Giorgio Gilestro ab3dc10587 Restructure: descriptive tier and experiment names, paper/manuscript
- paper/pnas -> paper/manuscript (venue-neutral)
- configs/layer1 -> configs/inheritance, src/knowledge -> src/inheritance
  (imported as `inheritance`), make layer1 -> make inheritance; layer2 alias dropped
- inheritance and trained-network bundles named after the manuscript figure
  they feed (fig2_grounding_sweep, figS3_rebaselining, ...), or descriptively
  where they feed none; configs keep their `experiment:` value so parquet
  hashes are unchanged, only output.dir moves
- figure scripts, SI figure sources, notebooks, REPRODUCING.md, README and the
  SI Methods/tables updated; make clean no longer deletes tracked manifests;
  reproduce.sh hashes the s{seed}/ layouts too

# E12 — MODEL SPECIATION / reproductive isolation (the merge-compatibility limit of the sexual society).
# The Bateson-Dobzhansky-Muller construction: an ancestor; two lineages each substitute a DISJOINT set
# of loci (each parent adaptive, neither carrying an incompatibility); a fraction `rho` of cross-lineage
# locus pairs are incompatibilities (penalty `s`) that only bite when a recombinant inherits BOTH derived
# alleles. Sweeping the divergence d (total substitutions) gives the predicted signature
# COMPATIBLE -> OUTBREEDING DEPRESSION -> HYBRID INVIABILITY, arriving earlier the denser the epistasis
# (rho), with the Orr-Turelli snowball (# incompatibilities ~ (d/2)^2, so fitness falls super-linearly).
# A merged model is a single recombinant (F2-like: hybrid breakdown / recombination load), so this maps
# to postzygotic isolation, not F1 vigour. Falsifier: no outbreeding-depression/isolation progression as
# d and rho grow. Pure seeded NumPy on the E7-E11 genotype machinery (bitwise-reproducible).
