The sequence

What happens before what.

The part

What it is

The order is behaviour first, evidence available second, messaging third. Reversing it wastes the messaging and damages credibility.

The temptation to announce early is strong and it is the most reliable way to make the effort fail.

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.
