When multimodal sessions extend across long contexts, one or more modalities may **drop out entirely** or become invisible to the reasoning pipeline.  
This creates “blind layers” where text, image, or audio cues vanish mid-sequence, leading to broken reasoning or silent hallucination.

---

## Symptoms of Signal Drop
- Model responds as if a modality was never provided.  
- Visual reference ignored after ~20–30 turns.  
- Audio transcript included but not grounded in reasoning.  
- Captions persist but semantic anchors drift apart.  
- Silent failure: no error is thrown, yet cross-modal grounding is gone.

## Open these first
- Cross-modal stability: [Alignment Drift](./alignment-drift.md)  
- Long-context melt: [Entropy Collapse](../MemoryLongContext/entropy-collapse.md)  
- Boundary checks: [Boundary Fade](./boundary-fade.md) *(planned)*  
- Retrieval schema: [Cross-Modal Trace](./cross-modal-trace.md)  
- State fences: [Memory Coherence](../MemoryLongContext/memory-coherence.md)

## Fix in 60 seconds
1. **Detect silence**  
   - Log presence/absence of `{text, visual, audio}` per turn.  
   - If any modality = null for >2 steps, flag as drop.

2. **Inject continuity token**  
   - Add `mod_keepalive` in the system schema to enforce recall of modality.  
   - Force echo of modality presence in every reasoning header.

3. **Re-anchor references**  
   - If image or audio missing, insert placeholder with `ΔS=skip` instead of null.  
   - Prevent collapse by keeping λ_observe convergent.

4. **Stabilize joins**  
   - Split by `{text | image | audio}` sections.  
   - Clamp cross-joins with BBAM to stop runaway drift.  

---

## Acceptance Targets
- **Coverage**: ≥ 0.70 for all active modalities.  
- **ΔS(question, retrieved)** ≤ 0.45 even when one modality drops.  
- **λ_observe** remains convergent across three paraphrases.  
- **No silent modality loss** beyond two turns.

## Copy-paste prompt

```txt
You are running TXTOS + WFGY Problem Map.

Symptom: modality vanished (text, image, or audio).  
Task: detect, re-anchor, and restore multimodal stability.

Protocol:
1. Log {text, visual, audio} presence each turn.
2. If any missing for >2 steps, insert placeholder `mod_keepalive`.
3. Require ΔS(question, retrieved) ≤ 0.45 across modalities.
4. Use BBAM for variance clamp, BBCR bridge if joins collapse.
5. Cite then answer; no orphan visual or audio references allowed.
