large change, requires new DB schema for job state
Dependencies: #1145 (shared DB connection pool should be in place first)
Execution order: 6 of 25 -- start after #1145 merges

Triage: P1 Resilience -- Assigned to @senior-developer

Priority: P1 (Critical -- Error handling and resilience)
Complexity: Large
Agent: @senior-developer

This is the largest P1 item. Requires creating a jobs table, migration, repository layer, and updating all route handlers that touch the in-memory _jobs dict.

Delegation plan:

  1. Design jobs table schema (id, status, created_at, updated_at, result JSONB, error)
  2. Create migration script
  3. Implement repository/service layer
  4. Replace all _jobs dict usage with DB queries
  5. Update /jobs endpoints
  6. Test restart resilience
