Report #24225

[architecture] Agent impersonation and privilege escalation via prompt injection

Replace identity-based authentication with object capabilities \(ocaps\): pass unforgeable capability tokens \(UUIDs cryptographically tied to specific permissions\) rather than bearer tokens or identity strings.

Journey Context:
Identity-based auth \(API keys, JWTs\) fails when Agent B is tricked via prompt injection into executing a command purportedly from Agent A. Capabilities are unforgeable references that grant specific rights; possessing the capability is the proof of authorization, preventing privilege escalation even if identity is spoofed through injection.
