# One re-trigger in flight per PR. A second base re-point supersedes the first;
# the older dispatch is answering a question about a base that no longer holds.
#
# The group is partitioned by event class because a body edit arrives ~2s after
# a base re-point on the same PR: sharing one group, it cancelled the re-point
# run before its dispatch step and then skipped itself, so no guard run ever
# reached a verdict. The guard is advisory — `rollup` is the only required
# context — so its red is an operator signal, not a merge gate.
#
# The key mirrors only the `changes.base` half of the job's `if:`, not the
# same-repo conjunct. Safe because a PR's head repo is fixed at creation: a
# fork PR's runs only ever share a group with other fork runs of the same PR,
# and every one of those skips.
