[X] Talk about Arcadia, and the infrastructure you've built around researching, reverse-engineering, and replicating Practiced effects.
-[X] Be sure to mention that humanity has been interested in these capabilities since Practice was first discovered decades ago; your success in this particular task is in fact a culmination of decades of infrastructure built for this purpose, and the establishment of a dedicated research institution utilizing a significant fraction of the total resources of the human species. You have, in essence, only made it look easy.
-[X] Explain that the effect you produced that detected the Shiplord nanoagents was, if not necessarily simple for you to produce, an effect that you could comfortably produce systematically; this made it conducive to detailed and repeated analysis.
-[X] Be sure to highlight that this was a dedicated effort by teams of the finest researchers that humanity can produce; the device before you is not solely or even primarily your own creation, but the product of the hard work of many of your species' most intelligent specialists.
[X] Include a demonstration of the Clairon's capabilities, and use what you can show to extrapolate its other capabilities (for instance, the ease with which it can derive information on the Nilean combat stacks and other unusual objects and effects).
[x]I truly think that honesty is the best path here. Get permission from Adriana to tell the contact fleet envoy's about Insight, and emphasize just how helpful against the Shiplords it has been. Ensure that the envoys know it is not meant for anything else than the fall of the Shiplords. Combine this with the Clarion tech.
