tmd process constantly at 99%

I've noticed my battery is constantly driving down very quickly. I have wifi fully disabled (on the Kindle OS, then I boot framework-less and have it disabled). In a reading sitting lasting about 20 minutes, it used 10% of the battery.

When I ssh in, I can see this process chomping at the cpu: tmd.

I've no clue what it is (though Claude says it's Amazon's todo list, but apparently koreader is supposed to stop it), and when I kill it, things go back to normal.

Any idea if this is normal, and any suggestions on keeping this little s*#t dead?
