  "abstract": "We investigate single-photon scattering and routing in an asymmetric cavity-waveguide quantum electrodynamics system consisting of a Jaynes-Cummings cavity-emitter subsystem coupled to two one-dimensional waveguides. Using a real-space scattering approach, we derive an exact three-channel scattering matrix and analytical expressions for the channel-resolved scattering amplitudes. The scattering response is governed by the interplay of asymmetric cavity-waveguide coupling, atom-cavity detuning, coherent preparation of a single-photon superposition across multiple input channels, and intrinsic dissipation. Coupling asymmetry controls the relative weights of the cavity-mediated scattering pathways, whereas atom-cavity detuning modifies their spectral response. Coherent multichannel input states provide an additional phase-sensitive control of the output probabilities through interference. In particular, we identify an analytical condition, $J_2=2J_1$ and $α_1=-α_2$, under which the probability in the second output channel becomes independent of photon energy; for an equal-weight normalized input, this probability is 1/2. We further show how cavity and atomic dissipation reduce the probability remaining in the guided channels. These results provide a framework for resonance-engineered single-photon routing in asymmetric Jaynes-Cummings cavity-waveguide systems.",
