The earlier 'ground 366 against an actor at 561' reading was taken in BeginPlay, while the
pawn is still at its spawn height and falling - so it described the surface far below a
falling capsule, not a float. That number drove two hand-tuned Z values (561 for the player
start, 342 for the car) on the strength of a measurement taken at the wrong moment.
The probe now runs three seconds after spawn, traces from the capsule's feet rather than the
actor origin, and reports three channels with the actor and component each hits. A
multi-channel probe at spawn showed every channel hitting the same StaticMeshActor at 366,
which is consistent with the falling-pawn explanation rather than with missing sidewalk
collision.
Not yet read back: the last two game runs produced no log output at all, so the settled
numbers are unverified and recorded as such.
