**Confirm both versions finished processing.** Open each version and check its processing status is complete, not pending or failed. Expected: both versions show complete, with clause extraction finished.

**Re-run the comparison instead of reopening a cached one.** Start a fresh compare from the agreements list, picking the older version as the base and the newer version as the comparison. Expected: the compare loads with a new timestamp.

**Check the highlight settings.** In the compare view, turn on highlighting for insertions, deletions, and moved text, and set the view to show all changes, not only substantive changes. Expected: formatting-only filters no longer hide wording changes.

**Open the specific clause that changed.** Jump to the clause in both panes and confirm the wording actually differs in the extracted text, not only in the scanned image. Expected: the extracted text shows the difference; if it does not, the problem is extraction, not highlighting.

**Re-process the newer version if extracted text matches the old one.** Remove and re-add that version, wait for processing to complete, then compare again. Success check: changed wording is highlighted in both panes and the change summary lists the clause.
