The reallocation
What changes as a result.
The part
What it is
Where effort moves, which segments are de-prioritised, and what that costs in short-term revenue.
The short-term cost is real and is why the reallocation is usually discussed and not made.
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.
