PR-6 promoted tests/test_safety_pack.py onto the gate and left it listed in
tests/full_only_baseline.txt. test_baseline_has_no_stale_entries failed the very
next smoke run, naming the file and the direction.
That is the both-directions half of the ratchet doing exactly the work it was
written for, roughly an hour after it landed, against the person who wrote it.
A baseline that silently keeps entries it no longer needs stops being a
measurement and becomes a story about one — so the failure is the feature.
Recorded in the pin's own docstring and in G-7, because a mechanism catching its
author is better evidence than a sabotage test: the sabotage was contrived, this
was not.
Baseline: 749 -> 748. The ratchet only turns down.

N-9 is the finding, and it PREVENTS work rather than re-scoping it.
WHAT THE PLAN GOT WRONG. N-3 concluded the 23-vs-13 smoke delta was unintended
drift, on two in-repo comments asserting parity, and called that "the strongest
evidence available that the drift was never intended". H-12 repeated it; R-14
built three options on it recommending "raise CI, +46s measured"; PR-4
specified a bidirectional parity pin as deliverable one.
A third artifact answers all of it, and none of them read it.
tests/test_cli_test_suites.py::test_cli_smoke_suite_covers_ci_smoke_gate has
pinned smoke.yml SUBSET-OF TEST_SUITES["smoke"] since before this assessment —
which is why every measurement finds CI-only == 0; a pin, not luck — beneath a
comment headed "DELIBERATELY ONE-DIRECTIONAL — do not 'complete' this by also
asserting local_paths <= ci_paths". Its history is 50fa287d (2026-07-25):
"revert(tests): drop the local-to-CI smoke parity assertion — CI is not a
gate." An earlier agent read the same comment, drew the same inference, made
the assertion symmetric, and reverted it hours later: "That was wrong, and
AGENTS.md says so in a line I had already read."
AGENTS.md:280 — GitHub is "a mirror only; its Actions are billing-locked and
produce dead signals — never chase them." §277 — the workflows are "secondary
observability only." So the local suite is the SOURCE and is deliberately
broader; the delta is the design.
- PR-4 pin 1: WITHDRAWN. It exists, in the direction that protects something.
- R-14: premise corrected in the packet. Option A spends 46s on a workflow
that does not gate; option B would delete real protection for a fiction;
option C's live half is a two-line comment fix, done here.
- N-3's exposure claim was too GENEROUS to CI: for a push that skipped the
local gate there is no automatic check at all. Larger than stated, and not
closable by editing smoke.yml.
WHAT LANDED. Measured: 749 of 877 test files are in no curated suite. The
plan's mechanism ("assign every orphan, or 749 exclusion reasons") is hollow at
that scale — glob topic-suites ("adr": tests/test_adr_*.py absorbs 172) satisfy
the assertion while changing nothing about what executes, which is precisely the
Third-Door objection the plan levels at G-7's own first formulation. All four
demonstrated incidents (#113, #136, negation-survives-articulation,
speculative-subject-lifecycle) were caused by a NEWLY LANDED orphan; none by a
legacy one.
So: a ratchet. tests/test_suite_membership.py + tests/full_only_baseline.txt.
New orphans fail. The baseline is enforced in BOTH directions — a promoted or
deleted file must leave it, so the list can only shrink — and its count is
pinned so bulk movement is a reviewed decision, in the discipline
test_volume_honesty.py uses.
Also: the gate-guarding pin now runs on the gate. test_cli_test_suites.py lived
in `fast`; the pre-push gate runs smoke + deductive. The pin guarding the gate
did not run on the gate.
Three sabotages, each OBSERVED RED: a new unregistered test file, a stale
baseline entry, the parity pin demoted out of smoke.
Note on the delta: now 12 (local 27, CI 15) because this session added three
pins locally. Under the corrected reading that is the design, not widening
drift — the invariant is CI-only == 0, and that is pinned. The registers now
say so; "ten files" was a measurement, never a target.
Process note: `git checkout --` during sabotage cleanup destroyed uncommitted
edits to core/cli_test.py, which were redone. Backups, not checkout, on files
with unstaged work.
Registers: G-7 CLOSED, H-12 amended, R-14 dissolved in the packet, PR-4
re-specified, N-9 added to plan §0.
