Published measurements—not a self-awarded score
These metrics are calculated directly from the current build's source register, topic relationships, review status and public ledgers. They make coverage and transparency checkable, but do not prove every conclusion correct, peer reviewed, certified or externally recognized.

How to read zero: Zero means no verified public record is present. It does not mean the site cannot contain error or that no private feedback exists. An automated accessibility perfect score is not a formal conformance statement.
