KEY FEATURES
================================================================================

✅ Metadata Inheritance (5-layer cascading)
   - Global defaults → Scope → Type → File → References
   - Reduces metadata per-file by 50-80%

✅ Data File References (Single Source of Truth)
   - authors.yml, licenses.yml, tags.yml
   - Edit once, updates everywhere

✅ Programmatic Rendering (4 output formats)
   - Markdown (navigation breadcrumbs)
   - HTML (with meta tags)
   - JSON (API access)
   - GitHub Issues (automated)

✅ Publishing Safety (Automatic Sanitization)
   - internal_only: true files excluded from dist/
   - Sensitive metadata stripped
   - No manual review needed

✅ Version-Controlled (No Database)
   - Git as source of truth
   - Full audit trail
   - Change history preserved

================================================================================
IMPLEMENTATION TIMELINE
================================================================================

Phase 1: Foundation (2-3 hours)
- Metadata resolver with cascading
- Reference resolution (author, license, tags)
- Validation framework
- 90%+ test coverage

Phase 2: Rendering (3-4 hours)
- Markdown, HTML, JSON renderers
- Metadata footer injection
- Navigation generation
- 85%+ test coverage

Phase 3: Integration (2-3 hours)
- Integrate into command pipeline
- Template generation with metadata
- Publishing respects metadata flags

Phase 4: Commands (2-3 hours)
- /validate-metadata
- /render-content (formats: markdown, html, json)
- /audit-metadata
- /update-defaults

Total: 10-15 hours spread over 2-3 weeks

================================================================================
SUCCESS METRICS
================================================================================

Metadata Duplication:      50-80% → <5%
Author Name Consistency:   Varies → 100%
Copyright Updates:         Manual 640 files → 1 file
Publishing Safety:         Manual review → Automatic
Content Reusability:       1 format → 4+ formats
Build Time (metadata):     N/A → <2s
Test Coverage:             N/A → 90%+

================================================================================
NOTES FOR TEAM
================================================================================

This specification is:
✓ Engineering-ready (can implement immediately)
✓ Self-contained (all details in one folder)
✓ Backward-compatible (existing files still work)
✓ Non-breaking (additive implementation)
✓ Production-safe (validation prevents leaks)

This specification is NOT:
✗ Implementation code (just design + requirements)
✗ Database schema (Git-backed, no DB needed)
✗ Customer-facing (internal architecture doc)
✗ Real-time system (build-time processing only)

================================================================================
