Enum GutterSpec 

pub enum GutterSpec {
    Text(String),
    Bar(f64),
    Spark(f64),
    Labeled {
        name: String,
        value: String,
    },
}

One published gutter-cell value. The display consumes this via the phase render handle; None in the activity’s slot means “derive automatically”.

Variants

Text(String)

Pre-rendered layout text, placed in the cell verbatim (truncated to the cell width by the display).

Bar(f64)

Completion fraction 0..=1 → house braille bar.

Spark(f64)

One trend sample → sparkline ring + current-value label.

Labeled

A key metric: label and value rendered on opposite sides of the cell. Declared as gutter: { final: { name: "recall", value: "{recall}" } }. The pair is explicit rather than split out of one string because the two orders both occur in practice (recall 96% vs ≈900/s units), so no splitting rule can infer which token is the value.

Fields

name: String

value: String
