Interface ReactionSink

A scope-keyed delta consumer. The normal player path delivers per-viewer via MessageApi.sendEnvelope; an explicit sink is the seam for the read-only service:broadcast overlay principal (which has no Interactive) and for tests.

interface ReactionSink {
    id: string;
    viewer?: Stuff & Sensor | null;
    emitDelta(env: Omit<ReactionDeltaEnvelope, "frameId">): void;
    seesScope(scope: string): boolean;
}
