Each defect is one place in the product, however many screens it appeared on.

What this report is

A clean result is not a statement of conformance. It means no automated check found a violation. Conformance with the European Accessibility Act also requires testing by a person — reading the screens with a screen reader, working them with a keyboard, judging whether the wording makes sense — and someone willing to sign for it.

Automated checking finds a minority of real accessibility problems. It is good at what it covers and silent about the rest, and the clause table below says plainly which is which.

Accessibility (EN 301 549)

What the European Accessibility Act asks of an app, through the standard it points at.
