# Secondary-SDR Container — node-26#9
#
# Claims the node's SECOND physical SDR (the first is always op25's). Mode is
# chosen at runtime via the control API, not baked in: dump1090 for ADS-B,
# AIS-catcher for AIS (op25_2 mode is not handled here yet — see node-26#9).
#
# Device claiming is by RTL-SDR index, not serial (op25's DeviceConfig.args
# has no serial concept either — see op25-container/app/models.py). Index 0
# is reserved for op25; this container always addresses index 1. That's a
# real limitation once serial-stable device binding matters (hot-unplug /
# replug can swap indices) — tracked in node-26#9, not fixed here.
#
# UNVERIFIED: this image has not been built or run against real hardware in
# this session (sandboxed authoring machine, no docker). dump1090 and
# AIS-catcher's exact CLI flags below are believed correct from their
# published docs but not confirmed against a real capture — the CTO/QA
# review before this ships to a real node should build and smoke-test it.
