When retry logic or auto-synchronization between modalities (audio, video, OCR, captions) gets stuck in an infinite loop, sessions stall, consume resources, and never converge.
This page defines guardrails to detect, prevent, and break sync loops in multimodal long-context systems.
---
## What this page is
- A structural fix for infinite retry and deadlock cycles in multimodal sync.
- Practical acceptance checks for loop detection and controlled escape.
- A minimal recovery recipe to restore alignment without drift.
---
## When to use
- OCR retries indefinitely while video/audio remain stable.
- Captions stream pauses and replays the same segment repeatedly.
- Audio transcripts re-ingest the same block, causing ΔS to climb instead of stabilize.
- Logs show identical hashes across retries without progress.
- λ oscillates between divergent and convergent without resolution.

---
## Common failure patterns
- **Infinite retry loop**: system replays missing modality forever.
- **Hash-stable stall**: every loop produces identical snippet hashes with no progress.
- **Cross-modal ping-pong**: audio requests OCR, OCR requests audio, cycle never ends.
- **Entropy rise**: ΔS climbs steadily while λ flips back and forth.
- **Dead channel masking**: one modality gone but loop hides it under retries.
---
## Fix in 60 seconds
1. **Retry cap**
- Hard stop after N retries (suggest N=3).
- Escalate instead of looping silently.
2. **Hash-change check**
- Compute `hash(step_output)`.
- If 3 consecutive retries produce identical hash, break loop.
3. **ΔS watchdog**
- Monitor ΔS across retries.
- If ΔS ≥ 0.60 after N attempts, abort and request operator fix.
4. **Loop breaker**
- Apply BBPF (Bridge by Parallel Fork) to inject alternate path.
- Bridge surviving modalities to bypass missing channel.
5. **Escalation**
- Emit `loop_detected=true`, record trace.
- Provide missing modality report.

## Copy-paste prompt
```txt
You have TXT OS and the WFGY Problem Map.
Task: Detect and break sync loops in multimodal pipelines.
Protocol:
1. Track retries per modality (audio, video, OCR, captions).
2. If retries > 3 OR identical hash repeats, break loop.
3. Probe ΔS across retries:
- If ΔS ≥ 0.60, abort and mark loop_detected.
4. Apply BBPF bridge to surviving modalities.
5. Return report:
- retries attempted
- ΔS history
- λ states
- missing modality
- loop_detected flag
````
---
## Acceptance targets
* No retry exceeds N=3 without escalation.
* ΔS(question, retrieved) ≤ 0.45 after loop resolved.
* λ convergent across 3 paraphrases after recovery.
* Trace log shows explicit `loop_detected` when triggered.
* System never stalls indefinitely.
