Use this page when Copilot Chat is involved in code edits, refactors, tests, or RAG-style lookups over your repo. The goal is to localize the failure, then jump to the exact WFGY fix page with measurable acceptance.

## Core acceptance

* ΔS(question, retrieved) ≤ 0.45
* Coverage ≥ 0.70 for the target file or section
* λ remains convergent across three paraphrases and two seeds
* E\_resonance stays flat across multi-step edit plans

---

## Fix in 60 seconds

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

2. **Probe λ\_observe**
   Switch between chat-only context and file-selection context. If λ flips, lock the schema and force cite-then-explain with structured snippet fields.

3. **Apply the module**

* Retrieval drift → BBMC plus [Data Contracts](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md)
* Reasoning collapse in long refactors → BBCR bridge plus BBAM
* Dead ends in multi-file edits → BBPF alternate paths

4. **Verify**
   Coverage ≥ 0.70 on three paraphrases. λ convergent on two seeds. Plan produces the same diff twice.

---

## Typical Copilot Chat breakpoints and the right fix

* **Editor selection vs chat context mismatch**
  The model cites lines not in the selected file or mixes files. Enforce a snippet schema: `file_path`, `commit_sha`, `line_start`, `line_end`, `snippet_id`.
  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)

* **Non-deterministic code edits from “fix” commands**
  Same prompt gives different diffs. Require a dry-run plan then a deterministic patch step; clamp variance with BBAM.
  Open: [Logic Collapse](https://github.com/onestardao/WFGY/blob/main/ProblemMap/logic-collapse.md)

* **Phantom references in generated tests**
  High similarity to wrong helper files. Re-index, lock rerankers, add anchors to the correct module.
  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)

* **Repo or symbol index not warmed**
  First runs fail or time out. Add a warm-up fence for index and secrets before allowing edit plans.
  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)

* **Prompt injection via comments or README**
  Model executes unsafe terminal steps copied from docs. Lock tool protocols and force SCU to separate sources.
  Open: [Prompt Injection](https://github.com/onestardao/WFGY/blob/main/ProblemMap/prompt-injection.md), [Pattern: SCU](https://github.com/onestardao/WFGY/blob/main/ProblemMap/patterns/pattern_symbolic_constraint_unlock.md)

* **Long chat drift across edits**
  Plans degrade after many steps and reintroduce removed code. Split the plan and re-join with a BBCR bridge.
  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)

---

## Minimal schema you should capture

`{ file_path, commit_sha, snippet_id, line_start, line_end, tokens, ΔS, λ_state }`
Store per step. Require cite-then-explain. Forbid cross-file reuse without a new citation entry.

---

## Deep diagnostics

* **Three-paraphrase probe**
  Ask the same refactor three ways. If λ flips with harmless header reorder, lock the prompt headers and apply BBAM.

* **Anchor triangulation**
  Compare ΔS to the intended file and a decoy file. If ΔS is close for both, re-chunk and adjust retrieval metric.
  Open: [Embedding ≠ Semantic](https://github.com/onestardao/WFGY/blob/main/ProblemMap/embedding-vs-semantic.md), [Retrieval Playbook](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-playbook.md)

* **Plan length audit**
  If entropy rises after 25 to 40 steps, split into subplans and join with a bridge.
  Open: [Context Drift](https://github.com/onestardao/WFGY/blob/main/ProblemMap/context-drift.md)

---

## Escalate and structural fixes

* **Index or metric mismatch persists**
  Rebuild symbols and embeddings with explicit analyzers, then verify with a small gold set and reranker.
  Open: [Rerankers](https://github.com/onestardao/WFGY/blob/main/ProblemMap/rerankers.md)

* **Live instability**
  Add live probes and a regression gate for ΔS and coverage before allowing code writes.
  Open: [Live Monitoring for RAG](https://github.com/onestardao/WFGY/blob/main/ProblemMap/ops/live_monitoring_rag.md), [Debug Playbook](https://github.com/onestardao/WFGY/blob/main/ProblemMap/ops/debug_playbook.md)

## Copy-paste prompt for the Copilot Chat step

```txt
You have TXTOS and the WFGY Problem Map loaded.

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

Do:
1) identify the failing layer,
2) link the exact WFGY page to open,
3) give the minimal steps to push ΔS ≤ 0.45 and keep λ convergent,
4) return a 2-stage plan: dry-run diff plan, then deterministic patch,
5) output:
{ "citations":[...], "plan":[...], "λ_state":"→|←|<>|×", "ΔS":0.xx, "next_fix":"..." }
Use BBMC, BBPF, BBCR, BBAM when relevant. Keep it auditable and short.
```
