isTopicMatched() does not behave correctly for filter that terminates with wildcard /# about paho.mqtt.embedded-c

OASIS spec 3.1.1 section 4.7.1.2 has the following non-normative comment: “sport/#” also matches the singular “sport”, since # includes the parent level.
This is not occurring. Since that is non-normative, and AFAIK Mosquitto and probably many other implementations also do the same, I suggest you also subscribe to '/devices/123-45/commands' if that is what you need. Perhaps you can also publish to '/devices/123-45/commands/cmdname', it's been a while since I played with GCP.

Mosquitto version 1.6.10 running on libmosquitto 1.6.10:

$ mosquitto_sub -t /devices/123-45/commands/# -h mqtt.lab -v &
$ mosquitto_pub -t /devices/123-45/commands/thiscmd -h mqtt.lab -m "This message"
/devices/123-45/commands/thiscmd This message
$ mosquitto_pub -t /devices/123-45/commands -h mqtt.lab -m "This message"
$

Thanks for the quick reply and the reference to the standard.
