VecComponents

Source: models/common/VecComponents.py

Decompose a Vec into its three Scalar components.

Wraps the C++ Vec::operator()(int) slot access as a registered Model so component extraction can participate in ComposedModel assemblies. The three output names are user-supplied via the to = 's1 s2 s3' option (resolved positionally as components 0, 1, 2 of the input Vec).

Linear leaf: the forward is to[i] = from(i) and the D-062 pushforward is action_i(V) = V(i) for any incoming Vec tangent \(V\).
