# Phase 2 Batch 3-4: Risk & Portfolio Domain (VS-04~08)
## 📋 Overview
**Domain:** Portfolio composition, risk metrics, stress testing, alerts, dashboard
**Pattern:** Vertical Slice (GOV → DATA → DOMAIN → BE → ASYNC → FE → TESTOPS)
**Strategy:** AGENTS.md v16.0 WBS Optimization — execute all non-blocking tasks immediately
---
## 🏗️ Component Structure
| VS | Name | Purpose | Data Model | Endpoint | Event |
|----|------|---------|------------|----------|-------|
| **VS-04** | Portfolio Composition | Aggregate positions & risk weights | `portfolios.*` (PIT) | POST /api/portfolio/rebalance | PortfolioRebalanced |
| **VS-05** | Risk Metrics | VAR, Sharpe, Sortino calculations | `risk_metrics.*` (PIT) | GET /api/portfolio/{id}/risk | RiskMetricsCalculated |
| **VS-06** | Stress Testing | Scenario analysis (bull/bear/rate-shock) | `stress_tests.*` (append-only) | POST /api/portfolio/{id}/stress | StressTestCompleted |
| **VS-07** | Risk Alerts | Threshold breach + escalation | `risk_alerts.*` (soft-delete) | GET /api/portfolio/{id}/alerts | RiskAlertTriggered |
| **VS-08** | Risk Dashboard | Real-time risk aggregation + UI | `risk_dashboard_agg` (denorm) | GET /api/dashboard/risk | (read-only) |
---
## 🔗 Dependencies & Parallelization
```
VS-04 (Portfolio Composition)
VS-05 (Risk Metrics) ← requires portfolio data
VS-06 (Stress Testing) ← requires risk metrics
VS-07 (Risk Alerts) ← requires stress results
VS-08 (Risk Dashboard) ← aggregates all above
```
**Parallelizable:**
- Each VS can be GOV+DATA defined in parallel (9 docs in parallel)
- DOMAIN logic for VS-04 & VS-05 in parallel (once specs done)
- BE endpoints for all VS in parallel (once DOMAIN ready)
**Critical Path:**
- VS-04 DATA must complete before VS-05 DOMAIN
- VS-05 DOMAIN must complete before VS-06 BE
- Total: Sequential on hot path, but 40% parallelization possible
---
## 📅 WBS Schedule (Optimized)
**Day 1 (Today): GOV + DATA (All 5 VS)**
- VS-04: `VS04_PORTFOLIO_SLICE_SPEC.md` + `VS04_DATA_CONTRACT.md`
- VS-05: `VS05_RISK_METRICS_SLICE_SPEC.md` + `VS05_DATA_CONTRACT.md`
- VS-06: `VS06_STRESS_TESTING_SLICE_SPEC.md` + `VS06_DATA_CONTRACT.md`
- VS-07: `VS07_RISK_ALERTS_SLICE_SPEC.md` + `VS07_DATA_CONTRACT.md`
- VS-08: `VS08_RISK_DASHBOARD_SLICE_SPEC.md` + (no separate data schema)
- **Deliverable:** 9 spec documents, schema validation complete
**Day 2: DOMAIN (VS-04, 05, 06, 07)**
- VS-04: Portfolio aggregation logic (12 tests)
- VS-05: Risk calculation logic (15 tests)
- VS-06: Scenario application logic (10 tests)
- VS-07: Alert threshold evaluation (8 tests)
- **Parallel:** All 4 can run in parallel after specs
- **Deliverable:** 45 unit tests, 4/4 domains PASS
**Day 3: BE + ASYNC (All 5 VS)**
- VS-04: Rebalance endpoint + Hangfire job
- VS-05: Risk metrics fetch endpoint + background calculator
- VS-06: Stress test trigger + async batch processing
- VS-07: Alert query endpoint + event publisher
- VS-08: Aggregation endpoint (read-only)
- **Deliverable:** 5 endpoints, 5 async jobs, 20 tests

## 🎯 Acceptance Criteria (AGENTS.md v16.0)
**Per VS:**
- ✅ Contract-first: Specs + schema before code
- ✅ SOLID: No cross-cutting concerns, single responsibility
- ✅ Complexity: Cyclomatic complexity ≤ 10 (Policy exceptions)
- ✅ Idempotency: All jobs + scenarios replay-safe
- ✅ Audit: Correlation IDs, event published, PIT versioned
- ✅ Safety: Transaction boundaries, soft-deletes, no partial success
- ✅ Testing: Unit → Integration → Data → E2E coverage
- ✅ Traceability: ADR links, evidence preserved
**Cross-VS:**
- ✅ No SELECT * or direct module-to-module queries
- ✅ Async coupling via Outbox/Inbox (no direct function calls)
- ✅ Tech debt registered (if any deferral)
- ✅ Architecture tests pass
- ✅ All prior tests still pass (no regressions)
---
## 📊 Success Metrics
| Metric | Target | Checkpoint |
|--------|--------|------------|
| Test Pass Rate | 100% | End of each day |
| Architecture Violations | 0 | Before commit |
| Tech Debt Registered | 100% | In PR description |
| Code Review Comments | <5 | Per PR |
| Build Time | <5s | Continuous |
---
## 🚀 Execution Plan (This Session)
**Phase 2 Batch 3 Start (VS-04~07):**
1. ✅ Confirm domain scope (Risk & Portfolio) — **DONE**
2. ⏳ GOV + DATA (9 docs, parallel) — **START NOW**
3. ⏳ DOMAIN (4 VS, parallel) — **Follow after specs**
4. ⏳ BE + ASYNC (5 endpoints, parallel) — **Follow after domain**
5. ⏳ FE + TESTOPS (5 components, Batch 3) — **Follow after BE**
**Phase 2 Batch 4 (VS-08):**
6. ⏳ Risk Dashboard (depends on all others)
7. ⏳ Final integration testing
---
## 📝 Notes
- **SSH Tunnel:** Required for any DB-backed integration tests. Keep open during dev.
- **Parallel Execution:** GOV+DATA can be written concurrently; post in 5 separate docs
- **Debt Threshold:** Keep new debt <20 impact points per batch (manage quarterly paydown)
- **Git Strategy:** One commit per component (GOV+DATA) or (DOMAIN) or (BE+ASYNC), then squash if needed

**User Goal:** "I need a unified view of my entire portfolio risk profile in one dashboard"
---
## Non-Goals
- Custom dashboard builder (fixed layout)
- Real-time market tick updates (EOD refresh acceptable)
- Mobile-optimized view (desktop focus)
---
## Requirements
### Functional

## RBAC & Authorization
| Operation | Role | Condition |
|-----------|------|-----------|
| VIEW dashboard | DataReader | Own portfolio only |
| TRIGGER refresh | DataAnalyst | Manual override |
---
## Testing Strategy
1. **Unit:** Data aggregation logic (5 tests)
2. **Integration:** DB → aggregation → API (4 tests)
3. **E2E:** Full dashboard load + SignalR push (2 tests)
4. **Golden:** Known portfolio → expected snapshot
---
## Assumptions
- All VS-04~07 data is fresh (<1hr old)
- SignalR hub is available (separate deployment)
- Portfolio ID is authenticated via RBAC
---
## Vertical Slice Boundary
**In Scope:** Aggregation logic + API endpoint + real-time updates
**Out of Scope:** Custom drill-down reports, export functionality
**Rationale:** Minimal, read-only aggregation; all mutations in VS-04~07

# VS-08: Risk Dashboard — Data Contract
**Domain:** Comprehensive Risk Monitoring
**Pattern:** Point-in-Time (PIT) Read Model + Event Stream

## Schema Overview
| Table | Purpose | Ownership | TTL |
|-------|---------|-----------|-----|
| `risk_management.dashboard_snapshots` | Cached aggregations (portfolio + risk + stress + alerts) | VS-08 | <1hr |
| `risk_management.vw_dashboard_data` | JOIN view (portfolio_positions + risk_metrics + stress + alerts) | Read-only | — |
### dashboard_snapshots (PIT Write Model)
Cached snapshot of portfolio risk profile, refreshed on-demand or event-triggered.
```sql
CREATE TABLE IF NOT EXISTS risk_management.dashboard_snapshots (
id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
portfolio_id UUID NOT NULL,
snapshot_date DATE NOT NULL,
-- Portfolio aggregates
total_portfolio_value DECIMAL(18, 2) NOT NULL,

-- Risk metrics (VS-05)
var95 DECIMAL(18, 2),
sharpe_ratio NUMERIC(5, 2),
sortino_ratio NUMERIC(5, 2),

-- Audit
published_at TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
revision INT DEFAULT 1,
source_component VARCHAR(50) NOT NULL, -- 'api' or 'event'
CONSTRAINT fk_portfolio FOREIGN KEY (portfolio_id)
REFERENCES risk_management.portfolios(id),
CONSTRAINT unique_snapshot_per_portfolio_per_date
UNIQUE(portfolio_id, snapshot_date, published_at DESC)
);
CREATE INDEX idx_dashboard_portfolio_date
ON risk_management.dashboard_snapshots(portfolio_id, snapshot_date DESC);
```
### vw_dashboard_data (Read-Only JOIN View)
Real-time aggregation view joining VS-04~07 source tables. Used by API endpoint for <500ms latency.
```sql
CREATE OR REPLACE VIEW risk_management.vw_dashboard_data AS
SELECT
p.portfolio_id,
p.snapshot_date,
-- Portfolio (VS-04)
COUNT(DISTINCT pp.symbol) as position_count,
SUM(pp.market_value) as total_portfolio_value,
-- Risk Metrics (VS-05)
(SELECT var95 FROM risk_management.risk_metrics
WHERE portfolio_id = p.portfolio_id
AND published_at <= CURRENT_TIMESTAMP
AND removed_at IS NULL
ORDER BY published_at DESC LIMIT 1) as var95,
(SELECT sharpe_ratio FROM risk_management.risk_metrics
WHERE portfolio_id = p.portfolio_id
AND published_at <= CURRENT_TIMESTAMP
AND removed_at IS NULL
ORDER BY published_at DESC LIMIT 1) as sharpe_ratio,
-- Stress (VS-06)
(SELECT portfolio_loss_percent FROM risk_management.stress_test_results
WHERE portfolio_id = p.portfolio_id
AND scenario_name = 'bear'
AND published_at <= CURRENT_TIMESTAMP
ORDER BY published_at DESC LIMIT 1) as bear_loss_percent,
-- Alerts (VS-07)
COUNT(CASE WHEN ra.severity = 'Warning' THEN 1 END) as warning_alert_count
FROM risk_management.portfolios p
LEFT JOIN risk_management.portfolio_positions pp
ON p.id = pp.portfolio_id
AND pp.published_at <= CURRENT_TIMESTAMP
AND pp.removed_at IS NULL
LEFT JOIN risk_management.risk_alerts ra
ON p.id = ra.portfolio_id
AND ra.published_at <= CURRENT_TIMESTAMP
AND ra.removed_at IS NULL
AND ra.resolved_at IS NULL
WHERE p.published_at <= CURRENT_TIMESTAMP
AND p.removed_at IS NULL
GROUP BY p.id, p.snapshot_date;
```
---
## Query Patterns
### 1. Fetch Dashboard Snapshot (GET /api/dashboard/risk)
**Source:** `dashboard_snapshots` cache OR `vw_dashboard_data` (fallback)
```sql
-- Try cache first (< 1 hour)
SELECT * FROM risk_management.dashboard_snapshots
WHERE portfolio_id = $1
AND snapshot_date >= CURRENT_DATE - INTERVAL '1 hour'
AND published_at <= $2
ORDER BY published_at DESC
LIMIT 1;
-- Fallback: read-only view (real-time)
SELECT * FROM risk_management.vw_dashboard_data
WHERE portfolio_id = $1
AND snapshot_date = CURRENT_DATE;
```
### 2. Refresh Dashboard on Event
**Trigger:** PortfolioRebalanced, PortfolioMetricsCalculated, StressTestCompleted, AlertEscalated
```sql
INSERT INTO risk_management.dashboard_snapshots (
portfolio_id, snapshot_date, total_portfolio_value, position_count,
var95, sharpe_ratio, alert_warning_count, source_component, published_at
)
SELECT
portfolio_id, CURRENT_DATE,
COALESCE(total_portfolio_value, 0),
COALESCE(position_count, 0),
var95, sharpe_ratio, warning_alert_count,
'event', CURRENT_TIMESTAMP
FROM risk_management.vw_dashboard_data
WHERE portfolio_id = $1
ON CONFLICT (portfolio_id, snapshot_date, published_at DESC)
DO UPDATE SET
total_portfolio_value = EXCLUDED.total_portfolio_value,
revision = revision + 1,
published_at = CURRENT_TIMESTAMP;
```
### 3. List All Positions (for dashboard visualization)
```sql
SELECT symbol, quantity, market_price, market_value, weight_percent
FROM risk_management.portfolio_positions
WHERE portfolio_id = $1
AND published_at <= $2
AND removed_at IS NULL
ORDER BY weight_percent DESC;
```
### 4. List Active Alerts
```sql
SELECT alert_id, threshold_type, current_value, severity, message
FROM risk_management.risk_alerts
WHERE portfolio_id = $1
AND published_at <= $2
AND removed_at IS NULL
AND resolved_at IS NULL
ORDER BY severity DESC, triggered_at DESC;
```
---
## Idempotency & Concurrency
**Idempotency Key:** `(portfolio_id, snapshot_date, source_component)`
- Cache refresh from event is idempotent (no duplicates via UPSERT)
- Multiple concurrent API calls return same cached result
- View queries are always consistent (no transaction isolation needed)
---
## Performance SLA
| Query | Source | Latency | Cache |
|-------|--------|---------|-------|
| Dashboard snapshot | `dashboard_snapshots` | <100ms | 1 hour |
| Fallback (real-time) | `vw_dashboard_data` | <500ms | — |
| Active alerts | Direct table | <50ms | — |
| Positions table | Direct table | <100ms | — |
**Indexes:**
```sql
CREATE INDEX idx_dashboard_portfolio_date
ON risk_management.dashboard_snapshots(portfolio_id, snapshot_date DESC);
CREATE INDEX idx_portfolio_positions_portfolio_date
ON risk_management.portfolio_positions(portfolio_id, trading_date DESC);
CREATE INDEX idx_risk_alerts_portfolio_resolved
ON risk_management.risk_alerts(portfolio_id, resolved_at, published_at DESC);
```
---
## Event Publishing (Outbox Integration)
When dashboard is refreshed, emit event for SignalR push:
**Event: DashboardUpdated**
```json
{
"eventType": "DashboardUpdated",
"portfolioId": "550e8400-e29b-41d4-a716-446655440001",
"changedComponents": ["riskMetrics", "activeAlerts"],
"snapshotId": "550e8400-e29b-41d4-a716-446655440002",
"updatedAt": "2026-08-05T10:05:00Z"
}
```
Published via: `shared.outbox` → Hangfire → SignalR Hub → `DashboardHub.UpdateDashboard(portfolioId)`
---
## Testing Strategy
1. **Unit:** Aggregation SQL queries (with mock data)
2. **Integration:** Dashboard endpoint → cache hit/miss → DB fallback
3. **E2E:** Event trigger → dashboard update → SignalR push
4. **Golden:** Known portfolio snapshot → expected aggregates (variance <0.01%)
---
## Assumptions
- All source tables (VS-04~07) maintain PIT audit trail
- `published_at <= cutoff` enforced on all source reads
- Cache TTL managed by application (not DB expiry)
- SignalR hub configured separately; dashboard job just publishes event
---
## Migration
**DbUp Script:** `0034_VS08_DashboardSchema.sql`
```sql
-- Create tables, views, indexes
-- Seed initial cache from existing data if present
-- Grant SELECT on views to DataReader role
```
