# ReplayFrom

> Where a v2 replays history from.

Where a v2 `session/resume` replays history from. `start` replays the
whole transcript (what v1 `session/load` does); the Cognition tail cursor
replays only the newest `limit` events plus a sparse history skeleton.

```typescript
type ReplayFrom = { type: "start" } | { limit: number; type: typeof void }
```
