# Data Residency — Enterprise Knowledge Governance

Guardrails and fix patterns to enforce jurisdiction and residency rules on enterprise knowledge pipelines. Use this page when retrieval or storage drifts across regions and breaks compliance with local data laws.

---

## When to use this page
- Snippets come from indexes hosted outside the allowed jurisdiction.  
- AI answers blend EU-only and US-only data without labels.  
- Multi-region retrievers collapse into lowest-latency store instead of correct residency.  
- Replicas sync to unapproved clouds or regions.  

---

## Core acceptance targets
- ΔS(question, retrieved) ≤ 0.45 within jurisdiction.  
- ≥0.70 coverage for the correct residency domain.  
- λ convergent across three paraphrases and two seeds.  
- Every snippet labeled with `{region_tag, residency_scope, audit_hash}`.

## Typical residency problems → exact fix

| Symptom | Likely cause | Open this |
|---------|--------------|-----------|
| EU vs US content blended | Index replicas lack residency tags | [retrieval-traceability.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-traceability.md) |
| Latency-based failover picks wrong region | Bootstrap not locked to residency fences | [bootstrap-ordering.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/bootstrap-ordering.md) |
| Snippets without residency label | Schema missing `region_tag` field | [data-contracts.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md) |

---

## Fix in 60 seconds
1. **Probe ΔS across regions**: ask the same Q, check EU vs US vs APAC stores.  
2. **Enforce residency schema**: all payloads must carry `region_tag`.  
3. **Rebuild index replicas** with locked residency metadata.  
4. **Test λ stability** with paraphrases inside each residency scope only.  

---

## Copy-paste schema (JSON)

```json
{
  "snippet_id": "KB-8837",
  "region_tag": "eu-central",
  "residency_scope": "gdpr_lock",
  "audit_hash": "sha256:...",
  "text": "..."
}
````

---

## Escalate when

* ΔS ≥ 0.60 across paraphrases even with region locks.
* Index routing repeatedly breaks residency rules.
* Legal audit requires external certification.

Use [retrieval-playbook.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-playbook.md) and [eval\_rag\_precision\_recall.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/eval/eval_rag_precision_recall.md) for deep remediation.
