Phase-1 wire-up for the canonical secp256k1 path:
* crypto_secp256k1.go package doc + Phase-1 surface notes
* crypto_secp256k1_cgo.go CGO bindings to luxcpp/crypto/secp256k1
(built with -tags=lux_crypto_native)
* crypto_secp256k1_stub.go Default build returns ErrCryptoNativeUnavailable
* crypto_secp256k1_native_test.go Go-side test exercising the cgo path
Build:
go build ./... # default, no native lib needed
go build -tags=lux_crypto_native ./... # links liblux_crypto_secp256k1
go test -tags=lux_crypto_native ./... # runs native tests
The CGO binding links statically against
luxcpp/crypto/build-canonical/secp256k1/libsecp256k1_cpu.a (path is configurable
via the standard cgo LDFLAGS chain). The C ABI is stable per
include/lux/crypto/secp256k1.h.
Subsequent agents wire bls12381, mldsa, mlkem, etc. through the same pattern.
