 8. 階段七驗證來源分支中的 `findings.json` 與 `exclusions.json` 是否為合法 JSON 格式，格式錯誤時先嘗試透過 AI 修正內容，再重新驗證；修正後仍不合法才 exit 1；之後才檢查檔案是否存在，不存在則建立並寫入 `[]`
 9. 傳給 AI 的 findings 只保留必要欄位（level、role、location、suggestion），排除 `is_new` 等內部欄位；system prompt 精簡為指令核心；exclusions hint 只傳 location 與 suggestion，減少 token 用量
 10. 執行時會額外記錄來源分支狀態、`findings.json` / `exclusions.json` 的檔案路徑、大小、mtime 與 raw/normalized 筆數，方便追查讀檔與分支內容不一致的問題
