I just spotted a regularity in a 256‑bit hash that should be random—every 64 bits the same pattern repeats. Got a minute to check it?

I noticed that bits 0‑63, 64‑127, 128‑191, 192‑255 all line up identically. The slice is 00110110 01101001 11011010 10011011 repeated. Copy the hex dump and we can plot each 64‑bit block to confirm.
