# Development Log - July 6, 2025

## Overview
🎨 **FEATURE MILESTONE ACHIEVED**: **Dot Files Exploration & Log File Rendering** + **Complete VeriDoc Logo Integration** - Enhanced file accessibility and professional branding across the entire application.

## 🚀 Major Feature Implementation - Morning Session

### Dot Files Exploration & Log File Rendering
**Comprehensive file access enhancement with dual feature implementation**:

#### Feature 1: Dot Files Exploration
- ✅ **Toggle Button**: Added 👁️/🙈 button in FILES panel header for hidden file visibility
- ✅ **Backend Integration**: Modified `FileTree.showHidden` property with API parameter sync
- ✅ **Event Management**: Implemented `toggleHiddenFiles()` with proper state management
- ✅ **Visual Feedback**: Dynamic button icons and tooltips based on visibility state
- ✅ **Special Icons**: Dot files show as ⚙️ (config), hidden directories as 📂

#### Feature 2: File Content Rendering Enhancement
- ✅ **Backend Logic**: Enhanced `get_file_category()` and `_is_text_file()` methods
- ✅ **Dot File Detection**: Files starting with `.` (no extension) treated as text
- ✅ **Log File Support**: `.log` files now properly detected and rendered as text
- ✅ **Frontend Rendering**: Force plain text rendering for both file types
- ✅ **API Integration**: Structured JSON responses for all supported file types

**Technical Implementation**:
```python
# Backend file type detection
if filename.startswith('.') and extension == '':
    return "text"  # Dot files as text
if extension == '.log':
    return "text"  # Log files as text
```

```javascript
// Frontend forced rendering
if ((filename.startsWith('.') && extension === '') || extension === '.log') {
    this.renderPlainText(data.content);
}
```

**Validation Results**:
- ✅ Hidden files API: `include_hidden=true` returns 6 hidden items, `false` returns 0
- ✅ Dot files rendering: `.testconfig` served as structured JSON with text content
- ✅ Log files rendering: `test.log` properly displays as readable plain text
- ✅ Toggle functionality: Button state sync between frontend and backend

## 🎨 Professional Branding Implementation - Afternoon Session

### VeriDoc Logo Integration
**Complete brand identity implementation across application and documentation**:

#### Logo Preparation & Optimization
- ✅ **Transparent Background**: Removed light gray background for seamless integration
- ✅ **Dark Theme Compatibility**: Inverted colors to white for dark theme visibility
- ✅ **Dual Variants**: Created white logo (web UI) and dark logo (documentation)
- ✅ **Whitespace Optimization**: Cropped from 1024x1024 to 808x392 (60% size reduction)

#### Web Interface Integration
- ✅ **Header Enhancement**: Replaced 📁 emoji with professional VeriDoc logo
- ✅ **Clean Design**: Removed header title and subtitle for minimal aesthetic
- ✅ **Optimal Sizing**: 80px logo with proper alignment to FILES panel
- ✅ **Static Serving**: Configured `/static/logo.png` via existing mount point

#### Documentation Enhancement
- ✅ **README.md**: Centered logo with professional badges (MIT, Python 3.8+, FastAPI)
- ✅ **Architecture Docs**: Added logo to technical documentation for brand consistency
- ✅ **Project Statement**: Enhanced project overview with visual branding

**CSS Implementation**:
```css
.header-logo {
    width: 80px;
    height: 80px;
    object-fit: contain;
}
.header-left {
    margin-left: var(--spacing-xs); /* Align with FILES panel */
}
```

**File Organization**:
- `veridoc/frontend/logo.png` - White logo for dark theme web interface
- `logo-dark.png` - Dark logo for white background documentation

## 🔧 Technical Improvements

### Backend Enhancements
- **FileHandler.py**: Enhanced file type detection with dot file and log file support
- **Server.py**: Streamlined static file serving (removed custom logo route)
- **Text Detection**: Comprehensive `_is_text_file()` method improvements

### Frontend Enhancements
- **File Tree Component**: Added hidden file toggle with state management
- **Content Viewer**: Force plain text rendering for special file types
- **Header Design**: Clean minimal layout with professional logo branding
- **Event Handling**: Proper button state sync and user feedback

### Documentation Updates
- **README.md**: Professional presentation with centered logo and badges
