+# POPULUS — paired-visibility battery checkpoints
+
+Final checkpoints for **"What You Can't See Is What You Learn: Restricted
+Evidence Visibility Favors Compositional Generalization in Shared-Genome
+Language-Model Societies"** (Narcis Marincat, 2026; arXiv link to follow).
+
+Twenty-two files: nineteen society finals (`run3v_F_{P|G}_m<init>_o<order>_ckpt_final.pt`
+— P = restricted visibility, G = global visibility; the twentieth, P
+init 202 / order 952, is marooned on an unreachable provider instance and
+disclosed in the paper) and three staged centralized comparators
+(`posctl_F_s93*_ckpt_final.pt`).
+
+Each checkpoint contains the trainable bridge parameters, the shared rank-8
+LoRA, and optimizer/RNG state for bit-exact resume, over a frozen
+Qwen2.5-0.5B-Instruct backbone (not included; loaded from its own
+distribution). Evaluation code, result records, preregistration, and the
+incident ledger: https://github.com/tokenosopher/populus-evidence-partitioning
