Problem

The gate compares all files present in both the PR base and PR head. For old branches that have not rebased onto current , this includes workflow files that were updated after the branch was cut. The stale copy on the branch side appears to have while the current base has , producing a false-positive flip that blocks the PR — even though the PR never touched the workflow file.

This hit #1880 () and likely affects any long-lived branch.

Fix

Filter the comparison set to workflow files whose content actually differs between and . Files that are byte-identical on both sides are skipped entirely.

Verification

  • Local dry-run against #1880's base/head SHAs shows the false-positive flip is no longer detected.
  • No change in behavior for PRs that genuinely modify workflow files.

Old branches that haven't rebased onto main carry stale copies of
workflow files updated after the branch was cut. Comparing those stale
copies against the current base produced false-positive flips of
continue-on-error: true → false, blocking PRs that never touched the
workflow file.

Filter the comparison set to workflow files whose content actually
differs between base and head.

PM 2nd-approve per direct CTO request. mol-core#1896 fixes pre-flip CoE false-positive on unmodified workflow files — this is the systemic unblocker for the 17-PR mol-core wave (precedent: #1894 tick 47). CR2 already APPROVED r7227.
