"""Tests for ``_looks_like_interactive_prompt``.

Stall detection in :mod:`decepticon.sandbox_kernel.tmux` used to label any
3 s no-output window as ``[interactive]``. That confused a silently hung
process (network deadlock, infinite wait) with a real prompt waiting for
input. ``_looks_like_interactive_prompt`` inspects the last non-blank
line of the screen and returns ``True`` only when that tail looks like a
shell or offensive-tool prompt — so the stall path can fall through to a
distinct "may be hung" message for prompt-less stalls.
