# One-shot: builds everything, starts sensing-server + bridge + presence
# injector under a single process group, opens both UIs, waits for Ctrl-C,
# and kills all three children cleanly. The sensing-server is run with
# cwd=v2/ so its default --ui-path of ../ui resolves; the bridge stays in
# this directory so ./mac_wifi works.
#
# --source esp32 is required: the server's "auto" probe only binds UDP if it
# detects frames *before* the bridge starts sending. The bridge IS the ESP32
# source (synthetic, but same wire format), so pin it explicitly. Otherwise
# the server falls back to `simulate`, never binds UDP, and you get
# ECONNREFUSED on the bridge + a UI showing simulated (fake) motion.
#
# presence_to_pose.py is required for the 3D Observatory: the sensing-server
# computes motion stats from CSI frames, but rendering a single coherent
# figure (instead of the placeholder five-skeleton fallback) needs an
# explicit POST to /api/v1/pose/external. The script polls the bridge's
# /aps endpoint and translates per-AP RSSI variance into one honest pose.
