# BZZZ Setup API Implementation Summary

## Overview
I have successfully implemented the backend API components for BZZZ's built-in web configuration system by extending the existing HTTP server with setup endpoints that activate when no configuration exists.

## Implementation Details

### 1. SetupManager (`/home/tony/chorus/project-queues/active/BZZZ/api/setup_manager.go`)
- **Purpose**: Central manager for setup operations with integration points to existing systems
- **Key Features**:
  - Configuration requirement detection via `IsSetupRequired()`
  - Comprehensive system detection including hardware, GPU, network, storage, and Docker
  - Repository configuration validation using existing repository factory
  - Configuration validation and saving functionality

#### System Detection Capabilities:
- **Hardware**: OS, architecture, CPU cores, memory detection
- **GPU Detection**: NVIDIA (nvidia-smi), AMD (rocm-smi), Intel integrated graphics
- **Network**: Hostname, interfaces, private IPs, Docker bridge detection
- **Storage**: Disk space analysis for current working directory
- **Docker**: Version detection, Compose availability, Swarm mode status

#### Repository Integration:
- Uses existing `repository.DefaultProviderFactory` for provider creation
- Supports GitHub and Gitea providers with credential validation
- Tests actual repository connectivity during validation

### 2. Extended HTTP Server (`/home/tony/chorus/project-queues/active/BZZZ/api/http_server.go`)
- **Enhanced Constructor**: Now accepts `configPath` parameter for setup integration
- **Conditional Setup Routes**: Setup endpoints only available when `IsSetupRequired()` returns true
- **New Setup API Endpoints**:

#### Setup API Endpoints:
- `GET /api/setup/required` - Check if setup is required
- `GET /api/setup/system` - Perform system detection and return hardware info
- `GET /api/setup/repository/providers` - List supported repository providers
- `POST /api/setup/repository/validate` - Validate repository configuration
- `POST /api/setup/validate` - Validate complete setup configuration
- `POST /api/setup/save` - Save setup configuration to file

#### Enhanced Status Endpoint:
- `GET /api/status` - Now includes `setup_required` flag

### 3. Integration with Existing Systems
- **Config System**: Uses existing `config.LoadConfig()` and `config.SaveConfig()`
- **Repository Factory**: Leverages existing `repository.ProviderFactory` interface
- **HTTP Server**: Extends existing server without breaking changes
- **Main Application**: Updated to pass `configPath` to HTTP server constructor

### 4. Configuration Flow
1. **Detection**: `IsSetupRequired()` checks for existing valid configuration
2. **System Analysis**: Hardware detection provides environment-specific recommendations
3. **Repository Setup**: Validates credentials and connectivity to GitHub/Gitea
4. **Configuration Generation**: Creates complete BZZZ configuration with validated settings
5. **Persistence**: Saves configuration using existing YAML format

## API Usage Examples

### Check Setup Requirement
```bash
curl http://localhost:8080/api/setup/required
# Returns: {"setup_required": true, "timestamp": 1692382800}
```

### System Detection
```bash
curl http://localhost:8080/api/setup/system
# Returns comprehensive system information including GPUs, network, storage
```

### Repository Validation
```bash
curl -X POST http://localhost:8080/api/setup/repository/validate \
  -H "Content-Type: application/json" \
  -d '{
    "provider": "github",
    "access_token": "ghp_...",
    "owner": "myorg",
    "repository": "myrepo"
  }'
```

### Save Configuration
```bash
curl -X POST http://localhost:8080/api/setup/save \
  -H "Content-Type: application/json" \
  -d '{
    "agent_id": "my-agent-001",
    "capabilities": ["general", "reasoning"],
    "models": ["phi3", "llama3.1"],
    "repository": {
      "provider": "github",
      "access_token": "ghp_...",
      "owner": "myorg",
      "repository": "myrepo"
    }
  }'
```

## Key Integration Points

### With Existing Config System:
- Respects existing configuration format and validation
- Uses existing default values and environment variable overrides
- Maintains backward compatibility with current config loading

### With Repository System:
- Uses existing `repository.ProviderFactory` for GitHub/Gitea support
- Validates actual repository connectivity using existing client implementations
- Maintains existing task provider interface compatibility

### With HTTP Server:
- Extends existing API server without breaking changes
- Maintains existing CORS configuration and middleware
- Preserves existing logging and hypercore endpoints

## Security Considerations
- Setup endpoints only available when no valid configuration exists
- Repository credentials validated before storage
- Configuration validation prevents invalid states
- Graceful handling of system detection failures

## Testing and Validation
- Build verification completed successfully
- API endpoint structure validated
- Integration with existing systems verified
- No breaking changes to existing functionality

## Next Steps for Frontend Integration
The API provides comprehensive endpoints for a web-based setup wizard:
1. System detection provides hardware-specific recommendations
2. Repository validation enables real-time credential verification
3. Configuration validation provides immediate feedback
4. Save endpoint completes setup with restart indication

This backend implementation provides a solid foundation for the web configuration UI, integrating seamlessly with existing BZZZ systems while providing the comprehensive setup capabilities needed for initial system configuration.
