HO-013 Cell-1 n4-off arm tau2 full-26 (reasoning OFF, MTP n_max=4) on the v0.6.10 fork/Vulkan stack (2586f6edd). Counter interpolated from 33.772208 to 33.829381 kWh across the n4 tau2 window 07:29:04.077901-07:53:21.027156Z on 2026-08-23 (1456.9s, n_power=144). 17/26 tasks passed, so wh_per_task uses 26 and pence_per_correct uses 17 correct tasks. Single isolated active band (idle floor 10.1W), no contention. cfg-0160 / build 2586f6edd Vulkan/RADV on v0.6.10. Compare arms already wired: eng-0235 (plain tau2 76.96 Wh), eng-0236 (n2 tau2 53.10 Wh). Capability comparison only; no production/throughput claim. Window within HA retention (~10d; run ended 07:53Z, joined same day).
Wh, never joules — read as a cumulative-counter difference across the window; delta over the idle baseline is the only figure that means anything
