# RedFlag (Aggregator)

⚠️ PRIVATE DEVELOPMENT - NOT FOR PUBLIC USE

This is a private development repository for version retention only.

## Status

- **Active Development**: In progress
- **Not Production Ready**: Do not use
- **Breaking Changes Expected**: APIs will change
- **No Support Available**: This is not released software

## What This Is

A self-hosted, cross-platform update management platform built with:

- Go server backend + PostgreSQL
- React web dashboard with TypeScript
- Cross-platform agents (Linux APT/DNF/Docker, Windows Updates/Winget)
- Local CLI tools for agent management
- Update installation system with dependency management
- Refresh token authentication for stable agent identity

## What This Isn't

- Not ready for public use
- Not documented for external users
- Not supported or maintained for others
- Not stable (active development)

## Current Capabilities

### Working Features
- Server backend with REST API
- Cross-platform agent registration and check-in
- Update discovery for APT, DNF, Docker images, Windows Updates, and Winget packages
- Update approval workflow with dependency confirmation
- Web dashboard with agent management and real-time status
- Local CLI tools (--scan, --status, --list-updates, --export, --export=json/csv)
- Update installation system with dry-run dependency checking
- Beautiful terminal output with colors and severity indicators
- Local cache system for offline viewing of scan results
- Refresh token authentication for stable agent identity
- Event-sourced database architecture for scalability

### Known Limitations
- No rate limiting on API endpoints (security improvement needed)
- No real-time WebSocket updates
- Proxmox integration is broken (needs complete rewrite)
- Authentication system works but needs security hardening

## Database Schema

Key Tables:
- `agents` - Registered agents with system metadata and version tracking
- `refresh_tokens` - Long-lived refresh tokens for stable agent identity
- `update_events` - Immutable event storage for update discoveries
- `current_package_state` - Optimized view of current update state
- `agent_commands` - Command queue for agents (scan, install, dry-run)
- `update_logs` - Execution logs with detailed results
- `agent_tags` - Agent tagging/grouping

## Configuration

### Server (.env)
```bash
SERVER_PORT=8080
DATABASE_URL=postgres://aggregator:aggregator@localhost:5432/aggregator?sslmode=disable
JWT_SECRET=change-me-in-production
CHECK_IN_INTERVAL=300    # seconds
OFFLINE_THRESHOLD=600    # seconds
```

### Agent (/etc/aggregator/config.json)
Auto-generated on registration:
```json
{
  "server_url": "http://localhost:8080",
  "agent_id": "uuid",
  "token": "jwt-access-token",
  "refresh_token": "long-lived-refresh-token",
  "check_in_interval": 300
}
```

## Development

### Makefile Commands
```bash
make help           # Show all commands
make db-up          # Start PostgreSQL
make db-down        # Stop PostgreSQL
make server         # Run server (with auto-reload)
make agent          # Run agent
make build-server   # Build server binary
make build-agent    # Build agent binary
make test           # Run tests
make clean          # Clean build artifacts
```

### Running Tests
```bash
cd aggregator-server && go test ./...
cd aggregator-agent && go test ./...
```

## API Usage

### List All Agents
```bash
curl http://localhost:8080/api/v1/agents
```

### Trigger Update Scan
```bash
curl -X POST http://localhost:8080/api/v1/agents/{agent-id}/scan
```

### List All Updates
```bash
# All updates
curl http://localhost:8080/api/v1/updates

# Filter by severity
curl http://localhost:8080/api/v1/updates?severity=critical

# Filter by status
curl http://localhost:8080/api/v1/updates?status=pending
```

### Approve an Update
```bash
curl -X POST http://localhost:8080/api/v1/updates/{update-id}/approve
```

### Token Renewal (Agent Authentication)
```bash
# Exchange refresh token for new access token
curl -X POST http://localhost:8080/api/v1/agents/renew \
  -H "Content-Type: application/json" \
  -d '{
    "agent_id": "uuid",
    "refresh_token": "long-lived-token"
  }'
```

### Dependency Workflow
```bash
# Dry run to check dependencies (automatically triggered by install)
curl -X POST http://localhost:8080/api/v1/updates/{update-id}/approve

# Confirm dependencies and install
curl -X POST http://localhost:8080/api/v1/updates/{update-id}/confirm-dependencies
```

## Security

- Agent Authentication: Refresh token system with 90-day sliding window + 24h access tokens
- SHA-256 token hashing for secure storage
- Pull-based Model: Agents poll server (firewall-friendly)
- Command Validation: Whitelisted commands only
- TLS Required: Production deployments must use HTTPS
- Token Renewal: `/renew` endpoint prevents daily re-registration
