From d9f4105577c74dedfce9b898f2180e767b6780b7 Mon Sep 17 00:00:00 2001 From: hyperpolymath Date: Fri, 25 Sep 2026 20:11:04 +0000 Subject: [PATCH] fix: resolve estate gates and Rust/Creusot debt (#87) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - docs: restore docs/src/*.md for Documenter — pages in docs/make.jl reference index.md/api-*.md but only index.adoc/api-*.adoc existed since f1b44a3 (Markdown→AsciiDoc migration). This broke the Documentation workflow for 50+ consecutive runs (every push since 2026-08-26). Restore the Markdown sources from f1b44a3^ so makedocs(prettyurls, doctest) can find its pages; keep the .adoc siblings for the berrywiki side. - chore(pkg): add GNU Guix primary packaging (guix.scm, manifest.scm) and sealed-container escape hatch (Containerfile, wolfi-base, RUN). Satisfies hyperpolymath/standards scripts/check-package-policy.sh (Guix primary / Nix fallback policy, RULED 2026-05-18). Fixes the Governance 'Guix primary / Nix fallback policy' failure that has red every push on main (e.g. run 36181334432). guix.scm pins julia/zig/rust/openssl/pkg-config and uses mpl2.0; Containerfile is Podman-verifiable where Guix is not installable. - chore(init): fill {{PROJECT_UNIQUE_STRENGTH}} in .machine_readable/bot_directives/methodology.a2ml ('Provably correct ML — Julia shape verification + Zig SIMD + Idris2 ABI + hybrid PQ signing') and delete REQUIRES_INITIALISATION.adoc. The placeholder was the only open token. - feat(crypto): reconcile Rust crypto component with Creusot (#87) Inventory docs/CRYPTO-CREUSOT-VERIFICATION.adoc, add optional creusot-contracts (feature 'creusot', cfg(creusot) shim), annotate all 6 FFI exports + 6 length getters with #[cfg_attr(creusot, ensures(...))] status-code/length contracts, add #[cfg(creusot)] mod creusot_hybrid_spec with hybrid_valid predicate (Ed448 && Dilithium5). Normal cargo build/test stays hermetic (cfg_attr discarded, no Why3 needed); cargo check --features creusot typechecks contracts. Preserves Zig FFI (zig/, ffi/zig/) and Idris2 ABI (axiom-abi.ipkg, ffi/idris/) untouched — git diff --stat origin/main shows no edits there. Update CI and provide executable evidence via .github/workflows/creusot.yml and scripts/creusot-evidence.sh (emits build/creusot_evidence.json, cargo check gate + why3 best-effort, zig/idris2 preservation check). - feat(ci): add Justfile recipes verify-crypto / creusot-evidence. Fixes #87. Governance and Documentation should now be green on main.
