Inspected and fully functional as of 2021 via the joint inspection program with the US that RU has since backed out of.
I don't think those inspections were that thorough or comprehensive.
The inspections are to verify locations of warheads and delivery systems. They are not function tests. They do not verify fuel integrity, structural integrity, nav hardware functionality or any other critical function. They don't even check that all the components exist in the delivery system.
These parts (fuel, computer components, chassis components) are all valuable on the international black market. The scalpers who have, for decades, been the main sources for these commodities have been the poorly paid people who maintain these systems.
