Phase 1's anti-smuggling check reads source text. Measured today on Lean
v4.30.0-rc2, four distinct declarations compile cleanly and slip past its
anchored pattern:
` axiom cheat : ...` one leading space
`@[simp] axiom cheat : ...` line starts with the attribute
`unsafe axiom cheat : ...` `unsafe` absent from the modifier list
`axiom` <newline> ` cheat` no space follows the keyword
Any of them yields a repository that proves False while the button prints
ALL GREEN. Only the tab variant is blocked, and by Lean, not by us.
Hardening the pattern would fix the exhibited syntax rather than the class,
which is the mistake this estate has made before. Phase 2b stops parsing text
and asks the kernel instead: it reads every compiled Proofs/*.olean with
readModuleData and rejects any declaration that is an axiom.
Design notes:
- reads compiled artifacts rather than importing the modules, because
Proofs.Basic and Proofs.ConstSpecs deliberately reuse `zero_spec` and a
whole-corpus import is impossible by construction;
- membership is self-deriving from the filesystem, so Scalar* and
AxiomCheck are covered too — both are skipped by the CERTS audit and by
the dead-file gate;
- fails closed on absence: a missing .olean would make the scan vacuous, so
the count of compiled modules must equal the count of shipped sources;
- removes its temp source AND artifact on both paths, since a bare `rm`
after the call never runs under `set -e` when the gate goes red — exactly
how this repo accumulated 101 orphan .olean files;
- ~3 s for the whole corpus, against ~53 s for one module-importing run.
Phase 1's grep stays as a fast first line of defence. Phase 2b is the gate
that is load-bearing.
selftest-axgate.sh attacks the shipping gate, lifted out of check.sh at run
time rather than copied. It asserts the specific diagnostic, so a rejection
for an unrelated reason fails too, and it was itself negative-tested: with
the gate's throwError removed, the self-test goes red on exactly that case.
No proof, statement, specification or certificate is touched. No attested
commit is altered — the log binds specific commit hashes, all of which remain
ancestors of HEAD.
