Report #74960

[frontier] Agent reasoning degrades when interleaving vision analysis and text reasoning due to base64 token pollution in context window

Implement strict modal segmentation—flush vision tokens or rotate to a fresh context window before text-heavy reasoning phases, keeping only semantic summaries of visual analysis

Journey Context:
Base64 image tokens consume thousands of tokens per screenshot. When agents alternate between analyzing screenshots and text reasoning, residual image tokens dilute the attention mechanism, causing the model to fixate on visual details when it should be reasoning abstractly. Common mistake is keeping all historical screenshots in context. The fix treats vision and text reasoning as separate 'modes' with context barriers between them.
