  "description": "Stable server-generated identifier used across every wire flow (REST request body, webhook payload, WebSocket envelope, COM GetResults). UUID-format `*Id` properties — `sessionId`, `caseId`, `requestId`, `deliveryId` — reference this type. Partner-controlled identifiers (`instanceId`, `targetUserId`) reference `_common/OpaqueIdentifier` instead. Drift to a different type (integer, uuid-without-format, custom string) fails the uniformity test (#640).",
