"""Regression tests for isolated service Protocol module import.

The ``IsolationService`` Protocol declares both a ``list`` method and a
``binds: list[BindMount] | None`` parameter annotation.  Without deferred
annotation evaluation (``from __future__ import annotations``), the class-scoped
``list`` method shadows the builtin ``list`` while the class body is evaluated,
raising ``TypeError: 'function' object is not subscriptable`` at import time.
