- Create Economist SubmissionTracking package correctly:
* mainArticle = full blog post content
* coverLetter = 216-word SIR— letter
* Links to blog post via blogPostId
- Archive 'Letter to The Economist' from blog posts (it's the cover letter)
- Fix date display on article cards (use published_at)
- Target publication already displaying via blue badge
Database changes:
- Make blogPostId optional in SubmissionTracking model
- Economist package ID: 68fa85ae49d4900e7f2ecd83
- Le Monde package ID: 68fa2abd2e6acd5691932150
Next: Enhanced modal with tabs, validation, export

SUMMARY:
Completed Phase 3 Task 3.4.1 - Enhanced the 27027 incident demo page
with interactive playback controls, service status visualization, and
clickable step navigation for better user engagement.
NEW FEATURES:
1. Clickable Step Navigation:
- Users can click any step to jump directly to it
- Steps highlight on hover with shadow effect
- Manual navigation shows progress panel and service status
- Disabled during auto-play to prevent conflicts
2. Playback Speed Controls:
- Three speed options: Slow (4s), Normal (2.5s), Fast (1s)
- Visual button state shows selected speed
- Speed persists during playback
- Default: Normal speed
3. Service Status Visualization:
- New panel shows active Tractatus services
- InstructionPersistence highlights on Step 6 (purple ring)
- CrossReferenceValidator highlights on Step 7 (purple ring)
- Service icons use brand colors (indigo/purple)
- Smooth opacity transitions
4. Enhanced Visual Feedback:
- Steps now reset properly when navigating backward
- Future steps return to pending state
- Hover effects on all steps
- Smooth scroll behavior
- Better state management (pending/active/complete/error)
5. Improved UX:
- Service status hidden until first interaction
- Progress panel shows after first play/click
- Reset clears all state including services
- Click handlers respect auto-play state
TECHNICAL DETAILS:
JavaScript (27027-demo.js):
- Added playbackSpeed variable and speedDelays mapping
- Enhanced initTimeline() with click handlers for navigation
- Updated playScenario() to use speed setting
- New updateServiceStatus() function for service highlighting
- Enhanced showStep() to handle forward/backward navigation
- Updated resetScenario() to clear service status
HTML (27027-demo.html):
- Added speed control buttons (Slow/Normal/Fast)
- Added service status panel with 2 services
- Service indicators use brand colors
- All controls use Tailwind utility classes
DESIGN PATTERNS:
- Brand-consistent colors (indigo-600, purple-600)
- Smooth 300ms transitions
- Responsive design maintained
- CSP compliant (no inline handlers)
IMPACT:
Users can now:
✓ Control playback speed for better comprehension
✓ Jump to specific steps for review
✓ See which Tractatus services activate at each step
✓ Understand the architectural intervention visually
This completes all Phase 3 interactive features. Demo is now
production-ready for deployment.

**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
