Struct ScalingReport 

pub struct ScalingReport {
    pub samples: Vec<(usize, usize)>,
    pub per_item: f64,
    pub fixed_overhead: f64,
    pub is_constant: bool,
}

How a program’s output token cost grows with result size — the curve that matters at agent scale, not a single-size sample. Fit from samples at several sizes: a marginal per_item cost (slope) and a fixed_overhead (intercept).

Fields

samples: Vec<(usize, usize)>

The (size, output_tokens) samples measured.

per_item: f64

Marginal tokens per additional item (least-squares slope); ~0 means O(1).

fixed_overhead: f64

Fixed output overhead independent of size (intercept; header/framing).

is_constant: bool

True iff output is effectively constant-size (per_item below ~0.5 tok/item).
