  "abstract": "The Fourier–Kontorovich–Lebedev (FKF) transform is a hybrid integral transform whose kernel is the product of a Fourier exponential factor and the Macdonald function of purely imaginary order. Its rigorous extension to generalized functions rests on a carefully constructed testing-function space equipped with a countable family of seminorms. This paper presents a detailed mathematical account of convergence in that testing space. We define the multinorm topology, state the precise notion of sequential convergence, contrast it with weaker pointwise notions, and explain why the topological formulation is indispensable for justifying differentiation under the transform sign, passage of limits, continuity of the distributional pairing, and spectral monitoring applications in multi-scale supply-chain systems. Illustrative figures depict seminorm decay, the underlying domain Ω, the spectral plane, and the distinction between pointwise and topological residuals.",
