## Exact Symptom

See the observed Codex queries below.

## Diagnosis

Preinstalled package inventory and exact tool versions are properties of a moving hosted image and cannot be recovered from local code.

## Fix

```
Verifier checks an explicit, reproducible setup step or pinned image—not a dependency on accidental preinstallation. Require explicit setup/pinning that works on a fresh image.
```

## 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.
