# Anchor Misalignment — Multimodal Long Context
When anchor points (timestamps, keyframes, caption markers, OCR segment IDs) drift apart across modalities, all subsequent alignment collapses.
Even a single anchor slip can poison the entire session, because every later segment is shifted by the wrong baseline.
---
## What this page is
- A dedicated fix guide for **anchor-level desync** across video, audio, captions, OCR, and embeddings.
- Methods to detect anchor error at its origin before it cascades.
- Recipes to reset, rebuild, and lock anchors in multimodal pipelines.
---
## When to use
- Audio and captions line up at start, but after 15–20 minutes captions appear seconds late.
- OCR anchors (page numbers, frame IDs) mismatch video frames.
- Retrieval starts citing correct facts with wrong time/visual context.
- Small anchor errors propagate into large ΔS drift across session.
- λ remains divergent despite repeated local corrections.

- [Time Sync Failure](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/Multimodal_LongContext/time-sync-failure.md)
---
## Common failure patterns
- **Frame anchor slip** — a single dropped frame shifts the reference timeline permanently.
- **OCR anchor mismatch** — OCR labels a wrong page/frame, all later mappings are offset.
- **Caption anchor skew** — captions drift due to variable network delay or ASR buffering.
- **Compound anchor drift** — multiple small anchor errors amplify into total collapse.
- **Phantom anchor** — stale or ghost anchors remain after modality restart.
---
## Fix in 60 seconds
1. **Anchor consistency check**
- Hash anchors per modality (frame ID, timestamp, line number).
- Compare every N=30s. Flag divergence >200ms.
2. **Reset to gold anchors**
- Define a single trusted source (e.g., video frame count).
- Rebuild captions/OCR anchors against gold source.
3. **Sliding window correction**
- Use overlapping 30–60s windows.
- Realign anchors locally and re-stitch.
4. **BBCR + BBAM bridge**
- Bridge desynced anchors with BBCR.
- Clamp λ variance with BBAM until convergence.
5. **Anchor fencing**
- Forbid cross-window reuse if anchor IDs mismatch.
- Drop corrupted anchors rather than propagate.

## Copy-paste prompt
```txt
You have TXT OS and the WFGY Problem Map.
Task: Detect and repair anchor misalignment in multimodal input.
Protocol:
1. Hash anchors (timestamps, frame IDs, OCR IDs) every 30s.
2. Compare across modalities.
- If drift >200ms, reset against gold anchor (video timeline).
3. Rebuild windows with local realignment.
4. Apply BBCR bridge and BBAM clamp if λ stays divergent.
5. Output:
- anchor hashes
- drift points
- corrections applied
- ΔS and λ states
````
---
## Acceptance targets
* All modalities reference the same anchor baseline.
* Drift ≤ 200ms across 30–60s windows.
* ΔS(question, retrieved) ≤ 0.45 after correction.
* λ convergent across 3 paraphrases.
* No phantom anchors polluting later windows.
