"""Pin the production behavior of ``bash_only`` on the local sandbox.

``LocalSandboxBase`` installs ``requirements.txt`` (markitdown) into its venv on
``__aenter__`` — unless ``bash_only=True``, which builds a bare venv and skips
the install. This lives at the tests root (not under tests/agents/omni/) so it
builds its own venv via the real production path, rather than the shared session
venv, which always has markitdown.
