Manual test checklist

Plan extra time for VoiceOver, Switch Control, device rotation, and real-world flows (media, authentication, motion) even when automation is green. Use Understanding WCAG 2.2 and Apple’s Human Interface Guidelines alongside this list.

Area	Manual verification focus
1.2.x Time-based media	In-app video/audio (captions, descriptions, live captions): validate with real content.
1.3.2–1.3.5 structure & input purpose	Meaningful sequence, sensory-only instructions, orientation lock justification, `UITextContentType` / WebView `lang`: design and assistive-tech pass.
2.x keyboard / focus / timing (full)	Complete tasks with VoiceOver and hardware keyboard; session timeouts and motion: exercise beyond rule snapshots.
3.x language, errors, help	Error suggestion quality, legal safeguards, help consistency: product and compliance review.
AAA criteria	Optional stretch goals: schedule only when AAA is explicitly in scope.
