feat: lazy hash calculation for checkpoints

Checkpoints are typically large (10GB+). This change delays SHA256
hash calculation until metadata fetch from Civitai is requested,
significantly improving initial scan performance.

- Add hash_status field to BaseModelMetadata
- CheckpointScanner skips hash during initial scan
- On-demand hash calculation during Civitai fetch
- Background bulk hash calculation support

-- Use `logging.getLogger(__name__)` for module-level loggers
-- Define custom exceptions in `py/services/errors.py`
-- Use `asyncio.Lock` for thread-safe singleton patterns
-- Raise specific exceptions with descriptive messages
-- Log errors at appropriate levels (DEBUG, INFO, WARNING, ERROR, CRITICAL)

+- `async def` for I/O, `@pytest.mark.asyncio` for async tests
+- Singleton with `asyncio.Lock`: see `ModelScanner.get_instance()`

 ## Architecture Patterns
 
 ### Service Layer
 
-- Use `ServiceRegistry` singleton for dependency injection
-- Services follow singleton pattern via `get_instance()` class method
+- `ServiceRegistry` singleton for DI, services use `get_instance()` classmethod
 - Separate scanners (discovery) from services (business logic)
-- Handlers in `py/routes/handlers/` implement route logic
+- Handlers in `py/routes/handlers/` are pure functions with deps as params
 
-### Model Types
+### Model Types & Routes
 
-- BaseModelService is abstract base for LoRA, Checkpoint, Embedding services
-- ModelScanner provides file discovery and hash-based deduplication
-- Persistent cache in SQLite via `PersistentModelCache`
-- Metadata sync from CivitAI/CivArchive via `MetadataSyncService`
-
-### Routes & Handlers
-
-- Route registrars organize endpoints by domain: `ModelRouteRegistrar`, etc.
-- Handlers are pure functions taking dependencies as parameters
-- Use `WebSocketManager` for real-time progress updates
-- Return `aiohttp.web.json_response` or `web.Response`
+- `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 metadata in `py/recipes/base.py`
-- Enrichment adds model metadata: `RecipeEnrichmentService`
-- Parsers for different formats in `py/recipes/parsers/`
+- 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 (uses folder_paths) vs standalone (reads settings.json)
+- 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"`
-- Settings auto-saved in user directory or portable mode
-- WebSocket broadcasts for real-time updates (downloads, scans)
-- Symlink handling requires normalized paths
-- API endpoints follow `/loras/*`, `/checkpoints/*`, `/embeddings/*` patterns
 - Run `python scripts/sync_translation_keys.py` after UI string updates
+- Symlinks require normalized paths
 
 ## Frontend UI Architecture
 
-This project has two distinct UI systems:
-
-### 1. Standalone Lora Manager Web UI
+### 1. Standalone Web UI
 - Location: `./static/` and `./templates/`
-- Purpose: Full-featured web application for managing LoRA models
-- Tech stack: Vanilla JS + CSS, served by the standalone server
-- Development: Uses npm for frontend testing (`npm test`, `npm run test:watch`, etc.)
+- Tech: Vanilla JS + CSS, served by standalone server
+- Tests via npm in root directory
 
 ### 2. ComfyUI Custom Node Widgets
-- Location: `./web/comfyui/`
-- Purpose: Widgets and UI logic that ComfyUI loads as custom node extensions
-- Tech stack: Vanilla JS + Vue.js widgets (in `./vue-widgets/` and built to `./web/comfyui/vue-widgets/`)
-- Widget styling: Primary styles in `./web/comfyui/lm_styles.css` (NOT `./static/css/`)
-- Development: No npm build step for these widgets (Vue widgets use build system)
-
-### Widget Development Guidelines
-- Use `app.registerExtension()` to register ComfyUI extensions (ComfyUI integration layer)
-- Use `node.addDOMWidget()` for custom DOM widgets
-- Widget styles should follow the patterns in `./web/comfyui/lm_styles.css`
-  - Selected state: `rgba(66, 153, 225, 0.3)` background, `rgba(66, 153, 225, 0.6)` border
-  - Hover state: `rgba(66, 153, 225, 0.2)` background
-  - Color palette matches the Lora Manager accent color (blue #4299e1)
-  - Use oklch() for color values when possible (defined in `./static/css/base.css`)
-- Vue widget components are in `./vue-widgets/src/components/` and built to `./web/comfyui/vue-widgets/`
-- When modifying widget styles, check `./web/comfyui/lm_styles.css` for consistency with other ComfyUI 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`

-### Key Patterns
-
-**Dual Mode Operation:**
-- ComfyUI plugin mode: Integrates with ComfyUI's PromptServer, uses folder_paths
-- Standalone mode: Mocks ComfyUI dependencies via `standalone.py`, reads paths from settings.json
+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"`
 
-**Settings Management:**
-- Settings stored in user directory (via `platformdirs`) or portable mode (in repo)
-- Migration system tracks settings schema version
-- Template in `settings.json.example` defines defaults
+### Backend (Python)
 
-**Model Scanning Flow:**
-1. Scanner walks folder paths, computes file hashes
-2. Hash-based deduplication prevents duplicate processing
-3. Metadata extracted from safetensors headers
-4. Persistent cache stores results in SQLite
-5. Background sync fetches CivitAI/CivArchive metadata
-6. WebSocket broadcasts updates to connected clients
+**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
 
-**Recipe System:**
-- Recipes store LoRA combinations with parameters
-- Supports import from workflow JSON, PNG metadata
-- Images associated with recipes via sibling file detection
-- Enrichment adds model metadata for display
+**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)
 
-**Frontend-Backend Communication:**
-- REST API for CRUD operations
-- WebSocket for real-time progress updates (downloads, scans)
-- API endpoints follow `/loras/*` pattern
+**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

 - 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 with camelCase
-- Files use `*_widget.js` suffix for ComfyUI widgets

-- Standalone mode: Use `settings.json` (copy from `settings.json.example`)
-- Portable mode: Set `"use_portable_settings": true` in settings.json
-
-**API Integration:**
-- CivitAI API key required for downloads (add to settings)
-- CivArchive API used as fallback for deleted models
-- Metadata archive database available for offline metadata
-
-**Symlink Handling:**

-
-**ComfyUI Node Development:**
-- Nodes defined in `py/nodes/`, registered in `__init__.py`
-- Frontend widgets in `web/comfyui/`, matched by node type
-- Use `WEB_DIRECTORY = "./web/comfyui"` convention
-
-**Recipe Image Association:**
-- Recipes scan for sibling images in same directory
-- Supports repair/migration of recipe image paths
-- See `py/services/recipe_scanner.py` for implementation details
+- **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

-## Why Are All Features for Supporters Only?
+## Why Supporter Access?
 
-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.
+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.
 
-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.
+Supporter-exclusive features help ensure the long-term sustainability of LoRA Manager, allowing continuous updates, new features, and better performance for everyone.
 
-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._)
+Every contribution directly fuels development and keeps the core LoRA Manager free and open-source. In addition to monthly supporters, one-time donation supporters will also receive a license key, with the duration scaling according to the contribution amount. Thank you for helping keep this project alive and growing. ❤️

+# 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)

+
+### 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

+        
+    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

+        
+    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:

+    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"

+    """
+    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
+```
+

+
+## Phase 3 Completion Summary (2026-02-11)
+
+### Completed Items
+
+1. **Centralized Test Fixtures** ✅
+   - Added `mock_downloader` fixture to `tests/conftest.py`
+     - Configurable mock with `should_fail` and `return_value` attributes
+     - Records all download calls for verification
+   - Added `mock_websocket_manager` fixture to `tests/conftest.py`
+     - Recording WebSocket manager that captures all broadcast payloads
+     - Includes helper method `get_payloads_by_type()` for filtering
+   - Added `reset_singletons` autouse fixture to `tests/conftest.py`
+     - Resets DownloadManager, ServiceRegistry, ModelScanner, and SettingsManager
+     - Ensures test isolation and prevents singleton pollution
+
+2. **Split Large Test Files** ✅
+   - Split `tests/services/test_download_manager.py` (1422 lines) into:
+     - `test_download_manager_basic.py` - Core functionality (12 tests)
+     - `test_download_manager_error.py` - Error handling and execution (15 tests)
+     - `test_download_manager_concurrent.py` - Advanced scenarios (6 tests)
+   - Split `tests/utils/test_cache_paths.py` (530 lines) into:
+     - `test_cache_paths_resolution.py` - Path resolution and CacheType tests (11 tests)

+
+### Test Results
+- **Download Manager Tests:** 33/33 passing across 3 files
+- **Cache Paths Tests:** 29/29 passing across 3 files
+- **Total Tests Maintained:** All existing tests preserved and organized
+
+---
+
+## Phase 3: Architecture & Maintainability (P2) - Week 5-6
+
+### 3.1 Centralize Test Fixtures
+
+**Create `tests/conftest.py` improvements:**
+
+```python
+# tests/conftest.py additions
+
+@pytest.fixture
+def mock_downloader():
+    """Provide a configurable mock downloader."""
+    class MockDownloader:
+        def __init__(self):
+            self.download_calls = []
+            self.should_fail = False
+            
+        async def download_file(self, url, target_path, **kwargs):
+            self.download_calls.append({"url": url, "target_path": target_path})
+            if self.should_fail:
+                return False, "Download failed"
+            return True, str(target_path)
+    
+    return MockDownloader()
+
+@pytest.fixture
+def mock_websocket_manager():
+    """Provide a recording WebSocket manager."""
+    class RecordingWebSocketManager:
+        def __init__(self):
+            self.payloads = []
+            
+        async def broadcast(self, payload):
+            self.payloads.append(payload)
+            
+    return RecordingWebSocketManager()
+
+@pytest.fixture
+def mock_scanner():
+    """Provide a mock model scanner with configurable cache."""
+    # ... existing MockScanner but improved ...
+    
+@pytest.fixture(autouse=True)
+def reset_singletons():
+    """Reset all singletons before each test."""
+    # Centralized singleton reset
+    DownloadManager._instance = None
+    ServiceRegistry.clear_services()
+    ModelScanner._instances.clear()
+    yield
+    # Cleanup
+    DownloadManager._instance = None
+    ServiceRegistry.clear_services()
+    ModelScanner._instances.clear()
+```
+
+### 3.2 Split Large Test Files
+
+**Target Files:**
+- `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
+```
+

+# 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

+
+### 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
