MCR Final-2026 Engine Correctness Test Set — usage note
========================================================

This dataset consists of machine-generated game logs from the IJCAI-2026
Mahjong AI Competition Final Stage 2, played on the Botzone platform
(https://botzone.org.cn) between four autonomous bots. The logs record only
game protocol events (deals, draws, discards, claims, wins, scores) produced
by the competition judge and the bots' action strings.

- Redistributed for research and engineering use: engine/judge correctness
  testing, rules verification, game-AI and imitation-learning research.
- The bot policies (code, model weights) that produced the moves are NOT
  included and remain the property of their respective authors.
- Match records were harvested from the publicly viewable Botzone match
  archive. Player identifiers are the public competition user/bot names.
- No warranty of any kind. If you believe any content should not be
  redistributed, open a discussion on the dataset page.
