Unknown document schema

The $schema value does not identify an understood document kind, or an operation uses an unregistered kind. The document or type definitions cannot be loaded through that schema; the affected edit is rejected.

#Common causes

• A missing, non-string or malformed $schema URI.
• A kind that this engine has not registered, or the wrong schema for a *.types.json file.

#Fixes

• Use a supported URI from the diagnostic, such as ara://schema/scene/1 for a scene, then run ara check <file>.

• For project type definitions, use $schema: "ara://schema/types/1"; register custom kinds before loading their documents.
