When multimodal systems run across long contexts, sometimes **the same visual, caption, or audio snippet gets echoed back repeatedly** instead of advancing reasoning.  
This creates “semantic stutter” where the model hallucinates progress but actually cycles on stale content.

---

## Symptoms of Echo Loop
- Captions or transcripts repeated across multiple turns without update.  
- Visual or audio reference echoed verbatim despite new input.  
- Model appears to “stall” on the same anchor, ignoring user’s next steps.  
- ΔS values stay flat across paraphrases, indicating semantic freeze.  
- Users perceive output as verbose filler with no new reasoning.

## Open these first
- Attention variance clamp: [Entropy Collapse](../MemoryLongContext/entropy-collapse.md)  
- Context drift and chain failure: [Context Drift](../MemoryLongContext/context-drift.md)  
- Cross-modal sync hazards: [Sync Loop](./sync-loop.md)  
- Traceability schema: [Cross-Modal Trace](./cross-modal-trace.md)  
- Session fences: [Memory Coherence](../MemoryLongContext/memory-coherence.md)

## Fix in 60 seconds
1. **Detect stutter**  
   - If identical snippet ID repeats >2 times without anchor update, flag echo-loop.  
   - Log ΔS and λ across three turns; flat line = freeze.

2. **Force anchor refresh**  
   - Require `anchor_rev++` with each new modality.  
   - If missing, insert continuity token `mod_refresh`.

3. **Break the loop**  
   - Clamp with BBAM to suppress repeated variance.  
   - Insert BBCR bridge node to force new semantic branch.  

4. **Audit citations**  
   - Require unique snippet IDs in each new step.  
   - If repeated without anchor shift, reject and re-request content.  

---

## Acceptance Targets
- ΔS(question, retrieved) ≤ 0.45, with downward slope across steps.  
- No modality snippet echoed more than twice consecutively.  
- λ_observe convergent across three paraphrases.  
- Anchor IDs strictly monotonic (`anchor_rev` increments).

## Copy-paste prompt

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

Symptom: repeated captions or snippets, model is “stuck in loop.”

Protocol:
1. Detect repeats >2 turns → flag echo-loop.
2. Require anchor_rev increment per modality.
3. Insert mod_refresh token if anchor missing.
4. Apply BBAM clamp and BBCR bridge to break loop.
5. Verify ΔS downward trend across turns.
