[architecture] Unverified Tool Execution Chains

Implement capability-based access control \(CapBAC\) for tools: each agent is granted capability tokens \(unforgeable references\) only for specific tools it needs; before executing a tool call, the agent \(or tool proxy\) validates the capability token against the requested action. Log all capability delegations in an append-only audit trail.

Journey Context:
In multi-agent systems, agents often share tool sets \(APIs, databases\). Without verification, a compromised or buggy agent can invoke tools it shouldn't have access to \(e.g., an analyst agent deleting data\). Traditional RBAC is too static; capability-based security \(from E systems\) allows dynamic, revocable delegation that matches the fluid nature of agent chains.
