Struct AlertDeduplicator 

pub struct AlertDeduplicator { /* private fields */ }

Tracks event IDs already admitted so repeated recalculation (e.g. rollback/idempotent replay of the same bar) does not re-emit duplicate alerts downstream.

Returns true and records the event if its ID has not been seen before; returns false without side effects if it is a duplicate.
