+# ComfyUI-Workflow-Studio 開発ガイドライン
+
+## プロジェクト概要
+ComfyUI用ワークフロー管理プラグイン。aiohttp (ComfyUI PromptServer) 上でSPAを提供する。
+
+## アーキテクチャ
+- エントリポイント: `__init__.py` → `py/wfm.py` (WorkflowStudio.add_routes)
+- バックエンド: `py/routes/` (aiohttp ルート), `py/services/` (ビジネスロジック)
+- フロントエンド: `web/comfyui/` (ComfyUI拡張), `static/` (SPA), `templates/` (Jinja2)
+- データ: `data/` (settings.json, metadata.json, node_metadata.json)
+- i18n: 英語 / 日本語 / 中国語
+
+---
+
+## ComfyUI カスタムノード開発ルール
+
+### NODE_CLASS_MAPPINGS キーは永久に変更不可
+`NODE_CLASS_MAPPINGS` のキー文字列は、保存済みワークフローとノードを紐付ける公開識別子。
+一度公開したキーを変更すると、ユーザーの既存ワークフローが壊れる。
+将来ノードを追加する場合は、キー名を慎重に決定すること。
+- 名前空間衝突を防ぐため、パック名をプレフィックスに付ける (例: `"WFS_MyNode"`)
+- リネーム時は旧キーをエイリアスとして残す:
+  ```python
+  NODE_CLASS_MAPPINGS = {
+      "WFS_NewName": MyNodeClass,   # 新名
+      "WFS_OldName": MyNodeClass,   # エイリアス（後方互換）
+  }
+  ```
+
+### ワークフローJSON: ウィジェット値は位置インデックスで格納される
+ワークフローJSONはウィジェットの値を「名前」ではなく「位置インデックス」で保存する。
+入力の追加・並べ替えは、保存済みワークフローの値を別パラメータにずらす破壊的変更になる。
+ワークフロー解析・編集コード (`workflow_analyzer.py`, `workflow_service.py`) を変更する際は、
+このインデックスマッピングを必ず考慮すること。
+
+**INPUT_TYPES変更時のチェックリスト:**
+- ウィジェット追加: 末尾に追加が最も安全。中間挿入は全保存済みJSONの更新が必要
+- ウィジェット削除: 後続のインデックスが全てずれる。全保存済みJSONの`widgets_values`を修正
+- 並べ替え: `widgets_values`の順序も合わせて更新
+- `INPUT_TYPES`を変更するコミットは、影響を受けるワークフローJSONも同時にコミットする
+
+### ワークフローJSON整合性ルール
+- `last_node_id` は最大ノードID以上であること（低いと重複IDが発生し無言で壊れる）
+- `last_link_id` は最大リンクID以上であること
+- リンクは3箇所で整合する必要がある: `links[]`配列、ソースノードの`outputs[slot].links`、ターゲットノードの`inputs[slot].link`
+- いずれかが不一致だと接続が無言で消える
+
+### IS_CHANGED によるキャッシュ制御
+ComfyUIはキャッシュ付きデータフローグラフ実行エンジン。入力が変わらないと判断したノードはスキップされる。
+- 毎回実行が必要なノード: `IS_CHANGED` で `float("NaN")` を返す
+- 本番用: 入力に基づく決定論的なハッシュを返す
+- 注意: `IS_CHANGED` はスロット接続された入力に `None` を受け取ることがある。`None`チェックを必ず入れる
+
+### VALIDATE_INPUTS の落とし穴
+スロット接続された入力は検証時に `None` として渡される（実行時には実値が来る）。
+```python
+@classmethod
+def VALIDATE_INPUTS(cls, text=None, **kwargs):
+    if text is None:
+        return True  # スロット接続 — 実行時に実値が来る
+    if isinstance(text, str) and text.strip() == "":
+        return "Text input cannot be empty"
+    return True
+```
+
+### ノードの安全な分離読み込み
+1つの壊れた依存が全ノードを道連れにしないよう、個別にtry/exceptで読み込む:
+```python
+NODE_CLASS_MAPPINGS = {}
+for name, (mod_path, cls_name) in _NODE_MODULES.items():
+    try:
+        mod = importlib.import_module(mod_path, package=__name__)
+        NODE_CLASS_MAPPINGS[name] = getattr(mod, cls_name)
+    except Exception as e:
+        print(f"[WARNING] Failed to load '{name}': {e}")
+```
+
+### Hidden Inputs (UNIQUE_ID, PROMPT, EXTRA_PNGINFO)
+```python
+"hidden": {
+    "unique_id": "UNIQUE_ID",      # キャッシュの名前空間キーに使用
+    "prompt": "PROMPT",
+    "extra_pnginfo": "EXTRA_PNGINFO",  # PNG出力にメタデータ埋め込み
+}
+```
+`UNIQUE_ID`を使わずモジュールレベルキャッシュを共有すると、同一ノードの複数インスタンスが干渉する。
+
+### Lazy Inputs & 条件付き実行
+不要な上流実行を防ぐ:
+```python
+# INPUT_TYPESで宣言
+"optional": {"heavy_data": ("IMAGE", {"lazy": True})}
+
+# 必要な入力だけリクエスト
+def check_lazy_status(self, **kwargs):
+    needed = []
+    if self.needs_heavy_data:
+        needed.append("heavy_data")
+    return needed  # 空リスト = 上流実行をスキップ
+```
+
+---
+
+## 開発時の注意事項
+
+### Python変更後は必ずComfyUIを再起動
+ComfyUIは起動時に `custom_nodes/` を一度だけインポートする。
+Pythonファイルの変更はComfyUIプロセスの完全再起動まで反映されない。
+
+### __pycache__ のクリア
+ディレクトリ間のコピーやブランチ切り替え後、古いバイトコードが残ることがある。
+動作がおかしい場合は `__pycache__/` を削除してから再起動する。
+
+### 依存パッケージのインストール先
+Windows Portable版のComfyUIは `python_embeded/` 内の組み込みPythonを使用する。
+システムのPythonにインストールしても認識されない。
+```
+python_embeded/python.exe -m pip install package_name
+```
+torch関連パッケージはCUDA index URLを指定:
+```
+python_embeded/python.exe -m pip install torchaudio --index-url https://download.pytorch.org/whl/cu130
+```
+インストール後は必ず `torch.cuda.is_available()` で確認する。
+
+### デプロイ
+ソースリポジトリと `custom_nodes/` のランタイムディレクトリは分離する。
+`custom_nodes/` 内で直接編集せず、同期スクリプトでパッケージ全体をデプロイする。
+部分的な同期は原因不明のエラーを引き起こす。
+デプロイ後はハッシュ比較でファイル同一性を検証する。
+
+### prestartup_script.py
+環境変数の設定は `__init__.py` では遅い。`prestartup_script.py` はノードインポート前に実行される唯一の場所:
+```python
+# custom_nodes/ComfyUI-Workflow-Studio/prestartup_script.py
+import os
+os.environ["HF_HOME"] = "D:\\hf_cache"
+```
+
+### 依存パッケージの競合防止
+- 依存はゆるくピン留め: `transformers>=4.40,<6.0` (厳密な `==` は避ける)
+- torchは `requirements.txt` にピン留めしない（ComfyUI本体が管理）
+- バージョン依存のインポートは `try/except` でフォールバック
+
+### テスト戦略 (ComfyUI不要のテスト)
+1. `ast.parse()` で構文チェック (0.1秒)
+2. ビジネスロジックを `execute()` から分離し pytest でテスト (1-2秒)
+3. ComfyUI統合テストは最終確認のみ (30-60秒)
+
+### ファイルパスの扱い
+出力・一時ファイルは `folder_paths.get_output_directory()` / `folder_paths.get_temp_directory()` を使用。
+相対パスはComfyUIの起動方法によって解決先が変わる。
+
+### Windows固有の注意
+- PowerShellのデフォルトエンコーディングはUTF-8を壊す。ファイル書き込みはPython経由で行う
+- Windows MAX_PATH (260文字) 制限: 浅いパス (`C:\ComfyUI`) にインストールするか、LongPathsEnabled レジストリを有効化
+- HuggingFaceのシンボリックリンクは開発者モードなしだと無言でファイルが複製される (`HF_HOME`を短いパスに設定)
+
+### バウンドキャッシュ
+モジュールレベルのキャッシュは `OrderedDict` + 最大サイズ制限で実装する。
+無制限キャッシュは長時間セッションでメモリを食い潰す。
+
+---
+
+## サイレント障害の診断
+
+| 症状 | 原因 | 対処 |
+|------|------|------|
+| 編集後も動作が変わらない | 古いコード | ComfyUI再起動 + `__pycache__/` 削除 |
+| 変更したのにノードが実行されない | キャッシュ | `IS_CHANGED` で `float("NaN")` を返す |
+| ワークフロー読込で値がおかしい | UIマッピングずれ | ウィジェット位置が保存JSONと一致するか確認 |
+| ノードが赤い "missing" 表示 | タイプ名不一致 | `NODE_CLASS_MAPPINGS` のキーと大文字小文字を確認 |
+| 接続線が消える | リンクID不整合 | links[], outputs[].links, inputs[].link の3箇所を検証 |
+| 重複ノード動作 | `last_node_id` が低すぎる | 最大ノードID + 1 に設定 |
+| CUDAが使えなくなった | CPU版wheelのインストール | `torch.cuda.is_available()` 確認、CUDA index URLで再インストール |
+| ヘッドレスモードで失敗 | UI前提のコード | `{"ui": {...}, "result": (...)}` で分離 |
+
+---
+
+## コミット前チェックリスト
+1. 全ファイルを `custom_nodes/` に同期（部分同期しない）
+2. 両方の `__pycache__/` をクリア
+3. 全 .py ファイルのハッシュ比較で同一性を確認
+4. `ast.parse()` で全 .py ファイルの構文チェック
+5. `INPUT_TYPES` 変更時は `widgets_values` も同時更新
+6. 削除した依存への参照が残っていないか grep で確認
+7. ComfyUI完全再起動 → ワークフロー読み込み → エンドツーエンド実行確認

+### 概要
+- テーマのカラーカスタマイズ、背景パターン、フォント選択機能を追加
+- 設定タブの各セクションをアコーディオン式折りたたみに変更
+- ヘルプタブのSettings Tab説明を更新
+
+### 変更内容
+
+#### `static/js/settings-tab.js` — テーマカスタマイズ機能追加
+- **カラーオーバーライド:** 6つのCSS変数（背景、サブ背景、サーフェス、テキスト、プライマリ、アクセント）をカラーピッカーでリアルタイム調整、localStorageに保存
+- **背景パターン:** 7種類（なし、横/縦/斜めストライプ、ポルカドット、チェック、SVGファイル）を選択可能
+  - パターンオプション: 色、不透明度、サイズ、間隔（gap）スライダー
+  - SVGタイリング: FileReader APIでクライアント側読込、色の置換（fill/stroke属性＋`<style>`要素注入）、`::after`疑似要素でopacity制御、gap対応はviewBox拡張ラッパーSVG方式
+- **フォント選択:** 16種のGoogle Fonts（日本語デザインフォント含む）を動的ロード、クリックで即時プレビュー
+  - ゴシック系: Noto Sans JP, Zen丸ゴシック, M PLUS Rounded, 小杉丸ゴシック, さわらびゴシック, BIZ UDPゴシック
+  - デザイン系: ドットゴシック16, はちまるポップ, デラゴシック, レゲエ One, ロックンロール, ステッキ, トレイン One
+  - 等幅: Space Mono, Fira Code
+- **保存ロジック修正:** `saveLocalSettings()`のスプレッドマージでは`delete`したキーが消えない問題を修正、リセット時は`localStorage.setItem()`で直接上書き
+- **SVGリカラー強化:** `<style>`ブロックをSVGに注入し、fill属性がない要素にも色を適用
+
+#### `static/css/main.css` — UIスタイル追加
+- **設定アコーディオン:** `<details>`/`<summary>`要素用のスタイル（`.wfm-settings-section`, `.wfm-settings-summary`）— 三角矢印回転アニメーション付き

+
+#### `static/js/app.js` — i18nマッピング追加
+- `helpSettings7`, `helpSettings8` のHTML id→i18nキーマッピングを追加
+
+#### `templates/index.html` — ヘルプタブ更新
+- Settings Tabセクション: テーマカスタマイズ機能の説明を追加（項目2）、Eagle連携を項目7に、アコーディオン折りたたみを項目8に追加
+
+### 技術的な判断
+- **SVGカラー変更:** 属性置換だけでは不十分なSVG（CSSクラスやデフォルト黒を使用）に対応するため、`<style>`ブロック注入方式を採用
+- **SVG間隔（gap）:** viewBoxを拡張するラッパーSVGでタイル間に余白を作成
+- **フォント読込:** Google Fonts CDNから動的にlinkタグを挿入、一度読み込んだフォントはSetで管理し重複読込を防止
+- **アコーディオン:** `<details>`/`<summary>`ネイティブHTML要素を使用、JSなしで開閉動作
+
+## 2026-03-26: トップバーボタンアイコン修正・Appモードバッジ調査
+
+### 概要
+- トップバーの3つのボタン（Workflow Studio / Snapshot / Library）のアイコンが表示されない問題を修正
+- ComfyUI Appモード（linearMode）のワークフローJSON構造を調査、バッジ表示対応は保留
+
+### 変更内容
+
+#### `web/comfyui/top_menu_extension.js` — アイコン置換ロジック修正
+- **問題:** `setup()` 内の `replaceButtonIcon()` が `requestAnimationFrame` でボタンを見つけてSVGを注入するが、ComfyUIのVueフレームワークが再レンダリングして元の `<i class="icon-[mdi--...]">` に戻してしまう。リトライ条件が `wfmButtons.length === 0`（ボタン未検出時のみ）のため、一度見つかった後は再注入されなかった
+- **修正:** `MutationObserver` でボタンの親コンテナ（`.actionbar-container`）を監視し、DOMが変更されるたびにSVGアイコンを再注入するように変更
+- `applyButtonIcon()`: ボタンに既にSVGがあればスキップ（無限ループ防止）、なければSVG注入
+- `waitAndObserve()`: ボタンがDOMに現れるまで `requestAnimationFrame` で待機し、見つかったらアイコン置換＋`MutationObserver`監視開始
+
+### Appモードバッジ表示について（保留）
+- ComfyUI Appモード（BETA機能）のワークフローJSON構造を調査
+- `extra.linearMode: true` と `extra.linearData` （inputs/outputs配列）でappモード情報が格納される
+- appモード削除後も `linearData`/`linearMode` キーは残り中身が空配列になるだけ、拡張子 `.app.json` も維持される
+- **結論:** Appモード自体がBETA機能のため、バッジ表示対応は現状維持とする
+
+## 2026-03-25: v0.2.0 プロンプトプリセット機能・Workflow Studio Library
+
+### 概要
+- プロンプトプリセット機能を追加：サイドパネルからドラッグ＆ドロップでWFS_PromptTextカスタムノードを作成

ketle-manandClaude Opus 4.6	4a890d1312	Fix SVG pattern disappearing when gap > 0 for non-standard viewBox SVGs with non-default viewBox (e.g. "0 -960 960 960") lost their content when wrapped in a nested SVG for gap spacing, because the inner SVG did not inherit the original viewBox. Now extracted and preserved. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-03-27 09:49:15 +09:00
