Report #23864

[architecture] Hardcoded API keys and long-lived credentials leak when agent pods are compromised

Replace static API keys with short-lived SPIFFE Verifiable Identity Documents \(SVIDs\) issued by SPIRE; enforce mutual TLS \(mTLS\) between agents with identity-based authorization policies.

Journey Context:
Multi-agent systems often pass secrets via environment variables or config files, violating zero-trust principles. When a Kubernetes pod running an agent is compromised, attackers harvest these long-lived keys to impersonate the agent. SPIFFE provides cryptographic identities that rotate automatically \(often hourly\) and are bound to the workload's runtime identity. Combined with mTLS, this ensures that even if network traffic is sniffed, it cannot be replayed, and even if a pod is compromised, the stolen credentials expire quickly. Tradeoff: requires deploying SPIRE servers and sidecars, adding operational complexity, but eliminates secret rotation toil and prevents lateral movement in agent swarms.
