cordis 4.0.0-rc.6, plugin-loader, -include, -group, -timer, -hmr, -logger-console, cosmokit 1.8.1, schemastery 3.18.0 — copied from the cordis-workspace checkout, flattened under vendor/, original npm names, private: true. vendor/README.md is the manifest: upstream repos + commit SHAs, local-modification log, sync procedure. Local modification: hmr's locale YAML imports and .i18n() call removed (avoids a runtime YAML import hook we don't vendor).
