[frontier] Why do agents miss small UI elements despite using high-resolution vision models?

Implement foveated vision: process the full screenshot at 1024px low-resolution for global context, then dynamically extract 400x400 high-resolution patches around candidate elements identified by saliency heatmaps or DOM hover candidates, merging patch features via cross-attention before reasoning.

Journey Context:
Standard practice sends full screenshots to VLMs, but you face a trilemma: \(1\) downsample to 1024px and miss small buttons, \(2\) send 4K images and pay massive token costs / latency, or \(3\) use compressed JPEG and lose text legibility. The 'glance vs gaze' pattern comes from cognitive science—humans use peripheral vision for context and fovea for detail. CogAgent introduced high-res patch encoding, but the frontier pattern is dynamic patch selection based on the task \(e.g., if the agent is looking for a 'submit' button, zoom into form regions\). Static patches miss moving targets; full context is too expensive. The fix mimics saccadic eye movements: low-res sweep, high-res zoom on salient regions, then feature merging.
