`which cc` will confirm: it returns `/usr/bin/cc` rather than the user's wrapper. — on Debian/Ubuntu (and any distro shipping the `cc` alternative). Tension: It lives in a system PATH entry that comes BEFORE user paths like `~/.local/bin` in many shell setups (or the wrapper directory was not added to PATH at all). Outcome: `/usr/bin/cc` is a symlink managed by `update-alternatives` pointing to gcc.
