    "Exploratory model-output analysis, not a surf-session observation study or climatology.",
    "Only 108 breaks contain all 75 possible dates; late-window coverage declines sharply.",
    "The historical aggregation path did not include tide-series scoring.",
    "The historical path used arithmetic direction averages and daily-max period selection, unlike the current live path.",
    "The upstream Open-Meteo model selection was not pinned in the stored row provenance.",
    "Nearby breaks and consecutive days are not statistically independent."
