# host-on-sx conformance runner — loads the kernel stdlib, the subsystem
# libraries the host wires to, the host modules, and the host test suites in one
# sx_server process, then reports pass/fail per suite. Mirrors lib/dream's runner.
#
# Usage:
#   bash lib/host/conformance.sh        # run all suites
#   bash lib/host/conformance.sh -v     # verbose (list each suite)
