When context windows stretch to 50k–100k tokens or more, attention variance rises and the model smooths meaning.
|
||
This page shows how to detect entropy melt and repair reasoning before collapse spreads.
|
||
|

|
||
|
||
## When to use this page
|
||
- Dialogs degrade gradually as token count increases.
|
||
- Citations look correct but answers become vague or repetitive.
|
||
- Long technical transcripts lose specific numbers or symbols.
|
||
- Responses swing between over-detailed and generic filler.
|
||
- Reasoning chains stall after ~30–40 hops.
|
||
|
||
---
|
||
|
||
## Core acceptance targets
|
||
- ΔS(question, retrieved) ≤ 0.45 at each step.
|
||
- Retrieval coverage ≥ 0.70 to intended section.
|
||
- λ stays convergent across three paraphrases.
|
||
- Entropy (variance of attention weights) remains bounded.
|
||
- No collapse in chains ≤ 40 steps.
|
||
|
||
---
|
||
|
||
## Structural fixes
|
||
|
||
- **Measure entropy**
|
||
Track variance of attention weights across layers. Rising variance = early melt.
|
||
|
||
- **Clamp with BBAM**
|
||
Apply variance clamp when ΔS drifts upward or entropy rises beyond baseline.
|
||
|
||
- **Bridge with BBCR**
|
||
If reasoning halts, bridge to a stable anchor section and re-anchor the chain.
|
||
|
||
- **Shard long windows**
|
||
Split into `{system | task | snippets | answer}`. Enforce snippet fences per section.
|
||
|
||
- **Triangulate anchors**
|
||
Compare ΔS(question, anchor) vs ΔS(question, decoy). If close, re-chunk and re-embed.
|
||
|

|
||
|
||
## Fix in 60 seconds
|
||
1. **Probe entropy**
|
||
Compute variance of attention weights. Alert if variance > baseline by 20%.
|
||
|
||
2. **Apply BBAM**
|
||
Clamp variance. If ΔS ≥ 0.60, lock schema and retry.
|
||
|
||
3. **Anchor with BBCR**
|
||
If collapse detected, bridge back to known stable anchor node.
|
||
|
||
4. **Re-split context**
|
||
Force sections by `section_id`. Forbid cross-section reuse.
|
||
|
||
5. **Verify stability**
|
||
Expect ΔS(question, retrieved) ≤ 0.45, λ convergent, entropy flat.

## Copy-paste prompt
|
||
|
||
```
|
||
|
||
You have TXT OS and the WFGY Problem Map.
|
||
|
||
Goal: Detect and repair entropy collapse in long contexts.
|
||
|
||
Protocol:
|
||
|
||
1. Compute ΔS(question, retrieved).
|
||
2. Report entropy variance vs baseline.
|
||
3. If variance ↑ or ΔS ≥ 0.60:
|
||
|
||
* Apply BBAM to clamp
|
||
* If reasoning halts, use BBCR to bridge anchor
|
||
4. Split prompts by section, forbid cross-section reuse.
|
||
5. Report:
|
||
|
||
* ΔS(question, retrieved)
|
||
* entropy variance
|
||
* λ states (retrieve, assemble, reason)
|
||
* final answer with citations
|
||
|
||
```

||
## Common failure patterns
|
||
- **Entropy melt**: answers flatten to “it depends…” filler.
|
||
- **Boundary blur**: context merges across joins, citations misalign.
|
||
- **Long-chain stall**: after 30+ hops, λ flips divergent.
|
||
- **Ghost repetitions**: same phrase reappears across sections.
