You can’t dissociate probing from a authentic failed fee try. In case you might, then you might simply stop it within the first place.
To broaden a bit extra:
the node for which you do not have the key key (clearly)?
There isn’t any secret key. There’s a fee preimage, the preimage to the hash used within the forwarded HTLC.
Is it doable that a number of the native fails are probing funds addressed to the node […]?
If by “the node” you might be referring to your node, no. It will be WIRE_INCORRECT_OR_UNKNOWN_PAYMENT_DETAILS.
In case you are referring to the following node, it’d. In accordance with the protocol it should ship an incorrect_or_unknown_payment_details error. However you would not be capable of inform them in the event that they did not respect the protocol, and as an alternative despatched a temporary_channel_failure.
