Coordinates form a finite type I and each actual coordinate i has its own finite nonempty alphabet X(i). A history is an injective ordered sequence of actual coordinate identities with dependent results. Appending an unread coordinate has a unique inverse consisting of its parent, coordinate and letter. A full history determines the complete named assignment without renaming coordinates.
A flow consists of nonnegative real node, selection and result masses. Its root mass is one; selection masses sum to the node mass, result masses sum to the selected flow, every result is bounded by the actual coordinate capacity times its selection mass, and each child node has its incoming result mass. Terminal projection sums node masses over every full ordering with the given named assignment.
At positive nodes and selections, scheduler and result rows are the corresponding mass ratios. Null nodes use the uniform unread-coordinate scheduler and null selections use the uniform row of the actual dependent alphabet. The only capacity premise needed by this construction is that each capacity is at least the reciprocal alphabet size; the original upper bound of one and nonempty coordinate set remain valid specializations.
Independent finite scheduling and result tables supply every row. The actual adaptive recursion reads the current entries at its realized previous history. Structural history-fiber identities and induction show that the resulting trace has exactly every prescribed node mass, including all null branches. Dependence of result rows and coordinate choice on the previous history is allowed; independence of innovations does not assert independence of output coordinates.
