 【已完成】
+   - V10.217 讓 `/observability/ppt_audit_history` 的 AiderHeal 派工改為非阻塞背景任務：頁面立即回「已排入」，修復工作在背景執行，避免瀏覽器與 Gunicorn worker 等 SSH、模型與 git push 到超時。
    - V10.216 修正 `/observability/ppt_audit_history` 的 AiderHeal 派工斷點：失敗簡報即使只有 `issues_found` 診斷摘要也能一鍵送修，並修正 `execute_code_fix` 參數與 dict 回傳解析，避免按鈕 400/500。
    - V10.215 強化 `/observability/ppt_audit_history` 視覺問題追蹤：將 `issues_found` 拆成投影片、問題類型、問題文字與回放入口，新增「視覺問題追蹤」面板，讓問題簡報能直接定位與預覽。
    - V10.213 補 `/observability/ppt_audit_history` 視覺 QA 診斷摘要：審核歷史與 Action Queue 直接顯示 `ppt_audit_results.issues_found` 的投影片問題，讓「有問題」可追查，不再只剩問題數或空白錯誤欄。
