# GitHub Copilot Chat: Guardrails and Fix Patterns

A compact guide to stabilize Copilot Chat when it touches RAG, tool calls, terminals, and long multi-turn coding sessions. Use these checks to localize the failing layer, then jump to the exact WFGY fix page.

* Snippet and citation schema: [Data Contracts](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md)

## Core acceptance

* ΔS(question, retrieved) ≤ 0.45
* Coverage ≥ 0.70 to the target section
* λ remains convergent across three paraphrases and two seeds
* E\_resonance stays flat on long windows

---

## Fix in 60 seconds

1. **Measure ΔS**
   Compute ΔS(question, retrieved) and ΔS(retrieved, expected anchor).
   Stable < 0.40, transitional 0.40–0.60, risk ≥ 0.60.

2. **Probe with λ\_observe**
   Vary k in retrieval and reorder prompt headers. If ΔS stays flat and high, suspect metric or index mismatch. If λ flips, clamp with BBAM and lock the schema.

3. **Apply the module**

* Retrieval drift → BBMC + [Data Contracts](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md)
* Reasoning collapse → BBCR bridge + BBAM, then verify with [Logic Collapse](https://github.com/onestardao/WFGY/blob/main/ProblemMap/logic-collapse.md)
* Dead ends in long sessions → BBPF alternate paths

## Typical Copilot Chat breakpoints and the right fix

* **Inline chat cites the wrong paragraph** after a quick doc peek. Lock cite-then-explain and require snippet fields.
  Open: [Retrieval Traceability](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-traceability.md), [Data Contracts](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md)

* **High similarity but wrong meaning** when asking about a library API across repos. Rebuild with explicit metric and normalization, then rerank deterministically.
  Open: [Embedding ≠ Semantic](https://github.com/onestardao/WFGY/blob/main/ProblemMap/embedding-vs-semantic.md), [Rerankers](https://github.com/onestardao/WFGY/blob/main/ProblemMap/rerankers.md)

* **Two stage queries drift** when using HyDE plus code search. Lock the two queries and pin the reranker.
  Open: [Pattern: Query Parsing Split](https://github.com/onestardao/WFGY/blob/main/ProblemMap/patterns/pattern_query_parsing_split.md), [Rerankers](https://github.com/onestardao/WFGY/blob/main/ProblemMap/rerankers.md)

* **Terminal chat suggests unsafe commands** or edits that bypass guardrails. Enforce schema locks and allow-list tool arguments.
  Open: [Prompt Injection](https://github.com/onestardao/WFGY/blob/main/ProblemMap/prompt-injection.md), [Logic Collapse](https://github.com/onestardao/WFGY/blob/main/ProblemMap/logic-collapse.md)

* **Context flips across long refactors** where chat history mixes policy text with user turns. Move non-task policy to system and split the plan.
  Open: [Context Drift](https://github.com/onestardao/WFGY/blob/main/ProblemMap/context-drift.md), [Entropy Collapse](https://github.com/onestardao/WFGY/blob/main/ProblemMap/entropy-collapse.md)

* **Agent handoff stalls** between chat, code-lens, and terminal with partial memory writes. Split memory namespaces and lock by `mem_rev` and `mem_hash`.
  Open: [Multi-Agent Problems](https://github.com/onestardao/WFGY/blob/main/ProblemMap/Multi-Agent_Problems.md)

* **Fresh branch deploy fails on first call** when running evals from the IDE. Add boot fences for index, secrets, and version hash.
  Open: [Bootstrap Ordering](https://github.com/onestardao/WFGY/blob/main/ProblemMap/bootstrap-ordering.md), [Pre-deploy Collapse](https://github.com/onestardao/WFGY/blob/main/ProblemMap/predeploy-collapse.md)

## Deep diagnostics

* **Three-paraphrase probe**
  Ask the same question three ways. Log ΔS and λ. If λ flips on harmless paraphrase, clamp with BBAM and tighten snippet schema.

* **Anchor triangulation**
  Compare ΔS to the expected anchor section and to a decoy. If close for both, re-chunk and re-embed.
  See: [Embedding ≠ Semantic](https://github.com/onestardao/WFGY/blob/main/ProblemMap/embedding-vs-semantic.md)

* **Long chain audit**
  If entropy rises after 25–40 steps, split the plan, then re-join with a BBCR bridge.
  See: [Context Drift](https://github.com/onestardao/WFGY/blob/main/ProblemMap/context-drift.md), [Entropy Collapse](https://github.com/onestardao/WFGY/blob/main/ProblemMap/entropy-collapse.md)

## Copy-paste prompt for Copilot Chat

```txt
You have TXT OS and the WFGY Problem Map loaded.

My Copilot Chat issue:
- symptom: [one line]
- traces: ΔS(question,retrieved)=..., ΔS(retrieved,anchor)=..., λ states across 3 paraphrases

Tell me:
1) the failing layer and why,
2) the exact WFGY page to open,
3) minimal steps to push ΔS ≤ 0.45 and keep λ convergent,
4) a reproducible test to verify the fix.
When relevant, use BBMC, BBPF, BBCR, BBAM.
```
