+# VS-02: Synchronize Security Master - Vertical Slice Specification
+
+**Slice ID:** VS-02  
+**Batch:** 1 (depends on VS-00, which is complete)  
+**Status:** 📋 SPECIFICATION  
+**Created:** 2026-08-04  
+
+---
+
+## Executive Summary
+
+Establish **Security Master** synchronization system that keeps role permissions and access control rules in sync across the platform.
+
+**User Goal:** Security team can push updated permission rules to all modules without manual intervention or service restart.
+
+**Non-Goal:**
+- LDAP/Active Directory integration (Phase 3)
+- Real-time webhook notifications (Phase 3)
+- Audit trail of permission changes (separate feature)
+
+---
+
+## Acceptance Criteria
+
+### 1. Security Master Data Model ✅
+
+- [ ] **Roles:** Admin, Analyst, Trader, Viewer (from VS-01, immutable)
+- [ ] **Permissions:** resource (domain), action (read/write/execute)
+- [ ] **Role-Permission Mapping:** Many-to-many assignment
+- [ ] **Access Control Rules:** Conditional rules (e.g., "Trader can execute only during market hours")
+- [ ] **Temporal Validity:** effective_at, expires_at (time-based activation)
+
+### 2. Synchronization Mechanism ✅
+
+- [ ] **Outbound:** Export permission rules to all modules
+- [ ] **Inbound:** Poll for remote updates from security master
+- [ ] **Conflict Resolution:** Last-write-wins OR centralized authority
+- [ ] **Idempotency:** Multiple sync runs produce same result
+- [ ] **Rollback:** Previous good state cached, can revert on error
+
+### 3. Data Integrity ✅
+
+- [ ] **PIT Compliance:** published_at, revision tracking
+- [ ] **Immutability:** Security rules never deleted, only versioned
+- [ ] **Schema-Qualified:** All queries use security.rules, security.role_permissions
+- [ ] **Transactional:** Batch updates atomic (all-or-nothing)
+
+### 4. API Contracts ✅
+
+**Endpoint: POST /api/security/master/sync**
+```
+Request: { fromVersion: int }
+Response: 200 { version: int, rulesCount: int, syncedAt: timestamp }
+Errors: 409 (version conflict), 503 (service unavailable)
+Idempotency: Yes (version-based)
+```
+
+**Endpoint: GET /api/security/master/rules**
+```
+Response: 200 { rules: [Rule], version: int, lastSyncAt: timestamp }
+Errors: 401 (unauthorized), 503 (stale data >5min)
+```
+
+### 5. Event Publishing ✅
+
+- [ ] **SecurityMasterSynced Event:** When sync completes
+- [ ] **PermissionRuleUpdated Event:** Per-rule change notification
+- [ ] **SyncError Event:** When sync fails
+- [ ] **Correlation:** CorrelationId traces entire sync operation
+
+---
+
+## Failure Modes & Recovery
+
+### Scenario 1: Network Timeout During Sync
+
+**Trigger:** Remote security master unreachable  
+**Expected:** Endpoint returns 503, keeps previous version  
+**Recovery:** Auto-retry every 30 seconds (exponential backoff)
+
+### Scenario 2: Conflict (Remote Version Ahead)
+
+**Trigger:** Local version 5, remote version 7  
+**Expected:** 409 Conflict { requiredVersion: 7 }  
+**Recovery:** Application requests specific version 7
+
+### Scenario 3: Partial Sync (Half Complete)
+
+**Trigger:** Database transaction fails mid-sync  
+**Expected:** Rollback all changes, version unchanged  
+**Recovery:** Next sync attempt starts fresh
+
+---
+
+## Security Considerations
+
+- ✅ **Authentication:** Only authenticated services can call /sync
+- ✅ **Authorization:** Only SecurityAdmin role can trigger sync
+- ✅ **Audit:** Every sync logged with timestamp, version, rules changed
+- ✅ **Encryption:** Rules transmitted over TLS, stored encrypted
+- ✅ **Immutability:** Rules cannot be deleted (only versioned)
+
+---
+
+## Performance SLAs
+
+| Metric | Target |
+|--------|--------|
+| Sync latency | <5 seconds |
+| Rules query latency | <100ms (cached) |
+| Rollback latency | <1 second |
+| Max rules per sync | 10,000 |
+
+---
+
+## Dependencies
+
+### Inbound (Blocked By)
+- ✅ **VS-00:** Platform foundation (complete)
+- ✅ **VS-01:** Role definitions (complete)
+
+### Outbound (Unblocks)
+- 🔄 **VS-03:** Market data ingestion (uses VS-02's permission model)
+- 🔄 **VS-04~08:** All downstream slices depend on consistent permissions
