Market Readiness Index — Edition 2

Known engine defect, published rather than hidden

Store Guard v0.3 scores product_schema and agent_ready against whichever page its homepage product-link discovery lands on, and does not verify that the page is a product. On 29 storefronts the fetch resolved to a non-product page — most often the homepage after a redirect, or a Salla /p/<slug> static page such as a privacy policy or an "about us" page, whose URL shape mimics a product URL. On a further 29 no product page was reached at all and the engine recorded the axis as inconclusive. Reported as an engine defect by campaign-D's falsifier on 2026-08-11 and confirmed here against every audit in the set.

Because product_schema carries 15 of the 100 rubric points, an unverified row that was scored zero on that axis can be understated by roughly 17 points on the renormalised denominator — enough to move a grade. That is why unverified rows publish no total and no grade here rather than a corrected one: the engine's receipts attest the scores it issued, and inventing replacements would break that chain.
