The module already called itself github.com/luxfi/node while containing no node in Go: cmd/luxd was twenty-one lines that printed the size of a few types, and the Go column of the matrix measured a VM plugin. A repo that fetches the thing it claims to be has not replaced it, so the Go sources move in — 1515 files, the daemon and everything under it — and the build reaches outside this module for nothing. Rust and C++ sit beside it unchanged and are still measured against it by the differential. That is the point of one repo: the reference implementation and the two ports are the same checkout, so parity is a thing you can run rather than a thing you assert. Verified: builds, and the closure carries no lux-private — checked at build time rather than believed. The daemon starts twelve chains on a local network (P X C Q Z A B G K M F, plus D through its plugin) and reports healthy.
