mrwulf 6120f9bb17 Add scalar-layer foundation (Scalar52 arithmetic mod ℓ) ... Transpile the Scalar52 limb backend (backend::serial::u64::scalar add/sub/mul/square/montgomery_*) from Rust to Lean via Charon/Aeneas, scoped at the function level to the iterator-free arithmetic core. - verification/extract-scalar.sh: function-level Charon/Aeneas extraction - verification/gen/CurveScalar/{Types,Funs}.lean: transpiled model (27 defs). This fork (v4.1.2) implements Scalar52::sub's constant-time conditional add with a pure arithmetic mask (constants::L[i] & underflow_mask), so the extraction pulls in NO external functions or types (unlike v5 dalek, which routes sub through subtle, and v4.1.3, which uses a local black_box). - verification/gen/CurveScalar/{TypesExternal,FunsExternal}.lean: decl-free stub modules kept so the check manifest is uniform across forks. - verification/Proofs/ScalarDenote.lean: semantic foundation — Scalar52 denotation into ℤ/ℓℤ, limb-bound invariant, and L_val (the transpiled constants::L denotes exactly the group order ℓ, kernel-checked). - verification/check-scalar.sh: guarded compile of the gen modules plus the denotation foundation. check-scalar.sh passes: gen compiles; denotation + L = ℓ proven. add/sub/mul remain in progress.
