One identity · The customer route · Element
The mechanism
How a customer links records.
The part
What it is
Signing in, entering an order number, or confirming a code. Each has a different effort and a different success rate.
The route should be available at the moment the benefit is apparent rather than in a settings page.
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.
