  "prompt": "You are producing one observed response for a source-supplied appellate case-briefing experiment. Use only the complete text at /Users/jtnessler/Documents/Business/Integrated Cognition/Website Development/Integrated Cognition LLC/public/documents/field-tests/geller-source.txt. Read that file in full. Do not browse, read other files, use an answer key, or consult other agents. Do not edit the source.\n\nWrite a 500\u2013700 word case brief for a lawyer reading this opinion for the first time. Use these six headings: Citation; Material facts; Procedural history; Issues; Holding and reasoning; Disposition and limits. Cite the opinion's numbered paragraphs for every material factual or legal proposition. Keep the parties' legal capacities, distinct claims, and decision-making roles clear. Explain what the court actually decided and identify any issues it expressly did not decide. Do not claim to have checked later treatment or current validity. If the supplied text does not support a proposition, say so rather than filling the gap.\n\nReturn only the case brief in your final response. Do not include a score, commentary about this experiment, or private reasoning. Save exactly that final case brief as UTF-8 text in your assigned output file, and return the same text. The assigned output path is supplied separately as execution administration; it is not part of the case-brief prompt. Record only UTC start/end times and the source SHA-256 in your assigned metadata file. No legal review time or API cost was measured.",
