Isn't a wheel brow a spec part? How would that part be damaged, isn't the most likely culprit heat?
Could just be the joint to the upright itself, vibrating more than they expected, etc, there's quite a sharp radius there - you saw them drilling out the crack there the first day on the TV. Little too much stress there at a guess. They did mention over the winter the new front tyre deforming slightly differently than originally expected, so maybe they have a little bit of resonance.
Can't see it needing much more than actually completely removing, grinding out and rebuilding with a couple of extra layers of carbon tape. Might even find they just bond a titanium stiffener in there for next week temporarily, easy fix.
