Phase 25.1 完了成果: - ✅ LoopForm v2 テスト・ドキュメント・コメント完備 - 4ケース(A/B/C/D)完全テストカバレッジ - 最小再現ケース作成(SSAバグ調査用) - SSOT文書作成(loopform_ssot.md) - 全ソースに [LoopForm] コメントタグ追加 - ✅ Stage-1 CLI デバッグ環境構築 - stage1_cli.hako 実装 - stage1_bridge.rs ブリッジ実装 - デバッグツール作成(stage1_debug.sh/stage1_minimal.sh) - アーキテクチャ改善提案文書 - ✅ 環境変数削減計画策定 - 25変数の完全調査・分類 - 6段階削減ロードマップ(25→5、80%削減) - 即時削除可能変数特定(NYASH_CONFIG/NYASH_DEBUG) Phase 26-D からの累積変更: - PHI実装改善(ExitPhiBuilder/HeaderPhiBuilder等) - MIRビルダーリファクタリング - 型伝播・最適化パス改善 - その他約300ファイルの累積変更 🎯 技術的成果: - SSAバグ根本原因特定(条件分岐内loop変数変更) - Region+next_iパターン適用完了(UsingCollectorBox等) - LoopFormパターン文書化・テスト化完了 - セルフホスティング基盤強化 Co-Authored-By: Claude <noreply@anthropic.com> Co-Authored-By: ChatGPT <noreply@openai.com> Co-Authored-By: Task Assistant <task@anthropic.com>
