Certificates / CONCEPT

Oh and Scrimshaw's two-shifted q-Motzkin conjecture is false as printed

At n = 3 the two-shifted Hankel determinant of Cigler's q-Motzkin numbers takes the value 3 at q = 1, while the printed factor f_3 takes the value 2, so no power of q times f_3 equals the determinant.

Authority boundary

Dependency edges, status, and source coordinates come from the verified release and certified topology. Blueprint exposition is labeled separately. A fallback title carries no additional mathematical authority.
