Changelog 2026-03-06 (Command Palette ARIA Listbox Pass)

Published Mar 6, 2026

Changed

Upgraded command palette input semantics to a combobox pattern (role="combobox", aria-controls, aria-expanded, aria-activedescendant).
Upgraded results container semantics to a listbox with option roles and explicit aria-selected state.
Added active descendant synchronization as keyboard focus moves through results.
Added loading/empty-state handling for active descendant reset and status output when no matches are found.

Why

This focused batch advances the ongoing accessibility sweep for interactive keyboard-first UI.
The update improves screen-reader orientation and command palette navigation clarity without changing visual behavior.
