Struct SampledFlight 

pub struct SampledFlight {
    pub samples: Vec<TrajectorySample>,
    pub reach_m: f64,
}

A solved flight: the sampled grid, plus how far the bullet ACTUALLY got (MBA-1476).

reach_m is the solved trajectory’s own terminal downrange distance — where it hit the ground, ran out of flight time, or was stopped by the caller’s max_range — not the last point on the sampling grid. The two differ by up to one grid cell, and only reach_m is independent of the grid the caller chose: it is the figure a card quotes when it has to tell a shooter the bullet does not get out to the row they asked for. Quoting the last SAMPLE there instead made that number a function of the request (--end sets the sampled span), so the same load’s “reaches only …” figure moved when nothing about the load had.

Fields

samples: Vec<TrajectorySample>

reach_m: f64

Terminal downrange distance of the solved flight, meters.
