  # Branch protection requires the e2e-* checks, but the `e2e` job above is
  # skipped on PRs that can't access repository secrets -- fork PRs and
  # Dependabot PRs. A job skipped via a job-level `if` never expands its
  # matrix, so the e2e-* check contexts are never created and the required
  # checks sit at "Expected -- Waiting for status to be reported" forever,
  # permanently blocking merge.
  #
  # This bypass reports a green status under the SAME e2e-* check names for
  # exactly those PRs, satisfying branch protection without running the real
  # tests (which need SOCKET_CLI_API_TOKEN). Its `if` is the precise negation
  # of the e2e job's run condition, so the two are mutually exclusive: any
  # given PR runs one or the other, never both, and never neither.
  #
  # Dependency-bump risk on these PRs is still covered by dependency-review.yml's
  # Socket Firewall smoke jobs, which run without repository secrets.
