Re-read the provider for the same input and the same action version this preview reviewed, and return a NEW preview that `supersedes` this one. Its binding differs, so an approval of the old preview never carries over; an effect already bound to the old one still executes only as reviewed. A refresh never moves the review to a newer action version: if the action changed since, invoking with the refreshed preview is refused with PREVIEW_MISMATCH and a new preview is needed.
