GC: For a, there is coherent majority attestation with a broad range of A-related witnesses at the top.
TP: As a rule, the superordinate noun and the genitive either have an article or are both anarthrous, unless the genitive is a proper name. Both variants must be grammatically sound because κύριος is frequently used as a proper name.[1] It is more likely that τήν was accidentally omitted after a similarly sounding ending of the preceding word, rather than being a secondary addition.
