mrwulf 984d82a7d7 Merged gen: one CurveField universe (field + curve + scalar), both buttons green
Same architecture as the dalek/risc0/betrusted forks: the Scalar52
arithmetic start-froms (11 fns) plus scalar::from_bytes_mod_order[_wide]
join the CurveField extraction, so the field, curve, and scalar layers
share a single type universe - the prerequisite for the signature apex,
whose verify glue must see curve AND scalar calls resolve to proven
definitions by fully-qualified name.

Proofs/ScalarDenote.lean flips its import CurveScalar.Funs ->
CurveField.Funs (one line; the whole scalar proof chain recompiles
unchanged on the merged gen). check-scalar.sh repoints its GEN list.
gen/CurveScalar retained until the deprecation pass, as on the siblings.

check.sh + check-scalar.sh both green, all certificates axiom-clean.

# Regenerate the Lean model in gen/ from the Rust sources.
#
# SCOPE: field arithmetic + Edwards point arithmetic
# roots: crate::field, crate::backend::serial::u64::field,
# crate::backend::serial::curve_models, crate::edwards
# (same widening the reference solution used for its Tier-1 addition-law
# theorem; scalar-mul backends and decompress internals stay opaque —
# upstream Aeneas cannot translate them; they are modeled/axiomatized in
# gen/CurveField/FunsExternal.lean OUTSIDE every certificate's cone).
#
# Rust --charon--> CurveField.llbc --aeneas--> gen/CurveField/*.lean
#
# The hand-written gen/CurveField/{TypesExternal,FunsExternal}.lean are NOT
# touched by regeneration (Aeneas only rewrites the *_Template variants).
# After regenerating, diff the templates against the hand-written files:
# diff gen/CurveField/FunsExternal_Template.lean gen/CurveField/FunsExternal.lean
#
# Usage: ./extract.sh
