What it is
Boundary cases arrive with a deadline attached, which is why the route has to exist before one does.
Recording the rulings builds a precedent set that makes later cases faster.

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.
