The refresh queue
What still works and needs updating.
The part
What it is
Ordered by use rather than by age. The oldest piece is not the one worth an afternoon; the most used piece that has drifted out of date is.
A refresh is cheap and rarely scheduled, which is why the queue exists as an artefact rather than as an intention.
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.
