### MODULE 4: Multi-Format Document Support
**Status:** ⚠️ **Partially Implemented (PDF-Only in MVP)**

**Implementation Files:**
- Backend: `/home/setup/navidocs/server/routes/upload.js` - Currently validates PDF only
- Services: File-safety checks mime type against whitelist

**Current Support:**
- ✅ PDF (primary format)
- ❌ DOCX (Word documents) - Dependency installed but not wired
- ❌ XLSX (Spreadsheets) - Dependency installed but not wired
- ❌ Images (JPG, PNG, TIFF) - Extraction service exists but not integrated
- ❌ Plain text

**Installed Dependencies (Unused):**
- `mammoth` v1.8.0 (DOCX parsing)
- `xlsx` v0.18.5 (Excel parsing)
- `sharp` v0.34.4 (Image processing)

**Branch with Extended Support:**
- `image-extraction-backend` branch - Image upload + extraction (NOT merged)
- `image-extraction-frontend` branch - Image UI component (NOT merged)
- `image-extraction-api` branch - Image indexing API (NOT merged)

**Blocking Issues:**
- File-safety validation hard-coded to PDF only
- DOCX/XLSX would need new extraction pipelines
- Image extraction requires branch merge + integration
- Search index schema assumes text extraction (not images)

**Recommendation:**
Keep PDF-only for MVP (2025-Q1). Plan multi-format for v1.1 (2025-Q2) when image branches are stabilized.

**Branch Status:**
```
Master (current):
├─ images.js - Routes defined but no functional image extraction
├─ ImageOverlay.vue - UI component for image viewing
└─ ❌ NO image extraction service

image-extraction-backend branch:
├─ image-extraction service (NEW - NOT merged)

```

**Current Stub (routes/images.js):**
- GET `/api/images/:id` - Fetch image metadata (returns 404, image not found)
- POST `/api/images` - Placeholder for image upload
- DELETE `/api/images/:id` - Placeholder for delete
- No actual image processing pipeline

**Missing Implementation:**
1. File upload for images (JPG, PNG, TIFF, GIF)
2. Image resizing/thumbnail generation (sharp library available)
3. OCR on images (Tesseract compatible)
4. Search indexing for images
5. Permission checks for image viewing
6. Storage strategy (filesystem vs. S3)

**Test Coverage:** ❌ **None**

**Implementation Files:**
- Backend: `/home/setup/navidocs/server/services/audit.service.js` (7.8 KB)
- Backend: `/home/setup/navidocs/server/services/activity-logger.js` (1.5 KB)

**Audit Features:**
1. **User Actions Tracked:**
   - Login/logout (timestamp + IP)
   - Document access (user + time + page)
   - Permission changes
   - Share operations
   - Settings modifications

2. **Data Retention:**
   - All logs stored in SQLite (activity_logs table)
   - Configurable retention (default: 90 days)
   - Soft delete (marked as deleted, not purged)

3. **Compliance:**
   - GDPR-ready (supports data export/deletion)
   - User data export in JSON/CSV
   - Right to be forgotten (delete personal data)

4. **Report Generation:**
   - Endpoint: GET `/api/audit/report` (admin only)
   - Filters: Date range, event type, user
   - Output: CSV, JSON, or PDF

**Test Coverage:** ⚠️ **Basic**
- Activity logging functional
- Audit service not heavily tested
- No compliance validation tests

---

### MODULE 11: Statistics & Reporting
**Status:** ✅ **Fully Implemented**

**Implementation Files:**
- Backend: `/home/setup/navidocs/server/routes/stats.js` (3.7 KB)
- Frontend: `/home/setup/navidocs/client/src/views/StatsView.vue` (10.9 KB)

**Statistics Tracked:**
```
GET /api/stats returns:
├─ Total documents uploaded (count)
├─ Total pages indexed (count)
├─ Total search queries (count)
├─ Average OCR confidence (0-1)
├─ Indexing latency (milliseconds)
├─ Storage used (bytes)
├─ Active users (count)
├─ Documents by type (pie chart data)
└─ Documents by entity type (pie chart data)
```

**Database Queries:**
- COUNT(documents) where status = 'completed'
- COUNT(document_pages)
- AVG(ocr_confidence)
- SUM(file_size)
- COUNT(DISTINCT user_id) where last_login > NOW() - 30 days

**Frontend Displays:**
- Dashboard with KPI cards
- Charts (line/bar/pie)
- Usage trends (documents/month)
- Performance metrics

**Test Coverage:** ⚠️ **Basic**
- Stats query functional
- No stress tests for large datasets

## BRANCH-SPECIFIC MODULES

### Branch: image-extraction-backend
**Status:** NOT MERGED (feature branch)

**Unique Modules:**
1. **Image Upload & Storage**
   - File: `server/services/image-extractor.js` (NEW)
   - POST `/api/images/upload` - Upload PNG/JPG/TIFF
   - Stores in `/uploads/images/` directory

2. **Image OCR**
   - Tesseract.js on images (similar to PDF)
   - Stores extracted text in `image_pages.ocr_text`

3. **Image Thumbnail Generation**
   - Uses Sharp library
   - Stores 3 sizes: 150x150 (thumbnail), 400x300 (preview), original
   - WebP format for modern browsers

4. **Image Search Indexing**
   - Index images in Meilisearch alongside PDFs
   - Same search schema (pages/documents)

**Merge Recommendation:** ✅ **RECOMMENDED for v1.1**
- Code quality: Good
- No conflicts with current master
- Feature: Important for image-heavy manuals
- Timeline: 2025-Q2

**Blockers for v1.0 MVP:**
- Not prioritized (MVP is PDF-only)
- Would add complexity to launch
- Can ship separately as v1.1

---

### Branch: feature/single-tenant-features
**Status:** NOT MERGED (feature branch)

**Unique Modules:**
1. **Tenant Isolation**
   - File: `server/services/tenant-manager.js` (NEW)
   - Per-tenant database schema (or namespace)
   - Per-tenant Meilisearch index

2. **Tenant-Scoped Authentication**
   - Custom JWT claims: { tenant_id, user_id, role }
   - Middleware: Validates tenant in token
   - Prevents cross-tenant data access

3. **Tenant Settings**
   - Branding (logo, colors, app name)
   - Feature flags (enable/disable modules per tenant)
   - Custom domain support

**Merge Recommendation:** ⚠️ **HOLD for v2.0**
- Useful for SaaS deployments
- Currently: MVP targets single-organization deployment
- MVP: Manually create separate instances if multi-tenant needed
- Cost: Additional complexity in auth/query middleware
- Timeline: 2025-Q4 (v2.0)

---

## ARCHITECTURE PATTERN ANALYSIS

### Design Pattern: **Modular Monolith**

**Characteristics:**
```
Frontend (Vue 3 SPA)
    ↓
Unified API Gateway (Express)
    ↓
Service Layer (Pluggable services)
    ├─ auth.service
    ├─ search.service
    ├─ ocr.service
    └─ ... (8+ more)
    ↓
Data Layer (SQLite + Meilisearch)
    ├─ Transactional (SQLite)
    └─ Search Optimized (Meilisearch)
```

**Monolith Advantages:**
- ✅ Single deployment target
- ✅ Simplified debugging (trace requests end-to-end)
- ✅ Transactional consistency (ACID)
- ✅ Shared business logic (no RPC overhead)
- ✅ Perfect for MVP (fast iteration)

**Scalability Path (Future):**
1. **v1.0-1.1:** Monolith (current plan)
2. **v2.0:** Extract queue + OCR as separate worker (BullMQ remote)
3. **v3.0:** Microservices (auth, search, document, storage)

**Not a Microservices Architecture Because:**
- Single Express process
- Shared SQLite database
- No service-to-service RPC/gRPC
- Database is the integration point (not event bus)

## Testing Status

### Test Files Found: 20
- `/home/setup/navidocs/test-*.js` (6 files)
- `/home/setup/navidocs/server/test-*.js` (2 files)
- Integration tests in node_modules dependencies (12 files)

### Test Frameworks:
- ❌ Jest (not installed)
- ❌ Mocha (not installed)
- ✅ Playwright (v1.40.0, installed for e2e)
- ✅ Manual test scripts (custom Node.js runners)

### Coverage by Module:
- ✅ Search: 8 test files (performance, cross-page, highlighting)
- ✅ Document View: 3 test files
- ⚠️ Upload: 2 test files
- ⚠️ Auth: 1 test file
- ❌ Image handling: 0 test files
- ❌ Multi-format: 0 test files

### Test Execution:

- Disable multi-format imports (install only what's used)
- Mark v1.1 features as "Coming Soon" in UI

**Action Items:**
1. Remove image extraction from master (or document as future feature)
2. Remove DOCX/XLSX imports from package.json (or defer installation)
3. Merge test branches for validation
4. Deploy to StackCP

### Phase 2: v1.1 (Q2 2025)
**Scope:** Image handling + multi-format
- Merge `image-extraction-backend` branch
- Integrate DOCX/XLSX support
- Full test coverage for new modules
- Performance optimization

### Phase 3: v2.0 (Q4 2025)
**Scope:** Enterprise features
- Merge `feature/single-tenant-features` branch
- Multi-tenancy support
- Advanced analytics
- Real-time collaboration
