# AWS Bedrock: Guardrails and Fix Patterns

Use this page when failures look provider‐specific in AWS Bedrock. Typical cases are mismatched model routing (Claude, Llama, Mistral, etc.), JSON schema drift, tool-call latency, throttle ceilings, or region/IAM issues that masquerade as “reasoning bugs.” Each fix maps to WFGY pages so you can verify with measurable targets.

## Fix in 60 seconds

1) **Measure ΔS**
- Compute ΔS(question, retrieved) and ΔS(retrieved, expected anchor).
- Targets: stable < 0.40, transitional 0.40–0.60, risk ≥ 0.60.

2) **Probe with λ_observe**
- Vary k ∈ {5, 10, 20}. Flat high curve → index or metric mismatch.
- Reorder prompt headers. If ΔS spikes, lock the schema.

3) **Apply the module**
- Retrieval drift → **BBMC** + **Data Contracts**.
- Reasoning collapse → **BBCR bridge** + **BBAM variance clamp**.
- Dead ends in long runs → **BBPF** alternate path.

4) **Verify**
- Coverage to target section ≥ 0.70.
- ΔS ≤ 0.45 within three paraphrases.
- λ stays convergent across seeds and sessions.

## Typical Bedrock breakpoints (and the right fix)

- **Model routing not what you think**  
  Invoking `anthropic.claude-*` vs `meta.llama-*` vs `mistral.*` changes tokenizer, max tokens, and tool-call behavior. If outputs flip between routes, pin the model id per task, then re-check with [Logic Collapse](https://github.com/onestardao/WFGY/blob/main/ProblemMap/logic-collapse.md) and [Retrieval Traceability](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-traceability.md).

- **JSON schema drift in tool use**  
  Claude via Bedrock is strict on JSON when `toolChoice` is forced. Lock the output schema with [Data Contracts](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md) and add a BBCR bridge step that rejects non-conformant fields.

- **Latency spikes → hidden timeouts**  
  Region hop or Guardrails policy checks can add latency. Use small test prompts and trace λ per step. If λ diverges only when tools are enabled, set a shorter planning window and split tools by namespace. See [ops/live_monitoring_rag.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/ops/live_monitoring_rag.md).

- **Bedrock “Guardrails” over-filtering**  
  Safety filters can truncate citations or code blocks. If citations vanish, lower the filter aggressiveness, then enforce source-only answers with [Retrieval Traceability](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-traceability.md) and the SCU pattern ([symbolic constraint unlock](https://github.com/onestardao/WFGY/blob/main/ProblemMap/patterns/pattern_symbolic_constraint_unlock.md)).

- **Context windows differ across routes**  
  If the same prompt collapses only on one model family, shrink the active window and re-chunk. Validate with [Context Drift](https://github.com/onestardao/WFGY/blob/main/ProblemMap/context-drift.md) and [Entropy Collapse](https://github.com/onestardao/WFGY/blob/main/ProblemMap/entropy-collapse.md).

- **IAM or region misconfig → “reasoning” looks random**  
  On silent fallbacks or throttling, the agent loops. Install a BBCR checkpoint that asserts model id, region, and rate state before long chains. If it fails, exit early and surface infra status. See [bootstrap-ordering](https://github.com/onestardao/WFGY/blob/main/ProblemMap/bootstrap-ordering.md) and [predeploy-collapse](https://github.com/onestardao/WFGY/blob/main/ProblemMap/predeploy-collapse.md).

## Provider knobs and minimal recipes

- **Pin model and cap tokens**
  - One task, one model id. Keep a per-task max tokens map.
  - If you must swap models, add BBPF to branch at the planner step, not mid-reasoning.

- **Force citations first**
  - Use citation-first headers and the snippet schema from [Retrieval Traceability](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-traceability.md).  
  - Reject answers without snippet ids. That alone removes most “looks like hallucination” cases.

- **Defuse prompt injection**
  - Apply the injection checklist and keep tools off until the source set is locked. See [prompt-injection.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/prompt-injection.md).

- **Rerank aggressively**
  - Many Bedrock routes benefit from tighter top-k ordering. Use [Rerankers](https://github.com/onestardao/WFGY/blob/main/ProblemMap/rerankers.md) and then re-test ΔS across 3 paraphrases.

---

## Escalation path

- If ΔS flat-high across k and models → rebuild index with new metric. Check [embedding-vs-semantic](https://github.com/onestardao/WFGY/blob/main/ProblemMap/embedding-vs-semantic.md).
- If agent deadlocks with tools → split memory namespaces and add timeouts. See [Multi-Agent Problems](https://github.com/onestardao/WFGY/blob/main/ProblemMap/Multi-Agent_Problems.md).
- If first prod call fails after deploy → confirm ordering with [bootstrap-ordering](https://github.com/onestardao/WFGY/blob/main/ProblemMap/bootstrap-ordering.md) and [deployment-deadlock](https://github.com/onestardao/WFGY/blob/main/ProblemMap/deployment-deadlock.md).

## Copy-paste prompt (safe)

```

I uploaded TXT OS and the WFGY ProblemMap files.

My Bedrock issue:

* symptom: \[brief]
* traces: \[ΔS(question,retrieved)=..., ΔS(retrieved,anchor)=..., λ states]

Tell me:

1. which layer is failing and why,
2. which exact fix page to open from this repo,
3. the minimal steps to push ΔS ≤ 0.45 and keep λ convergent,
4. how to verify the fix with a reproducible test.

Use BBMC/BBPF/BBCR/BBAM when relevant.

```

### Acceptance targets
- Coverage to target section ≥ 0.70  
- ΔS(question, retrieved) ≤ 0.45 within three paraphrases  
- λ remains convergent across seeds and sessions  
- E_resonance flat on long windows
