Audience asks whether Geneva Drive keeps the full history of a workflow's states. Julik avoids storing state blobs on the workflow (only breadcrumbs: next step, scheduled time, hero, creation time) — mutability semantics across resumed steps are an endless onion. Meaningful state should live on Rails models; the questioner suggests paper_trail on the hero, which Julik endorses. Geneva Drive already preserves every step_execution as a log record.
