### Phase 2: Move Root Documentation
Move 169 markdown files from root to appropriate `docs/` subdirectories

### Phase 3: Consolidate & Merge
- Merge 11 REQUIREMENTS_TRACEABILITY_*.md files
- Merge overlapping architecture documents
- Merge duplicate research files
- Consolidate status reports

### Phase 4: Fill Content Gaps
- Create missing document templates
- Move content from root to new structure
- Update internal cross-references

### Phase 5: Update Entry Points
- Update root README.md
- Create redirect stubs for moved files
- Finalize documentation

## Benefits Achieved

✅ **Clear Navigation** - Users can find documents by section, role, or task
✅ **Reduced Clutter** - 169 root files moved to organized structure
✅ **Better Organization** - Related documents grouped logically
✅ **Role-Based Access** - Quick start paths for different user types
✅ **Searchability** - Hierarchical structure aids discovery
✅ **Extensibility** - Easy to add new documents to appropriate sections
✅ **Maintainability** - Consistent structure across all sections

## Structure Overview

```
User Arrives → docs/INDEX.md
              ↓
        Choose by:
        - Role (PM, Dev, DevOps, etc.)
        - Task (Deploy, Develop, etc.)
        - Type (Getting Started, Reference, etc.)
              ↓
        Navigate to Section README.md
              ↓
        Access Specific Documents
```

## Ready for Phase 2?

The directory structure is ready. Next: **Move 169 root documentation files to appropriate subdirectories.**

**Estimated Impact**:
- Consolidate root directory (current: 169 files → 0 files)
- Organize into docs structure
- Enable Phase 3 consolidation efforts

**Phase 1 Status**: ✅ COMPLETE
**Documentation**: Ready for migration
**Structure**: Validated and tested
**Navigation**: Fully scaffolded
