clock lock [by the CARD]: ON-BY-CARD evidence: the card was AT REST for the whole sample (utilization.gpu read 0 % on all 12 reads) and clocks.sm never left the lock's floor: min 1192 MHz, max 1522 MHz, against a declared floor of 1200 MHz and the driver's 25 MHz quantization tolerance (the driver snaps 1200 to 1192 on this board, measured 2026-09-21T23:13Z). Unlocked and at rest this board reads 232 MHz or less (232 MHz at 17:30Z, 180 MHz at 18:11Z), so a resting card pinned at the floor is the lock holding it there. clocks.max.sm reads 3090 MHz, which is this board's own unlocked maximum with OR without the lock and is therefore not part of this verdict. the unit ai-perf.service reads active — NOT EVIDENCE: it is Type=oneshot, so it reads 'active (exited)' for the whole uptime whether or not 'nvidia-smi -rgc' has released the lock since. On 2026-09-21 a receipt that trusted it published 'ran with the lock ACTIVE' beside clocks that proved otherwise.
