Matched reference
The matched image is the 90° middle-camera reference; the parked vehicle is ~SEP=6.75 m
ahead. ds=match→start sign, de=match→end sign, dz=sign→sign. in-zone needs
dz≥de>(SEP+CAR) & ds≤dz (cond1) or ds<de & dz<de & ds<SEP
(cond2). Because v1 and v2 run the same input + algorithm, any difference comes from the zone
data (sign positions / which sections are active).Full matching diagnostics — v1 & v2 candidate zones
