  "_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.",
