HEALTH SCORE: 9/10

Strengths

• Clean Architecture: Clear separation of concerns (routes → services → models)
• No Circular Dependencies: All imports flow unidirectional
• Complete Coverage: Every route is wired to services, every service is imported
• All Dependencies Installed: 25 production deps + 5 dev deps all present
• Database Ready: SQLite initialized with 2.0 MB of data
• Multi-Worker Support: OCR worker properly decoupled via BullMQ
• Error Handling: Global error boundaries in frontend (main.js:28-55)
• i18n Support: Vue I18n configured for multi-language
• Security: Helmet, CORS, rate limiting, JWT auth all configured

Minor Issues (-1 point)

• 7 Orphaned/Test Files in root directory should be organized
• 1 Backup File (DocumentView.vue.backup) should be removed
• Example code in /examples should be better documented or moved

Blockers

• NONE DETECTED

DEPLOYMENT READINESS

Production Build Status: READY

# Frontend production build
cd client && npm run build  # Outputs to client/dist/
# Backend startup
cd server && node index.js  # Listens on port 8001
# Worker startup
cd server && node workers/ocr-worker.js  # Processes jobs from Redis queue

Environment for Production

1. Set NODE_ENV=production in .env
2. Configure ALLOWED_ORIGINS for CORS
3. Generate new JWT_SECRET: openssl rand -hex 32
4. Set SYSTEM_ADMIN_EMAILS
5. Configure external OCR if needed (OCR_WORKER_URL)

Database Migration Path

• Upgrade from development: Run node server/db/init.js to ensure schema
• Backup before migration: cp server/db/navidocs.db server/db/navidocs.db.backup

---

RECOMMENDED CLEANUP

Immediate Actions (Safety: Green)

1. Delete client/src/views/DocumentView.vue.backup
2. Create /test directory and move:
   • server/examples/ocr-integration.js
   • server/scripts/test-*.js
3. Create /utilities directory and move:
   • server/check-.js, server/fix-.js
   • All root-level test-*.js files

Documentation

1. Add README to /server/scripts documenting one-off utilities
2. Document OCR worker startup in DEPLOYMENT.md
3. Add troubleshooting section for Redis/Meilisearch connection issues
