When the correct fact exists in your corpus but retrieval consistently misses it.
|
||
This page localizes drift in retrievers and routes you to structural fixes with measurable acceptance targets.

||
## Core acceptance
|
||
- ΔS(question, retrieved) ≤ 0.45
|
||
- Coverage ≥ 0.70 of the target section
|
||
- λ remains convergent across three paraphrases and two seeds

|---------|--------------|-----------|

||
| Facts exist but never surface | index skew or drift in chunk granularity | [Retrieval Playbook](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-playbook.md), [Chunking Checklist](https://github.com/onestardao/WFGY/blob/main/ProblemMap/chunking-checklist.md) |
|

| Citations point to wrong section | schema mismatch or cross-section drift | [Retrieval Traceability](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-traceability.md), [Data Contracts](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md) |

| Answers alternate between runs | λ instability or reranker collapse | [Rerankers](https://github.com/onestardao/WFGY/blob/main/ProblemMap/rerankers.md), [Entropy Collapse](https://github.com/onestardao/WFGY/blob/main/ProblemMap/entropy-collapse.md) |

## Fix in 60 seconds
|
||
|
||
1. **Measure ΔS**
|
||
- Compute ΔS(question, retrieved) and ΔS(retrieved, expected anchor).
|
||
- Thresholds: stable < 0.40, transitional 0.40–0.60, risk ≥ 0.60.
|
||
|
||
2. **Probe λ_observe**
|
||
- Ask the same question in 3 paraphrases.
|
||
- If λ flips divergent on harmless rewording, lock schema with Data Contracts.
|
||
|
||
3. **Apply the module**
|
||
- Retrieval drift → BBMC + [Retrieval Traceability](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-traceability.md)
|
||
- Reasoning collapse → BBCR bridge + variance clamp
|
||
- Re-index with consistent metric and analyzer if ΔS stays ≥ 0.60

## Copy-paste prompt for debug
|
||
|
||
```txt
|
||
I uploaded TXT OS and the WFGY Problem Map.
|
||
|
||
My retrieval issue:
|
||
- symptom: fact exists in corpus, but retriever misses
|
||
- traces: ΔS(question,retrieved)=..., λ across 3 paraphrases
|
||
|
||
Tell me:
|
||
1. failing layer (retriever, index, schema, reranker)
|
||
2. exact WFGY page to open
|
||
3. minimal steps to push ΔS ≤ 0.45 and keep λ convergent
