# To interprete differences is not obvious (for me), SEE https://www.npmjs.com/package/json-schema-diff
#
# TIPS to debug
#  1. create the dst json-schema manually through the pydantic type (see Makefile recipies in models-library)
#  2. resolve both src/dst using json-resolver (see https://github.com/davidkelley/json-dereference-cli
#      callable from ./scripts/json-schema-dereference.bash schema.json schema-deref.json)
#  3. compare both files in vscode
