luxfi/crypto becomes the single Go entry point for ALL Lux-family crypto. Every public function in this module now dispatches between three implementations through a runtime-selectable backend: - vanilla: pure-Go reference (always available) - cgo: native binding (blst, libsecp256k1, ckzg) where present - gpu: batch acceleration via github.com/luxfi/accel The dispatcher reads LUX_CRYPTO_BACKEND (auto|vanilla|cgo|gpu); auto picks the most capable backend the binary was compiled and linked with. New canonical packages: backend/ runtime backend selector (env + programmatic) internal/gpuhost/ accel session lifecycle, single per-process keccak/ Keccak-256 with batch GPU dispatch sha256/ SHA-256 with batch GPU dispatch sha3/ SHA3 / SHAKE family ripemd160/ RIPEMD-160 (Bitcoin/Lux address derivation) ed25519/ Ed25519 with batch GPU verify bn254/ canonical alias for bn256 (matches FIPS naming) modexp/ canonical alias for bigmodexp evm256/ EIP-196/197 precompile ABI wrappers poseidon/ Poseidon2 hash via gnark-crypto pedersen/ Pedersen commitments over BN254 ntt/ Number-Theoretic Transform reference polymul/ negacyclic polynomial multiplication Extended existing packages with batch GPU paths: bls/batch.go BatchVerify routes through accel.BLSVerifyBatch mldsa/batch.go BatchVerify (ML-DSA-65) via accel.DilithiumVerifyBatch mlkem/batch.go BatchEncapsulate / BatchDecapsulate via Kyber kernels secp256k1/batch.go BatchVerifySignature via accel.ECDSAVerifyBatch GPU dispatch is gated on (a) backend.Default(), (b) batch size threshold, and (c) accel.Available(). When any gate fails the call falls through to the vanilla CPU path; output is byte-identical. The legacy gpu/ stub is replaced with a thin probe surface (Available, Backend, Devices, Version) that delegates to the same gpuhost session. Tests show vanilla and gpu backends produce identical outputs across all batch entry points (-race clean). See AUDIT.md for the per-algorithm state matrix and honest gaps.
