# Implementation Report

I have completed the requested features and optimizations for the blog system.

## 1. Frontend UI Consistency
- **Visual Style**: Aligned the Admin Dashboard with the "Artistic" dark glassmorphism style from `UI2.html`.
- **Typography**: Applied `Playfair Display` for headings and `Inter` for UI text.
- **Components**: Standardized Sidebar, Header, Tables, and Forms with unified glass effects, colors (`#d4b383` accents), and spacing.

## 2. Backend Code Execution (Sandbox)
- **Runner Engine**: Implemented a `server/runner` package supporting:
  - **Golang**: Compiles and runs `main.go`.
  - **PHP**: Executes `.php` scripts.
  - **Node.js**: Executes `.js` scripts.
  - **Frontend (HTML/Vue/React)**: Configured to return code for client-side rendering (safe handling).
- **Security**:
  - Implemented `context.WithTimeout` (default 5s) to prevent infinite loops.
  - Uses temporary directories for isolation (basic sandbox).
- **API**: Added `POST /api/run` endpoint to execute code snippets.

## 3. Database & RBAC
- **Schema**: Updated `nl_blog.sql` to include `roles`, `permissions`, and `role_permissions` tables.
- **Middleware**: Replaced simple role checks with granular `PermissionMiddleware` (e.g., `users:read`, `posts:create`).
- **Logic**: Implemented full backend logic for:
  - Role management (Create/Edit/Delete/Assign Permissions).
  - Permission verification on all sensitive routes.
  - JWT tokens now carry `RoleID` for efficient validation.

## 4. Backend UI Optimization
- **Unified Theme**: Applied the "Glass" style to all Admin pages (`Users`, `Roles`, `Posts`, `Works`, `Dashboard`).
- **High-Frequency Components**:
  - **Tables**: Transparent backgrounds, hover effects, status badges.
  - **Forms**: Glass-styled inputs, clear validation states, responsive layout.
- **Dashboard**: Optimized stats cards and activity logs to match the new design.

## Next Steps for You
1. **Database Update**: Please execute the updated `nl_blog.sql` (specifically the new `INSERT INTO permissions` statements) to populate the new permission data.
2. **Environment**: Ensure `go`, `php`, and `node` are installed in your system PATH for the code runner to function properly.
