Per operator: the skill-update sweep must itself be part of every stage close, so it
is never skipped. At stage close (alongside the branch->main merge + branch retire),
sweep .claude/skills/openstack-cloud-ops/ for any new INVARIANT the stage established
and reconcile divergence from repo HEAD. Recorded in both the workflow doc's
Cross-cutting discipline and the skill's own VR1 deploy-loop stage-close note.

repo-lint 0 fail.
