+| Phase 2: File Security | ✅ Complete | 4/4 | Production-ready middleware with quarantine |
+| Phase 3+: Advanced | ⏳ Not Started | 0/50+ | YARA, fail2ban, Redis, monitoring, etc. |
+
+---
+
+## Recommended Next Steps (Priority Order)
+
+### Option A: Production Deployment & Testing (HIGHEST PRIORITY)
+**Time**: 30 minutes
+**Why**: Verify file security works with ClamAV daemon on production
+
+```bash
+# Deploy file security to production
+./scripts/deploy-full-project-SAFE.sh
+
+# Test on production (should be fast with daemon)
+curl -s -X POST https://agenticgovernance.digital/api/test/upload \
+  -F "file=@/tmp/test-clean.txt"
+
+# Test malware detection on production
+curl -s -X POST https://agenticgovernance.digital/api/test/upload \
+  -F "file=@/tmp/eicar.txt"
+
+# Verify quarantine on production
+ssh ... "ls -lh /var/quarantine/tractatus/"
+```
+
+**Expected Results**:
+- Clean file: <200ms response (vs 7.4s locally)
+- EICAR: Detected and quarantined
+- Quarantine metadata created correctly
+
+### Option B: Apply File Security to Real Endpoints
+**Time**: 1-2 hours
+**Why**: Protect actual user-facing upload endpoints
+
+**When needed**: Blog post attachments, media inquiry documents, case study submissions
+
+**Implementation**:
+```javascript
+// Example: Blog post image upload
+const { createSecureUpload, ALLOWED_MIME_TYPES } = require('../middleware/file-security.middleware');
+
+router.post('/blog/:id/upload-image',
+  authMiddleware,
+  adminOnly,
+  ...createSecureUpload({
+    fileType: 'media',
+    maxFileSize: 50 * 1024 * 1024,  // 50MB
+    allowedMimeTypes: ALLOWED_MIME_TYPES.media,
+    fieldName: 'image'
+  }),
+  blogController.uploadImage
+);
+```
+
+### Option C: Phase 1 Remaining Tasks
+**Time**: 3-4 hours
+**Why**: Complete Phase 1 security enhancements
+
+**Remaining Tasks**:
+- P1-2: YARA pattern matching (1.5 hours) - Custom malware rules
+- P1-3: fail2ban integration (1 hour) - Auto-block malicious IPs
+- P1-4: Redis rate limiting (1 hour) - Upgrade from in-memory
+- P1-6: Log rotation (30 minutes) - Prevent log file growth
+
+**Reference**: `docs/plans/security-implementation-roadmap.md`
+
+### Option D: Quarantine Management UI
+**Time**: 2-3 hours
+**Why**: Admin dashboard to view/manage quarantined files
+
+**Features**:
+- List quarantined files with metadata
+- View quarantine reason and threat details
+- Download quarantined files (admin only, logged)
+- Permanently delete or restore files
+- Statistics and charts
+
+---
+
+## Important Files & Locations
+
+### Code Files (Modified This Session)
+- `src/middleware/file-security.middleware.js` - 496 lines, production-ready
+- `src/routes/test.routes.js` - 118 lines, dev-only test endpoints
+- `src/routes/index.js` - Added conditional test routes
+
+### Documentation
+- `docs/testing/FILE_SECURITY_TEST_REPORT_2025-10-14.md` - Comprehensive test report

+
+### Directories
+- **Uploads**: `/tmp/tractatus-uploads/` (dev), configured via `UPLOAD_DIR`
+- **Quarantine**: `~/var/quarantine/tractatus/` (dev), `/var/quarantine/tractatus/` (prod)
+- **Security Logs**: `~/var/log/tractatus/security-audit.log`
+
+### Test Endpoints (Dev Only)

+- `GET /api/test/upload-stats` - View upload/quarantine statistics
+
+---
+
+## Known Issues & Notes
+
+### ✅ Resolved This Session
+1. **Quarantine directory permissions** - Now uses HOME-based path for dev
+2. **ClamAV daemon unavailable** - Automatic fallback to clamscan
+3. **Cross-filesystem quarantine** - Fixed EXDEV error with copyFile+unlink
+
+### ⚠️ Known Limitations
+1. **Dev environment performance** - clamscan takes 7-8 seconds (acceptable for testing)
+2. **Zero-day exploits** - Not covered yet (requires YARA rules)
+3. **Test endpoints exposed** - Only in development mode (NODE_ENV !== 'production')
+
+### 📝 Production Deployment Notes
+- ClamAV daemon is running (PID 845133, 521MB RAM, 8.7M signatures)
+- File security middleware is deployed but not yet applied to real endpoints
+- Test endpoints will not be available on production (correctly gated)
+

+
+## Context Pressure Status
+
+**Level**: HIGH (51.7%)
+**Reason**: Long conversation (45 messages)
+**Token Usage**: 36% (72k/200k) - Still plenty of budget
+**Recommendation**: This is a good breaking point for session refresh
+
+---
+
+## Optimal Next Session Startup Prompt
+
+**For Production Testing**:
+```
+Continue from file security implementation. Deploy to production and test the complete security pipeline with ClamAV daemon. Verify performance improvements (should be <200ms vs 7.4s locally) and confirm quarantine system works on production filesystem.
+```
+
+**For Phase 1 Completion**:
+```
+Continue security implementation roadmap. Complete Phase 1 remaining tasks: YARA pattern matching, fail2ban integration, Redis rate limiting, and log rotation. Reference: docs/plans/security-implementation-roadmap.md
+```
+
+**For Real Endpoint Integration**:
+```
+Apply file security middleware to production endpoints. Identify all current and planned file upload routes (blog, media, cases) and integrate the createSecureUpload() wrapper with appropriate MIME types and size limits.
+```
+
+**For Quarantine Management**:
+```
+Build admin dashboard for quarantine management. Create UI to view, download, restore, or delete quarantined files. Include statistics, threat details, and audit logging for all admin actions.
+```
+
