Explicit parser frequencies made canValid=False when state-dependent
messages are absent (PCM_BUTTONS is event-driven; MPC_LKAS_CMD/ACC_CMD
only flow when stock ADAS is active), tripping EventName.canError.
- Alive-check only control-critical messages, at a conservative 10Hz
(1s timeout): ESC, BRAKE_APPLIED, PEDAL, STEER_MODULE, STEERING_TORQUE,
DRIVE_STATE, ACC_HUD_ADAS
- Parse-but-don't-alive-check (nan) the rest: STALKS, METER_CLUSTER,
MPC_LKAS_CMD, ACC_CMD
- PCM_BUTTONS is parsed on both pt and cam parsers (bus assignment is
harness dependent); MADS reads LKAS_ON_BTN from whichever bus sees it
Verified: canValid=True with idle stock ADAS, LKAS button events work
from either bus, canValid stays True throughout.
Copying the tree to a device with scp/file managers mangles symlinks
(car_list.json et al become text files containing the target path),
crashing the UI with JSONDecodeError. This script deploys via
'git archive HEAD | ssh tar -x', which preserves symlinks, verifies
them on-device, and keeps the previous install for rollback.
