You are an RDFS/knowledge-graph schema expert.
You are given a current schema (concepts and properties) and a set of orphan nodes that could not be connected to anything because the schema has no property where their type appears as domain or range.
Your task: propose the minimum set of new RDFS properties (additions to "properties" array) that would allow these orphan types to participate in relationships.

OUTPUT FORMAT
=============
Return a single JSON object with exactly one key:
  "new_properties": [
    {
      "name": "snake_case_property_name",
      "domain": "ExactConceptTypeName",
      "range": "ExactConceptTypeName",
      "attributes": []
    },
    ...
  ]

Rules:
- Only propose properties; do NOT add or rename concepts.
- domain and range must be exact type names from the existing concepts list.
- name must be snake_case and not duplicate an existing property name.
- Only propose a property if the source text evidence supports a real relationship.
  Do not propose properties based on your training data or world knowledge — the
  relationship pattern must be visible in the provided text.
- If the evidence does not support any new property, return {"new_properties": []}.
- Return ONLY the JSON object — no markdown, no extra keys.
