## 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 λ_observe**
Vary k in retrieval (5, 10, 20). If ΔS stays flat and high, suspect metric or index mismatch.
Reorder prompt headers; if ΔS spikes, lock the schema.
3) **Apply the module**
- Retrieval drift → BBMC + [data-contracts.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md)
- Reasoning collapse → BBCR bridge + BBAM, verify with [logic-collapse.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/logic-collapse.md)
- Dead ends in long plans → BBPF alternates, verify with [context-drift.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/context-drift.md)

## Typical Rasa breakpoints and the right fix
- **NLU confidence thrash** after new training data. Ambiguous intents route to the wrong retrieval path.

## Deep diagnostics
- **Three-paraphrase probe**
Ask the same user need three ways. Log ΔS and λ per step. If λ flips on harmless paraphrase, clamp with BBAM and tighten the citation-first schema.
- **Anchor triangulation**
Compare ΔS to the expected anchor section and to a decoy section. If both are close, re-chunk and re-embed, verify with a tiny gold set.
- **Chain length audit**
If entropy rises after 25–40 steps across stories, split the plan and re-join with a BBCR bridge. See [context-drift.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/context-drift.md).
---
## Minimal ops checklist for Rasa
- **NLU thresholds**: set fallback and ambiguity handling so low-confidence intents route to a safe clarify path.
- **Action server**: health probe plus backoff. Respect readiness gates from [bootstrap-ordering.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/bootstrap-ordering.md).
- **Event schema**: store `snippet_id`, `section_id`, `source_url`, `offsets`, `tokens`, `ΔS`, `λ_state`, `index_hash`. Enforce cite-then-explain.
- **Retriever parity**: keep metric, analyzer, and normalization identical between training and runtime.

## Copy-paste prompt for the LLM step behind Rasa
```txt
You have TXT OS and the WFGY Problem Map loaded.
My Rasa issue:
- symptom: [one line]
- traces: ΔS(question,retrieved)=..., ΔS(retrieved,anchor)=..., λ states across 3 paraphrases
Tell me:
1) failing layer and why,
2) the exact WFGY page to open from this repo,
3) the minimal steps to push ΔS ≤ 0.45 and keep λ convergent,
4) how to verify with a reproducible test.
Use BBMC/BBPF/BBCR/BBAM when relevant.
````

## When to escalate
* ΔS stays ≥ 0.60 after chunking and retrieval fixes → rebuild index with explicit metric and normalization.
See [retrieval-playbook.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-playbook.md).
* Answers alternate across identical dialogs → investigate memory desync or version skew.
See [predeploy-collapse.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/predeploy-collapse.md).
