Struct CaptureElision 

pub struct CaptureElision {
    pub dropped_lines: usize,
    pub kept_head_lines: usize,
}

What a step’s captured output lost to the head-plus-tail bound (docs/spec/actions.md’s “Capture”): two counts and no mark.

The mark that draws the gap is the consumer’s, chosen from its live glyph set at render time, so an ascii reader gets an ascii mark; this is the same split ADR 0010 makes between a provenance state and the glyph that renders it. Writing a formatted line into StepResult::output instead would leave the consumer string-matching its own quotation of another program’s screen, which a step printing that same text defeats.

Fields

dropped_lines: usize

How many lines the bound dropped.

kept_head_lines: usize

How many of StepResult::output’s own lines precede the gap, so a renderer draws its mark after that many lines and before the kept tail.
