The Primitive-Square Pair Types the Reciprocal Split While the Square Current Alone Forgets Phase and Incidence
For
the first connected grades are
The square grade determines the radial discriminant but forgets the phase bit
sigma: it cannot distinguish splitting through r=-1 from splitting
through r=+1. If the factor occurs in a denominator rather than a numerator,
both grades reverse without moving its roots.
Therefore the square current is an order parameter only inside a fixed typed presentation. The globally meaningful object must retain the coupled primitive-square packet together with determinant incidence distinguishing section zeros from carrier poles and reciprocal-chart coherence.
This is the necessary scope correction to Ledger 3366 and explains why local Euler/Tate off-unit singularities do not themselves predict off-seam zeros of the completed section.
