Hum, I disagree. I find it incredibly interesting, if only because there's three likely possibilities. Two of them are interesting, one of them isn't.
One - The only anomalous property is the fact that people who know what they're looking for find it super-anomalous, and that it was designed that way as both proof of concept and bait. They've made something utterly harmless that all our tech and specialists seem to think is Keter-level bad. This means that it's possible to, as the footnotes state, to make something extremely, badly anomalous and we just accept that it's normal, so we don't question. We don't even know to ask. We won't know. And we'll never know if they're about to do it. Or if that it has already been done and we're just slow on the uptake to find this trinket.
Two(my faveorite) - There is something keter-level bad about this. But we are completely unable to see it. We're powerless against it. And we'll never know how badly we've failed.
Three (the Boring Option!) - It's exactly what it says it is, and it's setting off our equipment and screwing with our scientists because if there was NOT an object that would by sheer chance do that, it could potentially mean some incredibly, even-worse-bad metaphysical things regarding the Foundationverse as a whole.
