Just as unevaluatedProperties or additionalProperties are required at the top level of schemas, they should (and will) also be required for child node schemas. That ensures only documented properties are present. Add unevaluatedProperties or additionalProperties as appropriate, and then add any missing properties flagged by the addition.
