# Modality Swap — Multimodal Long Context
|
||
|
||
When inputs from different modalities are accidentally swapped or misrouted (e.g., OCR output fed into caption pipeline, audio transcript aligned as video metadata), the entire reasoning chain collapses.
|
||
This is one of the hardest multimodal errors to debug because every modality appears syntactically correct, but the semantic anchors belong to the wrong channel.
|
||
|
||
---
|
||
|
||
## What this page is
|
||
- A focused repair guide for **cross-modality swap failures**.
|
||
- How to detect modality swaps early with structural probes.
|
||
- Guardrails to prevent silent misrouting across long-context pipelines.
|
||
|
||
---
|
||
|
||
## When to use
|
||
- Captions look valid textually but describe a different video segment.
|
||
- OCR transcript shows inside the "caption" stream, while actual captions disappear.
|
||
- Audio embeddings drift sharply while ΔS remains low inside the wrong modality.
|
||
- Model answers flip between describing visuals vs. reading text.
|
||
- Citations remain “correct” but belong to the wrong modality (e.g., frame vs. page).

## Common failure patterns
|
||
- **OCR → Caption swap** — OCR text injected as subtitle stream.
|
||
- **Audio → Metadata swap** — ASR transcript stored as document metadata.
|
||
- **Caption → OCR swap** — time-stamped captions parsed into wrong page references.
|
||
- **Silent multimodal swap** — all channels populated, but semantically wrong modality.
|
||
- **Chained swap amplification** — one early swap causes fusion to fail downstream.

||

|
||
## Fix in 60 seconds
|
||
1. **Fingerprint each modality**
|
||
- Compute embedding signatures separately for OCR, audio, caption, and visual frames.
|
||
- Verify signatures match expected modality domain.
|
||
|
||
2. **Cross-modality consistency check**
|
||
- Compare OCR tokens vs. caption words vs. audio transcript.
|
||
- If overlap >50%, suspect swap.
|
||
|
||
3. **Re-map against anchor modality**
|
||
- Use video timeline or gold reference as ground truth.
|
||
- Re-align swapped data to the correct channel.
|
||
|
||
4. **Apply BBPF + BBCR**
|
||
- Use BBPF (pathfinder) to re-thread the swapped modality.
|
||
- Use BBCR bridge to anchor swapped stream back into context.
|
||
|
||
5. **Fence schema**
|
||
- Enforce explicit modality tags `{OCR|Caption|Audio|Visual}` in contracts.
|
||
- Forbid ingestion without modality ID.

## Copy-paste prompt

```txt

You have TXT OS and the WFGY Problem Map.

|
||
Task: Detect and correct modality swap in multimodal data.
|
||
|
||
Steps:
|
||
1. Fingerprint each modality stream.
|
||
2. Compare OCR vs Caption vs Audio for abnormal overlap.
|
||
3. If swap detected:
|
||
- Re-map data back to correct modality based on anchors.
|
||
- Apply BBPF + BBCR to stabilize reasoning.
|
||
4. Output:
|
||
- modality checks
|
||
- suspected swaps
|
||
- corrected alignment
|
||
- ΔS and λ states

||
## Acceptance targets
|
||
|
||
* No cross-modality overlap >20% except at validated joins.
|
||
* ΔS(question, retrieved) ≤ 0.45 after swap repair.
|
||
* λ convergent across paraphrases.
|
||
* Explicit modality tags enforced in every schema contract.
|
||
* Zero “silent swaps” propagate beyond first ingestion stage.
