What I mean is that, for that kind of "alarm system" we would need a sort of "satellite constelation" around our solar system of a kind similar to the satellite constellation that we have around Earth, and such endeavor would only be feasible for a TL10+ civilization

You don't really need a major constellation. Two, with sufficient separation, will have line of sight to most of the solar system. Three, effectively everything. More will increase the odds that one happens to be looking in the right direction at any given moment, of course.

An object this size, without some magic stealth we can't account for (and thus renders asking the question pointless), will be spotted in short order once it is in line of sight of anything actually looking.

That's the thing, having enough satellites looking at the right direction. That's why a small handful could find it, but that's not a given.
