+
+Per-weight **contrastive style-Fisher ratios** for style-aware 31B merges (J-line / target-side style mask).
+
+Each subfolder holds a `style_ratio.pt` (bf16, target LM-linear keys only: q/k/v/o_proj + mlp
+gate/up/down in `language_model.layers.*`) + `ratio_layer_summary.json`.
+
+`r_w = F_A / (F_A + F_B)`, where `F_M = relu(Fisher(M under S+ style prompt) - Fisher(M under S-))`
+over matched generations. `r_w > 0.5` => weight carries more good-style signal in model A;
+neutral 0.5 below a combined-Fisher floor. Consumed by `04_merge_style.py` (trim-then-weight TIES).
+
+Pipeline: `instruct_mask/style_mask_j1/`. Public so multiple ~35GB masks fit without private-storage limits.
