## Notes

1. **Buffer Size Conflict (GAP-L4)**: Now **RESOLVED**
   - Correct value: **300 messages** (per Req-FR-26)
   - Configuration file showing 300000 was an error

2. **Critical File**: architecture-diagrams.md contains the most requirement annotations
   - 50+ instances across multiple Mermaid diagrams
   - Requires careful attention to detail
   - Visual verification needed after updates

3. **Testing Requirements**: Complete category shift
   - Old: Req-NFR-7, 8, 9, 10
   - New: Req-Test-1, 2, 3, 4
   - More semantically correct categorization

4. **Document Versioning**: All files should be updated to version 1.1
   - Reflects Phase 2 requirement ID corrections
   - Maintains traceability to Phase 1 updates
