At every governance gate (before execution)\n2. At every Spine query (before data access)\n3. At every communication (before delivery)\n4. At every reconciliation (before memory promotion)\n\n---\n\n## Purpose Limitation\n\nData is used only for stated purposes:\n\n| Purpose | Scope |\n|---------|-------|\n| **Business operations** | Day-to-day work execution |\n| **Analytics** | Reporting and insights |\n| **AI reasoning** | Twin and agent context |\n| **Compliance** | Regulatory requirements |\n| **Audit** | Investigation and review |\n\n### Purpose Rules\n\n- Data tagged with permitted purposes\n- Access checked against purpose tags\n- Purpose violations are logged and blocked\n- Purpose can be updated with governance approval\n\n---\n\n## Consent Management\n\n| Consent Type | Description |\n|-------------|-------------|\n| **Data collection** | Consent to collect data from systems |\n| **Data processing** | Consent to process data for AI reasoning |\n| **Data sharing** | Consent to share data across domains |\n| **Data retention** | Consent to retain data beyond active use |\n\n---\n\n## Data Classification\n\n| Classification | Description | Handling |\n|---------------|-------------|----------|\n| **Public** | No restriction | Standard access |\n| **Internal** | Organization-wide | Auth required |\n| **Confidential** | Role-restricted | Encryption + audit |\n| **Restricted** | Named-person access | MFA + encryption + audit + DLP |\n\n---\n\n## Audit Trail\n\nEvery action in SpineWorkspace produces an audit record:\n\n```typescript\ninterface AuditRecord {\n  id: string;\n  tenantId: string;\n  timestamp: string;\n  actor: ActorRef;\n  action: string;\n  resource: string;\n  resourceId: string;\n  outcome: 'success' | 'failure' | 'denied';\n  details: Record<string, unknown>;\n  ipAddress?: string;\n  userAgent?: string;\n}\n```\n\n### Audit Rules\n\n- Audit records are append-only\n- Audit records cannot be modified or deleted\n- Audit records are stored in the Audit Store\n- Audit records are retained per compliance policy\n\n---\n\n## Retention\n\n| Data Type | Default Retention |\n|-----------|-------------------|\n| **Operational data** | Active + 90 days |\n| **Communication logs** | Active + 1 year |\n| **Audit records** | 7 years |\n| **Memory entries** | Active + 2 years |\n| **Archived data** | Per compliance policy |\n\n---\n\n## Compliance\n\nSpineWorkspace supports compliance with:\n\n| Regulation | Support |\n|-----------|---------|\n| **GDPR** | Data subject rights, consent management, right to erasure |\n| **SOC 2** | Access controls, audit trail, monitoring |\n| **HIPAA** | PHI handling, BAA support, encryption |\n| **CCPA** | Consumer rights, data inventory |\n| **ISO 27001** | Security controls, risk management |\n"}
