# Codex Pass 05 — Raster/Vector Metadata Core

## Goal

Make uploaded raster/vector datasets inspectable.

## Must implement

- raster metadata via Rasterio when available;
- vector metadata via GeoPandas/Fiona when available;
- CRS/bounds/feature count/bands/resolution where applicable;
- robust fallback errors when dependencies are unavailable;
- metadata endpoint;
- tests with small fixtures.

## Must preserve

- raw inputs immutable;
- metadata JSON persisted;
- errors structured.

## Output

Use `docs/M6_FINAL_HANDOFF_TEMPLATE.md`.
