+# Domain Model
+
+## Project
+
+A project represents a GeoAI investigation. It is not just a folder. It defines the purpose, spatial areas, datasets, analysis runs, and outputs.
+
+Fields:
+
+- id
+- name
+- description
+- region
+- status
+- created_at
+- updated_at
+
+Relationships:
+
+- has many areas
+- has many datasets
+- has many analysis_runs
+- has many exports
+
+## Area
+
+An area is a selected geometry, usually a polygon. It may represent a municipality, manually drawn polygon, bounding box, or uploaded GeoJSON geometry.
+
+Rules:
+
+- Must have valid geometry.
+- Must have a calculated area in square meters.
+- Must keep original input geometry if uploaded.
+- Must be convertible to GeoJSON.
+
+## Dataset
+
+A dataset is any input or derived geospatial artifact.
+
+Dataset types:
+
+- raster
+- vector
+- reference
+- detection_output
+- segmentation_output
+- mask
+- tile_set
+- export
+
+Dataset statuses:
+
+- registered
+- uploaded
+- metadata_extracted
+- processed
+- failed
+
+## AnalysisRun
+
+Tracks execution of a pipeline.
+
+Analysis types:
+
+- raster_metadata
+- raster_clip
+- raster_tile
+- vector_import
+- object_detection
+- segmentation
+- qaqc
+- change_detection
+- export
+
+## Detection
+
+A model-detected object. V1 supports bounding boxes converted into geospatial polygons.
+
+Important fields:
+
+- class_name
+- confidence
+- geometry
+- bbox_pixel
+- bbox_geo
+- source_tile
+- model_id
+
+## QualityCheck
+
+A measured comparison between predicted features and reference features.
+
+Core metrics:
+
+- precision
+- recall
+- f1
+- mean_iou
+- matched_count
+- false_positive_count
+- false_negative_count
