App 2.40.3: the signal recorder listens to the assistance properties

Browse Source 
The ACC recording of 2.32.0 only polled, and the AAD_* properties read
their defaults. The head unit's own assistance manager never polls them:
it subscribes to each for change events, and a vendor HAL may fill a
value only while someone listens. EVHardware gains a read-only
listenToProperties and AssistBlock (global vendor properties 0x21x0A1xx,
all 108 AAD_* ids); the recorder subscribes to that block for its three
minutes and lists the properties heard, those with changing values first.
