Limitations

Source intelligence does not replace manual accessibility review. Browser audits reflect the rendered DOM at audit time; they do not fully simulate assistive technologies.

Source mapping

Condition	Typical outcome
Production minified assets	Weak or unmapped
Client-only components	Candidate may point to a wrapper
Third-party widgets	May map only to the integration boundary
Multiple matching components	ambiguous, with ranked candidates

Never treat likely source as proof of compliance without checking the file.

Recommendations

They do not apply patches, may need design or content decisions, and ask for manual verification on subjective rules (contrast, visual design).

Mappers exist for html, react, next, vue, nuxt, and angular. Keyboard, large-text, and reduced-motion findings may map or recommend less completely than axe-sourced rules.

With sourceAnalysis.enabled: false, findings still include severity, evidence, and reports — without mapping or recipes.
