# Codex Phase 4 Prompt — Raster and Vector Core

Read all M0/M1 docs first. Implement the first real geospatial processing layer.

## Goals

- Raster metadata extraction service.
- Vector metadata extraction service.
- Vector GeoJSON import into PostGIS.
- Area clipping for vector fixtures.
- Building stats analyzer using vector polygons.

## Requirements

- Use Rasterio for raster metadata when available.
- Use GeoPandas/Shapely for vector processing.
- Preserve CRS metadata.
- Return `unsupported_dataset_type` for unsupported files.
- Add tests with small fixtures.

## Done when

- Backend tests pass.
- Project/area/dataset flows still work.
- A vector fixture can be registered/imported and analyzed.
- Docs/log updated.
