The registration
How a route claims an opportunity.
The part
What it is
A simple first-claim system with an expiry, so that a registered deal that goes nowhere does not block the opportunity indefinitely.
The expiry is the part usually missing, and its absence turns registration into a land grab.
The smallest level
The attributes it carries
Each attribute is one of the framework’s shared types. What a date is, and how it is written, is defined once for the whole model — the note here says what it means in this particular place.
