-# QR Scanner Module Development Progress
-
-## Project Goal
-
-Create a self-contained, portable QR scanning page module that can be easily integrated into other WeChat Mini Programs. The module should include all scanning functionality in a single directory and accept an entry query parameter to redirect to different pages upon successful scan and verification.
-
-## Feature Checklist - Extracted from Existing Code
-
-### ✅ Core QR Processing
-- [ ] **WebAssembly QR Tool Integration** - `qrtool.wx.js` library for QR code processing (TODO: Add library)
-- [ ] **Dual Processing Modes**:
-  - [ ] Worker-based processing (iPhone devices) - `worker/index.js` (TODO: Implement)
-  - [ ] Synchronous processing (Android devices) - `precheck.js` (TODO: Implement)
-- [ ] **QR Pattern Validation** - Emblem-specific QR code pattern matching (TODO: Add validation)
-- [ ] **Frame Pre-checking** - Validate QR frames before full processing (TODO: Implement)
-- [ ] **Angle Detection** - QR code angle detection and correction (TODO: Implement)
-
-### ✅ Camera System
-- [x] **Native Camera Interface** - WeChat camera component integration ✅
-- [x] **Web-view Camera Fallback** - Integrated web-view for problematic devices ✅
-- [x] **Device-specific Camera Rules** - API-driven zoom and camera settings per phone model ✅
-- [x] **Loading State Management** - Spinner while camera rules load, prevents mode jumping ✅
-- [ ] **Dynamic Zoom Control** - Initial zoom + QR-found zoom adjustment (TODO: Implement)
-- [x] **Torch/Flash Control** - Manual and automatic torch management ✅
-- [ ] **Auto-torch Detection** - API-based torch recommendation system (TODO: Implement API integration)
-
-### ✅ UI Components & Visual Feedback
-- [x] **QR Targeting Overlay** - Animated corner arcs for QR positioning ✅
-- [x] **Visual State Indicators** - Progress states (searching, found, verifying) ✅
-- [x] **Hint Text System** - Dynamic user guidance messages ✅
-- [x] **Debug Overlay** - Development/diagnostic information display ✅
-- [x] **Modal System**: ✅
-  - [x] Verification spinner (`verifyspin`) ✅
-  - [x] Failed verification (`verifyfailed`) ✅
-  - [x] Scan guide tutorial (`scanguide`) ✅
-  - [x] Service modal (`servicemodal`) ✅
-  - [x] Tooltip component (`tooltip`) ✅
-
-### ✅ API Integration & Data Flow
-- [ ] **Image Upload System** - Multi-frame submission to backend
-- [ ] **Verification Pipeline** - QR code verification with themblem.com API
-- [ ] **Camera Rules API** - Device-specific camera configuration fetching
-- [ ] **Auto-torch API** - Torch recommendation based on QR code
-- [ ] **Event Tracking** - Frame upload and analytics events
-- [ ] **Session Management** - Unique session ID generation and tracking
-
-### ✅ Phone Model & Runtime Configuration
-- [x] **Device Detection** - Phone model identification and global data storage ✅
-- [x] **Processing Mode Selection** - Worker vs synchronous based on device type ✅
-- [x] **Camera Sensitivity Adjustment** - Device-specific camera sensitivity settings ✅
-
-### ✅ Navigation & Integration
-- [x] **Entry Point Configuration** - Support for return page query parameter ✅
-- [x] **Return Page Routing** - Navigate to specified page after successful scan and verification ✅
-
-### ✅ Assets & Resources
-- [x] **Static Image Assets**: ✅
-  - [x] QR targeting arcs (`arc.png`) ✅
-  - [x] QR positioning markers (`qrmarkers.png`) ✅ 
-  - [x] UI action icons (`play-button.png`, `flash-button.png`) ✅
-- [ ] **WebAssembly Binary** - `qrtool.wx.js` QR processing library (TODO: Add for QR detection)
-- [x] **CSS Animations** - Pure CSS animations for QR targeting arcs and loading spinner ✅
-
-## Integration Requirements
-
-### Required Query Parameters
-- `return_page` - Target page to navigate to after successful verification
-
-### Required Global Dependencies
-- WeChat Mini Program camera API
-- WebAssembly support  
-- Worker thread support (iOS)
-- Canvas 2D context for image processing
-
-### External API Dependencies
-- `{server_url}/api/v1/camera-rules/` - Camera configuration
-- `{server_url}/api/v1/check-auto-torch/` - Torch recommendations  
-- Verification endpoint for QR code validation
-- Event tracking endpoints
-
-## Success Criteria
-
-1. **Self-contained Module** - All functionality within single directory
-2. **Platform Portability** - Easy integration into other mini programs
-3. **Device Compatibility** - Support for iOS/Android with appropriate fallbacks
-4. **Performance Optimization** - Efficient WebAssembly + Worker threading  
-5. **Robust Error Handling** - Graceful failure modes and user feedback
-6. **Configurable Integration** - Flexible redirect and mode parameters
-7. **Asset Independence** - Bundled resources with minimal external dependencies
-8. **No External Dependencies** - Cannot reference utils.js or other external files, all code must be inline
