Enum ScaleOperation 

#[non_exhaustive]
pub enum ScaleOperation {
    WholeDocumentLinearUnits {
        factor: f64,
    },
    RestBindUniformScale {
        source_skin_index: usize,
        source_root_node_index: usize,
        expected_factor: f64,
    },
}

The two distinct scale operations DESIGN.md Appendix D §D.1 defines.

Neither variant infers its factor or applicability from mesh bounds, character height, joint lengths, inverse-bind magnitude, filename, or an asset category. The caller names the operation and declares or accepts the exact factor plan_scale validates.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

WholeDocumentLinearUnits

Whole-document linear-unit conversion: every represented length is converted by the declared finite positive factor.

Fields

factor: f64

Declared finite positive conversion factor q.

RestBindUniformScale

Rest/bind hierarchy reparameterization: removes one compensating inherited scale from a restricted skinned hierarchy.

Both selectors are raw, format-neutral source identity — a source node/skin array index, per DESIGN.md Appendix D §D.7 — not a normalized BoneId or mesh-instance ordinal. plan_scale resolves them through crate::model::SceneAssets::source_skeleton.

Fields

source_skin_index: usize

Stable source-skin-array index selecting the skin whose joints anchor the affected domain.

source_root_node_index: usize

Stable source-node-array index of the scaled ancestor root.

expected_factor: f64

Caller-declared expected common factor s. Planning measures the source’s observed rest-world factor and rejects a mismatch rather than inferring s from geometry.
