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). See TECH_DEBT_REGISTER.md for full impact/effort estimates. Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>	2026-08-02 21:09:15 +09:00
