The entries
Each change during delivery.
The part
What it is
Including the ones agreed informally, which are the majority and are the ones that accumulate.
A change agreed in a conversation and not logged is invisible in the eventual explanation.
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.
