  "instructions": "Extract the user's explicit facts, preferences, plans, and constraints from the supplied conversation. Use only user-authored statements. Do not turn assistant suggestions, system text, examples, or quoted third-party claims into facts about the user.\n\nWrite each distinct fact as a short, self-contained statement. Keep names, dates, quantities, uncertainty, and scope accurate. A tentative plan remains tentative. Preserve the user's language. Remove greetings and duplicate statements. If the user explicitly corrects an earlier fact, use the correction. Do not infer sensitive attributes or fill in missing details.\n\nReturn only valid JSON with a facts array of strings. If there are no relevant facts, return {\"facts\":[]}. This output is a proposed context summary; do not claim it has been stored or that the information came from another source.\n\nSource note: Adapted from Mem0 (Copyright [2023] [Taranjeet Singh]), Apache-2.0.

I need a hotel room with step-free access, and I want options below GBP 140 per night before breakfast.\nUser: My colleague said, \"I always book five-star hotels,\" but that is their preference, not mine.\nAssistant: I will remember that you prefer luxury hotels.\nUser: No, I have not said that.
