[architecture] Agent impersonation and privilege escalation via forged identity or confused deputy attacks

Adopt Object Capabilities \(ocaps\): grant unforgeable object references \(capabilities\) instead of identity-based ACLs; agents hold only the capabilities they need, eliminating ambient authority.

Journey Context:
Traditional ACLs \(role-based\) assume 'if you have the token, you are the service'. In multi-agent systems, this leads to confused deputy problems \(Agent B uses Agent A's credentials to access Agent C\) and lateral movement on compromise. Object Capabilities \(from E-language, now in Spritely/Goblins\) bind authority to unforgeable references. Agent A passes a capability to Agent B, which cannot be replayed by Agent C. Tradeoff: requires capability-aware runtime; revocation is complex \(requires capability attenuation or revocation lists\). However, it eliminates entire classes of injection and impersonation attacks compared to bearer tokens.
