A compact field guide to stabilize Gemini calls inside RAG, agents, or long workflows. Use the checks below to localize failure, then jump to the exact WFGY fix page.

## Core acceptance
- ΔS(question, retrieved) ≤ 0.45
- Coverage ≥ 0.70 for the target section
- λ remains convergent across 3 paraphrases
- E_resonance stable on long windows

## Typical breakpoints and the right fix

| Symptom you see | Likely cause | Fix page |
|---|---|---|
| High similarity yet wrong meaning | Metric or index mismatch | [Embedding ≠ Semantic](https://github.com/onestardao/WFGY/blob/main/ProblemMap/embedding-vs-semantic.md) |
| Gemini cites the wrong paragraph | Chunk boundaries and trace loss | [Hallucination](https://github.com/onestardao/WFGY/blob/main/ProblemMap/hallucination.md), [Retrieval Traceability](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-traceability.md) |
| Answers flip across runs | λ instability on long threads | [Context Drift](https://github.com/onestardao/WFGY/blob/main/ProblemMap/context-drift.md), [Entropy Collapse](https://github.com/onestardao/WFGY/blob/main/ProblemMap/entropy-collapse.md) |
| Refuses or loops on safe content | Prompt contract not locked | [Data Contracts](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md) |
| Good recall but bad ordering | Reranking missing | [Rerankers](https://github.com/onestardao/WFGY/blob/main/ProblemMap/rerankers.md) |
| Corrected errors reappear | Re-entry without variance clamp | [pattern_hallucination_reentry.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/patterns/pattern_hallucination_reentry.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 with λ_observe**
- Vary k ∈ {5, 10, 20}. Flat high curve means metric or index mismatch.
- Reorder prompt headers. If ΔS spikes, lock the schema.

3) **Apply the module**
- Retrieval drift → BBMC + Data Contracts.
- Reasoning collapse → BBCR bridge + BBAM variance clamp.
- Dead ends in long runs → BBPF alternate path with explicit step limits.

4) **Verify**
- Coverage ≥ 0.70 on the target section.
- Three paraphrases keep ΔS ≤ 0.45 and λ convergent.
- Re-run with seed change and shuffled snippet order.

## Gemini-specific gotchas

- **Tool and JSON calls**  
  If the function schema is loose, Gemini may hallucinate fields. Lock schemas with [Data Contracts](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md) and clamp variance with BBAM.

- **Safety flips on neutral text**  
  When the role block is not pinned, safety can overfire. Use a citation-first header from [Retrieval Traceability](https://github.com/github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-traceability.md) and keep source boundaries explicit.

- **Hybrid retrieval regressions**  
  HyDE plus keyword can split queries. Check [pattern_query_parsing_split.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/patterns/pattern_query_parsing_split.md) and add a stable anchor paragraph to reduce drift.

- **Long context smear**  
  Large windows flatten meaning if chunks are not semantic. Rebuild with the [chunking checklist](https://github.com/onestardao/WFGY/blob/main/ProblemMap/chunking-checklist.md) and verify joins with ΔS probes.

## Copy-paste prompt (safe)

```

read the WFGY TXT OS and Problem Map pages. extract ΔS, λ\_observe, E\_resonance and modules BBMC, BBPF, BBCR, BBAM.
given my gemini failure:

* symptom: \[brief]
* traces: \[ΔS(question, retrieved)=…, ΔS(retrieved, anchor)=…, λ states]

tell me:

1. which layer fails and why,
2. which fix page to open from this repo,
3. the minimal steps to push ΔS ≤ 0.45 and keep λ convergent,
4. how to verify with a reproducible test.

```

## Escalation path

- Index or metric mismatch that stays flat after k sweeps → rebuild embeddings and check [Vectorstore Fragmentation](https://github.com/onestardao/WFGY/blob/main/ProblemMap/patterns/pattern_vectorstore_fragmentation.md).
- Agent tools fighting each other → see [Multi-Agent Problems](https://github.com/onestardao/WFGY/blob/main/ProblemMap/Multi-Agent_Problems.md) and split memory namespaces.
- First prod call fails after deploy → check [Pre-Deploy Collapse](https://github.com/onestardao/WFGY/blob/main/ProblemMap/predeploy-collapse.md) and [Bootstrap Ordering](https://github.com/onestardao/WFGY/blob/main/ProblemMap/bootstrap-ordering.md).
