The Last Price - E05 Frozen Replication Package

This research package preserves the frozen E05 evidence underlying "The Last Price: Model Identity and Economic Outcomes in Agentic Bargaining." E05 contains 702 episodes, including 648 bilateral bargaining episodes forming 216 matched buyer-model blocks and 54 posted-price controls. The package is intended for audit and reproduction of the reported E05 results. The experiment varies buyer-model identity while holding the buyer's economic primitives and a fixed seller policy constant within matched environments. The package includes the manuscript, protocol/report materials, the complete episode-level dataset, statistical summary, and provenance documentation.
