The split
What share of published work sat under each pillar.
The part
What it is
Counted by pieces and by effort, because they diverge: one pillar can hold a third of the output and two thirds of the working hours.
Read over several periods. A single quarter reflects whatever happened to be in production.
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.
