rose-ash/lib/host/serve.sh

#!/usr/bin/env bash
# host-on-sx live server launcher. Loads the kernel stdlib, the subsystem
# libraries, and the host modules into one sx_server process, then calls
# (host/serve PORT ...) which binds the native http-listen server to the
# Dream-shaped host app. Runs in the FOREGROUND (http-listen blocks), so this
# doubles as a container entrypoint and a local launcher.
#
# Usage:
#   bash lib/host/serve.sh                 # serve on $HOST_PORT (default 8910)
#   HOST_PORT=8920 bash lib/host/serve.sh  # pick a port
#
# The module list is kept identical to lib/host/conformance.sh so what serves is
# exactly what the suites verify.

set -uo pipefail
# Project root: SX_PROJECT_DIR in containers (set to /app by the compose stack),
# else the git toplevel for local runs.
