[frontier] Cross-Modal Attention Bias: Vision encoder biases leak into text reasoning \(e.g., CLIP associating 'danger' with red colors regardless of semantic context\)

Implement modality isolation phases: first extract structured text description from image via OCR/captioning, then disable vision encoder and reason on text-only representation for decision logic. Re-enable vision only for final verification step. Never allow vision features to directly influence high-level planning without text intermediation.

Journey Context:
Multimodal models exhibit 'visual priming'—showing a dark/ominous image biases the model to generate more negative/risk-averse text, even if the task is neutral. In agents, this causes 'color bias' \(red buttons seen as dangerous even when they're just brand colors\). The fix is 'disentangled reasoning'—process visual information to extract neutral text facts first \(e.g., 'button color: \#FF0000, text: Submit'\), then reason on those facts. This prevents low-level visual features \(color, texture\) from leaking into semantic reasoning.
