Use this page when Tabnine autocompletes the wrong API, mixes symbols across packages, or flips outputs between local and cloud contexts. The fixes route back to WFGY pages with measurable targets so you can verify without changing infra.

## Core acceptance

* ΔS(question, retrieved) ≤ 0.45
* Coverage ≥ 0.70 to the target function or spec anchor
* λ remains convergent across three paraphrases and two seeds
* E\_resonance stays flat across long edit plans

---

## 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 λ\_observe**
   Toggle local versus cloud context and vary k. Pin reranker. If ΔS stays flat and high, suspect metric or index mismatch. If λ flips on harmless header reorder, lock schema and clamp with BBAM.

3. **Apply the module**

* Retrieval drift in code or docs → BBMC plus [Data Contracts](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md)
* Reasoning collapse in long refactors → BBCR bridge plus BBAM, verify with [Logic Collapse](https://github.com/onestardao/WFGY/blob/main/ProblemMap/logic-collapse.md)
* Dead ends in edit plans or test generation → BBPF alternate paths
* Hybrid search worse than single → Pattern [Query Parsing Split](https://github.com/onestardao/WFGY/blob/main/ProblemMap/patterns/pattern_query_parsing_split.md) and [Rerankers](https://github.com/onestardao/WFGY/blob/main/ProblemMap/rerankers.md)

4. **Verify**
   Coverage ≥ 0.70 on three paraphrases. λ convergent on two seeds. Same diff twice.

## Typical Tabnine breakpoints and the right fix

* **Local vs cloud index skew**
  Suggestions differ after a reboot or network switch. Warm up the selected index, fence first run, verify analyzer settings.
  Open: [Bootstrap Ordering](https://github.com/onestardao/WFGY/blob/main/ProblemMap/bootstrap-ordering.md)

* **Wrong symbol in a monorepo**
  Near neighbor symbols from sibling packages win due to similarity. Lock anchors to `repo@commit` and `subdir`, require cite then explain.
  Open: [Retrieval Traceability](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-traceability.md), [Embedding ≠ Semantic](https://github.com/onestardao/WFGY/blob/main/ProblemMap/embedding-vs-semantic.md)

* **Generated tests reference phantom helpers**
  Enforce file spans and commit SHA before test generation.
  Open: [Data Contracts](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md)

* **Plan loops during multi file edits**
  Split plan and re join with a bridge step. Clamp variance in the patch step.
  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)

* **Similarity high but meaning wrong**
  Metric or normalization mismatch or fragmented store. Rebuild with explicit metric and fix fragmentation.
  Open: [Embedding ≠ Semantic](https://github.com/onestardao/WFGY/blob/main/ProblemMap/embedding-vs-semantic.md), [Vectorstore Fragmentation](https://github.com/onestardao/WFGY/blob/main/ProblemMap/patterns/pattern_vectorstore_fragmentation.md)

* **Unsafe shell or tool suggestions copied from docs**
  Lock tool allow lists, require SCU separation for untrusted text.
  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)

* **Org policy or model switch changes outputs silently**
  Make refusal paths explicit. Echo the active policy and model in the plan.
  Open: [Multi-Agent Problems](https://github.com/onestardao/WFGY/blob/main/ProblemMap/Multi-Agent_Problems.md), [Data Contracts](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md)

## IDE checklist for Tabnine

* Warm up the selected context source and verify `INDEX_HASH`, credentials, and policy mode.
* Use one retrieval metric per run. Do not mix analyzers while fixing one bug.
* Prompts carry anchors: `repo@commit`, `file_path`, `symbol`, `line_start`, `line_end`, `snippet_id`.
* Log per step: ΔS, λ state, coverage. Alert when ΔS ≥ 0.60 or λ diverges.
* Regression gate requires tests pass, coverage ≥ 0.70, ΔS ≤ 0.45, identical diff twice.

---

## Minimal schema you should capture

`{ repo, commit_sha, file_path, symbol, line_start, line_end, snippet_id, tokens, ΔS, λ_state }`
Require cite then explain. Forbid cross file reuse without a new citation.

---

## Deep diagnostics

* **Three paraphrase probe**
  Ask the same change three ways. If λ flips, clamp with BBAM and lock headers.

* **Anchor triangulation**
  Compare ΔS for target vs decoy file or sibling package. If close, re chunk and normalize embeddings.
  See: [Retrieval Playbook](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-playbook.md), [Embedding ≠ Semantic](https://github.com/onestardao/WFGY/blob/main/ProblemMap/embedding-vs-semantic.md)

* **Plan length audit**
  If entropy rises after 25 to 40 steps, split the plan and re join with a BBCR bridge.
  See: [Entropy Collapse](https://github.com/onestardao/WFGY/blob/main/ProblemMap/entropy-collapse.md)

* **Live instability**
  Add probes and backoff guards in IDE tasks.
  See: [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 Tabnine chat

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

My Tabnine issue:
- symptom: [one line]
- anchors: repo={name}, commit={sha}, file={path}, lines={a..b}
- traces: ΔS(question,retrieved)=..., ΔS(retrieved,anchor)=..., λ 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.
Use BBMC, BBPF, BBCR, BBAM when relevant. Keep it auditable and short.
```
