# Data Model: Fix UI Styling, WebSocket Port Mismatch, and URL Validation

## Entities

### ServiceConnection
Represents the configuration for an external service.

| Field | Type | Description | Validation |
|-------|------|-------------|------------|
| `base_url` | `AnyHttpUrl` | The base URL of the service. | Normalized to include `/api/v1` if missing. |
| `name` | `string` | Friendly name for the connection. | Required. |
| `status` | `string` | Connection status (connected, failed, etc.). | Read-only. |

### TaskLogMessage
The structure of messages sent over the WebSocket for real-time logs.

| Field | Type | Description |
|-------|------|-------------|
| `task_id` | `string` | Unique identifier for the task. |
| `message` | `string` | The log message text. |
| `timestamp` | `datetime` | When the log was generated. |
| `level` | `string` | Log level (INFO, ERROR, etc.). |

## State Transitions

### Connection Validation
1. User inputs `base_url`.
2. System validates URL format.
3. System checks for `/api/v1` suffix.
4. If missing, system appends `/api/v1`.
5. System attempts connection and updates `status`.
