# A Contract Should Have a Life, Not Just a Filename

A contract moves through draft, negotiation, approval, signature, amendment and supersession. That lifecycle should remain explicit instead of being reconstructed from folder names.

## UD model

UDR carries revisions. UDS preserves an exact final state. An amendment creates a new UDR.

## Boundary

UD coexists with current enterprise systems and does not by itself establish compliance or legal sufficiency.
