These were in luxfi/compute, a private repo whose licence is the same BSD-3-Clause as luxfi/node's. Nothing here needed protecting, and keeping it private broke the public Rust chain builds that reference it. Sibling paths lose a level: the chains sat three deep in compute and sit one deep here. The conformance generator loses a replace naming an absolute path on one machine, and takes luxfi/chains from the proxy. Co-authored-by: Hanzo Dev <[email protected]>

|
//! what the ABI crate resolved, so the directory is found exactly once, down
|
