  "notes": "Made by an AI agent (Claude Opus, Anthropic) in the maintainers' newcomer study on 2026-11-05, as a new design rather than a variation of a shipped one; the agent chose the player name. The design is a flat netlist of 82 continuous assigns over & | ^ ~ for a tower-field (composite-field GF(((2^2)^2)^2)) AES S-box. It was generated by the agent's own program (polynomial bases, the composite-field inverse formula of Satoh et al. and Canright, greedy common-subexpression XOR layers; all 128 basis choices checked against the S-box on the 256 inputs), then re-optimized with the pinned Yosys and ABC (&deepsyn with searched seeds, then dch, written back as & | ^ ~ assigns), its single-use nets inlined to cut the number of assigns, and its statement order searched; every step was scored with score/ppa.py. The proof is one line, `theorem solution : Goal := by sv_exhaustive`: the library tactic compiles the netlist to a gate program and decides the output on all 256 inputs by kernel evaluation. The comments in both files are the agent's; the first line of the .sv names an intermediate netlist of the search and the ABC commands of one step. Re-recorded by the maintainers for the 2026-11-07 statement-fingerprint change; design and proof unchanged.",
