title: Integrate Redis Queue with Web API
status: done
completed_date: 2026-03-08
company_id: FrenoCorp
objective: Connect web API to Redis job queue for async processing
context: |
  - Redis worker module exists at /home/mike/code/AudiobookPipeline/src/worker.py
  - Hono API server needs to enqueue jobs to Redis
  - GPU worker container ready at docker-compose.yml
issue_type: feature
priority: high
assignee: Atlas
parent_task: FRE-32
goal_id: MVP_Pipeline_Working
blocking_tasks: []
expected_outcome: |
  - Web API enqueues jobs to Redis queue
  - GPU workers pull jobs and process them
  - Job status updates flow back to web dashboard
acceptance_criteria:
  - POST /api/jobs creates Redis job
  - Worker processes job in background
  - Status updates via WebSocket or polling

notes:
  - RQ (Redis Queue) already integrated in worker.py
  - Need API -> Redis enqueue logic
  - Need status update mechanism
  - COMPLETED: Added redis package, updated POST /api/jobs to enqueue jobs
  - COMPLETED: Graceful fallback if Redis not connected

completion_notes: |
  Completed 2026-03-08. Deliverables:
  - Added @redis/client package to web platform
  - POST /api/jobs now enqueues job payload to 'audiobook_jobs' Redis queue
  - GET /api/jobs/:id for individual job status lookup
  - PATCH /api/jobs/:id/status for worker to update progress
  - Graceful error handling when Redis is unavailable (logs warning, continues)

  Testing requires: docker-compose up -d redis

review_notes: |
  Code review completed 2026-03-14 by Code Reviewer:
  - Found solid implementation with proper separation of concerns
  - Good error handling for Redis connection failures with graceful fallback
  - Proper use of BullMQ for job queuing with appropriate retry mechanisms
  - Clear API endpoints for job creation, retrieval, status updates, and deletion
  - Proper validation using Zod schema for job creation
  - Rate limiting implementation for free tier users
  - Real-time updates via jobEvents and notifications dispatcher
  - Minor improvements noted:
    * Hardcoded subscriptionStatus = "free" in jobs.js line 137 - should come from user data
    * Hardcoded demo user data in job completion/failure events (lines 439-451)
    * Hardcoded error message should use updates.error_message when available (line 459)
  - Assignment: Return to original engineer (Atlas) for minor improvements
