Tiny offsets between modalities (audio, captions, video frames, OCR text) may start small but amplify over long windows.
This creates compounding errors, unstable retrieval, and reasoning collapse even if each modality alone looks healthy.
---
## What this page is
- A targeted fix for error propagation in multimodal pipelines.
- Practical checks to detect amplification before catastrophic drift.
- Guardrails and recipes to realign channels across long-context sessions.
---
## When to use
- Captions and audio drift apart by seconds after long playbacks.
- OCR timestamps no longer align with video frames.
- QA answers start citing mismatched visual and transcript snippets.
- ΔS is acceptable at local scale but grows uncontrollably across joins.
- λ flips between convergent and divergent when multiple modalities are combined.

## Common failure patterns
- **Frame slip**: video and captions drift one frame every N seconds, gap grows over minutes.
- **Transcript echo**: OCR or ASR repeats or skips blocks, creating compounding offsets.
- **Modal desync cascade**: one channel’s offset propagates into retrieval ranking and pollutes others.
- **ΔS climb**: segment-wise ΔS stays <0.45, but across the whole sequence ΔS >0.70.
- **Cumulative hallucination**: small errors accumulate, eventually flipping meaning entirely.
---
## Fix in 60 seconds
1. **Windowed checkpoints**
- Insert alignment anchors every N=30–60s.
- Reset offsets relative to anchors instead of carrying drift forward.
2. **Cross-hash audit**
- Compute rolling hash across each modality.
- If hashes diverge at the same index repeatedly, clamp with trace.
3. **ΔS slope monitor**
- Track ΔS growth across windows.
- If slope ≥ +0.05 per window, trigger correction.
4. **Realign with BBCR bridge**
- Use bridging nodes to pull all modalities back to anchor.
- Apply BBAM variance clamp if λ keeps flipping.
5. **Escalate when unstable**
- If ΔS ≥ 0.60 or λ stays divergent across 3 checks, abort merge and isolate channels.

## Copy-paste prompt
```txt
You have TXT OS and the WFGY Problem Map.
Task: Detect and fix desync amplification across multimodal inputs.
Protocol:
1. Insert anchors every 30–60s and reset offsets.
2. Compute rolling hash per modality and check drift.
3. Track ΔS slope across windows.
- If slope ≥ +0.05, trigger correction.
4. Apply BBCR bridge for re-alignment.
5. Clamp λ variance with BBAM.
6. Output:
- anchor points
- ΔS history
- λ states
- correction actions taken
````

## Acceptance targets
* ΔS(question, retrieved) ≤ 0.45 across session.
* ΔS slope ≤ +0.02 per window after correction.
* λ remains convergent across 3 paraphrases after anchors.
* All modalities map back to common anchor with ≤ 200ms drift.
* No session collapses into hallucination due to cumulative errors.
