A hub to stabilize IDE copilots and code-AI assistants without changing infra.
Every tool has its own guardrail page. Each target here has simple explanations so even new users can follow.

## When to use this folder
- **Unstable answers**: IDE chat gives different results on the same question.
- **Loops or stalls**: Tool calls stop halfway or keep retrying after edits.
- **Broken JSON**: You expect JSON output but get plain text.
- **Wrong citations**: Answer looks correct but cites the wrong part of code/docs.
- **Drift in long refactors**: After 20–40 reasoning steps, output drifts off track.
---
## Acceptance targets (with plain meaning)
- **ΔS (semantic drift score) ≤ 0.45**
*How far the answer drifts from your question. Lower is better.*
- **Coverage ≥ 0.70**
*How much of the correct section is included in the answer.*
- **λ (stability factor) stays convergent**
*If you re-ask with small rephrasing, results stay consistent.*
- **E_resonance flat**
*On long sessions, answers do not wander or change meaning.*

## Map symptoms → structural fixes
| Symptom | Why it happens | Fix page |
|---------|----------------|----------|
| **Wrong-meaning hits despite high similarity** | Embedding captures surface form but not real meaning. | [embedding-vs-semantic.md](../../embedding-vs-semantic.md) |
| **Citations do not line up** | Traceability layer too loose, snippet schema missing. | [retrieval-traceability.md](../../retrieval-traceability.md) · [data-contracts.md](../../data-contracts.md) |
| **Answers flip between sessions/tabs** | Context not anchored, entropy builds up. | [context-drift.md](../../context-drift.md) · [entropy-collapse.md](../../entropy-collapse.md) |
| **JSON mode breaks, prose returned** | Model leaves structured mode or prompt injection occurs. | [logic-collapse.md](../../logic-collapse.md) · [prompt-injection.md](../../prompt-injection.md) |
| **Multi-agent or tool handoff stalls** | Agents lose roles, no schema lock in exchange. | [Multi-Agent_Problems.md](../../Multi-Agent_Problems.md) · [role-drift.md](../../multi-agent-chaos/role-drift.md) |
| **Hybrid retrievers worse than single** | Query parsing split or reranker mis-weighted. | [pattern_query_parsing_split.md](../../patterns/pattern_query_parsing_split.md) · [rerankers.md](../../rerankers.md) |

## Fix in 60 seconds
1. **Measure ΔS**
If drift ≥ 0.60, you have unstable retrieval.
2. **Probe λ**
Re-ask with 2–3 paraphrases. If answers flip, lock schema.
3. **Apply guardrails**
- Retrieval drift → BBMC + [data-contracts.md](../../data-contracts.md)
- Reasoning collapse → BBCR bridge + BBAM + [logic-collapse.md](../../logic-collapse.md)
- Dead ends → BBPF alternate paths
4. **Verify**
Coverage ≥ 0.70, λ stable, ΔS ≤ 0.45.

## Copy-paste prompt for IDE chat
```
I loaded TXT OS and the WFGY Problem Map.
My code-AI issue:
* symptom: \[one line]
* traces: ΔS(question,retrieved)=..., ΔS(retrieved,anchor)=..., λ states
Tell me:
1. failing layer and why,
2. the exact WFGY page to open,
3. minimal steps to push ΔS ≤ 0.45 and keep λ convergent,
4. how to verify with a reproducible test.
```

## FAQ
**Q1. What is ΔS?**
It is the “semantic drift score”. Think of it as how far the answer strays from the original question. Lower numbers = more accurate.
**Q2. What is λ (lambda)?**
A stability check. If you slightly rephrase the same question, λ shows if the model’s answers converge or scatter.
**Q3. What does E_resonance mean?**
It is a long-run stability check. If E_resonance is flat, your assistant stays consistent even after many steps.
**Q4. Do I need to understand BBMC/BBPF/BBCR/BBAM?**
No. These are internal WFGY modules. Just know:
- BBMC = stabilizes retrieval,
- BBPF = creates fallback paths,
- BBCR = bridges reasoning collapse,
- BBAM = variance clamp for stability.
**Q5. I only use one IDE plugin. Why should I care?**
Because the same drift and instability happens across **all** copilots. Fixes here apply no matter which tool you use.
**Q6. How do I test quickly?**
Ask the same question 3 times with small wording changes. If answers flip, you need λ guardrails.
