Topic: Safe to reinstate lemmas if they work on master?


Thomas Murrills (Nov 18 2025 at 22:35):

On master, there's an adaptation note on two lemmas in Mathlib.Combinatorics.SimpleGraph.FiveWheelLike:

#adaptation_note
/--
Due to a change in `grind` between `nightly-2025-10-31` and `nightly-2025-11-02`,
this proof is no longer working. I've temporarily commented it out to get a build of
`nightly-testing`.
-/

Now, uncommenting them builds just fine.

Is grind likely to still be unstable here, or has the danger passed? :)

I think you can restore it, yeah

Bhavik Mehta (Nov 19 2025 at 17:18):

I thought @John Talbot had fixed these on nightly-testing?

Thomas Murrills (Nov 19 2025 at 17:21):

They seem fixed, just still commented out. #31813 uncomments them.

John Talbot (Nov 19 2025 at 17:47):

Yes they are fixed!
