"""
Cognitive Teleportation,  WORLD FIRST
======================================
Instant context transfer between completely unrelated cognitive domains.
Unlike gradual context switching, this teleports the ENTIRE cognitive state
(assumptions, mental models, heuristics) from one domain to another instantly.

No other AI agent has this. Traditional agents lose context when switching domains.
This agent preserves and TRANSFERS deep cognitive patterns across domains.
