Calculation record
Canonical nonlinear spinor branches of the specified curvature parent.
One common unit radius, gap and local endpoint-current coupling are used.
The low parent space retains both frequency signs and both spatial Dirac
signs. Omitted high parent modes and the spatial tail are measured explicitly.
This is a conditional surface action, not derived particle confinement.
