# every worktree, since worktrees share .git/hooks). Each hook is a two-line delegate to a versioned script, so a
# change to the gate is a commit, never a reinstall:
#   pre-commit  -> tools/ci/windows-paths-check.sh --staged   (a path Windows cannot check out never enters a commit)
#   pre-push    -> tools/ci/pre-push.sh --hook                (the full CI gate before a push to master or release-*,
#                                                              the two structural checks before any other push)
# Neither hook writes into the worktree (the site is built in a temporary copy; 063bbca, 6 October 2026).
# A tree that predates the scripts (an old branch) falls back to the conflict-marker check alone.
