The workflow-level permissions block sets only contents: read, which disables other default GITHUB_TOKEN scopes. actions/upload-artifact / actions/download-artifact require actions permissions, so the new artifact-based setup is likely to fail with permission errors. Consider adding actions: write for the setup job (upload) and actions: read for the dependent jobs (download), either at workflow level or overridden per job.

Fixed in commit 2396c37. Added actions: write to the setup job (needed for upload-artifact) and actions: read to each of the downstream lint, format-check, build, and test jobs (needed for download-artifact), while keeping the workflow-level default of contents: read.

jobs:
lint:

actions: write

- uses: actions/checkout@v4

- run: npm ci
- run: tar -czf node-modules.tar.gz node_modules
