Proposed resolution (approved by CWG 2026-02-20):

Change in 11.7.3 [class.virtual] paragraph 18 as follows:

A class with a consteval an immediate virtual function that overrides a non-immediate virtual function that is not consteval shall have consteval-only type (6.9.1 [basic.types.general]). A consteval An immediate virtual function shall not be overridden by a non-immediate virtual function that is not consteval.

Subclause 11.7.3 [class.virtual] paragraph 18 disallows mixing consteval and non-consteval virtual function overrides. This does not cover immediate functions via escalation.
