Trajnica je stabilna putanja ili obrazac po kome Tango može da traje i da se ponavlja.
Why this term exists
A coordinated relation becomes durable only when it can return along a recognisable path. Trajnica names that stable path or pattern, connecting repeated Tango with persistence through change.
Definition in the system
A stable path or pattern along which coordinated relation can endure and repeat through change.
Canonical boundary / operational note
Tango stvara Trajnicu; Trajnica nosi sledeći Tango. TANGLE → UTAKTAVANJE → TANGO → PONAVLJANJE I TRAJANJE → TRAJNICA.
