- Replace all raw pos["key"].(type) assertions with posFloat64/posString/posInt64 helpers across auto_trader_decision, auto_trader_grid, auto_trader_grid_orders, auto_trader_grid_regime, auto_trader_loop, auto_trader_orders, auto_trader_risk - Add posInt64 helper for int64 extraction (createdTime etc) - Fix emergencyExit: log CloseLong/CloseShort errors instead of silently dropping - Fix emergencyExit: log GetPositions error on failure - Upgrade closeAllPositions log level from Infof to Warnf for close failures - Zero raw type assertions remaining in auto_trader_* files
