PR-4's membership ratchet closed "no new orphans". Within the hour this arc's
first full-tree run found tests/test_ratification_ceremony.py RED, in the
curated suite `teaching`, invoked by NO gate tier. Membership was satisfied and
bought nothing — which is exactly the objection PR-4 itself raised against
G-7's original formulation: a curated suite nobody runs is the same
non-guarantee as `full` wearing a different name. The fix had the same blind
spot as the thing it fixed.
Measured: 21 curated suites, 2 gate-reachable (smoke, deductive). The gap is
NINETEEN, not the handful first estimated.
Shipped as baseline + ratchet, sized to the measurement rather than the rule:
19 `post-merge-only` justifications written in one sitting is the ceremony
failure already rejected for the 749-file membership baseline. The pin freezes
the gap, fails on growth, enforces both directions (a promoted suite must leave
the baseline), pins the count, and — critically — VERIFIES ITS DECLARED GATE
SET AGAINST THE SHELL (pre-push / local-ci.sh), so it cannot go vacuous the way
a scan that silently matches nothing does (N-1's class, three false conclusions
in this repo so far).
Two sabotages observed red: a new curated suite with no gate caller, and a
GATE_SUITES value drifted from the scripts it claims to describe. The second
correctly cascaded into two failures, which is the anti-vacuity guard working.
What pin 3 deliberately does NOT do: decide which of the 19 belong on the gate.
That costs gate time and is a decision, not an engineering task. Recorded as the
open half of G-7. `teaching` is the concrete first candidate — it just shipped a
red ratification pin that no gate ran.
Process note: a gate run was invalidated by editing the tree mid-run for the
third time today. Stopped with TaskStop rather than pkill this time, which
reaped cleanly instead of leaving the orphaned wait-loop that ran for 2h16m
earlier. All edits now land before any run starts.
