Struct TruingEnvironment 

pub struct TruingEnvironment {
    pub wind: WindConditions,
    pub twist: Option<TruingTwist>,
    pub earth: Option<TruingEarthFrame>,
}

Optional physics the truing forward model can include (MBA-1392).

TruingEnvironment::default() IS the historical truing forward model: calm air, no spin drift, no Coriolis — the state every truing solve hardcoded before MBA-1392, and therefore what every drop-only caller keeps passing. Each field is opt-in and is only enabled when the data that makes it meaningful is actually present; an absent field leaves the corresponding engine flag OFF rather than substituting a guess, so whatever that effect contributes stays absorbed into the fitted quantity. Callers that fit from a lateral observation are expected to say which effects they could not subtract.

Fields

wind: WindConditions

Wind during the observed shots. The default (calm) reproduces the WindConditions::default() that the truing solves have always hardcoded.

twist: Option<TruingTwist>

Barrel twist; Some enables gyroscopic spin drift on the truing solves.

earth: Option<TruingEarthFrame>

Latitude + shot azimuth; Some enables Coriolis on the truing solves.
