At 21:43 UK a merge on the box mirror (e1f7113f, site-land-dn3) resolved its conflict in tools/ci/pre-push.sh by taking an old copy: 88 lines gone, among them the hook's CI rule (master_ci_ok, the remote and exception logic), the branch red line, the overlap wall clock and the self-tests of the timeouts check, retry-once, ci-state, the public ledger and the gh-account check; every landing for 40 minutes ran the weaker gate and nothing said so. This commit restores the file (the one real addition of the other side, the inline-rm check, kept) and adds tools/ci/gate-manifest-check.sh in the never-push set: every push on every branch, and the merge's own push, compares pre-push.sh's run lines with tools/ci/checks.txt both ways; known-failed first (a dropped check and an unlisted check each red and named). Adding or removing a check edits checks.txt in the same commit; --write regenerates it.
