Run CI examples from built lib

在 CI 中从构建后的 lib 运行示例

CI boots examples and Cordis-backed test projects through `node --import tsx` and the root tsconfig `paths` map. This adds TypeScript transformation cost and changes package resolution: imports resolve to workspace source instead of following package `exports` into built `lib/`. These runs therefore do not test the same code or resolution behavior as an installed consumer. A package can pass CI while its built export

Problem

CI boots examples and Cordis-backed test projects through node --import tsx and the root tsconfig paths map. This adds TypeScript transformation cost and changes package resolution: imports resolve to workspace source instead of following package exports into built lib/.

These runs therefore do not test the same code or resolution behavior as an installed consumer. A package can pass CI while its built export graph is incomplete or resolves differently.

Decision

Execution has two modes. src is the default local-development mode and uses tsx; lib is the strict CI mode and starts built bins with plain Node, without tsx or tsconfig path mapping.

  • CI subprocesses that boot an example or a checked-in cordis.yml use lib mode.
  • TypeScript fixtures that only implement an ACP or MCP peer and do not load Cordis run directly with Node. An explicit source-path regression may remain in src mode.

Resolution topology

Every test Cordis config must resolve its bare modules by walking upward from the config directory.

  • examples/ is one pnpm workspace member and provides the shared examples/node_modules resolution root.
  • Every checked-in test Cordis config, including snapshot configs and package-owned fixtures, lives under its corresponding examples/<agent>/ tree. A config owned by packages/<group>/<package>/ maps to examples/<agent>/tests/fixtures/<group>/<package>/cordis.yml; the test driver and assertions remain package-local.
  • Every package named by an example Cordis config is declared in both examples/package.json for lib resolution and the root tsconfig.json references for src mode.

Launch policy

The shared Loader test harness selects src or lib from DSH_EXAMPLE_MODE. CI builds first and selects lib; an unset mode keeps the fast local source loop.

Alternatives considered

  • Keep CI on tsx — rejected because it preserves transformation overhead and source-only resolution behavior.
  • Use lib everywhere — rejected because local development would require a build before every run. Dual mode keeps that cost out of the development loop.
  • Build a private node_modules tree per test — rejected because it duplicates consumer scaffolding. The examples/ workspace root gives every Cordis config one real and declared resolution path.

Consequences

  • CI validates built package exports without tsx changing module resolution; local development retains the no-build source loop.
  • CI must build before these tests, and manual lib runs can observe stale local artifacts.
  • Cordis config dependencies are not visible to normal TypeScript import analysis, so examples/package.json and the root tsconfig references must stay synchronized with the configs.

问题

CI 通过 node --import tsx 和根 tsconfig 的 paths 映射启动示例与加载 Cordis 配置的测试项目。这种方式既增加了 TypeScript 转换开销,也改变了包解析行为:import 会解析到 workspace 源码,而不是经包的 exports 进入构建后的 lib/

因此,这些测试没有覆盖已安装消费方实际运行的代码和解析路径。即使包的构建导出图不完整或解析结果不同,CI 仍可能通过。

决策

执行机制包含两种模式。src 是本地开发的默认模式并使用 tsx;lib 是严格的 CI 模式,通过 plain Node 启动构建后的 bin,不加载 tsx,也不使用 tsconfig 路径映射。

  • CI 中启动示例或签入仓库的 cordis.yml 的子进程使用 lib 模式。
  • 仅实现 ACP 或 MCP 对端、且不加载 Cordis 的 TypeScript fixture(测试前置数据)直接由 Node 运行。只有显式验证源码路径的回归测试可以保留 src 模式。

解析拓扑

每个测试 Cordis 配置都必须能从配置文件所在目录向上解析裸模块。

  • examples/ 作为一个 pnpm workspace 成员,提供统一的 examples/node_modules 解析根目录。
  • 所有签入仓库的测试 Cordis 配置,包括快照配置和包内测试 fixture,都放在对应的 examples/<agent>/ 目录树下。归属 packages/<group>/<package>/ 的配置映射到 examples/<agent>/tests/fixtures/<group>/<package>/cordis.yml;测试驱动和断言仍留在包内。
  • 示例 Cordis 配置中引用的每个包都同时登记在 examples/package.json 和根 tsconfig.json 的 references 中,分别支持 libsrc 解析。

启动策略

共享 Loader 测试 harness 通过 DSH_EXAMPLE_MODE 选择 srclib。CI 先构建再选择 lib;未设置模式时保留快速的本地源码开发回路。

曾考虑的替代方案

  • CI 继续使用 tsx:不予采纳,因为它会保留转换开销和仅适用于源码的解析行为。
  • 所有环境只使用 lib:不予采纳,因为本地开发每次运行前都必须构建。双模式避免把这项成本带入开发回路。
  • 每个测试单独构造 node_modules:不予采纳,因为它会重复消费方脚手架。以 examples/ 作为 workspace 根,可让每个 Cordis 配置通过同一条真实且显式声明的路径解析模块。

后果

  • CI 可以验证构建后的包导出,不再受 tsx 模块解析影响;本地开发仍保留免构建的源码回路。
  • CI 必须先构建再运行这些测试;手动执行 lib 模式时可能读取陈旧的本地产物。
  • 常规 TypeScript import 分析无法识别 Cordis 配置依赖,因此 examples/package.json、根 tsconfig references 与配置文件必须保持同步。
