  "rationale": "Opt-in evidence naming a different company than the brand is the single clearest sign that the wrong entity was registered — the consent belongs to whoever is named on the page, and that is not the brand being registered. It is also what an ISV registration looks like from the outside, which is why reviewers treat it as decisive rather than as a filing error.",

What it cannot see is the domain rendered INSIDE a screenshot — an artifact hosted on the brand's CDN can still show another company's checkout — so a PASS here is a necessary condition rather than a sufficient one, and the vision rules judge the picture itself.",
