Standalone diagnostic (run on device over SSH, car IGN-ON/engine-off/
parked, openpilot stopped) that sweeps UDS CommunicationControl message
classes on the ADAS DRV ECU (0x730, ECAN) to find a combo that silences
SCC actuation (0x1A0) while leaving the rear-radar BSM verdict (0x1BA)
transmitting. A winner would restore OEM from-behind, lane-filtered blind
spot monitoring under openpilot long via a one-byte change to the disable
command. Does not alter any openpilot code path; only runs when invoked.
Restores the ECU after each combo and sets the panda to SILENT on exit.

The raw SIDE_DETECT_STATE bit lit the mirrors and UI for cars two lanes
over and for far-ahead traffic, because it has no lane discrimination.
Gate it on a front-radar track actually in the adjacent lane (LONG<15m,
1.9<=|LAT|<=5.5m), latched while side-detect stays asserted with a 0.5s
release debounce and 1s track-near memory, computed in carstate so the
UI path, lane-change veto, and mirror/cluster spoof all consume the same
gated signal. card stashes track adjacency from RadarData; fails open to
the raw bit if the stash goes stale. Validated on onelane/twolanes/
trafficonleft/standstillmirror rlogs.
