paper/response-to-review.md: point-by-point response covering the claim-narrowing revision (interpretation/explanation/prediction ladder, drift/ratchet scoping, merge-operator boundaries, speciation scope block, the claims table, control-theory->framework, the three supporting overstatements) and the new experiments run in answer to the review — full-symmetry alignment, the pre-registered emergent null, LLM-tier speciation, multi-seed replication, and the decisive epistasis-predicts experiment with its control axis and its honestly-failed internal prediction. Two mild push-backs stated; open items listed; invites another iteration. Also fixes the one §4 review point not yet addressed in the text: §11's "unbounded growth of capability" close is rewritten — the architecture removes the STORAGE obstacle to indefinite accumulation; that is bookkeeping, not a demonstration of unbounded capability growth.

The Lamarckian Society — Layer 1 (analytical core)
A parametric population-genetics model of knowledge transmission across generations of
learning agents. Knowledge transmission is modelled literally as a Wright–Fisher
process (not by analogy): a model's knowledge is a distribution p_t over K discrete
items; a fixed true distribution p* has a rare tail; each generational step is
"sample from the parent (drift) + mix in fresh real samples (grounding/immigration) +
refit." Model collapse is the loss of rare alleles under drift.
See paper/blueprint.md (the normative build spec),
paper/the-lamarckian-society-v5.md (the perspective paper), and
paper/results-summary.md (a summary of all results).
Reproduce
Environment is a uv venv built from the committed, hash-pinned uv.lock — that
lockfile is the single source of truth for "it runs" (Layer 1 is pure NumPy/SciPy and
bitwise-reproducible from a seed; no container needed).
# one-time: install uv (https://astral.sh/uv)
curl -LsSf https://astral.sh/uv/install.sh | sh
uv sync # build .venv from uv.lock
make test # correctness + scientific-validation tests (the spine of trust)
make layer1 # run experiments E1–E6
make figures # regenerate figures from committed results
