+**完成內容**：
+- 將 production deploy readback 的 `manual_run_button_visible=false`、`gitea_sign_in_required=true`、unauthenticated dispatch `401` 與 `token is required` 投影到 Delivery Workbench summary / `production_deploy` lane metric。
+- 刷新 source readback 觀測 SHA 為 `b754e8a1a46a`；production 仍舊版，CD `#3853` 仍 `Waiting` 且 jobs API `total_count=0`。
+
+**邊界**：只改 committed source / snapshot / API 欄位；未使用 Gitea write API / workflow_dispatch；未讀 token / cookie / session / secret；未操作 host / Docker / K8s / runner service；未使用 GitHub。

-- Delivery Workbench summary 與 `production_deploy` lane metric 現在可直接讀出 `production_deploy_non110_runner_ready=false` 與 registration / service / blocker counts，對齊 CD `#3853` 仍 `Waiting`、jobs API `total_count=0` 的 runner channel blocker。
