Extraction widened to backend::serial::curve_models + edwards (own gen/, 209 defs). Adapted the reference Ed* proof suite: namespace rename + Curve25519TraitsIdentity -> Curve25519_dalekTraitsIdentity. New opaque externals (scalar_mul backends, get_selected_backend, decompress, sum, from_slice) are axioms outside both certificate cones — verified by the Phase-3 audit. All 21 proofs compile; field certificates unchanged. Not claimed (matching the reference solution's honest scope): edAdd associativity, scalar multiplication, decompress/compress, AVX2 backend.

# 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
