🎓 Lessons Learned

What Went Well

1. Systematic Approach: Tackling scheduled tasks in priority order was highly effective
2. Automation Scripts: Creating reusable scripts for CSP cleanup saved significant time
3. Event Delegation Pattern: CSP-compliant event handling is now standardized
4. Production Deployment: Even manual deployment worked smoothly with validation
5. Quality Gates: Having clear success criteria kept focus sharp

Challenges Overcome

1. RSyncignore Issues: Deployment script had regex issues, used manual scp successfully
2. File Read Errors: Edit tool required re-reading files occasionally
3. Context Management: Large session required careful todo list management

Best Practices Confirmed

1. Always use minified CSS in production
2. Test contrast ratios programmatically (WCAG AA = 4.5:1 minimum)
3. Reserve space for dynamic content to prevent CLS
4. Use data-action attributes instead of inline event handlers
5. Maintain single source of truth for data models

🚨 Important Reminders

Before Next Session

• Review SCHEDULED_TASKS.md for updated priorities
• Check production Lighthouse scores to confirm improvements
• Ensure local dev server is running (port 9000)
• Run node scripts/session-init.js at session start

Deployment Notes

• Production uses systemd (NOT pm2)
• Service name: tractatus.service
• Manual deployment via scp works when rsync fails
• Always restart service after backend changes: sudo systemctl restart tractatus
• Validate deployment with curl + HTTP status checks

Code Quality Standards

• Zero CSP violations (enforced by pre-commit hook)
• WCAG 2.1 AA compliance (4.5:1 contrast minimum)
• World-class performance (aim for 90+ Lighthouse scores)
• No fake data, no shortcuts
• Always test production after deployment
