## Quick Wins (Start Here)

If you want immediate impact, do these first:

1. **Add `getVersion` endpoint** (30 min)
2. **Create `appsettings.json`** (1 hour)
3. **Add test project skeleton** (2 hours)
4. **Split MCPServer.cs** (4 hours)
5. **Create TransactionHelper** (2 hours)

These 5 items will move maturity from 7 to ~7.5 quickly.
