Registration: a concrete element type of an object list that is not keyed, and [MessagePackFormatter] on any type or member on the id path or on the id member, are refused. The id path is a fixed point over the walk's edges. The codec refuses, once per document type and on every encode and decode path, a resolver ahead of StandardResolver that formats a type on that path. UnionArmGuardTests moves StubArm out of the list union. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
