chore(release): bump version to 0.9.16 and update release notes

Instead of always using default paths, downloads from the model versions
tab now target the same directory as the current in-library version.
Falls back silently to default paths if the current version path cannot
be resolved.

-### Imports
+### Imports & Formatting
 
-- Use `from __future__ import annotations` for forward references in type hints
-- Group imports: standard library, third-party, local (separated by blank lines)

-### Error Handling
+### Error Handling & Async
 
-- 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)
+- Use `logging.getLogger(__name__)`, define custom exceptions in `py/services/errors.py`
+- `async def` for I/O, `@pytest.mark.asyncio` for async tests
+- Singleton with `asyncio.Lock`: see `ModelScanner.get_instance()`
+- Return `aiohttp.web.json_response` or `web.Response`

+
+- Use composition API: `useXxxState(widget)`, return reactive refs and methods
+- Guard restoration loops with flag: `let isRestoring = false`
+- Build config from state: `const buildConfig = (): Config => { ... }`
 
 ## Architecture Patterns
 
 ### Service Layer
 
-- 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

-- PEP 8 with 4-space indentation
-- snake_case for files, functions, variables
-- PascalCase for classes
-- Type hints preferred
-- English comments only (per copilot-instructions.md)
+- PEP 8, 4-space indentation, English comments only
+- Use `from __future__ import annotations` for forward references
+- Use `TYPE_CHECKING` guard for type-checking-only imports
 - Loggers via `logging.getLogger(__name__)`
+- Custom exceptions in `py/services/errors.py`
+- Async patterns: `async def` for I/O, `@pytest.mark.asyncio` for async tests
+- Singleton pattern with class-level `asyncio.Lock` (see `ModelScanner.get_instance()`)
 
 **JavaScript:**
-- ES modules with camelCase
-- Files use `*_widget.js` suffix for ComfyUI widgets
-- Prefer vanilla JS, avoid framework dependencies

-- Coverage via `npm run test:coverage`
 
-## Important Notes
+## Key Integration Points
 
-**Settings Location:**
-- ComfyUI mode: Auto-saves folder paths to user settings directory
-- 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:**
-- Config scans symlinks to map virtual paths to physical locations
-- Preview validation uses normalized preview root paths
-- Fingerprinting prevents redundant symlink rescans
-
-**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. ❤️

-# Model Modal UI/UX 重构计划
-
-> **Status**: Phase 1 Complete ✓  
-> **Created**: 2026-02-06  
-> **Target**: v2.x Release
-
----
-
-## 1. 项目概述
-
-### 1.1 背景与问题
-
-当前 Model Modal 存在以下 UX 问题：
-
-1. **空间利用率低** - 固定 800px 宽度，大屏环境下大量留白
-2. **Tab 切换繁琐** - 4 个 Tab（Examples/Description/Versions/Recipes）隐藏了重要信息
-3. **Examples 浏览不便** - 需持续向下滚动，无快速导航
-4. **添加自定义示例困难** - 需滚动到底部，操作路径长
-
-### 1.2 设计目标
-
-- **空间效率**: 利用 header 以下、sidebar 右侧的全部可用空间
-- **浏览体验**: 类似 Midjourney 的沉浸式图片浏览
-- **信息架构**: 关键元数据固定可见，次要信息可折叠
-- **操作效率**: 直觉化的键盘导航，减少点击次数
-
----
-
-## 2. 设计方案
-
-### 2.1 布局架构: Split-View Overlay

+
+### 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

+
+**Priority 2: `py/services/persistent_recipe_cache.py`**
+```python
+# tests/services/test_persistent_recipe_cache.py
+class TestPersistentRecipeCache:
+    def test_initialization_creates_schema(self):
+        """Verify SQLite schema is created on first use."""

+
+**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

+    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
+```
+

+- **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
+```
+
