# 📒 Map-A · WFGY RAG Problem Map

This page is a reality check for Retrieval‑Augmented Generation.  
**Most RAG stacks break in repeatable ways**—hallucinating, drifting, or hiding their own logic.  
WFGY adds a semantic firewall on top of any retriever or LLM to turn those failures into deterministic fixes.

## ❓ Why do mainstream RAG pipelines fail?

| Root Cause | What Goes Wrong in Practice |
|------------|----------------------------|
| Vector similarity ≠ meaning | “Relevant” chunks that aren’t logically useful |
| No semantic memory | Model forgets context after a few turns |
| No knowledge boundary | LLM bluffs instead of admitting uncertainty |
| Hidden reasoning path | Impossible to debug why an answer appeared |

WFGY repairs each gap with ΔS tension checks, Tree memory, and BBCR/BBMC modules.

## 🔍 RAG Failures → WFGY Solutions

| Problem | WFGY Fix | Module(s) | Status | Notes |
|---------|----------|-----------|--------|-------|
| [Hallucination & Chunk Drift](./hallucination.md) | ΔS boundary + BBCR fallback | BBCR, BBMC | ✅ | Rejects low‑match chunks |
| [Interpretation Collapse](./retrieval-collapse.md) | Logic rebirth protocol | BBCR | ✅ | Recovers reasoning paths |
| [Long Chain Drift](./context-drift.md) | Tree checkpoints | BBMC, Tree | ✅ | Logs topic jumps |
| [Bluffing / Overconfidence](./bluffing.md) | Knowledge boundary guard | BBCR, λ_observe | ✅ | Halts on unknowns |
| [Semantic ≠ Embedding](./embedding-vs-semantic.md) | Residue minimization | BBMC, BBAM | ✅ | Verifies true meaning |
| [Debugging Black Box](./retrieval-traceability.md) | Traceable Tree audit | All modules | ✅ | Exposes logic path |
| Chunk ingestion pipeline | — | — | 🛠 | Manual paste for now |
| LangChain / LlamaIndex adapter | — | — | 🛠 | Planned integration |

---

## ✅ What you can do right now

- Paste any passage manually and test ΔS / λ_observe  
- Watch WFGY flag or correct hallucinated answers  
- Inspect the Tree to see **why** the engine decided anything

## 🧪 Quick Demo

> **PDF bot hallucinating?**  
> 1. Paste the suspect answer + source chunk into TXT OS.  
> 2. If ΔS spikes, WFGY pauses or reroutes via BBCR.  
> 3. Inspect the recorded Tree node—see the exact drift.

## 📋 FAQ (for busy engineers)

| Q | A |
|--|--|
| **Do I need a new retriever?** | No. WFGY sits after any retriever or even manual paste. |
| **Does this replace LangChain?** | No. It patches the logic gaps LangChain can’t cover. |
| **Is there a vector store built‑in?** | Not yet. Near‑term roadmap adds auto‑chunk mapping. |
| **Where do I ask deep tech questions?** | Use the **Discussions** tab—real traces welcome. |
