Manuscript revision and pending experiment work, snapshot before restructuring

Clarity pass over the main text (36-item audit), Discussion rewrite and cut,
acknowledgements, Souly et al. as ref 62, lettered SI panels, model section
moved under Results; plus the untracked curriculum/society/compose/smol
configs, runners, figures, stats and tests that the SI already cites.

+# Calibration stage A, second pass (prereg §4 amendments, 2026-09-07): the first pass left only six
+# families in band. Changes, each recorded in the prereg: founder budget 600 -> 1200 x 3 (uniform);
+# roman / binary / prime prompt spaces enlarged; three new learnable candidates (wordlen,
+# lettercount, sumeven); the specialist UPPER bound relaxed 0.90 -> 1.00 (the headroom argument it
+# encoded concerns fusion composing to a ceiling, not transmission/assembly). Families whose
+# specialist scored <= 0.20 in pass 1 (sortletters, caesar, progression) are not re-trained.
