# #14051 Tier B: label runs are pure metadata — a superseded label pass on the
# same PR/issue is worthless. Cancel the in-flight run when a new event lands so
# rapid pushes don't pile up 70+ queued Auto Label runs on the fleet. Group by
# PR number (or issue number) so PR and issue lanes never collide.
