The equivariant cohomological Hikita conjecture for quiver gauge theories

Claims the equivariant cohomological Hikita conjecture for all quiver gauge theories with regular stability: the flavor-equivariant cohomology of the Nakajima variety is canonically the coordinate ring of the scheme-theoretic stability-cocharacter fixed locus of the flavor-deformed Coulomb branch, including the empty case. It does NOT prove the quantized Hikita statement, nor extend to arbitrary reductive gauge groups, where Hikita-type identifications can fail, nor treat non-regular stability.
