Attaches a transcript to an existing calendar meeting. Never creates meetings, and never stores audio or video.

Prefer meeting_id from list_meetings or get_meeting. Otherwise send calendar_event_id (Google Calendar events.id) or ical_uid, plus started_at when the id belongs to a recurring meeting. Unmatched rows return unmatched_meeting: skip them, do not invent a meeting.

The transcript is only stored when Monaco has not covered the meeting itself. Check transcript_source on get_meeting before posting. Rejections carry a machine-readable error.code and write nothing:

• monaco_recorder_configured (409): Monaco's recorder handles this call.
• transcript_exists (409): the meeting already has a transcript, or this external_id is stored with different content. A meeting holds at most one imported transcript.
• do_not_ingest (409): the meeting or its series is marked do-not-ingest.
• ambiguous_meeting (422): several occurrences match; resend with started_at.
• meeting_not_ended (422): the meeting has not finished yet; retry after it ends.
• unmatched_meeting (422): no meeting matched the identifiers sent.
• privacy_blocked (403): org privacy settings block this meeting's content.
• meeting_deleted (410): the meeting was deleted.

Retries with the same external_id and the same transcript return created: false.
