# Next Session Startup - Tractatus Project
**Last Session:** 2025-10-06
**Project:** Tractatus AI Safety Framework Website
**Status:** Foundation Complete, Ready for Feature Development
---
## Quick Context
You are continuing development of the **Tractatus AI Safety Framework** website platform. This is a **separate project** from family-history and sydigital.
**Key Facts:**
- MongoDB: Port 27017, database `tractatus_dev`
- Application: Port 9000
- Phase: 1 (Local Development)
- Progress: 10/21 tasks complete (47.6%)
- Foundation: ✅ COMPLETE
---
## Immediate Verification Steps
**Run these commands first to verify environment:**
```bash
# 1. Navigate to project
cd /home/theflow/projects/tractatus
# 2. Check MongoDB service
sudo systemctl status mongodb-tractatus
# Expected: active (running)
# 3. Check database
mongosh mongodb://localhost:27017/tractatus_dev --quiet --eval "db.getCollectionNames()"
# Expected: Array of 10 collections
# 4. Check Git status
git status
# Expected: On branch main, working tree clean
# 5. Test server
npm run dev
# Expected: Server starts on port 9000, connects to MongoDB
# Ctrl+C to stop
```
**If any checks fail, see troubleshooting in `SESSION_CLOSEDOWN_20251006.md`**
---
## Project Context Files (READ THESE)
**Essential Reading:**
1. `CLAUDE.md` - Complete project context and conventions
2. `SESSION_CLOSEDOWN_20251006.md` - What was accomplished last session
3. `docs/governance/TRA-VAL-0001-core-values-principles-v1-0.md` - Core values (all decisions align here)
**Reference Documentation:**
- `Tractatus-Website-Complete-Specification-v2.0.md` - Full specification
- `ClaudeWeb conversation transcription.md` - Design discussions
- `README.md` - Project overview
---
## Current State Summary
### ✅ What's Complete (10/21 tasks)
**Infrastructure:**
- MongoDB running (port 27017, 10 collections, 51 indexes)
- Express server foundation (port 9000)
- Systemd service configured
- Git repository (main branch, 5 commits)
**Code:**
- Database utilities (4 files: db, logger, jwt, markdown)
- MongoDB models (7 models with full CRUD)
- Middleware (3 files: auth, validation, error)
- Express server with security (Helmet, CORS, rate limiting)
- Configuration management
**Documentation:**
- CLAUDE.md (project conventions)
- README.md (overview)
- TRA-VAL-0001 (governance)
- SETUP_INSTRUCTIONS.md (terminal commands)
### ⏳ What's Pending (11/21 tasks)
**Immediate Priority:**
1. Core API routes (documents, blog, admin, auth)
2. Document migration pipeline
3. Tractatus governance services (InstructionClassifier, etc.)
**Later:**
4-11. Frontend features (audience paths, demos, AI curation, etc.)
---
## Recommended Next Steps
### Option A: Build Core API Routes (Recommended)
**Start here:**
```bash
# Create route files
touch src/routes/documents.routes.js
touch src/routes/blog.routes.js
touch src/routes/auth.routes.js
touch src/routes/admin.routes.js
touch src/routes/index.js
# Create controllers
touch src/controllers/documents.controller.js
touch src/controllers/blog.controller.js
touch src/controllers/auth.controller.js
touch src/controllers/admin.controller.js
```
**Then implement:**
1. **Auth routes** first (login, verify token)
2. **Documents routes** (CRUD for framework docs)
3. **Blog routes** (public read, admin create)
4. **Admin routes** (moderation queue, stats)
**Update `src/server.js`:**
- Import routes from `src/routes/index.js`
- Mount under `/api`
### Option B: Document Migration Pipeline
**Start here:**
```bash
# Create migration script
touch scripts/migrate-documents.js
touch scripts/seed-admin.js
```
**Implement:**
1. Script to read markdown files from `docs/markdown/`
2. Parse with front matter extraction
3. Convert to HTML
4. Store in MongoDB via Document model
5. Verify migration worked
### Option C: Governance Services
**Note:** More complex, may want API routes first for testing
---
## Important Reminders
### Project Conventions (from CLAUDE.md)
**Ports:**
- MongoDB: 27017 (NOT 27027 like family-history)
- Application: 9000
**Separation:**
- This is SEPARATE from family-history and sydigital
- No shared code/dependencies
- Verify context before running any commands
**Quality Standards:**
- No shortcuts
- No fake data
- World-class quality
- All decisions align with TRA-VAL-0001
**Git Workflow:**
- Commit after each major feature
- Detailed commit messages
- Branch: main
### Values Framework
**All features must align with TRA-VAL-0001:**
- Sovereignty & Self-determination
- Transparency & Honesty
- Harmlessness & Protection
- Human Judgment Primacy
- Community & Accessibility
**Decision Framework:**
1. Does this require human approval? (If values-sensitive: YES)
2. Which quadrant? (STR/OPS/TAC/SYS/STO)
3. What's the AI role vs. human role?
### Te Tiriti Approach
**Strategic baseline, not dominant overlay:**
- Respect indigenous data sovereignty principles
- Use published standards (CARE Principles)
- No direct engagement until post-launch
- No tokenism

---
## Contact & Decisions
**Human Approval Required For:**
- Architectural changes
- Database schema modifications
- Security implementations
- Third-party integrations
- Values-sensitive content
- Cost-incurring services
**If Uncertain:**
- Check TRA-VAL-0001 for values alignment

---
**Ready to Continue:** System verified, context loaded, next steps clear.
**Start with:** Verify environment → Read CLAUDE.md → Begin API routes
**End Goal:** Complete backend foundation (API + migration) before frontend development

- Blog routes
- Admin routes
- Authentication routes
- Testing endpoints
2. **Document migration pipeline** (Est: 1 day)

7. Build media inquiry triage
8. Create case study submission portal
9. Build resource directory
10. Create human oversight dashboard
### Lower Priority
11. Implement complete testing suite
---
## 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

# 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
