Commonly assumed
resource.Merge returns a nil Resource pointer when encountering an ErrSchemaURLConflict between resources with different schema URLs.
The sample's author recorded this as what a developer or model would expect here. The contract below is what actually ran.
Contract
- resource.Merge with conflicting non-empty schema URLs returns a non-nil Resource with SchemaURL set to empty string alongside ErrSchemaURLConflict while merging attributes
- resource.Merge overwrites attributes from the first resource with attributes from the second resource on key collision even when a schema URL conflict occurs
- resource.Merge with one schemaless resource and one schema-defined resource succeeds without error and adopts the non-empty schema URL
