# Proposal: Add Admin Room Management

## Why

Currently, rooms can only be soft-deleted (archived) and non-admin users can still see archived rooms when filtering. This creates two issues:

1. **No permanent deletion**: Archived rooms remain in the database indefinitely, and there's no way to completely remove sensitive or test data.
2. **Archived rooms visible to all**: Non-admin users can view archived rooms by changing the status filter, which may expose historical data that should be hidden from general users.

## What Changes

### 1. Admin-Only Permanent Room Deletion
- Add new endpoint `DELETE /api/rooms/{room_id}/permanent`
- Only system administrator (ymirliu@panjit.com.tw) can execute
- Cascading hard delete of all related data (members, messages, files, reports)
- Clean up MinIO storage for associated files
- Broadcast WebSocket disconnect to active connections

### 2. Hide Archived Rooms from Non-Admin Users
- Modify room listing to exclude ARCHIVED status for non-admin users
- Even "All Status" filter will not show archived rooms for regular users
- Admin users retain full visibility of all room statuses
- Remove "Archived" option from frontend status filter for non-admin users

## Out of Scope
- Batch deletion of multiple rooms
- Scheduled auto-deletion of old archived rooms
- Restore deleted rooms from backup
