When captions are delivered, how do the primary sources keep essential visual information (audio description, text descriptions) and structural navigation available?
Captions cover audio; essential visuals are covered separately. WCAG 2.2 requires audio description or a media alternative at Level A and audio description at AA; its definition says description covers actions, characters, scene changes and on-screen text and is not needed if the audio already carries the visual information. MAUR (Note 3 Dec 2015) adds format requirements: time-synchronised description tracks, text video descriptions reachable by screen reader/Braille, and structure-based navigation of media that current players lack.

Curator qualifications: Essential visuals go to audio description, not captions; WCAG AD definition; MAUR description track formats.
Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
