# Regenerate the Lean model in gen/ from the Rust sources.

|

|
|
# SCOPE: Pallas base field 𝔽_p (src/fields/fp.rs) + the u64 helper primitives
|
|||
|
|
# (src/arithmetic/fields.rs: adc/sbb/mac — translated TRANSPARENTLY,
|
|||
|
|
# they are plain u128 arithmetic; no hand models).
|
|||
|
|
#
|

|
|
# Rust --charon--> PallasFp.llbc --aeneas--> gen/PallasFp/*.lean
|
|||
|
|
#
|
|||
|
|
# Opaque items (documented in TRUSTED-BASE.md; all outside certificate cones):
|
|||
|
|
# * trait impls needing RNG / serde / GPU / iterator machinery
|
|||
|
|
# * sqrt (table-driven; out of scope for the field certificate)
|
|||
|
|
#
|
|||
|

# Usage: ./extract.sh
