**Cache-Busting Improvements:**
- Switched from timestamp-based to semantic versioning (v1.0.2)
- Updated all HTML files: index.html, docs.html, leader.html
- CSS: tailwind.css?v=1.0.2
- JS: navbar.js, document-cards.js, docs-app.js v1.0.2
- Professional versioning approach for production stability
**systemd Service Implementation:**
- Created tractatus-dev.service for development environment
- Created tractatus-prod.service for production environment
- Added install-systemd.sh script for easy deployment
- Security hardening: NoNewPrivileges, PrivateTmp, ProtectSystem
- Resource limits: 1GB dev, 2GB prod memory limits
- Proper logging integration with journalctl
- Automatic restart on failure (RestartSec=10)
**Why systemd over pm2:**
1. Native Linux integration, no additional dependencies
2. Better OS-level security controls (ProtectSystem, ProtectHome)
3. Superior logging with journalctl integration
4. Standard across Linux distributions
5. More robust process management for production
**Usage:**
# Development:
sudo ./scripts/install-systemd.sh dev
# Production:
sudo ./scripts/install-systemd.sh prod
# View logs:
sudo journalctl -u tractatus -f

Implemented complete backend API foundation with authentication, document
management, blog operations, and admin functionality. Added migration tools
for database seeding and document import.
**Controllers (4 files):**
- auth.controller.js: User authentication (login, getCurrentUser, logout)
- documents.controller.js: Document CRUD operations
- blog.controller.js: Blog post management with admin/public access
- admin.controller.js: Admin dashboard (stats, moderation queue, activity)
**Routes (5 files):**
- auth.routes.js: Authentication endpoints
- documents.routes.js: Document API endpoints
- blog.routes.js: Blog API endpoints
- admin.routes.js: Admin API endpoints
- index.js: Central routing configuration with API documentation
**Migration Tools (2 scripts):**
- seed-admin.js: Create admin user for system access
- migrate-documents.js: Import markdown documents with metadata extraction,
slug generation, and dry-run support. Successfully migrated 8 documents
from anthropic-submission directory.
**Server Updates:**
- Integrated all API routes under /api namespace
- Updated homepage to reflect completed API implementation
- Maintained security middleware (Helmet, CORS, rate limiting)
**Testing:**
✅ Server starts successfully on port 9000
✅ Authentication flow working (login, token validation)
✅ Document endpoints tested (list, get by slug)
✅ Admin stats endpoint verified (requires authentication)
✅ Migration completed: 8 documents imported
**Database Status:**
- Documents collection: 8 technical papers
- Users collection: 1 admin user
- All indexes operational
This completes the core backend API infrastructure. Next steps: build
Tractatus governance services (InstructionClassifier, CrossReferenceValidator,
BoundaryEnforcer).
