Direct graded non-feedback and quotient response

The reported cubic slots $Kch,\bar{c}ch,c^{\ast }cc,hhh$ have three field slots; spectator vectors representing an epsilon tensor are not fields. The predecessor attributes a slot-count check on 821 even coordinates and the odd terms to 1_1c.py; that archive is not newly inspected.

This theorem concerns direct graded re-expansion, not Wick contraction, expansion around a nonzero background, or an unspecified changed identity response. Such operations need their own maps. A formal zero projection does not establish the validity of a strictly four-dimensional Schouten quotient in DRED.
