# IBM watsonx Assistant: Guardrails and Fix Patterns
Use this page to stabilize **watsonx Assistant** projects that combine Actions, Search, webhooks, function calls, and LLM answers. The checks map to WFGY Problem Map pages with measurable targets, so you can verify without changing infra.

## Core acceptance
* ΔS(question, retrieved) ≤ 0.45
* Coverage to the target section ≥ 0.70
* λ remains convergent across three paraphrases and two seeds
* E\_resonance flat across long dialog windows
---
## Fix in 60 seconds
1. **Measure ΔS**
Compute ΔS(question, retrieved) and ΔS(retrieved, expected anchor).
Thresholds: stable < 0.40, transitional 0.400.60, risk 0.60.
2. **Probe λ\_observe**
Vary k in retrieval and reorder prompt headers.
If λ flips on harmless paraphrases, lock the schema and clamp variance with BBAM.
3. **Apply module**
* Retrieval drift → BBMC + [data-contracts.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md)
* Reasoning collapse in long flows → BBCR bridge + BBAM, verify with [context-drift.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/context-drift.md)
* Dead ends in multi step plans → BBPF alternate paths
4. **Verify**
Three paraphrases hit coverage ≥ 0.70 and ΔS ≤ 0.45.
λ stays convergent across two seeds.

## CX surface guardrails
**Actions**
Keep policy text in a dedicated system context. Do not mix policy with user turns. Enforce cite-then-explain for any Action that answers. Lock input and output fields with contracts. See [data-contracts.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md).
**Search**
Require the snippet schema: `snippet_id`, `section_id`, `source_url`, `offsets`, `tokens`. If ΔS stays ≥ 0.60 after reranking, rebuild chunks and verify with a small gold set. See [retrieval-traceability.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-traceability.md), [chunking-checklist.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/chunking-checklist.md).
**Webhooks**
Echo the tool schema at every turn. Log `ΔS`, `λ_state`, `INDEX_HASH`, `snippet_id`. If flip states appear, clamp with BBAM. See [prompt-injection.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/prompt-injection.md).
**Live ops**
Fence first call after deploy and add backoff guards. See [ops/live\_monitoring\_rag.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/ops/live_monitoring_rag.md), [ops/debug\_playbook.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/ops/debug_playbook.md).
---
## Minimal webhook recipe
1. **Warm-up fence**
Check `VECTOR_READY`, `INDEX_HASH`, secrets. If not ready, short-circuit with a delay and capped retries.
See [bootstrap-ordering.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/bootstrap-ordering.md).
2. **Retrieval step**
Call the retriever with explicit metric and consistent analyzer. Return `snippet_id`, `section_id`, `source_url`, `offsets`, `tokens`.
3. **ΔS probe**
Compute ΔS(question, retrieved). If ΔS ≥ 0.60 set `needs_fix=true`.
4. **Answer step**
LLM reads TXT OS and the WFGY schema. Enforce cite-then-explain with the retrieved snippet set.
5. **Trace sink**
Store `question`, `ΔS`, `λ_state`, `INDEX_HASH`, `snippet_id`, `dedupe_key`.
---
## Copy-paste prompt for the webhook LLM step
```
You have TXT OS and the WFGY Problem Map loaded.
My watsonx Assistant context:
- action: {action_name}
- variables: {name: value, ...}
- retrieved: {k} snippets with fields {snippet_id, section_id, source_url, offsets}
User question: "{user_question}"
Do:
1) Enforce cite-then-explain. If citations are missing or cross-section, fail fast and return the smallest structural fix.
2) If ΔS(question, retrieved) ≥ 0.60, propose the minimal repair, referencing:
retrieval-playbook, retrieval-traceability, data-contracts, rerankers.
3) Return JSON:
{ "answer": "...", "citations": [...], "λ_state": "→|←|<>|×", "ΔS": 0.xx, "next_fix": "..." }
Keep it short and auditable.
```
---
## Test checklist before launch
* Three paraphrases hit coverage ≥ 0.70 on the same target section.
* ΔS(question, retrieved) ≤ 0.45 for each.
* λ convergent across two seeds.
* First-call path after deploy passes the warm-up fence.
* Live probes alert when ΔS ≥ 0.60 or λ flips.
