GitHub keeps a single pending entry per group, so a newer pending run displaces an older one and intermediate push runs still end as `cancelled` during busy periods. And the expression is evaluated against the *newly triggered* run, so a run whose own event is not `push` — a benchmark dispatched on master within `ci-master.yml`, sharing its group `CI master-` — evaluates to `true` and does cancel a drill that is mid-flight. That is a rare manual action and the next master push restores the evidence, so it does not warrant further mechanism. What the carve-out buys is that the lane periodically reaches a verdict at all, which is what makes it usable as evidence. -The decision belongs at workflow level because cancellation applies to the whole superseded run: a job-level `concurrency` group does not exempt its job. The negated form is load-bearing rather than cosmetic: naming `pull_request` alone would also stop cancelling `workflow_dispatch`, and each runner benchmark fans out to twelve larger runners for up to fifteen minutes inside this same group on master, so a re-dispatch would queue ahead of a drill instead of replacing a stale measurement. What bounds the cost is that a master push carries only `wine-apt-cache` and these two drills; every other job is pull-request-gated, `workflow_dispatch`-gated, or `if: false`, and `scripts/ci-workflow.spec.ts` pins that set — classifying by exact condition, since a negated event test mentions the event it excludes — so a new push-reachable job cannot quietly start accumulating uncancelled runs. +The decision belongs at workflow level because cancellation applies to the whole superseded run: a job-level `concurrency` group does not exempt its job.
