Msg from slack:

@SFBayLaser @cerati Thanks to your helps I was able to run some test in v10_20_03.
Where I was also facing the jsonnet loading issue like you did.
I tried to fix it yesterday and made another PR to wire-cell:
#471

But I think I need a bit more work to claim finishe.
BTW, yesterday's run was on a sbnd machine (where I have more readily setup):
/exp/sbnd/app/users/yuhw/wcdev-icarus

the log is small enough so I pushed it to github:
https://github.com/HaiwangYu/wcdev-icarus/blob/main/run-20260507-01/detsim.log
