Problem

nerve dev starts the kernel but the worker process exits immediately with code null (killed by signal). Same workspace works fine with nerve start -d (daemon mode).

Reproduce

cd ~/.uncaged-nerve
nerve dev

Output:

✅ Nerve starting — 2 sense(s), 1 group(s)
   group "system": cpu-usage, linux-system-health
[daemon-ipc] listening on ...
[kernel] worker for group "system" exited with code null

nerve start -d with the same config runs fine and collects data.

Expected

Worker should stay alive in foreground mode just like daemon mode.

Notes

  • code null means killed by signal
  • Likely signal handling difference between foreground and daemon mode
