// different weights: adopting a creator you already pay for is a per-row
// action, while "you follow this and your roster doesn't show it" only ever
// REPORTS — the operator disables from the Subscriptions row itself.
//
// `fresh` is the field that matters most here. A stale or never-run roster
// returns an empty tracked_not_subscribed list, and the card must say WHY it is
// empty rather than letting it read as "everything is fine".
