# Run the link-wire-spec conformance harness against the candidate binary
# (adapted from the spec repo's conformance/example-candidate-ci.yml).
#
# The spec repo — and the GPL reference it builds — live only in the
# runner's temp directory and caches, never in this repo's tree or
# artifacts (clean-room firewall; see PROVENANCE.md). The job output is
# observations only.

  # tempo driving). Move this pin to a release tag once one exists
  # (link-wire-spec issue #4) and the branch is merged.
