 - 根因：Next.js 要求 `runtime` 等 route segment config 在当前 route 文件中可被静态解析，不允许从另一 Route Handler 重导出；既有精确合同测试反而固化了非法 re-export，且并发功能本地 production build 未闭环。
 - 修复：在 users route 本文件静态声明 `export const runtime = "nodejs"`，只重导出 DELETE/GET/PATCH/POST/PUT handlers；不复制 handler、不修改权限或客户数据逻辑。合同测试改为强制本地 runtime 常量并拒绝 runtime re-export。

+## BUG-134 | staging admin origin selector 未配置导致 exact-SHA 自动部署失败
+
+- 状态：investigating
+- 首次发现：2026-08-06
+- 最近更新：2026-08-06
+- 影响面：staging `.env.staging` 的公开 identity selector、自动 deploy run `1502`；应用容器、业务数据库和 production 未被修改。
+- 用户现象：staging gate `1500` 已成功验证并发布 SHA `9a3d0d440f43deab66c1f8a4a08cdbfc6f9d73eb` 的 immutable artifact，但自动 deploy `1502` 在远端 env 校验时报 `invalid staging selector: ADMIN_USER_ORIGIN` 并 fail closed；公网继续健康运行旧 SHA `e59f15d352787f3d05425ba8c459d092e9801a20`。
+- 触发条件：包含双 host self-hosted identity validator 的 controller 部署到现有 staging host，而 `.env.staging` 尚未包含精确且唯一的 `ADMIN_USER_ORIGIN=https://admin.staging.jyotisha.chat`。
+- 根因：并发 admin rollout 将 admin host origin 加入应用和 validator 合同，但 staging host-managed env 未在发布前同步新增的非密钥 selector；quality gate 验证仓库合同，不读取主机 secret/env，因此直到 mutation 前远端校验才暴露漂移。
+- 修复：待在共享 staging mutation lock 下，仅向原文件原子补入公开 `ADMIN_USER_ORIGIN` selector，保留全部既有内容、`deploy:deploy` owner 和 `0600` mode；不得输出、复制或重写其他 secret 值。随后用 exact-SHA gate artifact 重新部署。
+- 验证：脱敏只读检查已确认 `.env.staging` 为 `deploy:deploy 0600`、`AUTH_USER_ORIGIN` 精确且唯一、`ADMIN_USER_ORIGIN` 计数为 0；待 selector validator、最新 staging gate、exact-SHA deploy、公网/host SHA、容器 restart、日志和未登录边界验收。
+- 防复发：任何新增 staging host-managed selector 必须在同一 rollout runbook 中包含 deploy 前 presence/exact-value 检查；quality gate 成功不能替代 host env validation。env 修复必须共享 mutation lock、原子替换并保持 owner/mode，严禁打印 raw env。

 Prevention: both validate and publish exact-SHA checkouts use three bounded 300-second attempts, a 15-second connect timeout, and a 60-second/1-B/s stalled-transfer threshold.

+## ERR-097 | Staging host env missed the reviewed admin-origin selector | investigating 2026-08-06
+
+Staging gate `1500` successfully validated and published the exact SHA, but automatic deploy `1502` stopped before app mutation with `invalid staging selector: ADMIN_USER_ORIGIN`. A redacted read-only check confirmed `.env.staging` remained `deploy:deploy 0600`, had one exact user origin, and had zero admin-origin definitions. Public staging therefore remained on the prior healthy SHA; this was not a migration failure and production was not involved.
+
+Prevention: when a reviewed identity rollout adds a host-managed non-secret selector, update the staging env under the shared mutation lock before deploying the dependent controller. Modify only the named public selector through a mode-`0600` atomic replacement that preserves deployment-tree UID/GID; never print or copy the raw env. Re-run the exact validator and require the same gate-attested SHA in `main`, `staging`, host state, and public health before closure.
