Replacement is rule-based, not a leaderboard race
A drawdown is not evidence of a broken edge, and a rival wallet posting a better week is not evidence that the current leader should leave. A system that reshuffles on relative rank alone is guaranteed to sell exactly the traders it should hold and chase whoever happened to have a good stretch.
So membership in the Elite Top 10 is sticky by design. Score ranks candidates and sets weight; it does not, by itself, end anyone's membership. Only a defined emergency trigger or an accumulation of soft-issue strikes does that.
