SUMMARY:
Completed migration from deprecated 'public: true/false' field to modern
'visibility' field across entire codebase. Ensures single source of truth
for document visibility state.
MIGRATION EXECUTION:
✓ Created migration script with dry-run support
✓ Migrated 120 documents in database (removed deprecated field)
✓ Post-migration: 0 documents with 'public' field, 127 with 'visibility'
✓ Zero data loss - all documents already had visibility set correctly
CODE CHANGES:
1. Database Migration (scripts/migrate-public-to-visibility.js):
- Created safe migration with dry-run mode
- Handles documents with both fields (cleanup)
- Post-migration verification built-in
- Execution: node scripts/migrate-public-to-visibility.js --execute
2. Document Model (src/models/Document.model.js):
- Removed 'public' field from create() method
- Updated findByQuadrant() to use visibility: 'public'
- Updated findByAudience() to use visibility: 'public'
- Updated search() to use visibility: 'public'
3. API Controller (src/controllers/documents.controller.js):
- Removed legacy filter: { public: true, visibility: { $exists: false } }
- listDocuments() now uses clean filter: visibility: 'public'
- searchDocuments() now uses clean filter: visibility: 'public'
4. Scripts Updated:
- upload-document.js: Removed public: true
- seed-architectural-safeguards-document.js: Removed public: true
- import-5-archives.js: Removed public: true
- verify-34-documents.js: Updated query filter to use visibility
- query-all-documents.js: Updated query filter to use visibility
VERIFICATION:
✓ 0 remaining 'public: true/false' usages in src/ and scripts/
✓ All documents use visibility field exclusively
✓ API queries now filter on visibility only
✓ Backward compatibility code removed
DATA MODEL:
Before: { public: true, visibility: 'public' } (redundant)
After: { visibility: 'public' } (single source of truth)
BENEFITS:
- Cleaner data model
- Single source of truth for visibility
- Simplified API logic
- Removed backward compatibility overhead
- Consistent with document security model
FRAMEWORK COMPLIANCE:
Addresses SCHEDULED_TASKS.md item "Legacy public Field Migration"
Completes Sprint 2 Medium Priority task
NEXT STEPS (Optional):
- Deploy migration to production
- Monitor for any edge cases
- Consider adding visibility to database indexes

SECURITY IMPROVEMENTS:
- Change default visibility from 'public' to 'internal' (prevents accidental exposure)
- Add visibility validation (public/internal/confidential/archived)
- Require valid category for public documents
- Add workflow_status tracking (draft/review/published)
PUBLISH WORKFLOW:
- New Document.publish(id, options) method with comprehensive validation
- New Document.unpublish(id, reason) method with audit trail
- New Document.listByWorkflowStatus(status) for workflow management
API ENDPOINTS (Admin only):
- POST /api/documents/:id/publish - Explicit publish with category validation
- POST /api/documents/:id/unpublish - Revert to internal with reason
- GET /api/documents/drafts - List unpublished documents
WORLD-CLASS UX:
- Clear validation messages with actionable guidance
- Lists available categories in error messages
- Tracks publish/unpublish history for audit trail
BACKWARD COMPATIBLE:
- Existing public documents unaffected
- Migration scripts automatically use safer defaults

**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).
