# Codex Phase 1 Prompt — Backend Foundation

You are working in the GeoIntel Kempen repository.

Read these files first:

1. `docs/PRODUCT_BLUEPRINT.md`
2. `docs/DEVELOPMENT_RULES.md`
3. `docs/DATABASE_SCHEMA.md`
4. `docs/API_SPECIFICATION.md`
5. `docs/STORAGE_ARCHITECTURE.md`
6. `docs/IMPLEMENTATION_BACKLOG.md`

## Mission

Build the backend foundation for GeoIntel Kempen without implementing fake features.

## Required output

- FastAPI backend skeleton.
- Config/settings module.
- Database connection to PostgreSQL/PostGIS.
- Initial models for projects, areas, datasets, layers, analysis runs, metrics, exports and jobs.
- Alembic migrations if applicable.
- Health endpoint.
- Basic project/area/dataset CRUD endpoints where safe.
- File storage service skeleton with real path handling.
- Tests for config, health and core models where feasible.

## Non-negotiable rules

- Do not fake GIS processing.
- Do not create endpoints that pretend analysis was completed.
- Every geometry field must be designed for PostGIS.
- Every dataset must support metadata.
- Keep code modular.
- Update TODO/backlog after changes.

## Delivery format

At the end, report:

- Files changed.
- What works.
- How to run.
- Tests run.
- Remaining tasks.
