The exception log

What departures were approved, and why.

The part

What it is

The log is where the pattern shows. A rule departed from repeatedly is a rule that does not work in practice.

It also prevents each exception being argued from scratch, since the precedent is visible.

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.
