What [`history.group`](History.group.md) takes.

## Members

| Member | Kind | Summary |
| --- | --- | --- |
| <a id="label"></a>[`label?`](HistoryGroupOptions.label.md) | property | The undo label of the group's one step. |
| <a id="actor"></a>[`actor?`](HistoryGroupOptions.actor.md) | property | Writes passing this group as `expectGroup` default to this actor (one that passes `actor` keeps its own; a write that passes neither is 'app', a drag's runtime commit 'shopper'). |
| <a id="timeoutms"></a>[`timeoutMs?`](HistoryGroupOptions.timeoutMs.md) | property | Commits itself after this long. |
| <a id="signal"></a>[`signal?`](HistoryGroupOptions.signal.md) | property | Aborting commits the group. |

## Declaration

```ts
export interface HistoryGroupOptions {
  label?: string;
  actor?: Actor;
  timeoutMs?: number;
  signal?: AbortSignal;
}
```

## Generic-API test (spec 3.1)

| Rule | Result |
| --- | --- |
| 1. Neutral name | pass: `HistoryGroupOptions` names no product |
| 2. A precedent | not recorded: no ledger row (coverage.json) names this member or its owner |
| 3. Two apps, or labs | not recorded: no ledger row names this member or its owner |
| 4. The cheaper fix first | not recorded per member (Appendix B decides it per need) |
