Report #47006

[frontier] Token-based truncation destroys visual coherence in long sessions

Maintain a structured scene graph of UI elements \(type, location, relationships\) that can be re-rendered to text or image as needed, rather than storing raw screenshots

Journey Context:
As agents run for hours, storing all screenshots is impossible. Summarizing them loses layout detail. The Google ScreenAI approach parses screens into structured representations: 'Window X contains Button Y at \(100,200\), child of Container Z.' This forms a graph. For context management, the agent keeps this graph, not pixels. When the model needs to 'see' the screen, the graph can be rendered as text \(structured HTML-like\) or even re-synthesized to a clean wireframe. This compresses context 10x while preserving spatial relationships, enabling truly long-horizon automation.
