"""Regression test for the note route shim (slice 2f, #4082/#4071).
The backward-compat shim at ``routes/note_routes.py`` uses ``sys.modules``
replacement so the legacy import path and the canonical ``routes.note.*``
path resolve to the *same* module object. This is required because
``test_note_reminder_fire_scope.py`` and ``test_notes_fail_closed_auth.py``
do ``import routes.note_routes as note_routes`` followed by
``monkeypatch.setattr(note_routes, "SessionLocal", ...)`` — for those patches
to take effect at runtime, the legacy module object and the canonical one
must be identical. This test pins that contract.
