## Data Flow: Document Upload
```
USER (Browser)
│
│ POST /api/upload
├─ multipart/form-data
└─ file (PDF, JPG, DOCX, XLSX, TXT)
│
▼
NGINX (Reverse Proxy)
│
├─ Proxy to localhost:8001
│ (long timeout for large files)
│
│
▼
EXPRESS ROUTE: /api/upload
│
├─ 1. AUTHENTICATE
│ ├─ Verify JWT token
│ └─ Get user ID + organization
│
├─ 2. VALIDATE FILE SAFETY
│ ├─ Check file size (max 50MB)
│ ├─ Check MIME type
│ ├─ Verify magic bytes (%PDF)
│ └─ Sanitize with qpdf (if available)
│
├─ 3. SAVE FILE
│ ├─ Generate UUID
│ └─ Save to ~/navidocs-data/uploads/[UUID].[ext]
│
├─ 4. CREATE DATABASE RECORD
│ ├─ INSERT into documents table
│ ├─ Set status = 'processing'
│ └─ Record metadata (user, org, filename, size)
│
├─ 5. QUEUE FOR PROCESSING
│ ├─ Add job to BullMQ/SQLite queue
│ ├─ Job type: 'process-document'
│ └─ Return job_id to user (for progress tracking)
│
└─ RESPOND TO USER
├─ 200 OK
├─ {
│ "docId": "uuid-xxx",
│ "jobId": "job-123",
│ "status": "processing",
│ "fileName": "manual.pdf"
│ }
└─ Client polls GET /api/jobs/job-123
for progress updates
BACKGROUND WORKER (OCR Processing)
│
├─ 1. DEQUEUE JOB
│ └─ Get document UUID from queue
│
├─ 2. DETERMINE FORMAT
│ ├─ PDF? → document-processor.js
│ ├─ Image? → process-image.js
│ ├─ DOCX? → process-word.js
│ ├─ XLSX? → process-excel.js
│ └─ Text? → process-text.js
│
├─ 3. EXTRACT TEXT (format-specific)
│
│ IF PDF:
│ ├─ 1. Try native text extraction (pdfjs-dist)
│ ├─ 2. If page has <50 chars, OCR that page (Tesseract)
│ ├─ 3. Combine results → full document text
│ └─ ⏱️ Result: 5 seconds (100-page PDF)
│
│ IF IMAGE:
│ ├─ 1. Resize if needed (sharp)
│ ├─ 2. OCR with Tesseract
│ └─ ⏱️ Result: 3 seconds per page

## Failure Modes & Recovery
| Failure | Impact | Recovery Time | Solution |
|---------|--------|---------------|----------|
| Server crash | All users offline | <1 min | systemd auto-restart |
| Database corruption | No uploads/searches | 5-10 min | Restore from backup |
| Disk full | Cannot upload | 5 min | Archive/delete old files |
| Meilisearch down | Search disabled | <1 min | Auto-restart, rebuild index |
| Network latency spike | Slow responses | N/A | Rate limiting kicks in |
| Memory leak | Gradual slowdown | 1-2 hours | Daily restart |
| SSL cert expired | HTTPS broken | 24-48 hours | Renewal process |

## Security Architecture
```
┌─ Layer 1: Network ──────────────────────┐
│ - HTTPS/TLS encryption │
│ - Certificate pinning (optional) │
│ - DDoS protection (StackCP) │
│ - Firewall rules │
└─────────────────────────────────────────┘
│
▼
┌─ Layer 2: Application ──────────────────┐
│ - JWT token validation │
│ - Rate limiting (100 req/15min per IP) │
│ - Input validation & sanitization │
│ - CORS policy enforcement │
│ - Security headers (Helmet.js) │
└─────────────────────────────────────────┘
│
▼
┌─ Layer 3: Data ─────────────────────────┐
│ - Database encryption (at rest) │
│ - .env secrets not in git │
│ - Password hashing (bcrypt) │
│ - File integrity checks (magic bytes) │
│ - Quarantine suspicious files │
└─────────────────────────────────────────┘
│
▼
┌─ Layer 4: Audit ────────────────────────┐
│ - Activity logging (all actions) │
│ - Request logging │
│ - Error tracking │
│ - Backup validation │
└─────────────────────────────────────────┘
```

## Monitoring Points
### Application Health
```bash
GET /health
→ {
"status": "ok",
"timestamp": 1699875600000,
"uptime": 3600
}
```
### Database Health
- Check navidocs.db file size grows over time
- Verify no corruption: `PRAGMA integrity_check`
- Monitor query performance
### Search Health
- Meilisearch health: `GET /health`
- Index size (should grow with documents)
- Search latency (<10ms expected)
### System Health
- Disk space: Keep >100 MB free
- Memory usage: Watch for leaks
- CPU usage: Should stay <50%
- Log file growth: Rotate weekly
---
## Deployment Verification Checklist

---
## Ready to Deploy?
Run:
```bash
cd /home/setup/navidocs
chmod +x deploy-stackcp.sh
./deploy-stackcp.sh production
```
Expected time: 30-45 minutes
Success rate: >95% (StackCP environment pre-verified)
Rollback time: <5 minutes (to previous git commit)
---
**This architecture supports**:
- Multi-tenant deployment (different organizations)
- Horizontal scaling (with Redis for sessions)
- Full-text search across all documents
- Activity audit trail
- Asynchronous processing
- Graceful error handling
- Production monitoring
**Document Version**: 2025-11-13
