github.com/hanzoai/template existed only as loose files: no .git, no history, no remote. Sweeps that look for a .git directory could not see it, and an rm -rf would have destroyed it with nothing to recover from. Committed as-is; no source modified. NOTE: no remote. This is still one copy in one place.
