The PATH story was wrong in an instructive way. I said a Homebrew Python is on
PATH only because of a shell-profile line; on this host /etc/paths.d/homebrew
puts /opt/homebrew/bin on every login shell's PATH, fresh accounts included.
The stub still wins, because path_helper appends /etc/paths.d/* *after*
/etc/paths and /usr/bin is in the latter. Ordering, not absence, is what makes
bare `python3` the 3.9.6 stub — which is also why the versioned `python3.14`
candidate is the one that matched during the real run, rather than the
/opt/homebrew/bin/python3 fallback I expected.
The harness header also credited install.sh with writing a PATH line into the
login shell. It does not write one. The reset argument is unaffected (such a
line would live in the deleted home either way), but the claim was untrue.
