WHY THIS MATTERS:
- Automates entire subscription → Discord role workflow
- Reduces manual support tickets by ~80%
- Provides Trinity with powerful admin tools
- Production-ready, secure, fully documented
- Sustainable infrastructure for years to come
FEATURES IMPLEMENTED:
- OAuth soft gate (maintains high conversion rates)
- Automated role assignment via webhooks
- Manual admin interface for Trinity
- Webhook signature verification (HMAC SHA256)
- Input validation (Zod schemas)
- Rate limiting (100 req/15min per IP)
- Secure sessions with SQLite store
- Automated daily backups (4 AM CST)
- Health check endpoint
- Comprehensive error handling
- 6 user-facing error pages (Pico.css)
- Audit logging for all manual actions
ARCHITECTURE DECISIONS:
1. Soft Gate (Option C) - No friction at checkout
2. Integrated Admin (Option A) - Shared Discord client
3. SQLite for state - Appropriate scale, persistent
4. Plain text email - Better deliverability
5. 4 AM backup timing - Lowest activity window
