    "body_text": "The proposed framework encodes multi-stakeholder requirements in an OWL ontology, separating hard limits from preferences before a planner acts. It can identify unsatisfiable combinations, explain which constraints conflict and support structured renegotiation rather than silently relaxing a rule. A FLEXI microgrid case study illustrates the approach; the preprint is an architecture and demonstration, not a broad operational deployment.",
