  # Why: a README/docs-only PR used to start the full matrix (test shards,
  # two package jobs, typecheck, git compat, xterm, shell contracts). Path
  # filters on `on.pull_request` would drop the `verify` check entirely; this
  # detector keeps verify as the required aggregate and skips the expensive jobs.
  # Per-job outputs also skip git-compat/xterm/packaging/shell when those
  # inputs are unchanged; empty diffs fail closed and run everything.

  # Why this is not in verify's needs: it is the first PR-gate run of a harness whose reliability
  # is only known from nightly main runs (20/20 green, 2026-08-09..2026-08-29, p50 3m25s). It
  # reports a red X on the PR without blocking, exactly like `e2e` above. Deliberately no
  # continue-on-error: that renders the check green and hides the signal it exists to give. To
  # make it blocking, add it to verify.needs, add TERMINAL_IME_NATIVE to the env below, and
  # require `success || skipped` outside the strict loop — see the note on `e2e`.

      # Why: e2e is deliberately absent from needs. The suite is currently red on
      # main (every scheduled run), so gating merges on it would block any PR that
      # touches tests/e2e/** — including the ones fixing the suite. Until it is
      # green the job runs and reports for E2E-path PRs without blocking. To flip
      # it on: add `e2e` to needs, add E2E to the env below, and require
      # `"$E2E" = success || skipped` after the loop — skipped is the normal
      # result for a path-filtered job and must keep passing, so it has to be
      # checked outside the loop or it would excuse the jobs above.
