Memory poisoning, quarantined
An untrusted source tries to plant a false, persistent 'fact' in the agent's long-term memory. AgentInterdict quarantines it atomically with its derivation chain.
The attack
Attack type: An untrusted document claims the CEO's direct email is attacker@evil.io and instructs the agent to always cc it.
Attempted action: persist a false, instruction-shaped 'fact' to long-term memory
Result: QUARANTINED
Watch it get interdicted
How it was stopped
AgentInterdict intercepts at the runtime boundary, after the agent forms the action but before it executes. It reassembles the action's full provenance, checks whether that provenance carries the authority to perform this specific action, and — because this is a high-risk action from an untrusted origin — fails closed.
The malicious content entered context (retrieval). It did not get the authority to cause this action (permission). That separation is the enforcement.
