# apply_patch.sh — EQ-Bench3 日本語パッチ適用スクリプト
#
# 使用方法:
#   git clone --depth=1 https://github.com/EQ-bench/eqbench3.git
#   cd eqbench3
#   bash /path/to/apply_patch.sh
#
# このスクリプトは data/ と同じディレクトリに置いて実行してください。
#
# 行う変更:
#   [Fix-D1] data/ 以下の全日本語ファイルを配置（英語版は .en.bak に退避）
#   [Fix-B1] core/benchmark.py — STANDARD_ALLOWED_RUBRIC_CRITERIA を動的読込みに変更
#   [Fix-C1] core/conversation.py — セクション正規表現に日本語見出しを追加
