Struct SpoofingEngine 

pub struct SpoofingEngine { /* private fields */ }

Spoofing engine for adversarial mode.

Spoofing makes suspicious transactions appear more legitimate by:

• Aligning timing to customer’s normal cadence
• Sampling amounts from customer’s historical distribution
• Using merchant categories consistent with persona
• Adjusting velocity to match baseline behavior
• Adding longer dwell times to avoid detection
