A pull request can be conflict-free, have green CI, and still lack evidence that the final merged state was ever checked.

That is the narrow problem behind merge-proof, a small open-source Git / GitHub Action tool I just published.

This is not a claim that AI-authored code is broken. It is not a claim that GitHub CI is broken. It is not a claim that a flagged PR contains a bug.

It is only about evidence.

The strongest objection first
