|
||
|
||
When multimodal long-context windows extend, **boundaries between modalities or section joins blur**.
|
||
This causes models to conflate captions, transcripts, or visuals across neighboring regions, producing hybrid outputs or lost anchors.
|
||
|
||
---
|
||
|
||
## Symptoms of Boundary Fade
|
||
- Captions merge into adjacent paragraphs, citations drift by a few lines.
|
||
- Visual snippets spill across sections, losing clear demarcation.
|
||
- ΔS across joins rises above 0.50, meaning semantic leakage.
|
||
- Output shows partial traces of two anchors instead of one.
|
||
- “Memory fade” across session restarts, context joins feel smeared.

||

|
||
## Fix in 60 seconds
|
||
1. **Measure joins**
|
||
- Compute ΔS across each modality join. Threshold ≤ 0.50.
|
||
- If higher, suspect boundary fade.
|
||
|
||
2. **Enforce fences**
|
||
- Insert `{section_start}` and `{section_end}` markers explicitly.
|
||
- Require `mod_type` label (e.g., `[image]`, `[caption]`, `[audio]`).
|
||
|
||
3. **Stabilize variance**
|
||
- Apply BBAM clamp when variance spikes near joins.
|
||
- Use BBCR bridge to redirect reasoning back to the intended anchor.
|
||
|
||
4. **Audit output**
|
||
- Each snippet must map to a single anchor ID.
|
||
- Reject blended outputs that merge two snippet IDs.
|
||
|

|
||
|
||
## Acceptance Targets
|
||
- ΔS(question, retrieved) ≤ 0.45 overall.
|
||
- ΔS across joins ≤ 0.50.
|
||
- λ_observe convergent across three paraphrases.
|
||
- No section bleed: one snippet → one anchor only.

## Copy-paste prompt
|
||
|
||
```txt
|
||
You are running TXTOS + WFGY Problem Map.
|
||
|
||
Symptom: section or modality boundaries blur (“boundary fade”).
|
||
|
||
Protocol:
|
||
1. Compute ΔS across joins, enforce ≤ 0.50.
|
||
2. Insert section_start and section_end markers.
|
||
3. Require mod_type labels for all snippets.
|
||
4. Apply BBAM clamp, BBCR bridge if joins collapse.
|
||
5. Verify each snippet maps to exactly one anchor ID.
