  # Run push CI only on the default branch. A branch that lives in this repo
  # fires both a `push` and a `pull_request` event for the same commit, and
  # both runs report the `TS CI / Success` context to that commit. Branch
  # protection then sees two results for the required check, so a cancellation
  # or flake on the push side (e.g. two pushes racing on the test.yml
  # concurrency group) blocks the PR even when the pull_request run passed.
  # Restricting push to `main` means PRs carry `TS CI / Success` only via
  # their `pull_request` run (and the merge queue via `merge_group`); `main`
  # is validated pre-merge by `merge_group` and re-checked post-merge here.

  # Single aggregate gate — the only TS CI context branch protection needs

  # work: they skip on non-TypeScript PRs, and a matrix job skipped at the
  # job level never expands its `${{ matrix.* }}` name, so the per-platform
  # contexts it would report never appear and the PR blocks forever waiting
  # for them. This job always runs (it reports under a static name in every
  # state) and fails only if a dependency actually failed or was cancelled —
  # skipped dependencies count as a pass.
