# Codex Pass 03 — Raster and Vector Foundation

Goal: implement first real geospatial processing utilities.

Implement:

- vector import from GeoJSON fixture
- vector metadata extraction
- geometry validity checks
- raster metadata extraction if Rasterio fixture exists
- service boundaries for raster/vector operations
- tests using fixtures

Acceptance:

- GeoJSON fixture can be imported.
- Bounds and geometry type are calculated.
- CRS metadata is preserved.
