    "package": "Six vouchers, valid for seven days. Prices and values are invented CU, not historical offer terms.",
    "matrix": "Each price row is a separate cohort of package buyers, followed for a full validity period plus 14 days after expiry. Shares sum to 100% within a row. Repurchase means another package purchase within those 14 days.",
    "association": "Usage depth and repurchase are observed together in this example. Self-selection and other user differences can affect the relationship; using two vouchers is not established to cause repeat purchase.",
    "monthly": "Independent May\u2013September 2019 monthly aggregates. Package-purchase counts include repeat purchases and are not unique people. Matrix cohorts are separate from these monthly counts.",
    "economics": "Estimated extra GMV / platform subsidy spend. GMV means gross merchandise value; this is an explicit modeled efficiency measure, not profit ROI or a controlled causal result.",
    "evaluation": "Original work revised a buyer/non-buyer and pre/post evaluation using scoped samples and adjusted order calculations. Those changes do not by themselves establish a randomized counterfactual.",
    "status": "Pricing and product iterations are documented; later user-specific pricing/productization must be scoped separately from proposals. Period comparisons do not isolate a price effect."
