## Gaps Analysis
### Missing Diagrams (Estimated)
Based on initial scan:
- **Architecture docs**: 6 files, need 15+ diagrams total
- **Guides**: 20 files, need 20-30 diagrams total
- **Skills**: 54 files, need 50-80 diagrams total
- **Runbooks**: 4 files, need 8-12 diagrams total
- **Onboarding**: 2 files, need 4-6 diagrams total
**Total diagrams to create**: **~100-150 Mermaid diagrams**
### Outdated Information
**Sources of Truth** for updates:
1. **`_template/`**: 38 TypeScript files
- Module structure (4 modules)
- Basic patterns
- Configuration examples
2. **`iam-service/`**: 176 TypeScript files
- Production patterns (14 modules)
- Advanced features
- Real-world implementations
3. **Recent Git Commits**: 32 feature commits to review
- UI/UX updates (Mood Board, Auth pages)
- IAM enhancements (RBAC, Kubernetes configs)
- Infrastructure updates (Redis, Traefik)
### Coverage Gaps
Missing documentation for:
1. **Event sourcing pattern** (used in `iam-service/src/core/events/`)
2. **Zero-trust architecture** (implemented in `iam-service/src/core/security/`)
3. **Multi-layer caching** (needs detailed doc with flow diagrams)
4. **RBAC advanced patterns** (permission wildcards, temporary assignments)
5. **Compliance framework integration** (GDPR, SOC2 reporting)

## Next Steps
### Immediate Actions (Phase 1.3 completion)
1.**Wait for Mermaid diagram count** (command in progress)
2.**Scan for outdated code examples**
- Compare code in docs vs actual source
- Identify deprecated patterns
3.**Create priority matrix**
- High priority: Architecture + Core Skills + Critical Guides
- Medium priority: Remaining Guides + Skills
- Low priority: Nice-to-have enhancements
### Phase 2 Preparation
Create templates for:
- Architecture documentation
- Guide documentation
- Skill/pattern documentation
- Runbook documentation
Create Mermaid diagram library for common patterns:
- System architecture (C4 model)
- Sequence diagrams (authentication flows)
- Flowcharts (decision trees, workflows)
- Data flow diagrams
- Class diagrams (patterns)

## Status Codes Legend
-**Complete**: Has diagrams, up-to-date, EN/VI parity
- ⚠️ **Needs Update**: Missing diagrams or outdated
-**Unknown**: Needs verification
-**Major Issues**: Significantly outdated or missing
- N/A: Not applicable
---
## Update Strategy
### High Priority (Phase 3)
1. Architecture docs (6 files) - Foundation for everything
2. Core guides (getting-started, local-development, deployment) - Daily use
3. Core skills (project-rules, api-design, database-prisma, security) - Most referenced
### Medium Priority (Phase 4)
4. Remaining guides (8 files) - Important but less frequently used
5. Remaining skills (20+ files) - Complete coverage
6. Runbooks (4 files) - Operational readiness
### Low Priority (Continuous)
7. Onboarding (2 files) - Nice to have polish
8. Additional enhancements - Based on feedback
