Change aclpub2 to flag missing ORCIDs?

这个 Issue 没有描述。

The issue names the aclpub2 entry point but provides no file, test, or implementation details. Locate aclpub2 and inspect how it currently validates or reports ORCID metadata; done means missing ORCIDs are clearly flagged, with the relevant existing checks or tests passing.
