+# Pass 03 — Database and Domain Foundation
+
+## Goal
+
+Add the PostGIS-ready database/domain foundation.
+
+## Implement
+
+- SQLAlchemy database setup.
+- Alembic migration setup.
+- Core models: Project, Area, Dataset, AnalysisRun, Export.
+- Pydantic schemas matching API contract style.
+- Geometry handling strategy ready for PostGIS.
+
+## Constraints
+
+- Do not store geometry as arbitrary strings in final domain models.
+- If test environment cannot run PostGIS, isolate integration tests and keep unit tests safe.
+- Do not remove future raster/AI fields because V1 starts smaller.
+
+## Validation
+
+- Backend imports.
+- Model metadata initializes.
+- Migration command documented or executed if environment allows.
+- Unit tests pass.
+
+## Acceptance
+
+- Domain model can support project -> area -> dataset -> analysis.
+- Geometry metadata and CRS are represented.
+- Execution log updated.
