"""Check for 06-own-mark (derivation v2).

Exact diagonalization of the total contract in the sectors (k, P) for one field
object (N_f = 1) on rings of two sizes, for the couplings (a) and (c), three clock
levels and both branches.  Compared with the second-order results of the
derivation: dressed level E_{k,sigma}(0) (6.5)-(6.6), clock spacings (6.8), and
curvature E''_{k,sigma}(0) (6.10) with the leading-tau^2 forms (6.11), and the inertia-cost comparison (6.12).
The curvature of the exact level is the exact derivative of the eigenvalue of
the sector matrix C(P) (6.1) at P = 0 (second-order Hellmann-Feynman formula).
