Public Composite.ActiveIdState behavioral model.

Initial Composite values. activeId defaults to null, orientation to horizontal, loop to true, RTL and virtual focus to false.

Complete renderer-independent state for Composite.

Effect Schema used by makeState to encode, decode, and hydrate Composite state.

Creates hydrated Composite state. activeId defaults to null, orientation to horizontal, loop to true, RTL and virtual focus to false.

Focuses the registered active element unless state uses virtual focus or has no active id.

Calls an existing platform focus method inside Effect.sync and otherwise does nothing.

Moves active state, then focuses and scrolls the mounted active item when virtual focus is disabled.

Calls scrollIntoView with nearest block/inline alignment for the mounted active item.

Logical movement operations independent of physical key names.

State, collection, and disabled-item policy consumed by Composite movement helpers.

Supported composite movement axes.

Computes the next active id and updates state; collection and state failures/services are preserved in the returned Effect.

Returns the id reached by first/last/next/previous with optional disabled inclusion and loop policy.

Returns the full item selected by moveActiveId, or undefined when no item is reachable.

Sorts a copy by mounted DOM order and then removes disabled items.

Derives activeId only under virtual focus, otherwise undefined.

Derives 0 when the root owns focus and -1 once a roving-focus item is active.

Derives 0 only for the active item under roving focus; virtual-focus items always receive -1.

Public Composite.KeyboardEventLike behavioral model.

Maps Home/End and orientation-aware Arrow keys to movement, reversing horizontal arrows for RTL.

Prevents the native key default only when keyMove recognizes the key, then updates active state.

Public Composite.TypeaheadBuffer behavioral model.

Returns the first enabled item id in DOM order whose textValue starts with the query.

Returns only the id selected by typeahead, or null when no item matches.

Returns an unmodified one-character key exactly as provided; modified and multi-character keys return null.

Appends within the timeout window and starts a new query after the buffer expires.
