- subscription.0016: prices equal to the Bazaar panel (senior), ai_daily_quota 5/3/3, card features; packs on_sale=False (one paid pack order, user 26, keeps its credits; pack paths stay for that order and for admin). - Quota math in docs/ai-cost-and-guardrails.md: ~77% of a Bazaar sale reaches us; worst case (full quota every day) the assistant costs 23/27/35% of it. - Assistant quota message points to the subscription, not packs. 982 tests green.
