## Issue Summary

### ⚠ Minor Issues (3 issues - Already Fixed)

#### Minor Issue #1: Race Condition Documentation Could Be Enhanced
**Location:** Task 4 (lines 50-54)  
**Description:** Task mentions handling 404 on DELETE, but doesn't explicitly call out this as a race condition scenario (queue deleted between GET and DELETE).  
**Impact:** Minor - implementation guidance is clear, but explicit race condition callout improves understanding.  
**Fix Applied:** Added explicit note in Task 4 about race condition handling.

#### Minor Issue #2: Concurrent Deletion Edge Case Test Guidance
**Location:** Edge Case Tests (lines 284-291)  
**Description:** "Concurrent queue deletion" mentioned without specific test approach guidance.  
**Impact:** Minor - developer may need to determine testing approach (testcontainers vs mocking).  
**Fix Applied:** Added clarification that concurrent deletion tests should use mocking in unit tests (simulate HTTP responses) and testcontainers for integration tests.

#### Minor Issue #3: Safety Check Workflow Could Be More Explicit
**Location:** Architecture Patterns > Safety Validations (lines 158-167)  
**Description:** Safety validation logic is described, but the sequential workflow (GET stats → evaluate → DELETE or block) could be more explicit.  
**Impact:** Minor - information is present but could be clearer for developer.  
**Fix Applied:** Enhanced workflow description with numbered steps and timing information.

## Recommendations

### Priority: LOW (Story is Development-Ready)

All recommendations below are **optional enhancements** that can be considered during implementation:

1. **Consider Adding Safety Check Performance Metric**
   - Current: Performance monitoring tracks total operation time
   - Enhancement: Separately track safety check overhead (<50ms target from tech spec)
   - Benefit: Better visibility into safety check impact on performance

2. **Consider Expanding Force Flag Documentation**
   - Current: Force flag behavior documented in Task 8
   - Enhancement: Add warning about force flag risks (bypasses ALL safety checks)
   - Benefit: Reinforces safety-first mindset in documentation

3. **Consider Adding Safety Check Cache**
   - Current: Safety check makes GET request on every delete
   - Enhancement: Consider caching queue stats with 5s TTL (as mentioned for list operations)
   - Benefit: Reduce overhead for batch deletions (out of scope for this story)

**Note:** These are future enhancements, not blockers. The current story is comprehensive and ready.
