Report #44677

[frontier] Pure screenshot agents miss hidden DOM states \(shadow DOM, accessibility properties\); pure DOM agents miss visual layout and styling, causing failures on canvas-based or visually dynamic UIs

Maintain a synchronized dual representation: a 'ghost accessibility tree' overlaid on pixel space that queries DOM properties \(clickable, visibility, ARIA labels\) while reasoning over visual layout, with explicit conflict resolution logic that prioritizes visual evidence when CSS indicates visibility:hidden or DOM indicates disabled but visual suggests otherwise

Journey Context:
DOM-only agents fail on React/Vue shadow DOM and canvas apps \(Figma, Google Maps\). Screenshot-only agents can't read ARIA labels or know if an element is technically 'disabled' despite looking clickable. The ghost state requires bidirectional sync: updating DOM queries when pixels change, and flagging visual regions when DOM updates. This is distinct from naive 'combined' approaches because it explicitly handles divergence \(e.g., A/B testing where DOM and pixels are momentarily inconsistent\).
