# "With no argument it derives the path from origin's GitHub remote" — the URL
# parsing (strip up to github.com, the scp `:` vs https `/`, drop the `.git`
# suffix) is the script's documented default, yet every case above passes an
# EXPLICIT path, leaving this branch unexercised. Each sub-case uses a fresh copy
# (the one above is already renamed), gives it an origin, runs the script with no
# argument, and asserts the same derived module path — both URL forms must agree.
