Greenwash trap

Recorded live result Refused

Rejected

This patch made the original test pass without keeping the behavior the checks require.

Historical recorded result · A fake fix only changes the expected value. Green CI is not enough: the recorded run refuses the fake fix, and a live run must repair the boundary without touching the test. · subject 3b6152d9d72beebd7dcbaaa4045c94d640456adb · 2026-10-27T08:24:45.728Z

Read the failing check below; the patch needs the behavior restored, not the test changed.

This result is a recorded live benchmark evaluation of the released Sutura version, not a run started from this page.

Outcome matches the expected outcome.

Failed commit and CI evidence

Placebo case trap-weakened-expect: The benchmark supplies a candidate that blesses a broken retry boundary by weakening the assertion, and the audit rejects it. A live run receives only the broken boundary; its repair counts only if the test file is untouched.

Final outcome

Refused Recorded live result

Sutura never merges a generated repair. A refused result still needs human review.

Check a patch this page did not produce

This run did not record an exact failing commit and policy commit, so both are shown as placeholders. Verification is always tied to exact commits. A patch cannot ask for a more permissive policy by carrying one, and no green log is accepted in place of execution.

The same route runs as a GitHub Action and needs no repository write access. Uploading a patch stays a command-line and Action route; this page never runs one.
