Source attribution does not imply endorsement of MetOry.
Source organisations provide underlying public and scientific data. MetOry is an independent value-added service and is not endorsed by the source organisations.
Direct provider artefacts are retained with provenance. Open-Meteo remains a distributor in the operations panel, not a substitute lineage claim.
Foundational decode includes canonical air_temperature_2m. Native grids are preserved. Fusion is not implemented.
SHA-256 integrity, immutable raw storage, and no silent rewrite of source artefacts.
Official warnings stay official. MetOry advisory is a separate object. Missing warning-source data is not “no warning”.
Agreement scoring is not a live public capability. Equal valid time is not comparability. A gust 3/3 claim is not shown. PLANNED Model agreement is not probability.
