Unfinished supported tensor sum

supported tensor sum{ The lower coefficients ${c_{\zeta ,1}}^{I,J}$ and their combined kinetic contractions still have to be evaluated from (eq:normal-extraction). Formula (eq:plateau-inventory) is an exhaustive local recipe, not a proof of cancellation or nonvanishing of the general supported plateau coefficient.

The new complete-family failure theorem uses the evaluated isolated positive-placement coefficient instead, and does not silently replace this remaining task.}
