---

## 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:**

```bash
# 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

---

## 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

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.
