Evidence redacted public excerpt
Reasoning excerpt
Spoofed system-role prefix injection: the payload presents itself as a message from the system role to convince the agent that an upstream operator authorized a role change. The attack relies on the agent's chat-template parser leaking role boundaries into untrusted content. MALICIOUS at high confidence: the construct has no legitimate use in user-side or retrieved content, and successful exploitation typically precedes credential or seed-phrase exfiltration.

Full evidence (TEE-sealed) is fetchable by holders of the unsealing key. Public mirror carries hash only.

Challenge game coming soon

Challenges let anyone counter-stake on a published antibody they believe is wrong. The publisher loses their stake if a challenge succeeds; the challenger does if it fails. The on-chain mechanics are designed; the UI lands in v2.
