+# npm trusted publishing
+
+The `node-publish` job in `.github/workflows/CI.yml` publishes through GitHub
+Actions OIDC. It runs only on pushes to `main`, uses Node.js 24 and npm 11, and
+does not use `NPM_TOKEN`. PyPI and crates.io publication are separate.
+
+## Registry setup
+
+Configure a GitHub Actions trusted publisher in the npm settings of **each**
+package:
+
+- `@dependency-check-updates/cli`
+- `@dependency-check-updates/cli-win32-x64-msvc`
+- `@dependency-check-updates/cli-darwin-x64`
+- `@dependency-check-updates/cli-linux-x64-gnu`
+- `@dependency-check-updates/cli-darwin-arm64`
+
+Use these exact values:
+
+| Field | Value |
+| --- | --- |
+| Organization or user | `dev-five-git` |
+| Repository | `dependency-check-updates` |
+| Workflow filename | `CI.yml` |
+| Environment name | Leave empty |
+| Allowed actions | Enable direct `npm publish` |
+
+The filename is case-sensitive and must not include `.github/workflows/`.
+Changing the workflow filename requires updating the registry configuration.
+The job already has `id-token: write`. Configure every platform package before
+enabling this workflow; configuring only the CLI package is insufficient.
+After a successful OIDC release, remove the obsolete repository `NPM_TOKEN`
+secret and revoke the old token if no other project uses it.
+
+## Packaging and verification
+
+After building the CLI and collecting all platform artifacts:
+
+```sh
+cd bridge/node
+bun run pack:publish /absolute/path/to/new-output-directory
+```
+
+The script runs N-API preparation with optional publication and GitHub release
+creation disabled. It checks that every target has a platform package with the
+CLI version, packs the native packages and CLI with `bun pm pack`, and inspects
+the actual tarballs for unresolved local dependency ranges and missing entry
+points or native binaries. Bun converts `workspace:` ranges before npm sees
+the tarballs. The packing script expands Windows 8.3 path aliases before
+passing package directories to Bun, preserving workspace resolution on Windows
+CI runners. An existing output directory is rejected to prevent stale files
+from entering a release.
+
+CI completes all checks before publishing anything. It publishes the tarballs
+under `native/` first, then the tarball under `cli/`, using
+`npm publish <tarball> --access public --ignore-scripts`. Do not replace this
+with publication from source directories: npm does not materialize Bun
+workspace protocols. `prepublishOnly` now prepares packages without publishing
+the platform packages automatically.
+Already published versions are skipped for each package individually, so a
+partial publication or failed GitHub release asset upload can be retried.
+
+The packaging regression test uses a real native binary, a `workspace:^`
+fixture, and the same packing script. It checks the materialized range, rejects
+a `file:` dependency, and installs both tarballs offline before running the CLI.
