# Parity Matrix

| Behavior | Spec | Test | Implementation | Verified | Notes |
| --- | --- | --- | --- | --- | --- |
| Startup behavior | draft | -- | -- | -- | Add verification fixture |
| Error handling | draft | -- | -- | -- | Add verification fixture |
| State persistence | draft | -- | -- | -- | Add verification fixture |

- `--` means not started.
- `draft` means the stage has partial coverage and still needs review.
- `complete` means the stage is ready for the next handoff.
- `PASS` or `FAIL` apply only to the `Verified` column after implementation-side checks.
