Gary,
Your inspection confirmed my suspicion based on your first post about the wing joiner. If that were me, I would not fly it without significant reinforcement at the outer end of the tube. As shown, I would class it as very unsafe.
Ideally the factory would install an outer 1/8" ply rib that was mechanically interlocked with the bulkheads which would also support the outer end of the wing joiner tube, thereby providing an outboard mechanical up/ down load-bearing capability to complement and react the wing bending loads against the existing inner clamp block.
As that cannot be easily retro fitted, maybe consider adding a hard-wood support block above and below the tube (full-length) that completely fills in the area between the tube and the upper and lower fuselage skins, and then glassing that in with additional carbon. Also, add another mini-bulkhead on the opposite side of the tube to the existing one to help tie the upper and lower fuselage skins together.
