Uniqueness of the higher-dimensional radial deformation
Determine whether the higher-dimensional radial deformation of conformal partial waves, including its flow operator, deformed Casimir, and inner product, is uniquely fixed by crossing covariance, sector closure, and spectral consistency.

Unlike in the torus construction, it is not known whether the higher-dimensional deformation is unique.
