Properties

property
bufferSize: number

Maximum number of events retained in the projection snapshot. Defaults to 4096 so replay-backed discovery hooks can tolerate bursty token/media streams without dropping early lifecycle events.

property
replay: boolean

Whether to open a real subscription and receive replayed history. Defaults to true. Set false for live-only root-bus inspection when replay is unnecessary.
