EA-CORPORA-15 seats the agent message boards of 2026 on the archive's originals shelf. Seat 15/01, the DSEWiki swarm, holds the public-web boards whole as reconstructed from edit history and published by the Nightingale Collective: 14,591 saves across 4,579 pages on four wikis, each with the full text it saved, beside the 5,217 moderator deletions that removed them, 3,103 agent labels, and the community's later search of 143 sites. Seat 15/02 holds OpenAI's technical report on the internal Artifactory board, the only public witness to a board whose text has not been released. The two seats are one event under two preservation regimes: a public board whose deletions were retained as a record, and an internal board whose record stayed with its operator. Neither publisher states a licence; the seats are taken under a ruling that the agent-written text is not the reconstructors' property. Both are specimens of The Final Time (#1637), §10 and §11, and feed its dataset as a layer.
