If anyone made a mistake, it was Sanderson, not RJ. - Edit 1

Simpler than this paralis-net-of-the-gaps argument is to say that the paralis-net is, in fact, the entire set of ornaments and, if that's incompatible with Demandred's statements in WH, then it's a continuity problem.
And one that, if it's ever resolved, will likely end up with Demandred's statement edited rather than Rand's.

It is pretty clear from RJ's Cleansing scene that neither Demandred nor Lanfear had encountered the two most striking effects of Cadsuane's ornaments before. RJ was crystal clear in that respect.
What we're left with is that either Sanderson made a mistake when he had Semirhage allude to the paralis net, and again when Lews Therin referred to it, or else the paralis net in it's Age of Legends form did not include those two functions.
The fact that the "paralis net" had an official name at all, makes it more likely that it existed in the Age of Legends, and therefore the logical answer is that Lews Therin and Semirhage's paralis nets served a different purpose to saidin detection and weave unravelling.
It might even be that a paralis net is merely some sort of mounting system for other angreal and ter'angreal to be attached to.
Fact is, RJ stated unambiguously in the case of two seperate Forsaken that Cadsuane's effects were unknown in the Age of Legends. Why would Sanderson know better than him?
