CHK022 - Are interaction requirements defined for mobile touch gestures (swipe to close)? [Coverage, Gap]
CHK023 - Are requirements defined for very long messages (text wrapping, truncation)? [Coverage, Edge Case]
CHK024 - Are requirements defined for very long session lists (50+ sessions)? [Coverage, Edge Case]
CHK025 - Are requirements defined for zero-state (first time user, no sessions)? [Coverage, Gap]

Edge Case Coverage

CHK026 - Are visual requirements defined for network error states on message send? [Edge Case, Spec §FR-014]
CHK027 - Are requirements defined for attachment upload progress indication? [Edge Case, Gap]
CHK028 - Are requirements defined for attachment upload failure states? [Edge Case, Gap]
CHK029 - Are requirements defined for when drawer cannot expand due to viewport constraints? [Edge Case, Gap]
CHK030 - Are requirements defined for rapid consecutive message sends? [Edge Case, Spec §Edge Cases]

Non-Functional Requirements (UX Focus)

Accessibility

CHK031 - Are keyboard navigation requirements defined for drawer open/close? [Accessibility, Gap]
CHK032 - Are ARIA attributes requirements specified for drawer component? [Accessibility, Gap]
CHK033 - Are focus management requirements defined (focus trap when drawer open)? [Accessibility, Gap]
CHK034 - Are screen reader announcement requirements defined for AI response streaming? [Accessibility, Gap]
CHK035 - Are color contrast requirements specified for message differentiation? [Accessibility, Gap]

Responsive Design

CHK036 - Is the mobile full-screen overlay behavior completely specified? [Completeness, Spec §FR-017]
CHK037 - Are breakpoint thresholds for mobile vs desktop defined? [Clarity, Gap]

Animation & Performance

CHK039 - Are animation requirements defined to respect prefers-reduced-motion? [Accessibility, Gap]
CHK040 - Are performance requirements for message list rendering with 100+ messages defined? [Performance, Spec §SC-003]

Dependencies & Assumptions

CHK041 - Is the assumption that TDesign components will be used validated against existing patterns? [Assumption, Constitution §IV]
CHK042 - Are BEM naming conventions for new CSS classes documented? [Dependency, Constitution §IV]
CHK043 - Is the dependency on existing icon library documented? [Dependency, Gap]

Ambiguities & Conflicts
