[frontier] Full screenshot history improves state understanding but degrades action grounding

Do not prepend full historical screenshots to every turn. Keep structured state diffs and text action logs; retain only the most recent full screenshot and task-relevant region crops. For long tasks, summarize older visual history into structured notes or before/after crops.

Journey Context:
A 2026 failure-mode study on OSWorld found that full-image visual memory reduced visual-state misunderstanding \(73.1% to 69.6%\) but consistently worsened action-level failures, increasing hidden-operation blindness by 11.7 percentage points. Extra pixels crowd the model with irrelevant cues and distract from invisible state changes like scrolls, loading states, or backend updates. This explains why many production vision agents loop: they see too much history and too little of what changed. Region-aware memory is the fix.
