The streams

Each distinct source of revenue, with what triggers it.

The part

What it is

Distinctness is by trigger: a fee that arrives on a different event is a different stream, even if it appears on the same invoice.

Small streams belong in the map. They are where unmanaged margin and unmanaged effort usually sit.

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.
