Verify prior feedback in later proof rounds

AI Proofing now includes a "Verify prior feedback" review mode for later proof rounds. Instead of starting a fresh editorial review, Hive checks each eligible earlier human comment and records whether it was completed, partially completed, not completed, or could not be verified, with evidence and confidence. New AI suggestions are suppressed by default in this mode.

Choose Verify prior feedback when reviewing a later proof round, then use the results checklist and links to inspect the prior target and current-version evidence.

This helps proofing teams, reviewers, and creative teams confirm that requested changes were addressed without manually rechecking every earlier comment.
