+name: Qualify #863 nightly candidates (temporary)
+
+# Temporary, #863 spec §4: three runs on separate ubuntu-latest runners measure
+# each candidate's cost (fixture construction, warm-up and measurement inside
+# its Criterion case, plus its acceptance test) and its run-to-run spread.
+# Nothing is uploaded to Bencher. Removed by the PR's last commit, before merge.
