The coverage
What has no retention period.
The part
What it is
Usually most of it. Data with no schedule is kept indefinitely by default, which is a decision nobody made.
The uncovered list is the useful output and it is longer than expected.
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.
