## Fix in 60 seconds
1) **Measure ΔS**
Compute ΔS(question, retrieved) and ΔS(retrieved, expected anchor).
Targets: stable < 0.40, transitional 0.40–0.60, risk ≥ 0.60.
2) **Probe with λ_observe**
Sweep k in {5, 10, 20}. Flat high curve means metric or index mismatch.
Reorder prompt headers. If ΔS spikes, lock schema with Data Contracts.
3) **Apply the module**
Retrieval drift → **BBMC** + **Data Contracts**.
Reasoning collapse → **BBCR** bridge + **BBAM** variance clamp.
Dead ends in long runs → **BBPF** alternate path.
4) **Verify acceptance**
Coverage ≥ 0.70 to the target section.
ΔS ≤ 0.45 on three paraphrases.
λ remains convergent. Logs reproducible.
## Pinecone breakpoints and the right repair
**1) Namespace mismatch**
- Symptom: zero results for known docs, or recall only for a subset.
- Fix: audit write and read namespaces. Stamp `ns`, `doc_sha`, and `mem_rev` in metadata, then re-test with [Retrieval Traceability](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-traceability.md).
**2) Metric choice vs encoder**
- Symptom: high similarity yet wrong meaning.
- Fix: align cosine vs dot vs L2 with the embedding family. If you switch, rebuild the index. See [Embedding ≠ Semantic](https://github.com/onestardao/WFGY/blob/main/ProblemMap/embedding-vs-semantic.md) and add [Rerankers](https://github.com/onestardao/WFGY/blob/main/ProblemMap/rerankers.md) for ordering.
**3) Dimension drift after model swap**
- Symptom: insert errors in client or silent truncation, chaotic top-k for new data only.
- Fix: lock encoder version and vector dim in a data contract, then re-ingest. See [Data Contracts](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md).
**4) Upsert hygiene**
- Symptom: duplicates, stale copies, or toggling answers.
- Fix: deterministic IDs, `doc_sha` metadata, and idempotent loaders. Validate with a golden query set. See [Retrieval Traceability](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-traceability.md).
**5) Hybrid sparse+dense weighting**
- Symptom: hybrid returns worse results than either retriever alone.
- Fix: normalize both branches, fuse after retrieval, and add a cross-encoder reranker. See [Query Parsing Split](https://github.com/onestardao/WFGY/blob/main/ProblemMap/patterns/pattern_query_parsing_split.md) and [Rerankers](https://github.com/onestardao/WFGY/blob/main/ProblemMap/rerankers.md).
**6) Filter semantics and type drift**
- Symptom: filters match in isolation but return empty under load or across namespaces.
- Fix: lock a minimal metadata schema and validate types on ingest. See [Data Contracts](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md).
**7) Fragmentation across indexes or namespaces**
- Symptom: global recall looks fine but per-scope top-k is weak.
- Fix: consolidate or route by a stable key, rebuild a single authoritative index, then rerank. See [Vectorstore Fragmentation](https://github.com/onestardao/WFGY/blob/main/ProblemMap/patterns/pattern_vectorstore_fragmentation.md).
**8) Cold start after deploy**
- Symptom: first call fails or returns thin results, later calls improve.
- Fix: add a semantic boot fence and idempotent warm-up. See [Bootstrap Ordering](https://github.com/onestardao/WFGY/blob/main/ProblemMap/bootstrap-ordering.md) and [Pre-deploy Collapse](https://github.com/onestardao/WFGY/blob/main/ProblemMap/predeploy-collapse.md).
## Observability probes
- **k-sweep curve**: 5, 10, 20. Flat high ΔS points to metric or routing faults.
- **Anchor control**: compare against a golden set. If only one namespace fails, route or rebuild.
- **Hybrid toggle**: vector only vs hybrid. If hybrid is worse, fix weights and query split.
- **Reranker audit**: strong reranker should reduce ΔS while recall improves. If not, rebuild.
## Escalate when
- ΔS stays ≥ 0.60 on golden questions after metric and namespace fixes.
- Coverage cannot reach 0.70 even with reranker and clean anchors.
- Writes appear in logs but not in results within the expected window.

## Copy-paste prompt for your AI
```
I uploaded TXT OS and the WFGY Problem Map files.
Target system: Pinecone.
* symptom: \[brief]
* traces: ΔS(question,retrieved)=..., ΔS(retrieved,anchor)=..., λ states
* index: \[metric, dim, pods/serverless mode, namespaces, filters, hybrid weights]
* encoder: \[model, normalization, version]
* ingest: \[ids, doc\_sha, upsert policy, loaders]
Tell me:
1. which layer is failing and why,
2. which exact fix page to open from this repo,
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.
