mesh-delivery is the delivery's seat and the module holding it, which answers the seat's verbs with tools of the same names. Discovery keyed the seat's verbs and the module's tools in one namespace, so the module's tool took the key and the seat was listed with no verb; and every address with the name resolved to the seat, so neither the seat's verbs nor the module's tools could be called. The keys are apart, and `<node>/<module>.<tool>` reaches the module when the module serves it (novox/hq issue 284).
