Torn strip and photograph album

For a classical message $L$, more photographs can reduce $H(L\mid Y_{\le k})$, even though the complete album entropy $H(Y_{\le k})$ cannot decrease.

For an unknown quantum strip, photographs are measurement outcomes, not quantum fragments. A Page turnover belongs to the coherently retained quantum fragments in the stated model. It is not a turnover of the append-only album, and the album does not acquire the original reference entanglement after the last photograph.
