What it is
Including nothing, since a series of unchanged readings is the finding that the market is not moving.
It also makes the eventual movement visible as a change rather than as a sudden discovery.
The smallest level

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.
