# Embeddings — Global Fix Map

A hub to stabilize embedding pipelines across stores and retrievers. Use this page to jump to per-tool guardrails and verify fixes with the same acceptance targets.

## Quick routes to per-page fixes
- Metric mismatch → [metric_mismatch.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/Embeddings/metric_mismatch.md)
- Normalization and scaling → [normalization_and_scaling.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/Embeddings/normalization_and_scaling.md)
- Tokenization and casing → [tokenization_and_casing.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/Embeddings/tokenization_and_casing.md)
- Chunking to embedding contract → [chunking_to_embedding_contract.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/Embeddings/chunking_to_embedding_contract.md)
- Vectorstore fragmentation → [vectorstore_fragmentation.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/Embeddings/vectorstore_fragmentation.md)
- Dimension mismatch and projection → [dimension_mismatch_and_projection.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/Embeddings/dimension_mismatch_and_projection.md)
- Update and index skew → [update_and_index_skew.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/Embeddings/update_and_index_skew.md)
- Hybrid retriever weights → [hybrid_retriever_weights.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/Embeddings/hybrid_retriever_weights.md)
- Duplication and near-duplicate collapse → [duplication_and_near_duplicate_collapse.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/Embeddings/duplication_and_near_duplicate_collapse.md)
- Poisoning and contamination → [poisoning_and_contamination.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/Embeddings/poisoning_and_contamination.md)

## When to use this folder
- High similarity yet wrong meaning.
- Citations do not line up with the retrieved section.
- Hybrid retrievers underperform a single retriever.
- Quality drops after re-embed or re-index.
- Index looks healthy but coverage stays low.

## Acceptance targets
- ΔS(question, retrieved) ≤ 0.45  
- Coverage of target section ≥ 0.70  
- λ remains convergent across 3 paraphrases and 2 seeds  
- E_resonance flat on long windows

## 60-second checklist
1) **Metrics and analyzer sanity** → [metric_mismatch.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/Embeddings/metric_mismatch.md)  
2) **Normalize and rescale vectors** → [normalization_and_scaling.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/Embeddings/normalization_and_scaling.md)  
3) **Unify tokenization and casing** → [tokenization_and_casing.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/Embeddings/tokenization_and_casing.md)  
4) **Lock the chunk→embed contract** → [chunking_to_embedding_contract.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/Embeddings/chunking_to_embedding_contract.md)  
5) **Defragment the store** → [vectorstore_fragmentation.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/Embeddings/vectorstore_fragmentation.md)  
6) **Fix dimension and projection paths** → [dimension_mismatch_and_projection.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/Embeddings/dimension_mismatch_and_projection.md)  
7) **Repair update and index skew** → [update_and_index_skew.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/Embeddings/update_and_index_skew.md)  
8) **Rebalance hybrid retrievers** → [hybrid_retriever_weights.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/Embeddings/hybrid_retriever_weights.md)  
9) **Collapse near-duplicates** → [duplication_and_near_duplicate_collapse.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/Embeddings/duplication_and_near_duplicate_collapse.md)  
10) **Audit poisoning and contamination** → [poisoning_and_contamination.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/Embeddings/poisoning_and_contamination.md)

## Map symptoms to structural fixes
- Wrong-meaning hits despite high similarity  
  → [embedding-vs-semantic.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/embedding-vs-semantic.md)
- Unverifiable citations or snippet drift  
  → [retrieval-traceability.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-traceability.md) · [data-contracts.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md)
- Results flip across runs or small paraphrases  
  → [context-drift.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/context-drift.md) · [entropy-collapse.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/entropy-collapse.md) · [rerankers.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/rerankers.md)
- Hallucination re-entry after correction  
  → [pattern_hallucination_reentry.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/patterns/pattern_hallucination_reentry.md)

## Verify the fix
- Log ΔS and λ for three paraphrases and two seeds.  
- Require coverage ≥ 0.70 and ΔS ≤ 0.45 before publish.  
- Keep a small gold set to re-test after any change to metric, tokenizer, or chunking.
