Report #78131

[frontier] Agents fail on modern web apps because DOM structure diverges from visual rendering \(CSS transforms, canvas, WebGL\)

Implement hybrid perception: use DOM for semantic structure \(labels, roles\) but verify interactability via screenshot-based pixel classification, rejecting elements that are visually occluded or transformed out of clickable space

Journey Context:
Pure DOM-based agents \(Playwright-style\) fail when CSS transforms rotate elements, when elements are visually hidden by overlays, or when using Canvas/WebGL \(Figma, Google Maps\). Pure vision agents miss semantic context \(ARIA labels, input types\). The common error is choosing one paradigm. Leading implementations now use DOM to generate candidate actions \('clickable elements'\), then use vision to validate \('is this actually visible and unobstructed?'\). This catches modal dialogs that DOM says exist but are behind overlays, or buttons rotated via CSS. Trade-off: latency from dual parsing. Essential for modern SPAs and design tools.
