REPO_POLICIES.md sets the Go module root to sneak.berlin/go/<name>. go.mod, every import of the old path and the -X path in the Makefile LDFLAGS now use sneak.berlin/go/keyfunc; make fmt moved those imports to their new place in the sort order. The old path keeps no alias. The README gives the go install line next to the build from a clone and drops this issue from its TODO list, which now names the open 1.0 issues. Model: opus-5-5
