The candidate list itself lives in an at.atjam.playlist of at.eptss.track records — this record pins that playlist by CID and adds only what a playlist must never carry: round attribution and who nominated what. Ballots strong-ref this ledger, so the pin chain runs ballot → ledger → playlist → tracks, and a post-hoc edit anywhere is detectable. Attribution keys on the track's AT-URI, never on its position — a positional array desyncs silently on one reorder. The organizer honors un-naming requests by editing nominations in place."
