The verdict
Whether to run it.
The part
What it is
A test that cannot detect the effect that matters should not be run. It costs the same and produces something worse than nothing.
Where the volume is inadequate, judgement plus observation is a more honest basis than a test that cannot conclude.
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.
