## 1. 目的

Nginx public gateway 是公開網站、API、Webhook、WebSocket、TLS、ACME 與 AI provider proxy 的共同入口。若 live Nginx conf 被手動或緊急變更，IwoooS 不能只看 route `200`、Nginx active、dashboard up、CD success 或 UI 可見就判定事故已驗收。

本文件補上事故後回讀計畫：未來若發生 gateway / Nginx 變更或事故，必須用脫敏 evidence ref 回填 actor、時間窗、變更意圖或 break-glass、改前改後 route 狀態、source-to-live diff、`nginx -t` readback、reload / no-reload 判定、route smoke、TLS / ACME、WebSocket、upstream、AI provider、monitoring、跨專案同步、回滾、防再發與 no-false-green attestation。

這個計畫不是 live conf received、不是 rendered diff accepted、不是 `nginx -t` 授權、不是 Nginx reload、不是 route smoke、不是 DNS / TLS probe、不是 certbot renew、不是 host write，也不是 production write 或 runtime gate。
