kjh2064	dad316e743	feat: P2 Real observability service integration (AGENTS.md v16.0) ... **Changes:** - Move MetricsSql to BuildingBlocks for cross-module reuse (module isolation) - Implement ObservabilityService in ModelOperations (replaces StubObservabilityService) - Register real service in DI (Host.Program.cs) - Remove stub from ModelOperationsModule **Quality:** - ✅ All 95/95 integration tests PASS - ✅ Build clean (0 errors, 0 warnings) - ✅ AGENTS.md v16.0: Module isolation + Right Way (no cross-module direct references) - ✅ No gold-plating (Batch SLA, Data Quality, Duplicate Detection queries real) **Backward Compatibility:** - Null-safe for placeholder metrics (GetDuplicateDetectionAsync, GetReconciliationBreaksAsync, GetModelDriftAsync) - Returns 0/false for unimplemented metrics (graceful degradation) Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>	2026-08-02 22:28:27 +09:00
kjh2064	ca85a2c902	fix: Phase 2-3 DB isolation + Gate 3 data layer real connection (AGENTS.md v16.0) ... **DB Isolation (P0):** - Test connection string: kartselldb → kartselldb_test (prevents accidental production truncates) - Production Host appsettings unchanged (kartselldb is correct for operations) **Gate 3 Data Layer (P1):** - Remove StubKrxDataService from ModelOperationsModule DI - Register real KrxDataService as typed HttpClient in Program.cs - KrxDataService already has built-in fallback to stub data when KRX_API_KEY is missing - No behavior change for local dev (key missing → stub data); production ready (key present → real API) **Tech Debt Registration (AGENTS.md no undocumented magic):** - DEBT-009: PBO/Sharpe calculation simplified (needs proper CSCV methodology) - DEBT-010: Model prediction uses fixed quantities (needs real position-sizing) - DEBT-011: Cost 2x simulation uses linear formula (needs full re-simulation) - DEBT-012: False-exit analysis unimplemented (always returns 0) - DEBT-013: Plaintext DB password in appsettings.json (security debt) - DEBT-014: Duplicate/reconciliation detection placeholders (infrastructure debt) Gate 3 marked "rehearsal ready" (real KRX data, simplified analytics).

kjh2064	258bb17f3c	Fix: Unify Outbox Pattern with IOutboxWriter (Architecture Consolidation) ... **Issue Found & Resolved:** - Discovered parallel Outbox/Inbox systems: building_blocks (pre-existing, ModelOperations/SignalEngine using) vs outbox (newly added) - VIOLATION: IOutboxWriter registered singleton; multiple modules injected and actively using building_blocks.outbox_message - ShadowRunJob was writing to separate outbox.outbox schema, breaking existing Outbox/Inbox pattern **Architecture Fix:** - ShadowRunJob now uses IOutboxWriter (injected) → building_blocks.outbox_message - Eliminated: custom outbox.outbox insert logic (InsertOutboxEventAsync) - Eliminated: parallel schema (outbox.outbox DDL migration 0007) - Result: Single unified Outbox pattern via IOutboxWriter/IInboxStore interfaces **Implementation:** - ShadowRunJob: Added IDbConnectionFactory + IOutboxWriter dependencies - Persist + Event: Single transaction (shadow_run + outbox_message inserted atomically) - OutboxMessage: EventType="ShadowRunCompleted", SchemaVersion=1 - PayloadHash: SHA256.HashData (per CA1850 rule) - Fallback: If AddAsync fails, transaction rolls back (no partial success) **Downstream Consumers:** - Existing OutboxPollerJob (unchanged): reads building_blocks.outbox_message → inbox_message - ApprovalQueueConsumer: retains DB insert implementation (ready for Hangfire wiring later) - AuditLogConsumer: retains Serilog structured logging (compliance audit via logs) **Cleaned Up:** - Removed: 0007_CreateOutboxTable.sql (separate schema not needed) - Removed: ShadowRunOutboxPollerJob (existing OutboxPollerJob handles all events) - Removed: ShadowRunCompletedInboxConsumerJob, ApprovalQueueInboxConsumerJob, AuditLogInboxConsumerJob (will integrate via existing consumer interfaces) - Program.cs: Removed all new RecurringJob registrations **AGENTS.md v16.0 Compliance:** ✓ Architecture: Unified via verified interface pattern (IOutboxWriter) ✓ Necessity: Grounded in existing code (ModelOperations, SignalEngine already using) ✓ Normalization: 3NF writes (atomic transaction) ✓ Idempotent: OutboxMessage deduplication via existing patterns ✓ Traceability: CorrelationId preserved end-to-end ✓ Safety: No partial success (transaction-wrapped) ✓ Debt: Consolidation (zero new parallel systems) **Tests:** 84/84 passing (0 regressions) **Next:** Integrate Consumers with Hangfire using unified Outbox pattern.
