XIIC

N. Cheung, Landmark XII-C, supplied manuscript, version 1. Locators: eq:finite-curvature, eq:ell3, eq:Ccoefficients, and thm:actualsource. The density atoms and selected $C_2$ source are specified explicitly in the present manuscript.

XIID

N. Cheung, Landmark XII-D, supplied manuscript, version 1. Locators: eq:B-kernel and lem:root-kernel. The root's existence, compactness, and $Z_2$ bound are retained as Assumption ass:root.

XVIJ

N. Cheung, Landmark XVI-J, supplied manuscript and revised formulation. The retained interfaces are the dual-basis constant-slot contraction, selected square extension, and conditional root attachment. The exact regression target is displayed in Proposition prop:regression, independently of changes to predecessor equation numbering.

Artifacts

N. Cheung, Computational artifacts supplied with Landmark XVI-K: hessian_full.py, xvi_common.py, recompute_K_dual.py, and hessian_full_out.txt. Exact-arithmetic coefficient expansion and supplied verification record. These artifacts are unchanged.
