The module path becomes sneak.berlin/go/keyfunc, as the repo policy sets for Go modules: go.mod, every import and the -X path in the Makefile. The old path gets no alias. The README gives a go install line for the new path, which resolves with @latest only once main carries the move, and its TODO list now names the open 1.0 issues. Model: opus-5-5
