What moved

How the final differs from the original ask, and why.

The part

What it is

This is the audit trail of the negotiation. It answers the question a reviewer will ask later about why the commitment is not what was originally requested.

A pattern of the ask always winning, or always losing, both point at a problem with the practice rather than with any one round.

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.
