ci: publish via npm trusted publishing (OIDC), no long-lived token (CEL-1733) - #17
Merged

Conversation
Mirrors the beverage-utils shape: upgrade npm to >=11.5.1, gate the whole job on package.json's version having actually changed vs HEAD~1, keep the unauthenticated npm-view guard, and drop NODE_AUTH_TOKEN/NPM_TOKEN from the publish step. Provenance stays automatic (public repo + public package). (CEL-1733)

WalkthroughThe publishing workflow now uses GitHub Actions OIDC for npm Trusted Publishing. It gates validation and publishing on package version changes. The README documents the automated publishing process and provenance generation. Changesnpm publishing workflow

In @.github/workflows/publish.yml:
- Line 16: Update the publish workflow’s version-change detection to compare
package.json at github.event.before against HEAD, rather than relying on HEAD~1,
so multi-commit pushes detect the bump correctly. Fetch the push base needed for
that comparison while preserving the existing empty-base fallback for first
pushes.
- Line 8: In .github/workflows/publish.yml lines 8-8 and 29-29, pin the
OIDC-enabled job’s actions/checkout@v4 and actions/setup-node@v4 references to
reviewed full commit SHAs, and replace npm install -g npm@latest with an exact
reviewed npm version of at least 11.5.1. Update both affected sites as needed
while preserving the publish workflow behavior.

| Status | Acceptance criteria | Notes |
|---|---|---|
| ✅ | Configure npm Trusted Publishing with GitHub Actions OIDC and remove the long-lived publish token | The workflow grants id-token write permission and publishes without NODE_AUTH_TOKEN or NPM_TOKEN. |
| ✅ | Use npm CLI version compatible with Trusted Publishing | The workflow upgrades npm before dependency installation or publishing. |
| ✅ | Publish only after a package version change on main, with an existing-version guard | The workflow compares the current package version with HEAD~1 and then checks npm before publishing. |
| ✅ | Run install, tests, and build before publishing | All three validation steps run when the version-change gate passes, before the npm view guard and publish steps. |
| ✅ | Publish the public package with automatic provenance | The workflow publishes with public access and omits the explicit provenance flag because Trusted Publishing generates provenance for this public repository and package. |
| Document the automated publishing flow and required npm Trusted Publisher configuration | README documentation and the required npmjs.com configuration are described, but the external Trusted Publisher row is a manual prerequisite and is not evidenced as configured in the diff. | |
| Validate the workflow and verify the first real publish | The PR reports a clean actionlint result, but first-publish verification is necessarily deferred until a subsequent version bump after the npm configuration is completed. |

Pin npm to ^11.5.1 instead of @latest, scope permissions to the publish job, gate the version check against github.event.before (rebase-merge safe) with HEAD~1 fallback, and document why --ignore-scripts is kept for this package's install step.
