+/**
+ * End-to-end coverage for the notifications queue health surface.
+ *
+ * The worker itself is exercised in unit tests with the queue payload pinned
+ * to a controlled shape — the server side cannot deterministically inject a
+ * Notification onto the live queue without an admin endpoint, so this suite
+ * validates the public health contract that ops and KEDA scale on:
+ *
+ *   - GET /v1/health/queue/notifications returns the live queue depth
+ *   - the threshold guard returns 503 when the depth exceeds the budget
+ *   - the failed-jobs surface accepts the notifications queue name
+ *
+ * Dedup, per-channel dispatch, and webhook signing are covered by:
+ *   - tests/unit/Platform/Workers/NotificationsTest.php
+ *   - tests/unit/Messaging/Adapter/ConsoleTest.php
+ *   - tests/unit/Messaging/Adapter/WebhookTest.php
