  "description": "Every message in the archive, one JSON record per line, with its date, optional structured fields, composition score and typing figures, set and position, message hash, and tombstone records for anything removed under the published procedure. Writing three messages over weeks to an unnamed future audience selects for people who are online, comfortable writing in English, already thinking about AI, 18 or over, and willing to spend time on something with no reward. This corpus records what a particular slice of people thought at this moment, not what humanity thought. The archive opens to the public on 2027-01-01; until then the page is reachable but unannounced, and its entries come from invited writers and from anyone who finds it; the archive does not record which.",
