/**
 * One member's place in the board: what it has been handed, whoever handed it.
 *
 * A member is handed posts two ways: by the workflow at the top of its turn,
 * and by its own `read`. With a cursor for each, a `read` after the handout
 * gave back what the handout had just given. Measured in a real pi: a member
 * handed a post read the board at once and was handed it again, and a `read`
 * in round four returned posts from rounds two and three. The cursor is
 * therefore the member's, and both ways move the same one.
