Investigation

Something went wrong. Start with what you observed.

You do not need to know the cause or WCAG criterion. This guided investigation helps you decide what to check next without pretending the first explanation is necessarily correct.

Investigations are added gradually as their reasoning paths are reviewed against the Barrier Library and evidence model.
