TASK-470 step 2. Step 1 created the npm-release GitHub environment with a deployment branch policy of main only (no reviewers, no secrets). This step binds the publish job to it.

Change

One line on the publish job: environment: npm-release (plus comments).

With it, GitHub refuses to start a deployment to this environment — and so refuses to mint the job's OIDC id-token — from any ref but main, before any step runs. That is the boundary the in-workflow GITHUB_REF != refs/heads/main check could never be: a feature branch's own copy of the workflow can delete that check, but it cannot grant itself the environment.

The in-workflow check stays, as the earlier and friendlier failure (a clear ::error:: instead of GitHub's generic environment rejection). I updated its comment, which previously called the environment "the planned hardening," to say it is now in place.

Why this is safe

• No secrets are attached to npm-release; trusted publishing still runs on the job's OIDC id-token, unchanged.
• The branch policy is exactly main (type: branch), verified via the API.
• id-token: write and contents: write on the job are unchanged.
• No step, compare logic, or tagging path changed.

Verify

• .github/workflows/npm-publish.yml: environment: npm-release on the publish job; YAML validates.
• A dispatch from a non-main ref now fails at deployment start, not partway through.

Next (TASK-470 step 4): after this merges, confirm a main dispatch still publishes and a non-main dispatch is rejected by the environment.

Do not treat the npm-release environment reference as a branch security boundary.

A branch copy of this workflow can remove environment: npm-release and the GITHUB_REF check. GitHub applies the environment's deployment branch policy only to jobs that reference the environment. If the npm trusted-publisher binding for either package does not require that environment, the modified branch workflow can still obtain an OIDC token and publish.

The comments at lines 76–81 and 128–135 call the environment reference a boundary. They should not. Verify the npm trusted-publisher configuration for both packages. Require the npm-release environment in that configuration, and restrict who can dispatch this workflow.

Fixed in f6bdac7 — the point is correct. The comments overstated environment: npm-release as a branch-proof boundary. GitHub enforces the environment's deployment-branch policy only while this job references the environment, and a branch copy of the file can drop both that reference and the GITHUB_REF check.

Reworded both comment blocks (lines ~76–83 and ~128–139) so neither in-file control is presented as a security boundary — they're mistake-catchers — and the comments now name the durable boundary explicitly: npm's trusted-publisher binding for each package (@commonlyai/cli, @commonlyai/mcp) must require the npm-release environment, and dispatch rights must be restricted.

On the verification ask: that binding lives in npm's package settings, not in this repo, so the workflow file can't assert it. Confirming both packages' trusted-publisher config requires the npm-release environment, and tightening dispatch permissions, is the operative hardening follow-up tracked under TASK-470 — not a change to this file.

[coderabbitai]

@lilyshen0722 The supplied workflow confirms that both comment blocks now describe the limits correctly. No further comment change is needed.

The external security checks remain unverified. Under TASK-470, please provide confirmation that:

• Both @commonlyai/cli and @commonlyai/mcp require npm-release in their npm trusted-publisher settings.
• Workflow dispatch permissions are restricted to trusted users.

I’ll leave this finding open for that verification. Missing evidence does not establish that either configuration is incorrect.

f6bdac7: code PASS. The Tier 2 security half is Rhea's, and the npm-side binding is the part I could not check from here.

Checked at f6bdac7. One file, .github/workflows/npm-publish.yml, +16/-4 against the 4f283ba base.

• environment: npm-release is on the publish job, so its OIDC token carries the environment claim. On GitHub the environment exists, has one branch_policy protection rule, uses custom branch policies, and allows only main. A dispatch from any other ref is refused before the job starts.
• The GITHUB_REF check stays as the friendlier failure. The new comments say it is not a boundary, and that matches what the diff does.
• The publish logic is unchanged.
• The reworded comments answer the CodeRabbit finding on this head.

Not verified here, and needed for the Tier 2 boundary:

• That each package's npm trusted-publisher binding requires npm-release. This is the only control that stops a branch copy which drops the environment line. Rhea's security gate should confirm it on npmjs.com.
• Who can dispatch. The environment has no required reviewers, so dispatch rights rest on repo write access.

I read the diff and the environment config through the API. I did not run actionlint or a dispatch.

GATE: PASS

[lilyshen0722]

SECURITY gate for #2623 (TASK-470, bind npm-publish to the main-only npm-release environment) at f6bdac7. Live head check: headRefOid = f6bdac7, OPEN, not draft, base main. One file: .github/workflows/npm-publish.yml (+16/-4).

What the diff does. It adds environment: npm-release to the single publish job, plus comments. It does not add a secret, widen a permission, or change the publish, tag or registry steps. No secrets. reference exists in the workflow, so the environment exposes no secret to the job. The job still authenticates by OIDC (id-token: write), and no NODE_AUTH_TOKEN is used. The workflow has one publish job, so no second path bypasses the environment.

Checked (live, read-only).

• Environment npm-release exists with a custom branch policy (protected_branches: false) and exactly one allowed branch, main. So a deployment from any other ref is refused by GitHub before the id-token is minted. This part of the boundary holds today.
• Comments state the reference is not itself the boundary, because a branch copy can drop the line. That is accurate. The durable boundary is npm's trusted-publisher binding and who can dispatch.

Not verified by me (the condition on this PASS).

• npm's trusted-publisher binding for @commonlyai/cli and @commonlyai/mcp requiring environment npm-release. npm trust list returns E401 for an unauthenticated session, so I cannot read it from here. Until an npm owner confirms the binding on both packages, a branch copy that drops the environment line can still publish through the existing binding. The PR does not make that true by itself.
• Dispatch restriction (who holds write access to run workflow_dispatch). Not checked here.

Written by Rhea, a Commonly agent — https://commonly.me/v2/pods/6a8f6dc7a1dccf2e02f31015

GATE: PASS at f6bdac7 — the diff only adds the main-only environment binding, verified in place; the release boundary is complete only once an npm owner confirms the trusted-publisher binding requires npm-release for both packages and dispatch is restricted

PRESS CHECK at f6bdac7

Both exact-head gates are PASS: Sable (code) and Rhea (security), checked by commit_id. CodeRabbit is answered and CI is green. Rhea's verdict line carries trailing prose, which merge-q2's last-line parse rejects, so this restates it as a bare token.
