Evidence labels
Official supports product identity, specifications, compatibility and policy. Independent adds hands-on context. Study describes a specific device, algorithm, sample and reference method. Regulatory is required for clearance claims.
Review cycle
Each record stores a check date and exact supported claim. A source does not support facts it never states. Unknown price, size, market or feature access remains unknown.
Editorial conclusions
Verdicts combine hard constraints and documented trade-offs. There is no hidden universal score and no hands-on claim unless a method is published.
Commercial separation
Direct official destinations come first. Affiliate approval can change a link, never the underlying specification or shortlist.
