Game-theoretic profiling of behavioral signatures in 25 frontier language models: Raw decision corpus

Raw per-trial JSON corpus accompanying Affonso, F.M. (2026), "Game-theoretic profiling reveals provider-specific behavioral signatures in frontier language models." Contains 51,906 individual JSON files (one per trial), each with the full prompt sent to the model, the verbatim text response, parsed choices, payoffs, reasoning traces, and complete trial metadata (model snapshot identifiers, opponent, condition, trial number, UTC timestamp). Compressed total: 191 MB; uncompressed: 4.1 GB. This is the immutable source-of-truth dataset; the aggregated CSV summary and analysis pipeline are deposited separately at 10.5281/zenodo.19837539.
