E6: entropy trajectories and reference information

At $p=1$, pure-input radiation entropy is the same for $\eta =0$ and $\eta =1$, although their optimal recovery errors are $1/2$ and zero. The reference mutual information is one and two bits, respectively. This is an explicit reason to report entropy, classical distinguishability, and referenced recovery separately.

No Page-curve interpretation is assigned to these tables. Fine-grained gravitational entropy calculations address a different construction problem EntropyReview; an entropy trajectory alone does not specify the microscopic channel used here.
