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
Latency-based failover picks wrong region	Bootstrap not locked to residency fences	bootstrap-ordering.md
Snippets without residency label	Schema missing `region_tag` field	data-contracts.md

Fix in 60 seconds

Probe ΔS across regions: ask the same Q, check EU vs US vs APAC stores.
Enforce residency schema: all payloads must carry region_tag.
Rebuild index replicas with locked residency metadata.
Test λ stability with paraphrases inside each residency scope only.

Copy-paste schema (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 and eval_rag_precision_recall.md for deep remediation.
