Ember playbook: the AMD watts source. The script samples the installed app's /api/state power_w for the AMD card every 10 s (a GET), counts the engine's own AMD watts, prints a fallback ladder (median per step, with the step's MH/s and MH/W) when the engine's AMD progress carries no watts, and names the source it used

# the AMD watts source (coordinator, 6 October 2026 16:00Z): the 3.0 coordinator's job read ZERO watts for the 9070 XT
# from igneum-gpu-telemetry.exe while the installed app had read 198.9 W the day before. The tune engine samples its
# own helper; this script also samples the installed app's /api/state power_w for the AMD card every 10 s (a GET,
# never a write) and, when the engine's AMD progress lines carry no watts, prints a fallback ladder from those
# samples (median per step) and names the source it used
