Struct EventEnvelope 

pub struct EventEnvelope {
    pub event_id: EventId,
    pub stamp: FrameStamp,
    pub kind: EventKind,
    pub track_id: Option<TrackId>,
    pub subject_id: Option<SubjectId>,
    pub zone_id: Option<ZoneId>,
    pub evidence: Option<EvidenceRef>,
    pub payload: EventPayload,
}

Versioned, queryable event record for a VisionIndex.

This is the shared contract between tracking, analytics, storage, and host products. It does not embed pixels or edit instructions.

Fields

event_id: EventId

Stable event id within an index document.

stamp: FrameStamp

Temporal and source stamp for the event.

kind: EventKind

Coarse kind for filtering.

track_id: Option<TrackId>

Optional track association.

subject_id: Option<SubjectId>

Optional long-lived subject association.

zone_id: Option<ZoneId>

Optional zone association (also often present in payload).

evidence: Option<EvidenceRef>

Optional evidence handle for reels / audit.

payload: EventPayload

Kind-specific payload.
