# Codex Prompt — Pass 06 Raster and Vector Metadata

Implement raster and vector metadata extraction.

Use:

- Rasterio for raster metadata
- GeoPandas/Shapely for vector metadata

Required docs:

- docs/RASTER_OPERATIONS_SPEC.md
- docs/VECTOR_OPERATIONS_SPEC.md
- docs/BUILD_TICKETS_M3.md T-008 and T-009
- docs/TEST_CATALOG.md

Acceptance:

- GeoTIFF metadata extraction works for fixtures.
- GeoJSON metadata extraction works for fixtures.
- invalid files produce clear validation errors.
- metadata is persisted to dataset metadata JSON.
- frontend dataset detail page shows extracted metadata.

Do not remove the GIS stack to simplify installation. If local installation is hard, document Docker-first development.
