This paper derives the principle of stationary action from the Primitive Bifurcation Law

of the Void Dynamics Model (VDM), showing that the familiar variational rule is not

an independent postulate but the temporal-path effective invariant generated when the

primitive non-discharge law is expressed on an admitted temporal domain. CF 000 proves

that same-domain articulation cannot continue indefinitely: once lawful invariant-bearing

articulation within a domain is exhausted while discharge remains impossible, orthogonal

re-articulation into a new irreducible domain is forced. The universal axiom paper A(−1)

sharpens this constitutional picture: void debt begins exactly at the saturation limit, and

every later invariant and later axiom is effective rather than primitive. CF 00 then makes the
