Lower bounds from sublinear joint aggregate state #

The graph-ordering coefficient transfers using only the cardinality of a joint factorization. The number of special gates is unrestricted and all gates are counted.

Every dense rectangle-free mixed circuit admits the finite slice estimate. The budget counts the joint final-state guess and its independent accumulator.
