# bootstrap:start/3 is the one-call kernel bring-up: starts the
# registry gen_server, populates it from the genesis bundle,
# and starts the nx_kernel gen_server. Each test inlines the
# start call with downstream operations because spawned
# processes don't survive across separate erlang-eval-ast calls.
# 11 cases.
