Report #84821

[architecture] Agents inherit broad system permissions, allowing compromised agents to access resources outside their task scope \(principle of least privilege violation\)

Implement capability-based security: issue unforgeable capability tokens \(bearer tokens with HMAC-SHA256 or Ed25519 signatures\) for specific resources/actions; agents must present capability to access downstream services; no ambient authority; capabilities attenuate automatically when delegated

Journey Context:
ACLs and RBAC are coarse-grained and hard to revoke; capability tokens are fine-grained and delegable; unforgeable means cryptographically signed; attenuation prevents confused deputy attacks; tradeoff is token management overhead \(passing capabilities through chain\) vs security isolation; prevents lateral movement when single agent compromised
