RootHost

• Subscribes to Core Root and enriches notifications with seq: bigint, ts: string, version: 1, and optional traceId/actor.
• Fans out to all registered adapters, preserving order per adapter.
• Executes fanout asynchronously and swallows adapter errors to isolate failures.
• Provides emit(), compact(), and shutdown(); shutdown() waits for adapters' drain().

Usage sketch:

import { RootHost } from '@minamorl/root-host'; import { makeRoot } from '../src/lib/root'; import { SseAdapter } from '@minamorl/root-adapters/sse';

const root = makeRoot(); const sse = new SseAdapter(); const host = new RootHost(root, [sse]); host.emit({ type: 'Create', id: 'x', value: 1 }, { traceId: 't1' });
