cgo says a C compiler is available. It does not say libluxgpu_hqc and lux/gpu/hqc.h are installed. code_cpu.go declared the second fact as the first, so any consumer that turns cgo on for an unrelated reason — blst, say — had to carry a luxgpu install or fail to compile: ops/code/code_cpu.go:102:10: fatal error: lux/gpu/hqc.h: No such file or directory Two facts, two predicates. This restores the pairing ops/code carried through v1.2.4 and that every other optional native link in accel still uses: crypto_secp256k1_cgo.go and ops/crypto/crypto_msm_native.go behind lux_crypto_native, ops/fhe/cgo.go behind luxfhe, internal/capi/real.go behind lux_accel_real. ops/code was the lone file keyed on bare cgo. code_nocgo.go covers the complement, so a plain cgo build now reports ErrNativeHQCUnavailable — the error the API already documents — instead of failing to build. -tags=lux_hqc_native links the native oracle unchanged. Verified: build + test at CGO=0; CGO=1 with and without the tag; both again under -tags=accel. Full suite green.
