      # Both `obikmer` and `obikindex` default to the `numa` feature
      # (hwloc-based topology detection + CPU pinning), which is only useful
      # on bare-metal multi-socket indexing hosts. Under this runner's
      # container/cgroup setup it deadlocks at startup — confirmed live
      # (2026-08-11): the same test binary hangs indefinitely with `numa` on
      # and passes instantly, repeatedly, with it off, on the same
      # container. Disable it for CI; it has nothing to do with test
      # correctness.
