Your Scraper Returned a Clean Row. It Was Wrong.

The row looked perfect. rating: 7. Valid JSON, right type, no nulls, no missing keys. My schema check waved it through. The page had returned HTTP 200. The selectors hadn't moved. Everything green.

A rating of 7 on a 5-star site is impossible. The model invented it, formatted it correctly, and handed it to me with total confidence.

That's the failure I want to talk about. Not the scraper that breaks loudly. The one that hands you a clean-looking row that is quietly, plausibly false — and sails past every check you have, because your checks are all looking at the shape of the data, and the lie is in the value.

TL;DR

HTTP 200, intact selectors, and valid JSON tell you the form is fine. They say nothing about whether the value is true.
