The reader

Who takes the reading and who receives it.

The part

What it is

Separating who reads from who acts is usually a mistake at this level. The person watching an early signal should be close enough to respond.

Where they must differ, the handover has to be explicit or the signal is lost between them.

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.
