A lot of us on alloy wheels are riding rims with a big crack. The ends of the extrusion are just kept aligned with pins and spoke tension keeps the ends from separating.
If this were my rim, I'd just ride it until it gets to the point where it obviously needs to be trashed. If someone that knows about repairing carbon rims were to suggest removing any loose resin and put a coat of new resin over that spot, then I'd think that reasonable.
I'd wait till I found out from someone that works on carbon rims before doing much of anything. Except maybe ride it. Maybe not down the twistiest of roads at my highest speeds.
