The outcome
What happened.
The part
What it is
For taken opportunities, against what was expected. For declined ones, what happened to them elsewhere.
Checked at the horizon the expectation named rather than when it happens to come up.
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.
