# Ember: the SHIPPED app tunes itself (6 October 2026). Unelevated, no kit, no second engine, no --stop-miners:
# the installed app (0.3.14 or later: Ember Tune, the Power Helper task, /api/tune/goal, the climb) runs one tune
# per card through the registered task (no prompt) while it mines. This script only asks and watches:
# POST api/tune/goal (the climb on, balanced) and POST api/sweep/start per card, then reads api/state and the app's
# own log for the TUNE rows. It never quits, pauses or resumes the installed app (the 5 October rule) and never
# touches the cards itself. At the end the climb switch goes back to what it was.
# Order: the AMD card's ladder first (the ADLX apply-on-ack fix, bd7fcf4), then each NVIDIA card's climb.
