 ## 階段一：基本流程串接
 - 目標：確保 action 可以被觸發，pipeline 各步驟依序執行，log 出每個主要階段的進入與完成。
 - 驗收：log 中能看到每個階段（如「Step1: pipeline start」、「Step2: findings merge」等）明確訊息，且流程能走完（即使還沒產生 findings）。
-- 完成
+- 已驗收：`code-review` job 的 log 已完整出現 `Step1` 到 `Step8`，並以 `Pipeline 完成` 結束。
 
-## 階段二：Findings 產生與合併
+## 階段二：Git Diff 排除 .gitea/ 資料夾
+- 目標：讀取 Git Diff 時排除 `.gitea/` 資料夾內的所有檔案，避免 AI 分析 workflow 設定等非業務程式碼。
+- 驗收：PR 中有 `.gitea/` 路徑的變更時，diff 內容不包含該路徑的區塊，AI 分析結果不含 `.gitea/` 相關問題。
+- 已驗收：`app/gitea.js` 已在取得 diff 時過濾 `.gitea/` 區塊，且相關單元測試已覆蓋。
+
+## 階段三：Findings 產生與合併
 - 目標：各角色（style/security/performance/maintainability/testing）能產生 findings，並正確合併新舊 findings。
 - 驗收：log 中能看到每個角色 findings 數量、合併後 findings 統計，並有「Step3: merged findings total=...」等訊息。
-- 完成
+- 已驗收：log 已顯示 5 個角色皆有分析結果，並出現 `Step3 merged findings total=13`。
 
-## 階段三：AI 去重與角色確認
+## 階段四：AI 去重與角色確認
 - 目標：嘗試呼叫 LLM 進行 findings 去重與角色確認，API 額度不足時要有降級處理 log。
 - 驗收：log 中能看到 deduplication/resolution confirmation 成功或失敗（如 402），降級時有「保留所有問題」等明確訊息。
-- 完成
+- 已驗收：log 已出現 `AI 去重: 13 -> 11 筆`，且程式具備失敗時保留所有問題的降級處理。
 
-## 階段四：AI 排除問題過濾
+## 階段五：AI 排除問題過濾
 - 目標：讀取排除問題檔案（`.gitea/ai-review/exclusions.json`）進行規則過濾，並呼叫 AI 判斷剩餘問題是否為誤報或不適用，兩層過濾後產生最終問題清單。
 - 驗收：log 中能看到排除問題檔案讀取成功或不存在的訊息、規則過濾數量變化，以及「AI 誤報過濾: N -> M 筆」或降級訊息。
-- 完成
+- 部分驗收：log 已顯示 `讀取排除問題: 50 筆` 與 `排除過濾: 11 -> 0 筆`，但這次未進入 `AI 誤報過濾: N -> M 筆` 的正向路徑。
+- 可驗收紀錄情境：當 `排除過濾` 後仍保留 1 筆以上 findings 時，log 會出現 `AI 誤報過濾: N -> M 筆`；若 API 額度不足或回傳失敗，則會出現 `AI 誤報過濾失敗（...），降級：保留所有問題`。
 
-## 階段五：findings 寫入與 comment 發布
+## 階段六：findings 寫入與 comment 發布
 - 目標：`.gitea/ai-review/findings.json` 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 `.gitea/ai-review/findings.json` 寫入、comment sync 的詳細訊息與順序。
-- 完成
+- 部分驗收：`findings.json` 已成功寫入，也有依序執行舊問題、非嚴重、嚴重 comment 流程；但本次因結果為 0 筆，沒有實際 comment 內容可完整驗證順序。
+- 可驗收紀錄情境：當最終 findings 至少有 1 筆舊問題、1 筆新非嚴重問題或 1 筆新嚴重問題時，log 會分別出現 `舊問題 comment 發布`、`新問題（非嚴重）comment 發布`、`嚴重問題 comment 發布`；其中嚴重問題會逐筆發 comment。
 
-## 階段六：記憶區 commit/push 與錯誤處理
+## 階段七：階段六後驗證 JSON 格式
+- 目標：階段六完成後驗證 `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 `[]`。
+- 驗收：log 中能看到兩個檔案的驗證結果（成功或失敗），格式錯誤時有 AI 修正嘗試與修正後再次驗證的訊息；若檔案不存在，會在驗證完成後看到建立並寫入 `[]` 的訊息；修正失敗時 workflow 狀態為失敗。
+- 已驗收：log 已明確顯示 `.gitea/ai-review/findings.json` 與 `.gitea/ai-review/exclusions.json` 都是 `JSON 格式正確`。
+
+## 階段八：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
+- 已驗收：log 已出現 `persisted findings commit=79506eb push=整理程式碼`，代表 commit/push 成功。
 
-## 階段七：阻擋嚴重問題 PR（第 8 點）
+## 階段九：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
+- 部分驗收：這次 log 顯示 `✅ 無嚴重問題`，因此只驗到正常放行路徑；`exit 1` 的阻擋分支仍需另一次含 critical 的 PR log 驗證。
+- 可驗收紀錄情境：只要 `Step8` 出現 `發現 X 個嚴重問題，workflow 結束（exit 1）`，且 job 以失敗結束，就能驗收這一項；如果該次 PR 的 `filtered` 清單含 `critical`，就應該會看到這段 log。
 
-## 階段八：API Key 輪替
-- 目標：所有平台的 API Key 支援逗號分隔傳入多個，依序嘗試，單一 Key 失敗時自動換下一個，全部失敗則 exit 1。
+## 階段十：API Key 輪替
+- 目標：所有平台的 API Key 支援逗號分隔傳入多個，隨機順序各嘗試一次，單一 Key 失敗時自動換下一個，全部失敗則 exit 1。
 - 驗收：log 中能看到「key[N/M] 失敗」等訊息，換 key 後繼續執行；傳入單一 Key 時行為與原本相同；全部 Key 失敗時 log「所有 API Key 均失敗，終止流程」且 workflow 狀態為失敗。
-- 完成
+- 已驗收：`review.yaml` 已以逗號串接多把 Gemini key，且 `app/llm.js` 與單元測試已覆蓋輪替與失敗退出行為。
 
----
-
-所有階段驗收通過。
+## 階段十一：壓縮 AI 傳入內容減少 token 用量
+- 目標：傳給 AI 的 findings 只保留必要欄位（level、role、location、suggestion）；system prompt 精簡為指令核心；exclusions hint 只傳 location 與 suggestion；AI 回傳後補回原始完整欄位（含 is_new）。
+- 驗收：AI 呼叫的 payload 不含 is_new 等內部欄位，去重與誤報過濾後的 findings 仍保有完整欄位供後續流程使用。
+- 已驗收：`app/findings.js` 已只傳必要欄位給 AI，並在回傳後補回原始 findings 的完整欄位。
