Results provide a clear status \u2014 CLEAR, WATCH, AT RISK, CRITICAL, or NO DATA \u2014 with the reason, key measurements, and supporting evidence.\r\n\r\n**What's new since 1.1.4**\r\n\r\n- **United States data:** Explore FCC ULS microwave links in the current map view using the guided USA Data Setup workflow. The USA data pack is separate and is not bundled with the plugin. Canadian data remains available without it.\r\n- **Canadian antenna heights:** Uses licensee-reported ISED antenna-height data instead of assuming 30 m for every endpoint. US antenna heights remain 30 m and are explicitly labelled Assumed.\r\n- **Rain attenuation:** Uses ITU-R P.838-3 rain coefficients and correctly converts Open-Meteo's 15-minute precipitation totals to hourly rates. Snow, freezing precipitation, and mixed precipitation are presented separately rather than counted as rain.\r\n- **Clearer analysis:** Summary, Details, and Evidence views; baseline-based change comparisons; and rule-based Ask answers grounded in the current result.\r\n- **Data provenance:** Values are labelled Observed, Model-derived, Calculated, Inferred, or Assumed. Excel and CSV exports include data-source information, product and library versions, and the earth-curvature convention.\r\n- **Interface improvements:** Zoom-dependent map-cluster fading, authorization numbers in link titles, configurable Records table columns, and improved layouts for narrow panels.\r\n\r\n**Important limitations**\r\n\r\nResults are model-based engineering estimates for investigation, not outage predictions. Calculations use the published `aei-link-clearance` and `aei-microwave-link-exposure` libraries. Install the required dependencies listed in `requirements.txt`.
