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.

* 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 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 0.400.60, 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.
```
