+# Domain Model Contract
+
+## Core aggregates
+
+### Project
+A project is an investigation workspace. It contains areas, datasets, analyses, and exports.
+
+### Area
+A spatial polygon or selected administrative unit used to clip and analyze datasets.
+
+### Dataset
+A source artifact or external reference. Datasets can be raster, vector, reference, model output, mask, or export.
+
+### AnalysisRun
+A tracked execution of a pipeline such as detection, segmentation, QA, clipping, tiling, or index computation.
+
+### Detection
+A model-derived feature, usually a georeferenced bounding box or polygon.
+
+### Segmentation
+A mask-derived polygon or raster mask output.
+
+### QualityCheck
+A comparison between model outputs and reference data such as GRB.
+
+## Geometry rules
+
+- Use SRID 4326 for API-level GeoJSON interchange unless explicitly documented.
+- Use projected CRS for area/length calculations when required.
+- Store original CRS metadata for every dataset.
+- Never calculate area in degrees.
