The requirements

What the person must be able to do, separated from what would be convenient.

The part

What it is

Every requirement excludes people. Requirements that are not genuinely required exclude people for no return, and they exclude unevenly.

The discipline is to ask, for each line, what happens if the person cannot do this. Where the answer is “they learn it in a month”, it is not a requirement.

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.

Requirement
Stated as a demonstrable ability rather than as a credential where possible.
Text shared type
Essential or desirable
The split is what keeps the desirable list from silently operating as a filter.
Choice shared type
Why required
Forcing a reason removes about a third of the list on first pass.
