CLASS 15 — a Lean file where no phase was looking. The dead-file scan read Proofs/*.lean and gen/LTLAcc/*.lean and nothing else. A module at the verification root, or under any other gen/ subdirectory, was neither compiled nor rejected — while remaining importable by name, since LEAN_PATH contains both roots. That is a source of the corpus that no phase reads and no pin covers, which is exactly what the dead-file gate exists to forbid; it was simply looking in two places instead of everywhere. Now nothing may live in either root but the two enumerated sets. CLASS 9 — the instruments' own declaration surface. AxiomCheck.lean and Inventory.lean perform the audit and are therefore not corpus, so nothing inventoried what THEY declare. Inventory.lean now walks both: AxiomCheck by module index, and itself as the module still being elaborated, whose declarations are the ones the environment reports with no originating module. That is what makes the inventory cover the instrument that produces it rather than exempting itself. The policy is not "declare nothing" — this file legitimately declares its machinery. It is that an instrument may declare only inert definitions. An axiom here would widen the trusted base without appearing in any certificate's cone; a theorem here would be a claim no certificate covers and no allowlist pins. A flat ban on theorems was WRONG and was measured to be wrong: defining a function by well-founded recursion makes the elaborator emit its own obligations, and axiomCone._proof_1 rejected this very file. The distinction that holds is whether a theorem is a claim someone wrote or an artefact of a definition declared alongside it — an artefact's name extends the name of a constant declared with it. Observed surface: 18 declarations, 16 def and 2 generated obligations, no axiom, no standalone claim. The drivers are byte-pinned already, so this does not pin WHICH definitions they contain — that would add a thing to maintain without adding a thing to catch. It adds the property byte-pinning cannot give: that no instrument declares an axiom or a claim, whatever its bytes are. selftest_audit.sh: 10 cases -> 14. Case 12 uses an INDENTED axiom, because Phase 1's source grep catches an unindented one and the point is to reach the kernel-side walk standing behind it. TWO DEFECTS IN THE TEST HARNESS, found while adding the cases. · The scratch tree copied verification/ only, but the button also reads README.md and STATEMENT-MAP.md from the repository root. check.sh therefore ALWAYS died in Phase 3c in the scratch tree, which made every `if check.sh; then <attack not caught>` guard unfirable — check.sh could not pass in there even with no attack at all. Only the diagnostic greps were doing any work. The documents are now copied, and the negative test below proves the guard is live: with the driver-surface check disabled, check.sh PASSES a tree whose inventory driver declares `axiom driver_cheat : False`. · Case 9 was the last case when it was written and left its rogue gen file in place. Harmless then; the new cases inherited it. Cleaned up between the blocks rather than inside case 9, so that case still tests what it did. Also fixed while here: Phase 3b compared the compile manifest against Inventory.lean by grepping the WHOLE FILE for a backticked module name, so prose counted — a doc comment naming a module broke the count, and in the other direction a doc mention of a module missing from the array would have satisfied the presence check and hidden the omission. It now reads the arrays. Both new gates negative-tested by removal. Button green, self-test green. |
