A compact field guide for Gemini on Vertex AI. Use this page when failures look provider specific. The checks route you to the exact WFGY fix page and give a minimal recipe you can paste into your runbook.

|
||
**Core acceptance**
|
||
|
||
- ΔS(question, retrieved) ≤ 0.45
|
||
- coverage ≥ 0.70 for the target section
|
||
- λ remains convergent across 3 paraphrases and 2 seeds

||
## 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. If ΔS goes flat high, suspect index or metric 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.
|
||
- Safety or tool-call stalls → BBPF alternate path with explicit timeouts.
|
||
|
||

|
||
|
||
## Typical breakpoints and the right fix
|
||
|
||
- **Safety filters block or rewrite**
|
||
- Symptom: answer disappears or becomes generic; logs show blocked categories.
|
||
- Fix path: keep the request task-bound and citation-first. Apply [Data Contracts](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md) and a BBCR bridge that states lawful scope and cites sources. Verify with [Retrieval Traceability](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-traceability.md).
|
||
|
||
- **Tool call returned “no function call” despite valid tools**
|
||
- Symptom: model narrates instead of calling the function; JSON keys omitted.
|
||
- Fix path: lock the tool schema in the prompt header using [Data Contracts](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md). Add BBPF fallback branch that emits the same call with minimal args when λ flips.
|
||
|
||
- **Streaming truncation or partial JSON**
|
||
- Symptom: closing braces missing or content clipped.
|
||
- Fix path: BBAM variance clamp on output length and a post-validator that re-asks only for the missing tail. If loops appear, follow [Logic Collapse](https://github.com/onestardao/WFGY/blob/main/ProblemMap/logic-collapse.md).
|
||
|
||
- **Hybrid retrieval worse than single retriever**
|
||
- Symptom: HyDE + BM25 underperform and top-k is noisy.
|
||
- Fix path: apply the split pattern and retune as in [Query Parsing Split](https://github.com/onestardao/WFGY/blob/main/ProblemMap/patterns/pattern_query_parsing_split.md). Then re-order with [Rerankers](https://github.com/onestardao/WFGY/blob/main/ProblemMap/rerankers.md).
|
||
|
||
- **Indexed facts never show up**
|
||
- Symptom: high recall offline, zero hits online.
|
||
- Fix path: check fragmentation and rebuild per [Vectorstore Fragmentation](https://github.com/onestardao/WFGY/blob/main/ProblemMap/patterns/pattern_vectorstore_fragmentation.md). Re-probe ΔS after rebuild.
|
||
|
||
- **Session flips between tabs or seeds**
|
||
- Symptom: same prompt, different claims by session.
|
||
- Fix path: pin the instruction header, move citations above free text, and follow [Memory Desync](https://github.com/onestardao/WFGY/blob/main/ProblemMap/patterns/pattern_memory_desync.md).
|

|
||
## Provider-specific knobs to audit
|
||
|
||
- **Model pinning**
|
||
- Pin an exact Gemini version where possible. Note the tokenizer budget before you add long system headers.
|
||
|
||
- **Safety configuration**
|
||
- Keep scope lawful and narrow in the header. If the task is research or code reading, state that explicitly and cite sources. This avoids silent rewrites.
|
||
|
||
- **Tool schema shape**
|
||
- Function name, arg names, and enum values must match your declared schema. Enforce with [Data Contracts](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md) and a post-validator.
|
||
|
||
- **Context budget**
|
||
- Large tool results or many citations can clip the tail. Trim with BBMC and move the schema above narrative text.
|
||
|
||
- **Region and project hygiene**
|
||
- Mismatched locations or stale projects can surface different defaults. Record the config in your trace header so λ checks are comparable.
|
||
|

|
||
|
||
## Minimal recipe
|
||
|
||
1) Put citation-first headers in the system prompt.
|
||
2) Lock snippet schema via [Retrieval Traceability](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-traceability.md) and [Data Contracts](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md).
|
||
3) Add BBCR bridge for safety-neutral framing.
|
||
4) Add BBPF alternate path for tool calls with explicit timeouts.
|
||
5) Verify acceptance using [Eval Semantic Stability](https://github.com/onestardao/WFGY/blob/main/ProblemMap/eval/eval_semantic_stability.md) and [RAG Precision/Recall](https://github.com/onestardao/WFGY/blob/main/ProblemMap/eval/eval_rag_precision_recall.md).

## Copy-paste prompt for your Vertex runbook
|
||
|
||
```
|
||
|
||
I am running on Google Vertex AI.
|
||
My failure:
|
||
|
||
* symptom: \[brief]
|
||
* traces: \[ΔS(question,retrieved)=..., ΔS(retrieved,anchor)=..., λ states, safety logs if any]
|
||
|
||
Tell me:
|
||
|
||
1. which layer is failing and why,
|
||
2. which exact WFGY fix page from this repo to open,
|
||
3. minimal steps to push ΔS ≤ 0.45 and keep λ convergent,
|
||
4. how to verify with a reproducible test.
|
||
|
||
Use BBMC/BBPF/BBCR/BBAM when relevant. If safety gating is suspected, propose a compliant BBCR rewrite and show the acceptance targets.
|
||
