  ● The VRR power run is complete. The email (VRR power results plus the Bluetooth correction) went to kw@linux.com at 03:06, and msmtp returned 250. 107 runs its default kernel, linux-omarchy-bore.

  Result (RAPL psys, mean of 3 windows per kernel and case; boot order ptl, base, bore, bore, base, ptl, ptl, base, bore):

  - Panel off and idle: the three kernels are equal within 0.02 W. The CPU package power is also equal in every case.
  - First run's high idle windows: they did not come back. All 18 idle windows of this run measure 6.55 to 6.59 W. Those high windows were a change over time, not a kernel effect.
  - VRR on: it saves 0.53 W in video on our kernels and nothing at idle.
  - VRR on linux-ptl: the video does not play correctly. Its lower power comes with dropped frames, because that kernel has neither 0443 nor 0444.
  - Hang: the reboot from linux-ptl 7.1.11 at 02:24 did not complete. That boot's journal ends in a normal shutdown, and the boot loader did not run until your power cycle.
