The signal
When the comparison means trouble.

What it is
Consumption running well ahead of progress means the date will not hold, and it is visible long before it is undeniable.
A stated threshold turns the comparison into an action rather than an observation.

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.
