The gate used to require every Validate run on the tag SHA to be green:
a cancelled duplicate or a red flake that a later re-run had fixed kept
the stable release blocked (v1.73.0, 09.09 — released by hand). Now the
verdict comes from the newest run that was not cancelled: not completed →
wait, success → pass, anything else → fail, no run → wait. The same rule
is documented for the perf workflow and the release runbook.
