Options for injectChannelEffect. Extends the projection
options (bufferSize, replay) with the per-event callback, an
optional error sink, a target scope, and an enabled gate.
interface InjectChannelEffectOptionsMaximum 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.
Gate the subscription. When false, no subscription is opened and
no events are delivered. Defaults to true. Accepts a Signal.
Invoked when onEvent throws. When omitted, a throwing
onEvent is swallowed so one bad delivery cannot wedge the shared
store's notification loop or other consumers.
Invoked once for every event observed while attached.
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.
Scope events to a subagent / subgraph / explicit namespace.
Defaults to the root namespace. Accepts a Signal so a computed
scope re-binds the subscription automatically.
