- Private file storage with collection system + temporary signed URLs
- Dashboard: resolved tickets table, stats, handler performance bar chart
- Spatie RBAC (admin/manager/staff)
- Notifications: TicketTransferred, TicketClosed (database + mail)
- Pest tests: 8 tests, 21 assertions
- Docker production-ready (Dockerfile + compose + entrypoint)
