List conversation handoffs

Use to investigate escalation reasons, captured/missing handoff fields, notification events and handoff/review resolutions for one conversation. Discover conversationId with list_conversations. Action execution receipts are separate in list_action_executions. Requires conversations:read. Returns a paginated combined window of handoff and review cases: default/max 30 total cases, ordered by creation time then stored identity, newest first. Follow nextCursor with the same conversation and limit until hasMore=false. Each case contains its latest five events in chronological order, eventsHasMore and eventsNextCursor for list_conversation_handoff_events. Resolution details are fetched independently of the preview. Captured/missing fields, property/working-hours context and resolution remain available. Cases/events can change during reads; deduplicate identities. Check current conversation handoffStatus/activeHandoffCaseId for current ownership, which may not be on a historical page. Reads never resolve a case or send a notification.
