…what? Where do you see the claim that they are running a mesh? Why would they do that?

The main point of inter-satellite links is to provide coverage to areas beyond single-hop (subscriber to satellite to ground station) coverage. (Theoretically they can also be used to provide extremely low latency intercontinental routing, but for most traffic, the goal would be to minimize routing in space.)

Since the entire constellation is known a priori, all paths can be precomputed centrally, just like in a non-moving network, and that routing information can then be propagated to terminals and satellites. There’s no need to dynamically make complex “mesh” routing decisions at the edge.

802.11r controls faster key exchanges in 802.11 roaming scenarios – what’s the relation to satellite ISPs?

It seems like you have some axe to grind with Starlink and are collecting evidence through that lens.
