The archive co-attestor.

sh_WORM co-attests the write-once-read-many archive — the retention posture designed to support court-admissible evidence handling under FRE 902(13)/(14), and SEC 17a-4(f) for FINRA-regulated buyers.

Where sh_E asserts, sh_WORM archives. The two roles are reciprocal and cross-attest each other under the Operating Agreement.
