Let $n>0$ , let $x$ be an integer input of length $n$ , and fix a coloring of width $\lfloor\log_2 n\rfloor+1$ . Suppose memory at free base $f$ satisfies the encoded color pipeline's stored-data contract for strictly increasing normalized lists $A,B,C$ . Let $q$ be the pipeline's finish address, and let $C(n,U)$ be the cell requirement of the encoded color resource record for an arbitrary natural parameter $U$ .

The reporting base, defined as $q+8$ , satisfies

q+8\le f+C(n,U).

No additional bound on the input values is assumed in this address comparison.

This locates the start of reporting within the common source allocation and allows later reporting resources to be attached to the stored pipeline data.
