- Consolidate all 20 API files to use centralized Database helper - Add optimistic locking to ticket updates to prevent concurrent conflicts - Add caching to StatsModel (60s TTL) for dashboard performance - Add health check endpoint (api/health.php) for monitoring - Improve rate limit cleanup with cron script and efficient DirectoryIterator - Enable rate limit response headers (X-RateLimit-*) - Add audit logging for workflow transitions - Log Discord webhook failures instead of silencing - Fix visibility check on export_tickets.php - Add database migration system with performance indexes - Fix cron recurring tickets to use assignTicket method Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
