When cross-modal reasoning depends on a **semantic anchor** (e.g., a labeled frame, a highlighted phrase, or an OCR-extracted region),
|
||
anchors can drift or flip over long context. This leads to citations that *look right* but carry shifted meaning,
|
||
causing hallucinations or inverted reasoning.
|
||
|

|
||
|
||
## What this page is
|
||
- A compact guardrail for **anchor stability** in multimodal reasoning.
|
||
- Ensures each anchor keeps the same semantic reference across hops and long windows.
|
||
- Provides ΔS and λ checkpoints to detect when anchors silently slide.
|
||
|
||
---
|
||
|
||
## When to use
|
||
- OCR region ID points to the right box, but interpretation drifts to adjacent text.
|
||
- Video anchor “frame 123” drifts to “frame 125” after long-window fusion.
|
||
- Captions or bounding boxes shift slightly, making evidence sound correct but semantically false.
|
||
- Retrieval still fetches the right object, but reasoning cites it in the wrong relation.
|
||
- QA answers reference the correct modality but with swapped or outdated anchor.

|
||
## Common failure patterns
|
||
- **Offset drift** — anchor IDs increment or decrement subtly over long windows.
|
||
- **Semantic slide** — anchor refers to the same token span, but meaning shifts with context.
|
||
- **Anchor bleed** — citation points leak into neighboring regions.
|
||
- **Temporal skew** — audio timestamp anchor lags behind the cited video frame.
|
||

|
||
|
||
## Fix in 60 seconds
|
||
1. **Anchor schema lock**
|
||
- Require `{anchor_id, modality, offsets, checksum}` for each citation.
|
||
- Enforce immutability across hops.
|
||
|
||
2. **ΔS anchor probe**
|
||
- Compare ΔS(anchor, retrieved) at every window refresh.
|
||
- Alert if ΔS rises above 0.50.
|
||
|
||
3. **λ stability check**
|
||
- Record λ at anchor → fusion → reasoning.
|
||
- Divergence indicates hidden drift.
|
||
|
||
4. **Re-anchor on drift**
|
||
- If ΔS ≥ 0.60 or λ diverges, fetch anchor metadata again.
|
||
- Use checksum or hash to validate identity.
|
||
|
||
5. **Bridge recovery**
|
||
- Apply BBCR to rebuild chain with corrected anchors.
|
||
- Require re-citation before output.

## Copy-paste prompt

You have TXT OS and the WFGY Problem Map.
|
||
|
||
Task: Detect and repair semantic anchor shift.
|
||
|
||
Steps:
|
||
1. List all anchors with {anchor_id, modality, offsets}.
|
||
2. Compute ΔS(anchor, retrieved) at each long-context step.
|
||
3. If ΔS ≥ 0.50 or λ diverges, trigger anchor refresh.
|
||
4. Rebuild reasoning chain with corrected anchors.
|
||
5. Output must include anchor list, ΔS values, λ states, and corrected citations.

|
||
|
||
## Acceptance targets
|
||
|
||
* ΔS(anchor, retrieved) ≤ 0.45 across all steps.
|
||
* λ remains convergent across three paraphrases.
|
||
* No anchor bleed, drift, or temporal skew across modalities.
|
||
* Every anchor carries stable semantic meaning from start to final answer.
