chains/cpp/core and quantumvm asked for LUX_GPU_DIR and stopped with a fatal error when nothing set it, so the public P, X and Q builds could not configure at all for anyone outside this machine. The seam is an ABI of four symbols over a complete CPU backend, not a kernel, so it belongs beside the chains defined over it; the kernels stay private in lux-gpu/gpu and are still only ever dlopen'd. The D and F ports move with it, to lux-cpp/chains and lux-rs/chains, both public. luxfi/compute held nothing its licence did not already cover, being the same BSD-3-Clause as this repository's.
