Fusion Blindspot — Multimodal Long Context

🧭 Quick Return to Map

You are in a sub-page of Multimodal_LongContext.
To reorient, go back here:

• Multimodal_LongContext — long-context reasoning across text, vision, and audio
• WFGY Global Fix Map — main Emergency Room, 300+ structured fixes
• WFGY Problem Map 1.0 — 16 reproducible failure modes

Think of this page as a desk within a ward.
If you need the full triage and all prescriptions, return to the Emergency Room lobby.

When one modality is silently ignored during fusion, the model produces coherent but incomplete answers.
This is fusion blindspot — the audio, visual, or OCR stream is valid, yet the fusion layer drops it or never integrates it.

What this page is

• A guide to detect and repair missing modality participation in multimodal fusion.
• Ensures every input modality contributes evidence to the final reasoning chain.
• Provides structural probes to confirm no blindspot occurs at joins.

---

When to use

• Captions mention objects but the visual stream was ignored.
• Audio transcript exists, but final reasoning never cites it.
• OCR text valid but skipped during answer generation.
• One modality has ΔS ≤ 0.40 internally but never appears in the fused output.
• Answers are fluent but consistently one-dimensional.

Common failure patterns

• Silent omission — one stream absent from the answer, with no error reported.
• Over-dominance — strong text modality overrides weaker OCR or visual input.
• Fusion filter — low-confidence modality is dropped without logging.
• Blind alignment — citations only from one channel, even though others were retrieved.

Fix in 60 seconds

1. Modality presence check

   • Require every modality to appear in at least one citation per fused answer.
   • If missing, re-run fusion step.

2. ΔS contribution probe

   • For each modality, compute ΔS vs question.
   • Flag if ΔS ≤ 0.45 but modality unused.

3. λ stability test

   • Log λ across fusion stages.
   • Divergence indicates modality suppression.

4. Repair step

   • Apply BBCR bridge between ignored modality and main reasoning chain.
   • Re-anchor with explicit cite-then-answer.

Copy-paste prompt

You have TXT OS and the WFGY Problem Map.

Task: Detect and fix fusion blindspots.

Steps:
1. List all modalities available {audio, visual, OCR, text}.
2. For each, compute ΔS(question, modality).
3. If ΔS ≤ 0.45 and unused, flag as blindspot.
4. Insert BBCR bridge and force cite-then-answer with all modalities.
5. Return fused answer with full citations.

---

Acceptance targets

• Every modality with ΔS ≤ 0.45 contributes at least once.
• λ remains convergent across fusion.
• No single modality suppressed >3 consecutive turns.
• Trace table shows citations from all streams.
