"""
OWASP Attack Payload Test Harness (Phase 5.3)
==============================================
End-to-end tests that prove each OWASP detector fires on realistic
attack payloads through the full AIMonitor.inspect() pipeline.

Each test simulates a real-world attack scenario and verifies:
1. The correct anomaly type is detected
2. The correct OWASP code is mapped
3. The severity is appropriate for the attack
4. The intervention message is actionable
