**Category:** Base Components/Collections/NestedTable

## API

### Overview

Extends the standard optimistic actions API with nested-table-specific operations. Provides `updateMany`, `updateOne`, `deleteMany`, and `deleteOne` methods that accept a `propagate` parameter to cascade changes to child nodes. Access via `nodeState.optimisticActions`.
