Fold new dev-log entries back into docs/dev-file volumes (the current-truth architecture docs), then bump each volume's 最后核对 stamp. Use when the user asks to distill/reconcile dev-file, run the weekly docs pass, or close out a workstream. Processes only the delta since each volume's stamp — cheap when run regularly.

Build or review accessible React UI. Use when implementing UI components, reviewing UI code, checking accessibility, choosing Base UI React primitives, or validating forms, overlays, keyboard behavior, focus management, accessible names, and Testing Library queries.
