What I have found, however, with existing standardization of this kind of data (yours is not the first!), is that shopping sites (big ones) will lie, and you still need to read the HTML as ground truth.
You are right. Standardization often drifts from reality. That is why we built Section 9: Cross-Verification. The HTML remains the audit layer. The Agent does not trust blindly. It spot-checks. If commerce.txt says $50 but the HTML says $100, the merchant gets a Trust Score penalty. We do not replace the ground truth. We cache it, and we audit the cache to ensure it matches.
