tau2 airline full-26 (run-0653, wall 6701 s). Energy counter 44.38310 -> 44.66940 kWh = 286.3 Wh total; steady ~154 W throughout (midpoint 22:04Z = 44.52170 kWh cross-checks: 150.9 W first half, 156.6 W second half). Idle floor 10.1 W * 6701 s / 3600 = 18.80 Wh; active 267.5 Wh. Headline Wh-per-correct = active_wh / 21 correct = 12.74 Wh; pence-per-correct = 0.386 p @ 30.3 p/kWh; whole-run cost 8.68 p. baseline_w 10.1 W is the same box-idle-all-empty floor used for eng-0275 (identical aihydra hardware). Power-sensor hourly statistic for the 22:00-23:00 UTC bucket read anomalously low (~17 W mean) against the counter-derived ~154 W — a sensor-reporting gap, not real idle; the cumulative energy counter is authoritative and its steady progression (verified at the midpoint) is used. NOT reasoning-matched to eng-0275: this run used the model's DEFAULT reasoning effort (heavier generation) in the single-slot adaptive-MTP serving config, whereas eng-0275 (UD-Q4_K_XL) used reasoning_effort=low — so the 12.74 vs 9.90 Wh-per-correct gap conflates quant, reasoning depth, and a lower correct count (21 vs 24); a reasoning=low re-run is the matched comparison.
Wh, never joules — read as a cumulative-counter difference across the window; delta over the idle baseline is the only figure that means anything
