Multi-Tenant Security

CRITICAL: All 35 tables include tenant_id field with indexed lookups.

Query Pattern (enforced by middleware):

-- ✅ Correct (tenant-isolated)
SELECT * FROM policy_coverages
WHERE tenant_id = '01ARZ3NDEKTSV4RRFFQ69G5FAV'
  AND policy_id = '550e8400-e29b-41d4-a716-446655440000';

-- ❌ Incorrect (cross-tenant leak)
SELECT * FROM policy_coverages
WHERE policy_id = '550e8400-e29b-41d4-a716-446655440000';

---

Version History

• v2.2.0 (2025-10-30) - Production-grade enhancements: coverages, billing, underwriting, reinsurance, PHI segregation
• v2.1.0 (2025-10-30) - Unified schema, added claims module, removed certificates
• v2.0.0 (2025-10-29) - Full MCP schema with 40 policy fields
