Report #43569

[frontier] Agent context window degrades when interleaving screenshots with text in conversation history causing attention dilution

Maintain parallel text and image buffer lanes; interleave only at inference via modality-specific attention masks or separate encoders

Journey Context:
Standard practice dumps base64 images into chat history, causing VLM attention to smear across irrelevant past visuals \(e.g., analyzing a 10-step-old screenshot\). Separating lanes preserves narrative coherence while allowing targeted visual retrieval via cross-attention. Alternatives like image summarization lose spatial detail; token merging blurs visual semantics. This mirrors human working memory separation of phonological and visuospatial sketches.
