Cant expect less.
See? At least he leaves open a window so that you have a forlorn hope of building multiples. 
I hope that at least it doesnt take manufacturing space from the workshop. Not that it matters much.
Am I Seeing a ridesinged boarding gun too or its a new weapon?
It actually adds +10 workspace.
And what you're seeing is an upgraded Boarding Gun, a new weapon you can research.
I'll risk getting hate from everyone and suggest:
If such a thing is possible, why not adding the option of "executing" prisoners (and making sure the footage reaches faction hands or the opressed population) for monthly rating points and reminding everyone who's in charge here?*
That'd make little sense. The Traders etc. really cannot hate you more, and staging such stunts would undermine the source of your money - the Govts pay you because think you're useful (since you're a pain in Traders' etc. asses) and because they're lobbied by the Mutant Alliance who are useful as allies (to keep order) and who, in turn, think you're useful (for keeping mutants a little safer and for intimidating their opponents). Staging executions would alienate some of that power base, so would actually result in a lower score. The Mutant Alliance is known to be affiliated with various insurgents, but they would never tarnish their reputation by supporting people who stage executions of random people.
I get the messages for broken captives, what I'm talking about is the research popup. At midnight when an interrogation finishes, I get "research completed" but nothing where the name of the project should be.
That's for interrogations of non-broken captives. You then have to guess what just completed. It is even more difficult to guess when you interrogated a captive you have already interrogated (ie your 2nd trader engineer) and get no report because you got some unknown prerequisite for something without an actual UFOpedia page.
1. I can't do anything about this, this is how researching 'aliens' works in OXCom - no popup on what you have completed. You only get a popup with the further tech that got unlocked (ex. a Mission lore entry or a Vessel entry).
2. There is nothing of consequence which lacks an UFOpedia page, afaik. If you think there is, you might be right (errors happen) but you have to be more specific - whom you have interrogated etc.
