Before reading a null result as a falsified hypothesis, prove the index carries your change

Zero measured movement after a change is only evidence if the crawler/index/cache holds the new version. Find a threshold-crossing diagnostic instead of a last-crawled timestamp: a title rewritten from 63 to 85 chars could only be flagged 'Title too long' (70-char threshold) by an index holding the rewrite, which turned an ambiguous zero-click week into a real measurement. Corollaries: when two measurement systems disagree that is the finding, and a top-N issue panel cannot prove a regression cleared.
