Lean formalization of Mochizuki’s abc proof fails at the same step again

A serious team tried to formalize Mochizuki’s abc proof in Lean and hit the same sticking point that Scholze–Stix identified eight years ago.
The poster says this is a reminder that the proof remains effectively in a superposition of “solved” and “open.” They also note that this kind of work is only possible thanks to newer computational tools such as Lean and mathlib, which make large-scale formal verification in mathematics feasible.
