RMSNormGated does not subclass RMSNorm, so it missed the name-based quantization exclusion and the global INT4 spec (per_block, axis=1) was applied to its rank-1 weight, raising "axis 1 out of bounds for tensor of rank 1". Add its module path to _TORCH_MODULE_EXCLUSIONS alongside the other RMSNorm composite variants.
