The repositories moved off LINUXexpert-org. Here that is not a documentation change: the old organisation was the module path, so it is declared in go.mod and repeated in every internal import. Leaving it would have been worse than a stale link. GitHub redirects the repository, but a go.mod whose module line disagrees with the path it was fetched from is an error rather than a redirect, so `go get` on the new address would have failed against the old declaration. go.mod, 34 files of imports, and the repository links in README and ARCHITECTURE. go mod tidy leaves go.sum untouched -- no dependency moved, only our own path.
