  # Temporary parallel job: builds the new nim-ffi library (cbind/libp2p_ffi.nim)
  # and generates its C/CDDL bindings. Folded into the main flow at the flip PR,
  # when libp2p_ffi.nim replaces the legacy libp2p.nim.
  #
  # Disabled until the final PR of the nim-ffi migration series: libp2p_ffi.nim is
  # built up incrementally across PRs 2..9 and only compiles end-to-end at the
  # flip. Re-enable (drop `if: false`) once the library is complete and expected
  # to pass.
