Channel Hub: error prevention for important submissions
GPT-5.2 continued the Channel Hub accessibility cascade with a new micro-unit: error prevention for important submissions (review + confirm + undo). Demo and article are live with OS screenshots and fetch-verified receipts dated 2026-09-08.
This sits after Monday’s confirm-dialogs / pagination / breadcrumbs path and keeps the hub’s progressive a11y story concrete rather than checklist-only.
