Ians,
Nowhere does the report mention novichok by name.
A deliberate omission. I think not.

It was named and its chemistry described in the full report.
In the open report it said it confirmed all the British conclusions.

Guardian,
"The international chemical weapons watchdog has backed the UK’s findings on the identity of the chemical used to poison the former Russian spy Sergei Skripal and his daughter Yulia in Salisbury."

"The executive summary released by the OPCW does not mention novichok by name, but states: “The results of the analysis by the OPCW designated laboratories of environmental and biomedical samples collected by the OPCW team confirms the findings of the United Kingdom relating to the identity of the toxic chemical that was used in Salisbury and severely injured three people.” "
