WFGY Global Fix Map — main Emergency Room, 300+ structured fixes

WFGY Problem Map 1.0 — 16 reproducible failure modes

Think of this page as a desk within a ward.
If you need the full triage and all prescriptions, return to the Emergency Room lobby.

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

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

Retrieval drift → BBMC plus Data Contracts
Reasoning collapse in long refactors → BBCR bridge plus BBAM
Dead ends in multi-file edits → BBPF alternate paths

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, Data Contracts
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
Phantom references in generated tests High similarity to wrong helper files. Re-index, lock rerankers, add anchors to the correct module. Open: Embedding ≠ Semantic, Rerankers
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, Pre-Deploy Collapse
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, Pattern: SCU
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, Entropy Collapse

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, Retrieval Playbook
Plan length audit If entropy rises after 25 to 40 steps, split into subplans and join with a bridge. Open: Context Drift

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
Live instability Add live probes and a regression gate for ΔS and coverage before allowing code writes. Open: Live Monitoring for RAG, Debug Playbook

Copy-paste prompt for the Copilot Chat step

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.
