Calculation record
Local first-order tensor chain with a controlled curvature-frequency branch.
The round S^(d-2) is a specified spatial field feature in ordinary R^d.
Its tensor fields, common gap and radius are inverse inputs. The chain
supplies a causal linear parent for an effective polynomial; it is not
a derived master-field surface or a complete particle inertia model.
