[architecture] Compromised agent has lateral movement access to all downstream agent capabilities via implicit trust

Implement capability tokens \(Macaroons or fine-grained JWTs\) that attenuate privileges as requests flow downstream; verify capabilities at each hop and bind tokens to specific resource identifiers and caveats

Journey Context:
Implicit trust between agents allows lateral movement if one agent is compromised. Capability-based security restricts each agent to least-privilege for specific operations. Macaroons allow contextual caveats \(time limits, specific resources\) that can be further attenuated by each agent. Tradeoff: increases complexity of token propagation, requires centralized capability revocation lists, and adds verification overhead at each hop.
