extract.sh now opens crate::backend::serial::scalar_mul::vartime_double_base (the other scalar_mul strategies stay opaque): non_adjacent_form (with its loops), NafLookupTable5 (from/select), the curve-model helpers and vartime_double_base::mul itself land in gen/CurveField - the same namespace as the proven edwards operations, so the coming double-and-add induction can consume EdDouble/EdAddProjNiels/EdConvert directly. Zero sorries, zero external axioms (the pinned sources carry documented compat refactors: single-assignment loop helpers, param-rooted while, always-256-iterations, index-based LE load). Full check.sh pressed fresh over the regenerated model: every existing field and group-law certificate still green and axiom-clean - the scope extension is purely additive.

# 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).

# 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
