The repo moved to the hanzo-go org; the import path did not move with it, which is the point of a vanity path — a consumer pins hanzo.ai/lz4/v4 and never learns which org holds the git repo. The /v4 rides along unchanged. A major-version suffix is part of the MODULE path by Go's own rule and was never part of the repo name, which is why the vanity list could not express this module until repoOf learned to take the path's first segment as the repo.
