- Around line 7-12: Move the candidate_npmrc check from
ci-install-dependencies.sh to execute before actions/setup-node configures
registry-url, or relocate npm configuration outside the workspace so the
generated .npmrc is not mistaken for a repository file; preserve rejection of
pre-existing repository .npmrc files during trusted dependency installation.

In `@test/automation/pull-requests/pr-workflow-contract.test.ts`:
- Around line 376-381: Update the permissions assertion in the pull-request
workflow contract test to inspect every job defining permissions.packages,
retaining each job name and permission value rather than filtering only "read"
entries. Assert the complete expected job-to-permission mapping so any
unexpected "write" or other value causes the contract to fail.

Security review of commit under review 6d16a8a

Verdict

FAIL — this PR must not merge until the two credential trust-boundary findings are resolved. The change gives pull-request-controlled workflow code a token with package access. It also lets pull-request-controlled dependency graphs select packages during the credentialed install.

Blocking findings

1. The pull_request workflow exposes package credentials to pull-request-controlled workflow code.

   .github/workflows/pr.yaml:132, :165, :263, and :401 grant packages: read to four jobs. GitHub evaluates a pull_request workflow from the PR merge commit, so a contributor can change the workflow definition and use ${{ github.token }}. Checking out the composite actions from the base SHA does not protect the workflow definition.

   Required change: Fetch the package only from a workflow definition that GitHub loads from the base SHA. Do not execute pull-request-controlled steps or code in a job that has packages: read. Give unprivileged PR jobs only an exact package artifact whose identity and integrity were validated by base-controlled code.

2. The credentialed install accepts pull-request-controlled dependency graphs that the trusted review does not validate.

   .github/actions/ci-install-dependencies.sh:7-14 rejects .npmrc, then runs npm ci for the root and plugin projects. Both lockfiles remain pull-request-controlled. The reviewed npm audit checks only the root graph, omits development dependencies, and runs in a parallel job. It does not guard nemoclaw/package-lock.json. An npm-shrinkwrap.json can also override either package-lock.json.

   Required change: Before npm runs with NODE_AUTH_TOKEN, base-controlled code must reject root and plugin npm-shrinkwrap.json files. It must validate both effective lockfiles, including development dependencies, against the base-controlled exact package allowlist. The install must stop before npm receives credentials when validation fails.

an empty expectedIntegrity. Update scripts/audit-reviewed-npm-graph.mts at lines
366-384 by adding sourceRegistryPackagesWithoutIntegrity to
materializeSourceGraph, passing it as reviewedPackagesWithoutIntegrity, and
forwarding config.sourceRegistryPackagesWithoutIntegrity from auditSourceGraph.

Security re-review of latest PR commit 3f3d3184d

Verdict

FAIL — this PR is not approval-ready. The latest PR commit resolves the two findings from my previous review: pull request jobs no longer receive the package token, and base-controlled code validates both effective lockfiles before npm runs. Two new blockers remain.

Findings

1. The trusted installer cannot locate its verifier from a composite action

GitHub sets GITHUB_ACTION_PATH to a directory such as .github/actions/ci-build-typecheck. The script computes trusted_root with ../.., which produces .github. I reproduced the composite-action invocation locally. It failed before npm ran:

Cannot find module '.../.github/scripts/checks/prepare-ci-npm-install.mts'

Once this implementation becomes base-controlled, all five dependency-install jobs will fail at this boundary. The current tests invoke the script directly and leave GITHUB_ACTION_PATH unset, so they do not exercise the failing path.

2. The package workflow republishes the SDK archive outside the package authorization boundary

The pull_request_target workflow does not inspect whether either PR lockfile uses the SDK. It downloads and uploads the tarball for every matching PR event. GitHub permits signed-in users with repository read access to download workflow artifacts. The PR workflow also grants actions: read to its PR-controlled artifact-transfer job. See Downloading workflow artifacts.

The accepted issue established an exact package and the need for packages: read. It did not establish that untrusted fork contributors may receive the credential-gated archive. If untrusted PR code must consume the SDK, that access consequence needs an accepted security and lifecycle decision.

Category verdicts

Validation

• All 59 targeted tests passed after I reran one cache-blocked test with a writable prek cache.
• git diff --check origin/main...origin/pr/10368 passed.
• A local composite-action invocation reproduced the missing-module failure.

Security re-review of commit 601673614

Verdict

FAIL — not ready for approval. The latest commits resolve the composite-action path bug, isolate the package token, and validate both lockfiles. One authorization blocker remains.

Finding

The trusted workflow is base-controlled and keeps packages:read away from contributor-controlled code. That part is sound. The remaining issue is the authorization boundary after the download: the archive persists as an Actions artifact for one day, and the exact PR and head-SHA filters in .github/workflows/pr.yaml are contributor-controlled. A contributor can remove those filters and query another recent trusted run. The current PR job itself demonstrates that a token with actions:read can download artifacts from another workflow run.

GitHub documents workflow-artifact downloads as available to signed-in users with repository read access: Downloading workflow artifacts.

The same-repository trigger restriction therefore reduces who can cause a new archive to be created, but it does not preserve the SDK package's original authorization once an archive exists. If untrusted fork code must consume the SDK, the package's confidentiality cannot also be preserved through this design; that requires an explicit accepted product and security decision.

Resolved findings

• .github/actions/ci-install-dependencies.sh now derives the repository root from $0, and the composite-action path test covers the real call shape.
• Contributor-controlled PR jobs no longer receive NODE_AUTH_TOKEN or packages:read.
• The trusted preparation path validates the root and plugin lockfiles, includes development dependencies, rejects shrinkwrap files, and enforces the reviewed SDK version, archive URL, and integrity.
• The intended locator denies fork PRs and checks the same-repository PR head. This protects the unchanged workflow path, but it does not authorize access when the PR changes that workflow.

Reviewed latest PR commit 753c1695bbb46d18022f3b2115a302de62aca5cd against base d63f7b037d84d42f9b6132dbccac6c360fab9906. Issue #9872 records the accepted product and artifact-access scope. The exact SDK handoff is base-controlled, retained for one day, and verified by package identity and integrity. Unprivileged PR jobs install without package credentials, and base-controlled code validates both effective lockfiles and rejects shrinkwrap precedence before installation. Current required checks and the trusted external-gateway run pass.

Security review: PASS

• Secrets and credentials: PASS. Package credentials remain in trusted producer and main-branch jobs.
• Input validation and data sanitization: PASS. Exact specs, lockfiles, artifacts, paths, sizes, and archive integrity fail closed.
• Authentication and authorization: PASS. The accepted artifact-access boundary is enforced by base-controlled workflow code.
• Dependencies and third-party libraries: PASS. The SDK version, source, and integrity are exact.
• Error handling and logging: PASS. Failure paths redact credentials and clean temporary npm configuration.
• Cryptography and data protection: PASS. HTTPS and SHA-512 protect the reviewed archive.
• Configuration and security headers: PASS. Job permissions and credential scope are explicit and narrow.
• Security testing: PASS. Workflow-boundary, installer, archive, cache, and trusted live tests cover the changed controls.
• System security: PASS. Candidate code consumes only the verified artifact and cannot select credentialed package downloads.
