…uns cancel each other GitHub keeps one pending run per concurrency group, so the shared workflow/ref group let a newer push replace a queued default-branch run. Non-PR events now group by run id; PR runs still share a per-branch group and cancel the superseded run.

GitHub keeps at most one pending run per concurrency group and cancels the older pending one when another arrives, whatever
cancel-in-progresssays. The groups added in the Actions-audit PR were keyed on${{ github.workflow }}-${{ github.ref }}for every event. So with a main-branch run A in progress and B queued, a third push C cancelled B, and a scheduled CodeQL run could be replaced the same way. The comment promised default-branch results were never dropped; a queued one could be. (Found by the second-opinion review.)Now the group is
${{ github.workflow }}-${{ github.event_name == 'pull_request' && github.ref || github.run_id }}:cancel-in-progress(still true for PRs only) cancels the superseded run.Validated: every workflow in the repo parses, and actionlint 1.7.7 is clean.
stealth.ymlkeeps its per-ref queue on purpose and is unchanged.
