The MLL floor no longer recomputes while a position is open or while the balance disagrees with the books beyond fee noise — the last settled floor stands, so balance ≤ floor can only come true when a booked fill crosses a settled floor (Topstep's own liquidation fill included). The floor also survives canTrade flipping off, so a blown account stays ☠ instead of demoting to inactive. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
