Probability-weighted transfer is a different exact proxy

This extends the supplied multi-cell calibration in Hawk02-B CheungHawk02B. A proposed greybody-to-$q_j$ map must still be stated and justified. At $q_j=0$ for every $j$, the code is released, not retained. Entropy turnover alone does not prove that a particular process retains the code; a retaining comparison must be constructed separately.
