 ## Phase E：规约与提交
 
 - [x] 使用 `trellis-update-spec` 更新现有 `deployment-trialrun.md`，记录候选构建身份的单一来源与远端消费验证职责。
-- [ ] 中文 commit 引用 `08-09-deployment-contract-single-source-harness`。
+- [x] 中文 commit 引用 `08-09-deployment-contract-single-source-harness`（`621934a`）。
 - [x] 不部署、不运行生产 preflight；任务证据明确为 local tooling hardening。
