|
||
When one or more modalities silently fail (audio muted, video frames dropped, OCR blank), the pipeline continues but reasoning collapses.
|
||
This page defines structural fixes to detect missing modalities and keep alignment stable.
|
||
|
||
---
|
||
|
||
## What this page is
|
||
- A checklist to prevent silent failures when audio, video, or OCR signals disappear.
|
||
- Guardrails to stop reasoning collapse when modality coverage < 100%.
|
||
- Restart-stable fallback protocols.
|
||
|
||
---
|
||
|
||
## When to use
|
||
- Video stream plays but no OCR text appears.
|
||
- Audio-only retrieval answers correctly but loses citation anchors.
|
||
- Captions missing for long segments, leading to hallucinated content.
|
||
- Multimodal agent switches seed and one modality never returns.
|
||
- Logs show ΔS curve flat but λ diverges (sign of missing channel).

|
||
|
||
## Common failure patterns
|
||
- **Silent dropout**: modality returns empty payloads but pipeline continues.
|
||
- **Asymmetric collapse**: audio fine but OCR missing causes reasoning drift.
|
||
- **Chain break**: captions absent → no anchor for reasoning step.
|
||
- **Overcompensation**: model hallucinates filler text to patch missing modality.
|
||
- **Seed skew**: one seed includes OCR, another does not.
|
||
|
||
---
|
||
|
||
## Fix in 60 seconds
|
||
1. **Heartbeat check**
|
||
- Require each modality to emit a `ready=true` signal every 5s.
|
||
- If missing, flag dropout immediately.
|
||
|
||
2. **Coverage metric**
|
||
- Compute `coverage_ratio = active_modalities / expected_modalities`.
|
||
- Threshold: coverage ≥ 0.95 required.
|
||
|
||
3. **Dropout handler**
|
||
- If dropout detected, freeze ΔS probe.
|
||
- Apply BBCR bridge to reconnect.
|
||
- If not recoverable, short-circuit and request missing data.
|
||
|
||
4. **Fallback policy**
|
||
- Lock reasoning to available modalities.
|
||
- Explicitly annotate missing modality (`ocr_missing=true`).
|
||
- Never hallucinate absent channels.
|
||
|
||
5. **Restart stability**
|
||
- Verify across 3 seeds that all modalities return.
|
||
- If any seed fails, escalate.

## Copy-paste prompt
|

|
||
```txt
|
||
You have TXT OS and the WFGY Problem Map.
|
||
|
||
Task: Detect and repair modality dropout.
|
||
|
||
Protocol:
|
||
1. Require audio, video, OCR all declare `ready=true`.
|
||
2. Compute coverage_ratio. If < 0.95, flag dropout.
|
||
3. If dropout:
|
||
- freeze ΔS probe
|
||
- re-anchor with BBCR bridge
|
||
- annotate missing modalities explicitly
|
||
4. Return:
|
||
- coverage ratio
|
||
- ΔS and λ states
|
||
- anchor stability
|
||
- missing modality report

|
||
## Acceptance targets
|
||
|
||
* Coverage ≥ 95% across expected modalities.
|
||
* ΔS(question, retrieved) ≤ 0.45 when all active modalities align.
|
||
* λ remains convergent across 3 paraphrases.
|
||
* No hallucinated filler in place of missing modality.
|
||
* Restart: 3 seeds show identical active modality set.
