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.

|
|
# src/chain.cpp the block wire, the request id, the Merkle root over a
|
|
# request's records, and the three rules this chain has
|
|
#
|
|
# The two reused files are chain-neutral — Go's decoder and the cb58 alphabet
|
|
# know nothing about F — and they have already been held against the Go
|
|
# reference by the F-chain's own rows in this same differential, which is the
|
|
# whole reason to reach for them instead of writing a second opinion about what
|
|
# encoding/json accepts. That they still sit under the F-chain's name is a
|
|
# naming debt, not a dependency: the right home is a shared one and moving them
|
|
# is a rename across fifteen of that chain's files.

|
|
# NOTHING ELSE IS LINKED. No ZAP, no post-quantum library, no external
|
|
# checkout: the O-chain's wire is JSON and its only primitive is SHA-256, so
|
|
# this target builds from this tree alone.
