- 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

# (The dynamic Lamarckian society — the vertical claim, C3): a finite population of agents (genotypes)
|
|
# evolves on a rugged NK fitness landscape that IS reality. The full society composes the four
|
|
# operators the whole study built toward — grounding, directed recombination (sex), quality-diversity
|
|
# selection, and mutation — and a 4-arm ablation shows each is load-bearing. Grounding is made load-
|
|
# bearing via the consensus-conformity (self-consumption) mechanism: selection acts on
|
|
# g*true_fitness + (1-g)*conformity, so at g=0 the society optimises agreement with its own majority
|
|
# rather than reality and drifts to a fit-looking but actually-poor consensus. Expect: FULL climbs to
|
|
# near the global optimum while maintaining diversity longest; NO_GROUNDING collapses to the unfit
|
|
# consensus; NO_SEX plateaus (can't recombine to escape local optima); NO_DIVERSITY (greedy) collapses
|
|
# diversity fast and stalls at a worse local optimum. Falsifier: an ablation matches the full society,
|
|
# or the full society fails to exceed every ablation.
