 The cold Host reference build takes 23.49 seconds with 1.91 GiB peak RSS, compared with 84.01 seconds and 3.87 GiB for the complete compiler pass. All 5,932 emitted files match by path and SHA-256. These are single local compiler samples, excluding bundling and tests; current-head CI owns the PR latency result. The benchmark scenarios and their budgets remain unchanged.
 
+Parallel packing relies on the pinned pnpm CLI to honor exact recursive filters, the pack destination, the workspace concurrency limit, and each package's lifecycle hooks. A pnpm upgrade must pass the real-CLI checks in `scripts/release/pack.spec.ts` before release packing adopts it.
+
+Coverage weights sum Vitest's distinct environment, preparation, setup, collection, and execution costs. CI's platform/environment/pool cache prefixes exclude the previous `coverage-times-<run>` archives. Persistent local checkouts can retain wall-clock weights for files not measured during rollout; removing `.coverage-times.json` resets that history. These advisory weights affect partition assignment, while the complete inventory and merged coverage thresholds remain required.
+
 Artifact builds deliberately do not diagnose aggregate-only test or script errors. Required normal builds reject those errors; fixture checks also reject package errors on both paths and compare emitted JavaScript, declarations, maps, and build information. Removing or changing a required full build requires transferring both aggregate checks to another blocking owner first. Master serial references remain complete under their [existing policy](2026-07-21-serial-cross-platform-ci-reference.md).

 冷启动 Host reference 构建耗时 23.49 秒、峰值 RSS 为 1.91 GiB；完整编译器阶段为 84.01 秒和 3.87 GiB。全部 5,932 个 emit 文件的路径与 SHA-256 相同。这些是单次本地编译器样本，不含 bundling 和测试；PR 延迟结果以当前 head 的 CI 为准。benchmark 场景与预算保持不变。

+覆盖率权重累加 Vitest 互不重叠的 environment、preparation、setup、collection 和 execution 成本。CI 的平台/environment/pool cache prefix 不匹配原来的 `coverage-times-<run>` archive。持久化本地 checkout 在切换期间可能为未测量的文件保留墙钟权重；删除 `.coverage-times.json` 可重置该历史。这些参考权重影响分区分配，完整清单与合并后的覆盖率阈值仍然必需。

 产物构建有意不诊断仅属于 aggregate 的测试或脚本错误。必需的普通构建拒绝这些错误；fixture 检查还验证两个路径都会拒绝包错误，并比较 emit 的 JavaScript、声明、map 和 build 信息。删除或改变必需的完整构建前，必须先把两个 aggregate 检查转交另一处阻塞型 owner。master 串行 reference 按[现有政策](2026-07-21-serial-cross-platform-ci-reference.zh.md)保持完整。
