The verdict
Whether the programme is worth running.
The part
What it is
A decision rather than a report. Programmes continue because ending them is difficult rather than because the arithmetic supports them.
Where the verdict is negative, the winding-down question becomes the relevant one.
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.
