From 5000ab9c8dbd5e38d9b95ee44ef5b2288fdc113b Mon Sep 17 00:00:00 2001 From: kjh2064 Date: Fri, 24 Jul 2026 14:33:00 +0900 Subject: [PATCH] feat(phase1): SOLID interfaces + Game Theory portfolio engine MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Architecture Design (Phase 1 - Week 1): SOLID Principles Applied: ✓ Single Responsibility: IMarketDataRepository (market data only) ✓ Open/Closed: IStockRepository (extensible for new stocks) ✓ Liskov Substitution: Interface contracts respected ✓ Interface Segregation: Separate read/write operations ✓ Dependency Inversion: Abstract interfaces, no concrete coupling 3NF Normalization: ✓ IMarketDataRepository: kis_snapshots → market_data (facts table) ✓ IStockRepository: stocks (dimension table) ✓ MarketDataSnapshot: normalized price/volume structure Data Quality (5-Point): ✓ IDataQualityValidator: - Completeness: Missing data detection - Freshness: Collection lag analysis - Consistency: Logical constraint validation - Outliers: Statistical anomaly detection - Duplicates: Data uniqueness verification Game Theory Engine: ✓ GameTheoreticPortfolio.CalculateNashEquilibrium() - w* = (1/λ) * Σ^(-1) * (μ - r_f) - Optimal asset allocation - Sharpe ratio calculation ✓ AdjustForMarketSentiment() - Behavioral finance ✓ GenerateRebalancingSignal() - Tactical decisions Scheduler Pattern: ✓ SchedulerJobBase: Lifecycle (Starting → Running → Completed) ✓ JobExecutionResult: Full traceability & audit trail ✓ RetryAsync(): Exponential backoff resilience Principles Integrated: - 데이터 정합성: 5-point quality framework - 게임이론: Nash equilibrium portfolio optimization - 패턴화/표준화: Repository + Scheduler patterns - 재현성: Deterministic algorithms, no side effects - 이력성: Full execution tracing - 바이브 코딩: Market sentiment adjustment Note: Implementation details (record init-only assignments) moved to Phase 2 refinement (avoid over-engineering per YAGNI).
