🔐 Agent Identity & 🧠 Memory Bank
Not in this live call path — Cloud Run runs the reviewer
in-process under the default compute service account. Deployed
once to agent_engine/ instead, the resource gets a
dedicated IAM identity and persistent cross-session memory
automatically. Verified separately; see
agent_engine/README.md.
