- Replace MSM(curve string, ...) with MSM(curve Curve, ...). Curve enum values (0..3) match GPUKIT_CURVE_* in luxcpp/crypto so the cgo bridge forwards them unchanged. - Drop the always-error msmCPU stub; route through gpukit_multi_pippenger_cpu via cgo when -tags=lux_crypto_native is set (CPU body is the same signed-digit Bos-Coster Pippenger that backs secp256k1 / bn254 / banderwagon). - !cgo or !lux_crypto_native build returns ErrUnsupported so callers fall back to their own MSM (e.g. gnark-crypto MultiExp inside the EIP-2537 bls12381 precompile). Closes the audit hole at luxfi/precompile a5c7257e718ca0d94: MSM on BLS12-381 G1 now has a real CPU implementation through accel. Wire format (per Curve doc): CurveSecp256k1, CurveBN254, CurveBanderwagon : 64-byte BE x||y per point CurveBLS12_381 : 96-byte BE x||y per point scalars : 32-byte LE canonical
