  # ── Dedicated benchmark gate ─────────────────────────────────────
  # The cross-language `*-pipeline-benchmark.test.ts` suites are gated behind
  # GITNEXUS_BENCH (they generate synthetic codebases at scale), so the main
  # coverage job above SKIPS them — their O(n^2) scaling guards never ran in CI.
  # Run them here with GITNEXUS_BENCH=1, alongside the Python scope-capture and
  # import-resolution fingerprint + scaling guards (PR #1918 P2a).
  #
  # `--no-file-parallelism` is REQUIRED: these suites measure wall-clock and peak
  # heap, so parallel forks both skew the timings and OOM the worker pool — they
  # must run one file at a time.
  #
  # go-pipeline-benchmark.test.ts is deliberately NOT included: its
  # worker-pool (#1848) suite spins a real worker pool that exits unexpectedly
  # under vitest's fork pool (reproduced in validation), which would make this
  # gate flaky. Go is already guarded by its non-gated O(n^2) tripwire (runs in
  # the main coverage job) plus its golden capture-parity test.
