Root cause: agent-health.service runs Type=oneshot with the default
KillMode=control-group. restart_browser() spawned the replacement
chromium with nohup under the service, so systemd SIGKILLed it the
moment the service exited. Every 5-min tick: FAIL -> restart ->
RECOVERED -> SIGKILL at teardown. opm and pip were permanently dark
and dm.py read masked it (empty output, exit 0).
Fix: launch replacements via systemd-run --user --scope (backgrounded)
so the browser lives in a transient scope outside the service cgroup
and survives teardown. setsid does NOT escape either. Note:
systemd-run --scope waits for the scope even with --no-block
(verified 2026-10-03), hence the backgrounding. Same fix in
chromebox-watchdog.sh (timers currently off).
dm.py: dm_read() now uses run_full() and prints a WARNING to stderr
with rc + last error line instead of failing silently on empty reads.

New bin/netvm-registry.py parses NODES.md (node -> cdp_port); every
consumer reads from it instead of hardcoding:
- onboard-driver.py: CDP_PORTS dict -> registry lookup (new nodes work)
- muse-signin.py: hardcoded 9410 -> --node/--cdp-port args
- muse-chat-api.py: hardcoded ACCOUNTS -> registry-built
- agent-health.sh: hardcoded muse/pip blocks -> loop over all active
nodes (646 and opm now get health coverage too)
NODES.md: record opm node (9440).
