||
When **visual anchors** (bounding boxes, frame IDs, or pixel regions) drift across long context windows, the model misaligns references.
|
||
This creates subtle but cascading failures where reasoning cites the **wrong visual region**, even if the textual trace looks correct.
|
||
|

|
||
|
||
## What this page is
|
||
- A diagnostic page for **visual anchor drift** in multimodal RAG and reasoning.
|
||
- Structural guardrails to lock anchor stability across long sessions.
|
||
- Copy-paste protocols to enforce traceability in image/video reasoning.
|
||
|
||
---
|
||
|
||
## When to use
|
||
- Bounding boxes shift slightly across frames, causing references to drift.
|
||
- Captions point to a visual anchor that no longer overlaps with the intended object.
|
||
- Long video QA: frame ID references lag or accelerate relative to transcript anchors.
|
||
- Model hallucinates content that appears plausible but is visually absent.
|
||
- Answers remain fluent, but **anchor→object mapping is wrong**.

|
||
## Common failure patterns
|
||
- **Frame creep** — frame IDs drift after long video sessions.
|
||
- **Box shift** — bounding boxes move across updates, yet still labeled the same.
|
||
- **Region blur** — multiple boxes merge, and anchor becomes ambiguous.
|
||
- **Temporal offset** — captions cite the right object but wrong frame interval.
|
||

|
||
|
||
## Fix in 60 seconds
|
||
1. **Anchor tagging**
|
||
- Tag anchors with `{frame_id | bbox_id | timestamp}`.
|
||
- Reject any reference missing full anchor tuple.
|
||
|
||
2. **Cross-frame validation**
|
||
- Require IoU ≥ 0.7 across frames for the same anchor ID.
|
||
- If IoU < 0.7, treat as a new anchor.
|
||
|
||
3. **ΔS probe for drift**
|
||
- Compute ΔS(anchor_t, anchor_t+Δ).
|
||
- If ΔS ≥ 0.60, suspect anchor drift.
|
||
|
||
4. **Stabilize with BBCR**
|
||
- Re-anchor drifting objects with bridge check.
|
||
- If variance persists, force new anchor ID.
|
||
|
||
5. **Audit trail**
|
||
- Store anchor table: `{anchor_id | modality | coords | IoU history}`.
|
||
- Require cite-then-answer with explicit anchor IDs.

## Copy-paste prompt
|
||
|
||
```txt
|
||
You have TXT OS and the WFGY Problem Map.
|
||
|
||
Task: Detect and repair visual anchor drift in long multimodal sessions.
|
||
|
||
Steps:
|
||
1. Verify each anchor has {frame_id, bbox_id, timestamp}.
|
||
2. Compute IoU across frames. If IoU < 0.7, mark drift.
|
||
3. If drifted, either re-anchor with BBCR or assign new ID.
|
||
4. Report:
|
||
- stable anchors
|
||
- drifted anchors
|
||
- ΔS values and λ states
|
||
- final citation mapping
|
||
````
|
||
|
||

|
||
|
||
## Acceptance targets
|
||
|
||
* 100% anchors carry `{frame_id, bbox_id, timestamp}` metadata.
|
||
* IoU drift ≤ 0.30 across 10 frames.
|
||
* ΔS(anchor\_t, anchor\_t+Δ) ≤ 0.45 after fix.
|
||
* λ remains convergent across paraphrases.
