The confounders

What else changed during the period that could explain the difference.

Improvement rarely happens in isolation. Volume changes, staff changes and seasonal effects all move the same numbers.

Naming them does not resolve them, and it prevents a coincidence being recorded as a success and repeated elsewhere.

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.
