Connection Establishment

sequenceDiagram
    participant C as Client
    participant S as Server
    C->>S: Connect to :50051
    S-->>C: Connection established
    C->>S: GetChassis()
    S-->>C: Chassis data
    Note over C,S: Connection ready for streaming

Bidirectional Streaming Flow

sequenceDiagram
    participant C as Client
    participant S as Server
    C->>S: Open SendCommand stream
    S-->>C: Stream ready
    C->>S: SendCommandRequest (Connect)
    S-->>C: CommandResponse (Success)
    C->>S: SendCommandRequest (GetTasks)
    S-->>C: CommandResponse (TaskCollection)
    C->>S: SendCommandRequest (Heartbeat)
    S-->>C: CommandResponse (Heartbeat)
    Note over C,S: Stream remains open
    C->>S: Close stream
    S-->>C: Stream closed
