The worlds

Each described future, with enough detail to be recognisable.

The part

What it is

A scenario is written as a description of a world, not as a forecast with a probability. Naming it memorably is a small thing that makes it usable in conversation.

The test of enough detail is whether someone could say which scenario they think is arriving.

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.
