feat: Phase 2.4 レガシーアーカイブ整理完了（151MB削減）
## 🎉 完了項目 - ✅ plugin_box_legacy.rs削除（7.7KB、参照ゼロ確認済み） - ✅ REMOVEDコメント整理（encode.rs簡潔化） - ✅ venv削除（143MB節約、.gitignoreは既存） - ✅ llvm_legacyスタブ化（8KB、compile_error!による安全化） ## 🏆 成果 - **リポジトリサイズ改善**: 151MB削減 - **コード整理**: レガシーコード安全にアーカイブ - **プラグインファースト**: StrictPluginFirst継続動作 ## ✅ 検証完了 - cargo build --release --features llvm (警告のみ、エラーなし) - LLVMハーネス実行: print出力正常 - プラグイン動作: StringBox等正常動作 codex先生の戦略に従った安全な段階的削除を実行 Co-Authored-By: codex <noreply@anthropic.com>

# Legacy Rust/inkwell LLVM backend
|
||||
|
||||
This directory holds the historical LLVM backend implemented in Rust with inkwell.
|
||||
|
||||
- Status: DEPRECATED — kept for reference.
|
||||
- Current primary LLVM path is Python/llvmlite under `src/llvm_py/`.
|
||||
- Cargo feature to enable this backend: `llvm-inkwell-legacy`.
