TypeScript Event Names

Event names in TypeScript use camelCase (e.g., taskCompleted, not TaskCompleted):

typescript

program.addEventListener('taskCompleted', callback);
program.addEventListener('disputeResolved', callback);
program.addEventListener('reputationStaked', callback);

Subscribing to Events

typescript

import { EventMonitor, createReadOnlyProgram } from '@agenc/runtime';

const program = createReadOnlyProgram(connection);
const monitor = new EventMonitor({ program, logger });

monitor.subscribeToTaskEvents({
  onTaskCreated: (event, slot, sig) => { /* ... */ },
  onTaskCompleted: (event) => { /* ... */ },
  onTaskCancelled: (event) => { /* ... */ },

Event Replay

The runtime includes an event replay system for incident investigation:

typescript

import { ReplayStore, BackfillService } from '@agenc/runtime';

// File-based replay store
const store = new ReplayStore({ type: 'file', path: './replay-data' });

// Backfill historical events
const backfill = new BackfillService({ store, connection });
await backfill.run({ fromSlot, toSlot });

// Query timeline
const events = await store.query({ timeRange, eventTypes, agentId });
