+Date: 2026-05-08 10:24 AM
+
+## 2.1 Test D1 to backend data flow
+- Status: Pass
+- Command: python scripts/simulate_alert.py (with KAFKA_BOOTSTRAP_SERVERS=localhost:29092, KAFKA_TOPIC_VITALS_RAW=pulse-data)

+- Result: 2 passed
+
+## 2.3 Test D2 anomaly detection flow
+- Status: Pass
+- Command: pytest tests/integration/test_worker_pipeline.py
+- Result: 2 passed
+  - alerts topic emitted an alert after simulate_alert.py --critical (verified via kafka-console-consumer).
+
+## 2.4 Test backend to D3 dashboard flow
+- Status: Pass (with auth required override)
+- Command: SOCKETIO_REQUIRE_AUTH=true pytest tests/integration/test_socket_bridge.py

+  - Keycloak admin token acquired
+  - HealthCare realm user Admin verified (email updated to admin@test.com)
+  - medicare client verified
+  - /api/auth/callback with dummy code returns 500 (expected)

+  - d2_alerts_delivered_total
+  - d2_alerts_acknowledged_total
+
+## 2.8 Test Grafana dashboard
