Audio paths the allocated buses draw: every summing bus + main, excluding DCA — a DCA is
control-domain coupling and carries no audio. The ONE spelling of the bus-path sum, derived
from BUS_TYPES; totalAudioPaths, the profile's pool budget and the schema's
pool check all read it, so a new bus type is counted the day its table entry lands.
