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.
