# Igneum run job (second round, bench only; the first round's packs were refused for a string seed): the read-width experiment on PC 2's RTX 5090 (machine 1ccfe586), 5 October 2026 (docs/plans/read-width.md).
# Published as a plain `run` job (NOT --stop-miners): the installed app keeps every other card mining; this script switches
# off ONLY the NVIDIA card in the app through POST <app.url>api/cards, waits for its worker to stop, runs the fetched
# igneum-worker-cuda.exe (--memprobe, then --bench on every pack of the fetched packs folder), and switches the card back
# on with the settings it had. Every result line starts with RESULT so `node tools/jobs.mjs <job id>` shows them.
