## Files Recommended for Archival

### Priority 1: Historical Monthly Summaries
1. **PROJECT_SUMMARY_2025-12.md**
   - Reason: December 2025 summary, now historical
   - Recommendation: Move to `plans/STATUS/archive/2025/`

### Priority 2: Completed Phase Reports
2. **PHASE1_CODE_REVIEW_REPORT_2025-12-25.md**
   - Reason: Historical phase report, superseded by current status
   - Recommendation: Move to `plans/STATUS/archive/2025/`

3. **PHASE1_VALIDATION_REPORT_2025-12-25.md**
   - Reason: Historical validation report, superseded
   - Recommendation: Move to `plans/STATUS/archive/2025/`

4. **MEMORY_SYSTEM_VERIFICATION_REPORT_2025-12-24.md**
   - Reason: Historical verification (postcard migration)
   - Recommendation: Move to `plans/STATUS/archive/2025/`

### Priority 3: Historical Implementation Plans
5. **IMPLEMENTATION_PHASE1.md**
   - Reason: Configuration optimization, now complete
   - Recommendation: Move to `plans/STATUS/archive/2025/`

6. **IMPLEMENTATION_PHASE2.md**
   - Reason: Algorithmic improvements, most complete
   - Recommendation: Move to `plans/STATUS/archive/2025/`

## Next Steps

1. **Archive Historical Files** - Move 6 files to archive folder
2. **Create Archive Structure** - Organize by year/month
3. **Update Navigation** - Update STATUS folder README
4. **Continue File Splitting** - Address remaining 4 large files

---

**Summary**: All current STATUS files updated to reflect v0.1.12 state. 6 historical files recommended for archival to maintain clean, organized documentation structure.
