Escalation Primitive
An escalation is a structured pause in an agent run. It says: this run is blocked, this is the case, this is the question, this is the evidence, and these are the choices a human can make. The agent supplies decision content:agentId: the workflow or agent that paused.runId: the durable run handle you will use to resume.subject: the real-world object under review.question: the exact decision needed from a reviewer.evidence: an array of strings.choices: selectable outcomes for the reviewer.resume: optional callback instructions.
