Struct CollateralPoint 

pub struct CollateralPoint {
    pub dose: f64,
    pub on_target_effect: f64,
    pub collateral: f64,
    pub cross_feature: f64,
}

One dose sample on a collateral-damage curve (gam#2234 E2, the intrinsic Rust-owned counterpart of the model-in-the-loop KL frontier): the on-target effect and the off-target collateral of a single steering intervention, measured in the fitted dictionary’s own representation, with no LLM in the loop.

Fields

dose: f64

The chart-coordinate dose applied to the target atom’s steered axis (radians / fraction-of-period, per the atom’s manifold).

on_target_effect: f64

RMS-over-rows on-target effect: ‖proj_{T_k} Δ‖, the energy the intervention deposits into the TARGET atom’s own local decode-tangent frame T_k = ∂g_k/∂t at each row’s fitted operating point. This is the intended landing — how loudly the knob turned the feature it names.

collateral: f64

RMS-over-rows collateral: ‖Δ − proj_{T_k} Δ‖, the energy the SAME intervention deposits OUTSIDE the target atom’s own local frame — the total damage. The on-manifold move is a chord of atom k’s decoder curve, so its off-target component is only the second-order sagitta (≈ 0, growing with dose-curvature); a fixed flat direction is off the rotating target frame at most rows, so its off-target energy is immediate. This is the direct generalization of the single-move SteerPlan::off_manifold_norm guard to a swept intervention.

cross_feature: f64

RMS-over-rows CROSS-FEATURE leakage: sqrt(Σ_{j∈others} ‖proj_{T_j} Δ‖²), the part of the move that lands on OTHER named atoms’ frames — the interpretable “steering feature k spuriously moved feature j” damage, a component of the total collateral.
