AlertDialog

Confirms something you cannot undo. Narrower than Dialog at 416px, with no dismiss X and no click-out.

Every destructive action opens one — button, menu item, row action or bulk action alike.
Name the consequence in the title, not “Are you sure?”.
The trigger is destructive-outline; the filled destructive button exists only as the confirm inside the dialog.
A reversible action raises an undo toast instead. Only irreversible ones earn a confirm dialog.
