Actual paths between ideal-fiber representatives at negative height

A fixed ideal element enters the expanding mixed-word box. Its support path can be based at the ray pivot even though the template does not contain zero.

    Source documentation

    Every fixed ray-ideal displacement can be realized at linearly negative height by an actual path with linear coarse speed and logarithmic error. The path constant is independent of the ideal displacement; the threshold is allowed to depend on it.

    Source documentation

    Unit-step representatives of the actual ideal-fiber difference. Every prefix retains a negative linear height margin, and remains in a linear ball about the ray pivot.
