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.
