• ✅ Rate limiting (100 req/15min per IP)
• ✅ Secure sessions (httpOnly, SameSite)
• ✅ Admin whitelist (Discord ID check)
• ✅ HTTPS enforcement
• ✅ Automated token cleanup

Operational

• ✅ Automated daily backups (4 AM)
• ✅ Health check endpoint
• ✅ Systemd service (auto-restart)
• ✅ Comprehensive logging
• ✅ Database maintenance (auto-cleanup)

📊 Architecture Decisions

1. Soft Gate (Option C)

Why: Maintains high conversion rates, industry standard, no friction at checkout

Alternatives Considered: Hard gate (require Discord before purchase), Hybrid (Discord optional)

2. Integrated Admin Interface (Option A)

Why: Shares Discord client, no duplication, simpler deployment

Alternatives Considered: Separate admin tool/service

3. SQLite for State

Why: Appropriate scale, persistence, no extra infrastructure

Alternatives Considered: Redis, PostgreSQL, in-memory

4. Plain Text Email

Why: Better spam filtering, simpler maintenance

Alternatives Considered: HTML email with branding

5. 4:00 AM Backup Schedule

Why: Lowest activity window, SQLite .backup command is safe during reads

Timing Rationale: 3-6 AM lowest activity, 4 AM is middle

💡 Key Learnings from Gemini

Technical

1. Soft gates work - Don't force Discord before purchase
2. Don't separate prematurely - Monoliths are good at small scale
3. SQLite is underrated - Perfect for this use case
4. Plain text email - Better deliverability than HTML
5. Rate limiting is essential - Even low-traffic apps need it

Operational

1. 4 AM backups - Middle of lowest activity window
2. SQLite .backup is safe - Can run while app is active
3. chmod 700 backups - Protect secrets in backed-up .env
4. Trust proxy matters - Required for sessions behind Nginx
5. Role hierarchy is critical - Bot role must be ABOVE subscriber roles

---

📝 Post-Deployment Tasks

Immediate (Within 24 Hours)

• Verify health check green
• Test complete OAuth flow with real subscription
• Check email delivery (inbox, not spam)
• Verify Ghost CMS updates correctly
• Confirm Discord roles assign correctly
• Test admin panel with all Trinity members

Within 1 Week

• Monitor logs for errors
• Review first backup success
• Test all subscription events (create, upgrade, downgrade, cancel)
• Document any deployment-specific notes
• Update operations manual

Ongoing

• Weekly audit log review
• Monthly backup restore test
• Quarterly dependency updates
• Update documentation as system evolves

🆘 If Something Goes Wrong

Application Won't Start

1. Check logs: sudo journalctl -u arbiter -n 100
2. Common causes: missing .env, syntax error, port in use
3. See TROUBLESHOOTING.md "Application Won't Start"

Webhooks Failing

1. Check webhook signature in Paymenter matches .env
2. Check health endpoint: /health
3. See TROUBLESHOOTING.md "Webhook signature verification failed"

Roles Not Assigning

1. Check bot role hierarchy in Discord
2. Verify role IDs in config/roles.json are correct
3. See TROUBLESHOOTING.md "Bot missing permissions"

Emergency Rollback

sudo systemctl stop arbiter
sudo systemctl disable arbiter
sudo rm /etc/nginx/sites-enabled/arbiter
sudo systemctl reload nginx

Full troubleshooting: See TROUBLESHOOTING.md
