Every study shows its data, its method and its limits, and ships the dataset to download.
Every number in a data study is computed by a script from public data. The method sits next to the finding, the dataset ships with the study, and errors are corrected in the open.

Prices and generation for Hungary are fetched from the Energy-Charts API in quarterly chunks and cached unchanged.
One script turns the cached data into every number, chart and table a data study shows, and writes the derived CSV datasets. Writers quote those outputs; they don't calculate figures by hand.
The text is written from the computed outputs and cited sources: answer first, definitions stated, limits stated.
Figures in the text are checked against the script outputs, and every outside fact links to its source.
Each page shows its published and updated dates. When the data is refreshed, the study says so.
