+## Source inventory, evolution and local questions
+
+The Sources workspace starts with a compact inventory of loaded themes and
+their real observation ranges. A collapsed follow-up catalogue distinguishes
+official sources that exist from datasets that are already persisted in the
+active project.
+
+Evolution mode compares the exact selected persisted Area when the full
+municipality/region action is used. It shows the selected before/after values,
+all compatible supporting metrics and a chart/table for every observation in
+the same source series. It never merges GRB current geometry with a differently
+measured historical land-use series.
+
+`AI-vragen` is a separate local Ollama workspace. Users select one of the
+models actually installed on the server, ask about the active Area or drawn
+rectangle and can inspect how many metrics, time series and source datasets
+were supplied. Chat history remains in the browser session; source measurements
+are recomputed by the backend from PostGIS for every question.
