Round-6 NEW-12: the header claimed 'the single external type is a core-library error type introduced by u32::try_from', but de-plumbing deleted that declaration and the file defines nothing at all; the Aeneas 'rename this template and fill the holes' boilerplate had also never been removed. Both corrected. Comment-only, so the audit digest is unchanged (d83e297a…); the Phase-0 model pin rotates 37958beb -> 2988c04c. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

"_comment": "Single machine-readable pin set to reproduce the extracted Lean model in gen/SlhVerify from source. External review rounds 2-5 (2026-07-24 .. 2026-07-27). Running verification/extract.sh against the pinned source tree with the pinned Charon/Aeneas toolchain reproduces the two aeneas-generated files byte-identically (generated_artifacts_sha256 below). The *External*.lean files are hand-maintained (not regenerated) and are NOT part of that reproducibility claim \u2014 but they ARE byte-pinned for integrity in model_integrity_sha256, since they carry the five oracle axioms and the discharged Step definitions. NOTE: SlhVerify.llbc is an intermediate artifact and is .gitignored, so its hash here can only be checked by a party who re-runs extract.sh.",

Both are sha256-pinned by Phase 0, so tampering with either is a build failure rather than a silent green, and any legitimate change is a reviewable pin rotation.
