Scope and debugging of the proposed programme

The purpose of this manuscript is to make a categorical benchmark operational without confusing three different kinds of conclusion:

The proposed programme is completed at the finite benchmark level. A literal operational realization of the full Family 069 functor is not claimed.

The distinctions between an implemented decoder, an optimal decoder, a finite algebra task, a subsystem task, and a physical interpretation are emphasized in the supplied Cheung records Cheung280C,Cheung290A,Cheung265B,CheungEn02B, CheungEn02C,CheungEn05C. Every finite interface used in the proofs below is defined and proved locally. Those manuscripts provide attribution and comparisons, not unchecked theorem premises.
