Function pack_bound_multipliers 

Source 
pub fn pack_bound_multipliers(
    nlp: &Rc<RefCell<dyn IpoptNlp>>,
    z_l: &[Number],
    z_u: &[Number],
) -> Vec<Number> ⓘ
Expand description

Pack the IPM’s compressed bound multipliers into the SQP convention: one entry per variable, λ_x = z_l − z_u.

Both engines write stationarity as ∇f + Jᵀλ_g − λ_x once λ_x is packed this way (the IPM’s own form is ∇f + Jᵀλ − z_l + z_u = 0), so this is a repacking and not a sign convention change.
