Context Drift — Long Reasoning Chain Instability

🧭 Quick Return to Map

You are in a sub-page of MemoryLongContext.
To reorient, go back here:

Think of this page as a desk within a ward.
If you need the full triage and all prescriptions, return to the Emergency Room lobby.

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.
