  "changeNotes": [
    "Expanded from the five-city pilot to approved named prices in every U.S. state and Washington, DC.",
    "Added nine published city guides and 27 exact-branch restaurant profiles to fill the missing state-market guide coverage.",
    "Collected official source outcomes across the existing U.S. city-shortlist panel, retaining unresolved sources and candidates.",
    "Added state, Census region, division and postal-place fields; suburbs are not silently counted under a parent guide\u2019s city.",
    "Separated main dishes from starter, side, sharing, children\u2019s, delivery and package examples; portions and source-check dates remain visible.",
    "Added payment-dependent charges and more verified regular coffee observations while preserving unknown terms and unresolved charge stacking.",
    "Preserved the original 52-row baseline and the five-city pilot as immutable earlier versions. The larger sample is not a time-series price change."
