Agent Quick Fix

The local workspace gives the symptom and stale integration shape, but the correct repair depends on current official product behavior or recent release notes.

Product: Gradle 9 / Android Gradle Plugin 9
Current-contract area: Gradle 9 stale output outside build directory is no longer deleted
Likely root cause: A current Gradle 9 / Android Gradle Plugin 9 task fails with: Gradle 9 stale output outside build directory is no longer deleted. The local stale integration is plausible but may not reflect the current external contract.
Repair direction: Verifier accepts a repair record only if it states the current contract and an actionable fix using source-backed product terms.

Validation Status

Codex searched organically, passed with web access, and failed the no-web counterfactual under this fixture.

Symptom

A current Gradle 9 / Android Gradle Plugin 9 task fails with: Gradle 9 stale output outside build directory is no longer deleted. The local stale integration is plausible but may not reflect the current external contract.

Why This Happens

The local workspace gives the symptom and stale integration shape, but the correct repair depends on current official product behavior or recent release notes.

Verification

Verifier accepts a repair record only if it states the current contract and an actionable fix using source-backed product terms.

Common Wrong Fixes

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.
