 **已跑驗證**：
 - SigNoz / OTEL / Event Exporter / API config 聚焦回歸：`43 passed`；其中 canonical route migration 為 `9 passed`。ruff、py_compile、四支 shell `bash -n`、canonical route preflight、三份 Kubernetes server dry-run、runner pressure guard、Gitea secret transport guard 與 `git diff --check` 通過。
+- Gitea feature evidence commit `0523af6bfc9572f1822daef7277ace80d79cb1bb` 已由 SSH exact ref 回讀；這只完成 feature 層 durable acknowledgement，main / CD / production / KM writeback 仍是獨立 pending。
 - 先前 route-specific log replay 已驗證 `.120/.121` HTTP `200`、ClickHouse exact marker `1`、15 秒 queue / failure delta `0`；本次三訊號 direct verifier不把該結果誤宣稱成 producer canary。
 - bridge rollback 後 `.120/.121 -> .188:24318` 回 HTTP `200`，legacy cron 已恢復，live user-systemd unit 已移除 / disabled。
