Summary

Consolidate duplicate documentation files (especially CHANGELOG.md) and relocate multiple root-level documentation files to appropriate docs/ subdirectories to improve repository organization and eliminate maintenance duplication.

Background (Why)

• CHANGELOG.md exists at both root (1044 lines) and docs/ (595 lines) - content divergence risk
• Multiple documentation files at root level break standard repository structure
• BASELINE.md, STRUCTURE.md, MIGRATION.md, UDP_SUPPORT.md all at root level
• Maintaining duplicate files increases risk of inconsistent information
• Current structure doesn't follow ecosystem documentation standards

Current root-level documentation clutter:

network_system/
├── README.md                 # OK - stays at root
├── README.kr.md              # OK - stays at root
├── CHANGELOG.md              # DUPLICATE - also in docs/
├── BASELINE.md               # Should be in docs/performance/
├── STRUCTURE.md              # Should be merged with docs/PROJECT_STRUCTURE.md
├── MIGRATION.md              # Should be in docs/advanced/
└── UDP_SUPPORT.md            # Should be in docs/guides/

Files to Modify

CHANGELOG Comparison

Implementation Plan (How)

Phase 1: CHANGELOG Consolidation

1. Compare root CHANGELOG.md with docs/CHANGELOG.md
2. Identify entries in root that are missing from docs/
3. Merge unique entries into docs/CHANGELOG.md
4. Delete root CHANGELOG.md

Phase 2: STRUCTURE.md Consolidation

5. Compare root STRUCTURE.md with docs/PROJECT_STRUCTURE.md
6. Merge unique content into docs/PROJECT_STRUCTURE.md
7. Delete root STRUCTURE.md

Phase 3: File Relocations

8. Move BASELINE.md to docs/performance/BASELINE.md
9. Move MIGRATION.md to docs/advanced/MIGRATION.md
10. Move UDP_SUPPORT.md to docs/guides/UDP_SUPPORT.md

Phase 4: Link Updates

11. Update README.md to reflect new file locations
12. Update docs/README.md navigation
13. Search and update any internal cross-references
14. Update any external documentation links

Phase 5: Verification

15. Verify all documentation links work
16. Verify no duplicate files remain
17. Verify CHANGELOG is complete after merge

Acceptance Criteria

• Only README.md and README.kr.md at root level
• Single CHANGELOG.md in docs/ with all history
• BASELINE.md in docs/performance/
• MIGRATION.md in docs/advanced/
• UDP_SUPPORT.md in docs/guides/
• All internal documentation links are valid
• No content loss from consolidation
• Documentation structure matches ecosystem standard
