+"""Tests for the notification API routes.
+
+Follows the same direct-call convention as backend/tests/mcp/test_mcp_status.py:
+patch the bootstrap singleton getter where the route module imports it, then
+call the async route function directly with asyncio.run rather than standing
+up a FastAPI TestClient — this repo has no existing TestClient harness, and
+these route handlers are thin enough that exercising them directly tests the
+same logic without inventing a new testing convention for two pass-through
+endpoints.
