After a period of inaction the orbital period of Cosmos 2519 dropped slightly from 97.909 minutes to 97.772 minutes during December 14-16.

Has there been any official conformation from the Russians that Cosmos 2523 is actually object E from this launch? - the object catalogued on October 31 in a 554-664 km orbit?

NK-forum:
23 июня Космос-2519 (14Ф150 "Напряжение" ), Космос-2521 (спутник инспектор), Космос-2523 (ПО) Союз-2-1В/Волга Плесецк 43/4 21:04:33

 (ПО) apparently analogous "TBD"

Russian friends can help ?

So it would appear that the people using the NK Forum haven't seen official confirmation either ...........

My last hope: the official information to the UNOOSA

Hate giving web links;
[2017-037E] Cosmos 2523
under UNOOSA Secretariat's remarks:
"The registration submission for this space object is presently being processed by the United Nations Secretariat. Date of launch is date of deployment from Cosmos 2521."

According to my informations, Cosmos 2519 is 14Ф150 №8120.

https://www.kosmonavtika.com/lancements/2017/23062017/23062017.html
No. 8120 does not seem to be 14F150 no. 2.
Rather no. 1.

Another explanation of the early references to №2, is that №1 was intended to fly on a different rocket?

There does appear to be a 14Ф150 №2:-

Cosmos 2519 has engine K50-10.5 from OKB Fakel.

http://www.fakel-russia.com/images/content/o_kompanii/letnaya_istoriya/KA_s_oborudovaniem.pdf

The K50-10.5 thruster is also mentioned in an article in the 3/2015 issue of the NPO Lavochkin magazine "Vestnik" about cooperation between NPO Lavochkin and OKB Fakel.

https://www.laspace.ru/upload/iblock/a81/a81ab7a06d732871d12138a11250f4cd.pdf
(see p. 35-36)

It is said to be 1.5 times lighter than the K50-10.1 thruster used on many Russian satellites. There is a unit consisting of a single K50-10.5 thruster called DB-1 and a unit consisting of three K50-10.5 thrusters called DB-3. Flight models of DB-1 and DB-3 were said to have been delivered at the time for "the first satellites of a new series, namely MKA-FKI (PN3) and EOKA". The same thruster will also be used by Lavochkin's Rezonans satellites.

MKA-FKI/PN-3 (also known as Konus-M) was a proposed astronomical satellite for gamma-ray and X-ray studies that has now apparently been canceled. Rezonans is a satellite for magnetospheric studies, four of which will be launched together in 2019. Testing of the K50-10.5 thrusters for Rezonans is described in detail in this article in the
3/2017 issue of Vestnik magazine.

https://www.laspace.ru/upload/iblock/676/676bc74dae2fe0e9da6e03b6d0a630a1.pdf
(see p. 27-35, with a drawing of the engine unit on p. 29)

EOKA might well be Kosmos-2519. I can't immediately find any other reference to it on the web. "E" usually stands for "experimental" and "KA" for "kosmicheskiy apparat" ("satellite"). Could the "O" stand for "optical"?

Both MKA-FKI/PN-3 and Rezonans are designed on the basis of the Karat-200 bus, so there's a good chance that EOKA uses the Karat-200 platform as well.

More technical information on the K50-10.5 thruster can be found in this English-language brochure of OKB Fakel.

That's usually translated as "optiko-elektronnyy" (оптико-электронный), so in that case you would expect OEKA rather than EOKA.
