Clusters krijgen een vingerafdruk via genormaliseerd selectorpad + regel-id + snippetvorm. Rangscore = (ernstgewicht × getroffen pagina's) / verschillende componenten voor de regel. Dit vervangt de template-drempelheuristiek, maar behoudt die als validatiesignaal.

Foutrapporten

5 probleemtype(n) worden standaard getoond van in totaal 12. Geprioriteerd op ernst, belangrijke pagina's, WCAG-niveau en prevalentie; gebruik de schakelaar om alles te tonen.

Algehele verdeling van ernst: 2 ernstig, 10 matig. Per WCAG-categorie: 4 WCAG 2.0 A, 1 WCAG 2.1 A, 2 WCAG 2.x AAA, 3 Beste praktijk, 2 Onbepaald. Geordend op ernst, impact op belangrijke pagina's, WCAG-niveau en prevalentie. Volgens de best practices voor het rapporteren van toegankelijkheidsbugs. Downloaden: Markdown · JSON (volledig archief) · JSON (AI-diagnose) · CSV (alle bevindingen) · CSV met prioriteitspagina's · JSON met prioriteitspagina's.

Automated testing does not establish full WCAG conformance. Findings in the verification lane require manual testing before they are treated as confirmed failures.

De standaardweergave toont 5 geprioriteerd(e) probleemtype(n); 7 meer zijn beschikbaar als u overschakelt naar "Alles tonen".

1 bevinding(en) gemarkeerd als "mogelijk duplicaat" — Alfa en axe-core markeerden beide hetzelfde WCAG-succescriterium op overlappende pagina's. Als ze hetzelfde element betreffen, is het axe-core-rapport doorslaggevend. Filter de CSV op possible_duplicate_of om deze te zien. Dat twee engines dezelfde barrière markeren, verkleint de kans op een vals positief.

Findings needing review

These findings need manual verification before they can be treated as confirmed failures. Obligation remains visible for each finding.
