Problem
The required pull-request Windows verdict needs a fast win32 toolchain signal without making the aggregate wait for scarce Windows capacity. Wine provides that critical-path signal but runs over a Linux kernel and case-sensitive ext4, uses a hoisted dependency layout, and cannot prove NTFS, DACL, ConPTY, crash durability, or native process behavior. With the native serial references disabled, every pull-request head also needs an automatic real Windows-kernel result.
A coverage audit found that stale branch state had restored temporary exclusions for supported LSP sources. Native Windows therefore needed to execute the complete supported source inventory at the same 100%-per-file threshold instead of relying on a smaller platform-specific denominator.
Decision
The required windows job in ci.yml remains windows node 24 / wine blocking on ubuntu-latest. It retains the checksum-verified Windows Node, Wine apt and pnpm caches, a hoisted install confined to a workspace snapshot, and the shared Wine gate script that runs the workspace build and production site. Node distribution transfers use bounded retries; when nodejs.org stalls on the large archive, a range-capable transport mirror resumes the same bytes, but nodejs.org remains the version and SHA-256 authority and the archive is never promoted before that checksum passes. The stable windows job id remains a dependency of all checks passed. The archived Wine experiment preserves its measured trade-offs, while this note owns the current dual topology.
Every pull request also starts an ordinary independent windows-native job named windows node 24 / native complete on the organization-owned dsh-windows-2025-16core runner. It enables Developer Mode for workspace symlinks, provisions the repository-pinned @pnpm/exe through pnpm/action-setup standalone mode, performs an immutable install without a transferred store archive, and runs pnpm run check:ci:windows-complete under native PowerShell. Package scripts therefore expose pnpm.exe through npm_execpath, making the complete inventory exercise shell-free package-manager re-entry on Windows. A 120-minute timeout bounds a stuck gate without treating the measured performance target as a correctness deadline.
The native job is deliberately absent from all-checks-passed.needs and does not use continue-on-error: the aggregate neither waits for it nor changes conclusion because of it, while the job retains its own unmasked result. Workspace build, production-site, and 100%-per-file coverage failures make the native job fail. Static, documentation, package, built-artifact, lint, and snapshot inventories run in the same job as observational gates: their failures remain visible without changing the native aggregate result because Linux owns their blocking verdict.
The 16-core lane admits four concurrent outer gates. Workspace build, production-site validation, and instrumented coverage start immediately. Exempt-heavy coverage waits for the build to pass, so its temporary Oxlint contract probes cannot race source compilation. Every observational gate waits for both coverage gates to settle, regardless of outcome, before entering an available slot; its own needs edges still require their predecessors to pass. This also keeps later static gates that create temporary contract files from racing either coverage scan. In-job partitioned coverage uses eight single-worker shards, while the exempt-heavy gate receives two workers from DSH_COVERAGE_MAX_WORKERS=6. The initial phase therefore has about ten active execution units; after build, starting exempt-heavy while build leaves keeps the peak near eleven when site and instrumented coverage are still running. publint is capped at eight workers when the observational inventory starts. Every Vitest project uses forked workers because Node 24's CJS lexer fatal reproduced in shared worker threads on Windows and POSIX. Both coverage gates set Vitest's default per-test and polling budgets to 30 seconds because unrelated process, Git, SQLite, watcher, grammar, and static-gate fixtures can exceed 15 seconds only under the complete lane's concurrent Windows instrumentation. The script-only translation-pairing merge suite runs in the exempt-heavy gate because it imports only scripts/ sources and child processes; V8 instrumentation contributes no threshold coverage there but magnifies Git-process latency. Lefthook concurrency fixtures retain their outcomes with 30-second case budgets and a 10-second process-ready probe, while the installer allows five seconds for a preempted lock owner to publish its record after exclusive creation. Directory-picker composition gives its debounced config write an explicit 15-second poll budget; workspace-context composition fixtures use a test-owned signal without an unrelated one-second deadline. These lane-scoped budgets preserve asserted outcomes, while the 120-minute job deadline still bounds a stuck run. The LSP sources and the ACL-sandbox sources remain in the Windows denominator: stub-based failure-path suites carry every in-process ACL-sandbox file to 100%, and only the runner entry stays excluded — it executes exclusively as a spawned child outside the instrumented run, its behavior pinned end-to-end by the runner suite. Narrow annotated V8 ignores cover only unreachable branches (peer-platform arms and lifecycle-unreachable guards), with their behavior tests retained on the owning platform.
The 16-core allocation is the measured capacity point for this inventory. Six-worker coverage trials produced complete passes in 6 minutes 27 seconds and 7 minutes 50 seconds, while exact-head trials with four, three, and two concurrent workers inside one instrumented Vitest process exposed unreliable fixtures and worker exits. Separate single-worker child processes retain process isolation. Sixteen-shard samples reduced instrumented coverage to 112.66–122.01 seconds, but used the whole host before the exempt, build, and site work was counted; eight shards deliberately trade some latency for headroom. A 32-core comparison reduced aggregate gate time by only 1.47 seconds and still triggered the CJS-lexer fatal inside a fork worker, so additional cores did not provide a reliable wall-clock improvement.
The first native run exposed two failures hidden by the compatibility lane. Documentation projection tests derived an image basename by splitting only on /; they now use Node's platform basename. Chokidar consumers received %TEMP% through the C:\\Users\\RUNNER~1 8.3 alias while libuv returned the long directory name, tripping its Windows event-path assertion. Shared settings and credentials watchers, plus Cordis module and exact-config HMR, now canonicalize the existing native watch base or deepest existing ancestor before opening the watcher and preserve a missing suffix, while file access and diagnostics retain the configured path. Module HMR attaches listeners and awaits the main watcher's ready event before plugin startup settles, so an immediate post-boot edit cannot race the initial scan. HMR acceptance derives expected identities through the same asynchronous native realpath operation, avoiding a synchronous Windows spelling that can retain the 8.3 alias.
Portable filesystem fixtures derive paths with node:path, compare native realpath identities, preserve file URLs at Node launcher boundaries, normalize only API-owned separators or line endings, and use filenames legal on every host. POSIX-only signal, mode-bit, unreadability, and writer-lock cases are platform-gated; portable failure contracts instead assert structured error codes, rollback, last-good state, atomic replacement, and absence of temporary residue through conflicts available on every host. Credentials permission validation uses an invalid-path fixture whose pre-lookup ERR_INVALID_ARG_VALUE is non-absence on every host, rather than depending on whether a file ancestor produces ENOTDIR or ENOENT. Worker-death fixtures drive real termination from the host after observing their protocol preconditions instead of calling process.exit() inside a nested Windows Worker; this preserves the worker-exit contract without exposing the enclosing Vitest fork to Node's process-wide native exit assertion. Stress and integration workloads keep their original assertions and receive explicit bounded time budgets where Windows instrumentation or process teardown can exceed Vitest's default ceiling.
Native watchers use canonicalizeWatchPath() to realpath the deepest existing ancestor, prove it is an enumerable directory when a suffix is missing, and restore that suffix. This prevents Windows 8.3 aliases from being mixed with long-form libuv events and preserves ENOTDIR for a regular-file ancestor on every host. Settings, credentials, skill roots, and Cordis HMR retain configured paths for discovery and diagnostics; module HMR uses the canonical spelling for Node's load-cache identity, attaches listeners, and awaits its main watcher before plugin startup settles, so an immediate post-boot edit cannot race the initial scan. A skill root that is itself a symbolic link remains unexpanded when watchFollowSymlinks: false, allowing Chokidar to enforce that boundary.
Windows durable JSONL paths keep drive roots in native spelling and apply the extended-length namespace only to descendants and staging paths. The ACP teardown ladder uses real Node children, proves graceful and forced tiers with host-appropriate outcomes, and avoids claiming POSIX signal delivery on Windows. Executable fixtures provide .cmd shims and PATHEXT where the product accepts a bare command. Repository-cache helpers live inside the selected Git subpath so their declared file: dependencies expose command shims identically on Windows. The bundled installer exports pnpm's own workspace-ignore configuration, retains PNPM_HOME for pnpm data while removing that directory from lifecycle PATH, and prioritizes .CMD in PATHEXT; nested Git-package installation therefore cannot rejoin the enclosing workspace or let an inherited Windows pnpm executable outrank the transaction-owned wrapper.
Post-boot profile watcher setup proceeds only while the root fiber and Loader are both live. A concurrent setup error is contained only when the same invocation's recorded signal already owns shutdown; unrelated HMR failures remain loud. The process-shutdown controller lets a successful one-shot completion drain Node's remaining handles after root disposal, while teardown failure, deadline, and signal escalation retain forced exit. The vendored Include serializes debounced writes, retries only transient access or busy failures with bounded backoff, and observes every timer rejection. A terminal persistence failure remains on the queue and is rethrown to the teardown owner, while successful teardown drains the latest write.
Shiki disables lazy TextMate-regex compilation and warms each boot grammar before user content enters the unchanged per-line tokenization budget, so scheduler contention cannot publish a partial highlighted stream. The Codex real-product fixture is pinned to stable 0.147.0 schemas and selects an actually advertised command tool and argument shape, preserving the provider-owned protocol while proving unattended rejection and whole-tree exit on each host.
Alternatives considered
Make native Windows a dependency of all checks passed. This gives the aggregate the highest-fidelity Windows verdict, but makes every merge wait for the slowest hosted job and for Windows capacity. The independent result keeps the signal automatic without changing the existing required path.
Run only Wine on pull requests. Wine reaches blocking win32 toolchain branches quickly, but can report green while a real NT, NTFS, PowerShell, process, or addon contract is broken.
Mark the native job continue-on-error. That would make its check appear successful after a gate failure. Keeping an ordinary independent job preserves the diagnostic conclusion; omission from aggregate needs is the only non-blocking mechanism.
Exclude unsupported-looking files or weaken Windows fixtures. Rejected because the affected LSP, watcher, persistence, client, and process behavior is supported. Peer-platform branches are marked narrowly; portable outcomes stay in the denominator and are exercised through host-realistic fixtures.
Keep GitHub's standard windows-2025 runner. That portable two-core image completed the exact inventory reliably, but its 32-minute serial result made the automatic native signal substantially less useful than the selected 16-core runner.
Use a 32-core or larger runner. The 32-core comparison improved aggregate gate time by only 1.47 seconds over 16 cores and failed in Node's CJS lexer; earlier high-concurrency 32-core and 64-core trials failed in the same class. More capacity therefore added allocation cost without a stable end-to-end gain.
Consequences
Wine preserves the required aggregate's existing critical path and job identity. Native Windows can still be pending or red when all checks passed turns green, so branch protection consumes Wine while reviewers and follow-up automation consume the separate native result.
Every pull request nevertheless receives a real NT kernel, NTFS, PowerShell, Windows process, native addon, and supported-source coverage signal. The native job duplicates setup and the two blocking builds and is materially slower on the standard image, but it also exposes path, watcher, lifecycle, and fixture defects hidden by the compatibility lane.
Maintainers must preserve two intentional execution topologies: the Wine snapshot uses Linux installation plus a hoisted layout to reach win32 binaries, while the native job uses the immutable workspace on the organization-owned 16-core Windows runner. A failure unique to either job must be classified against that boundary rather than weakened or silently skipped.

问题
拉取请求必需的 Windows 判定既需要快速的 win32 工具链信号，也不能让聚合流程等待稀缺的 Windows 容量。Wine 提供这项关键路径信号，但它运行在 Linux 内核与区分大小写的 ext4 之上，采用 hoisted 依赖布局，且无法证明 NTFS、DACL、ConPTY、崩溃持久性或原生进程行为。原生串行参考流程停用期间，每个拉取请求分支头还需要自动取得真实 Windows 内核结果。
覆盖率审计发现，陈旧分支状态恢复了针对受支持 LSP 源码的临时排除项。因此，原生 Windows 需要按同一逐文件 100% 阈值执行完整的受支持源码清单，而不能依赖缩小后的平台专用分母。
决策
ci.yml 中必需的 windows 作业仍是在 ubuntu-latest 上运行的 windows node 24 / wine blocking。它保留经过校验和验证的 Windows Node、Wine apt 与 pnpm 缓存、仅限工作区快照的 hoisted 安装，以及运行工作区构建与生产网站的共享 Wine 门禁脚本。Node 分发文件传输采用有界重试；nodejs.org 的大文件传输停滞时，由支持范围请求的传输镜像续传相同字节，但版本和 SHA-256 权威仍属于 nodejs.org，归档通过该校验前绝不会投入使用。稳定的 windows 作业 ID 仍是 all checks passed 的依赖项。已归档的 Wine 实验保留其实测取舍，而本文负责当前双通道拓扑。
每个拉取请求还会在组织自有的 dsh-windows-2025-16core 运行器上启动一个常规且独立的 windows-native 作业，名称为 windows node 24 / native complete。该作业为工作区符号链接启用开发人员模式，通过 pnpm/action-setup 的 standalone 模式提供仓库固定版本的 @pnpm/exe，在不传输 store 归档的情况下执行不可变安装，并在原生 PowerShell 下运行 pnpm run check:ci:windows-complete。因此 package script 会通过 npm_execpath 暴露 pnpm.exe，让完整清单在 Windows 上覆盖无 shell 的包管理器再进入。门禁卡住时，120 分钟超时会为其设定上限，同时不把实测性能目标当作正确性截止时间。
原生作业被刻意排除在 all-checks-passed.needs 之外，且不使用 continue-on-error：聚合流程既不等待它，也不会因它改变结论；该作业则保留自身未被掩盖的结果。工作区构建、生产网站和逐文件 100% 覆盖率检查失败会使原生作业失败。静态检查、文档、包、构建产物、lint 与快照清单在同一作业内作为观测性门禁运行；其失败保持可见，但不会改变原生聚合结果，因为这些检查的阻断性判定由 Linux 负责。
16 核通道最多同时运行 4 道外层门禁。工作区构建、生产网站验证与插桩覆盖率会立即启动。豁免重型覆盖率等待构建通过后再启动，使其临时 Oxlint 约定探针不会与源码编译竞态。每道观测性门禁只等待两道覆盖率门禁以任意结果结算后再进入可用槽位；各门禁自身的 needs 边仍要求前置门禁通过。这也使随后创建临时约定文件的静态门禁不会与任一覆盖率扫描竞态。job 内分区覆盖率使用 8 个单 worker 分片，豁免重型门禁则从 DSH_COVERAGE_MAX_WORKERS=6 获得 2 个 worker。因此初始阶段约有 10 个活动执行单元；构建结束并启动豁免重型门禁后，如果网站与插桩覆盖率仍在运行，峰值约为 11 个。观测性清单启动时，publint 最多使用 8 个 worker。每个 Vitest 项目都使用 fork worker，因为 Node 24 的 CJS lexer 致命故障可在 Windows 与 POSIX 的共享 worker 中复现。两项覆盖率门禁都将 Vitest 默认的单测试和轮询时间预算设为 30 秒，因为在完整通道并发的 Windows 插桩下，多个互不相关的进程、Git、SQLite、watcher、语法和静态门禁 fixture（测试前置数据）可能超过 15 秒。translation-pairing 合并套件只导入 scripts/ 源码和子进程，因此放入豁免重型套件门禁；V8 插桩不会为它贡献任何阈值覆盖率，却会放大 Git 进程延迟。Lefthook 并发 fixture 保留原有结果，采用 30 秒单用例预算与 10 秒进程就绪探测；安装器则允许被抢占的 lock 持有者在独占创建后用 5 秒发布记录。directory-picker 组合为防抖配置写入提供显式的 15 秒轮询预算；workspace-context 组合 fixture 使用测试自有、没有无关 1 秒截止时间的信号。这些只属于该通道的预算保留了原有断言结果，120 分钟的 job 截止时间仍会约束卡死的运行。LSP 源码与 ACL 沙箱源码仍计入 Windows 分母：基于 stub 的失败路径套件把每个进程内 ACL 沙箱文件都带到 100%，只有 runner 入口保持排除——它只作为 spawn 出的子进程在插桩运行之外执行，其行为由 runner 套件端到端钉住。窄范围且带注释的 V8 ignore 只覆盖不可达分支（另一平台专属分支、生命周期内不可达的防御守卫），其行为测试仍保留在所属平台。
16 核配置是这项清单经实测选定的容量规格。使用 6 个 coverage worker 的试验分别以 6 分 27 秒和 7 分 50 秒跑出完整通过结果，而在单个插桩 Vitest 进程内使用 4 个、3 个和 2 个并发 worker 的分支头精确试验暴露出不稳定的 fixture 与 worker 退出。相互独立的单 worker 子进程保留进程隔离。16 分片样本把插桩覆盖率缩短到 112.66–122.01 秒，但还未计入豁免、构建与网站工作就已经占满整台宿主；8 个分片刻意用部分延迟换取余量。32 核对比仅将聚合门禁时间缩短 1.47 秒，且仍在 fork worker 内触发 CJS lexer 致命故障，因此增加核心数没有带来可靠的墙钟时间改善。
首次原生运行暴露出两项被兼容性通道掩盖的故障。文档投影测试此前只按 / 拆分来派生图片 basename；现在改为使用 Node 根据平台计算的 basename。Chokidar 消费方收到的 %TEMP% 以 C:\\Users\\RUNNER~1 这个 8.3 别名表示，而 libuv 返回的是长目录名，导致其 Windows 事件路径断言失败。共享的设置 watcher 与凭据 watcher，以及 Cordis 的模块 HMR（热模块替换）与精确配置 HMR，现在都会在打开 watcher 前规范化现有的原生监听基准路径或层级最深的现有祖先路径，并保留尚不存在的后缀；文件访问和诊断仍使用配置路径。模块 HMR 会挂接监听器并等待主 watcher 的 ready 事件，之后插件启动才会完成，因此启动后立即发生的编辑无法与初始扫描形成竞态。HMR 验收通过相同的异步原生 realpath 操作派生预期身份，避免同步 Windows 路径写法仍保留 8.3 别名。
可移植文件系统 fixture（测试前置数据）通过 node:path 派生路径、比较原生 realpath 标识、在 Node 启动器边界保留文件 URL，只规范化由 API 负责的分隔符或行尾，并使用每个宿主均允许的文件名。仅适用于 POSIX 的信号、模式位、不可读状态和 writer lock 场景按平台设门禁；可移植故障约定则通过每个宿主均可构造的冲突，断言结构化错误码、回滚、最后有效状态、原子替换及不存在临时残留。凭据权限验证采用无效路径 fixture；该路径在每个宿主上都会于系统查找前产生表示“非缺失”的 ERR_INVALID_ARG_VALUE，而不依赖文件祖先究竟产生 ENOTDIR 还是 ENOENT。worker 死亡 fixture 会先观察其协议前置条件，再由宿主触发真实终止，而不在嵌套 Windows Worker 中调用 process.exit()；这样既保留了 worker 退出约定，也不会让外围 Vitest fork 暴露于 Node 进程级的原生退出断言。压力与集成工作负载保留原有断言；如果 Windows 插桩或进程拆卸可能超过 Vitest 默认上限，就为其设置显式的有界时间预算。
原生 watcher 使用 canonicalizeWatchPath() 对层级最深的现有祖先执行 realpath 解析；后缀缺失时，先证明该祖先是可枚举目录，再拼回后缀。这可避免 Windows 8.3 别名与长格式 libuv 事件混用，并让所有宿主在祖先为普通文件时都保留 ENOTDIR。设置、凭据、skill（技能）根与 Cordis HMR（热模块替换）在发现和诊断时保留配置路径；模块 HMR 则使用规范写法作为 Node 加载缓存标识、挂接监听器并在插件启动完成前等待主 watcher 就绪，因此启动后立即发生的编辑不会与初始扫描形成竞态。watchFollowSymlinks: false 时，若 skill 根本身是符号链接，系统不会展开最后这一级链接，从而让 Chokidar 强制执行该边界。
Windows 的持久 JSONL 路径会保留驱动器根目录的原生写法，并仅对后代路径与暂存路径应用扩展长度命名空间。ACP（Agent Client Protocol）拆卸阶梯使用真实 Node 子进程，以符合宿主语义的结果证明优雅终止与强制终止两个层级，并避免声称 Windows 会交付 POSIX 信号。产品接受裸命令时，可执行 fixture 会提供 .cmd 包装脚本与 PATHEXT。repository-cache 辅助包位于所选 Git 子路径内，因此它们声明的 file: 依赖会在 Windows 上以相同方式暴露命令包装脚本。随附的安装器会导出 pnpm 自有的 workspace-ignore 配置，保留 PNPM_HOME 作为 pnpm 数据配置，同时从生命周期 PATH 中移除该目录，并在 PATHEXT 中优先选择 .CMD；因此，嵌套 Git 包安装既不会重新加入外层 workspace，也不会让继承的 Windows pnpm 可执行文件抢在事务持有的 wrapper 之前。
启动后，只有根 fiber 与 Loader 均处于活跃状态时，系统才会继续设置 profile watcher。只有当同一次调用所记录的信号已取得关闭流程所有权时，系统才会隔离并发设置错误；无关 HMR 故障仍会响亮失败。进程关闭控制器会在根级 dispose 成功后让单次任务的正常完成流程排空 Node 剩余句柄，同时让拆卸失败、截止时间到期和信号升级继续强制退出。vendored Include 会串行化防抖写入，只对瞬时访问或忙碌故障执行有界退避重试，并确保每个由计时器触发的拒绝都得到观察。持久化最终失败后，该故障会保留在队列中，并重新抛给拆卸责任方；成功拆卸则会排空最新写入。
Shiki 会禁用 TextMate 正则的延迟编译，并在用户内容进入保持不变的逐行 tokenization（词元化）预算前预热每种启动语法，从而避免调度器争用发布不完整的高亮流。Codex 真实产品 fixture 固定使用稳定版 0.147.0 schema，并选择实际提供的命令工具与对应参数形态；这样既保留由提供方负责的协议，也能在每种宿主上证明无人值守拒绝和整棵进程树退出。
曾考虑的替代方案
让原生 Windows 成为 all checks passed 的依赖项。 这会为聚合流程提供保真度最高的 Windows 判定，但也会让每次合并等待最慢的托管作业与 Windows 容量。独立结果能让该信号保持自动产生，而不改变现有必需路径。
只在拉取请求上运行 Wine。 Wine 能快速触达阻断性 win32 工具链分支，但即使真实 NT、NTFS、PowerShell、进程或原生插件约定已经损坏，也可能报告绿灯。
将原生作业标记为 continue-on-error。 门禁失败后，该设置会让其检查显示为成功。保留常规独立作业可维持诊断结论；仅从聚合流程的 needs 中省略它，才是不阻断的机制。
排除看似不受支持的文件或削弱 Windows fixture。 不予采纳，因为受影响的 LSP、watcher、持久化、客户端与进程行为均受支持。仅适用于另一平台的分支采用窄范围标注；可移植结果继续计入分母，并通过符合真实宿主行为的 fixture 验证。
保留 GitHub 标准的 windows-2025 运行器。 该可移植双核镜像能可靠完成这份完整清单，但其 32 分钟的串行结果使自动原生信号的实用性远低于所选的 16 核运行器。
使用 32 核或更大的运行器。 32 核对比仅比 16 核将聚合门禁时间缩短 1.47 秒，且仍因 Node 的 CJS lexer 失败；先前高并发的 32 核和 64 核试验也以同类故障失败。因此，增加容量只会提高资源分配成本，却不能带来稳定的端到端收益。
后果
Wine 保留必需聚合流程现有的关键路径和作业身份。all checks passed 变绿时，原生 Windows 仍可能处于待处理或红灯状态，因此分支保护采用 Wine 结果，而评审者和后续自动化采用独立的原生结果。
尽管如此，每个拉取请求都会获得真实 NT 内核、NTFS、PowerShell、Windows 进程、原生插件和受支持源码覆盖率信号。原生作业会重复设置流程与两项阻断构建，在标准镜像上明显更慢；但它也会暴露兼容性通道掩盖的路径、watcher、生命周期与 fixture 缺陷。
维护者必须保留两种有意设计的执行拓扑：Wine 快照使用 Linux 安装加 hoisted 布局来触达 win32 二进制文件，而原生作业在组织自有的 16 核 Windows 运行器上使用不可变工作区。任一作业独有的失败都必须依据该边界分类，不得削弱或静默跳过。
