# 🏥 Semantic Clinic Index
**A complete triage hub for AI failures — beyond the core 16 — powered by WFGY.**
Use this page when you don’t yet know *which thing is breaking*. Start from symptoms, jump to a failure family, then open the exact fix page. All fixes are driven by WFGY instruments: `ΔS` (semantic stress), `λ_observe` (layered observability), and `E_resonance` (coherence control).
> If this page saves you time, a ⭐ helps others find it.

## How to use this page
1. **Identify the symptom** in the table below.
2. **Open the family** (Prompting / Retrieval / Reasoning / Memory / Agents / Infra / Eval).
3. **Follow the fix page**, then verify with **ΔS ≤ 0.45** and **convergent λ**.
Prefer a pipeline-first view (OCR → chunk → embed → store → retrieve → prompt → LLM)?
Read **[`RAG Architecture & Recovery`](./rag-architecture-and-recovery.md)**.

## Quick triage by symptom
| Symptom you see | Likely family | Open this |
|---|---|---|
| Answers cite wrong snippet / mismatch with ground truth | Retrieval → RAG | [`hallucination.md`](./hallucination.md) |
| Chunks look right but reasoning is wrong | Reasoning | [`retrieval-collapse.md`](./retrieval-collapse.md) |
| High similarity, wrong meaning | Retrieval / Embeddings | [`embedding-vs-semantic.md`](./embedding-vs-semantic.md) |
| Model can’t explain *why* (no trace) | Observability | [`retrieval-traceability.md`](./retrieval-traceability.md) |
| Output degrades over 100k-token dialogs | Memory / Long-context | [`entropy-collapse.md`](./entropy-collapse.md) · [`context-drift.md`](./context-drift.md) |
| OCR PDFs **look** correct yet answers drift | Data / OCR | [`ocr-parsing-checklist.md`](./ocr-parsing-checklist.md) |
| Hybrid (HyDE + BM25) gets worse than single retriever | Retrieval / Querying | [`patterns/pattern_query_parsing_split.md`](./patterns/pattern_query_parsing_split.md) |
| Corrections don’t stick; model re-asserts old claim | Reasoning / Prompting | [`patterns/pattern_hallucination_reentry.md`](./patterns/pattern_hallucination_reentry.md) |
| “Who said what” merges across sources | Prompting / Constraints | [`patterns/pattern_symbolic_constraint_unlock.md`](./patterns/pattern_symbolic_constraint_unlock.md) |
| Some facts can’t be retrieved though indexed | Retrieval / Index | [`patterns/pattern_vectorstore_fragmentation.md`](./patterns/pattern_vectorstore_fragmentation.md) |
| Answers flip between sessions / tabs | Memory / State | [`patterns/pattern_memory_desync.md`](./patterns/pattern_memory_desync.md) |
| Multi-agent tools fight each other | Agents | [`Multi-Agent_Problems.md`](./Multi-Agent_Problems.md) |
| First prod call crashes after deploy | Infra / Boot | [`predeploy-collapse.md`](./predeploy-collapse.md) |
| Tools fire before data is ready (RAG boot fence) | Infra / Boot | [`patterns/pattern_bootstrap_deadlock.md`](./patterns/pattern_bootstrap_deadlock.md) |

## Families & maps (with exact fixes)
### A) Prompting & Safety
Guard against injections, role drift, and schema leakage.
- **Citation-first, schema-locked prompting** — [`retrieval-traceability.md`](./retrieval-traceability.md)
- **Overconfidence / Bluffing Controls** — [`bluffing.md`](./bluffing.md)
- **Symbolic Constraint Unlock (SCU) / source mixing** — [`patterns/pattern_symbolic_constraint_unlock.md`](./patterns/pattern_symbolic_constraint_unlock.md)
**Verification**: ΔS(question, context) ≤ 0.45; λ remains convergent across paraphrases; constraint probes do not flip λ.
---
### B) Retrieval, Data & Vector Stores
Make the index correct, measured, and explainable.
- **Hallucination & Chunk Drift** — [`hallucination.md`](./hallucination.md)
- **Interpretation vs Retrieval Collapse** — [`retrieval-collapse.md`](./retrieval-collapse.md)
- **Embedding ≠ Semantic Meaning** — [`embedding-vs-semantic.md`](./embedding-vs-semantic.md)
- **Traceability (why this snippet?)** — [`retrieval-traceability.md`](./retrieval-traceability.md)
- **Vectorstore Fragmentation** — [`patterns/pattern_vectorstore_fragmentation.md`](./patterns/pattern_vectorstore_fragmentation.md)
- **Query Parsing Split (HyDE/BM25)** — [`patterns/pattern_query_parsing_split.md`](./patterns/pattern_query_parsing_split.md)
- **Semantic Chunking Checklist** — [`chunking-checklist.md`](./chunking-checklist.md)
- **OCR / Parsing Quality Gate** — [`ocr-parsing-checklist.md`](./ocr-parsing-checklist.md)
**Verification**: coverage ≥ 0.70 to target section; ΔS(question, retrieved) ≤ 0.45; flat-high ΔS vs k ⇒ index/metric mismatch.
---
### C) Reasoning & Logic Control
Detect and repair logic collapse, dead ends, and abstraction failures.
- **Logic Collapse & Recovery** — [`logic-collapse.md`](./logic-collapse.md)
- **Long Reasoning Chains** — [`context-drift.md`](./context-drift.md)
- **Symbolic Collapse** — [`symbolic-collapse.md`](./symbolic-collapse.md)
- **Philosophical Recursion** — [`philosophical-recursion.md`](./philosophical-recursion.md)
- **Hallucination Re-entry** — [`patterns/pattern_hallucination_reentry.md`](./patterns/pattern_hallucination_reentry.md)
**Verification**: fix point when λ stays convergent after BBCR (bridge) + BBAM (variance clamp).
---
### D) Memory & Long-Context
Keep threads coherent across sessions and very long windows.
- **Memory Breaks Across Sessions** — [`memory-coherence.md`](./memory-coherence.md)
- **Entropy Collapse** — [`entropy-collapse.md`](./entropy-collapse.md)
- **Memory Desync** — [`patterns/pattern_memory_desync.md`](./patterns/pattern_memory_desync.md)
**Verification**: E_resonance flat; ΔS stable at window joins.
---
### E) Multi-Agent & Orchestration
Coordinate tools, roles, and shared memory without conflict.
- **Multi-Agent Chaos (overview map)** — [`Multi-Agent_Problems.md`](./Multi-Agent_Problems.md)
- **Role Drift (Deep Dive)** — [`multi-agent-chaos/role-drift.md`](./multi-agent-chaos/role-drift.md)
- **Cross-Agent Memory Overwrite (Deep Dive)** — [`multi-agent-chaos/memory-overwrite.md`](./multi-agent-chaos/memory-overwrite.md)
**Verification**: when agents couple, ΔS does not spike; arbitration logs traceable.
---
### F) Infra / Deploy
Boot in a known-good order, every time.
- **Bootstrap Ordering** — [`bootstrap-ordering.md`](./bootstrap-ordering.md)
- **Deployment Deadlock** — [`deployment-deadlock.md`](./deployment-deadlock.md)
- **Pre-Deploy Collapse** — [`predeploy-collapse.md`](./predeploy-collapse.md)
- **Live Monitoring & Debug Playbook** — [`ops/live_monitoring_rag.md`](./ops/live_monitoring_rag.md) · [`ops/debug_playbook.md`](./ops/debug_playbook.md)
**Verification**: deterministic warm-up; idempotent index builds; version/secret checks pass.
---
### G) Evaluation & Guardrails
Detect “double hallucination” and prevent regression.
- **RAG Precision/Recall** — [`eval/eval_rag_precision_recall.md`](./eval/eval_rag_precision_recall.md)
- **Latency vs Accuracy** — [`eval/eval_latency_vs_accuracy.md`](./eval/eval_latency_vs_accuracy.md)
- **Cross-Agent Consistency** — [`eval/eval_cross_agent_consistency.md`](./eval/eval_cross_agent_consistency.md)
- **Semantic Stability** — [`eval/eval_semantic_stability.md`](./eval/eval_semantic_stability.md)
**Acceptance**: retrieve QA coverage ≥ 0.70 and ΔS ≤ 0.45; λ convergent; repeatability across seeds.

## Ask the AI to fix your AI (safe prompt)
```txt
Read the WFGY TXT OS and Problem Map docs. Extract ΔS, λ_observe, E_resonance and the modules (BBMC, BBPF, BBCR, BBAM).
Given my failure:
- symptom: [describe]
- traces: [ΔS probes, λ states if any]
Tell me:
1) which layer/family is failing and why,
2) which fix page to open,
3) minimal steps to push ΔS ≤ 0.45 and keep λ convergent,
4) how to verify the fix.
