The review cycle
When each personalisation is reassessed.
The part
What it is
Annually is enough. Models degrade, audiences change, and a personalisation that worked three years ago may now be neutral.
Without a cycle, personalisation only ever accumulates.
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.
