Report #68741

[frontier] Agents face a forced choice between high-latency screenshot analysis \(accurate visual understanding but 2-5s per step\) vs. low-latency DOM parsing \(fast but misses visual state like colors, charts, canvas elements\)

Implement 'Hybrid State Representation': use accessibility trees/DOM for structure and navigation \(fast\), but trigger screenshot analysis only for 'visual verification' steps \(reading charts, checking colors, validating rendered output\)

Journey Context:
Pure screenshot agents \(like early Computer Use demos\) are slow because encoding a 1080p screenshot through a VLM takes 2-4 seconds per step. Pure DOM agents \(traditional web automation\) are fast but blind to canvas, images, and CSS styling. The emerging pattern in 2025-2026 is 'bifurcated perception': the agent maintains two representations of the environment. For actions like 'click the submit button', it uses the accessibility tree \(fast, structural\). For actions like 'is the chart trending up?', it invokes the vision model on the specific bounding box \(slow but accurate\). This requires an 'attention router' that decides which perception module to use based on the action type.
