# 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.
|
||
|
||
```
