valid

The set of valid labels in a data framework is the set of modified labels above and including the label containing a feature which is to be recalculated.

Consider the case of a box to which you first add a fillet, then a protrusion feature. For purposes of recalculation, only valid labels of each stage of the construction are used. In recalculating the fillet, these are only those of the box and the fillet, not the protrusion feature which was added afterwards.
