+## These consoles hang off an 8-port WCH CH34x adapter whose 8 ports share ONE
+## USB interface (…:2:1.0), so ID_PATH / ID_SERIAL / ID_USB_INTERFACE_NUM are
+## identical for every port and can't select one. The stable per-port key is the
+## parent's sysfs attr `port_number` (== the /dev/serial/by-path -portN index),
+## reached with labgrid's `@` ancestor-match (udev.py match_single checks sysfs
+## attributes). ID_PATH scopes to this adapter; @port_number picks the channel.
+## (labgrid renders this file with jinja2; '#' is a statement, '##' a comment.)
