Source hierarchy
Current first-party product and terms pages support operator facts. Official regulator sources support licensing statements. Dated screenshots support only what appears in the capture.
Editorial judgment
A score or recommendation must use a documented basis. Unknown values cannot quietly become zero, false or a negative rating.
Corrections
Material corrections update the affected page and evidence date. Conflicting sources remain labelled until resolved.
Commercial separation
Affiliate links are disclosed and marked as sponsored. Commercial availability does not prove a better product.
