Fixes node-26#11. OP25's generated config said "rtl" (= whichever dongle
enumerates first), so on 2-SDR nodes a decoder could take OP25's dongle
and stop recording. Now:
- sdr_pins: {op25|adsb|ais: serial}, absent = automatic. Every OP25
config generation (op25_client.generate_config) rewrites the device to
rtl=<serial>: the pin, else the first dongle's serial, which is what
"rtl" always opened. Left as "rtl" only for unknown/shared serials.
- secondary-sdr: /secondary/devices lists dongles + serials via librtlsdr
(works while claimed). apply(priority, pins, reserved) never touches
OP25's dongle, gives a pinned service only its own dongle, lets a
higher-priority service take a spare from a lower one, and still runs a
pinned lower-priority service when the top pick has no dongle.
- sdr_settings.py replaces secondary_priority.py: one apply path for the
local dashboard, the new set_sdr_config C2 command (set_secondary_priority
kept as an alias) and config pushes. OP25 restarts only when its own
dongle changes. Checkin reports sdr_devices, sdr_pins, op25_sdr_serial.
- Local dashboard: 'SDRs' card with an OP25 SDR dropdown and a per-service
dongle dropdown, duplicate-serial and double-pin warnings.
Verified: edge-node pytest 194 passed; secondary-sdr tests 7 passed;
flake8 clean; page JS passes node --check.

Replaces the single secondary_sdr_mode with secondary_sdr_priority, e.g.
["adsb", "ais"]. OP25 always keeps its own dongle; the secondary-sdr
container starts decoders top-down until it runs out of free SDRs, so a
3-SDR node runs ADS-B and AIS at once and a 2-SDR node runs the top pick.
- secondary-sdr: one decoder per mode, POST /secondary/apply(priority)
(no-op when the right prefix is already running), orphaned decoders
from a uvicorn reload are reaped on start, /status reports sdr_count
via lsusb (op25's :stable image has none).
- edge-node: one apply path (set_secondary_priority) for the local
dashboard, a new C2 'set_secondary_priority' MQTT command, and config
pushes; it never restarts op25. Legacy mode migrates on load. Checkin
reports priority, what's running, and sdr_count. Uplink forwards
aircraft and vessels whenever either is present.
- Local dashboard: 'Secondary SDRs' card to enable/reorder/save.
Verified: edge-node pytest 190 passed, flake8 clean.

node-26#9. New secondary-sdr-container claims the node's SECOND physical
SDR (RTL-SDR index 1 — op25 always claims index 0; no serial-based binding
yet, same gap op25 itself has). Its control API (start/stop/status/data,
mirroring op25_controller.py) launches dump1090 in adsb mode and exposes
the decoded aircraft.json snapshot; AIS mode 400s until it's wired next.
edge-node: on_config_push starts/stops it when secondary_sdr_mode changes,
lifespan resumes it after a restart if already configured, and a new
telemetry_uplink_loop polls its /secondary/data every 10s and POSTs
non-empty snapshots to C2's new /telemetry/adsb (same bearer-key pattern
call_recorder.py already uses for audio upload).
UNVERIFIED: this container has not been built or run against real hardware
in this session (sandboxed authoring machine, no docker) — dump1090's
--write-json field names are believed correct from its docs but not
confirmed against a real capture. Build + hardware smoke test before this
reaches a real node.
