# Spatial Fusion Error — Multimodal Long Context

When **spatial information from different modalities** (text, image, video, 3D layout) is fused incorrectly,  
the model builds a distorted scene map. This results in answers that are locally fluent but spatially wrong.

---

## What this page is
- A repair map for **spatial mis-fusion** across long multimodal windows.  
- Structural checks that keep anchors aligned in 2D/3D space.  
- Copy-paste prompts to enforce spatial traceability in multimodal RAG.

---

## When to use
- Text says "object A is left of object B" but visual encoder aligns them oppositely.  
- Bounding boxes overlap or merge, losing spatial independence.  
- 3D → 2D projection mismatch: captions reference an object that isn’t in frame.  
- Video QA drifts: same entity appears in different spots across time.  
- Answers mention correct objects but wrong **spatial relations** (left/right, inside/outside, above/below).

---

## Common failure patterns
- **Axis flip** — left/right or up/down swapped.  
- **Projection drift** — 3D object references collapse to wrong 2D bounding box.  
- **Overlap collapse** — two entities share the same spatial slot.  
- **Cross-modal mismatch** — text anchor doesn’t correspond to visual bounding box.  

---

## Fix in 60 seconds
1. **Spatial schema lock**  
   - Represent anchors as `{id, coords(x,y,z), frame_id}`.  
   - Reject answers missing explicit spatial schema.

2. **ΔS probe across modalities**  
   - Compute ΔS(text_anchor, visual_anchor).  
   - If ΔS ≥ 0.60, suspect fusion error.

3. **Spatial IoU check**  
   - Enforce IoU ≥ 0.7 for same anchor across modalities.  
   - If < 0.7, assign new anchor ID.

4. **Stabilize with BBCR**  
   - Bridge text ↔ visual mismatch with constraint re-anchoring.  
   - Clamp variance with BBAM.

5. **Trace audit**  
   - Log `{anchor_id, modality, coords, IoU}`.  
   - 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 spatial fusion errors across modalities.

Steps:
1. Verify each anchor has {id, coords(x,y,z), frame_id}.
2. Compute IoU across modalities. If IoU < 0.7, treat as mismatch.
3. Probe ΔS across text and visual anchors.
4. Apply BBCR if drift detected, else assign new ID.
5. Return:
   - stable anchors
   - mismatched anchors
   - ΔS values and λ states
   - corrected spatial map
````

## Acceptance targets

* 100% anchors represented with explicit `{id, coords, frame_id}`.
* Cross-modal IoU ≥ 0.7 after fix.
* ΔS(text, visual) ≤ 0.45.
* λ remains convergent across paraphrases.
* No axis flip errors across test prompts.
