Real harness Machine QA
This source-maintainer procedure is documented in the upstream source guide.
For project QA, use yoke qa plan run --plan PLAN --project P; read its --help for candidate and machine bindings.
Machine QA execution contracts carry public_ref and
deployment_member_public_ref for item subjects. The engine composes those
refs through the issuance transaction before sealing the case target and
execution digests; clients reject
internal item fields and incomplete refs.
