THE SEAM. This repository is checked by two scripts, and until now neither
asserted anything about the other's scope. check.sh's dead-file gate simply
SKIPPED anything named Scalar*, so a new Proofs/ScalarX.lean was gated by
nothing at all: absent from one manifest by exemption, from the other by
omission, compiled by neither, inventoried by neither. Each button now reads
the other's manifest and requires every shipped proof source to belong to
EXACTLY ONE of them — neither orphaned nor double-claimed, both directions,
plus a phantom check on entries naming files that do not exist. Negative-tested
four ways, including the exact hole this item names.
THE SCALAR BUTTON. Closing the seam exposed it as the estate's weakest link,
having been left behind by every hardening round while the main button gained
five phases. 45 lines to 227:
- source-integrity check over its sources;
- harness-pin verification, so running THIS button alone is protected and not
only running it after check.sh;
- a kernel-side axiom-declaration gate over the compiled artifacts, replacing
a source-text grep that is evadable four ways on v4.30.0-rc2;
- a declaration inventory of ~1880 constants against its own allowlist,
diffed both directions with a count trailer. These 13 modules were the only
part of the proof corpus with no inventory: check.sh Phase 2c named them as
uncovered on every run, and now names the button that covers them instead;
- per-certificate exact-cone assertions replacing `-eq 13` over matching
output lines. A count cannot say WHICH certificate is clean and passes just
as happily if one cone is reported twice.
Every fork-specific fact was read from the existing script rather than assumed:
risc0 and betrusted audit sub_loop1_one_spec where dalek and anza audit
cond_add_l_one_spec, untouched.
THREE BUGS, ONE ROOT CAUSE, all found by the gates rather than by review. Each
reasoned about how a thing is SPELLED instead of what it BELONGS TO, and the
corpus punished each: Proofs/ScalarPackSpec.lean is named like the scalar layer
and owned by the main button.
- the scalar dead-file gate globbed Scalar* and demanded ScalarPackSpec be
scalar-owned. REMOVED rather than special-cased: the seam check tests
membership in exactly one manifest, which is strictly stronger than any
prefix;
- the scalar axiom gate scanned Scalar*.olean, reporting "14 modules" for a
13-module manifest. On a tree where check.sh had not run that artifact is
absent and the button would have failed for a false reason. It now scans
the manifest by membership and fails closed on a missing artifact;
- Phase 2c's driver discovery globbed Inventory*.lean and claimed the other
button's driver, then correctly complained its own manifest lacked those
modules.
This is the family the campaign began with: a source-text axiom grep reasoning
about spelling. Recorded in TRUSTED-BASE.md because it generalises.
Also fixed: the first negative test of the scalar gate's absence check passed
for the wrong reason — the button recompiles before the gate runs, so removing
an artifact merely caused it to be rebuilt. Retested against the lifted phase,
where absence is a persistent condition.
Verified green: 24 runs across the four repositories — four main buttons, four
scalar buttons, and sixteen self-tests — zero red.
