# Pass 06 — Raster and Vector Metadata Foundation

## Goal

Add first geospatial metadata services.

## Implement

- GeoJSON/vector metadata extraction using GeoPandas/Shapely where available.
- Raster metadata service interface using Rasterio where available.
- Controlled unavailable-state if Rasterio/GDAL is not installed.
- Metadata endpoint connected to dataset records.
- Fixture-driven tests.

## Constraints

- Do not fake metadata as real processing.
- Unsupported file types must produce controlled errors.
- Keep CRS/bounds/resolution fields explicit.

## Validation

- Vector metadata tests pass.
- Raster service imports or unavailable-state test passes.
- API contract remains stable.

## Acceptance

- Demo GeoJSON fixture returns deterministic metadata.
- Dataset metadata can be retrieved.
- Execution log updated.
