 判讀：這輪修的是「治理事件資料落地」而不是畫面格式。AI 自動化要能閉環，scanner / governance / AWOOOP 必須先能完整記錄事實；否則前端再漂亮也只是看不到真相的控制台。

+
+## 2026-05-07（台北）— AwoooP Run Timeline 出站訊息語義化
+
+**背景**：
+
+- AwoooP Run Detail 目前能鏡像 Telegram 出站訊息，但 timeline title 仍顯示：
+  - `telegram 出站：approval_request`
+  - `telegram 出站：final`
+  - `telegram 出站：error`
+- 對 SRE 來說，這無法快速區分「AI 自動修復完成」、「AI 自動修復失敗轉人工」、「Runbook 待審核」、「AI 治理警報」或「告警審批卡」。
+
+**改動**：
+
+- `platform_operator_service.py` 新增 `_outbound_timeline_title()`。
+- 不改 DB schema，不新增 message_type enum，避免再引入 migration 風險。
+- 保留原始 `message_type` 到 timeline metadata，畫面顯示改為人能判斷的語義標題：
+  - `TELEGRAM：Runbook 待人工審核`
+  - `TELEGRAM：AI 治理警報`
+  - `TELEGRAM：AI 自動修復失敗，已轉人工`
+  - `TELEGRAM：AI 自動修復完成`
+  - `TELEGRAM：告警審批卡`
+  - `TELEGRAM：漸進式狀態回饋`
+- 新增 `test_awooop_operator_timeline_labels.py` 回歸測試。
+
+**驗證**：
