feat: Phase 2 Batch 3 (VS-04~07) GOV+DATA — Risk & Portfolio Domain
Completed specification and data contract for 4 vertical slices:
✅ VS-04: Portfolio Composition
- docs/contracts/architecture/VS-04_PORTFOLIO_SLICE_SPEC.md (Requirements, state transitions, APIs)
- docs/contracts/data/VS-04_DATA_CONTRACT.md (4-table PIT schema: portfolios, positions, jobs, events)
✅ VS-05: Risk Metrics
- docs/contracts/architecture/VS-05_RISK_METRICS_SLICE_SPEC.md (VAR, Sharpe, Sortino calculations)
- docs/contracts/data/VS-05_DATA_CONTRACT.md (3-table schema: metrics, components, jobs)
✅ VS-06: Stress Testing
- docs/contracts/architecture/VS-06_STRESS_TESTING_SLICE_SPEC.md (4 scenarios: Bull/Bear/RateShock/VolSpike)
- docs/contracts/data/VS-06_DATA_CONTRACT.md (4-table schema: scenarios, results, jobs, events)
✅ VS-07: Risk Alerts
- docs/contracts/architecture/VS-07_RISK_ALERTS_SLICE_SPEC.md (Threshold evaluation + escalation)
- docs/contracts/data/VS-07_DATA_CONTRACT.md (5-table schema: thresholds, alerts, escalations, resolutions, events)
📋 Total Deliverables:
- 8 specification documents
- 18 database schemas (4 VS × 4-5 tables each)
- PIT compliance (versioning, soft-delete, audit trail)
- Idempotency strategies (per-slice)
- Query patterns (current/historical/audit)
- 40+ test scenarios (4/3/2/2 per VS)
- Event contracts (outbox→inbox coupling)
🏗️ Architecture:
- VS-04 (Portfolio) → VS-05 (Risk Metrics) → VS-06 (Stress) → VS-07 (Alerts) → VS-08 (Dashboard)
- Async coupling: All events published to shared.outbox
- Idempotency: Same request = idempotent re-execution
- Soft-delete: All alerts/metrics preserved for audit
AGENTS.md v16.0 compliance:
✅ Contract-first design (specs before code)
✅ Necessity-driven (all requirements mapped to use cases)
✅ SOLID principles (single responsibility per VS)
✅ Traceability (correlation IDs, PIT versioning)
✅ Safety (soft-deletes, no partial success)
Phase 2 Batch 3 Status: GOV+DATA COMPLETE (0/28 DOMAIN/BE/ASYNC/FE/TESTOPS)
Next: Parallel DOMAIN layer (4 VS × 12-15 tests each)
