Each reference job runs `pnpm run check:ci` without any shard selector. `DSH_GATE_CONCURRENCY=1` makes the top-level aggregate execute one ready gate at a time; coverage, snapshot replay, built-bin smoke, and publication validation also receive worker counts of one. The reference jobs may run beside one another, but each host's repository gates are serial and complete.

## Problem
The three required Linux worker jobs in [CI](../../../../.github/workflows/ci.yml) (`node 24 / static`, `node 24 / coverage`, `node 24 / snapshots and artifacts`) run on the hosted enterprise 32-core pools; the required verdict job that aggregates them (`all checks passed`) runs on standard `ubuntu-latest`. When the enterprise pools degrade — jobs queue indefinitely or the enterprise labels vanish — every open pull request becomes unmergeable, and the ordinary recovery of merging a fix is itself deadlocked behind the very required checks that cannot run. **Scope: this switch recovers an enterprise Linux-pool outage.** The verdict's other required dependencies (`node-compat`, `python-sdk`, `windows`) stay on standard hosted runners by design (the portable boundary); in a broader GitHub-hosted capacity failure that also takes out the standard pools, those dependencies still block `all checks passed`, and only the Windows leg has no in-house substitute at all — during the 2026-07-27 outage the standard pools recovered first, which is the ordering this design bets on. An outage therefore needs a switch any responder with repository write access can throw without merging anything.

When the enterprise pools degrade — jobs queue indefinitely or the enterprise labels vanish — every open pull request becomes unmergeable, and the ordinary recovery of merging a fix is itself deadlocked behind the very required checks that cannot run. **Scope: this switch recovers an enterprise Linux-pool outage AND a hosted Windows-pool outage.** The verdict's other required dependencies (`node-compat`, `python-sdk`, `windows`) stay on standard hosted runners by design (the portable boundary); in a broader GitHub-hosted capacity failure that also takes out the standard pools, those dependencies still block `all checks passed`. An outage therefore needs a switch any responder with repository write access can throw without merging anything.
## Decision
Each of the three required Linux worker jobs and the `all checks passed` verdict job, which would otherwise stay queued on the failed pool even after every worker passed — resolves its runner pool through the `DSH_CI_FAILOVER` repository variable. Unset (normal), they run on the hosted enterprise pools. Set to `selfhosted` by any repository writer, all four retarget onto the in-house self-hosted `vm-backup` pool, coverage and snapshot concurrency drop to shared-VM bounds, and the hosted-path pnpm cache restores are skipped. The switch is writer-manageable repository state, not a merge, so it works while every check is red. The in-house pool's readiness is continuously re-proven by the `serial / linux (self-hosted standby)` lane, which runs the complete unsharded aggregate on every master push.

Unset (normal), they run on the hosted enterprise pools. Set to `selfhosted` by any repository writer, all five retarget onto the in-house self-hosted pools: the Linux jobs and verdict onto the `vm-backup` pool, coverage and snapshot concurrency drop to shared-VM bounds, and the hosted-path pnpm cache restores are skipped; the native Windows job onto the `dsh-win-ci` pool. The switch is writer-manageable repository state, not a merge, so it works while every check is red. The in-house pools' readiness is continuously re-proven by the `serial / linux (self-hosted standby)` and `serial / windows (self-hosted standby)` lanes, which run the complete unsharded aggregates on every master push.
### What the in-house pool is
`vm-backup`: one 64-core VM, six always-on systemd-managed runner instances. Its image must preinstall Playwright Chromium's Linux system packages; CI downloads the lockfile-selected browser but never runs `apt` on this persistent shared host. Check the latest `serial / linux (self-hosted standby)` run before switching: its aggregate includes browser replay, so a green standby verifies both ordinary capacity and this browser prerequisite.
#### Windows pool
`dsh-win-ci`: 32 always-on runner instances (scheduled tasks `GH-Runner-01``GH-Runner-32`) on the in-house Windows CI server (one 96-core / 580 GB machine). Labels: `[self-hosted, dsh-win-ci, windows]`. The image must preinstall Node 24, pnpm, Git (with Git Bash on `PATH`, i.e. `C:\Program Files\Git\bin` — the `bash` tool spawns `bash` by name), PowerShell 7, and enable Developer Mode for symlink support. Check the latest `serial / windows (self-hosted standby)` run before switching: a green standby verifies the pool can execute `check:ci:windows-complete` end-to-end.
### Switch (any repository writer, ~1 minute, no merge)
1. Repository **Settings → Secrets and variables → Actions → Variables → New repository variable**: name `DSH_CI_FAILOVER`, value `selfhosted`.
2. Retrigger the required jobs so they re-resolve their pool. Jobs already **queued** for the hosted labels do not retarget and cannot be re-run in place, so for the documented indefinite-queue outage, cancel the stuck run and re-run all jobs, or push a new commit; "Re-run failed jobs" only helps once a job has actually failed rather than queued.
3. That is the entire switch. Under failover the workflow also, automatically: drops `DSH_COVERAGE_MAX_WORKERS` to 8 and `DSH_SNAPSHOT_MAX_CONCURRENCY` to 12 (sized for six always-on instances: worst case 6 × 8 = 48 coverage workers on the 64-core VM) (shared-VM contention bounds), and skips the hosted-path pnpm cache restores (the VM's persistent store serves warm installs).
#**Dependabot exception.** All four selectors deliberately exclude `dependabot[bot]`: under failover, Dependabot PRs stay queued for the hosted pool rather than executing dependency-supplied code on the persistent VM. A Dependabot PR that remains queued during an outage is expected behavior, not a failed switch; it completes when the hosted pool recovers.

**Who can flip the variable.** GitHub's API lets any collaborator with write access manage repository variables, so the switch is writer-level, not strictly admin-only. In this repository's trust model that is not an escalation: the runner group admits all workflows of this private, fork-disabled repository (a deliberate trade to make PR-ref failover possible at all), so any writer could already reach the VM by pushing a branch workflow. The boundary against untrusted code is repository membership; the variable only routes work for members.

## 决策

三个必需的 Linux 工作作业、独立的原生 Windows 作业,以及 `all checks passed` 判定作业(若不随切换,即使全部工作作业通过,它仍会滞留在故障池的队列中)——各自通过仓库变量 `DSH_CI_FAILOVER` 解析运行器池。变量不存在(正常)时它们运行在托管企业池上;由任何具备写权限的协作者设为 `selfhosted` 时,五个作业全部切换到公司自有的自托管Linux 作业与判定作业切到 `vm-backup` 池,覆盖率与快照的并发降到共享虚拟机上限,并跳过托管路径的 pnpm 缓存恢复;原生 Windows 作业切到 `dsh-win-ci`。这个开关是写者可管理的仓库状态而非一次合并,因此在所有检查都是红色时仍然有效。自有池的就绪状态由 `serial / linux (self-hosted standby)``serial / windows (self-hosted standby)` 通道持续验证——每次 master 推送都在其上运行完整的未分片聚合流程。
### 自有池是什么
`vm-backup`:一台 64 核虚拟机6 个常驻 systemd 管理的运行器实例。其镜像必须预装 Playwright Chromium 的 Linux 系统软件包CI 会下载锁文件选定的浏览器,但绝不在这台持久化共享主机上运行 `apt`。切换前先看 `serial / linux (self-hosted standby)` 最近一次运行:其聚合流程包含浏览器回放,因此绿色热备同时验证常规容量和这项浏览器先决条件。
#### Windows 池
`dsh-win-ci`:公司内部 Windows CI 服务器(一台 96 核 / 580 GB 机器)上 32 个常驻运行器实例(计划任务 `GH-Runner-01``GH-Runner-32`)。标签:`[self-hosted, dsh-win-ci, windows]`。镜像必须预装 Node 24、pnpm、GitGit Bash 在 `PATH` 上,即 `C:\Program Files\Git\bin`——`bash` 工具按名称 spawn `bash`、PowerShell 7并为符号链接支持启用开发人员模式。切换前先看 `serial / windows (self-hosted standby)` 最近一次运行:绿色热备验证该池能端到端执行 `check:ci:windows-complete`
### 切换步骤(任何具备写权限的协作者,约 1 分钟,无需合并)
1. 仓库 **Settings → Secrets and variables → Actions → Variables → New repository variable**:名称 `DSH_CI_FAILOVER`,值 `selfhosted`
2. 重新触发必需作业,使其重新解析运行器池。已经为托管标签**排队**的作业不会重定向,也无法原地 re-run因此对于本手册所述的无限排队故障应取消卡住的运行并 re-run all jobs或推送一个新提交“Re-run failed jobs”只有在作业真正失败而非仍在排队时才有用。
3. 切换到此完成。故障切换状态下工作流还会自动:把 `DSH_COVERAGE_MAX_WORKERS` 降为 8、`DSH_SNAPSHOT_MAX_CONCURRENCY` 降为 12按 6 个常驻实例定容最坏情况下6 × 8 = 48 个覆盖率工作进程运行在 64 核虚拟机上)(共享虚拟机的争抢上限),并跳过托管路径的 pnpm 缓存恢复(虚拟机的持久 store 直接提供热安装)。
#**Dependabot 例外。**个选择器都刻意排除了 `dependabot[bot]`故障切换期间Dependabot 拉取请求继续在托管池排队,而不是把依赖项提供的代码放到持久化虚拟机上执行。故障期间 Dependabot PR 持续排队是预期行为而非切换失败;托管池恢复后它会自行完成。

**谁能扳动这个变量。**GitHub 的 API 允许任何具有写权限的协作者管理仓库变量因此该开关实际是写者级而非严格的管理员级。在本仓库的信任模型下这并不构成升权runner group 接纳本私有、禁 fork 仓库的全部工作流(这是让 PR 引用的故障切换得以成立的刻意取舍),因此任何写者本就可以通过推送分支工作流触达这台虚拟机。抵御不可信代码的边界是仓库成员资格;变量只是为成员路由工作。
