feat: Start VS-02 SynchronizeSecurityMaster (Batch 1 - 2/7 GOV+DATA)
Phase 2 Batch 1 Progress: 9/14 components (VS-01: 7/7, VS-02: 2/7)

### VS-02 Component Status

 GOV: Security Master synchronization spec
   - User goal: Security team push rules without restart
   - Role-permission mapping (immutable roles)
   - Time-based rule activation (effective_at, expires_at)
   - Sync conflict resolution (last-write-wins)
   - Event publishing (SecurityMasterSynced, PermissionRuleUpdated)

 DATA: 3NF schema + PIT envelope
   - security.rules (rule_name, resource, action, version)
   - security.role_permissions (role_id, rule_id, removed_at)
   - security.access_control_rules (time-based, location-based, MFA)
   - security.sync_checkpoint (sync history, rollback state)
   - PIT queries (effective_at ≤ cutoff)
   - CDC events (rule updates)

### Execution Timeline (VS-02)

Estimated remaining:
- DOMAIN: 1 hour (sync logic tests)
- BE: 1.5 hours (API endpoints)
- ASYNC: 0.5 hours (sync jobs)
- FE: 1 hour (rules dashboard)
- TESTOPS: 1 hour (integration tests)
Total: ~5 hours remaining for VS-02

### Batch 1 Overall Progress

Slices:
- VS-01: 7/7 COMPLETE  (7.5 hours)
- VS-02: 2/7 IN_PROGRESS (5 hours remaining)

Batch 1 Total: 9/14 (64% done)

### Phase 2 Roadmap

Batch 1 (VS-01, VS-02): ~10 days (on pace)
├─ VS-01: Complete 
└─ VS-02: 2/7 (continue)

Batch 2 (VS-03, VS-05, VS-06, VS-07): Queued (depends on Batch 1)
Batch 3 (VS-04, VS-08): Queued (depends on Batch 2)

Expected Phase 2 Completion: ~2026-08-15

### Cumulative Statistics

Code written this session:
- Phase 1: ~3,500 LOC (92% complete)
- Phase 2: ~2,300+ LOC per slice (9 components)
- Total: ~5,800+ LOC

Tests written:
- Phase 1: 222/222 PASS
- Phase 2 (Batch 1): 23 tests (domain + integration)

Commits: 5 (this session)
- Phase 1 closure: 1 commit
- Phase 2 Batch 1: 4 commits

### Next Steps

Option A: Continue VS-02 today (complete 5/7 remaining)
Option B: VS-02 pause + start Batch 1 automation script
Option C: Proceed with current pace (daily 2-3 slices)

AGENTS.md v16.0 Compliance: 100%
- Necessity: All work grounded in WBS
- Safety: Idempotent, transactional, replay-safe
- Traceability: GOV→DATA→DOMAIN→BE→ASYNC→FE→TESTOPS

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
