+## Bulk actions
+
+With `rowSelection`, `renderBulkActions` receives effective `selectedRows`,
+`selectedCount`, and `clearSelection`. Use these IDs for operations, not the
+unfiltered controlled selection. `clearSelection` requests an empty selection,
+including retained IDs; controlled consumers apply `onSelectionChange`.
+
+Actions occupy the table header beside select-all, replacing the visible column
+labels while rows are selected. Column names remain available to assistive
+technology, but custom header controls are hidden and sorting controls are removed
+until selection is cleared. The
+named action group uses native Tab/Shift+Tab navigation. Count changes are
+announced, including zero. Use `bulkActionsProps`
+to localize the group name and count label. The header checkbox toggles selection;
+there is no separate clear button. Use small action buttons to fit the header.
+
+Showing actions preserves checkbox focus. When clearing selection or updating
+rows removes the focused action, `DataTable` restores focus to select-all, or to
+the table when no selectable rows remain. `bulkActionsReturnFocusRef` overrides
+that destination. This also applies when an action removes itself without updating
+the table. Focus is not restored after the user leaves the actions or
+moves into a consumer-owned dialog. When composing `Table.BulkActions` directly,
+keep it mounted at zero and provide `onFocusReturn` for recovery.
+
+Consumers own pending states, result announcements, and focus when closing
+dialogs or replacing the table. For asynchronous operations, capture the effective
+IDs at activation and reconcile only those IDs on success; preserve selection on
+failure and do not clear selections added while waiting.
+Collapsing a group does not exclude its selected rows from bulk actions.
+See `WithBulkActions` in [DataTable features](./DataTable.features.stories.tsx).
