   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.

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.
