Struct CollateralCurve 

pub struct CollateralCurve {
    pub atom: usize,
    pub axis: usize,
    pub others: Vec<usize>,
    pub manifold: CollateralArm,
    pub flat: CollateralArm,
    pub manifold_is_cleaner: bool,
}

The on-manifold-vs-flat collateral-damage comparison for one target atom (gam#2234 E2 thesis, measured intrinsically — no model surgery, no outer-fit convergence in the loop). The two arms move the SAME per-row ambient energy: the flat arm applies it along a single fixed decoder direction (the flat-SAE x' = x + α·w baseline), the manifold arm applies the chart-coordinate group action x' = x + a·(Φ_k(t⊕δ) − Φ_k(t))·B_k, which rotates with each row’s coordinate to stay on the atom’s decoded image. The thesis: at matched per-row norm the manifold arm spends strictly less collateral per unit on-target effect — curved features are the right control knobs.

Fields

atom: usize

The steered (target) atom.

axis: usize

The target atom’s latent axis the dose is applied along.

others: Vec<usize>

The atoms collateral is measured against (typically every j ≠ atom).

manifold: CollateralArm

The on-manifold group-action arm.

flat: CollateralArm

The matched-per-row-norm fixed-direction (flat-SAE) control arm.

manifold_is_cleaner: bool

true when the on-manifold arm spends strictly less collateral per unit on-target effect than the flat arm (manifold.efficiency < flat.efficiency), with both efficiencies finite — the E2 dominance verdict, decided structurally in the SAE’s own representation.
