Field notes

• Timestamps are ISO-8601 UTC instants. There is no timezone field.
• mode — "ambient" (device-initiated on speech) or "manual" (user-initiated recording).
• title / summary — model-generated after processing. title is always present (falls back to a generic label); summary may be null.
• participants — one entry per detected speaker. matched: true means the voice resolved to a workspace member; name / email are theirs. Unmatched speakers (guests, unenrolled members) have null name/email — label is the pipeline’s local label for them. speech_ms is total speaking time.
• segments — the source of truth: time-ordered utterances with speaker attribution (speaker is null for unattributed audio).
• transcript_text — convenience plain-text rendering of the same segments (one speaker-labeled line per consecutive same-speaker run), so an ingestion agent can consume text without assembling segments.
• device — the room, in practice: devices are named after where they live.
• calendar_event — reserved, always null today. When Parable’s Google Calendar integration lands it will carry the matched event; additive, no schema break.
• emitted_at — when this document was rendered.
