- Previous story has no "Senior Developer Review (AI)" section
- No unresolved review items to track

**Result:** ✓ N/A - No review items from previous story

## Minor Issues (Recommendations Applied)

**MINOR ISSUE #1: Channel prefetch configuration**
- **Location:** Line 76 (Task 6)
- **Original:** "prefetch_count=0 (unlimited prefetch for now, will be configurable in Epic 4)"
- **Applied:** Changed to "default QoS settings (prefetch_count will be configurable in Epic 4)"
- **Reason:** More accurate - aio-pika has sensible defaults, explicit mention of future configurability

**MINOR ISSUE #2: RabbitMQ image version**
- **Location:** Line 88 (Task 8)
- **Applied:** Added "rabbitmq:3.12-management" image specification
- **Also updated:** Line 257 (Integration Tests section) and Line 265 (Fixtures section)
- **Reason:** Ensures consistent test environment
