What probably matters to youSection of the release
What
The error result message and the first non-ping stream event of a turn can both carry user_message_uuid, the client uuid of the prompt that started the turn, so a stream or a failure can be matched to its send immediately.
Details
The schema field is optional, so older producers simply omit it.
Absent on meta and scheduled turns and on any turn submitted without a client uuid.
Evidence
Client uuid of the user message that triggered this turn (submitMessage options.uuid), stamped on the turn's FIRST non-ping stream event only
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
