Every couple of years, someone starts down this line of thinking, and pretty quickly ends up deciding that every deity, powered being, and generally likable character in their fandoms would know about the PPC, and probably also be OOC resistant and and and.
And then someone (not usually me, which clearly indicates there's something wrong with the universe) comes along and points out that 1/ that'll make for really boring missions, 2/ that'll require every writer to be aware of that, 3/ that'll cause calamity if/when they decide to visit HQ, 4/ shouldn't that be kept for really special characters, and 5/... well, there's probably a 5, and maybe more than that, too.
Personally, I'm convinced by reason 1 alone: every mission in that continuum would be either rendered unnecessary (Character X knows about the badfic, and being nice, will deal with it) or ridiculously hazardous (Character Y knows about the badfic, and being nasty, will aid it). But throw in on top of that the fact that the canon doesn't notice badfic effects - otherwise every mission would consist of every single canon fighting against the effect, and running off the moment they're out of the plot. Which they don't. They accept the intrusion as 'part of the world' - because at the time, it is.
So yeah, Character Z may well be able to see everything ever - but since she'll register Mary-Sue Z-Prime as being supposed to be there, that doesn't help any, and since she'll be subject to the same canon-cloaking as every other canon character, she won't notice the agents, either.
And then the badfic will be dealt with, and everything will revert, as it always has. ^_^

(My favourite take on this, for the record, is the idea that Sherlock Holmes independently deduces the existence of the PPC... every single time he encounters it. Because of course he does)
