A process crashed on this Omarchy machine and I want to know why.

What systemd-coredump recorded:
  process:  $comm
  PID:      $pid
  binary:   $exe
  signal:   $signal
  time:     $when

Use the diagnose-crash skill: it covers how to investigate, what to report, and
when a crash is worth reporting upstream to Omarchy. If your harness has no skill
mechanism, read the skill files directly and follow them instead:

  $skill
