The placement
Where in the plan it sits.
The part
What it is
Before the commitment date, as a single visible block. Spread across tasks it is absorbed silently and protects nothing.
Where several strands converge, the buffer belongs at the convergence.
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.
