mrwulf 55a688858c verification: pin the whole declaration surface (P1-b)
Phase 2b asks the kernel whether any AXIOM is declared under Proofs/. Phase 3
pins the cones of the named certificates. Between them sat every other
declaration in the corpus — around three thousand of them — and a helper lemma
quietly acquiring a hash oracle in its cone moved nothing either phase looked
at.

Phase 2c closes that. Ported from ltl-accumulator-verified, where a nine-attack
self-test proved a source-regex enumerator evadable by attributed, private,
indented and `instance` declarations and by a nested-namespace basename
collision. Reading the compiled environment sees what the kernel saw; no name
shape hides. Every constant contributes module, name, kind and full axiom cone,
and the observed set must equal inventory-allowlist.txt exactly in BOTH
directions, with a count trailer so a truncated run cannot pass as an empty
diff.

FOUR THINGS THIS BUILD GOT WRONG, each caught by a check rather than by review:

  - The number of inventory drivers is a per-repo FACT, not an assumption.
    dalek and anza cannot import their corpus as one environment (Proofs.Basic
    and Proofs.ConstSpecs both declare CurveFieldProofs.zero_spec); risc0 and
    betrusted have no Proofs.Basic at all. Determined by compiling a probe.
    check.sh now DISCOVERS its drivers from the filesystem instead of naming
    two, and the generator refuses to split out a module the repo lacks.

  - The split let one real declaration hide behind another's entry. Keyed on
    name alone, the two zero_specs produced byte-identical records, so 3022
    declarations were covered by 3021 allowlist entries. Caught by the count
    trailer. Every record now carries its originating module.

  - The gate's success line said "single sanctioned axiom", inherited from the
    accumulator's policy. This corpus permits NONE. A success message
    describing a different rule is how an assertion stops meaning anything.

  - selftest-axgate.sh lifted Phase 2b with a range ending at "Phase 3", so
    inserting Phase 2c between them made it swallow the new phase and die on
    variables only check.sh defines — surfacing as the BASELINE case failing,
    a self-test blaming a gate for its own extraction bug. Both self-tests now
    stop at the next phase marker whatever it is called, and refuse to run if
    they capture more than one phase. The guard is the fix; the range was the
    symptom.

WHAT THIS IS NOT, recorded in TRUSTED-BASE.md at the same length as the claim:

  - No independent cone walker. The accumulator cross-checks collectAxioms
    against a hand-written walker. Ported here it was wrong in BOTH directions
    on mathlib's inductive shapes: EdPoint gave [] against the kernel's three
    axioms, and once extended, ProjPoint gave three against the kernel's none.
    Two implementations disagreeing both ways are a second wrong answer, not a
    check. These cones rest on collectAxioms alone.

  - Thirteen Proofs/Scalar* modules are inventoried by nothing — the
    second-button seam, still open. Phase 2c names every uncovered module on
    every run so the omission is visible rather than inferred.

selftest-inventory.sh exercises the shipping gate with six cases, each
asserting a specific diagnostic, including the one that matters: a cone
widened by one oracle while name, module and kind stay put. Negative-tested by
disabling the gate's diff, which turns two cases red including one for the
wrong reason, correctly reported as such.

Verified green: 20 runs across the four repositories (four buttons, four
harness, four inventory, four axgate, four binding self-tests), zero red. The
four check-scalar.sh greens from the preceding sweep stand: that script neither
reads the pin file nor changed.

Proofs/InventoryBasic.lean — environment-derived declaration inventory (Proofs.Basic only).
Audit INFRASTRUCTURE, not corpus: excluded from check.sh's compile manifest
and from its own inventory (its constants live in modules the corpus list
below does not name). It proves nothing and is imported by nothing.
Proofs.Basic is compiled by check.sh but imported by no other module,
and deliberately reuses `CurveFieldProofs.zero_spec`, which
Proofs.ConstSpecs also declares. Importing both at once is an
elaboration error, so Basic is inventoried separately and check.sh
concatenates the two outputs before gating.
