+ * Edge-Net Relay Security Test Suite
+ * Tests for authentication, authorization, and attack vector prevention
+ *
+ * Attack Vectors Tested:
+ * 1. Task completion spoofing (completing tasks not assigned to you)
+ * 2. Replay attacks (completing same task twice)
+ * 3. Credit self-reporting (clients claiming their own credits)
+ * 4. Public key spoofing (using someone else's key)
+ * 5. Rate limiting bypass
+ * 6. Message size attacks
+ * 7. Connection flooding
