Libnode-shaped Fixture

Libnode-shaped Fixture

This fixture models the Buildchain contract needed by kungfu-systems/libnode without running the real native build.

It is intentionally small, but it keeps the important shape:

• package.json is the package version-state file;
• libnode.release.json is the explicit upstream anchor manifest;
• buildchain.toml declares install, build, verify, and publish lifecycle stages;
• version.strategy = "anchored" and version.next = "manual" tell Buildchain to validate the current anchor instead of deriving the next Node anchor automatically;
• lifecycle commands are Node-based and cross-platform;
• build output lands under dist/, which the reusable build workflow uploads with a deterministic artifact name and manifest;
• .github/workflows/build.yml exercises the public build.yml@v3 channel router with a caller job named build, including its stable top-level build / Summarize build contract aggregate;
• the fixture can be resolved through a publish-gate source lock, which binds the requested consumer version to package.json and libnode.release.json before any publish side effect is allowed;
• [publish] declares the normal token-free path: mode = "publish-final-version" with auth = "trusted-publishing", latest as the release dist-tag, and platform packages published before the main package.
