Hilariously, all of the "evidence" that you post to prove that I was being dishonest when I stated that the OPCW have never identified Novichok, not only proves my point but also makes clear that whatever was identified in the samples of the Skripals and Navalny definitely wasn't Novichok.
How can we know this? Careful reading of the letter that you linked to and quoted from earlier makes this clear. The letter that doesn't "necessarily reflect the views of all organizations and individuals within the CWC Coalition.".
Novichok agents, also known as fourth generation agents (FGA), are a class of nerve agents
developed by the Soviet Union during the Cold War. These nerve agents emerged as a modern
CW threat due to their use in the attempted assassinations of Sergey Skripal in April 2018, in
Salisbury (UK), and Alexei Navalny in August 2020, in Omsk (Russia).
Novichok agents can be divided into four families of chemicals based on their chemical
structures. The 2019 amendment to the CWC schedules provides comprehensive coverage of two
of these families, partial coverage of a third family, and no coverage of a fourth family. This is
particularly worrisome since the Novichok agent used in the attempted assassination of Navalny
in August 2020 was likely a toxic chemical from that fourth family. Hence, the next logical step
is for the States Parties to extend the coverage of Novichoks by the CWC Schedules by adopting
a family-based approach for all four groups of Novichok agents.
So the agent identified in samples from the Skripals and Navalny was "likely" from a fourth "family" used in the "attempted assassination". "Attempted assassination" should have made you aware that it isn't an official OPCW communique. An official body would never use such charged language unless the charge was proven.
The agent identified, therefore, is definitely not a Novichok. The partisan authors and co-signers of the letter are "requesting" that the agent be added to the Novichok family.
Given that we have been told, repeatedly, that Russia must have done it because they developed Novichoks, it seems odd that this is a new type of agent("likely" from a toxic chemical from a fourth family) which our partisan authors, are requesting is listed as a Novichok. So the agent in question identified is not listed as a Novichok.
The agent in fact is part of some other previously unidentified "fourth" family of Novichoks. Whatever agent was used, pressure is now being exerted on the OPCW to list an entirely new fourth family.
Well done for finding this letter, David. In your failed attempt at proving that the OPCW have identified Novichok use, you inadvertently discovered the attempts by partisan actors to widen and include new agents as being in Novichok class of agents to four families. Widening the "parameters" of what constitutes Novichoks so as to be able later to claim that Novichok is defenitely identified. If you cannot see through the attempted deceptions, it can only be wilful at this point.
