# The merge check of the node-engine (novox/hq to-be 45 §9), run by the build seat on every pull request
# before it merges, beside the controller the mesh runs and the facts snapshot the controller keeps.
#
#   1. formatted, vetted, and the whole suite;
#   2. the merge gate **with this change's validator**: the controller the mesh runs is built with the
#      validator from this tree in place of the one it vendors, and every machine of the snapshot is
#      composed and validated by it. A change to the node-engine that would refuse what the mesh sends
#      today fails here, naming the machine — not on the first machine it reaches.
