There was a problem hiding this comment.
Thanks a lot.
Nice catch. Just a small typo in the comment.

PR #898 avoids implicit derived-to-base conversion (use Entity instead of EntityRep) by overloading id with explicit types Entity, codim = 0 and 3, ensuring the correct ids are used for Entity<0> and Entity<3> in CpGrid with LGRs.
To ensure that IDs are correctly handled in all possible refinement scenarios, one of the test cases invokes adapt() in both the global and distributed views, followed by synchronization of cell IDs. This is where the issue with an empty pointMapping_ arose. This PR provides a fix for it.
