# RAG + VectorDB — Global Fix Map A hub to stabilize retrieval pipelines at the **embedding ↔ vector store layer**. Use this folder when retrieval looks healthy on paper but citations, meaning, or stability collapse in practice. Every fix is structural, measurable, and store-agnostic. --- ## Quick routes to per-page guides * Metric mismatch → [metric_mismatch.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/RAG_VectorDB/metric_mismatch.md) * Normalization and scaling → [normalization_and_scaling.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/RAG_VectorDB/normalization_and_scaling.md) * Tokenization and casing → [tokenization_and_casing.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/RAG_VectorDB/tokenization_and_casing.md) * Chunking ↔ embedding contract → [chunking_to_embedding_contract.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/RAG_VectorDB/chunking_to_embedding_contract.md) * Vectorstore fragmentation → [vectorstore_fragmentation.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/RAG_VectorDB/vectorstore_fragmentation.md) * Dimension mismatch / projection errors → [dimension_mismatch_and_projection.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/RAG_VectorDB/dimension_mismatch_and_projection.md) * Update drift and index skew → [update_and_index_skew.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/RAG_VectorDB/update_and_index_skew.md) * Hybrid retriever weight errors → [hybrid_retriever_weights.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/RAG_VectorDB/hybrid_retriever_weights.md) * Duplication / near-duplicate collapse → [duplication_and_near_duplicate_collapse.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/RAG_VectorDB/duplication_and_near_duplicate_collapse.md) * Poisoning and contamination → [poisoning_and_contamination.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/RAG_VectorDB/poisoning_and_contamination.md) --- ## When to use this folder - High similarity but wrong meaning. - Correct facts exist in the corpus but never surface. - Citations inconsistent or missing across runs. - Token count spikes after deploy without corpus changes. - Index “looks fine” yet coverage stays flat. - Retrieval quality drifts after updates or merges. - Hybrid retrievers underperform single retrievers. - Duplicate or poisoned vectors destabilize the store. --- ## Acceptance targets (store-agnostic) - ΔS(question, retrieved) ≤ **0.45** - Coverage of target section ≥ **0.70** - λ stays convergent across **3 paraphrases** and **2 seeds** - E_resonance flat across long windows - Index skew ≤ **5%** after updates --- ## 60-second checklist 1. Lock **metric** and **analyzer** (cosine vs L2 vs dot). 2. Normalize embeddings (L2 norm, zero-mean scaling). 3. Align tokenization and casing with retriever. 4. Enforce chunking ↔ embedding contract. 5. Probe ΔS across paraphrases. If ≥0.60, escalate. 6. Audit duplication and contamination (hash and dedupe). 7. Monitor index skew after every update. 8. Verify hybrid retriever weights explicitly. --- ### 🔗 Quick-Start Downloads (60 sec) | Tool | Link | 3-Step Setup | |------|------|--------------| | **WFGY 1.0 PDF** | [Engine Paper](https://github.com/onestardao/WFGY/blob/main/I_am_not_lizardman/WFGY_All_Principles_Return_to_One_v1.0_PSBigBig_Public.pdf) | 1️⃣ Download · 2️⃣ Upload to your LLM · 3️⃣ Ask “Answer using WFGY + ” | | **TXT OS (plain-text OS)** | [TXTOS.txt](https://github.com/onestardao/WFGY/blob/main/OS/TXTOS.txt) | 1️⃣ Download · 2️⃣ Paste into any LLM chat · 3️⃣ Type “hello world” — OS boots instantly | --- ### 🧭 Explore More | Module | Description | Link | |-----------------------|----------------------------------------------------------|----------| | WFGY Core | WFGY 2.0 engine is live: full symbolic reasoning architecture and math stack | [View →](https://github.com/onestardao/WFGY/tree/main/core/README.md) | | Problem Map 1.0 | Initial 16-mode diagnostic and symbolic fix framework | [View →](https://github.com/onestardao/WFGY/tree/main/ProblemMap/README.md) | | Problem Map 2.0 | RAG-focused failure tree, modular fixes, and pipelines | [View →](https://github.com/onestardao/WFGY/blob/main/ProblemMap/rag-architecture-and-recovery.md) | | Semantic Clinic Index | Expanded failure catalog: prompt injection, memory bugs, logic drift | [View →](https://github.com/onestardao/WFGY/blob/main/ProblemMap/SemanticClinicIndex.md) | | Semantic Blueprint | Layer-based symbolic reasoning & semantic modulations | [View →](https://github.com/onestardao/WFGY/tree/main/SemanticBlueprint/README.md) | | Benchmark vs GPT-5 | Stress test GPT-5 with full WFGY reasoning suite | [View →](https://github.com/onestardao/WFGY/tree/main/benchmarks/benchmark-vs-gpt5/README.md) | | 🧙‍♂️ Starter Village 🏡 | New here?
