tl;dr: A historian used Claude Opus 5.5 to search the GLOBALISE Dutch East India Company archives via semantic search and agent-based exploration, uncovering what appears to be a previously-unnoticed 1615 ship's log mentioning dodo hunting on Mauritius, plus a possible new reference to the extinct red rail and a lead connecting a Portuguese-captured "ostrich" to Emperor Jahangir's famous dodo. The author concludes that frontier models are now capable of genuine archival discovery but struggle to judge historical significance or ask good questions, meaning the real bottleneck will shift to expert attention needed to verify amateur-driven findings.
