Enum Event 

pub enum Event {
    Message(String),
    Detail(String),
    Artifact(Box<dyn Artifact>),
}

Structured output event produced by commands

An Event represents a single piece of output that a command has produced. Events travel from the producer through an async channel to the Presenter, decoupling production from rendering.

Three variants:

• Message — informational text (shown at default verbosity and above).
• Detail — supplementary text (shown only at verbose verbosity).
• Event::Artifact — the primary data a command produces, carried as a trait object that the Presenter can render via Display or Serialize.

The Presenter decides which events to render based on its verbosity setting.
