ci: publish releases through GitHub OIDC

[oritwoen]

Adds tag-triggered trusted publishing without a long-lived npm token, on the same pinned pnpm workflow the rest of the org uses.

pnpm test:run rather than pnpm test, because plain test stays in watch mode here. --no-git-checks on the publish step because a tag checkout is detached and pnpm otherwise stops at ERR_PNPM_GIT_UNKNOWN_BRANCH; agntn/chains lost its v0.2.0 release to exactly that. And release no longer ends in pnpm publish, since the tag it pushes now triggers this workflow and a second publish would only collide.

One thing this cannot do: npm attaches a trusted publisher to a package that already exists, so @agntn/explorers still needs its first version published by hand before OIDC takes over.

📝 Walkthrough

Walkthrough

The pull request adds a GitHub Actions workflow that publishes the package after a v* tag push. The workflow checks out the repository, configures Node.js and pnpm, installs dependencies, runs tests, and publishes the package.

Changes

Package publishing

Layer / File(s)	Summary
Version-tag publishing workflow .github/workflows/publish.yml	The workflow runs for v* tag pushes. It uses scoped permissions, configures Node.js 24 and pnpm, installs dependencies, runs tests, and publishes the package.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔴 Critical · up to 232ce

Tag-triggered releases may fail before publishing, and a tag can publish a package under the wrong version because the tag and package version are not verified. The PR should not merge until these release-blocking issues are fixed.

Poem

I’m a rabbit with a tag in sight,
The package hops to publish right.
Tests run first, then off we go,
With Node and pnpm in a row.
“Ship it!” I twitch my nose—
A tidy workflow now it flows.

19-27: 🩺 Stability & Availability

No change required for pnpm OIDC publishing. pnpm@10.33.4 includes the fix for unresolved ${NODE_AUTH_TOKEN} placeholders used by actions/setup-node, so the workflow can use OIDC publishing without setting NODE_AUTH_TOKEN.

<file name=".github/workflows/publish.yml">

<violation number="1" location=".github/workflows/publish.yml:10">
P2: The tag pattern `v*` triggers this workflow, but nothing verifies that the tag matches `package.json`'s version before `pnpm publish` runs. A stray or mistyped tag could publish the wrong version. Add a step that checks `github.ref_name` against the package version before installing/publishing, e.g. `test "${TAG_VERSION#v}" = "$(jq -er '.version' package.json)"`.</violation>

<violation number="2" location=".github/workflows/publish.yml:25">
P1: `pnpm install` will fail in this workflow because the project depends on `chains` via `file:../chains`, but the job only checks out this repository. Add a step that provides `../chains` (for example a second checkout path) or replace that dependency with a resolvable registry/workspace source before install.</violation>

<violation number="3" location=".github/workflows/publish.yml:27">
P2: This trusted-publishing flow may not actually obtain an OIDC token. `actions/setup-node` with `registry-url` writes `//registry.npmjs.org/:_authToken=${NODE_AUTH_TOKEN}` into the runner's `.npmrc`; with no `NODE_AUTH_TOKEN` secret the placeholder expands to an empty string, npm treats auth as already configured and skips the OIDC exchange, failing with `ENEEDAUTH`/`E404` (see npm/documentation#1960). Users also report `pnpm publish` does not trigger OIDC while plain `npm publish` does, and npm 11.5.1+ is the minimum for trusted publishing. Verify the publish actually authenticates via OIDC, and prefer `npm publish` with the empty auth line removed (or an explicit OIDC-derived token) instead of relying on the setup-node-generated `.npmrc`.</violation>

<violation number="4" location=".github/workflows/publish.yml:27">
P1: This workflow runs on tag pushes, which leave the checkout in a detached HEAD state. `pnpm publish` performs a git branch check by default and fails with `ERR_PNPM_GIT_UNKNOWN_BRANCH` in that state, per pnpm's known behavior with detached HEAD tag checkouts. Add `--no-git-checks` to the publish step or set `gitChecks: false` in `pnpm-workspace.yaml`.</violation>
