[3-LEG] Local three-leg environment chain, one location (?loc=): leading air quality (AQI) -> current precipitation, rain and 30-day dry-wet -> realized nearest river stage and streamflow (confirmation gate). A sequential chain, not one reading - confidence = how many legs are lit, in order. Sources: EPA/CAMS, ERA5, USGS. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed.Overview
