The lab redesign gave only the lab tab the published-history sidebar; the composer page was expected to have it too. /setup/tariff now lists every published version (name or effective date, active badge, currency) on the right; clicking one loads it into the editor as the SEED for the next publish — which always creates a new immutable version (the sidebar hint states this), making "roll back to last month's prices" a two-click republish while the history stays append-only.
