## Alignment transform

- Scale recovered: `0.925472` (deviation from metric: 0.0745)
- Rotation angle undone: `2.613` deg
- Translation norm: `0.0462` m
- ICP iterations: `32`, final RMSE `0.006166` m

_The rotation angle is the magnitude of the alignment rotation the solver had to
apply; the reconstruction frame is arbitrary, so it is not an error against a
reference. For symmetric objects the transform is defined only up to the object's
symmetry group._
