Tom, if you read the Bagley book it's difficult not to conclude that Nosenko was more than he said he was. Or less. That is he was, a ruse, a fake sent by the KGB for whatever reason; probably primarily to show they didn't recruit Oswald and therefore they were not connected to the assassination.
The Bagley book is here: https://cdn.preterhuman.net/texts/government_information/intelligence_and_espionage/Spy.Wars.pdf
For example (this is in the book), the CIA interrogators, including a KGB officer who had defected and was working with them, asked Nosenko to write a cable to KGB headquarters to show that he knew the simple basics of his job. As in: "Show us how you'd write a cable, please". According to Bagley he didn't even know these basics - the format, how to address it, et cetera, something any agent would know. And when asked to describe KGB headquarters - where his office was, where the main cafeteria was, how to get to it - he couldn't give any details. There were numerous other examples of his failure to explain how an agent would do simple tasks.
Then, of course, when he said the KGB never formally questioned Oswald - when the CIA knew that other American defectors were closely interrogated - alarms went off.
So there is strong evidence that he wasn't who he said he was.
But one has to include this other evidence: the KGB files given to Clinton, the interviews with Belarus KGB agents who monitored Oswald, the reports of other KGB agents who later defected - like Kalugin - who say Nosenko was a real defector that caused problems for the KGB. I think if you look at the totality of evidence you'd have to conclude that he was genuine and not a fake. Probably, as Kalugin said, an incompetent KGB agent, a drunk, a womanizer but an authentic one.

Have you actually read Bagley's
Spy Wars?
It doesn't sound like it.
Facts:
In 1962, Angleton (for whom Bagley did NOT work) asked Bagley (who at that time still believed Nosenko was a true quasi-defector) to read Anatoliy Golitsyn's top-secret file. Golitsyn had defected to the U.S. on December 15, 1961, about six months before Nosenko "walked in" in Geneva. When he did read it, Bagley realized that everything Nosenko had just told him and (probable mole, imho) George Kisevalter in Geneva not only implausibly overlapped what Golitsyn had told CIA, but CONTRADICTED it ... and therefore Nosenko must be a false defector.
And he was right.
Bagley trusted Anatoliy Golitsyn.
So do I, and I'll tell you why if you really, really want me to. (Hint: I has to do with Golitsyn's "production," i.e., his uncovering of KGB moles and triple-agents, mostly in OTHER countries like France and Britain.)
(I say "quasi defector" because Nosenko told Bagley and Kisevalter in Geneva that under no circumstances was he going to defect to the U.S., that he was going back to his wife and daughter in Moscow, "and please, please, please don't try to contact me there -- maybe I'll contact YOU at some point in the future.")
Golitsyn predicted that the USSR would break up, and said it would do so intentionally in order make us drop our guard.
I give you the ill-advised (by Michael McFaul) 2009 "Reset," Anna Chapman and the Eleven Dwarfs Spy Ring (finally rolled up in 2010), Marina Butina and her U.S.-based handlers, Brexit, the GRU's hacking of DNC's emails and distribution of same through Putin's agent Julian Assange, and "useful idiot" (or worse) President Donald John Trump, etc.
With very few exceptions, the adage "Once in the KGB, always in the KGB" is spot on.
Why in the world would you trust what some "former" KGB dude in Belarus said about anything, or what Nechiporenko, Kostikov, Yatskov and Leonov said about "Oswald" in Mexico City?
Yep. Leonov, Nikolai. The KGB lieutenant colonel (and mentor to Raul Castro and Che) whose diplomatic cover was "Third Secretary and Assistant Cultural Attache" at the Soviet embassy (not the consulate) who claimed in the 1990s that Oswald had showed up at the embassy on SUNDAY, SEPTEMBER 29 when they were already playing a volleyball game, and that he got all emotional and brandished a revolver as they were talking one-on-one in Leonov's office ... one day after "Oswald" had supposedly done exactly the same thing at the consulate.
LOL
Read Riebling's book and Bagley's PDF as well, lad.

PS Please remember that Nosenko originally claimed that the KGB not only didn't interview the Marine Corps radar operator, it didn't MONITOR him, either.
Question: How much drinking did Nosenko do during the three years or so he was subjected to "harsh, solitary-confinement interrogation" (at the insistence of Soviet Russia chief David Murphy, not Bagley or Angleton)?
Answer: None.
Bagley said Nosenko did drink heavily in Geneva in 1962, and for a few months in the U.S. before he was "incarcerated," but that he never slurred his more-than- adequate English and never appeared to him to be drunk. Their six meetings in Geneva were tape recorded, btw ...
