- db.ts：SQLite 連線（better-sqlite3）、WAL 模式、自動 migration - stock-map.ts：台股名稱→代碼映射（2230 檔上市+上櫃） - stock-price.ts：TWSE 即時報價 + FinMind OHLC 歷史資料 - tracker.ts：recordPredictions（LLM 分析後記錄）+ updateTracking（每日判定） - index.ts：分析後自動記錄預測 + 15:00 追蹤更新排程 - Dockerfile：加 build-essential（native 編譯）+ data/ 目錄 - data/tw-stock-list.json：台股代碼映射表（政府開放資料） Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
api.web.finmindtrade.com → api.finmindtrade.com（經實測驗證） Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
設計變更： - 資料記錄與勝敗判定分離，系統只記錄 5 天 OHLC，勝敗查詢時決定 - 移除 realized/expired 狀態，改為 tracking → completed（5天）| superseded - 同股票新預測進來 → 舊的 superseded + next_prediction_id 串聯 - price_snapshots 新增 day_number（有資料的交易日序號） - change_pct_extreme 拆為 change_pct_high + change_pct_low（兩個方向都記錄） - predictions 移除 realized_at/days_to_realize/peak_change_pct，新增 completed_at/next_prediction_id Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- db.ts: 建立 DB 前先 mkdirSync，migrate 成功後才設定全域變數 - stock-price.ts: TWSE/FinMind fetch 加入 AbortSignal.timeout 防止無限等待 - tracker.ts: updateTracking 加入三層 try/catch（DB 開啟、OHLC 查詢、交易寫入） Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
getBasePrice 新增 postTimestamp 參數，根據貼文發佈日期查詢 對應交易日收盤價，而非爬取當下的即時價格。 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
