Whiteboard

nsdef:whiteboard

whiteboard — a NAMED bundle of a client's self-directed state (its pins and its focus), the client's own layer: world-ignorable, dying with the session, and never able to widen an IAM grant. A board IS its pins Set (set:wb:whiteboard:<board>:pins, stored on the Workbench); a pin is a MEMBERSHIP taken at the bench clock, so pinning adds and unpinning ends one, and what a board held at a given moment stays readable. The focus is a coordinate, not a pin: it moves while the pins stay, and switching or recreating a board erases neither. Ops are whiteboard.* (renamed from wb.*, which is the bench namespace).
