Interface EventEnvelope<T, P>

Event contracts. State changes are immutable, attributable, versioned events. Current state is derived by folding events, never by mutating rows in place.

    actor: string;
    at: number;
    id: string;
    payload: P;
    schema: number;
    seq?: number;
    tenantId: string;
    type: T;
}
