## False Positives

## Deferred to Tech Debt
| Issue | File:Line | Risk Factor |
|-------|-----------|-------------|
| SRP: Extract MessageDeliveryPipeline + StalenessDetector from TmuxConnector | tmux-connector.ts (full file) | Architectural overhaul — complexity symptoms already fixed via helper extraction (batch-5). Class extraction is speculative: Phase 2/3 will reshape the connector when real consumers emerge. Deferring avoids regressions in tested code for organizational improvement with no correctness impact. |
