---

Known Issues / Blockers

None - All systems operational

Warnings (Non-blocking):

• npm deprecation warnings (expected, not critical)
• GitHub account not yet set up (deferred)
• ProtonBridge not configured (deferred to production)

---

Technical Decisions Made

MongoDB Port: 27017

• Reason: Standard default, no conflicts detected
• Alternative considered: 27029 (not needed)

Application Port: 9000

• Reason: Per specification, 9000 range for application
• Verified available

Git Strategy

• Branch: main (renamed from master)
• Workflow: Feature branches (not yet created)
• Remote: GitHub primary + Codeberg/Gitea mirrors (pending)

Te Tiriti Approach

• Decision: Respect as strategic baseline, defer direct engagement
• Rationale: Build value first before approaching Māori organizations
• Implementation: Document principles, use published standards (CARE Principles)

Phase 2 AI Features

• Decision: Feature flags set to false in Phase 1
• Rationale: Build infrastructure first, enable AI when Claude API integrated

---

Verification Checklist for Next Session

Run these commands to verify system state:

# 1. Verify MongoDB running
sudo systemctl status mongodb-tractatus
lsof -i :27017

# 2. Verify database
mongosh mongodb://localhost:27017/tractatus_dev --eval "db.getCollectionNames()"

# 3. Verify Git status
git status
git log --oneline -5

# 4. Verify dependencies
npm list --depth=0

# 5. Test server startup
npm run dev
# Should see: ✅ Connected to MongoDB, Server listening on port 9000
# Ctrl+C to stop

# 6. Check environment
cat .env | grep -v "SECRET"

Expected Results:

• MongoDB: active (running)
• Collections: 10 listed
• Git: On branch main, nothing to commit, working tree clean
• Server: Starts successfully, connects to DB

Recommendations for Next Session

Immediate Priorities

1. Build core API routes - Complete the backend foundation
2. Create document migration script - Import framework documentation
3. Test API with real data - Verify models work end-to-end

Strategic Considerations

• No shortcuts: Continue world-class quality approach
• Governance first: All features must align with TRA-VAL-0001
• Test incrementally: Each route should be tested before moving on
• Git commits: Continue detailed commit messages for each feature

Session Time Management

• API routes: ~40% of next session
• Migration pipeline: ~20%
• Testing/refinement: ~20%
• Governance services (start): ~20%

---

Success Metrics

Foundation Phase (This Session):

• ✅ 10/21 tasks complete (47.6%)
• ✅ Infrastructure 100% operational
• ✅ Database layer 100% complete
• ✅ Server foundation 100% complete
• ✅ Zero technical debt
• ✅ All systems tested and working

Quality Indicators:

• ✅ No placeholder code
• ✅ No fake data
• ✅ Complete error handling
• ✅ Security best practices applied
• ✅ Proper separation of concerns
• ✅ Comprehensive documentation

---

Session Notes

What Went Well

• Clear communication on requirements
• Systematic approach (infrastructure → utilities → models → server)
• Proper testing at each stage
• User running setup commands in parallel
• Clean Git workflow with meaningful commits

Challenges Overcome

• Initial confusion about scope (resolved via detailed spec reading)
• MongoDB systemd status check (resolved - service was actually running)
• npm deprecation warnings (clarified as non-blocking)

Technical Highlights

• Complete separation from family-history project
• Production-ready error handling from start
• Tractatus framework integrated into core architecture
• Governance document adaptation (SyDigital → Tractatus)

---

Handoff to Next Session

Status: Ready for feature development

Next Claude Code Instance Should:

1. Read NEXT_SESSION.md first
2. Verify all systems operational (run verification checklist)
3. Review CLAUDE.md for project context
4. Check Git log to understand recent changes
5. Begin with API routes implementation

Context Preserved In:

• Git commit history (detailed messages)
• CLAUDE.md (project conventions)
• TRA-VAL-0001 (values framework)
• This closedown document

No Lossy Handoff: All decisions, rationale, and context documented.
