: AIアドバイザーフィードバック - 各フォルダにREADME.md作成で導線改善 ## 🔧 ChatGPT5によるVMリファクタリング - vm_instructions.rs (1927行) をモジュール分割: - boxcall.rs : Box呼び出し処理 - call.rs : 関数呼び出し処理 - extern_call.rs : 外部関数処理 - function_new.rs : FunctionBox生成 - newbox.rs : Box生成処理 - plugin_invoke.rs : プラグイン呼び出し - VM実行をファイル分割で整理: - vm_state.rs : 状態管理 - vm_exec.rs : 実行エンジン - vm_control_flow.rs : 制御フロー - vm_gc.rs : GC処理 - plugin_loader_v2もモジュール化 ## ✨ 新機能実装 - FunctionBox呼び出しのVM/MIR統一進捗 - ラムダ式のFunctionBox変換テスト追加 - 関数値の直接呼び出し基盤整備 次ステップ: ANCPプロトタイプ実装開始（Week 1） 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude ---
