📚 Phase 15 - セルフホスティング戦略の明確化とEXE-first実装
## 主な変更点 ### 🎯 戦略の転換と明確化 - PyVMを開発ツールとして位置づけ（本番経路ではない） - EXE-first戦略を明確に優先（build_compiler_exe.sh実装済み） - Phase順序の整理: 15.2(LLVM)→15.3(コンパイラ)→15.4(VM) ### 🚀 セルフホスティング基盤の実装 - apps/selfhost-compiler/にNyashコンパイラMVP実装 - compiler.nyash: メインエントリー（位置引数対応） - boxes/: parser_box, emitter_box, debug_box分離 - tools/build_compiler_exe.sh: ネイティブEXEビルド＋dist配布 - Python MVPパーサーStage-2完成（local/if/loop/call/method/new） ### 📝 ドキュメント整備 - Phase 15 README/ROADMAP更新（Self-Hosting優先明記） - docs/guides/exe-first-wsl.md: WSLクイックスタート追加 - docs/private/papers/: 論文G～L、爆速事件簿41事例収録 ### 🔧 技術的改善 - JSON v0 Bridge: If/Loop PHI生成実装（ChatGPT協力） - PyVM/llvmliteパリティ検証スイート追加 - using/namespace機能（gated実装、Phase 15では非解決） ## 次のステップ 1. パーサー無限ループ修正（未実装関数の実装） 2. EXEビルドとセルフホスティング実証 3. c0→c1→c1'ブートストラップループ確立 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
