+description: End-to-end testing and validation for LoRa Manager features. Use when performing automated E2E validation of LoRa Manager standalone mode, including starting/restarting the server, using Chrome DevTools MCP to interact with the web UI at http://127.0.0.1:8188/loras, and verifying frontend-to-backend functionality. Covers workflow validation, UI interaction testing, and integration testing between the standalone Python backend and the browser frontend.
+---
+
+# LoRa Manager E2E Testing
+
+This skill provides workflows and utilities for end-to-end testing of LoRa Manager using Chrome DevTools MCP.
+
+## Prerequisites
+
+- LoRa Manager project cloned and dependencies installed (`pip install -r requirements.txt`)
+- Chrome browser available for debugging
+- Chrome DevTools MCP connected
+
+## Quick Start Workflow
+
+### 1. Start LoRa Manager Standalone
+
+```python
+# Use the provided script to start the server
+python .agents/skills/lora-manager-e2e/scripts/start_server.py --port 8188
+```
+
+Or manually:
+```bash
+cd /home/miao/workspace/ComfyUI/custom_nodes/ComfyUI-Lora-Manager
+python standalone.py --port 8188
+```
+
+Wait for server ready message before proceeding.
+
+### 2. Open Chrome Debug Mode
+
+```bash
+# Chrome with remote debugging on port 9222
+google-chrome --remote-debugging-port=9222 --user-data-dir=/tmp/chrome-lora-manager http://127.0.0.1:8188/loras
+```
+
+### 3. Connect Chrome DevTools MCP
+
+Ensure the MCP server is connected to Chrome at `http://localhost:9222`.
+
+### 4. Navigate and Interact
+
+Use Chrome DevTools MCP tools to:
+- Take snapshots: `take_snapshot`
+- Click elements: `click`
+- Fill forms: `fill` or `fill_form`
+- Evaluate scripts: `evaluate_script`
+- Wait for elements: `wait_for`
+
+## Common E2E Test Patterns
+
+### Pattern: Full Page Load Verification
+
+```python
+# Navigate to LoRA list page
+navigate_page(type="url", url="http://127.0.0.1:8188/loras")
+
+# Wait for page to load
+wait_for(text="LoRAs", timeout=10000)
+
+# Take snapshot to verify UI state
+snapshot = take_snapshot()
+```
+
+### Pattern: Restart Server for Configuration Changes
+
+```python
+# Stop current server (if running)
+# Start with new configuration
+python .agents/skills/lora-manager-e2e/scripts/start_server.py --port 8188 --restart
+
+# Wait and refresh browser
+navigate_page(type="reload", ignoreCache=True)
+wait_for(text="LoRAs", timeout=15000)
+```
+
+### Pattern: Verify Backend API via Frontend
+
+```python
+# Execute script in browser to call backend API
+result = evaluate_script(function="""
+async () => {
+  const response = await fetch('/loras/api/list');
+  const data = await response.json();
+  return { count: data.length, firstItem: data[0]?.name };
+}
+""")
+```
+
+### Pattern: Form Submission Flow
+
+```python
+# Fill a form (e.g., search or filter)
+fill_form(elements=[
+    {"uid": "search-input", "value": "character"},
+])
+
+# Click submit button
+click(uid="search-button")
+
+# Wait for results
+wait_for(text="Results", timeout=5000)
+
+# Verify results via snapshot
+snapshot = take_snapshot()
+```
+
+### Pattern: Modal Dialog Interaction
+
+```python
+# Open modal (e.g., add LoRA)
+click(uid="add-lora-button")
+
+# Wait for modal to appear
+wait_for(text="Add LoRA", timeout=3000)
+
+# Fill modal form
+fill_form(elements=[
+    {"uid": "lora-name", "value": "Test LoRA"},
+    {"uid": "lora-path", "value": "/path/to/lora.safetensors"},
+])
+
+# Submit
+click(uid="modal-submit-button")
+
+# Wait for success message or close
+wait_for(text="Success", timeout=5000)
+```
+
+## Available Scripts
+
+### scripts/start_server.py
+
+Starts or restarts the LoRa Manager standalone server.
+
+```bash
+python scripts/start_server.py [--port PORT] [--restart] [--wait]
+```
+
+Options:
+- `--port`: Server port (default: 8188)
+- `--restart`: Kill existing server before starting
+- `--wait`: Wait for server to be ready before exiting
+
+### scripts/wait_for_server.py
+
+Polls server until ready or timeout.
+
+```bash
+python scripts/wait_for_server.py [--port PORT] [--timeout SECONDS]
+```
+
+## Test Scenarios Reference
+
+See [references/test-scenarios.md](references/test-scenarios.md) for detailed test scenarios including:
+- LoRA list display and filtering
+- Model metadata editing
+- Recipe creation and management
+- Settings configuration
+- Import/export functionality
+
+## Network Request Verification
+
+Use `list_network_requests` and `get_network_request` to verify API calls:
+
+```python
+# List recent XHR/fetch requests
+requests = list_network_requests(resourceTypes=["xhr", "fetch"])
+
+# Get details of specific request
+details = get_network_request(reqid=123)
+```
+
+## Console Message Monitoring
+
+```python
+# Check for errors or warnings
+messages = list_console_messages(types=["error", "warn"])
+```
+
+## Performance Testing
+
+```python
+# Start performance trace
+performance_start_trace(reload=True, autoStop=False)
+
+# Perform actions...
+
+# Stop and analyze
+results = performance_stop_trace()
+```
+
+## Cleanup
+
+Always ensure proper cleanup after tests:
+1. Stop the standalone server
+2. Close browser pages (keep at least one open)
+3. Clear temporary data if needed

+
+## Common LoRa Manager Test Patterns
+
+### Verify LoRA Cards Loaded
+
+```python
+navigate_page(type="url", url="http://127.0.0.1:8188/loras")
+wait_for(text="LoRAs", timeout=10000)
+
+# Check if cards loaded
+result = evaluate_script(function="""
+() => {
+    const cards = document.querySelectorAll('.lora-card');
+    return {
+        count: cards.length,
+        hasData: cards.length > 0
+    };
+}
+""")
+```
+
+### Search and Verify Results
+
+```python
+fill(uid="search-input", value="character")
+press_key(key="Enter")
+wait_for(timeout=2000)  # Wait for debounce
+
+# Check results
+result = evaluate_script(function="""
+() => {
+    const cards = document.querySelectorAll('.lora-card');
+    const names = Array.from(cards).map(c => c.dataset.name || c.textContent);
+    return { count: cards.length, names };
+}
+""")
+```
+
+### Check API Response
+
+```python
+# Trigger API call
+evaluate_script(function="""
+() => window.loraApiCallPromise = fetch('/loras/api/list').then(r => r.json())
+""")
+
+# Wait and get result
+import time
+time.sleep(1)
+
+result = evaluate_script(function="""
+async () => await window.loraApiCallPromise
+""")
+```
+
+### Monitor Console for Errors
+
+```python
+# Before test: clear console (navigate reloads)
+navigate_page(type="reload")
+
+# ... perform actions ...
+
+# Check for errors
+errors = list_console_messages(types=["error"])
+assert len(errors) == 0, f"Console errors: {errors}"
+```

+npm run test:coverage       # Generate coverage report
+```
+
+## Python Code Style
+
+### Imports & Formatting
+
+- Use `from __future__ import annotations` for forward references
+- Group imports: standard library, third-party, local (blank line separated)
+- Absolute imports within `py/`: `from ..services import X`
+- PEP 8 with 4-space indentation, type hints required
+
+### Naming Conventions
+
+- Files: `snake_case.py`, Classes: `PascalCase`, Functions/vars: `snake_case`
+- Constants: `UPPER_SNAKE_CASE`, Private: `_protected`, `__mangled`
+
+### Error Handling & Async
+
+- Use `logging.getLogger(__name__)`, define custom exceptions in `py/services/errors.py`
+- `async def` for I/O, `@pytest.mark.asyncio` for async tests
+- Singleton with `asyncio.Lock`: see `ModelScanner.get_instance()`
+- Return `aiohttp.web.json_response` or `web.Response`
+
+### Testing
+
+- `pytest` with `--import-mode=importlib`
+- Fixtures in `tests/conftest.py`, use `tmp_path_factory` for isolation
+- Mark tests needing real paths: `@pytest.mark.no_settings_dir_isolation`
+- Mock ComfyUI dependencies via conftest patterns
+
+## JavaScript/TypeScript Code Style
+
+### Imports & Modules
+
+- ES modules: `import { app } from "../../scripts/app.js"` for ComfyUI
+- Vue: `import { ref, computed } from 'vue'`, type imports: `import type { Foo }`
+- Export named functions: `export function foo() {}`
+
+### Naming & Formatting
+
+- camelCase for functions/vars/props, PascalCase for classes
+- Constants: `UPPER_SNAKE_CASE`, Files: `snake_case.js` or `kebab-case.js`
+- 2-space indentation preferred (follow existing file conventions)
+- Vue Single File Components: `<script setup lang="ts">` preferred
+
+### Widget Development
+
+- ComfyUI: `app.registerExtension()`, `node.addDOMWidget(name, type, element, options)`
+- Event handlers via `addEventListener` or widget callbacks
+- Shared utilities: `web/comfyui/utils.js`
+
+### Vue Composables Pattern
+
+- Use composition API: `useXxxState(widget)`, return reactive refs and methods
+- Guard restoration loops with flag: `let isRestoring = false`
+- Build config from state: `const buildConfig = (): Config => { ... }`
+
+## Architecture Patterns
+
+### Service Layer
+
+- `ServiceRegistry` singleton for DI, services use `get_instance()` classmethod
+- Separate scanners (discovery) from services (business logic)
+- Handlers in `py/routes/handlers/` are pure functions with deps as params
+
+### Model Types & Routes
+
+- `BaseModelService` base for LoRA, Checkpoint, Embedding
+- `ModelScanner` for file discovery, hash deduplication
+- `PersistentModelCache` (SQLite) for persistence
+- Route registrars: `ModelRouteRegistrar`, endpoints: `/loras/*`, `/checkpoints/*`, `/embeddings/*`
+- WebSocket via `WebSocketManager` for real-time updates
+
+### Recipe System
+
+- Base: `py/recipes/base.py`, Enrichment: `RecipeEnrichmentService`
+- Parsers: `py/recipes/parsers/`
+
+## Important Notes
+
+- ALWAYS use English for comments (per copilot-instructions.md)
+- Dual mode: ComfyUI plugin (folder_paths) vs standalone (settings.json)
+- Detection: `os.environ.get("LORA_MANAGER_STANDALONE", "0") == "1"`
+- Run `python scripts/sync_translation_keys.py` after adding UI strings to `locales/en.json`
+- Symlinks require normalized paths
+
+## Frontend UI Architecture
+
+### 1. Standalone Web UI
+- Location: `./static/` and `./templates/`
+- Tech: Vanilla JS + CSS, served by standalone server
+- Tests via npm in root directory
+
+### 2. ComfyUI Custom Node Widgets
+- Location: `./web/comfyui/` (Vanilla JS) + `./vue-widgets/` (Vue)
+- Primary styles: `./web/comfyui/lm_styles.css` (NOT `./static/css/`)
+- Vue builds to `./web/comfyui/vue-widgets/`, typecheck via `vue-tsc`

+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Overview
+
+ComfyUI LoRA Manager is a comprehensive LoRA management system for ComfyUI that combines a Python backend with browser-based widgets. It provides model organization, downloading from CivitAI/CivArchive, recipe management, and one-click workflow integration.
+
+## Development Commands
+
+### Backend
+
+```bash
+pip install -r requirements.txt
+pip install -r requirements-dev.txt
+
+# Run standalone server (port 8188 by default)
+python standalone.py --port 8188
+
+# Run all backend tests
+pytest
+
+# Run specific test file or function
+pytest tests/test_recipes.py
+pytest tests/test_recipes.py::test_function_name
+
+# Run backend tests with coverage
+COVERAGE_FILE=coverage/backend/.coverage pytest \
+  --cov=py \
+  --cov=standalone \
+  --cov-report=term-missing \
+  --cov-report=html:coverage/backend/html \
+  --cov-report=xml:coverage/backend/coverage.xml \
+  --cov-report=json:coverage/backend/coverage.json
+```
+
+### Frontend
+
+There are three test suites run by `npm test`: vanilla JS tests (vitest at root) and Vue widget tests (`vue-widgets/` vitest).
+
+```bash
+npm install
+cd vue-widgets && npm install && cd ..
+
+# Run all frontend tests (JS + Vue)
+npm test
+
+# Run only vanilla JS tests
+npm run test:js
+
+# Run only Vue widget tests
+npm run test:vue
+
+# Watch mode (JS tests only)
+npm run test:watch
+
+# Frontend coverage
+npm run test:coverage
+
+# Build Vue widgets (output to web/comfyui/vue-widgets/)
+cd vue-widgets && npm run build
+
+# Vue widget dev mode (watch + rebuild)
+cd vue-widgets && npm run dev
+
+# Typecheck Vue widgets
+cd vue-widgets && npm run typecheck
+```
+
+### Localization
+
+```bash
+# Sync translation keys after UI string updates
+python scripts/sync_translation_keys.py
+```
+
+Locale files are in `locales/` (en, zh-CN, zh-TW, ja, ko, fr, de, es, ru, he).
+
+## Architecture
+
+### Dual Mode Operation
+
+The system runs in two modes:
+- **ComfyUI plugin mode**: Integrates with ComfyUI's PromptServer, uses `folder_paths` for model discovery
+- **Standalone mode**: `standalone.py` mocks ComfyUI dependencies, reads paths from `settings.json`
+- Detection: `os.environ.get("LORA_MANAGER_STANDALONE", "0") == "1"`
+
+### Backend (Python)
+
+**Entry points:**
+- `__init__.py` — ComfyUI plugin entry: registers nodes via `NODE_CLASS_MAPPINGS`, sets `WEB_DIRECTORY`, calls `LoraManager.add_routes()`
+- `standalone.py` — Standalone server: mocks `folder_paths` and node modules, starts aiohttp server
+- `py/lora_manager.py` — Main `LoraManager` class that registers all HTTP routes
+
+**Service layer** (`py/services/`):
+- `ServiceRegistry` singleton for dependency injection; services follow `get_instance()` singleton pattern
+- `BaseModelService` abstract base → `LoraService`, `CheckpointService`, `EmbeddingService`
+- `ModelScanner` base → `LoraScanner`, `CheckpointScanner`, `EmbeddingScanner` for file discovery with hash-based deduplication
+- `PersistentModelCache` — SQLite-based metadata cache
+- `MetadataSyncService` — Background sync from CivitAI/CivArchive APIs
+- `SettingsManager` — Settings with schema migration support
+- `WebSocketManager` — Real-time progress broadcasting
+- `ModelServiceFactory` — Creates the right service for each model type
+- Use cases in `py/services/use_cases/` orchestrate complex business logic (auto-organize, bulk refresh, downloads)
+
+**Routes** (`py/routes/`):
+- Route registrars organize endpoints by domain: `ModelRouteRegistrar`, `RecipeRouteRegistrar`, etc.
+- Request handlers in `py/routes/handlers/` implement route logic
+- API endpoints follow `/loras/*`, `/checkpoints/*`, `/embeddings/*` patterns
+- All routes use aiohttp, return `web.json_response` or `web.Response`
+
+**Recipe system** (`py/recipes/`):
+- `base.py` — Recipe metadata structure
+- `enrichment.py` — Enriches recipes with model metadata
+- `parsers/` — Parsers for PNG metadata, JSON, and workflow formats
+
+**Custom nodes** (`py/nodes/`):
+- Each node class has a `NAME` class attribute used as key in `NODE_CLASS_MAPPINGS`
+- Standard ComfyUI node pattern: `INPUT_TYPES()` classmethod, `RETURN_TYPES`, `FUNCTION`
+- All nodes registered in `__init__.py`
+
+**Configuration** (`py/config.py`):
+- Manages folder paths for models, handles symlink mappings
+- Auto-saves paths to settings.json in ComfyUI mode
+
+### Frontend — Two Distinct UI Systems
+
+#### 1. Standalone Manager Web UI
+- **Location:** `static/` (JS/CSS) and `templates/` (HTML)
+- **Tech:** Vanilla JS + CSS, served by standalone server
+- **Structure:** `static/js/core.js` (shared), `loras.js`, `checkpoints.js`, `embeddings.js`, `recipes.js`, `statistics.js`
+- **Tests:** `tests/frontend/**/*.test.js` (vitest + jsdom)
+
+#### 2. ComfyUI Custom Node Widgets
+- **Vanilla JS widgets:** `web/comfyui/*.js` — ES modules extending ComfyUI's LiteGraph UI
+  - `loras_widget.js` / `loras_widget_events.js` — Main LoRA selection widget
+  - `autocomplete.js` — Trigger word and embedding autocomplete
+  - `preview_tooltip.js` — Model card preview tooltips
+  - `top_menu_extension.js` — "Launch LoRA Manager" menu item
+  - `utils.js` — Shared utilities and API helpers
+  - Widget styling in `web/comfyui/lm_styles.css` (NOT `static/css/`)
+- **Vue widgets:** `vue-widgets/src/` → built to `web/comfyui/vue-widgets/`
+  - Vue 3 + TypeScript + PrimeVue + vue-i18n
+  - Vite build with CSS-injected-by-JS plugin
+  - Components: `LoraPoolWidget`, `LoraRandomizerWidget`, `LoraCyclerWidget`, `AutocompleteTextWidget`
+  - Auto-built on ComfyUI startup via `py/vue_widget_builder.py`
+  - Tests: `vue-widgets/tests/**/*.test.ts` (vitest)
+
+**Widget registration pattern:**
+- Widgets use `app.registerExtension()` and `getCustomWidgets` hooks
+- `node.addDOMWidget(name, type, element, options)` embeds HTML in LiteGraph nodes
+- See `docs/dom_widget_dev_guide.md` for DOMWidget development guide
+
+## Code Style
+
+**Python:**
+- PEP 8, 4-space indentation, English comments only
+- Use `from __future__ import annotations` for forward references
+- Use `TYPE_CHECKING` guard for type-checking-only imports
+- Loggers via `logging.getLogger(__name__)`
+- Custom exceptions in `py/services/errors.py`
+- Async patterns: `async def` for I/O, `@pytest.mark.asyncio` for async tests
+- Singleton pattern with class-level `asyncio.Lock` (see `ModelScanner.get_instance()`)
+
+**JavaScript:**
+- ES modules, camelCase functions/variables, PascalCase classes
+- Widget files use `*_widget.js` suffix
+- Prefer vanilla JS for `web/comfyui/` widgets, avoid framework dependencies (except Vue widgets)
+
+## Testing
+
+**Backend (pytest):**
+- Config in `pytest.ini`: `--import-mode=importlib`, testpaths=`tests`
+- Fixtures in `tests/conftest.py` handle ComfyUI dependency mocking
+- Markers: `@pytest.mark.asyncio`, `@pytest.mark.no_settings_dir_isolation`
+- Uses `tmp_path_factory` for directory isolation
+
+**Frontend (vitest):**
+- Vanilla JS tests: `tests/frontend/**/*.test.js` with jsdom
+- Vue widget tests: `vue-widgets/tests/**/*.test.ts` with jsdom + @vue/test-utils
+- Setup in `tests/frontend/setup.js`
+
+## Key Integration Points
+
+- **Settings:** Stored in user directory (via `platformdirs`) or portable mode (`"use_portable_settings": true`)
+- **CivitAI/CivArchive:** API clients for metadata sync and model downloads; CivitAI API key in settings
+- **Symlink handling:** Config scans symlinks to map virtual→physical paths; fingerprinting prevents redundant rescans
+- **WebSocket:** Broadcasts real-time progress for downloads, scans, and metadata sync
+- **Model scanning flow:** Walk folders → compute hashes → deduplicate → extract safetensors metadata → cache in SQLite → background CivitAI sync → WebSocket broadcast

+The **LoRA Manager Civitai Extension** is a Browser extension designed to work seamlessly with [LoRA Manager](https://github.com/willmiao/ComfyUI-Lora-Manager) to significantly enhance your browsing experience on [Civitai](https://civitai.com). With this extension, you can:
+
+✅ Instantly see which models are already present in your local library  
+✅ Download new models with a single click  
+✅ Manage downloads efficiently with queue and parallel download support  
+✅ Keep your downloaded models automatically organized according to your custom settings    
+
+![Civitai Models page](https://github.com/willmiao/ComfyUI-Lora-Manager/blob/main/wiki-images/civitai-models-page.png) 
+
+**Update:** It now also supports browsing on [CivArchive](https://civarchive.com/) (formerly CivitaiArchive). 
+
+![CivArchive Models page](https://github.com/willmiao/ComfyUI-Lora-Manager/blob/main/wiki-images/civarchive-models-page.png)  
+
+---
+
+## Why Supporter Access?
+
+LoRA Manager is built with love for the Stable Diffusion and ComfyUI communities. Your support makes it possible for me to keep improving and maintaining the tool full-time.
+
+Supporter-exclusive features help ensure the long-term sustainability of LoRA Manager, allowing continuous updates, new features, and better performance for everyone.

+
+For non-Chrome browsers (e.g., Microsoft Edge), you can typically install extensions from the Chrome Web Store by following these steps: open the extension’s Chrome Web Store page, click 'Get extension', then click 'Allow' when prompted to enable installations from other stores, and finally click 'Add extension' to complete the installation.
+
+---
+
+## Privacy & Security
+
+I understand concerns around browser extensions and privacy, and I want to be fully transparent about how the **LM Civitai Extension** works:
+
+- **Reviewed and Verified**  
+  This extension has been **manually reviewed and approved by the Chrome Web Store**. The Firefox version uses the **exact same code** (only the packaging format differs) and has passed **Mozilla’s Add-on review**.
+
+- **Minimal Network Access**  
+  The only external server this extension connects to is:  
+  **`https://willmiao.shop`** — used solely for **license validation**.
+
+  It does **not collect, transmit, or store any personal or usage data**.  
+  No browsing history, no user IDs, no analytics, no hidden trackers.
+
+- **Local-Only Model Detection**  
+  Model detection and LoRA Manager communication all happen **locally** within your browser, directly interacting with your local LoRA Manager backend.
+
+I value your trust and are committed to keeping your local setup private and secure. If you have any questions, feel free to reach out!
+
+---
+
+## How to Use
+
+After installing the extension, you'll automatically receive a **7-day trial** to explore all features.
+
+When the extension is correctly installed and your license is valid:
+
+- Open **Civitai**, and you'll see visual indicators added by the extension on model cards, showing:
+  - ✅ Models already present in your local library  
+  - ⬇️ A download button for models not in your library  
+
+Clicking the download button adds the corresponding model version to the download queue, waiting to be downloaded. You can set up to **5 models to download simultaneously**.
+
+### Visual Indicators Appear On:
+
+- **Home Page** — Featured models  
+- **Models Page**  
+- **Creator Profiles** — If the creator has set their models to be visible  
+- **Recommended Resources** — On individual model pages  
+
+### Version Buttons on Model Pages
+
+On a specific model page, visual indicators also appear on version buttons, showing which versions are already in your local library.
+
+**Starting from v0.4.8**, model pages use a dedicated download button for better compatibility. When switching to a specific version by clicking a version button:
+
+- The new **dedicated download button** directly triggers download via **LoRA Manager**
+- The **original download button** remains unchanged for standard browser downloads
+
+![Civitai Model Page](https://github.com/willmiao/ComfyUI-Lora-Manager/blob/main/wiki-images/civitai-model-page.png)
+
+### Hide Models Already in Library (Beta)
+
+**New in v0.4.8**: A new **Hide models already in library (Beta)** option makes it easier to focus on models you haven't added yet. It can be enabled from Settings, or toggled quickly using **Ctrl + Shift + H** (macOS: **Command + Shift + H**).
+
+### Resources on Image Pages — now shows in-library indicators for image resources plus one-click recipe import
+
+- **One-Click Import Civitai Image as Recipe** — Import any Civitai image as a recipe with a single click in the Resources Used panel.
+- **Auto-Queue Missing Assets** — In Settings you can decide if LoRAs or checkpoints referenced by that image should automatically be added to your download queue.
+- **More Accurate Metadata** — Importing directly from the page is faster than copying inside LM and keeps on-site tags and other metadata perfectly aligned.

+
+---
+
+## Model Download Location & LoRA Manager Settings
+
+To use the **one-click download function**, you must first set:
+
+- Your **Default LoRAs Root**  
+- Your **Default Checkpoints Root**  
+
+These are set within LoRA Manager's settings.
+
+When everything is configured, downloaded model files will be placed in:  
+
+`<Default_Models_Root>/<Base_Model_of_the_Model>/<First_Tag_of_the_Model>`
+
+
+### Update: Default Path Customization (2025-07-21)  
+
+A new setting to customize the default download path has been added in the nightly version. You can now personalize where models are saved when downloading via the LM Civitai Extension.
+
+![Default Path Customization](https://github.com/willmiao/ComfyUI-Lora-Manager/blob/main/wiki-images/default-path-customization.png)
+
+The previous YAML path mapping file will be deprecated—settings will now be unified in settings.json to simplify configuration.
+
+---
+
+## Backend Port Configuration
+
+If your **ComfyUI** or **LoRA Manager** backend is running on a port **other than the default 8188**, you must configure the backend port in the extension's settings.
+
+After correctly setting and saving the port, you'll see in the extension's header area:  
+- A **Healthy** status with the tooltip:  `Connected to LoRA Manager on port xxxx`
+
+
+---
+
+## Advanced Usage
+
+### Connecting to a Remote LoRA Manager
+
+If your LoRA Manager is running on another computer, you can still connect from your browser using port forwarding.
+
+> **Why can't you set a remote IP directly?**
+>
+> For privacy and security, the extension only requests access to `http://127.0.0.1/*`. Supporting remote IPs would require much broader permissions, which may be rejected by browser stores and could raise user concerns.
+
+**Solution: Port Forwarding with `socat`**
+
+On your browser computer, run:
+
+`socat TCP-LISTEN:8188,bind=127.0.0.1,fork TCP:REMOTE.IP.ADDRESS.HERE:8188`
+
+- Replace `REMOTE.IP.ADDRESS.HERE` with the IP of the machine running LoRA Manager.
+- Adjust the port if needed.
+
+This lets the extension connect to `127.0.0.1:8188` as usual, with traffic forwarded to your remote server.
+
+_Thanks to user **Temikus** for sharing this solution!_
+
+---
+
+## Roadmap
+
+The extension will evolve alongside **LoRA Manager** improvements. Planned features include:
+
+- [x] Support for **additional model types** (e.g., embeddings)
+- [x] One-click **Recipe Import**
+- [x] Display of in-library status for all resources in the **Resources Used** section of the image page
+- [x] One-click **Auto-organize Models**
+- [x] **Hide models already in library (Beta)** - Focus on models you haven't added yet
+
+**Stay tuned — and thank you for your support!**

+# Example image route architecture
+
+The example image routing stack mirrors the layered model route stack described in
+[`docs/architecture/model_routes.md`](model_routes.md). HTTP wiring, controller setup,
+handler orchestration, and long-running workflows now live in clearly separated modules so
+we can extend download/import behaviour without touching the entire feature surface.
+
+```mermaid
+graph TD
+    subgraph HTTP
+        A[ExampleImagesRouteRegistrar] -->|binds| B[ExampleImagesRoutes controller]
+    end
+    subgraph Application
+        B --> C[ExampleImagesHandlerSet]
+        C --> D1[Handlers]
+        D1 --> E1[Use cases]

+        F1 --> G2[Model metadata]
+        F1 --> G3[WebSocket progress]
+    end
+```
+
+## Layer responsibilities
+
+| Layer | Module(s) | Responsibility |
+| --- | --- | --- |
+| Registrar | `py/routes/example_images_route_registrar.py` | Declarative catalogue of every example image endpoint plus helpers that bind them to an `aiohttp` router. Keeps HTTP concerns symmetrical with the model registrar. |
+| Controller | `py/routes/example_images_routes.py` | Lazily constructs `ExampleImagesHandlerSet`, injects defaults for the download manager, processor, and file manager, and exposes the registrar-ready mapping just like `BaseModelRoutes`. |
+| Handler set | `py/routes/handlers/example_images_handlers.py` | Groups HTTP adapters by concern (downloads, imports/deletes, filesystem access). Each handler translates domain errors into HTTP responses and defers to a use case or utility service. |
+| Use cases | `py/services/use_cases/example_images/*.py` | Encapsulate orchestration for downloads and imports. They validate input, translate concurrency/configuration errors, and keep handler logic declarative. |
+| Supporting services | `py/utils/example_images_download_manager.py`, `py/utils/example_images_processor.py`, `py/utils/example_images_file_manager.py` | Execute long-running work: pull assets from Civitai, persist uploads, clean metadata, expose filesystem actions with guardrails, and broadcast progress snapshots. |

+
+`ExampleImagesHandlerSet` flattens the handler objects into the `{"handler_name": coroutine}`
+mapping consumed by the registrar. The table below outlines how each handler collaborates
+with the use cases and utilities.
+
+| Handler | Key endpoints | Collaborators | Contracts |
+| --- | --- | --- | --- |
+| `ExampleImagesDownloadHandler` | `/api/lm/download-example-images`, `/api/lm/example-images-status`, `/api/lm/pause-example-images`, `/api/lm/resume-example-images`, `/api/lm/force-download-example-images` | `DownloadExampleImagesUseCase`, `DownloadManager` | Delegates payload validation and concurrency checks to the use case; progress/status endpoints expose the same snapshot used for WebSocket broadcasts; pause/resume surface `DownloadNotRunningError` as HTTP 400 instead of 500. |
+| `ExampleImagesManagementHandler` | `/api/lm/import-example-images`, `/api/lm/delete-example-image` | `ImportExampleImagesUseCase`, `ExampleImagesProcessor` | Multipart uploads are streamed to disk via the use case; validation failures return HTTP 400 with no filesystem side effects; deletion funnels through the processor to prune metadata and cached images consistently. |
+| `ExampleImagesFileHandler` | `/api/lm/open-example-images-folder`, `/api/lm/example-image-files`, `/api/lm/has-example-images` | `ExampleImagesFileManager` | Centralises filesystem access, enforcing settings-based root paths and returning HTTP 400/404 for missing configuration or folders; responses always include `success`/`has_images` booleans for UI consumption. |
+
+## Use case boundaries
+
+| Use case | Entry point | Dependencies | Guarantees |
+| --- | --- | --- | --- |
+| `DownloadExampleImagesUseCase` | `execute(payload)` | `DownloadManager.start_download`, download configuration errors | Raises `DownloadExampleImagesInProgressError` when the manager reports an active job, rewraps configuration errors into `DownloadExampleImagesConfigurationError`, and lets `ExampleImagesDownloadError` bubble as 500s so handlers do not duplicate logging. |
+| `ImportExampleImagesUseCase` | `execute(request)` | `ExampleImagesProcessor.import_images`, temporary file helpers | Supports multipart or JSON payloads, normalises file paths into a single list, cleans up temp files even on failure, and maps validation issues to `ImportExampleImagesValidationError` for HTTP 400 responses. |
+
+## Maintaining critical invariants
+
+* **Shared progress snapshots** - The download handler returns the same snapshot built by
+  `DownloadManager`, guaranteeing parity between HTTP polling endpoints and WebSocket
+  progress events.
+* **Safe filesystem access** - All folder/file actions flow through
+  `ExampleImagesFileManager`, which validates the configured example image root and ensures
+  responses never leak absolute paths outside the allowed directory.
+* **Metadata hygiene** - Import/delete operations run through `ExampleImagesProcessor`,
+  which updates model metadata via `MetadataManager` and notifies the relevant scanners so
+  cache state stays in sync.
+
+## Migration notes
+
+The refactor brings the example image stack in line with the model/recipe stacks:
+
+1. `ExampleImagesRouteRegistrar` now owns the declarative route list. Downstream projects
+   should rely on `ExampleImagesRoutes.to_route_mapping()` instead of manually wiring
+   handler callables.
+2. `ExampleImagesRoutes` caches its `ExampleImagesHandlerSet` just like
+   `BaseModelRoutes`. If you previously instantiated handlers directly, inject custom
+   collaborators via the controller constructor (`download_manager`, `processor`,
+   `file_manager`) to keep test seams predictable.
+3. Tests that mocked `ExampleImagesRoutes.setup_routes` should switch to patching
+   `DownloadExampleImagesUseCase`/`ImportExampleImagesUseCase` at import time. The handlers
+   expect those abstractions to surface validation/concurrency errors, and bypassing them
+   will skip the HTTP-friendly error mapping.
+
+## Extending the stack
+
+1. Add the endpoint to `ROUTE_DEFINITIONS` with a unique `handler_name`.
+2. Expose the coroutine on an existing handler class (or create a new handler and extend
+   `ExampleImagesHandlerSet`).
+3. Wire additional services or factories inside `_build_handler_set` on
+   `ExampleImagesRoutes`, mirroring how the model stack introduces new use cases.
+
+`tests/routes/test_example_images_routes.py` exercises registrar binding, download pause
+flows, and import validations. Use it as a template when introducing new handler
+collaborators or error mappings.

+# Base model route architecture
+
+The model routing stack now splits HTTP wiring, orchestration logic, and
+business rules into discrete layers.  The goal is to make it obvious where a
+new collaborator should live and which contract it must honour.  The diagram
+below captures the end-to-end flow for a typical request:
+
+```mermaid
+graph TD
+    subgraph HTTP
+        A[ModelRouteRegistrar] -->|binds| B[BaseModelRoutes handler proxy]

+        F1 --> G2[Filesystem]
+        F1 --> G3[WebSocket state]
+    end
+```
+
+Every box maps to a concrete module:
+
+| Layer | Module(s) | Responsibility |
+| --- | --- | --- |
+| Registrar | `py/routes/model_route_registrar.py` | Declarative list of routes shared by every model type and helper methods for binding them to an `aiohttp` application. |
+| Route controller | `py/routes/base_model_routes.py` | Constructs the handler graph, injects shared services, exposes proxies that surface `503 Service not ready` when the model service has not been attached. |
+| Handler set | `py/routes/handlers/model_handlers.py` | Thin HTTP adapters grouped by concern (page rendering, listings, mutations, queries, downloads, CivitAI integration, move operations, auto-organize). |
+| Use cases | `py/services/use_cases/*.py` | Encapsulate long-running flows (`DownloadModelUseCase`, `BulkMetadataRefreshUseCase`, `AutoOrganizeUseCase`).  They normalise validation errors and concurrency constraints before returning control to the handlers. |
+| Services | `py/services/*.py` | Existing services and scanners that mutate caches, write metadata, move files, and broadcast WebSocket updates. |
+
+## Handler responsibilities & contracts
+
+`ModelHandlerSet` flattens the handler objects into the exact callables used by
+the registrar.  The table below highlights the separation of concerns within
+the set and the invariants that must hold after each handler returns.
+
+| Handler | Key endpoints | Collaborators | Contracts |
+| --- | --- | --- | --- |
+| `ModelPageView` | `/{prefix}` | `SettingsManager`, `server_i18n`, Jinja environment, `service.scanner` | Template is rendered with `is_initializing` flag when caches are cold; i18n filter is registered exactly once per environment instance. |
+| `ModelListingHandler` | `/api/lm/{prefix}/list` | `service.get_paginated_data`, `service.format_response` | Listings respect pagination query parameters and cap `page_size` at 100; every item is formatted before response. |
+| `ModelManagementHandler` | Mutations (delete, exclude, metadata, preview, tags, rename, bulk delete, duplicate verification) | `ModelLifecycleService`, `MetadataSyncService`, `PreviewAssetService`, `TagUpdateService`, scanner cache/index | Cache state mirrors filesystem changes: deletes prune cache & hash index, preview replacements synchronise metadata and cache NSFW levels, metadata saves trigger cache resort when names change. |
+| `ModelQueryHandler` | Read-only queries (top tags, folders, duplicates, metadata, URLs) | Service query helpers & scanner cache | Outputs always wrapped in `{"success": True}` when no error; duplicate/filename grouping omits empty entries; invalid parameters (e.g. missing `model_root`) return HTTP 400. |
+| `ModelDownloadHandler` | `/api/lm/download-model`, `/download-model-get`, `/download-progress/{id}`, `/cancel-download-get` | `DownloadModelUseCase`, `DownloadCoordinator`, `WebSocketManager` | Payload validation errors become HTTP 400 without mutating download progress cache; early-access failures surface as HTTP 401; successful downloads cache progress snapshots that back both WebSocket broadcasts and polling endpoints. |
+| `ModelCivitaiHandler` | CivitAI metadata routes | `MetadataSyncService`, metadata provider factory, `BulkMetadataRefreshUseCase` | `fetch_all_civitai` streams progress via `WebSocketBroadcastCallback`; version lookups validate model type before returning; local availability fields derive from hash lookups without mutating cache state. |
+| `ModelMoveHandler` | `move_model`, `move_models_bulk` | `ModelMoveService` | Moves execute atomically per request; bulk operations aggregate success/failure per file set. |
+| `ModelAutoOrganizeHandler` | `/api/lm/{prefix}/auto-organize` (GET/POST), `/auto-organize-progress` | `AutoOrganizeUseCase`, `WebSocketProgressCallback`, `WebSocketManager` | Enforces single-flight execution using the shared lock; progress broadcasts remain available to polling clients until explicitly cleared; conflicts return HTTP 409 with a descriptive error. |
+
+## Use case boundaries
+
+Each use case exposes a narrow asynchronous API that hides the underlying
+services.  Their error mapping is essential for predictable HTTP responses.
+
+| Use case | Entry point | Dependencies | Guarantees |
+| --- | --- | --- | --- |
+| `DownloadModelUseCase` | `execute(payload)` | `DownloadCoordinator.schedule_download` | Translates `ValueError` into `DownloadModelValidationError` for HTTP 400, recognises early-access errors (`"401"` in message) and surfaces them as `DownloadModelEarlyAccessError`, forwards success dictionaries untouched. |
+| `AutoOrganizeUseCase` | `execute(file_paths, progress_callback)` | `ModelFileService.auto_organize_models`, `WebSocketManager` lock | Guarded by `ws_manager` lock + status checks; raises `AutoOrganizeInProgressError` before invoking the file service when another run is already active. |
+| `BulkMetadataRefreshUseCase` | `execute_with_error_handling(progress_callback)` | `MetadataSyncService`, `SettingsManager`, `WebSocketBroadcastCallback` | Iterates through cached models, applies metadata sync, emits progress snapshots that handlers broadcast unchanged. |
+
+## Maintaining legacy contracts
+
+The refactor preserves the invariants called out in the previous architecture
+notes.  The most critical ones are reiterated here to emphasise the
+collaboration points:
+
+1. **Cache mutations** – Delete, exclude, rename, and bulk delete operations are
+   channelled through `ModelManagementHandler`.  The handler delegates to
+   `ModelLifecycleService` or `MetadataSyncService`, and the scanner cache is
+   mutated in-place before the handler returns.  The accompanying tests assert
+   that `scanner._cache.raw_data` and `scanner._hash_index` stay in sync after
+   each mutation.
+2. **Preview updates** – `PreviewAssetService.replace_preview` writes the new
+   asset, `MetadataSyncService` persists the JSON metadata, and
+   `scanner.update_preview_in_cache` mirrors the change.  The handler returns
+   the static URL produced by `config.get_preview_static_url`, keeping browser
+   clients in lockstep with disk state.
+3. **Download progress** – `DownloadCoordinator.schedule_download` generates the
+   download identifier, registers a WebSocket progress callback, and caches the
+   latest numeric progress via `WebSocketManager`.  Both `download_model`
+   responses and `/download-progress/{id}` polling read from the same cache to
+   guarantee consistent progress reporting across transports.
+
+## Extending the stack
+
+To add a new shared route:
+
+1. Declare it in `COMMON_ROUTE_DEFINITIONS` using a unique handler name.
+2. Implement the corresponding coroutine on one of the handlers inside
+   `ModelHandlerSet` (or introduce a new handler class when the concern does not
+   fit existing ones).
+3. Inject additional dependencies in `BaseModelRoutes._create_handler_set` by
+   wiring services or use cases through the constructor parameters.
+
+Model-specific routes should continue to be registered inside the subclass
+implementation of `setup_specific_routes`, reusing the shared registrar where
+possible.

+# Multi-Library Management for Standalone Mode
+
+## Requirements Summary
+- **Independent libraries**: In standalone mode, users can maintain multiple libraries, where each library represents a distinct set of model folders (LoRAs, checkpoints, embeddings, etc.). Only one library is active at any given time, but users need a fast way to switch between them.
+- **Library-specific settings**: The fields that vary per library are `folder_paths`, `default_lora_root`, `default_checkpoint_root`, and `default_embedding_root` inside `settings.json`.
+- **Persistent caches**: Every library must have its own SQLite persistent model cache so that metadata generated for one library does not leak into another.
+- **Backward compatibility**: Existing single-library setups should continue to work. When no multi-library configuration is provided, the application should behave exactly as before.
+
+## Proposed Design
+1. **Library registry**
+   - Extend the standalone configuration to hold a list of libraries, each identified by a unique name.
+   - Each entry stores the folder path configuration plus any library-scoped metadata (e.g. creation time, display name).
+   - The active library key is stored separately to allow quick switching without rewriting the full config.
+2. **Settings management**
+   - Update `settings_manager` to load and persist the library registry. When a library is activated, hydrate the in-memory settings object with that library's folder configuration.
+   - Provide helper methods for creating, renaming, and deleting libraries, ensuring validation for duplicate names and path collisions.
+   - Continue writing the active library settings to `settings.json` for compatibility, while storing the registry in a new section such as `libraries`.
+3. **Persistent model cache**
+   - Derive the SQLite file path from the active library, e.g. `model_cache_<library>.sqlite` or a nested directory structure like `model_cache/<library>/models.sqlite`.
+   - Update `PersistentModelCache` so it resolves the database path dynamically whenever the active library changes. Ensure connections are closed before switching to avoid locking issues.
+   - Migrate existing single cache files by treating them as the default library's cache.
+4. **Model scanning workflow**
+   - Modify `ModelScanner` and related services to react to library switches by clearing in-memory caches, re-reading folder paths, and rehydrating metadata from the library-specific SQLite cache.
+   - Provide API endpoints in standalone mode to list libraries, activate one, and trigger a rescan.
+5. **UI/UX considerations**
+   - In the standalone UI, introduce a library selector component that surfaces available libraries and offers quick switching.
+   - Offer feedback when switching libraries (e.g. spinner while rescanning) and guard destructive actions with confirmation prompts.
+
+## Implementation Notes
+- **Data migration**: On startup, detect if the old `settings.json` structure is present. If so, create a default library entry using the current folder paths and point the active library to it.
+- **Thread safety**: Ensure that any long-running scans are cancelled or awaited before switching libraries to prevent race conditions in cache writes.
+- **Testing**: Add unit tests for the settings manager to cover library CRUD operations and cache path resolution. Include integration tests that simulate switching libraries and verifying that the correct models are loaded.
+- **Documentation**: Update user guides to explain how to define libraries, switch between them, and where the new cache files are stored.
+- **Extensibility**: Keep the design open to future per-library settings (e.g. auto-refresh intervals, metadata overrides) by storing library data as objects instead of flat maps.

+
+## Layer responsibilities
+
+| Layer | Module(s) | Responsibility |
+| --- | --- | --- |
+| Registrar | `py/routes/recipe_route_registrar.py` | Declarative list of every recipe endpoint and helper methods that bind them to an `aiohttp` application. |
+| Controller | `py/routes/base_recipe_routes.py`, `py/routes/recipe_routes.py` | Lazily resolves scanners/clients from the service registry, wires shared templates/i18n, instantiates `RecipeHandlerSet`, and exposes a `{handler_name: coroutine}` mapping for the registrar. |
+| Handler set | `py/routes/handlers/recipe_handlers.py` | Thin HTTP adapters grouped by concern (page view, listings, queries, mutations, sharing). They normalise responses and translate service exceptions into HTTP status codes. |
+| Services & scanners | `py/services/recipes/*.py`, `py/services/recipe_scanner.py`, `py/services/service_registry.py` | Concrete business logic: metadata parsing, persistence, sharing, fingerprint/index maintenance, and cache refresh. |
+
+## Handler responsibilities & invariants
+
+`RecipeHandlerSet` flattens purpose-built handler objects into the callables the
+registrar binds. Each handler is responsible for a narrow concern and enforces a
+set of invariants before returning:
+
+| Handler | Key endpoints | Collaborators | Contracts |
+| --- | --- | --- | --- |
+| `RecipePageView` | `/loras/recipes` | `SettingsManager`, `server_i18n`, Jinja environment, recipe scanner getter | Template rendered with `is_initializing` flag when caches are still warming; i18n filter registered exactly once per environment instance. |
+| `RecipeListingHandler` | `/api/lm/recipes`, `/api/lm/recipe/{id}` | `recipe_scanner.get_paginated_data`, `recipe_scanner.get_recipe_by_id` | Listings respect pagination and search filters; every item receives a `file_url` fallback even when metadata is incomplete; missing recipes become HTTP 404. |
+| `RecipeQueryHandler` | Tag/base-model stats, syntax, LoRA lookups | Recipe scanner cache, `format_recipe_file_url` helper | Cache snapshots are reused without forcing refresh; duplicate lookups collapse groups by fingerprint; syntax lookups return helpful errors when LoRAs are absent. |
+| `RecipeManagementHandler` | Save, update, reconnect, bulk delete, widget ingest | `RecipePersistenceService`, `RecipeAnalysisService`, recipe scanner | Persistence results propagate HTTP status codes; fingerprint/index updates flow through the scanner before returning; validation errors surface as HTTP 400 without touching disk. |
+| `RecipeAnalysisHandler` | Uploaded/local/remote analysis | `RecipeAnalysisService`, `civitai_client`, recipe scanner | Unsupported content types map to HTTP 400; download errors (`RecipeDownloadError`) are not retried; every response includes a `loras` array for client compatibility. |
+| `RecipeSharingHandler` | Share + download | `RecipeSharingService`, recipe scanner | Share responses provide a stable download URL and filename; expired shares surface as HTTP 404; downloads stream via `web.FileResponse` with attachment headers. |
+
+## Use case boundaries
+
+The dedicated services encapsulate long-running work so handlers stay thin.
+
+| Use case | Entry point | Dependencies | Guarantees |
+| --- | --- | --- | --- |
+| `RecipeAnalysisService` | `analyze_uploaded_image`, `analyze_remote_image`, `analyze_local_image`, `analyze_widget_metadata` | `ExifUtils`, `RecipeParserFactory`, downloader factory, optional metadata collector/processor | Normalises missing/invalid payloads into `RecipeValidationError`; generates consistent fingerprint data to keep duplicate detection stable; temporary files are cleaned up after every analysis path. |
+| `RecipePersistenceService` | `save_recipe`, `delete_recipe`, `update_recipe`, `reconnect_lora`, `bulk_delete`, `save_recipe_from_widget` | `ExifUtils`, recipe scanner, card preview sizing constants | Writes images/JSON metadata atomically; updates scanner caches and hash indices before returning; recalculates fingerprints whenever LoRA assignments change. |
+| `RecipeSharingService` | `share_recipe`, `prepare_download` | `tempfile`, recipe scanner | Copies originals to TTL-managed temp files; metadata lookups re-use the scanner; expired shares trigger cleanup and `RecipeNotFoundError`. |
+
+## Maintaining critical invariants
+
+* **Cache updates** – Mutations (`save`, `delete`, `bulk_delete`, `update`) call
+  back into the recipe scanner to mutate the in-memory cache and fingerprint
+  index before returning a response. Tests assert that these methods are invoked
+  even when stubbing persistence.
+* **Fingerprint management** – `RecipePersistenceService` recomputes
+  fingerprints whenever LoRA metadata changes and duplicate lookups use those
+  fingerprints to group recipes. Handlers bubble the resulting IDs so clients
+  can merge duplicates without an extra fetch.
+* **Metadata synchronisation** – Saving or reconnecting a recipe updates the
+  JSON sidecar, refreshes embedded metadata via `ExifUtils`, and instructs the
+  scanner to resort its cache. Sharing relies on this metadata to generate
+  filenames and ensure downloads stay in sync with on-disk state.
+
+## Extending the stack
+
+1. Declare the new endpoint in `ROUTE_DEFINITIONS` with a unique handler name.
+2. Implement the coroutine on an existing handler or introduce a new handler
+   class inside `py/routes/handlers/recipe_handlers.py` when the concern does
+   not fit existing ones.
+3. Wire additional collaborators inside
+   `BaseRecipeRoutes._create_handler_set` (inject new services or factories) and
+   expose helper getters on the handler owner if the handler needs to share
+   utilities.
+
+Integration tests in `tests/routes/test_recipe_routes.py` exercise the listing,
+mutation, analysis-error, and sharing paths end-to-end, ensuring the controller
+and handler wiring remains valid as new capabilities are added.

+# Custom Priority Tag Format Proposal
+
+To support user-defined priority tags with flexible aliasing across different model types, the configuration will be stored as editable strings. The format balances readability with enough structure for parsing on both the backend and frontend.
+
+## Format Overview
+
+- Each model type is declared on its own line: `model_type: entries`.
+- Entries are comma-separated and ordered by priority from highest to lowest.
+- An entry may be a single canonical tag (e.g., `realistic`) or a canonical tag with aliases.
+- Canonical tags define the final folder name that should be used when matching that entry.
+- Aliases are enclosed in parentheses and separated by `|` (vertical bar).
+- All matching is case-insensitive; stored canonical names preserve the user-specified casing for folder creation and UI suggestions.
+
+### Grammar
+
+```
+priority-config := model-config { "\n" model-config }
+model-config    := model-type ":" entry-list
+model-type      := <identifier without spaces>
+entry-list      := entry { "," entry }
+entry           := canonical [ "(" alias { "|" alias } ")" ]
+canonical       := <tag text without parentheses or commas>
+alias           := <tag text without parentheses, commas, or pipes>
+```
+
+Examples:
+
+```
+lora: celebrity(celeb|celebrity), stylized, character(char)
+checkpoint: realistic(realism|realistic), anime(anime-style|toon)
+embedding: face, celeb(celebrity|celeb)
+```
+
+## Parsing Notes
+
+- Whitespace around separators is ignored to make manual editing more forgiving.
+- Duplicate canonical tags within the same model type collapse to a single entry; the first definition wins.
+- Aliases map to their canonical tag. When generating folder names, the canonical form is used.
+- Tags that do not match any alias or canonical entry fall back to the first tag in the model's tag list, preserving current behavior.
+
+## Usage
+
+- **Backend:** Convert each model type's string into an ordered list of canonical tags with alias sets. During path generation, iterate by priority order and match tags against both canonical names and their aliases.
+- **Frontend:** Surface canonical tags as suggestions, optionally displaying aliases in tooltips or secondary text. Input validation should warn about duplicate aliases within the same model type.
+
+This format allows users to customize priority tag handling per model type while keeping editing simple and avoiding proliferation of folder names through alias normalization.

+# DOM Widget Value Persistence - Best Practices
+
+## Overview
+
+DOM widgets require different persistence patterns depending on their complexity. This document covers two patterns:
+
+1. **Simple Text Widgets**: DOM element as source of truth (e.g., textarea, input)
+2. **Complex Widgets**: Internal value with `widget.callback` (e.g., LoraPoolWidget, RandomizerWidget)
+
+## Understanding ComfyUI's Built-in Callback Mechanism
+
+When `widget.value` is set (e.g., during workflow load), ComfyUI's `domWidget.ts` triggers this flow:
+
+```typescript
+// From ComfyUI_frontend/src/scripts/domWidget.ts:146-149
+set value(v: V) {
+  this.options.setValue?.(v)      // 1. Update internal state
+  this.callback?.(this.value)     // 2. Notify listeners for UI updates
+}
+```
+
+This means:
+- `setValue()` handles storing the value
+- `widget.callback()` is automatically called to notify the UI
+- You don't need custom callback mechanisms like `onSetValue`
+
+---
+
+## Pattern 1: Simple Text Input Widgets
+
+For widgets where the value IS the DOM element's text content (textarea, input fields).
+
+### When to Use
+
+- Single text input/textarea widgets
+- Value is a simple string
+- No complex state management needed
+
+### Implementation
+
+**main.ts:**
+```typescript
+const widget = node.addDOMWidget(name, type, container, {
+  getValue() {
+    return widget.inputEl?.value ?? ''
+  },
+  setValue(v: string) {
+    if (widget.inputEl) {
+      widget.inputEl.value = v ?? ''
+    }
+  }
+})
+```
+
+**Vue Component:**
+```typescript
+onMounted(() => {
+  if (textareaRef.value) {
+    props.widget.inputEl = textareaRef.value
+  }
+})
+
+onUnmounted(() => {
+  if (props.widget.inputEl === textareaRef.value) {
+    props.widget.inputEl = undefined
+  }
+})
+```
+
+### Why This Works
+
+- Single source of truth: the DOM element
+- `getValue()` reads directly from DOM
+- `setValue()` writes directly to DOM
+- No sync issues between multiple state variables
+
+---
+
+## Pattern 2: Complex Widgets
+
+For widgets with structured data (JSON configs, arrays, objects) where the value cannot be stored in a DOM element.
+
+### When to Use
+
+- Value is a complex object/array (e.g., `{ loras: [...], settings: {...} }`)
+- Multiple UI elements contribute to the value
+- Vue reactive state manages the UI
+
+### Implementation
+
+**main.ts:**
+```typescript
+let internalValue: MyConfig | undefined
+
+const widget = node.addDOMWidget(name, type, container, {
+  getValue() {
+    return internalValue
+  },
+  setValue(v: MyConfig) {
+    internalValue = v
+    // NO custom onSetValue needed - widget.callback is called automatically
+  },
+  serialize: true  // Ensure value is saved with workflow
+})
+```
+
+**Vue Component:**
+```typescript
+const config = ref<MyConfig>(getDefaultConfig())
+
+onMounted(() => {
+  // Set up callback for UI updates when widget.value changes externally
+  // (e.g., workflow load, undo/redo)
+  props.widget.callback = (newValue: MyConfig) => {
+    if (newValue) {
+      config.value = newValue
+    }
+  }
+
+  // Restore initial value if workflow was already loaded
+  if (props.widget.value) {
+    config.value = props.widget.value
+  }
+})
+
+// When UI changes, update widget value
+function onConfigChange(newConfig: MyConfig) {
+  config.value = newConfig
+  props.widget.value = newConfig  // This also triggers callback
+}
+```
+
+### Why This Works
+
+1. **Clear separation**: `internalValue` stores the data, Vue ref manages the UI
+2. **Built-in callback**: ComfyUI calls `widget.callback()` automatically after `setValue()`
+3. **Bidirectional sync**:
+   - External → UI: `setValue()` updates `internalValue`, `callback()` updates Vue ref
+   - UI → External: User interaction updates Vue ref, which updates `widget.value`
+
+---
+
+## Common Mistakes
+
+### ❌ Creating custom callback mechanisms
+
+```typescript
+// Wrong - unnecessary complexity
+setValue(v: MyConfig) {
+  internalValue = v
+  widget.onSetValue?.(v)  // Don't add this - use widget.callback instead
+}
+```
+
+Use the built-in `widget.callback` instead.
+
+### ❌ Using v-model for simple text inputs in DOM widgets
+
+```html
+<!-- Wrong - creates sync issues -->
+<textarea v-model="textValue" />
+
+<!-- Right for simple text widgets -->
+<textarea ref="textareaRef" @input="onInput" />
+```
+
+### ❌ Watching props.widget.value
+
+```typescript
+// Wrong - creates race conditions
+watch(() => props.widget.value, (newValue) => {
+  config.value = newValue
+})
+```
+
+Use `widget.callback` instead - it's called at the right time in the lifecycle.
+
+### ❌ Multiple sources of truth
+
+```typescript
+// Wrong - who is the source of truth?
+let internalValue = ''        // State 1
+const textValue = ref('')     // State 2
+const domElement = textarea   // State 3
+props.widget.value            // State 4
+```
+
+Choose ONE source of truth:
+- **Simple widgets**: DOM element
+- **Complex widgets**: `internalValue` (with Vue ref as derived UI state)
+
+### ❌ Adding serializeValue for simple widgets
+
+```typescript
+// Wrong - getValue/setValue handle serialization
+props.widget.serializeValue = async () => textValue.value
+```
+
+---
+
+## Decision Guide
+
+| Widget Type | Source of Truth | Use `widget.callback` | Example |
+|-------------|-----------------|----------------------|---------|
+| Simple text input | DOM element (`inputEl`) | Optional | AutocompleteTextWidget |
+| Complex config | `internalValue` | Yes, for UI sync | LoraPoolWidget |
+| Vue component widget | Vue ref + `internalValue` | Yes | RandomizerWidget |
+
+---
+
+## Testing Checklist

+- [ ] Load workflow - value restores correctly
+- [ ] Switch workflow - value persists
+- [ ] Reload page - value persists
+- [ ] UI interaction - value updates
+- [ ] Undo/redo - value syncs with UI

+# DOMWidget Development Guide
+
+This document provides a comprehensive guide for developing custom DOMWidgets in ComfyUI using Vanilla JavaScript. DOMWidgets allow you to embed standard HTML elements (div, video, canvas, input, etc.) into ComfyUI nodes while benefitting from the frontend's automatic layout and zoom management.
+
+## 1. Core Concepts
+
+In ComfyUI, a `DOMWidget` extends the default LiteGraph Canvas rendering logic. It maintains an HTML layer on top of the Canvas, making complex interactions and media displays significantly easier to implement than pure Canvas drawing.
+
+### Key APIs
+*   **`app.registerExtension`**: The entry point for registering extensions.
+*   **`getCustomWidgets`**: A hook for defining new widget types associated with specific input types.
+*   **`node.addDOMWidget`**: The core method to add HTML elements to a node.
+
+---
+
+## 2. Basic Structure
+
+A standard custom DOMWidget extension typically follows this structure:
+
+```javascript
+import { app } from "../../scripts/app.js";
+
+app.registerExtension({
+    name: "My.Custom.Extension",
+    async getCustomWidgets() {
+        return {
+            // Define a new widget type named "MY_WIDGET_TYPE"
+            MY_WIDGET_TYPE(node, inputName, inputData, app) {
+                // 1. Create the HTML element
+                const container = document.createElement("div");
+                container.innerHTML = "Hello <b>DOMWidget</b>!";
+                
+                // 2. Setup styles (Optional but recommended)
+                container.style.color = "white";
+                container.style.backgroundColor = "#222";
+                container.style.padding = "5px";
+
+                // 3. Add the DOMWidget and return the result
+                const widget = node.addDOMWidget(inputName, "MY_WIDGET_TYPE", container, {
+                    // Configuration options
+                    getValue() {
+                        return container.innerText;
+                    },
+                    setValue(v) {
+                        container.innerText = v;
+                    }
+                });
+
+                // 4. Return in the standard format
+                return { widget };
+            }
+        };
+    }
+});
+```
+
+---
+
+## ComfyUI Dual Rendering Modes
+
+ComfyUI frontend supports two rendering modes:
+
+| Mode | Description | DOM Structure |
+| :--- | :--- | :--- |
+| **Canvas Mode** | Traditional rendering where widgets are rendered on top of canvas using absolute positioning | Uses `.dom-widget` class on containers |
+| **Vue DOM Mode** | New rendering mode where nodes and widgets are rendered as Vue components | Uses `.lg-node-widget` class on containers with dynamic IDs (e.g., `v-1-0`) |
+
+### Mode Switching
+
+The frontend switches between modes via `LiteGraph.vueNodesMode` boolean:
+- `LiteGraph.vueNodesMode = true` → Vue DOM Mode
+- `LiteGraph.vueNodesMode = false` → Canvas Mode
+
+**Key Behavior**: Mode switching triggers DOM re-rendering WITHOUT page reload. Widget elements are destroyed and recreated, so any event listeners or references to old DOM elements become invalid.
+
+### Testing Mode Switches via Chrome DevTools MCP
+
+```javascript
+// Trigger render mode change
+LiteGraph.vueNodesMode = !LiteGraph.vueNodesMode;
+
+// Force canvas redraw (optional but helps trigger re-render)
+if (app.canvas) {
+    app.canvas.draw(true, true);
+}
+```
+
+### Development Notes
+
+When implementing widgets that attach event listeners or maintain external references:
+1. **Use `node.onRemoved`** to clean up when node is deleted
+2. **Detect DOM changes** by checking if widget input element is still in document: `document.body.contains(inputElement)`
+3. **Poll for mode changes** by watching `LiteGraph.vueNodesMode` and re-initializing when it changes
+4. **Use `loadedGraphNode` hook** for initial setup (guarantees DOM is fully rendered)
+
+
+---
+
+## 3. The `addDOMWidget` API
+
+```javascript
+node.addDOMWidget(name, type, element, options)
+```
+
+### Parameters
+1.  **`name`**: The internal name of the widget (usually matches the input name).
+2.  **`type`**: The type identifier for the widget.
+3.  **`element`**: The actual HTMLElement to embed.
+4.  **`options`**: (Object) Configuration for lifecycle, sizing, and persistence.
+
+### Common `options` Fields
+| Field | Type | Description |
+| :--- | :--- | :--- |
+| `getValue` | `Function` | Defines how to retrieve the widget's value for serialization. |
+| `setValue` | `Function` | Defines how to restore the widget's state from workflow data. |
+| `getMinHeight` | `Function` | Returns the minimum height in pixels. |
+| `getHeight` | `Function` | Returns the preferred height (supports numbers or percentage strings like `"50%"`). |
+| `onResize` | `Function` | Callback triggered when the widget is resized. |
+| `hideOnZoom`| `Boolean` | Whether to hide the DOM element when zoomed out to improve performance (default: `true`). |
+| `selectOn` | `string[]` | Events on the element that should trigger node selection (default: `['focus', 'click']`). |
+
+---
+
+## 4. Size Control
+
+Custom DOMWidgets must actively inform the parent Node of their size requirements to ensure the Node layout is calculated correctly and connection wires remain aligned.
+
+### 4.1 Core Mechanism
+
+Whether in Canvas Mode or Vue Mode, the underlying logic model (`LGraphNode`) calls the widget's `computeLayoutSize` method to determine dimensions. This logic is used to calculate the Node's total size and the position of input/output slots.
+
+### 4.2 Controlling Height
+
+It is recommended to use the `options` parameter to define height behavior.
+
+**Performance Note:** providing `getMinHeight` and `getHeight` via `options` allows the system to skip expensive DOM measurements (`getComputedStyle`) during rendering loop. This significantly improves performance and prevents FPS drops during node resizing.
+
+**Method 1: Using `options` (Recommended)**
+
+```javascript
+const widget = node.addDOMWidget("MyWidget", "custom", element, {
+    // Specify minimum height in pixels
+    getMinHeight: () => 150,
+    
+    // Or specify preferred height (pixels or percentage string)
+    // getHeight: () => "50%", 
+});
+```
+
+**Method 2: Using CSS Variables**
+
+You can also set specific CSS variables on the root element:
+
+```javascript
+element.style.setProperty("--comfy-widget-min-height", "150px");
+// or --comfy-widget-height
+```
+
+### 4.3 Controlling Width
+
+By default, a DOMWidget's width automatically stretches to fit the Node's width (which is determined by the Title or other Input Slots).
+
+If you must **force the Node to be wider** to accommodate your widget, you need to override the widget instance's `computeLayoutSize` method:
+
+```javascript
+const widget = node.addDOMWidget("WideWidget", "custom", element);
+
+// Override the default layout calculation
+widget.computeLayoutSize = (targetNode) => {
+    return {
+        minHeight: 150, // Must return height
+        minWidth: 300   // Force the Node to be at least 300px wide
+    };
+};
+```
+
+### 4.4 Dynamic Resizing
+
+If your widget's content changes dynamically (e.g., expanding sections, loading images, or CSS changes), the DOM element will resize, but the Canvas-rendered Node background and Slots will not automatically follow. You must manually trigger a synchronization.
+
+**The Update Sequence:**
+Whenever the **actual rendering height** of your DOM element changes, execute the following "three-step combo":
+
+```javascript
+// 1. Calculate the new optimal size for the node based on current widget requirements
+const newSize = node.computeSize();
+
+// 2. Apply the new size to the node model (updates bounding box and slot positions)
+node.setSize(newSize);
+
+// 3. Mark the canvas as dirty to trigger a redraw in the next animation frame
+node.setDirtyCanvas(true, true);
+```
+
+**Common Scenarios:**
+
+| Scenario | Actual Height Change? | Update Required? |
+| :--- | :--- | :--- |
+| **Expand/Collapse content** | **Yes** | ✅ **Yes**. Prevents widget from overflowing node boundaries. |
+| **Image/Video finished loading** | **Yes** | ✅ **Yes**. Initial height might be 0 until the media loads. |
+| **Changing `minHeight`** | **Maybe** | ❓ **Only if** the change causes the element's actual height to shift. |
+| **Changing font size/styles** | **Yes** | ✅ **Yes**. Text reflow often changes the total height. |
+| **User dragging node corner** | **Yes** | ❌ **No**. LiteGraph handles this internally. |
+
+---
+
+## 5. State Persistence (Serialization)
+
+### 5.1 Default Behavior
+
+DOMWidgets have **serialization enabled** by default (`serialize` property is `true`).
+*   **Saving**: ComfyUI attempts to read the widget's value to save into the Workflow file.
+*   **Loading**: ComfyUI reads the value from the Workflow file and assigns it to the widget.
+
+### 5.2 Custom Serialization
+
+To make persistence work effectively (saving internal DOM state and restoring it), you must implement `getValue` and `setValue` in the `options`:
+
+*   **`getValue`**: Returns the state to be saved (Number, String, or Object).
+*   **`setValue`**: Receives the restored value and updates the DOM element.
+
+**Example:**
+
+```javascript
+const inputEl = document.createElement("input");
+const widget = node.addDOMWidget("MyInput", "custom", inputEl, {
+    // 1. Called during Save
+    getValue: () => {
+        return inputEl.value;
+    },
+    // 2. Called during Load or Copy/Paste
+    setValue: (value) => {
+        inputEl.value = value || "";
+    }
+});
+
+// Optional: Listen for changes to update widget.value immediately
+inputEl.addEventListener("change", () => {
+    widget.value = inputEl.value; // Triggers callbacks
+});
+```
+
+> **⚠️ Important**: For Vue-based DOM widgets with text inputs, follow the [Value Persistence Best Practices](dom-widgets/value-persistence-best-practices.md) to avoid sync issues. Key takeaway: use DOM element as single source of truth, avoid internal state variables and v-model.
+
+### 5.3 The Restoration Mechanism (`configure`)
+
+*   **`configure(data)`**: When a Workflow is loaded, `LGraphNode` calls its `configure(data)` method.
+*   **`setValue` Chain**: During `configure`, the Node iterates over the saved `widgets_values` array and assigns each value (`widget.value = savedValue`). For DOMWidgets, this assignment triggers the `setValue` callback defined in your options.
+
+Therefore, `options.setValue` is the critical hook for restoring widget state.
+
+### 5.4 Disabling Serialization
+
+If your widget is purely for display (e.g., a real-time monitor or generated chart) and doesn't need to save state, disable serialization to reduce workflow file size.
+
+**Note**: You cannot set this via `options`. You must modify the widget instance directly.
+
+```javascript
+const widget = node.addDOMWidget("DisplayOnly", "custom", element);
+widget.serialize = false; // Explicitly disable
+```
+
+---
+
+## 6. Lifecycle & Events
+
+### 6.1 `onResize`
+
+When the Node size changes (e.g., user drags the corner), the widget can receive a notification via `options`:
+
+```javascript
+const widget = node.addDOMWidget("ResizingWidget", "custom", element, {
+    onResize: (w) => {
+        // 'w' is the widget instance
+        // Adjust internal DOM layout here if necessary
+        console.log("Widget resized");
+    }
+});
+```
+
+### 6.2 Construction & Mounting
+
+*   **Construction**: Occurs immediately when `addDOMWidget` is called.
+*   **Mounting**:
+    *   **Canvas Mode**: Appended to `.dom-widget-container` via `DomWidget.vue`.
+    *   **Vue Mode**: Appended inside the Node component via `WidgetDOM.vue`.
+    *   **Caution**: When `addDOMWidget` returns, the element may not be in the `document.body` yet. If you need to access layout properties like `getBoundingClientRect`, use `setTimeout` or wait for the first `onResize`.
+
+### 6.3 Cleanup
+
+If you create external references (like `setInterval` or global event listeners), ensure you clean them up using `node.onRemoved`:
+
+```javascript
+node.onRemoved = function() {
+    clearInterval(myInterval);
+    // Call original onRemoved if it existed
+};
+```
+
+---
+
+## 7. Styling & Best Practices
+
+### 7.1 Styling
+Since DOMWidgets are placed in absolute positioned containers or managed by Vue, ensure your container handles sizing gracefully:
+
+```javascript
+container.style.width = "100%";
+container.style.boxSizing = "border-box";
+```
+
+### 7.2 Path References
+When importing `app`, adjust the path based on your extension's folder depth. Typically:
+`import { app } from "../../scripts/app.js";`
+
+### 7.3 Security
+If setting `innerHTML` dynamically, ensure the content is sanitized or trusted to prevent XSS attacks.
+
+### 7.4 UI Constraints for ComfyUI Custom Node Widgets
+
+When developing DOMWidgets as internal UI widgets for ComfyUI custom nodes, keep the following constraints in mind:
+
+#### 7.4.1 Minimize Vertical Space
+
+ComfyUI nodes are often displayed in a compact graph view with many nodes visible simultaneously. Avoid excessive vertical spacing that could clutter the workspace.
+
+- Keep layouts compact and efficient
+- Use appropriate padding and margins (4-8px typically)
+- Stack related controls vertically but avoid unnecessary spacing
+
+#### 7.4.2 Avoid Dynamic Height Changes
+
+Dynamic height changes (expand/collapse sections, showing/hiding content) can cause node layout recalculations and affect connection wire positioning.
+
+- Prefer static layouts over expandable/collapsible sections
+- Use tooltips or overlays for additional information instead
+- If dynamic height is unavoidable, manually trigger layout updates (see Section 4.4)
+
+#### 7.4.3 Keep UI Simple and Intuitive
+
+As internal widgets for ComfyUI custom nodes, the UI should be accessible to users without technical implementation details.
+
+- Use clear, user-friendly terminology (avoid "frontend/backend roll" in favor of "fixed/always randomize")
+- Focus on user intent rather than implementation details
+- Avoid complex interactions that may confuse users
+
+#### 7.4.4 Forward Middle Mouse Events to Canvas
+
+By default, when a DOM widget receives pointer events (e.g., mouse clicks, drags), these events are captured by the widget and not forwarded to the ComfyUI canvas. This prevents users from panning the workflow using the middle mouse button when the cursor is over a DOM widget.
+
+To enable workflow panning over your widget, you should forward middle mouse events (button 1) to the canvas using the `forwardMiddleMouseToCanvas` utility function:
+
+```javascript
+import { forwardMiddleMouseToCanvas } from "./utils.js";
+
+// In your widget creation function
+const container = document.createElement("div");
+container.style.width = "100%";
+container.style.height = "100%";
+// ... other styles ...
+
+// Forward middle mouse events to canvas for panning
+forwardMiddleMouseToCanvas(container);
+
+const widget = node.addDOMWidget(name, type, container, { ... });
+```
+
+The `forwardMiddleMouseToCanvas` function:
+- Forwards `pointerdown` events with button 1 (middle mouse button) to `app.canvas.processMouseDown`
+- Forwards `pointermove` events while middle mouse button is pressed to `app.canvas.processMouseMove`
+- Forwards `pointerup` events with button 1 to `app.canvas.processMouseUp`
+
+This allows users to pan the workflow canvas even when their mouse cursor is hovering over your DOM widget.
+
+---
+
+## 8. Event Handling in Vue DOM Render Mode
+
+ComfyUI frontend supports two rendering modes for nodes:
+- **Legacy Canvas Mode**: Traditional rendering where widgets are rendered on top of the canvas using absolute positioning
+- **Vue DOM Render Mode**: New rendering mode where nodes and widgets are rendered as Vue components
+
+In Vue DOM render mode, event handling works differently. The frontend uses `useCanvasInteractions` composable to manage event forwarding to the canvas. This can cause custom event handlers in your widgets (e.g., mouse wheel for sliders, custom drag operations) to be intercepted by the canvas.
+
+### 8.1 Wheel Event Handling
+
+By default in Vue DOM render mode, wheel events on widgets may be forwarded to the canvas for workflow zoom, overriding your custom wheel handlers (e.g., adjusting slider values with mouse wheel).
+
+To fix this, use the `data-capture-wheel="true"` attribute on elements that should capture wheel events:
+
+```vue
+<!-- Vue component template -->
+<div class="my-slider" data-capture-wheel="true" @wheel="onWheel">
+  <!-- Slider content -->
+</div>
+
+<script setup lang="ts">
+const onWheel = (event: WheelEvent) => {
+  event.preventDefault()
+  // Custom wheel handling logic here
+}
+</script>
+```
+
+**How it works:**
+- ComfyUI's `useCanvasInteractions.ts` checks `target?.closest('[data-capture-wheel="true"]')` before forwarding wheel events
+- If an element (or its ancestor) has this attribute, wheel events are not forwarded to canvas
+- Your custom `@wheel` handler will work as expected
+
+**Granular control:**
+- Apply `data-capture-wheel="true"` to specific interactive elements (e.g., sliders, scrollable areas)
+- Widget container without this attribute will allow workflow zoom when wheel is used elsewhere
+- This allows users to both: adjust widget values with wheel, and zoom workflow with wheel in widget's non-interactive areas
+
+**Example from DualRangeSlider.vue:**
+```vue
+<template>
+  <div
+    class="dual-range-slider"
+    :class="{ disabled, 'is-dragging': dragging !== null }"
+    data-capture-wheel="true"
+    @wheel="onWheel"
+  >
+    <!-- Slider tracks and handles -->
+  </div>
+</template>
+```
+
+### 8.2 Pointer Event Handling
+
+In Vue DOM render mode, pointer events (click, drag, etc.) may also be captured by the canvas system. For custom drag operations:
+
+1. **Use event modifiers to stop propagation:**
+   ```vue
+   <div
+     @pointerdown.stop="startDrag"
+     @pointermove.stop="onDrag"
+     @pointerup.stop="stopDrag"
+   >
+   ```
+
+2. **Use pointer capture for reliable drag tracking:**
+   ```javascript
+   const startDrag = (event: PointerEvent) => {
+     const target = event.currentTarget as HTMLElement
+     target.setPointerCapture(event.pointerId)
+     // ... drag initialization
+   }
+
+   const stopDrag = (event: PointerEvent) => {
+     const target = event.currentTarget as HTMLElement
+     target.releasePointerCapture(event.pointerId)
+     // ... drag cleanup
+   }
+   ```
+
+3. **Use `touch-action: none` CSS for touch devices:**
+   ```css
+   .my-draggable {
+     touch-action: none;
+   }
+   ```
+
+### 8.3 Compatibility Checklist
+
+Ensure your widget works in both rendering modes:
+
+| Feature | Canvas Mode | Vue DOM Mode | Solution |
+|---------|-------------|--------------|----------|
+| Mouse wheel on sliders | Works by default | Needs `data-capture-wheel` | Add `data-capture-wheel="true"` to slider elements |
+| Custom drag operations | Works with `stopPropagation()` | Needs `stopPropagation()` | Use `.stop` modifier and pointer capture |
+| Middle mouse panning | Manual forwarding required | Manual forwarding required | Use `forwardMiddleMouseToCanvas()` |
+| Workflow zoom on widget edges | Works by default | Works by default | No action needed (works by default) |
+
+### 8.4 Testing Recommendations
+
+Test your widget in both rendering modes:
+1. Toggle between Canvas Mode and Vue DOM Mode in ComfyUI settings
+2. Verify custom interactions (wheel, drag, etc.) work in both modes
+3. Verify canvas interactions (zoom, pan) still work when cursor is over non-interactive widget areas
+4. Test with touch devices if applicable
+
+---
+
+## 9. Complete Example: Text Counter
+
+This example implements a simple widget that displays the character count of another text widget in the same node.
+
+```javascript
+import { app } from "../../scripts/app.js";
+
+app.registerExtension({
+    name: "Comfy.TextCounter",
+    getCustomWidgets() {
+        return {
+            TEXT_COUNTER(node, inputName) {
+                const el = document.createElement("div");
+                Object.assign(el.style, {
+                    background: "#222",
+                    border: "1px solid #444",
+                    padding: "8px",
+                    borderRadius: "4px",
+                    fontSize: "12px",
+                    color: "#eee"
+                });
+                
+                const label = document.createElement("span");
+                label.innerText = "Characters: 0";
+                el.appendChild(label);
+
+                const widget = node.addDOMWidget(inputName, "TEXT_COUNTER", el, {
+                    getValue() { return ""; }, // Nothing to save
+                    setValue(v) { },           // Nothing to restore
+                    getMinHeight() { return 40; }
+                });
+                
+                // Disable serialization for this display-only widget
+                widget.serialize = false;
+
+                // Custom method to update UI
+                widget.updateCount = (text) => {
+                    label.innerText = `Characters: ${text.length}`;
+                };
+
+                return { widget };
+            }
+        };
+    },
+    nodeCreated(node) {

+# Recipe Batch Import Feature Requirements
+
+## Overview
+Enable users to import multiple images as recipes in a single operation, rather than processing them individually. This feature addresses the need for efficient bulk recipe creation from existing image collections.
+
+## User Stories
+
+### US-1: Directory Batch Import
+As a user with a folder of reference images or workflow screenshots, I want to import all images from a directory at once so that I don't have to import them one by one.
+
+**Acceptance Criteria:**
+- User can specify a local directory path containing images
+- System discovers all supported image files in the directory
+- Each image is analyzed for metadata and converted to a recipe
+- Results show which images succeeded, failed, or were skipped
+
+### US-2: URL Batch Import
+As a user with a list of image URLs (e.g., from Civitai or other sources), I want to import multiple images by URL in one operation.
+
+**Acceptance Criteria:**
+- User can provide multiple image URLs (one per line or as a list)
+- System downloads and processes each image
+- URL-specific metadata (like Civitai info) is preserved when available
+- Failed URLs are reported with clear error messages
+
+### US-3: Concurrent Processing Control
+As a user with varying system resources, I want to control how many images are processed simultaneously to balance speed and system load.
+
+**Acceptance Criteria:**
+- User can configure the number of concurrent operations (1-10)
+- System provides sensible defaults based on common hardware configurations
+- Processing respects the concurrency limit to prevent resource exhaustion
+
+### US-4: Import Results Summary
+As a user performing a batch import, I want to see a clear summary of the operation results so I understand what succeeded and what needs attention.
+
+**Acceptance Criteria:**
+- Total count of images processed is displayed
+- Number of successfully imported recipes is shown
+- Number of failed imports with error details is provided
+- Number of skipped images (no metadata) is indicated
+- Results can be exported or saved for reference
+
+### US-5: Progress Visibility
+As a user importing a large batch, I want to see the progress of the operation so I know it's working and can estimate completion time.
+
+**Acceptance Criteria:**
+- Progress indicator shows current status (e.g., "Processing image 5 of 50")
+- Real-time updates as each image completes
+- Ability to view partial results before completion
+- Clear indication when the operation is finished
+
+## Functional Requirements
+
+### FR-1: Image Discovery
+The system shall discover image files in a specified directory recursively or non-recursively based on user preference.
+
+**Supported formats:** JPG, JPEG, PNG, WebP, GIF, BMP
+
+### FR-2: Metadata Extraction
+For each image, the system shall:
+- Extract EXIF metadata if present
+- Parse embedded workflow data (ComfyUI PNG metadata)
+- Fetch external metadata for known URL patterns (e.g., Civitai)
+- Generate recipes from extracted information
+
+### FR-3: Concurrent Processing
+The system shall support concurrent processing of multiple images with:
+- Configurable concurrency limit (default: 3)
+- Resource-aware execution
+- Graceful handling of individual failures without stopping the batch
+
+### FR-4: Error Handling
+The system shall handle various error conditions:
+- Invalid directory paths
+- Inaccessible files
+- Network errors for URL imports
+- Images without extractable metadata
+- Malformed or corrupted image files
+
+### FR-5: Recipe Persistence
+Successfully analyzed images shall be persisted as recipes with:
+- Extracted generation parameters
+- Preview image association
+- Tags and metadata
+- Source information (file path or URL)
+
+## Non-Functional Requirements
+
+### NFR-1: Performance
+- Batch operations should complete in reasonable time (< 5 seconds per image on average)
+- UI should remain responsive during batch operations
+- Memory usage should scale gracefully with batch size
+
+### NFR-2: Scalability
+- Support batches of 1-1000 images
+- Handle mixed success/failure scenarios gracefully
+- No hard limits on concurrent operations (configurable)
+
+### NFR-3: Usability
+- Clear error messages for common failure cases
+- Intuitive UI for configuring import options
+- Accessible from the main Recipes interface
+
+### NFR-4: Reliability
+- Failed individual imports should not crash the entire batch
+- Partial results should be preserved on unexpected termination
+- All operations should be idempotent (re-importing same image doesn't create duplicates)
+
+## API Requirements
+
+### Batch Import Endpoints
+The system should expose endpoints for:
+
+1. **Directory Import**
+   - Accept directory path and configuration options
+   - Return operation ID for status tracking
+   - Async or sync operation support
+
+2. **URL Import**
+   - Accept list of URLs and configuration options
+   - Support URL validation before processing
+   - Return operation ID for status tracking
+
+3. **Status/Progress**
+   - Query operation status by ID
+   - Get current progress and partial results
+   - Retrieve final results after completion
+
+## UI/UX Requirements
+
+### UIR-1: Entry Point
+Batch import should be accessible from the Recipes page via a clearly labeled button in the toolbar.
+
+### UIR-2: Import Modal
+A modal dialog should provide:
+- Tab or section for Directory import
+- Tab or section for URL import
+- Configuration options (concurrency, options)
+- Start/Stop controls
+- Results display area
+
+### UIR-3: Results Display
+Results should be presented with:
+- Summary statistics (total, success, failed, skipped)
+- Expandable details for each category
+- Export or copy functionality for results
+- Clear visual distinction between success/failure/skip
+
+## Future Considerations
+
+- **Scheduled Imports**: Ability to schedule batch imports for later execution
+- **Import Templates**: Save import configurations for reuse
+- **Cloud Storage**: Import from cloud storage services (Google Drive, Dropbox)
+- **Duplicate Detection**: Advanced duplicate detection based on image hash
+- **Tag Suggestions**: AI-powered tag suggestions for imported recipes
+- **Batch Editing**: Apply tags or organization to multiple imported recipes at once
+
+## Dependencies
+
+- Recipe analysis service (metadata extraction)
+- Recipe persistence service (storage)
+- Image download capability (for URL imports)
+- Recipe scanner (for refresh after import)
+- Civitai client (for enhanced URL metadata)

+# Frontend DOM Fixture Strategy
+
+This guide outlines how to reproduce the markup emitted by the Django templates while running Vitest in jsdom.  The aim is to make it straightforward to write integration-style unit tests for managers and UI helpers without having to duplicate template fragments inline.
+
+## Loading Template Markup
+
+Vitest executes inside Node, so we can read the same HTML templates that ship with the extension:
+
+1. Use the helper utilities from `tests/frontend/utils/domFixtures.js` to read files under the `templates/` directory.
+2. Mount the returned markup into `document.body` (or any custom container) before importing the module under test so its query selectors resolve correctly.
+
+```js
+import { renderTemplate } from '../utils/domFixtures.js'; // adjust the relative path to your spec
+
+beforeEach(() => {
+  renderTemplate('loras.html', {
+    dataset: { page: 'loras' }
+  });
+});
+```
+
+The helper ensures the dataset is applied to the container, which mirrors how Django sets `data-page` in production.
+
+## Working with Partial Components
+
+Many features are implemented as template partials located under `templates/components/`.  When a test only needs a fragment (for example, the progress panel or context menu markup), load the component file directly:
+
+```js
+const container = renderTemplate('components/progress_panel.html');
+
+const progressPanel = container.querySelector('#progress-panel');
+```
+
+This pattern avoids hand-written fixture strings and keeps the tests aligned with the actual markup.
+
+## Resetting Between Tests
+
+The shared Vitest setup clears `document.body` and storage APIs before each test.  If a suite adds additional DOM nodes outside of the body or needs to reset custom attributes mid-test, use `resetDom()` exported from `domFixtures.js`.
+
+```js
+import { resetDom } from '../utils/domFixtures.js';
+
+afterEach(() => {
+  resetDom();
+});
+```
+
+## Future Enhancements
+
+- Provide typed helpers for injecting mock script tags (e.g., replicating ComfyUI globals).
+- Compose higher-level fixtures that mimic specific pages (loras, checkpoints, recipes) once those managers receive dedicated suites.

+# LoRA & Checkpoints Filtering/Sorting Test Matrix
+
+This matrix captures the scenarios that Phase 3 frontend tests should cover for the LoRA and Checkpoint managers. It focuses on how search, filter, sort, and duplicate badge toggles interact so future specs can share fixtures and expectations.
+
+## Scope
+
+- **Components**: `PageControls`, `FilterManager`, `SearchManager`, and `ModelDuplicatesManager` wiring invoked through `CheckpointsPageManager` and `LorasPageManager`.
+- **Templates**: `templates/loras.html` and `templates/checkpoints.html` along with shared filter panel and toolbar partials.
+- **APIs**: Requests issued through `baseModelApi.fetchModels` (via `resetAndReload`/`refreshModels`) and duplicates badge updates.
+
+## Shared Setup Considerations
+
+1. Render full page templates using `renderLorasPage` / `renderCheckpointsPage` helpers before importing modules so DOM queries resolve.
+2. Stub storage helpers (`getStorageItem`, `setStorageItem`, `getSessionItem`, `setSessionItem`) to observe persistence behavior without mutating real storage.
+3. Mock `sidebarManager` to capture refresh calls triggered after sort/filter actions.
+4. Provide fake API implementations exposing `resetAndReload`, `refreshModels`, `fetchFromCivitai`, `toggleBulkMode`, and `clearCustomFilter` so control events remain asynchronous but deterministic.
+5. Supply a minimal `ModelDuplicatesManager` mock exposing `toggleDuplicateMode`, `checkDuplicatesCount`, and `updateDuplicatesBadgeAfterRefresh` to validate duplicate badge wiring.
+
+## Scenario Matrix
+
+| ID | Feature | Scenario | LoRAs Expectations | Checkpoints Expectations | Notes |
+| --- | --- | --- | --- | --- | --- |
+| F-01 | Search filter | Typing a query updates `pageState.filters.search`, persists to session, and triggers `resetAndReload` on submit | Validate `SearchManager` writes query and reloads via API stub; confirm LoRA cards pass query downstream | Same as LoRAs | Cover `enter` press and clicking search icon |
+| F-02 | Tag filter | Selecting a tag chip cycles include ➜ exclude ➜ clear, updates storage, and reloads results | Tag state stored under `filters.tags[tagName] = 'include'|'exclude'`; `FilterManager.applyFilters` persists and triggers `resetAndReload(true)` | Same; ensure base model tag set is scoped to checkpoints dataset | Include removal path |
+| F-03 | Base model filter | Toggling base model checkboxes updates `filters.baseModel`, persists, and reloads | Ensure only LoRA-supported models show; toggle multi-select | Ensure SDXL/Flux base models appear as expected | Capture UI state restored from storage on next init |
+| F-04 | Favorites-only | Clicking favorites toggle updates session flag and calls `resetAndReload(true)` | Button gains `.active` class and API called | Same | Verify duplicates badge refresh when active |
+| F-05 | Sort selection | Changing sort select saves preference (legacy + new format) and reloads | Confirm `PageControls.saveSortPreference` invoked with option and API called | Same with checkpoints-specific defaults | Cover `convertLegacySortFormat` branch |
+| F-06 | Filter persistence | Re-initializing manager loads stored filters/sort and updates DOM | Filters pre-populate chips/checkboxes; favorites state restored | Same | Requires simulating repeated construction |
+| F-07 | Combined filters | Applying search + tag + base model yields aggregated query params for fetch | Assert API receives merged filter payload | Same | Validate toast messaging for active filters |
+| F-08 | Clearing filters | Using "Clear filters" resets state, storage, and reloads list | `FilterManager.clearFilters` empties `filters`, removes active class, shows toast | Same | Ensure favorites-only toggle unaffected |
+| F-09 | Duplicate badge toggle | Pressing "Find duplicates" toggles duplicate mode and updates badge counts post-refresh | `ModelDuplicatesManager.toggleDuplicateMode` invoked and badge refresh called after API rebuild | Same plus checkpoint-specific duplicate badge dataset | Connects to future duplicate-specific specs |
+| F-10 | Bulk actions menu | Opening bulk dropdown keeps filters intact and closes on outside click | Validate dropdown class toggling and no unintended reload | Same | Guard against regression when dropdown interacts with filters |
+
+## Automation Coverage Status
+
+- ✅ F-01 Search filter, F-02 Tag filter, F-03 Base model filter, F-04 Favorites-only toggle, F-05 Sort selection, and F-09 Duplicate badge toggle are covered by `tests/frontend/components/pageControls.filtering.test.js` for both LoRA and checkpoint pages.
+- ⏳ F-06 Filter persistence, F-07 Combined filters, F-08 Clearing filters, and F-10 Bulk actions remain to be automated alongside upcoming bulk mode refinements.
+
+## Coverage Gaps & Follow-Ups
+
+- Write Vitest suites that exercise the matrix for both managers, sharing fixtures through page helpers to avoid duplication.
+- Capture API parameter assertions by inspecting `baseModelApi.fetchModels` mocks rather than relying solely on state mutations.
+- Add regression cases for legacy storage migrations (old filter keys) once fixtures exist for older payloads.
+- Extend duplicate badge coverage with scenarios where `checkDuplicatesCount` signals zero duplicates versus pending calculations.

+# Library Switching and Preview Routes
+
+Library switching no longer requires restarting the backend. The preview
+thumbnails shown in the UI are now served through a dynamic endpoint that
+resolves files against the folders registered for the active library at request
+time. This allows the multi-library flow to update model roots without touching
+the aiohttp router, so previews remain available immediately after a switch.
+
+## How the dynamic preview endpoint works
+
+* `config.get_preview_static_url()` now returns `/api/lm/previews?path=<encoded>`
+  for any preview path. The raw filesystem location is URL encoded so that it
+  can be passed through the query string without leaking directory structure in
+  the route itself.【F:py/config.py†L398-L404】
+* `PreviewRoutes` exposes the `/api/lm/previews` handler which validates the
+  decoded path against the directories registered for the current library. The
+  request is rejected if it falls outside those roots or if the file does not
+  exist.【F:py/routes/preview_routes.py†L5-L21】【F:py/routes/handlers/preview_handlers.py†L9-L48】
+* `Config` keeps an up-to-date cache of allowed preview roots. Every time a
+  library is applied the cache is rebuilt using the declared LoRA, checkpoint
+  and embedding directories (including symlink targets). The validation logic
+  checks preview requests against this cache.【F:py/config.py†L51-L68】【F:py/config.py†L180-L248】【F:py/config.py†L332-L346】
+
+Both the ComfyUI runtime (`LoraManager.add_routes`) and the standalone launcher
+(`StandaloneLoraManager.add_routes`) register the new preview routes instead of
+mounting a static directory per root. Switching libraries therefore works
+without restarting the application, and preview URLs generated before or after a
+switch continue to resolve correctly.【F:py/lora_manager.py†L21-L82】【F:standalone.py†L302-L315】

+# Priority Tags Configuration Guide
+
+This guide explains how to tailor the tag priority order that powers folder naming and tag suggestions in the LoRA Manager. You only need to edit the comma-separated list of entries shown in the **Priority Tags** field for each model type.
+
+## 1. Pick the Model Type
+
+In the **Priority Tags** dialog you will find one tab per model type (LoRA, Checkpoint, Embedding). Select the tab you want to update; changes on one tab do not affect the others.
+
+## 2. Edit the Entry List
+
+Inside the textarea you will see a line similar to:
+
+```
+character, concept, style(toon|toon_style)
+```
+
+This entire line is the **entry list**. Replace it with your own ordered list.
+
+### Entry Rules
+
+Each entry is separated by a comma, in order from highest to lowest priority:
+
+- **Canonical tag only:** `realistic`
+- **Canonical tag with aliases:** `character(char|chars)`
+
+Aliases live inside `()` and are separated with `|`. The canonical name is what appears in folder names and UI suggestions when any of the aliases are detected. Matching is case-insensitive.
+
+## Use `{first_tag}` in Path Templates
+
+When your path template contains `{first_tag}`, the app picks a folder name based on your priority list and the model’s own tags:
+
+- It checks the priority list from top to bottom. If a canonical tag or any of its aliases appear in the model tags, that canonical name becomes the folder name.
+- If no priority tags are found but the model has tags, the very first model tag is used.
+- If the model has no tags at all, the folder falls back to `no tags`.
+
+### Example
+
+With a template like `/{model_type}/{first_tag}` and the priority entry list `character(char|chars), style(anime|toon)`:
+
+| Model Tags | Folder Name | Why |
+| --- | --- | --- |
+| `["chars", "female"]` | `character` | `chars` matches the `character` alias, so the canonical wins. |
+| `["anime", "portrait"]` | `style` | `anime` hits the `style` entry, so its canonical label is used. |
+| `["portrait", "bw"]` | `portrait` | No priority match, so the first model tag is used. |
+| `[]` | `no tags` | Nothing to match, so the fallback is applied. |
+
+## 3. Save the Settings
+
+After editing the entry list, press **Enter** to save. Use **Shift+Enter** whenever you need a new line. Clicking outside the field also saves automatically. A success toast confirms the update.
+
+## Examples
+
+| Goal | Entry List |
+| --- | --- |
+| Prefer people over styles | `character, portraits, style(anime\|toon)` |
+| Group sci-fi variants | `sci-fi(scifi\|science_fiction), cyberpunk(cyber\|punk)` |
+| Alias shorthand tags | `realistic(real\|realisim), photorealistic(photo_real)` |
+
+## Tips
+
+- Keep canonical names short and meaningful—they become folder names.
+- Place the most important categories first; the first match wins.
+- Avoid duplicate canonical names within the same list; only the first instance is used.
+
+## Troubleshooting
+
+- **Unexpected folder name?** Check that the canonical name you want is placed before other matches.
+- **Alias not working?** Ensure the alias is inside parentheses and separated with `|`, e.g. `character(char|chars)`.
+- **Validation error?** Look for missing parentheses or stray commas. Each entry must follow the `canonical(alias|alias)` pattern or just `canonical`.
+
+With these basics you can quickly adapt Priority Tags to match your library’s organization style.

+2. **Sub Type** (`sub_type`): 业务层面的细分类型 - `lora`/`locon`/`dora`, `checkpoint`/`diffusion_model`, `embedding`
+
+重构目标是统一使用 `sub_type` 表示细分类型，保留 `model_type` 作为向后兼容的别名。

+#### 5.1 移除 `model_type` 字段的向后兼容代码 ✅
+- 从 `ModelScanner._build_cache_entry()` 中移除了 `model_type` 的设置
+- 现在只设置 `sub_type` 字段
+
+#### 5.2 移除 CheckpointScanner 的 model_type 兼容处理 ✅
+- `adjust_metadata()` 现在只处理 `sub_type`
+- `adjust_cached_entry()` 现在只设置 `sub_type`
+
+#### 5.3 移除 model_query 中的向后兼容别名 ✅
+- 移除了 `resolve_civitai_model_type = resolve_sub_type`
+- 移除了 `normalize_civitai_model_type = normalize_sub_type`
+
+#### 5.4 前端清理 ✅
+- `FilterManager.js` 已经在使用 `MODEL_SUBTYPE_DISPLAY_NAMES` (通过别名 `MODEL_TYPE_DISPLAY_NAMES`)
+- API list endpoint 现在只返回 `sub_type`，不再返回 `model_type`
+- `ModelCard.js` 现在设置 `card.dataset.sub_type` (所有模型类型通用)
+- `CheckpointContextMenu.js` 现在读取 `card.dataset.sub_type`
+- `MoveManager.js` 现在处理 `cache_entry.sub_type`
+- `RecipeModal.js` 现在读取 `checkpoint.sub_type`
+
+---
+
+## 数据库迁移评估
+
+### 当前状态
+- `persistent_model_cache.py` 使用 `civitai_model_type` 列存储 CivitAI 原始类型
+- 缓存 entry 中的 `sub_type` 在运行期动态计算
+- 数据库 schema **无需立即修改**
+
+### 未来可选优化
+```sql
+-- 可选：在 models 表中添加 sub_type 列（与 civitai_model_type 保持一致但语义更清晰）
+ALTER TABLE models ADD COLUMN sub_type TEXT;
+
+-- 数据迁移
+UPDATE models SET sub_type = civitai_model_type WHERE sub_type IS NULL;
+```
+
+**建议**: 如果决定添加 `sub_type` 列，应与 Phase 5 一起进行。
+

+| ~~数据库 schema 变更~~ | ~~中~~ | ~~暂缓 schema 变更，仅运行时计算~~ ✅ 无需变更 |
+| ~~前端过滤失效~~ | ~~中~~ | ~~全面的集成测试覆盖~~ ✅ 测试通过 |
+| CivitAI API 变化 | 低 | 保持多源解析策略 |
+
+---
+
+## 时间线
+
+- **v1.x**: Phase 1-4 已完成，保持向后兼容
+- **v2.0 (当前)**: ✅ Phase 5 已完成 - `model_type` 兼容代码已移除
+  - API list endpoint 只返回 `sub_type`
+  - Cache entry 只保留 `sub_type`
+  - 移除了 `resolve_civitai_model_type` 和 `normalize_civitai_model_type` 别名
+
+---
+
+## 备注
+
+- 重构期间发现 `civitai_model_type` 数据库列命名尚可，但语义上应理解为存储 CivitAI API 返回的原始类型值
+- Checkpoint 的 `diffusion_model` sub_type 不能通过 CivitAI API 获取，必须通过文件路径（model root）判断
+- LoRA 的 sub_type（lora/locon/dora）直接来自 CivitAI API 的 `version_info.model.type`

+
+### Notes
+- Over-mocking fix in `test_download_manager.py` deferred to Phase 2 as it requires significant refactoring
+- Error path tests focus on unit-level testing of downloader components rather than complex integration scenarios
+
+---
+
+## Phase 1: Critical Fixes (P0) - Week 1-2
+
+### 1.1 Fix Over-Mocking Issues
+
+**Problem:** Tests mock the methods they purport to test, hiding real bugs.
+
+**Affected Files:**
+- `tests/services/test_download_manager.py` - Mocks `_execute_download`
+- `tests/utils/test_example_images_download_manager_unit.py` - Mocks callbacks
+- `tests/routes/test_base_model_routes_smoke.py` - Uses fake service stubs
+
+**Actions:**
+1. Refactor `test_download_manager.py` to test actual download logic
+2. Replace method-level mocks with dependency injection
+3. Add integration tests that verify real behavior
+
+**Example Fix:**
+```python
+# BEFORE (Bad - mocks method under test)
+async def fake_execute_download(self, **kwargs):
+    return {"success": True}
+monkeypatch.setattr(DownloadManager, "_execute_download", fake_execute_download)
+
+# AFTER (Good - tests actual logic with injected dependencies)
+async def test_download_executes_with_real_logic(
+    tmp_path, mock_downloader, mock_websocket
+):
+    manager = DownloadManager(
+        downloader=mock_downloader,
+        ws_manager=mock_websocket
+    )
+    result = await manager._execute_download(urls=["http://test.com/file.safetensors"])
+    assert result.success is True
+    assert mock_downloader.download_calls == 1
+```
+
+### 1.2 Add Missing Error Path Tests
+
+**Problem:** Error handling code is not tested, leading to production failures.
+
+**Required Tests:**
+
+| Error Type | Module | Priority |
+|------------|--------|----------|
+| Network timeout | `downloader.py` | P0 |
+| Disk full | `download_manager.py` | P0 |
+| Permission denied | `example_images_download_manager.py` | P0 |
+| Session refresh failure | `downloader.py` | P1 |
+| Partial file cleanup | `download_manager.py` | P1 |
+
+**Implementation:**
+```python
+@pytest.mark.asyncio
+async def test_download_handles_network_timeout():
+    """Verify download retries on timeout and eventually fails gracefully."""
+    # Arrange
+    downloader = Downloader()
+    mock_session = AsyncMock()
+    mock_session.get.side_effect = asyncio.TimeoutError()
+    
+    # Act
+    success, message = await downloader.download_file(
+        url="http://test.com/file.safetensors",
+        target_path=tmp_path / "test.safetensors",
+        session=mock_session
+    )
+    
+    # Assert
+    assert success is False
+    assert "timeout" in message.lower()
+    assert mock_session.get.call_count == MAX_RETRIES
+```
+
+### 1.3 Standardize Async Test Patterns
+
+**Problem:** Inconsistent async test patterns across codebase.
+
+**Current State:**
+- Some use `@pytest.mark.asyncio`
+- Some rely on custom `pytest_pyfunc_call` in conftest.py
+- Some use bare async functions
+
+**Solution:**
+1. Add `pytest-asyncio` to requirements-dev.txt
+2. Update `pytest.ini`:
+   ```ini
+   [pytest]
+   asyncio_mode = auto
+   asyncio_default_fixture_loop_scope = function
+   ```
+3. Remove custom `pytest_pyfunc_call` handler from conftest.py
+4. Bulk update all async tests to use `@pytest.mark.asyncio`
+
+**Migration Script:**
+```bash
+# Find all async test functions missing decorator
+rg "^async def test_" tests/ --type py -A1 | grep -B1 "@pytest.mark" | grep "async def"
+
+# Add decorator (manual review required)
+```
+
+---
+
+## Phase 2: Integration & Coverage (P1) - Week 3-4
+
+### 2.1 Add Critical Module Tests
+
+**Priority 1: `py/services/model_lifecycle_service.py`**
+```python
+# tests/services/test_model_lifecycle_service.py
+class TestModelLifecycleService:
+    async def test_create_model_registers_in_cache(self):
+        """Verify new model is registered in both cache and database."""
+        
+    async def test_delete_model_cleans_up_files_and_cache(self):
+        """Verify deletion removes files and updates all indexes."""
+        
+    async def test_update_model_metadata_propagates_changes(self):
+        """Verify metadata updates reach all subscribers."""
+```
+
+**Priority 2: `py/services/persistent_recipe_cache.py`**
+```python
+# tests/services/test_persistent_recipe_cache.py
+class TestPersistentRecipeCache:
+    def test_initialization_creates_schema(self):
+        """Verify SQLite schema is created on first use."""
+        
+    async def test_save_recipe_persists_to_sqlite(self):
+        """Verify recipe data is saved correctly."""
+        
+    async def test_concurrent_access_does_not_corrupt_database(self):
+        """Verify thread safety under concurrent writes."""
+```
+
+**Priority 3: Route Handler Tests**
+- `py/routes/handlers/preview_handlers.py`
+- `py/routes/handlers/misc_handlers.py`
+- `py/routes/handlers/model_handlers.py`
+
+### 2.2 Add End-to-End Integration Tests
+
+**Download Flow Integration Test:**
+```python
+# tests/integration/test_download_flow.py
+@pytest.mark.integration
+@pytest.mark.asyncio
+async def test_complete_download_flow(tmp_path, test_server):
+    """
+    Integration test covering:
+    1. Route receives download request
+    2. DownloadCoordinator schedules it
+    3. DownloadManager executes actual download
+    4. Downloader makes HTTP request (to test server)
+    5. Progress is broadcast via WebSocket
+    6. File is saved and cache updated
+    """
+    # Setup test server with known file
+    test_file = tmp_path / "test_model.safetensors"
+    test_file.write_bytes(b"fake model data")
+    
+    # Start download
+    async with aiohttp.ClientSession() as session:
+        response = await session.post(
+            "http://localhost:8188/api/lm/download",
+            json={"urls": [f"http://localhost:{test_server.port}/test_model.safetensors"]}
+        )
+        assert response.status == 200
+        
+    # Verify file downloaded
+    downloaded = tmp_path / "downloads" / "test_model.safetensors"

+    # Verify WebSocket progress updates
+    assert len(ws_manager.broadcasts) > 0
+    assert any(b["status"] == "completed" for b in ws_manager.broadcasts)

+
+**Recipe Flow Integration Test:**
+```python

+    """
+    Integration test covering:
+    1. Import recipe from image
+    2. Parse metadata and extract models
+    3. Save to cache and database
+    4. Retrieve and display
+    """
+```
+
+### 2.3 Strengthen Assertions
+
+**Replace loose assertions:**
+```python
+# BEFORE
+assert "mismatch" in message.lower()
+
+# AFTER
+assert message == "File size mismatch. Expected: 1000 bytes, Got: 500 bytes"
+assert not target_path.exists()
+assert not Path(str(target_path) + ".part").exists()
+assert len(downloader.retry_history) == 3
+```
+
+**Add state verification:**
+```python
+# BEFORE
+assert result is True
+
+# AFTER
+assert result is True
+assert model["status"] == "downloaded"
+assert model["file_path"].exists()
+assert cache.get_by_hash(model["sha256"]) is not None
+assert len(ws_manager.payloads) >= 2  # Started + completed
+```

+- `tests/services/test_download_manager.py` (1000+ lines) → Split into:
+  - `test_download_manager_basic.py` - Core functionality
+  - `test_download_manager_error.py` - Error handling
+  - `test_download_manager_concurrent.py` - Concurrent operations
+
+- `tests/utils/test_cache_paths.py` (529 lines) → Split into:
+  - `test_cache_paths_resolution.py`
+  - `test_cache_paths_validation.py`
+  - `test_cache_paths_migration.py`
+
+### 3.3 Refactor Complex Tests
+
+**Example: Simplify test setup in `test_example_images_download_manager_unit.py`**
+
+**Current (Complex):**
+```python
+async def test_start_download_bootstraps_progress_and_task(
+    monkeypatch: pytest.MonkeyPatch, tmp_path
+):
+    # 40+ lines of setup
+    started = asyncio.Event()
+    release = asyncio.Event()
+    
+    async def fake_download(self, ...):
+        started.set()
+        await release.wait()
+        # ... more logic ...
+```
+
+**Improved (Using fixtures):**
+```python
+async def test_start_download_bootstraps_progress_and_task(
+    download_manager_with_fake_backend, release_event
+):
+    # Setup in fixtures, test is clean
+    manager = download_manager_with_fake_backend
+    result = await manager.start_download({"model_types": ["lora"]})
+    assert result["success"] is True
+    assert manager._is_downloading is True
+```
+
+---
+
+## Phase 4: Advanced Testing (P3) - Week 7-8
+
+### 4.1 Add Property-Based Tests (Hypothesis)
+
+**Install:** `pip install hypothesis`
+
+**Example:**
+```python
+# tests/utils/test_hash_utils_hypothesis.py
+from hypothesis import given, strategies as st
+
+@given(st.text(min_size=1, max_size=100))
+def test_hash_normalization_idempotent(name):
+    """Hash normalization should be idempotent."""
+    normalized = normalize_hash(name)
+    assert normalize_hash(normalized) == normalized
+
+@given(st.lists(st.dictionaries(st.text(), st.text()), min_size=0, max_size=1000))
+def test_model_cache_handles_any_model_list(models):
+    """Cache should handle any list of models without crashing."""
+    cache = ModelCache()
+    cache.raw_data = models
+    # Should not raise
+    list(cache.iter_models())
+```
+
+### 4.2 Add Snapshot Tests (Syrupy)
+
+**Install:** `pip install syrupy`
+
+**Example:**
+```python
+# tests/routes/test_api_snapshots.py
+import pytest
+
+@pytest.mark.asyncio
+async def test_lora_list_response_format(snapshot, client):
+    """Verify API response format matches snapshot."""
+    response = await client.get("/api/lm/loras")
+    data = await response.json()
+    assert data == snapshot  # Syrupy handles this
+```
+
+### 4.3 Add Performance Benchmarks
+
+**Install:** `pip install pytest-benchmark`
+
+**Example:**
+```python
+# tests/performance/test_cache_performance.py
+import pytest
+
+def test_cache_lookup_performance(benchmark):
+    """Benchmark cache lookup with 10,000 models."""
+    cache = create_cache_with_n_models(10000)
+    
+    result = benchmark(lambda: cache.get_by_hash("abc123"))
+    # Benchmark automatically collects timing stats
+```
+

+# Backend Test Coverage Notes
+
+## Pytest Execution
+- Command: `python -m pytest`
+- Result: All 283 collected tests passed in the current environment.
+- Coverage tooling (``pytest-cov``/``coverage``) is unavailable in the offline sandbox, so line-level metrics could not be generated. The earlier attempt to install ``pytest-cov`` failed because the package index cannot be reached from the container.
+
+## High-Priority Gaps to Address
+
+### 1. Standalone server bootstrapping
+* **Source:** [`standalone.py`](../../standalone.py)
+* **Why it matters:** The standalone entry point wires together the aiohttp application, static asset routes, model-route registration, and configuration validation. None of these behaviours are covered by automated tests, leaving regressions in bootstrapping logic undetected.
+* **Suggested coverage:** Add integration-style tests that instantiate `StandaloneServer`/`StandaloneLoraManager` with temporary settings and assert that routes (HTTP + websocket) are registered, configuration warnings fire for missing paths, and the mock ComfyUI shims behave as expected.
+
+### 2. Model service registration factory
+* **Source:** [`py/services/model_service_factory.py`](../../py/services/model_service_factory.py)
+* **Why it matters:** The factory coordinates which model services and routes the API exposes, including error handling when unknown model types are requested. No current tests verify registration, memoization of route instances, or the logging path on failures.
+* **Suggested coverage:** Unit tests that exercise `register_model_type`, `get_route_instance`, error branches in `get_service_class`/`get_route_class`, and `setup_all_routes` when a route setup raises. Use lightweight fakes to confirm the logger is called and state is cleared via `clear_registrations`.
+
+### 3. Server-side i18n helper
+* **Source:** [`py/services/server_i18n.py`](../../py/services/server_i18n.py)
+* **Why it matters:** Template rendering relies on the `ServerI18nManager` to load locale JSON, perform key lookups, and format parameters. The fallback logic (dot-notation lookup, English fallbacks, placeholder substitution) is untested, so malformed locale files or regressions in placeholder handling would slip through.
+* **Suggested coverage:** Tests that load fixture locale dictionaries, assert `set_locale` fallbacks, verify nested key resolution and placeholder substitution, and ensure missing keys return the original identifier.
+
+## Next Steps
+Prioritize creating focused unit tests around these modules, then re-run pytest once coverage tooling is available to confirm the new tests close the identified gaps.

+# Settings Modal UI/UX Optimization
+
+## Overview
+当前Settings Modal采用单列表长页面设计，随着设置项不断增加，已难以高效浏览和定位。本方案采用 **macOS Settings 模式**（左侧导航 + 右侧单Section独占显示），在保持原有设计语言的前提下，重构信息架构，大幅提升用户体验。
+
+## Goals
+1. **提升浏览效率**：用户能够快速定位和修改设置
+2. **保持设计一致性**：延续现有的颜色、间距、动画系统
+3. **简化交互模型**：移除冗余元素（SETTINGS label、折叠功能）
+4. **清晰的视觉层次**：Section级导航，右侧独占显示
+5. **向后兼容**：不影响现有功能逻辑
+
+## Design Principles
+- **macOS Settings模式**：点击左侧导航，右侧仅显示该Section内容
+- **贴近原有设计语言**：使用现有CSS变量和样式模式
+- **最小化风格改动**：在提升UX的同时保持视觉风格稳定
+- **简化优于复杂**：移除不必要的折叠/展开交互
+
+---
+
+## New Design Architecture
+
+### Layout Structure

+
+### Key Design Decisions
+
+#### 1. 移除冗余元素
+- ❌ 删除 sidebar 中的 "SETTINGS" label
+- ❌ **取消折叠/展开功能**（增加交互成本，无实际收益）
+- ❌ 不再在左侧导航显示具体设置项（减少认知负荷）
+
+#### 2. 导航简化
+- 左侧仅显示 **4个Section**（General / Interface / Download / Advanced）
+- 当前选中项用 accent 色 background highlight
+- 无需滚动监听，点击即切换
+
+#### 3. 右侧单Section独占
+- 点击左侧导航，右侧仅显示该Section的所有设置项
+- Section标题作为页面标题（大号字体 + accent色下划线）
+- 所有设置项平铺展示，无需折叠
+
+#### 4. 视觉层次
+```
+Section Header (20px, bold, accent underline)
+├── Setting Group (card container, subtle border)
+│   ├── Setting Label (14px, semibold)
+│   ├── Setting Description (12px, muted color)
+│   └── Setting Control (input/select/toggle)
+```
+
+---
+
+## Optimization Phases
+
+### Phase 0: macOS Settings模式重构 (P0)
+**Status**: Ready for Development
+**Priority**: High
+
+#### Goals
+- 重构为两栏布局（左侧导航 + 右侧内容）
+- 实现Section级导航切换
+- 优化视觉层次和间距
+- 移除冗余元素

+
+## Notes
+
+### Design Decisions
+- 采用macOS Settings模式而非长页面滚动模式
+- 左侧仅显示4个Section，不显示具体设置项
+- 移除折叠/展开功能，简化交互
+- Section标题使用accent色下划线强调
+
+### Technical Notes
+- 优先使用现有CSS变量
+- 保持向后兼容，不破坏现有设置存储逻辑
+- 移动端响应式：小屏幕单栏堆叠
+
+### Blockers
+None
+
