+"""Regression test for the task route shim (slice 2p, #4082/#4071).
+
+The backward-compat shim at ``routes/task_routes.py`` uses ``sys.modules``
+replacement so the legacy import path and the canonical ``routes.task.*``
+path resolve to the *same* module object. This is required because multiple
+tests do ``import routes.task_routes as task_routes`` followed by
+``monkeypatch.setattr(task_routes, "SessionLocal", ...)`` /
+``"get_current_user"``, and test_auth_regressions.py reads
+``task_routes.__file__`` for source introspection.
