 ## 階段五：findings 寫入與 comment 發布
 - 目標：findings.jsonl 正確寫入，comment 發布順序正確（舊問題→非嚴重→嚴重），每步有 log。
 - 驗收：log 中能看到 findings 寫入、comment sync 的詳細訊息與順序。
-- 完成
 
 ## 階段六：記憶區 commit/push 與錯誤處理
 - 目標：記憶區能成功 commit/push，錯誤時有明確 log，流程結束有總結訊息。
 - 驗收：log 有「persisted findings」、「commit=...」、「push=...」等訊息，錯誤時有「Runner failed: ...」等明確錯誤說明。
-- 完成
 
 ## 階段七：阻擋嚴重問題 PR（第 8 點）
 - 目標：如果 PR 問題表格中有嚴重（critical）問題，workflow 需直接 exit 1，不讓流程成功。
 - 驗收：log 中能看到「critical 問題存在，workflow 結束（exit 1）」等明確訊息，且 workflow 狀態為失敗。
-- 完成
 
 ---
 
-所有階段驗收通過。
+每個階段都會加上明確的 log，並確保即使部分功能未完成也能降級執行、不會中斷 pipeline。
+
+每次執行後請貼 log，我會協助 debug。
