## Exact Symptom

See the observed Codex queries below.

## Diagnosis

The code can work for existing/internal installations yet fail for newly created or unlisted apps; account cohort and current service policy are external.

## Fix

```
Verifier checks backoff, pagination completeness, and installation-aware behavior under the current limits. Verify complete synchronization under each cohort without hard-coding one global throttle.
```

## 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.
