Current drafter models are far from optimal, with model gap accounting for 43-64% of DFlash rejection and 85-92% of DSpark's oracle-conditioned rejection at the final slot

current drafters remain far above their floors: the final-slot model gap accounts for $43$--$64\%$ of DFlash rejection and $85$--$92\%$ of DSpark's oracle-conditioned rejection
