  # Stable required-status-check anchor. `unit-tests` is a matrix job gated on
  # change detection, so on non-Python PRs it is skipped and never produces its
  # `unit-tests (current)` context (a job-level skip happens before matrix
  # expansion). This always-running job reports a single context that branch
  # protection can require: it passes when unit-tests succeeded or was skipped,
  # and fails only on a real failure.
