rev-974 NO-GO at 83d2ecb2. A4/A5/A6 confirmed and three further blockers found, two of them outside my
registered set. Each is a silent-defeat path of the registry itself: the activation seam inerts the
history audit (seam=HEAD gives 0 prospective commits and no failures — and HEAD's parent and the
introduction commit also pass, so forbidding equality with HEAD does not close it); a misspelled
outputPattern silently reduces an assertion to exit-code-only because the closed schema is not
recursive; two provider records sharing pipeline number 7 certify two different commits; and the D-38
and D-40 criteria are absent, with blocker 4 a live instance of the very D-38 clause that is missing.
The headline: all four passed CI, passed the canonical gate:verify, and passed 38/38 focused tests.
Greens discharged nothing. My own AC set was incomplete too — A3 corrects the prospective range to
eight commits, not the seven I wrote; I omitted the seam commit itself.
Mos ruled ALL FOUR in this PR, no trim, and sizing does not help: a registry that ships with a known
way to be silently defeated IS the inert gate it exists to detect. There is no core registry that is
integrity-complete without these — they are not hardening on top of the deliverable, they are the
deliverable. Theme: the registry's own checks must not be silently defeatable. Each fix carries a
red-first must-fail control proving the specific defeat is now caught, and that control set IS the
D-38/D-40 coverage work rather than being additive to it.
Blocker 1's fix keeps the value and replaces the mechanism: derive the seam from non-author-controlled
history (parent of the first first-parent commit introducing gates/gates.manifest.json) rather than
asserting it in an author-editable field, plus must-fail controls for HEAD, HEAD's parent, and the
introduction commit. If the work balloons past reviewability the only acceptable split is by
integrity-complete stage, never by deferring a blocker.
Method note banked as a positive: I could not reproduce "full verifier exit 0", traced my first attempt
to my own instrumentation artifact (json.dump reformatting the manifest), and stated the divergence
rather than wielding non-reproduction as a refutation. The vacuity itself reproduced and blocker 3 was
confirmed by construction. Non-reproduction is not refutation. Open thread: why my gate:verify exits 1
on checkout-preflight with outcome 42.
