ApprovalAction

An approval decision supplied when resuming a paused agent execution. When an agent execution pauses to request approval for an elevated action, SendMessage streams an approval request carrying interrupt identifiers. This structure carries the decision back to the service — which paused tool invocation is being resumed, the opaque interrupt identifier that resumes it, the identifier of the approval request being resolved, optional display text of the control the user chose, and the action taken (APPROVED or REJECTED) — so the service can resume the paused execution. All members are optional on the wire; service-side validation is applied against the populated subset.
