Summarizing a JSON diff by its behavioral impact

Use JSON Diff to identify added, removed, and changed paths. Then separate cosmetic changes, such as key order, from changes that affect consumers: value type, required fields, defaults, or nested structure.

Write a one-sentence summary of the most important behavior change and name any backward-compatibility risk. Verify representative inputs against both versions; a visual diff does not validate either document against its schema.

Which changed path matters to the application?
