A model that sees only the preview needs an accurate account of the omission and a way to inspect the captured text, without treating another session's instructions as current authority. Rereading the source later would not recover the same observation when the source advances or compacts. + +## Decision + +[Session-reference preparation](../../../../packages/context/session-reference/README.md) retains its existing preview policy and per-reference JSON byte budget. Each truncated reference attempts `saveText` through optional `ctx.get("spillStore")`; an untruncated reference writes no artifact. The full transcript and bounded preview derive from the same captured user/assistant text projection, including compaction checkpoints but excluding tools, reasoning, and other injected context. No second source read occurs. + +The artifact belongs to the target session receiving the context. Its descriptive source is `{ kind: "session-reference", sessionId, label }`, where `sessionId` identifies the referenced session. [Spill storage](../../../../packages/spill/spill/README.md) accepts this minimal alternative alongside the existing tool source; it requires no fabricated tool name or call id. Storage ownership does not authorize retrieval. + +A separate omission notice outside the bounded preview JSON records exact `omittedMessages` and `omittedBytes`. It carries the saved locator and backend `retrievalHint`, or an unavailable outcome distinguishing missing storage from a failed save. This notice is model-visible content in the same durable reference message, not metadata-only UI decoration. A tiny preview budget cannot remove it. The saved transcript carries capture metadata, including `capturedFormatVersion`, and the same untrusted-background warning as the preview. Per-message JSON string fragments contain at most 64 Unicode code points per line; decoding and concatenating them restores exact text, including original newlines. This fixed artifact format keeps long single-line middles retrievable with ordinary paged file reads without changing preview retention. + +Cancellation after an asynchronous save prevents context publication, even if storage already created the artifact. The consumer does not add rollback or deletion APIs; the existing backend expiry policy governs that artifact. Replay uses the logged preview and notice and never repeats the save or source read. + +## Alternatives considered + +**Write a separate session-reference file store.** Rejected because private naming, session-scoped ownership, locator guidance, and artifact lifetime already belong to spill storage. A second store would duplicate those policies. + +**Reread the source when saving or retrieving.** Rejected because source mutation could make the artifact disagree with the preview and its captured sequence. Saving the original projection preserves the observation. + +**Put omission and retrieval data inside the bounded preview JSON.** Rejected because that spends the conversation budget on metadata and can hide the notice precisely when the budget is smallest. Separate durable model-visible text preserves both obligations. + +**Use tool provenance for every spill.** Rejected because a session reference has no model-issued tool call. Invented tool ids would misattribute the artifact rather than describe its producer. + +## Consequences + +The model can inspect text omitted from a preview without increasing the preview budget. Notices add request tokens outside that budget, and retrieval adds the requested transcript text later. Storage is best-effort: an unavailable notice is honest about loss of retrieval while the bounded preview remains usable. A saved locator can expire even while its notice remains in durable history; this feature does not promise permanent archival or recover content already removed by source compaction. + +## Verification + +The [unit suite](../../../../packages/context/session-reference/tests/session-reference.spec.ts) pins omission counts, full Unicode and control-character recovery, whole-message drops, three-reference isolation, missing and failed storage, source exclusions and mutation isolation, and cancellation before publication. The [Loader composition test](../../../../packages/context/session-reference/tests/loader-composition.spec.ts) exercises the real local store and paged `read` tool against the middle of a giant single-line message, with target-session storage ownership. The [keyless recorded-session scenario](../../../../snapshots/session/session-reference-spill/snapshot.yml) pins the durable model-visible reference context.

embeds each attempt's compact stream in assistant/message and assistant/attempt, but Host and client consumers still expanded it into per-member TimedStreamChunk arrays and did per-member work; expandAssistantStream materializes the full array before find/toReversed/break can answer. Session Stats (the projection phase of every Session open), the token meter's usage and provider-assembly folds, the subagent output fold, and the Session Controller image lookup still paid O(members) allocation and time per settlement. The Chat and Trajectory definitions were already settled from message.content on master; the remaining per-member folds stay. dsh-llm now exports record-level readers (first token, visible content, visible text, last raw chunk of a type, raw chunks of a type, joined text, run-aware assembly, per-run first-token/first-visible times) that scan the compact records once with early exit. Session Stats reads assistantStreamFirstTokenTime, the token meter reads lastAssistantStreamChunk(stream, 'usage') and assembles through assembleAssistantStream, the subagent output fold appends joinAssistantStreamText, and the Session Controller scans assistantStreamChunks(stream, 'block-end'). expandAssistantStream is deliberately not memoized: retaining expansions costs roughly ten times the compact stream for the Session's lifetime. It remains the validating path at durable boundaries.

Moving arbitrary pull-request code or credentialed publication onto a persistent shared host would weaken isolation; reusing a checkout without cleaning would also weaken the packed-payload proof. + +## Decision + +The two jobs in [release.yml](../../../../.github/workflows/release.yml) and the pack job in [release-vendor.yml](../../../../.github/workflows/release-vendor.yml) select the existing self-hosted Linux pool only with the writer-controlled `DSH_CI_FAILOVER_LINUX` repository variable set to `selfhosted`. The selector requires the canonical repository and a non-Dependabot actor, then admits only master pushes or same-repository, non-fork PRs whose author is not Dependabot. Manual dispatch always selects `ubuntu-24.04`, as do all other rejected contexts. The [failover runbook](2026-07-26-ci-failover-runbook.md) continues to own the independent main-CI switches and standby operation; this note adds only release-rehearsal eligibility. + +The runner labels are `[self-hosted, linux, x64, vm-backup]`. Runner registrations share one VM, not independent machine capacity. Each job uses its runner-private temporary volume for Node compile cache and node-gyp headers before pnpm setup, and a pnpm setup destination qualified by run, attempt, and job. The persistent pnpm store stays outside checkout cleanup; only GitHub-hosted runners restore the remote store cache. Neither rehearsal workflow saves remote caches. + +Checkout explicitly cleans ignored and untracked output before immutable installation and the existing builds. Full tag history, pack concurrency, dependency checks, tarball verification, and artifact retention remain unchanged. The packed-install verifier creates a fresh consumer outside the checkout, installs tarballs with npm, removes inherited Node resolution hooks, and deletes the consumer in `finally`; a warm pnpm store cannot substitute workspace links or stale build output for a tarball payload. The [npm release decision](2026-08-10-npm-release-sequences.md) still owns release families and publication. Both manual publish workflows remain entirely hosted and gain no credentials or registry changes here. + +## Alternatives considered + +Always-hosted rehearsals avoid persistent-host risk but retain all hosted minutes.

Allowing manual dispatch on arbitrary refs gives a maintainer action broader persistent-host access than the explicit event trust rule. + +## Consequences + +Unsetting the variable or changing it away from `selfhosted` routes subsequent eligible jobs to hosted Ubuntu.

A lower per-minute runner price does not guarantee lower job cost because GitHub rounds each job upward to whole minutes. Moving previews to persistent self-hosted machines also changes isolation and is outside this decision. + +## Decision + +The [preview workflow](../../../../.github/workflows/build-preview-cloudflare.yml) uses standard GitHub-hosted `ubuntu-24.04`. Build, cache, deployment, protected-image verification, and comment semantics remain unchanged. The [sizing reference](../../../../.github/preview-sizing/README.md) owns comparison requirements. The separate CI [failover runbook](2026-07-26-ci-failover-runbook.md) retains its independent runner-switch decision; previews do not use those switches. + +### Measurements + +[Experiment 34012729982](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34012729982) succeeds for all eight size/cache combinations plus one cache seed. Every measured job checks out SHA `9149d7e7ef945b5601711badd3cf63d58ab384f5`, uses Node 24.19.0 and pnpm 11.7.0, and executes immutable install, full workspace build, preview/VFS packing, and local upload shaping with gzip integrity verification. Warm jobs restore one exact run-private pnpm cache; cold jobs skip restoration but contain pnpm bootstrap files. No compiled outputs are restored. + +| Runner | Cold / warm job seconds | Rounded minutes each | USD each | Workspace seconds cold / warm | Preview seconds cold / warm | +|---|---:|---:|---:|---:|---:| +| standard, 2 vCPU | 202 / 203 | 4 | 0.024 | 138.92 / 147.21 | 12.65 / 12.94 | +| larger, 4 vCPU | 177 / 162 | 3 | 0.036 | 124.21 / 114.86 | 10.77 / 9.88 | +| larger, 8 vCPU | 154 / 154 | 3 | 0.066 | 110.51 / 110.77 | 9.20 / 9.21 | +| larger, 16 vCPU | 124 / 125 | 3 | 0.126 | 90.57 / 84.99 | 7.62 / 7.33 | + +Using [published rates](https://docs.github.com/en/billing/reference/actions-runner-pricing), measured jobs total $0.504; the 60-second standard seed adds $0.006. The $0.510 gross compute estimate includes setup, restoration, measurement upload, and cleanup, but excludes storage and account discounts. Standard costs 80.95% less than 16-core and 33.33% less than 4-core in each sampled cache state. It adds 78 seconds against the corresponding 16-core job. + +Standard jobs expose two vCPUs and 7.75 GiB RAM. Workspace maximum process RSS is 2.86 / 2.76 GiB; preview maximum process RSS is 0.76 / 0.74 GiB. Both complete without an OOM or timeout. GNU time RSS is not simultaneous process-tree memory. These samples establish successful execution, not a permanent memory guarantee. + +The comparison fixes source, lockfile, commands, and runtime versions, not physical CPUs or image release: standard and 4-core use image 20260831.293.1; 8-core and 16-core use 20260823.283.1. CPUs vary among AMD EPYC 9V74/7763 and Intel Xeon 8370C/8573C. One sample per cache state measures the offered labels, not isolated CPU scaling or statistical repeatability. + +The experiment does not deploy or access Cloudflare credentials. Measurement upload takes zero to one second; warm-cache restore takes six to ten seconds. For context, [production job 101428009994](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34011495156/job/101428009994) spends 14 seconds uploading, one second verifying, and two seconds commenting on a different SHA. Adding that overhead to this experiment is a projection, not a measured standard-runner publication result. The actual PR preview workflow owns deployment confirmation. + +## Alternatives considered + +**Keep 16-core.** It provides the shortest measured job, but costs $0.102 more per sample for a 78-second improvement. Preview builds do not justify that premium for this cost-focused decision. + +**Select 4-core or 8-core.** Both succeed and shorten builds, but their rounded sample costs exceed standard Ubuntu. Four-core retains more RAM and disk headroom if future workloads exhaust standard capacity; such a change requires new measurements. + +**Move to self-hosted.** Rejected by scope: previews remain on GitHub CI. The existing Linux and Windows registrations can share persistent hosts; their dependency, store-volume, and cleanup assumptions do not apply to fresh hosted VMs. No failover or trust condition changes. + +## Consequences + +Previews trade approximately 78 seconds of sampled build-job latency for lower compute cost. Production Cloudflare latency, image rollout variance, future build growth, and broader success rates remain observable limitations. No hourly or monthly savings are extrapolated from this single experiment. The temporary benchmark workflow and its safety test are absent from the final tree; the experiment commits and linked run preserve the method and evidence. + +The executed [focused regression](../../../../scripts/preview-workflow.spec.ts) pins hosted routing, PR triggers and permissions, immutable full builds, restore-only caching, publication shaping, protected-image checks, and idempotent comments. A physical self-hosted routing mutation fails its routing assertion; restoration passes all three tests. No model-visible runtime behavior changes, so no Session snapshot changes are required. diff --git a/.agents/notes/implemented/process/2026-09-06-preview-hosted-runner-sizing.zh.md b/.agents/notes/implemented/process/2026-09-06-preview-hosted-runner-sizing.zh.md new file mode 100644 index 0000000000..285b21d60d --- /dev/null +++ b/.agents/notes/implemented/process/2026-09-06-preview-hosted-runner-sizing.zh.md @@ -0,0 +1,46 @@ +# Agent Note: 基于测量的 GitHub 托管 PR 预览规格 + +Status: implemented + +[English](2026-09-06-preview-hosted-runner-sizing.md) | 中文 + +## 问题 + +PR（Pull Request）预览构建完整工作区及浏览器 worker VFS 镜像。较低的每分钟运行器价格不能保证较低的作业成本，因为 GitHub 将每个作业向上取整至整分钟。将预览移至持久化自托管机器还会改变隔离方式，不属于本决策范围。 + +## 决策 + +[预览工作流](../../../../.github/workflows/build-preview-cloudflare.yml) 使用标准 GitHub 托管 `ubuntu-24.04`。构建、缓存、部署、受保护镜像验证及评论语义保持不变。[规格参考](../../../../.github/preview-sizing/README.zh.md) 负责比较要求。独立的 CI [故障切换手册](2026-07-26-ci-failover-runbook.zh.md) 保留其运行器切换决策；预览不使用这些开关。 + +### 测量 + +[实验 34012729982](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34012729982) 的八种规格/缓存组合及一个缓存预热作业均成功。每个测量作业检出 SHA `9149d7e7ef945b5601711badd3cf63d58ab384f5`，使用 Node 24.19.0 与 pnpm 11.7.0，并执行不可变安装、完整工作区构建、预览/VFS 打包，以及含 gzip 完整性验证的本地上传内容整理。热作业恢复同一个运行私有精确 pnpm 缓存；冷作业跳过恢复，但包含 pnpm 引导安装文件。不恢复编译产物。 + +| 运行器 | 冷 / 热作业秒数 | 各自取整分钟数 | 各自美元费用 | 冷 / 热工作区秒数 | 冷 / 热预览秒数 | +|---|---:|---:|---:|---:|---:| +| 标准，2 vCPU | 202 / 203 | 4 | 0.024 | 138.92 / 147.21 | 12.65 / 12.94 | +| 大型，4 vCPU | 177 / 162 | 3 | 0.036 | 124.21 / 114.86 | 10.77 / 9.88 | +| 大型，8 vCPU | 154 / 154 | 3 | 0.066 | 110.51 / 110.77 | 9.20 / 9.21 | +| 大型，16 vCPU | 124 / 125 | 3 | 0.126 | 90.57 / 84.99 | 7.62 / 7.33 | + +按[公开费率](https://docs.github.com/en/billing/reference/actions-runner-pricing)，测量作业合计 $0.504；60 秒标准预热作业增加 $0.006。$0.510 总计算费用估算包含设置、恢复、测量上传及清理，但不含存储和账户折扣。在每种采样缓存状态下，标准运行器比 16 核低 80.95%，比 4 核低 33.33%。相比对应的 16 核作业增加 78 秒。 + +标准作业提供两个 vCPU 与 7.75 GiB 内存。工作区最大进程 RSS 为 2.86 / 2.76 GiB；预览最大进程 RSS 为 0.76 / 0.74 GiB。两者均未发生 OOM 或超时并完成。GNU time RSS 不是进程树同时占用的内存总量。这些样本证明成功执行，而非永久内存保证。 + +比较固定源代码、锁文件、命令和运行时版本，但不固定物理 CPU 或镜像版本：标准与 4 核使用镜像 20260831.293.1；8 核与 16 核使用 20260823.283.1。CPU 包括 AMD EPYC 9V74/7763 与 Intel Xeon 8370C/8573C。每种缓存状态的单个样本测量所提供的标签，而非独立 CPU 扩展性或统计可重复性。 + +实验不部署，也不访问 Cloudflare 凭据。测量上传耗时零至一秒；热缓存恢复耗时六至十秒。作为背景，[生产作业 101428009994](https://github.com/deepseek-harness/deepseek-harness/actions/runs/34011495156/job/101428009994) 在不同 SHA 上上传耗时 14 秒、验证一秒、评论两秒。将该开销加至本实验属于推算，而非已测量的标准运行器发布结果。实际 PR 预览工作流负责部署确认。 + +## 考虑过的替代方案 + +**保留 16 核。** 它提供最短的测量作业，但为 78 秒改善使每个样本增加 $0.102。对于本次以成本为重点的决策，预览构建不值得这项溢价。 + +**选择 4 核或 8 核。** 两者均成功并缩短构建，但取整后的样本费用高于标准 Ubuntu。若未来工作负载耗尽标准容量，4 核可保留更多内存与磁盘余量；这样的变更需要新测量。 + +**移至自托管。** 因范围限制而拒绝：预览保留在 GitHub CI。现有 Linux 与 Windows 注册实例可能共享持久化主机；其依赖、store 卷及清理假设不适用于全新的托管 VM。不改变故障切换或信任条件。 + +## 影响 + +预览以约 78 秒采样构建作业延迟换取更低的计算费用。生产 Cloudflare 延迟、镜像发布差异、未来构建增长及更广泛的成功率仍是可观测限制。不从本次单一实验外推每小时或每月节省。最终文件树不包含临时基准工作流及其安全测试；实验提交与链接的运行保留方法和证据。 + +已执行的[针对性回归](../../../../scripts/preview-workflow.spec.ts) 固定托管路由、PR 触发器与权限、不可变完整构建、只恢复缓存、发布内容整理、受保护镜像检查及幂等评论。实际修改为自托管路由会使路由断言失败；恢复后全部三个测试通过。不改变模型可见运行时行为，因此不需要修改 Session 快照。 diff --git a/.github/preview-sizing/README.i18n.yaml b/.github/preview-sizing/README.i18n.yaml new file mode 100644 index 0000000000..cd5241c300 --- /dev/null +++ b/.github/preview-sizing/README.i18n.yaml @@ -0,0 +1,6 @@ +# Bilingual-pair consistency record (docs/i18n/README.md): the git blob hash of each +# side as of the last confirmed-consistent state.

GitHub ke The decision belongs at workflow level because cancellation applies to the whole superseded run: a job-level `concurrency` group does not exempt its job. The negated form is load-bearing rather than cosmetic: naming `pull_request` alone would also stop cancelling `workflow_dispatch`, and each runner benchmark fans out to twelve larger runners for up to fifteen minutes inside this same group on master, so a re-dispatch would queue ahead of a drill instead of replacing a stale measurement. What bounds the cost is that a master push in `ci-master.yml` carries only `wine-apt-cache` and these two drills; the pull-request jobs live in the separate `ci.yml` (which does not see `push`), and the benchmarks are `workflow_dispatch`-gated within `ci-master.yml`. `scripts/ci-workflow.spec.ts` pins that push-reachable set — classifying by exact condition, since a negated event test mentions the event it excludes — so a new push-reachable job cannot quietly start accumulating uncancelled runs. +### Release rehearsals share the Linux switch + +`DSH_CI_FAILOVER_LINUX=selfhosted` also routes the credential-free dependency-layout job and both dsh/vendor pack jobs onto `vm-backup` for eligible same-repository PRs and master pushes.

Both manual publish workflows remain entirely hosted and gain no credentials or registry changes here. diff --git a/.agents/notes/implemented/process/2026-09-06-release-rehearsal-selfhosted.zh.md b/.agents/notes/implemented/process/2026-09-06-release-rehearsal-selfhosted.zh.md index 1b90bbe850..a6fa441d01 100644 --- a/.agents/notes/implemented/process/2026-09-06-release-rehearsal-selfhosted.zh.md +++ b/.agents/notes/implemented/process/2026-09-06-release-rehearsal-selfhosted.zh.md @@ -10,9 +10,9 @@ Status: implemented ## Decision -[release.yml](../../../../.github/workflows/release.yml) 的两个作业和 [release-vendor.yml](../../../../.github/workflows/release-vendor.yml) 的打包作业仅在写权限维护者控制的仓库变量 `DSH_CI_FAILOVER_LINUX` 设为 `selfhosted` 时选择现有 Linux 自托管池。选择器要求当前仓库为正式仓库且触发者不是 Dependabot，然后只接纳 master 推送，或作者不是 Dependabot 的同仓库、非 fork PR（Pull Request）。手动触发始终选择 `ubuntu-24.04`，其他不满足条件的上下文也一样。[故障切换手册](2026-07-26-ci-failover-runbook.zh.md) 继续负责独立的主 CI 开关与热备操作；本记录只增加发布演练的准入规则。 +[release.yml](../../../../.github/workflows/release.yml) 的两个作业和 [release-vendor.yml](../../../../.github/workflows/release-vendor.yml) 的打包作业仅在写权限维护者控制的仓库变量 `DSH_CI_FAILOVER_LINUX` 设为 `selfhosted` 时选择现有 Linux 自托管池。选择器要求当前仓库为正式仓库且触发者不是 Dependabot，然后只接纳 master 推送，或作者不是 Dependabot 的同仓库、非 fork PR（Pull Request）。手动触发始终选择 `ubuntu-24.04`，其他不满足条件的上下文也一样。[故障切换手册](2026-07-26-ci-failover-runbook.zh.md) 负责按平台划分的开关与热备操作。发布演练有意与主 CI 共用 Linux 开关：启用或禁用会同时路由两类负载，不能独立切换发布演练。未设置时仍默认使用托管池；只有运维人员选择 `selfhosted` 期间才节省托管分钟，无论该选择用于故障恢复还是持续的成本控制。 -运行器标签为 `[self-hosted, linux, x64, vm-backup]`。运行器注册共享一台虚拟机，不代表独立机器容量。每个作业在 pnpm 设置前将 Node 编译缓存与 node-gyp 头文件放在运行器私有临时卷上，pnpm 设置目标路径包含运行、重试次数和作业标识。持久化 pnpm 存储位于检出清理范围之外；只有 GitHub 托管运行器恢复远端存储缓存。两个演练工作流都不保存远端缓存。 +运行器标签为 `[self-hosted, linux, x64, vm-backup]`。运行器注册共享一台虚拟机，不代表独立机器容量。每个作业在 pnpm 设置前将 Node 编译缓存与 node-gyp 头文件放在运行器私有临时卷上，pnpm 设置目标路径包含运行、重试次数和作业标识。`TMPDIR` 也指向 `runner.temp`，因此临时 npm 消费目录既在检出目录之外，也在运行器清理范围之内，即使进程被强杀而无法执行 `finally` 也一样。持久化 pnpm 存储位于检出清理范围之外；只有 GitHub 托管运行器恢复远端存储缓存。两个演练工作流都不保存远端缓存。 检出操作显式清理被忽略和未跟踪的输出，再执行锁定依赖安装与现有构建。完整标签历史、打包并发、依赖检查、压缩包验证和产物保留期均保持不变。打包安装验证器在检出目录外创建全新的消费目录，用 npm 安装压缩包，移除继承的 Node 解析钩子，并在 `finally` 中删除消费目录；预热 pnpm 存储无法用工作区链接或过期构建输出代替压缩包载荷。[npm 发布决策](2026-08-10-npm-release-sequences.zh.md) 仍负责发布族与发布操作。两个手动发布工作流全部保留在托管运行器上，本改动不增加凭据，也不改变注册表。 diff --git a/.github/workflows/release-vendor.yml b/.github/workflows/release-vendor.yml index cd285e1d01..ddf3c3f96c 100644 --- a/.github/workflows/release-vendor.yml +++ b/.github/workflows/release-vendor.yml @@ -53,6 +53,7 @@ jobs: run: | echo "NODE_COMPILE_CACHE=${{ runner.temp }}/node-compile-cache" >> "$GITHUB_ENV" echo "npm_config_devdir=${{ runner.temp }}/node-gyp" >> "$GITHUB_ENV" + echo "TMPDIR=${{ runner.temp }}" >> "$GITHUB_ENV" - uses: pnpm/action-setup@v4 with: diff --git a/.github/workflows/release.yml b/.github/workflows/release.yml index d9812e9ab7..1e6662149e 100644 --- a/.github/workflows/release.yml +++ b/.github/workflows/release.yml @@ -50,6 +50,7 @@ jobs: run: | echo "NODE_COMPILE_CACHE=${{ runner.temp }}/node-compile-cache" >> "$GITHUB_ENV" echo "npm_config_devdir=${{ runner.temp }}/node-gyp" >> "$GITHUB_ENV" + echo "TMPDIR=${{ runner.temp }}" >> "$GITHUB_ENV" - uses: pnpm/action-setup@v4 with: @@ -111,6 +112,7 @@ jobs: run: | echo "NODE_COMPILE_CACHE=${{ runner.temp }}/node-compile-cache" >> "$GITHUB_ENV" echo "npm_config_devdir=${{ runner.temp }}/node-gyp" >> "$GITHUB_ENV" + echo "TMPDIR=${{ runner.temp }}" >> "$GITHUB_ENV" - uses: pnpm/action-setup@v4 with: diff --git a/scripts/tests/ci-release-selfhosted.spec.ts b/scripts/tests/ci-release-selfhosted.spec.ts index 0b42c313ed..99ce317248 100644 --- a/scripts/tests/ci-release-selfhosted.spec.ts +++ b/scripts/tests/ci-release-selfhosted.spec.ts @@ -28,8 +28,9 @@ function workflow(file: string): Workflow { return load(readFileSync(resolve(root, '.github/workflows', file), 'utf8')) as Workflow } -// These selectors use only string/boolean comparisons and short-circuit operators, -// shared by Actions and JavaScript;
