uname: DragonFly dfbsd 6.5-DEVELOPMENT #0: Thu Jul  2 06:02:54 UTC 2026  x86_64 (X86_64_GENERIC, INVARIANTS kernel)
cc: DragonFly cc 8.3
netgraph7: NOT in kernel; built+loaded as modules:
  /usr/obj/usr/src/sys/netgraph7/netgraph/netgraph.ko
  /usr/obj/usr/src/sys/netgraph7/socket/ng_socket.ko
  /usr/src/sys/netgraph7/bluetooth/bluetooth/ng_bluetooth.ko
  /usr/src/sys/netgraph7/bluetooth/hci/ng_hci.ko
sysctl net.graph.maxalloc: 4096
NOTE: standalone module builds do NOT define INVARIANTS (no kernel objdir),
matching production (non-INVARIANTS) module semantics for the
#ifdef INVARIANTS code in ng_*_rehash (DF-3514).
NOTE: guest-local measurement scaffolding: NGM_HCI_NODE_INIT bdaddr gate
bypassed in the guest's copy of ng_hci_main.c (required because DF-3515
wedges the HCI command-complete handshake). Workspace sys/ untouched.
