//|                 Centaur Quant Architecture — Execution Module      |
//|             Anti-Veto Execution & Centaur-Edge Trade Manager       |
//+------------------------------------------------------------------+
//|  PURPOSE                                                          |
//|  Executes OB+FVG setups (SOrderBlockZone) as market orders via    |
//|  CTrade. Position size follows the Anti-Veto principle: the AI    |
//|  confidence score scales RISK only — it NEVER blocks execution.   |
//|  Dynamic management: low-confidence trades get an aggressive ATR  |
//|  trailing stop; high/moderate trades are left to breathe and only |
//|  move to break-even at 1:1 RR. The original score + initial SL    |
//|  persist in the order comment ("CEN:<score>:<sl>") so management  |
//|  survives terminal restarts.                                      |
