PyVM迂回路の混乱事件 - Break/Continue無限ループ事件 - EXE-first戦略の再発見 - 論文I（開発秘話）: Day 38の重要決定追加 ### 🧪 テストケース追加 - apps/tests/: ループ制御とPHIのテストケース - nested_loop_inner_break_isolated.nyash - nested_loop_inner_continue_isolated.nyash - loop_phi_one_sided.nyash - shortcircuit関連テスト ## 技術的詳細 - Break/ContinueをMIRレベルで適切に処理 - 無限ループ問題（CPU 99.9%暴走）の根本解決 - 将来の例外処理機能への準備 🤖 Generated with [Claude
