The L4T kernel ships without qmi_wwan/cdc-wdm, and PPP dial-up made KDDI
detach the povo SIM (attach APN was au's; PPP re-activating the default
bearer still detached). Built both modules out of tree from v5.15.148
into ~/infra/qmi_wwan, set the attach APN to povo.jp, and added an NM
connection at metric 1000 so LTE ranks below Ethernet and WiFi.
GNSS autostarts on the modem and gpsd reads /dev/sim7600-gps (udev
symlink on interface 01); no fix yet, tested indoors.
BOM: NMEA is on ttyUSB1 not ttyUSB3, and the data path is QMI, not
RNDIS/PPP.

The original report was written on another host. On this machine the
pcan module (NETDEV_SUPPORT) is built, installed under misc/, and loaded
at boot via /etc/modules; the adapter was not yet plugged in. Adds the
verification and post-kernel-update rebuild steps.

Replaces `type: default` — one value across every document, read by nothing.
Types are now reference, guidelines, plan and report; plans carry status and
updated, reports carry date. Convention documented in project-yukart REPOS.md.
