|
|
|
|
## ✅ Completed (Pre-Merge)
|
|
|
|
### Architecture & Code Quality
|
|
- [x] AGENTS.md v16.0 compliance verified (all 13 decision criteria)
|
|
- [x] Vertical Slice pattern: Complete endpoint-to-database features
|
|
- [x] Module isolation: Cross-module coupling via Outbox/Inbox pattern only
|
|
- [x] Async coupling: ShadowRunJob → IOutboxWriter → OutboxPollerJob → DownstreamConsumerJob
|
|
- [x] Zero new technical debt (all deferred work documented)
|
|
- [x] Code analysis: CA1822, CA1873 rules suppressed per CLAUDE.md
|
|
|
|
### Testing
|
|
- [x] Unit tests: 17/17 ModelOperations ✓
|
|
- [x] Unit tests: 18/18 SignalEngine ✓
|
|
- [x] Architecture tests: 5/5 ✓
|
|
- [x] Integration tests: 47/47 (including 3 E2E pipeline tests) ✓
|
|
- [x] **Total: 87/87 tests passing (0 regressions)**
|
|
|
|
### Database
|
|
- [x] Migrations: 0008_CreateShadowRunTable, 0009_CreateInboxTable, 0010_CreateApprovalQueueTable
|
|
- [x] Schema: JSONB payloads, PIT queries (published_at ≤ cutoff), immutability triggers
|
|
- [x] Idempotency: UNIQUE constraints (outbox_message, approval_queue), dedup by message_id
|
|
- [x] Constraints: Status transitions enforced (Pending → Processed/Failed, Approved → timestamp)
|
|
|
|
### Features Implemented
|
|
1. **Shadow Run Validation** (252+ days)
|
|
- Phase 1: DataBackfill (OHLCV, fees, calendar)
|
|
- Phase 2: Replay (signals → orders → fills)
|
|
- Phase 3: Metrics (Sharpe, PBO, DSR, Calmar, Max DD)
|
|
- Phase 4: Phase Segmentation (Bull/Bear/Sideways/HighVolatility per-phase metrics)
|
|
- Phase 5: Persist (shadow_run table, JSONB analysis)
|
|
- Phase 6: Emit (IOutboxWriter → building_blocks.outbox_message)
|
|
|
|
2. **Async Event Pipeline** (Real-time notifications)
|
|
- OutboxPollerJob: outbox_message → inbox_message (delivery marker)
|
|
- DownstreamConsumerJob: inbox_message → fetch payload → route to consumers
|
|
- Consumers: SignalR (push), ApprovalQueue (gate-conditional), AuditLog (compliance)
|
|
|
|
3. **Market Data Integration**
|
|
- KRX OpenAPI: Real price data (fallback to stub for local dev)
|
|
- Retry logic: Transient (429, 503, 408) vs Permanent (400, 404)
|
|
- Cache: 24 hours per (ticker, date)
|
|
|
|
4. **Approval Workflow**
|
|
- approval_queue table: Pending → Approved/Rejected workflow
|
|
- Constraints: approved_by, approval_reason, rejection_reason validation
|
|
- Audit: requested_at, approved_at, rejected_at timestamps
|

### Validation Gates (CLAUDE.md: "Not Yet Passed")
|
|
|
|
#### 1. **PostgreSQL DbUp Fresh/Upgrade/Re-run/Failure-Recovery Tests** (REQUIRED)
|
|
- [x] Fresh install: DbUp executes 0008, 0009, 0010 in order
|
|
- [x] Upgrade from prior version: No data loss, schema migrations idempotent
|
|
- [x] Re-run: Migrations safe to re-execute (checksums match)
|
|
- [x] Failure recovery: If migration fails, retry doesn't corrupt state
|
|
- [x] **Implementation:** DbUpMigrationTests.cs (14 test scenarios, AGENTS.md v16.0 aligned)
|
|
|
|
#### 2. **Outbox/Inbox Crash-Recovery & Audit Reconciliation** (REQUIRED)
|
|
- [x] Outbox crash: Messages survive process restart, replay-safe
|
|
- [x] Inbox processing: Consumer failures → retry on restart (status=Failed retrieval)
|
|
- [x] Dedup: Duplicate events filtered (UNIQUE(message_id, consumer) constraint)
|
|
- [x] Reconciliation: Evidence of all events processed (correlation_id tracing)
|
|
- [x] **Implementation:** OutboxInboxCrashRecoveryTests.cs (6 scenarios, database-level validation)
|
|
|
|
#### 3. **252+ Trading-Day Shadow Run Execution** (REQUIRED)
|
|
- [ ] End-to-end execution with real market data (2024-2025)
|

|
|
- [ ] DSR (Daily Sharpe Ratio) ≥ 95th percentile validation gate passes
|
|

|
|
- [ ] Phase analysis: Bull/Bear/Sideways metrics non-zero
|
|
- [ ] Audit trail: Every event logged with CorrelationId
|
|
- **Action:** Execute shadow run via ShadowRunJob with real KRX data
|
|
|
|
#### 4. **Manual Activation Workflow** (REQUIRED)
|
|
- [x] Model Card review: Strategy description, risk factors, assumptions
|
|
- [x] Maker-checker approval: Two-person sign-off before live trading
|
|
- [x] Effective date: approval_queue status tracking (Pending → Approved/Rejected)
|
|
- [x] Rollback plan: Rejection workflow documented
|
|
- [x] **Implementation:** 3 endpoints (GetApprovalQueue, ApproveModel, RejectModel) + 6 integration tests
|
|
|
|
#### 5. **Observability & Alerting** (REQUIRED)
|
|
- [x] Batch SLA dashboard: Job completion times, queue depths (IObservabilityService.GetBatchSlaMetricsAsync)
|
|
- [x] Data quality quarantine: Monitor jobs marked `dq` (GetDataQualityMetricsAsync)
|
|
- [x] Duplicate detection: Alert if outbox dedup constraint violated (GetDuplicateDetectionMetricsAsync)
|
|
- [x] Reconciliation breaks: Evidence vs current state mismatch (GetReconciliationMetricsAsync)
|
|
- [x] Model drift: OOS performance tracking vs baseline (GetModelDriftMetricsAsync)
|
|
- [x] **Implementation:** ObservabilityService + GetObservabilityMetrics endpoint + 6 integration tests

## 🚀 Pre-Production Deployment Steps
|
|
|
|
### 1. Database Preparation
|
|
```bash
|
|
# Apply migrations (DbUp handles versioning)
|
|
dotnet run --project src/KArtSell.DbMigrator -c Release
|
|
|
|
# Verify schema
|
|
psql -h 178.104.200.7 -U kartsell -d kartsell -c "\dt model_operations.*"
|
|
```
|
|
|
|
### 2. Shadow Run Rehearsal
|
|
```bash
|
|
# Via HTTP endpoint
|
|
POST /api/shadow-run/initiate
|
|
{
|
|
"modelId": "{uuid}",
|
|
"windowStartDate": "2024-01-02",
|
|
"windowEndDate": "2024-08-31"
|
|
}
|
|
|
|
# Monitor Hangfire dashboard
|
|
# → ShadowRunJob should complete in ~30 minutes (q-research queue)
|
|
# → Check: outbox_message, inbox_message, approval_queue populated
|
|
```
|
|
|
|
### 3. Validation Evidence Collection
|
|
- [ ] PBO evidence: Stored in shadow_run.validation_gates_json
|
|
- [ ] DSR evidence: Daily Sharpe percentile ≥ 0.95
|
|
- [ ] Cost analysis: 2x fee impact documented
|
|
- [ ] Phase breakdown: Bull/Bear/Sideways metrics non-zero
|
|
- [ ] Audit log: All completions (PASS/FAIL) logged
|
|
|
|
### 4. Approval Workflow Execution
|
|
```bash
|
|
# GET /api/approval-queue (list pending)
|
|
# POST /api/approval/{id}/approve (maker-checker sign-off)
|
|
# Verify: approved_at, approved_by populated
|
|
```

## 📋 Risk Mitigation
|
|
|
|
| Risk | Mitigation | Status |
|
|
|------|-----------|--------|
|
|
| **No real data** | Use KRX OpenAPI (fallback stub available) | ✅ Code ready |
|
|
| **Migration failure** | IdUp checksums + rollback procedure | ✅ Designed |
|
|
| **Consumer crash** | Transient retry + idempotency dedup | ✅ Implemented |
|
|
| **Model drift** | OOS monitoring dashboard + alert | ⏳ Needs wiring |
|
|
| **Concurrent access** | DisableConcurrentExecution (60min max) | ✅ Configured |
|
|
| **Data loss** | JSONB immutability + audit triggers | ✅ Enforced |
|

## 🎯 Success Criteria (Pre-Go-Live)
|
|
|
|
### Functional
|
|
- [ ] Shadow run completes in < 30 minutes (with real KRX data)
|
|
- [ ] All 4 validation gates produce numeric results (no NaN, null)
|
|
- [ ] Async events flow: Outbox → Inbox → Consumer (verifiable via logs)
|
|
- [ ] Approval queue auto-populated on gate passage
|
|
- [ ] Audit log entry created for every completion (PASS/FAIL)
|
|
|
|
### Non-Functional
|
|
- [ ] Zero test regressions (87/87 passing)
|
|
- [ ] Query response time: shadow_run SELECT < 100ms
|
|
- [ ] Job concurrency: Single execution held for 60 minutes max
|
|
- [ ] Memory usage: < 500MB per job run
|
|
- [ ] Log compression: Rotate after 10GB per day
|
|
|
|
### Security
|
|
- [ ] No SELECT * (schema-qualified, explicit columns)
|
|
- [ ] No direct module-to-module table access (IOutboxWriter/IInboxStore only)
|
|
- [ ] No sensitive data logged (API keys, PII redacted)
|
|
- [ ] Correlation IDs present in all audit records
|
|

## 📞 Escalation
|
|
|
|
**If any validation gate fails:**
|
|
1. Capture evidence (logs, metrics, database state)
|
|
2. File issue with decision point (e.g., "PBO > 20%, impact assessment needed")
|
|
3. Root cause analysis: Code vs data vs external API
|
|
4. Resolution: Fix + re-run shadow run OR defer with documented exception
|
|
|
|
**Owner:** ModelOperations team
|
|
**Stakeholders:** Risk, Trading, Compliance
|
|

|
|
**Next Actions:**
|
|
1. Execute 252+ trading-day shadow run (this week)
|
|
2. Collect PBO/DSR evidence (evidence_table.md)
|
|
3. Activate maker-checker workflow approval
|
|
4. Go-live authorization
|
|
|
|
**Timeline:** ≤ 2 weeks to production
