readonly events: AgentHarnessEventPort

​

On the Agent Runtime

// runtime-adapter.ts
const events = Object.freeze({
  emit: (type, payload) => host.events.emit(type, payload),
  read: (afterSeq, limit) => host.events.read(afterSeq, limit),
  count: () => host.events.count(),
});

• emit() calls this.events.emit(), which assigns the event’s seq and writes its row in one commit.
• read() calls this.events.read(). afterSeq is exclusive, and only retained events are returned.
• count() calls this.events.count(), the number of events ever emitted. It includes events already pruned.
• StoredEvent is the runtime SDK’s own type.
