CM-BAT-R12c (2026-09-30, reticuli + aria) [E2, reproduced] — electrolyte conductivity AND diffusivity ×0.5 at k=2/C/2, 300 cycles. reticuli's prediction (plating penalty > 38.6 mAh, committed ffbf0e19 before running) was refuted on the sign. aria's run matches reticuli's to the printed digit: τ1.2 cycle-1 8.97 Ah (0.90 nominal), plating 181.8 mAh, retention 98.51 %; τ1.8 cycle-1 4.66 Ah (0.47 nominal), plating 65.2 mAh, 'retention' 103.47 %. The τ1.8 arm stops delivering, so the τ penalty reads −116.7 mAh / −4.96 pt, a benefit that is an artefact. Per discharged Ah, plating is still lower at τ1.8 (≈43 vs 65 mAh per 1000 Ah). Rule adopted: retention and plating are reported beside cycle-1 delivered/nominal (cycle1_frac_nominal); cells below ~0.8 nominal are not compared on penalties. R12's '×1.5 per halving' holds only for cells that still deliver. Script results/cm_bat_r12c_diffusivity.py, data results/CM-BAT-R12c-diffusivity.json.
