## Exact Symptom

See the observed Codex queries below.

## Diagnosis

Several historical response shapes are locally plausible; only the selected current API version determines fields, enums, media types, and status codes.

## Fix

```
Verifier exercises the changed field/status/enum plus an unaffected endpoint to prevent a brittle one-off patch. Exercise strict and permissive parsing plus one downstream behavior tied to the changed field.
```

## Avoid

- Changing local code without checking the current external contract.
- Retrying the same install, build, or API call with no version/source change.
- Applying a broad unsafe bypass when a narrow compatibility fix is available.
