chore(release): bump version to v1.1.4

- save_metadata_updates now trims/lowercases/dedupes tags on write
- ModelFilterSet tag matching is now case-insensitive (both include/exclude)
- Removed redundant .lower() calls in tag_update_service.py

+name: lora-manager-runtime-context
+description: Inspect ComfyUI LoRA Manager runtime configuration and local diagnostic state. Use when debugging LoRA Manager issues that require locating or reading settings.json, active library paths, model metadata JSON sidecars, recipe metadata JSON files, example image folders, SQLite caches, symlink maps, download history, aria2 state, or other cache files under the LoRA Manager user config directory.
+---
+
+# LoRA Manager Runtime Context
+
+## Core Rules
+
+- Treat runtime state as local user data. Prefer read-only inspection unless the user explicitly asks for mutation.
+- Never print secret-like settings values. Redact keys containing `key`, `token`, `secret`, `password`, `auth`, or `credential`, including `civitai_api_key`.
+- Resolve paths from the runtime configuration before guessing. In this environment the settings file is normally `/home/miao/.config/ComfyUI-LoRA-Manager/settings.json`, but portable settings can override this through the repository `settings.json`.
+- Use the active library when selecting per-library caches and paths. Read `active_library` from settings; fall back to `default` if missing.
+- Normalize and expand `~` before comparing paths. Symlinks are common in this repo.
+
+## Quick Start
+
+Use the bundled helper for a safe first pass:
+
+```bash
+python .agents/skills/lora-manager-runtime-context/scripts/inspect_runtime_context.py summary
+python .agents/skills/lora-manager-runtime-context/scripts/inspect_runtime_context.py caches
+```
+
+The script redacts sensitive settings, opens SQLite databases read-only, and reports inaccessible or locked databases as warnings.
+
+For focused checks:
+
+```bash
+python .agents/skills/lora-manager-runtime-context/scripts/inspect_runtime_context.py recipes
+python .agents/skills/lora-manager-runtime-context/scripts/inspect_runtime_context.py model --path /path/to/model.safetensors
+python .agents/skills/lora-manager-runtime-context/scripts/inspect_runtime_context.py sqlite --db /path/to/cache.sqlite --limit 3
+```
+
+## Runtime Path Rules
+
+- Settings directory: use `py/utils/settings_paths.py`. Default platform path is `platformdirs.user_config_dir("ComfyUI-LoRA-Manager", appauthor=False)`.
+- Settings file: `<settings_dir>/settings.json`.
+- Cache root: `<settings_dir>/cache`.
+- Canonical cache files:
+  - Model cache: `cache/model/<active_library>.sqlite`.
+  - Recipe cache: `cache/recipe/<active_library>.sqlite`.
+  - Model update cache: `cache/model_update/<active_library>.sqlite`.
+  - Recipe FTS: `cache/fts/recipe_fts.sqlite`.
+  - Tag FTS: `cache/fts/tag_fts.sqlite`.
+  - Symlink map: `cache/symlink/symlink_map.json`.
+  - Download history: `cache/download_history/downloaded_versions.sqlite`.
+  - aria2 state: `cache/aria2/downloads.json`.
+- Legacy cache locations may exist; prefer canonical paths unless diagnosing migrations.
+
+## Data Location Rules
+
+- Model roots come from `settings.folder_paths` and the active library payload under `settings.libraries[active_library]`.
+- Model metadata JSON sidecars live next to the model file as `<model basename>.metadata.json`.
+- Recipes root is `settings.recipes_path` when it is a non-empty string. If empty, use the first configured LoRA root plus `/recipes`.
+- Recipe JSON files are named `*.recipe.json` under the recipes root and may be nested in folders.
+- Example image root is `settings.example_images_path`.
+- If multiple libraries are configured, example images are stored under `<example_images_path>/<sanitized_library>/<sha256>/`; otherwise they are under `<example_images_path>/<sha256>/`.
+
+## Useful Cache Tables
+
+- Model cache: `models`, `model_tags`, `hash_index`, `excluded_models`.
+- Recipe cache: `recipes`, `cache_metadata`.
+- Model update cache: `model_update_status`, `model_update_versions`.
+- Tag FTS cache: `tags`, `fts_metadata`, plus FTS internal tables.
+- Recipe FTS cache: `recipe_rowid`, `fts_metadata`, plus FTS internal tables.
+- Download history: `downloaded_model_versions`.
+
+Prefer querying only counts, schema, and a few sample rows unless the user asks for full output.

+# Embeddings Usage Tracking — Hybrid Approach (Plan C)
+
+> **Status**: Reference document for future implementation
+> **Current implementation**: Plan A (prompt text parsing only, see `usage_stats.py:_process_embeddings`)
+> **Next step**: Add Plan B as a supplement when edge-case coverage is needed
+
+## Problem
+
+Embeddings in ComfyUI are not loaded through dedicated ComfyUI nodes like LoRAs or
+Checkpoints. They are resolved during CLIP tokenization when the prompt text contains
+`embedding:<name>` syntax (see `comfy/sd1_clip.py:SDTokenizer.tokenize_with_weights`).
+
+This means the existing metadata_collector hook (which intercepts node execution via
+`_map_node_over_list`) cannot capture embeddings the same way it captures LoRAs and
+checkpoints — there is no "EmbeddingLoader" node to intercept.
+
+## Solution Architecture
+
+The hybrid approach combines **two complementary mechanisms** to capture embedding
+usage from all possible paths.

+## Plan B Detail — Monkey-patch `load_embed`
+
+### Target Function
+
+**`comfy.sd1_clip.load_embed(embedding_name, embedding_directory, embedding_size, embed_key=None)`**
+at line 415 of `sd1_clip.py`.
+
+This is the **single choke point** for all embedding file loads in ComfyUI. Every
+CLIP variant (SD1, SDXL, SD3, Flux) calls this same function.
+
+### Implementation Sketch
+
+```python
+# In metadata_collector/metadata_hook.py (or a new module)
+import comfy.sd1_clip as sd1_clip
+
+_original_load_embed = sd1_clip.load_embed
+
+def _patched_load_embed(embedding_name, embedding_directory, embedding_size, embed_key=None):
+    result = _original_load_embed(
+        embedding_name, embedding_directory, embedding_size, embed_key
+    )
+    if result is not None:
+        _record_embedding_usage(embedding_name)
+    return result
+
+sd1_clip.load_embed = _patched_load_embed
+```
+
+### Prompt ID Association
+
+The challenge is associating the `load_embed` call with the current `prompt_id`.
+Options:
+
+1. **Thread-local / contextvar**: Store current `prompt_id` in a `contextvars.ContextVar`
+   that the metadata_collector sets at the start of each prompt execution.
+
+2. **MetadataRegistry singleton**: The MetadataRegistry already has `current_prompt_id`.
+   The patch can read it directly since both run in the same thread.
+
+3. **Lazy aggregation**: Instead of associating with prompt_id at load time, collect
+   all loaded embedding names in a global set during execution, then flush to
+   UsageStats after the prompt completes.
+
+### Files to Patch
+
+| File | Function | Coverage |
+|------|----------|----------|
+| `comfy/sd1_clip.py:415` | `load_embed()` | Primary — SD1.x, SDXL, SD3, Flux |
+| `comfy/sdxl_clip.py` | Not needed (calls `sd1_clip.SDTokenizer`) | — |
+| `comfy/text_encoders/sd3_clip.py` | Not needed (calls `sd1_clip.SDTokenizer`) | — |
+| `comfy/text_encoders/flux.py` | Not needed (calls `sd1_clip.SDTokenizer`) | — |
+
+The SD1 tokenizer is the base class for all CLIP variants' tokenizers, so patching
+`load_embed` covers them all.
+
+### Edge Cases
+
+| Edge Case | Plan A | Plan B |
+|-----------|--------|--------|
+| `embedding:name` in CLIPTextEncode | ✅ | ✅ |
+| `embedding:name` in CLIPTextEncodeFlux | ✅ | ✅ |
+| `embedding:name` in PromptLM (LoRA Manager) | ✅ | ✅ |
+| `embedding:name` in WAS_Text_to_Conditioning | ✅ | ✅ |
+| Custom node that loads embedding programmatically | ❌ | ✅ |
+| Embedding loaded multiple times in same prompt | ✅ (dedup via set) | ✅ (dedup via set) |
+| Embedding file not found | N/A | ✅ (can log) |
+| Embedding dimension mismatch | N/A | ✅ (can log) |
+| Text encoder with non-standard tokenizer (LLaMA, T5...) | Partial | ✅ (if it calls load_embed) |
+
+## Migration Path: Standalone → Hybrid
+
+### Phase 1 — Plan A (当前状态)
+- Prompt text parsing only
+- No monkey-patching required
+- Covers all standard workflows
+
+### Phase 2 — Enable Plan B (未来工作)
+1. Add monkey-patch of `load_embed` in `metadata_collector/metadata_hook.py` (alongside
+   the existing `_map_node_over_list` hook)
+2. Collect loaded embedding names in a `set()` on the registry
+3. In `UsageStats._process_embeddings()`, merge the Plan A results (from prompt text)
+   with the Plan B results (from the patch)
+4. Add `prompt_data` field on MetadataRegistry to store loaded embeddings per prompt
+
+### Deduplication
+
+```python
+# Merge Plan A + Plan B results in _process_embeddings
+plan_a_names = extract_from_prompt_texts(prompts_data)
+plan_b_names = registry.get_loaded_embeddings(prompt_id)
+
+all_names = plan_a_names | plan_b_names
+```
+
+## Testing the Hybrid
+
+| Scenario | What to verify |
+|----------|---------------|
+| Standard `embedding:name` in prompt | Plan A captures it |
+| Embedding loaded by custom node script | Plan B captures it |
+| Both paths fire for same embedding | No double-counting (dedup) |
+| Embedding name resolves to hash | EmbeddingScanner.get_hash_by_filename works |
+| No embedding scanner available | Graceful skip, no crash |
+| Missing embedding file | Plan B logs warning, Plan A skips gracefully |
+| Empty prompt | No crash, no entries |
+| Standalone mode | Both plans disabled gracefully |
+
+## Key Files Reference
+
+| File | Role |
+|------|------|
+| `py/utils/usage_stats.py` | Core — `_process_embeddings()` for Plan A |
+| `py/metadata_collector/constants.py` | `EMBEDDINGS` category constant |
+| `py/metadata_collector/metadata_hook.py` | Future — monkey-patch for Plan B |
+| `py/services/embedding_scanner.py` | Hash resolution service |
+| `py/routes/stats_routes.py` | Already handles `usage_data.get('embeddings', {})` |
+| `comfy/sd1_clip.py` (ComfyUI) | `load_embed()` — Plan B target |

 ## Python Code Style
 
-### Imports

-- Mock ComfyUI dependencies in tests using `tests/conftest.py` patterns
+- PEP 8 with 4-space indentation, type hints required
-
-### Formatting & Types
-
-- PEP 8 with 4-space indentation
-- Type hints required for function signatures and class attributes
-- Use `TYPE_CHECKING` guard for type-checking-only imports
-- Prefer dataclasses for simple data containers
-- Use `Optional[T]` for nullable types, `Union[T, None]` only when necessary
 
 ### Naming Conventions
 
-- Files: `snake_case.py` (e.g., `model_scanner.py`, `lora_service.py`)
+- Files: `snake_case.py`, Classes: `PascalCase`, Functions/vars: `snake_case`
-- Classes: `PascalCase` (e.g., `ModelScanner`, `LoraService`)
+- Constants: `UPPER_SNAKE_CASE`, Private: `_protected`, `__mangled`
-- Functions/variables: `snake_case` (e.g., `get_instance`, `model_type`)
-- Constants: `UPPER_SNAKE_CASE` (e.g., `VALID_LORA_TYPES`)
-- Private members: `_single_underscore` (protected), `__double_underscore` (name-mangled)
 
-### Error Handling
+### Error Handling & Async
 
-- Use `logging.getLogger(__name__)` for module-level loggers
+- Use `logging.getLogger(__name__)`, define custom exceptions in `py/services/errors.py`
-- Define custom exceptions in `py/services/errors.py`
+- `async def` for I/O, `@pytest.mark.asyncio` for async tests
-- Use `asyncio.Lock` for thread-safe singleton patterns
+- Singleton with `asyncio.Lock`: see `ModelScanner.get_instance()`
-- Raise specific exceptions with descriptive messages
+- Return `aiohttp.web.json_response` or `web.Response`
-- Log errors at appropriate levels (DEBUG, INFO, WARNING, ERROR, CRITICAL)
 
-### Async Patterns
+### Testing
 
-- Use `async def` for I/O-bound operations
+- `pytest` with `--import-mode=importlib`
-- Mark async tests with `@pytest.mark.asyncio`
+- Fixtures in `tests/conftest.py`, use `tmp_path_factory` for isolation
-- Use `async with` for context managers
+- Mark tests needing real paths: `@pytest.mark.no_settings_dir_isolation`
-- Singleton pattern with class-level locks: see `ModelScanner.get_instance()`
+- Mock ComfyUI dependencies via conftest patterns
-- Use `aiohttp.web.Response` for HTTP responses
 
-### Testing Patterns
+## JavaScript/TypeScript Code Style
-
-- Use `pytest` with `--import-mode=importlib`
-- Fixtures in `tests/conftest.py` handle ComfyUI mocking
-- Use `@pytest.mark.no_settings_dir_isolation` for tests needing real paths
-- Test files: `tests/test_*.py`
-- Use `tmp_path_factory` for temporary directory isolation
-
-## JavaScript Code Style
 
 ### Imports & Modules
 
-- ES modules with `import`/`export`
+- ES modules: `import { app } from "../../scripts/app.js"` for ComfyUI
-- Use `import { app } from "../../scripts/app.js"` for ComfyUI integration
+- Vue: `import { ref, computed } from 'vue'`, type imports: `import type { Foo }`
-- Export named functions/classes: `export function foo() {}`
+- Export named functions: `export function foo() {}`
-- Widget files use `*_widget.js` suffix
 
 ### Naming & Formatting
 
-- camelCase for functions, variables, object properties
+- camelCase for functions/vars/props, PascalCase for classes
-- PascalCase for classes/constructors
+- Constants: `UPPER_SNAKE_CASE`, Files: `snake_case.js` or `kebab-case.js`
-- Constants: `UPPER_SNAKE_CASE` (e.g., `CONVERTED_TYPE`)
-- Files: `snake_case.js` or `kebab-case.js`
 - 2-space indentation preferred (follow existing file conventions)
+- Vue Single File Components: `<script setup lang="ts">` preferred
 
 ### Widget Development
 
-- Use `app.registerExtension()` to register ComfyUI extensions
+- ComfyUI: `app.registerExtension()`, `node.addDOMWidget(name, type, element, options)`
-- Use `node.addDOMWidget(name, type, element, options)` for custom widgets
+- Event handlers via `addEventListener` or widget callbacks
-- Event handlers attached via `addEventListener` or widget callbacks
+- Shared utilities: `web/comfyui/utils.js`
-- See `web/comfyui/utils.js` for shared utilities
+
+### Vue Composables Pattern
+
+- Use composition API: `useXxxState(widget)`, return reactive refs and methods
+- Guard restoration loops with flag: `let isRestoring = false`
+- Build config from state: `const buildConfig = (): Config => { ... }`
 
 ## Architecture Patterns
 
 ### Service Layer
 
-- Use `ServiceRegistry` singleton for dependency injection
+- `ServiceRegistry` singleton for DI, services use `get_instance()` classmethod
-- Services follow singleton pattern via `get_instance()` class method
 - 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
+- `BaseModelService` base for LoRA, Checkpoint, Embedding
-- ModelScanner provides file discovery and hash-based deduplication
+- `ModelScanner` for file discovery, hash deduplication
-- Persistent cache in SQLite via `PersistentModelCache`
+- `PersistentModelCache` (SQLite) for persistence
-- Metadata sync from CivitAI/CivArchive via `MetadataSyncService`
+- Route registrars: `ModelRouteRegistrar`, endpoints: `/loras/*`, `/checkpoints/*`, `/embeddings/*`
-
+- WebSocket via `WebSocketManager` for real-time updates
-### 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`
 
 ### Recipe System
 
-- Base metadata in `py/recipes/base.py`
+- Base: `py/recipes/base.py`, Enrichment: `RecipeEnrichmentService`
-- Enrichment adds model metadata: `RecipeEnrichmentService`
+- Parsers: `py/recipes/parsers/`
-- Parsers for different formats in `py/recipes/parsers/`
 
 ## Important Notes
 
-- Always use English for comments (per copilot-instructions.md)
+- ALWAYS use English for comments (per copilot-instructions.md)
-- Dual mode: ComfyUI plugin (uses folder_paths) vs standalone (reads settings.json)
+- 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
+- Run `python scripts/sync_translation_keys.py` after adding UI strings to `locales/en.json`
-- WebSocket broadcasts for real-time updates (downloads, scans)
+- Symlinks require normalized paths
-- Symlink handling requires normalized paths
+
-- API endpoints follow `/loras/*`, `/checkpoints/*`, `/embeddings/*` patterns
+## Git / Commit Messages
-- Run `python scripts/sync_translation_keys.py` after UI string updates
+
+- Follow the style of recent repository commits when writing commit messages
+- Prefer the repo's existing `feat(...)`, `fix(...)`, `chore:` style where applicable
+- If the user has provided a GitHub issue link or issue ID for the task, mention that issue in the commit message, for example `(#871)`
+- When unrelated local changes exist, stage and commit only the files relevant to the requested task
 
 ## Frontend UI Architecture
 
-This project has two distinct UI systems:
+### 1. Standalone Web UI
-
-### 1. Standalone Lora Manager Web UI
 - Location: `./static/` and `./templates/`
-- Purpose: Full-featured web application for managing LoRA models
+- Tech: Vanilla JS + CSS, served by standalone server
-- Tech stack: Vanilla JS + CSS, served by the standalone server
+- Tests via npm in root directory
-- Development: Uses npm for frontend testing (`npm test`, `npm run test:watch`, etc.)
 
 ### 2. ComfyUI Custom Node Widgets
-- Location: `./web/comfyui/`
+- Location: `./web/comfyui/` (Vanilla JS) + `./vue-widgets/` (Vue)
-- Purpose: Widgets and UI logic that ComfyUI loads as custom node extensions
+- Primary styles: `./web/comfyui/lm_styles.css` (NOT `./static/css/`)
-- Tech stack: Vanilla JS + Vue.js widgets (in `./vue-widgets/` and built to `./web/comfyui/vue-widgets/`)
+- Vue builds to `./web/comfyui/vue-widgets/`, typecheck via `vue-tsc`
-- 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

 ## Architecture
 
-### Backend Structure (Python)
+### Dual Mode Operation
 
-**Core Entry Points:**
+The system runs in two modes:
-- `__init__.py` - ComfyUI plugin entry point, registers nodes and routes
+- **ComfyUI plugin mode**: Integrates with ComfyUI's PromptServer, uses `folder_paths` for model discovery
-- `standalone.py` - Standalone server that mocks ComfyUI dependencies
+- **Standalone mode**: `standalone.py` mocks ComfyUI dependencies, reads paths from `settings.json`
-- `py/lora_manager.py` - Main LoraManager class that registers HTTP routes
-
-**Service Layer** (`py/services/`):
-- `ServiceRegistry` - Singleton service registry for dependency management
-- `ModelServiceFactory` - Factory for creating model services (LoRA, Checkpoint, Embedding)
-- Scanner services (`lora_scanner.py`, `checkpoint_scanner.py`, `embedding_scanner.py`) - Model file discovery and indexing
-- `model_scanner.py` - Base scanner with hash-based deduplication and metadata extraction
-- `persistent_model_cache.py` - SQLite-based cache for model metadata
-- `metadata_sync_service.py` - Syncs metadata from CivitAI/CivArchive APIs
-- `civitai_client.py` / `civarchive_client.py` - API clients for external services
-- `downloader.py` / `download_manager.py` - Model download orchestration
-- `recipe_scanner.py` - Recipe file management and image association
-- `settings_manager.py` - Application settings with migration support
-- `websocket_manager.py` - WebSocket broadcasting for real-time updates
-- `use_cases/` - Business logic orchestration (auto-organize, bulk refresh, downloads)
-
-**Routes Layer** (`py/routes/`):
-- Route registrars organize endpoints by domain (models, recipes, previews, example images, updates)
-- `handlers/` - Request handlers implementing business logic
-- Routes use aiohttp and integrate with ComfyUI's PromptServer
-
-**Recipe System** (`py/recipes/`):
-- `base.py` - Base recipe metadata structure
-- `enrichment.py` - Enriches recipes with model metadata
-- `merger.py` - Merges recipe data from multiple sources
-- `parsers/` - Parsers for different recipe formats (PNG, JSON, workflow)
-
-**Custom Nodes** (`py/nodes/`):
-- `lora_loader.py` - LoRA loader nodes with preset support
-- `save_image.py` - Enhanced save image with pattern-based filenames
-- `trigger_word_toggle.py` - Toggle trigger words in prompts
-- `lora_stacker.py` - Stack multiple LoRAs
-- `prompt.py` - Prompt node with autocomplete
-- `wanvideo_lora_select.py` - WanVideo-specific LoRA selection
-
-**Configuration** (`py/config.py`):
-- Manages folder paths for models, checkpoints, embeddings
-- Handles symlink mappings for complex directory structures
-- Auto-saves paths to settings.json in ComfyUI mode
-
-### Frontend Structure (JavaScript)
-
-**ComfyUI Widgets** (`web/comfyui/`):
-- Vanilla JavaScript ES modules extending ComfyUI's LiteGraph-based UI
-- `loras_widget.js` - Main LoRA selection widget with preview

-- `top_menu_extension.js` - Adds "Launch LoRA Manager" menu item
-- `trigger_word_highlight.js` - Syntax highlighting for trigger words
-- `utils.js` - Shared utilities and API helpers
-
-**Widget Development:**
-- Widgets use `app.registerExtension` and `getCustomWidgets` hooks
-- `node.addDOMWidget(name, type, element, options)` embeds HTML in nodes
-- See `docs/dom_widget_dev_guide.md` for complete DOMWidget development guide
-
-**Web Source** (`web-src/`):
-- Modern frontend components (if migrating from static)
-- `components/` - Reusable UI components
-- `styles/` - CSS styling
-
-### 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
 - Detection: `os.environ.get("LORA_MANAGER_STANDALONE", "0") == "1"`
 
-**Settings Management:**
+### Backend (Python)
-- 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
 
-**Model Scanning Flow:**
+**Entry points:**
-1. Scanner walks folder paths, computes file hashes
+- `__init__.py` — ComfyUI plugin entry: registers nodes via `NODE_CLASS_MAPPINGS`, sets `WEB_DIRECTORY`, calls `LoraManager.add_routes()`
-2. Hash-based deduplication prevents duplicate processing
+- `standalone.py` — Standalone server: mocks `folder_paths` and node modules, starts aiohttp server
-3. Metadata extracted from safetensors headers
+- `py/lora_manager.py` — Main `LoraManager` class that registers all HTTP routes
-4. Persistent cache stores results in SQLite
-5. Background sync fetches CivitAI/CivArchive metadata
-6. WebSocket broadcasts updates to connected clients
 
-**Recipe System:**
+**Service layer** (`py/services/`):
-- Recipes store LoRA combinations with parameters
+- `ServiceRegistry` singleton for dependency injection; services follow `get_instance()` singleton pattern
-- Supports import from workflow JSON, PNG metadata
+- `BaseModelService` abstract base → `LoraService`, `CheckpointService`, `EmbeddingService`
-- Images associated with recipes via sibling file detection
+- `ModelScanner` base → `LoraScanner`, `CheckpointScanner`, `EmbeddingScanner` for file discovery with hash-based deduplication
-- Enrichment adds model metadata for display
+- `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:**
+**Routes** (`py/routes/`):
-- REST API for CRUD operations
+- Route registrars organize endpoints by domain: `ModelRouteRegistrar`, `RecipeRouteRegistrar`, etc.
-- WebSocket for real-time progress updates (downloads, scans)
+- Request handlers in `py/routes/handlers/` implement route logic
-- API endpoints follow `/loras/*` pattern
+- API endpoints follow `/loras/*`, `/checkpoints/*`, `/embeddings/*` patterns
+- All routes use aiohttp, return `web.json_response` or `web.Response`
+
+**Recipe system** (`py/recipes/`):
+- `base.py` — Recipe metadata structure
+- `enrichment.py` — Enriches recipes with model metadata
+- `parsers/` — Parsers for PNG metadata, JSON, and workflow formats
+
+**Custom nodes** (`py/nodes/`):
+- Each node class has a `NAME` class attribute used as key in `NODE_CLASS_MAPPINGS`
+- Standard ComfyUI node pattern: `INPUT_TYPES()` classmethod, `RETURN_TYPES`, `FUNCTION`
+- All nodes registered in `__init__.py`
+
+**Configuration** (`py/config.py`):
+- Manages folder paths for models, handles symlink mappings
+- Auto-saves paths to settings.json in ComfyUI mode
+
+### Frontend — Two Distinct UI Systems
+
+#### 1. Standalone Manager Web UI
+- **Location:** `static/` (JS/CSS) and `templates/` (HTML)
+- **Tech:** Vanilla JS + CSS, served by standalone server
+- **Structure:** `static/js/core.js` (shared), `loras.js`, `checkpoints.js`, `embeddings.js`, `recipes.js`, `statistics.js`
+- **Tests:** `tests/frontend/**/*.test.js` (vitest + jsdom)
+
+#### 2. ComfyUI Custom Node Widgets
+- **Vanilla JS widgets:** `web/comfyui/*.js` — ES modules extending ComfyUI's LiteGraph UI
+  - `loras_widget.js` / `loras_widget_events.js` — Main LoRA selection widget
+  - `autocomplete.js` — Trigger word and embedding autocomplete
+  - `preview_tooltip.js` — Model card preview tooltips
+  - `top_menu_extension.js` — "Launch LoRA Manager" menu item
+  - `utils.js` — Shared utilities and API helpers
+  - Widget styling in `web/comfyui/lm_styles.css` (NOT `static/css/`)
+- **Vue widgets:** `vue-widgets/src/` → built to `web/comfyui/vue-widgets/`
+  - Vue 3 + TypeScript + PrimeVue + vue-i18n
+  - Vite build with CSS-injected-by-JS plugin
+  - Components: `LoraPoolWidget`, `LoraRandomizerWidget`, `LoraCyclerWidget`, `AutocompleteTextWidget`
+  - Auto-built on ComfyUI startup via `py/vue_widget_builder.py`
+  - Tests: `vue-widgets/tests/**/*.test.ts` (vitest)
+
+**Widget registration pattern:**
+- Widgets use `app.registerExtension()` and `getCustomWidgets` hooks
+- `node.addDOMWidget(name, type, element, options)` embeds HTML in LiteGraph nodes
+- See `docs/dom_widget_dev_guide.md` for DOMWidget development guide
 
 ## Code Style
 
 **Python:**
-- PEP 8 with 4-space indentation
+- PEP 8, 4-space indentation, English comments only
-- snake_case for files, functions, variables
+- Use `from __future__ import annotations` for forward references
-- PascalCase for classes
+- Use `TYPE_CHECKING` guard for type-checking-only imports
-- Type hints preferred
-- English comments only (per copilot-instructions.md)
 - 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
+- ES modules, camelCase functions/variables, PascalCase classes
-- Files use `*_widget.js` suffix for ComfyUI widgets
+- Widget files use `*_widget.js` suffix
-- Prefer vanilla JS, avoid framework dependencies
+- Prefer vanilla JS for `web/comfyui/` widgets, avoid framework dependencies (except Vue widgets)
 
 ## Testing
 
-**Backend Tests:**
+**Backend (pytest):**
-- pytest with `--import-mode=importlib`
+- Config in `pytest.ini`: `--import-mode=importlib`, testpaths=`tests`
-- Test files: `tests/test_*.py`
+- Fixtures in `tests/conftest.py` handle ComfyUI dependency mocking
-- Fixtures in `tests/conftest.py`
+- Markers: `@pytest.mark.asyncio`, `@pytest.mark.no_settings_dir_isolation`
-- Mock ComfyUI dependencies using standalone.py patterns
+- Uses `tmp_path_factory` for directory isolation
-- Markers: `@pytest.mark.asyncio` for async tests, `@pytest.mark.no_settings_dir_isolation` for real paths
 
-**Frontend Tests:**
+**Frontend (vitest):**
-- Vitest with jsdom environment
+- Vanilla JS tests: `tests/frontend/**/*.test.js` with jsdom
-- Test files: `tests/frontend/**/*.test.js`
+- Vue widget tests: `vue-widgets/tests/**/*.test.ts` with jsdom + @vue/test-utils
 - Setup in `tests/frontend/setup.js`
-- Coverage via `npm run test:coverage`
 
-## Important Notes
+## Key Integration Points
 
-**Settings Location:**
+- **Settings:** Stored in user directory (via `platformdirs`) or portable mode (`"use_portable_settings": true`)
-- ComfyUI mode: Auto-saves folder paths to user settings directory
+- **CivitAI/CivArchive:** API clients for metadata sync and model downloads; CivitAI API key in settings
-- Standalone mode: Use `settings.json` (copy from `settings.json.example`)
+- **Symlink handling:** Config scans symlinks to map virtual→physical paths; fingerprinting prevents redundant rescans
-- Portable mode: Set `"use_portable_settings": true` in settings.json
+- **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
-**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

-## Overview
-
-The **LoRA Manager Civitai Extension** is a Browser extension designed to work seamlessly with [LoRA Manager](https://github.com/willmiao/ComfyUI-Lora-Manager) to significantly enhance your browsing experience on [Civitai](https://civitai.com).
-It also supports browsing on [CivArchive](https://civarchive.com/) (formerly CivitaiArchive).
-
-With this extension, you can:
-
-✅ Instantly see which models are already present in your local library  
-✅ Download new models with a single click  
-✅ Manage downloads efficiently with queue and parallel download support  
-✅ Keep your downloaded models automatically organized according to your custom settings    
-

-
----
-
-## 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.
-

-
-### Resources on Image Pages (2025-08-05) — now shows in-library indicators for image resources. ‘Import image as recipe’ coming soon!
-

-
----
-
-## 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!**

+# 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)

+# metadata.json Schema Documentation
+
+This document defines the complete schema for `.metadata.json` files used by Lora Manager. These sidecar files store model metadata alongside model files (LoRA, Checkpoint, Embedding).
+
+## Overview
+
+- **File naming**: `<model_name>.metadata.json` (e.g., `my_lora.safetensors` → `my_lora.metadata.json`)
+- **Format**: JSON with UTF-8 encoding
+- **Purpose**: Store model metadata, tags, descriptions, preview images, and Civitai/CivArchive integration data
+- **Extensibility**: Unknown fields are preserved via `_unknown_fields` mechanism for forward compatibility
+
+---
+
+## Base Fields (All Model Types)
+
+These fields are present in all model metadata files.
+
+| Field | Type | Required | Auto-Updated | Description |

+- `last_checked_at` — Timestamp of scan
+- `metadata_source` — Set based on metadata provider
+
+### Fields Set Once (Immutable After Import)
+
+These fields are set when the model is first imported/scanned and **never change** thereafter:
+
+- `modified` — Import timestamp (used for "Date Added" sorting)
+- `size` — File size at time of import/download
+

+
+- `model_name` — Display name
+- `tags` — Model tags

+### Required Fields (Must Always Exist)
+
+- `file_name`
+- `model_name` (defaults to `file_name` if not provided)
+- `file_path`
+- `size`
+- `modified`
+- `sha256` (LoRA: always required; Checkpoint: may be empty when `hash_status="pending"`)
+

-# 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

-#### 2.3.2 Tabs 设计
-
-保留横向 Tab 切换，但优化内容展示：
-
-| Tab | 内容 | 交互方式 |
-|-----|------|----------|
-| Description | About this version + Model Description | Accordion 折叠 |
-| Versions | 版本列表卡片 | 完整列表视图 |
-| Recipes | Recipe 卡片网格 | 网格布局 |
-
-**Accordion 行为**:
-- 手风琴模式：同时只能展开一个 section
-- 默认：About this version 展开，Description 折叠
-- 动画：300ms ease-out
-
-### 2.4 全局导航
-
-#### 2.4.1 Model 切换
-
-| 按键 | 功能 |
-|------|------|
-| ↑ | 上一个 Model |
-| ↓ | 下一个 Model |
-
-**切换动画**:
-1. 当前 Modal 淡出 (150ms)
-2. 加载新 Model 数据
-3. 新 Modal 淡入 (150ms)
-4. 保持当前 Tab 状态（不重置到默认）
-
-#### 2.4.2 首次使用提示
-
-Modal 首次打开时，顶部显示提示条：
-```
-┌─────────────────────────────────────────────────────────────┐
-│  💡 Tip: ↑↓ 切换模型 | ←→ 浏览示例 | I 查看参数 | ESC 关闭   │
-└─────────────────────────────────────────────────────────────┘
-```
-- 3 秒后自动淡出
-- 提供 "不再显示" 选项

+# Backend Testing Improvement Plan
+
+**Status:** Phase 4 Complete ✅  
+**Created:** 2026-02-11

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

+    3. DownloadManager executes actual download
+    4. Downloader makes HTTP request (to test server)
+    5. Progress is broadcast via WebSocket
+    6. File is saved and cache updated
+    """
+    # Setup test server with known file
+    test_file = tmp_path / "test_model.safetensors"
+    test_file.write_bytes(b"fake model data")
+    
+    # Start download
+    async with aiohttp.ClientSession() as session:
+        response = await session.post(
+            "http://localhost:8188/api/lm/download",
+            json={"urls": [f"http://localhost:{test_server.port}/test_model.safetensors"]}
+        )
+        assert response.status == 200
+        
+    # Verify file downloaded
+    downloaded = tmp_path / "downloads" / "test_model.safetensors"

+    # Verify WebSocket progress updates
+    assert len(ws_manager.broadcasts) > 0
+    assert any(b["status"] == "completed" for b in ws_manager.broadcasts)
+```
+
+**Recipe Flow Integration Test:**
+```python
+# tests/integration/test_recipe_flow.py
+@pytest.mark.integration
+@pytest.mark.asyncio
+async def test_recipe_analysis_and_save_flow(tmp_path):
+    """
+    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 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

+## Notes
+
+### Design Decisions
+- 采用macOS Settings模式而非长页面滚动模式
+- 左侧仅显示4个Section，不显示具体设置项
+- 移除折叠/展开功能，简化交互
+- Section标题使用accent色下划线强调
+
+### Technical Notes
+- 优先使用现有CSS变量
+- 保持向后兼容，不破坏现有设置存储逻辑
+- 移动端响应式：小屏幕单栏堆叠
+
+### Blockers
+None
+
+---
+
+**Next Action**: Start Phase 0 - CSS Updates
