合并远端并行的 worker unit 渲染实现

远端 798098e06 与本地 299544719 并行修复了同一问题（deploy 原文安装
unit 覆盖自定义路径）。合并采纳远端实现为准：python3 字面量渲染（含
模板占位路径存在性校验）、install_worker_systemd_units 参数化、Jenkins
双流水线暴露并透传 CONTROLLER/BGFILTER env 参数、guardrails 门禁——
其中流水线透传补上了本地版本刻意未覆盖的传输层缺口。保留本地独有的
readyz 派生修复、connect 重连与冷启动宽限、契约文档收口；删除本地
sed 渲染实现与合并产生的重复参数定义；decision-log 双条目并存。

+## 2026-07-23 生产 API 发布按实际路径渲染 worker systemd unit
+
+- 背景：Server-Provision 支持自定义 current link、API env 和角色 env，并在首次安装时渲染三个 worker unit；API deploy 为下发随 release 更新的 unit 又原样覆盖目标机配置，导致自定义路径在下一次发布时退回模板默认值。
+- 决策：`production-api-deploy.sh` 继续随 release 安装默认命名的 BgFilter、external-generation worker 和 controller unit，但安装前必须用本次部署参数渲染临时文件；新增 `--controller-env-file` 补齐 controller 专属 env 输入。release 内模板保持默认路径，供 provision 和 deploy 共同作为单一模板来源；自定义服务名仍由目标机自行管理，不强制覆盖。
+- 影响范围：`scripts/deploy/production-api-deploy.sh`、`scripts/check-production-api-deploy.mjs`、`jenkins/Jenkinsfile.production-api-deploy`、`jenkins/Jenkinsfile.production-full-build-and-deploy`、`scripts/check-production-ops-guardrails.mjs`、生产运维文档和 worker systemd 发布契约。

+## 生产 API 发布重装 worker unit 不能丢失自定义路径（2026-07-23）
+
+- 现象：Server-Provision 已按自定义 current link 和 env 路径安装 worker systemd unit，但下一次 API 发布后，worker 可能重新读取 `/opt/genarrative/current` 与 `/etc/genarrative/*.env`；默认路径仍有旧 release 时，服务 active 和部署成功都不能证明新二进制已运行。
+- 原因：发布包中的 BgFilter、external-generation worker 和 controller unit 是带默认路径的模板；deploy 若直接 `install` 原文件，会覆盖 provision 已渲染的目标机 unit。external-generation 专属 env 还是可选加载，错误路径可能不会阻止服务进入 active。
+- 处理：API deploy 安装三个 unit 前必须按本次 current、API env 和各角色 env 参数渲染临时文件，安装后保留 release 内原始模板不变；controller 自定义 env 由 `--controller-env-file` 显式传入。API Deploy 与 Full Job 必须同步暴露并透传 controller/BgFilter env，不能让流水线回退默认路径。自定义服务名表示沿用目标机自管 unit，不进入默认 unit 安装分支。
+- 验证：部署 guard 使用临时自定义绝对路径，直接读取实际安装目录中的三个 unit，核对 `WorkingDirectory`、`ExecStart`、共享 API env 与角色 env，不能只用 fake `systemctl is-active` 判绿。
+- 关联：`scripts/deploy/production-api-deploy.sh`、`scripts/check-production-api-deploy.mjs`、`scripts/jenkins-server-provision.sh`、`docs/【开发运维】本地开发验证与生产运维-2026-05-15.md`。
