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Outdated Information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 ❓ Scan for outdated code examples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• ⚠️ Needs Update: Missing diagrams or outdated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• ❌ Major Issues: Significantly outdated or missing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
