Constant FP8_QUANT_REJECTS 

pub const FP8_QUANT_REJECTS: [&str; 3];

Every guard fp8_act_quant_hopper_reject can return, in the order it tests them — and therefore the log’s slot table. A list rather than bare literals at the call site because fp8_quant_log gives each ONE its own once-flag, and a reason with no slot would silently share another’s.
