(移除過度複雜的統計分析) - ⏰ 補充核心的間隔重複算法實作 (2^成功次數公式) - 🧪 新增延遲計數系統測試規格 (TDD準備) ## API呼叫策略明確化 - 階段1: 完全不呼叫API (純靜態數據) - 階段2: 仍不呼叫API (localStorage持久化) - 階段3: 才開始API呼叫 (有明確的判斷邏輯) - 錯誤降級: API失敗時自動使用靜態數據 ## 後端設計簡化 - 移除複雜的ReviewSessions/ReviewAttempts表設計 - 只保留核心的FlashcardReviews表 (SuccessCount + NextReviewDate) - 簡化Service層，專注間隔重複算法 - 避免過度工程的統計分析功能 ## 技術細節完整性 - ✅ 信心度簡化為3選項 (模糊/一般/熟悉) - ✅ 延遲計數系統測試案例完整 - ✅ 前後端協作邏輯清晰 - ✅ 符合極簡MVP理念 完整的6層文檔架構: 需求/技術/前端/後端/測試/控制 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- note/複習系統/README.md | 26 +- note/複習系統/前端規格.md | 779
