+# Repository Guidelines
+
+## Project Structure & Module Organization
+ComfyUI LoRA Manager pairs a Python backend with browser-side widgets. Backend modules live in <code>py/</code> with HTTP entry points in <code>py/routes/</code>, feature logic in <code>py/services/</code>, shared helpers in <code>py/utils/</code>, and custom nodes in <code>py/nodes/</code>. UI scripts extend ComfyUI from <code>web/comfyui/</code>, while deploy-ready assets remain in <code>static/</code> and <code>templates/</code>. Localization files live in <code>locales/</code>, example workflows in <code>example_workflows/</code>, and interim tests such as <code>test_i18n.py</code> sit beside their source until a dedicated <code>tests/</code> tree lands.
+
+## Build, Test, and Development Commands
+- <code>pip install -r requirements.txt</code> installs backend dependencies.
+- <code>python standalone.py --port 8188</code> launches the standalone server for iterative development.
+- <code>python -m pytest test_i18n.py</code> runs the current regression suite; target new files explicitly, e.g. <code>python -m pytest tests/test_recipes.py</code>.
+- <code>python scripts/sync_translation_keys.py</code> synchronizes locale keys after UI string updates.
+
+## Coding Style & Naming Conventions
+Follow PEP 8 with four-space indentation and descriptive snake_case file and function names such as <code>settings_manager.py</code>. Classes stay PascalCase, constants in UPPER_SNAKE_CASE, and loggers retrieved via <code>logging.getLogger(__name__)</code>. Prefer explicit type hints and docstrings on public APIs. JavaScript under <code>web/comfyui/</code> uses ES modules with camelCase helpers and the <code>_widget.js</code> suffix for UI components.
+
+## Testing Guidelines
+Pytest powers backend tests. Name modules <code>test_<feature>.py</code> and keep them near the code or in a future <code>tests/</code> package. Mock ComfyUI dependencies through helpers in <code>standalone.py</code>, keep filesystem fixtures deterministic, and ensure translations are covered. Run <code>python -m pytest</code> before submitting changes.
+
+## Commit & Pull Request Guidelines
+Commits follow the conventional format, e.g. <code>feat(settings): add default model path</code>, and should stay focused on a single concern. Pull requests must outline the problem, summarize the solution, list manual verification steps (server run, targeted pytest), and link related issues. Include screenshots or GIFs for UI or locale updates and call out migration steps such as <code>settings.json</code> adjustments.
+
+## Configuration & Localization Tips
+Copy <code>settings.json.example</code> to <code>settings.json</code> and adapt model directories before running the standalone server. Store reference assets in <code>civitai/</code> or <code>docs/</code> to keep runtime directories deploy-ready. Whenever UI text changes, update every <code>locales/&lt;lang&gt;.json</code> file and rerun the translation sync script so ComfyUI surfaces localized strings.

-  - Marquee selection events (mousedown, mousemove, mouseup, contextmenu)
-  - State synchronization with EventManager
-- **Benefits**:
-  - Centralized priority handling
-  - Conditional execution based on modal state
-  - Better coordination with other components
-
-### 3. UIHelpers Integration
-- **Location**: `static/js/utils/uiHelpers.js`
-- **Migrated Events**:
-  - Mouse position tracking for node selector positioning
-  - Node selector click events (outside clicks and selection)
-  - State management for node selector
-- **Benefits**:
-  - Reduced direct DOM listeners
-  - Coordinated state tracking
-  - Better cleanup
-
-### 4. ModelCard Integration
-- **Location**: `static/js/components/shared/ModelCard.js`
-- **Migrated Events**:
-  - Model card click delegation
-  - Action button handling (star, globe, copy, etc.)
-  - Better return value handling for event propagation
-- **Benefits**:
-  - Single event listener for all model cards
-  - Priority-based execution
-  - Better event flow control
-
-### 5. Documentation and Initialization
-- **EventManagerDocs.md**: Comprehensive documentation
-- **eventManagementInit.js**: Initialization and global handlers
-- **Features**:
-  - Global escape key handling
-  - Modal state synchronization
-  - Error handling
-  - Analytics integration points
-  - Cleanup on page unload
-
-## Application States Tracked
-
-1. **bulkMode**: When bulk selection mode is active
-2. **marqueeActive**: When marquee selection is in progress  
-3. **modalOpen**: When any modal dialog is open
-4. **nodeSelectorActive**: When node selector popup is visible
-
-## Priority Levels Used
-
-- **250+**: Critical system events (escape keys)
-- **200+**: High priority system events (modal close)
-- **100-199**: Application-level shortcuts (bulk operations)
-- **80-99**: UI interactions (marquee selection)
-- **60-79**: Component interactions (model cards)
-- **10-49**: Tracking and monitoring
-- **1-9**: Analytics and low-priority tasks
-
-## Event Flow Examples
-
-### Bulk Mode Toggle (B key)
-1. **Priority 100**: BulkManager keyboard handler catches 'b' key
-2. Toggles bulk mode state
-3. Updates EventManager state
-4. Updates UI accordingly
-5. Stops propagation (returns true)
-
-### Marquee Selection
-1. **Priority 80**: BulkManager mousedown handler (only in .models-container, excluding cards/buttons)
-2. Starts marquee selection
-3. **Priority 90**: BulkManager mousemove handler (only when marquee active)
-4. Updates selection rectangle
-5. **Priority 90**: BulkManager mouseup handler ends selection
-
-### Model Card Click
-1. **Priority 60**: ModelCard delegation handler checks for specific elements
-2. If action button: handles action and stops propagation
-3. If general card click: continues to other handlers
-4. Bulk selection may also handle the event if in bulk mode
-
-## Remaining Event Listeners (Not Yet Migrated)
-
-### High Priority for Migration
-1. **SearchManager keyboard events** - Global search shortcuts
-2. **ModalManager escape handling** - Already integrated with initialization
-3. **Scroll-based events** - Back to top, virtual scrolling
-4. **Resize events** - Panel positioning, responsive layouts
-
-### Medium Priority
-1. **Form input events** - Tag inputs, settings forms
-2. **Component-specific events** - Recipe modal, showcase view
-3. **Sidebar events** - Resize handling, toggle events
-
-### Low Priority (Can Remain As-Is)
-1. **VirtualScroller events** - Performance-critical, specialized
-2. **Component lifecycle events** - Modal open/close callbacks
-3. **One-time setup events** - Theme initialization, etc.
-
-## Benefits Achieved
-
-### Performance Improvements
-- **Reduced DOM listeners**: From ~15+ individual listeners to ~5 coordinated handlers
-- **Conditional execution**: Handlers only run when conditions are met
-- **Priority ordering**: Important events handled first
-- **Better memory management**: Automatic cleanup prevents leaks
-
-### Coordination Improvements
-- **State synchronization**: All components aware of app state
-- **Event flow control**: Proper propagation stopping
-- **Conflict resolution**: Priority system prevents conflicts
-- **Debugging**: Centralized event handling for easier debugging
-
-### Code Quality Improvements
-- **Consistent patterns**: All event handling follows same patterns
-- **Better separation of concerns**: Event logic separated from business logic
-- **Error handling**: Centralized error catching and reporting
-- **Documentation**: Clear patterns for future development
-
-## Next Steps (Recommendations)
-
-### 1. Migrate Search Events
-```javascript
-// In SearchManager.js
-eventManager.addHandler('keydown', 'search-shortcuts', (e) => {
-    if ((e.ctrlKey || e.metaKey) && e.key === 'f') {
-        this.focusSearchInput();
-        return true;
-    }
-}, { priority: 120 });
-```
-
-### 2. Integrate Resize Events
-```javascript
-// Create ResizeManager
-eventManager.addHandler('resize', 'layout-resize', debounce((e) => {
-    this.updateLayoutDimensions();
-}, 250), { priority: 50 });
-```
-
-### 3. Add Debug Mode
-```javascript
-// In EventManager.js
-if (window.DEBUG_EVENTS) {
-    console.log(`Event ${eventType} handled by ${source} (priority: ${priority})`);
-}
-```
-
-### 4. Create Event Analytics
-```javascript
-// Track event patterns for optimization
-eventManager.addHandler('*', 'analytics', (e) => {
-    this.trackEventUsage(e.type, performance.now());
-}, { priority: 1 });
-```
-
-## Testing Recommendations
-
-1. **Verify bulk mode interactions** work correctly
-2. **Test marquee selection** in various scenarios
-3. **Check modal state synchronization** 
-4. **Verify node selector** positioning and cleanup
-5. **Test keyboard shortcuts** don't conflict
-6. **Verify proper cleanup** when components are destroyed
-
-The centralized event management system provides a solid foundation for coordinated, efficient event handling across the application while maintaining good performance and code organization.

-# Centralized Event Management System
-
-This document describes the centralized event management system that coordinates event handling across the ComfyUI LoRA Manager application.
-
-## Overview
-
-The `EventManager` class provides a centralized way to handle DOM events with priority-based execution, conditional execution based on application state, and proper cleanup mechanisms.
-
-## Features
-
-- **Priority-based execution**: Handlers with higher priority run first
-- **Conditional execution**: Handlers can be executed based on application state
-- **Element filtering**: Handlers can target specific elements or exclude others
-- **Automatic cleanup**: Cleanup functions are called when handlers are removed
-- **State tracking**: Tracks application states like bulk mode, modal open, etc.
-
-## Basic Usage
-
-### Importing
-
-```javascript
-import { eventManager } from './EventManager.js';
-```
-
-### Adding Event Handlers
-
-```javascript
-eventManager.addHandler('click', 'myComponent', (event) => {
-    console.log('Button clicked!');
-    return true; // Stop propagation to other handlers
-}, {
-    priority: 100,
-    targetSelector: '.my-button',
-    skipWhenModalOpen: true
-});
-```
-
-### Removing Event Handlers
-
-```javascript
-// Remove specific handler
-eventManager.removeHandler('click', 'myComponent');
-
-// Remove all handlers for a component
-eventManager.removeAllHandlersForSource('myComponent');
-```
-
-### Updating Application State
-
-```javascript
-// Set state
-eventManager.setState('bulkMode', true);
-eventManager.setState('modalOpen', true);
-
-// Get state
-const isBulkMode = eventManager.getState('bulkMode');
-```
-
-## Available States
-
-- `bulkMode`: Whether bulk selection mode is active
-- `marqueeActive`: Whether marquee selection is in progress
-- `modalOpen`: Whether any modal is currently open
-- `nodeSelectorActive`: Whether the node selector popup is active
-
-## Handler Options
-
-### Priority
-Higher numbers = higher priority. Handlers run in descending priority order.
-
-```javascript
-{
-    priority: 100 // High priority
-}
-```
-
-### Conditional Execution
-
-```javascript
-{
-    onlyInBulkMode: true,               // Only run when bulk mode is active
-    onlyWhenMarqueeActive: true,        // Only run when marquee selection is active
-    skipWhenModalOpen: true,            // Skip when any modal is open
-    skipWhenNodeSelectorActive: true,   // Skip when node selector is active
-    onlyWhenNodeSelectorActive: true    // Only run when node selector is active
-}
-```
-
-### Element Filtering
-
-```javascript
-{
-    targetSelector: '.model-card',      // Only handle events on matching elements
-    excludeSelector: 'button, input',  // Exclude events from these elements
-    button: 0                          // Only handle specific mouse button (0=left, 1=middle, 2=right)
-}
-```
-
-### Cleanup Functions
-
-```javascript
-{
-    cleanup: () => {
-        // Custom cleanup logic
-        console.log('Handler cleaned up');
-    }
-}
-```
-
-## Integration Examples
-
-### BulkManager Integration
-
-```javascript
-class BulkManager {
-    registerEventHandlers() {
-        // High priority keyboard shortcuts
-        eventManager.addHandler('keydown', 'bulkManager-keyboard', (e) => {
-            return this.handleGlobalKeyboard(e);
-        }, {
-            priority: 100,
-            skipWhenModalOpen: true
-        });
-
-        // Marquee selection
-        eventManager.addHandler('mousedown', 'bulkManager-marquee-start', (e) => {
-            return this.handleMarqueeStart(e);
-        }, {
-            priority: 80,
-            skipWhenModalOpen: true,
-            targetSelector: '.models-container',
-            excludeSelector: '.model-card, button, input',
-            button: 0
-        });
-    }
-    
-    cleanup() {
-        eventManager.removeAllHandlersForSource('bulkManager-keyboard');
-        eventManager.removeAllHandlersForSource('bulkManager-marquee-start');
-    }
-}
-```
-
-### Modal Integration
-
-```javascript
-class ModalManager {
-    showModal(modalId) {
-        // Update state when modal opens
-        eventManager.setState('modalOpen', true);
-        this.displayModal(modalId);
-    }
-    
-    closeModal(modalId) {
-        // Update state when modal closes
-        eventManager.setState('modalOpen', false);
-        this.hideModal(modalId);
-    }
-}
-```
-
-### Component Event Delegation
-
-```javascript
-export function setupComponentEvents() {
-    eventManager.addHandler('click', 'myComponent-actions', (event) => {
-        const button = event.target.closest('.action-button');
-        if (!button) return false;
-        
-        this.handleAction(button.dataset.action);
-        return true; // Stop propagation
-    }, {
-        priority: 60,
-        targetSelector: '.component-container'
-    });
-}
-```
-
-## Best Practices
-
-### 1. Use Descriptive Source Names
-Use the format `componentName-purposeDescription`:
-```javascript
-// Good
-'bulkManager-marqueeSelection'
-'nodeSelector-clickOutside'
-'modelCard-delegation'
-
-// Avoid
-'bulk'
-'click'
-'handler1'
-```
-
-### 2. Set Appropriate Priorities
-- 200+: Critical system events (escape keys, critical modals)
-- 100-199: High priority application events (keyboard shortcuts)
-- 50-99: Normal UI interactions (buttons, cards)
-- 1-49: Low priority events (tracking, analytics)
-
-### 3. Use Conditional Execution
-Instead of checking state inside handlers, use options:
-```javascript
-// Good
-eventManager.addHandler('click', 'bulk-action', handler, {
-    onlyInBulkMode: true
-});
-
-// Avoid
-eventManager.addHandler('click', 'bulk-action', (e) => {
-    if (!state.bulkMode) return;
-    // handler logic
-});
-```
-
-### 4. Clean Up Properly
-Always clean up handlers when components are destroyed:
-```javascript
-class MyComponent {
-    constructor() {
-        this.registerEvents();
-    }
-    
-    destroy() {
-        eventManager.removeAllHandlersForSource('myComponent');
-    }
-}
-```
-
-### 5. Return Values Matter
-- Return `true` to stop event propagation to other handlers
-- Return `false` or `undefined` to continue with other handlers
-
-## Migration Guide
-
-### From Direct Event Listeners
-
-**Before:**
-```javascript
-document.addEventListener('click', (e) => {
-    if (e.target.closest('.my-button')) {
-        this.handleClick(e);
-    }
-});
-```
-
-**After:**
-```javascript
-eventManager.addHandler('click', 'myComponent-button', (e) => {
-    this.handleClick(e);
-}, {
-    targetSelector: '.my-button'
-});
-```
-
-### From Event Delegation
-
-**Before:**
-```javascript
-container.addEventListener('click', (e) => {
-    const card = e.target.closest('.model-card');
-    if (!card) return;
-    
-    if (e.target.closest('.action-btn')) {
-        this.handleAction(e);
-    }
-});
-```
-
-**After:**
-```javascript
-eventManager.addHandler('click', 'container-actions', (e) => {
-    const card = e.target.closest('.model-card');
-    if (!card) return false;
-    
-    if (e.target.closest('.action-btn')) {
-        this.handleAction(e);
-        return true;
-    }
-}, {
-    targetSelector: '.container'
-});
-```
-
-## Performance Benefits
-
-1. **Reduced DOM listeners**: Single listener per event type instead of multiple
-2. **Conditional execution**: Handlers only run when conditions are met
-3. **Priority ordering**: Important handlers run first, avoiding unnecessary work
-4. **Automatic cleanup**: Prevents memory leaks from orphaned listeners
-5. **Centralized debugging**: All event handling flows through one system
-
-## Debugging
-
-Enable debug logging to trace event handling:
-```javascript
-// Add to EventManager.js for debugging
-console.log(`Handling ${eventType} event with ${handlers.length} handlers`);
-```
-
-The event manager provides a foundation for coordinated, efficient event handling across the entire application.

+
+---
+
+## Why Are All Features for Supporters Only?
+
+I love building tools for the Stable Diffusion and ComfyUI communities, and LoRA Manager is a passion project that I've poured countless hours into. When I created this companion extension, my hope was to offer its core features for free, as a thank-you to all of you.
+
+Unfortunately, I've reached a point where I need to be realistic. The level of support from the free model has been far lower than what's needed to justify the continuous development and maintenance for both projects. It was a difficult decision, but I've chosen to make the extension's features exclusive to supporters.
+
+This change is crucial for me to be able to continue dedicating my time to improving the free and open-source LoRA Manager, which I'm committed to keeping available for everyone.
+
+Your support does more than just unlock a few features—it allows me to keep innovating and ensures the core LoRA Manager project thrives. I'm incredibly grateful for your understanding and any support you can offer. ❤️
+
+(_For those who previously supported me on Ko-fi with a one-time donation, I'll be sending out license keys individually as a thank-you._)

+
+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.
+
+When switching to a specific version by clicking a version button:
+
+- Clicking the download button will open a dropdown:
+  - Download via **LoRA Manager**  
+  - Download via **Original Download** (browser download)  
+
+You can check **Remember my choice** to set your preferred default. You can change this setting anytime in the extension's settings.
+
+![Civitai Model Page](https://github.com/willmiao/ComfyUI-Lora-Manager/blob/main/wiki-images/civitai-model-page.png)
+
+### Resources on Image Pages (2025-08-05) — now shows in-library indicators for image resources. ‘Import image as recipe’ coming soon!
+
+![Civitai Image Page](https://github.com/willmiao/ComfyUI-Lora-Manager/blob/main/wiki-images/civitai-image-page.jpg)
+
+---
+
+## 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)
+- [ ] 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**
+
+**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

+    subgraph HTTP

+        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. |
+
+## Handler responsibilities & invariants
+
+`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:

+```
+
+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.

+| 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.

+# 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 adds it to filters, applies active styling, and reloads results | Tag stored under `filters.tags`; `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.

+# Frontend Automation Testing Roadmap
+
+This roadmap tracks the planned rollout of automated testing for the ComfyUI LoRA Manager frontend. Each phase builds on the infrastructure introduced in this change set and records progress so future contributors can quickly identify the next tasks.
+
+## Phase Overview
+
+| Phase | Goal | Primary Focus | Status | Notes |
+| --- | --- | --- | --- | --- |
+| Phase 0 | Establish baseline tooling | Add Node test runner, jsdom environment, and seed smoke tests | ✅ Complete | Vitest + jsdom configured, example state tests committed |
+| Phase 1 | Cover state management logic | Unit test selectors, derived data helpers, and storage utilities under `static/js/state` and `static/js/utils` | ✅ Complete | Storage helpers and state selectors now exercised via deterministic suites |
+| Phase 2 | Test AppCore orchestration | Simulate page bootstrapping, infinite scroll hooks, and manager registration using JSDOM DOM fixtures | ✅ Complete | AppCore initialization + page feature suites now validate manager wiring, infinite scroll hooks, and onboarding gating |
+| Phase 3 | Validate page-specific managers | Add focused suites for `loras`, `checkpoints`, `embeddings`, and `recipes` managers covering filtering, sorting, and bulk actions | ✅ Complete | LoRA/checkpoint suites expanded; embeddings + recipes managers now covered with initialization, filtering, and duplicate workflows |
+| Phase 4 | Interaction-level regression tests | Exercise template fragments, modals, and menus to ensure UI wiring remains intact | ✅ Complete | Vitest DOM suites cover NSFW selector, recipe modal editing, and global context menus |
+| Phase 5 | Continuous integration & coverage | Integrate frontend tests into CI workflow and track coverage metrics | ✅ Complete | CI workflow runs Vitest and aggregates V8 coverage into `coverage/frontend` via a dedicated script |
+
+## Next Steps Checklist
+
+- [x] Expand unit tests for `storageHelpers` covering migrations and namespace behavior.
+- [x] Document DOM fixture strategy for reproducing template structures in tests.
+- [x] Prototype AppCore initialization test that verifies manager bootstrapping with stubbed dependencies.
+- [x] Add AppCore page feature suite exercising context menu creation and infinite scroll registration via DOM fixtures.
+- [x] Extend AppCore orchestration tests to cover manager wiring, bulk menu setup, and onboarding gating scenarios.
+- [x] Add interaction regression suites for context menus and recipe modals to complete Phase 4.
+- [x] Evaluate integrating coverage reporting once test surface grows (> 20 specs).
+- [x] Create shared fixtures for the loras and checkpoints pages once dedicated manager suites are added.
+- [x] Draft focused test matrix for loras/checkpoints manager filtering and sorting paths ahead of Phase 3.
+- [x] Implement LoRAs manager filtering/sorting specs for scenarios F-01–F-05 & F-09; queue remaining edge cases after duplicate/bulk flows stabilize.
+- [x] Implement checkpoints manager filtering/sorting specs for scenarios F-01–F-05 & F-09; cover remaining paths alongside bulk action work.
+- [x] Implement checkpoints page manager smoke tests covering initialization and duplicate badge wiring.
+- [x] Outline focused checkpoints scenarios (filtering, sorting, duplicate badge toggles) to feed into the shared test matrix.
+- [ ] Add duplicate badge regression coverage for zero/pending states after API refreshes.
+
+Maintaining this roadmap alongside code changes will make it easier to append new automated test tasks and update their progress.

-            "text": "A cinematic, oil painting masterpiece captures the essence of impressionistic surrealism, inspired by Claude Monet. A mysterious woman in a flowing crimson dress stands at the edge of a tranquil lake, where lily pads shimmer under an ethereal, golden twilight. The water’s surface reflects a dreamlike sky, its swirling hues of violet and sapphire melting together like liquid light. The thick, expressive brushstrokes lend depth to the scene, evoking a sense of nostalgia and quiet longing, as if the world itself is caught between reality and a fleeting dream.  \nA mesmerizing oil painting masterpiece inspired by Salvador Dalí, blending surrealism with post-impressionist texture. A lone violinist plays atop a melting clock tower, his form distorted by the passage of time. The sky is a cascade of swirling, liquid oranges and deep blues, where floating staircases spiral endlessly into the horizon. The impasto technique gives depth and movement to the surreal elements, making time itself feel fluid, as if the world is dissolving into a dream.  \nA stunning impressionistic oil painting evokes the spirit of Edvard Munch, capturing a solitary figure standing on a rain-soaked street, illuminated by the glow of flickering gas lamps. The swirling, chaotic strokes of deep blues and fiery reds reflect the turbulence of emotion, while the blurred reflections in the wet cobblestone suggest a merging of past and present. The faceless figure, draped in a dark overcoat, seems lost in thought, embodying the ephemeral nature of memory and time.  \nA breathtaking oil painting masterpiece, inspired by Gustav Klimt, presents a celestial ballroom where faceless dancers swirl in an eternal waltz beneath a gilded, star-speckled sky. Their golden garments shimmer with intricate patterns, blending into the opulent mosaic floor that seems to stretch into infinity. The dreamlike composition, rich in warm amber and deep sapphire hues, captures an otherworldly elegance, as if the dancers are suspended in a moment that transcends time.  \nA visionary oil painting inspired by Marc Chagall depicts a dreamlike cityscape where gravity ceases to exist. A couple floats above a crimson-tinted town, their forms dissolving into the swirling strokes of a vast, cerulean sky. The buildings below twist and bend in rhythmic motion, their windows glowing like tiny stars. The thick, textured brushwork conveys a sense of weightlessness and wonder, as if love itself has defied the laws of the universe.  \nAn impressionistic oil painting in the style of J.M.W. Turner, depicting a ghostly ship sailing through a sea of swirling golden mist. The waves crash and dissolve into abstract, fiery strokes of orange and deep indigo, blurring the line between ocean and sky. The ship appears almost ethereal, as if drifting between worlds, lost in the ever-changing tides of memory and myth. The dynamic brushstrokes capture the relentless power of nature and the fleeting essence of time.  \nA captivating oil painting masterpiece, infused with surrealist impressionism, portrays a grand library where books float midair, their pages unraveling into ribbons of light. The towering shelves twist into the heavens, vanishing into an infinite, starry void. A lone scholar, illuminated by the glow of a suspended lantern, reaches for a book that seems to pulse with life. The scene pulses with mystery, where the impasto textures bring depth to the interplay between knowledge and dreams.  \nA luminous impressionistic oil painting captures the melancholic beauty of an abandoned carnival, its faded carousel horses frozen mid-gallop beneath a sky of swirling lavender and gold. The wind carries fragments of forgotten laughter through the empty fairground, where scattered ticket stubs and crumbling banners whisper tales of joy long past. The thick, textured brushstrokes blend nostalgia with an eerie dreamlike quality, as if the carnival exists only in the echoes of memory.  \nA surreal oil painting in the spirit of René Magritte, featuring a towering lighthouse that emits not light, but cascading waterfalls from its peak. The swirling sky, painted in deep midnight blues, is punctuated by glowing, crescent moons that defy gravity. A lone figure stands at the water’s edge, gazing up in quiet contemplation, as if caught between wonder and the unknown. The painting’s rich textures and luminous colors create an enigmatic, dreamlike landscape.  \nA striking impressionistic oil painting, reminiscent of Van Gogh, portrays a lone traveler on a winding cobblestone path, their silhouette bathed in the golden glow of lantern-lit cherry blossoms. The petals swirl through the night air like glowing embers, blending with the deep, rhythmic strokes of a star-filled indigo sky. The scene captures a feeling of wistful solitude, as if the traveler is walking not only through the city, but through the fleeting nature of time itself."
