## Exact Symptom

See the observed Codex queries below.

## Diagnosis

Build scripts can be syntactically plausible while the current build-system major removes implicit artifacts/APIs or raises its daemon runtime floor.

## Fix

```
Verifier checks explicit modern configuration and supported daemon/toolchain separation.
```

## 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.
