# (The vertical claim / Fisher-Muller — the society headline): can an offspring recombined from
# MANY decorrelated parents be fitter than ANY parent? Each parent is a specialist: confident-
# correct (hi) on the loci it has mastered, agnostic (~0.5) elsewhere; which loci each masters comes
# from the exact shared-switch construction, so parent count K_T and decorrelation rho are clean
# knobs. Deployed capability = fitness of the MODE genotype. Compare best single parent vs mean-
# mixture ("model soup", combine-but-don't-recombine) vs sexual recombination (assemble the best
# allele of each locus across all parents). Expect: sexual climbs to the optimum (=L, a genotype NO
# parent had) as K_T grows and rho->0, while best-parent and average plateau far below. Unlike
# biological sex there is no two-parent limit. Falsifier: sexual never exceeds the best parent, or
# averaging matches sexual.

society:
  L: 12            # loci; the optimum (all-correct) has fitness 12 and no parent possesses it
  q: 0.5           # fraction of loci each parent masters (marginal mastery)
  hi: 0.9          # correct-allele prob on a mastered locus (confident expert)
  lo: 0.45         # correct-allele prob on an unmastered locus (agnostic, slightly wrong)

sweep:
  - param: K_T
    values: [1, 2, 3, 5, 8, 12]     # number of parents (unbounded; grows the recombinant reach)
  - param: rho
    values: [0.0, 0.5, 1.0]         # decorrelated -> identical parents (the control)
