|
||
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.

|

|
||
## 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.
