Do I need to retest? Accessibility change decisions
A changed page does not tell you which earlier checks still apply. These worked examples connect a specific change to the evidence that needs another look. They are learning aids, not accessibility certifications.
Start with the change you made.

A changed target is affected. Missing baseline continuity, missing styles or a changed shared stylesheet can make the impact uncertain. Neither state justifies silently reusing an earlier approval. The worksheet includes not tested and cannot determine, so missing evidence stays visible.
