Geometric hit-auth (rewind / cadence / LOS) stays on the Game Thread in TFACombat / TFAWeapons. Statistical anti-cheat, economy/marketplace fraud signals, and case-log writes go to MonetaryPlatform UAntiCheatSubsystem off the hot GE path (workers; FS-ARCH-012 / FS-ARCH-013). Combat never owns the case store; it only submits worker signals.
