# The merge check of the controller (novox/hq to-be 45 §9), run by the build seat on every pull request
# before it merges — and by hand: `MESH_FACTS=facts.json MESH_GATE_POSTGRES=… MESH_TEST_POSTGRES=…
# MESH_TEST_NATS=… sh merge-check.sh`.
#
# The build seat clones this repository with the catalogue and the host beside it (the tests read them
# there), reads the facts snapshot the controller keeps, and raises a throwaway store and bus of the
# versions the mesh runs; this says what is judged with them:
#
#   1. formatted and vetted;
#   2. the merge gate, judged by THIS change's controller: every machine of the snapshot composed with
#      it and validated by the node-engine's own validator, against the mesh as it is;
#   3. the whole suite, the replays among it, against that store and that bus, one package at a time
#      because the live tests share one bus's fixed names.
#
# Fails on the first that fails. The gate's verdict is written where MESH_CHECK_VERDICT says, so the
# pull request is told the gate's own words.
