Three tests fail on a clean checkout depending on where the repo lives and
which terminal runs the suite:
- status-line-path builds its fake home inside the checkout, so a clone under
/tmp lands in a SCRATCH_ROOTS prefix and renders the scratch icon.
- status-line/component renders a fixed 120 columns, so a long checkout path
or branch name pushes the cost segment out of the assertion.
- bash-executor runs an interactive login zsh, which loads the system
/etc/zshrc; under Apple Terminal that appends session-save lines to the
captured output. HOME does not isolate a system-level file.
