## 0) 🎯 Why this guide exists

When RAG breaks, it’s rarely one bug. It’s stacked illusions across OCR → chunking → embedding → retrieval → prompt → reasoning.  
This guide helps you:

1) **Identify** the failure family fast  
2) **Apply** the minimal structural fix (not prompt band-aids)  
3) **Verify** with objective signals: **ΔS** (semantic stress), **λ_observe** (layered states), **E_resonance** (coherence)

Then jump deeper via **Problem Map 2.0** and **Patterns**.

**Extended patterns (very common in the wild):**
- Hybrid HyDE+BM25 **gets worse than single** → [`patterns/pattern_query_parsing_split.md`](./patterns/pattern_query_parsing_split.md)  
- Two sources **merge into one** (who-said-what mixes) → [`patterns/pattern_symbolic_constraint_unlock.md`](./patterns/pattern_symbolic_constraint_unlock.md)  
- You correct it, **bad fact returns later** → [`patterns/pattern_hallucination_reentry.md`](./patterns/pattern_hallucination_reentry.md)  
- State flips across **tabs/sessions** → [`patterns/pattern_memory_desync.md`](./patterns/pattern_memory_desync.md)  
- Some facts **won’t retrieve** though indexed → [`patterns/pattern_vectorstore_fragmentation.md`](./patterns/pattern_vectorstore_fragmentation.md)  
- RAG **boots** but tools fire too early → [`patterns/pattern_bootstrap_deadlock.md`](./patterns/pattern_bootstrap_deadlock.md)

## 2) 🧠 Core concepts in <5 minutes

### 2.1 What is RAG?

```

raw docs → ocr/parsing → chunking → embeddings → vector store
→ retriever → prompt assembly → LLM reasoning/tools

```

- **Perception drift** upstream hides **logic drift** downstream. Fix structure, not style.

### 2.2 Embedding scores vs. meaning  
Cosine proximity ≠ human semantics. WFGY’s **ΔS = 1 − cos(I, G)** uses grounded anchors to catch real meaning gaps.

### 2.3 Layered observability (λ_observe)  
States: **→** convergent · **←** divergent · **<>** recursive · **×** chaotic.  
If upstream is stable but downstream flips, the boundary between them is failing.

### 2.4 WFGY repair operators (cheat-sheet)

| Operator | What it does (1-liner) |
|---|---|
| **BBMC** | Minimize semantic residue to re-align with anchors |
| **BBPF** | Explore safe alternate paths; avoid dead-end chains |
| **BBCR** | Detect collapse; insert **bridge** node; rebuild reasoning |
| **BBAM** | Modulate attention variance; prevent entropy melt |

## 3) 🛠️ Run your first fix (3 minutes)

1) **Download** the assets below, or jump to **[Getting Started](./getting-started.md)** for a runnable pipeline.  
2) Paste **TXT OS** into your model chat.  
3) Ask:

```

I’ve loaded TXT OS. Diagnose my RAG:

* symptom: \[describe]
* trace: \[question, retrieved snippet(s), answer]
  Using WFGY, tell me:

1. failing layer & why (ΔS/λ),
2. the Problem Map page to open,
3. minimal steps to push ΔS ≤ 0.45 and keep λ convergent,
4. how to verify with a reproducible test.

```

**Triage thresholds (keep these handy):**
- **ΔS:** `<0.40` stable · `0.40–0.60` transitional (record if λ ∈ {←, <>}) · `≥0.60` high-risk (act)  
- **Acceptance:** ΔS(question, context) ≤ **0.45**, λ **convergent**, E_resonance **flat**

## 4) 🗂️ Problem categories (cheat-labels)

| Category | Typical stage | Open first |
|---|---|---|
| **Retrieval** | Vector DB, search, chunking | [`hallucination.md`](./hallucination.md) · [`embedding-vs-semantic.md`](./embedding-vs-semantic.md) |
| **Reasoning** | Mid-chain logic | [`retrieval-collapse.md`](./retrieval-collapse.md) · [`logic-collapse.md`](./logic-collapse.md) |
| **Patterns** | High-frequency edge cases | [`patterns/README.md`](./patterns/README.md) |
| **Eval** | Measure & guard regressions | [`eval/README.md`](./eval/README.md) |
| **Ops** | Boot order, runbooks | [`ops/README.md`](./ops/README.md) |

---

## 5) ✅ Verify the repair (don’t skip)

- **Retrieval sanity:** ≥ 70% token overlap with target section; ΔS(question, context) ≤ 0.45 → see [`eval/eval_rag_precision_recall.md`](./eval/eval_rag_precision_recall.md)  
- **Reasoning stability:** λ stays convergent on 3 paraphrases; E_resonance flat → see [`eval/eval_semantic_stability.md`](./eval/eval_semantic_stability.md)  
- **Latency vs accuracy:** chart ΔS vs p95 latency → see [`eval/eval_latency_vs_accuracy.md`](./eval/eval_latency_vs_accuracy.md)

## 6) 🙋 FAQ (super short)

| Question | Answer |
|---|---|
| Do I need all operators? | No. Use the one named on the matching page. |
| Does WFGY replace LangChain/LlamaIndex? | No. It sits **above** them as a reasoning firewall. |
| Will this work on small models? | Yes; #11/#12 are easier on GPT-4-class or strong local models. |
| Where are runnable examples? | Start here: [`examples/README.md`](./examples/README.md) and [`example_01_basic_fix.md`](./examples/example_01_basic_fix.md). |
