# Context Drift — Long Reasoning Chain Instability

When reasoning spans 20–40 hops or more, attention shifts accumulate and context drifts.  
This page explains how to diagnose λ divergence, stabilize reasoning chains, and repair collapsed context.

---

## When to use this page
- Long reasoning plans (~20+ steps) start with logic but later flip or contradict.  
- Multi-agent workflows repeat or miss earlier facts.  
- Citations remain valid, but final answers drift from original question.  
- λ flips divergent after harmless paraphrases.  
- Answers alternate between runs with identical inputs.

---

## Core acceptance targets
- ΔS(question, retrieved) ≤ 0.45  
- Retrieval coverage ≥ 0.70 for target section  
- λ remains convergent across three paraphrases  
- Chain length stable up to 40 hops without collapse  
- Entropy variance remains bounded in mid-to-late steps  

---

## Structural fixes

- **Three-paraphrase probe**  
  Re-ask the same question three ways. Log ΔS and λ at each hop.  
  If λ flips, schema is unstable.

- **Clamp with BBAM**  
  Apply variance clamp when λ flips across harmless paraphrases.

- **Bridge with BBCR**  
  Insert bridge nodes when long chains stall. Anchor back to earlier stable nodes.

- **Enforce snippet fences**  
  Require each reasoning step cite snippet_id. Forbid cross-section reuse.

- **Re-anchor with anchors**  
  Compare ΔS(question, anchor) vs ΔS(question, decoy).  
  If ΔS is close, re-chunk corpus.

---

## Fix in 60 seconds
1. **Log ΔS and λ** across 3 paraphrases.  
2. **Clamp** with BBAM if λ flips.  
3. **Bridge** with BBCR if reasoning halts.  
4. **Re-anchor** using anchor triangulation.  
5. **Verify** coverage ≥ 0.70 and ΔS ≤ 0.45.

## Copy-paste prompt

```

You have TXT OS and the WFGY Problem Map.

Goal: Detect and repair context drift in long reasoning chains.

Protocol:

1. Ask the same question three ways.
2. Log ΔS(question, retrieved) for each.
3. Log λ states across all hops.
4. If λ flips:

   * Apply BBAM clamp.
   * If reasoning stalls, apply BBCR and anchor bridge.
5. Require snippet\_id at each step.
6. Report:

   * ΔS(question, retrieved)
   * λ states across paraphrases
   * bridge nodes inserted
   * final answer with citations

```

## Common failure patterns
- **Chain stall**: reasoning halts after ~25–30 hops.  
- **Paraphrase drift**: harmless rewordings flip λ.  
- **Repeating answers**: earlier snippets loop back with filler.  
- **Contradictions**: late chain contradicts early reasoning.
