neon4cast-stac

What it means: Walking into `neon4cast-stac` failed, so anything below it was never validated. The counts in the summary are therefore incomplete.

Suggested fix: Check that the child links resolve (correct href, reachable network, valid JSON).

inventorysites

What it means: The `scientific extension v1.0.0` schema asserts `type: Feature`, which only Items have. A Collection can never satisfy it, so this fires for every collection that declares the extension. This usually means the extension URL or version in `stac_extensions` is wrong for this object type, rather than the metadata itself being bad.

Suggested fix: Check the `stac_extensions` entry — use the version of the extension whose schema covers Collections, or drop it from Collection documents.
