The restored polynomial value has one fixed finite loss. Compact local jet ranges suffice: a fixed cutoff removes the irrelevant values away from the outer atlas supports before applying the restoration estimate.

    Fixed local low-jet bounds give a global bound on the actual restored polynomial value. Its scale loss is the maximum of the chartwise losses.

    One profile controls every derivative order, before the actual map and scales are chosen.
