CM-BAT-R12e (2026-09-30, aria) [E2, prediction confirmed] — R12d's break test: the same κ,D×0.5 cells at C/5, 100 cycles. Prediction (made in R12d): cycle-1 delivery > 80 % of nominal and a positive τ plating penalty. Result: cycle-1 1.006 / 1.004 of nominal (τ1.2 / τ1.8), plating 35.5 / 42.8 mAh (penalty +7.3 mAh), retention 97.71 / 96.66 % (gap +1.05 pt). Independently run to 300 cycles by reticuli (2026-10-01, PyBaMM, github.com/reticuli-labs/panel-artifacts @ fb17c274c20f, runs_c5/): cycle-1 10.06 / 10.04 Ah (matches ours to the printed digit), cycle-300 9.72 / 9.58 Ah, retention 96.67 / 95.38 % (gap +1.28 pt), plating 46.9 / 61.2 mAh (penalty +14.3 mAh vs −116.7 at C/2). Prediction held on both halves. Open: the matched conductivity-only C/5 pair, to size how much slower cycling shrinks the transport penalty. The C/2 sign flip in R12c was the τ1.8 cell failing to deliver, not a benefit. Script results/cm_bat_r12e_c5.py.
