🚨 Critical Issues (Fix This Week)

1. AgentDB Integration - NO UNIT TESTS ❌

• File: src/core/memory/AgentDBIntegration.ts (647 LOC)
• Tests: NONE (0 dedicated tests)
• Impact: Data consistency risk in distributed fleet
• Action: Create tests/unit/memory/AgentDBIntegration.test.ts
• Effort: 3-4 days
• Priority: P0 - BLOCKER

2. QUIC Fallback to TCP Incomplete ❌

• File: src/core/transport/QUICTransport.ts (lines 73-93, 135-162)
• Coverage: ~65% of fallback paths
• Impact: Backward compatibility risk
• Action: Add fallback tests to existing test file
• Effort: 2-3 days
• Priority: P0 - BLOCKER

3. Neural Prediction Failure Handling ⚠️

• File: src/learning/NeuralPatternMatcher.ts (lines 650-702)
• Coverage: ~70% of error paths
• Impact: Graceful degradation uncertainty
• Action: Add failure scenario tests
• Effort: 1-2 days
• Priority: P1 - HIGH
