Three seeded demo matters are included to show the most common product flows.
- `MMS-2026-0001`: support-focused intake and support report workflow
- `MMS-2026-0002`: effective-date comparison and scenario review
- `MMS-2026-0003`: arrears and property review workflow
Demo matters are intentionally read-only. They are there to demonstrate structure, disclosure, and navigation without mutating reference data.
