  "abstract": "Parker Solar Probe (PSP) revealed the ubiquity of switchbacks (SBs), sharp, localised magnetic deflections in the nascent solar wind, renewing interest in their origin. One proposed mechanism involves solar jets: collimated, impulsive features driven by magnetic reconnection that launch Alfvénic torsional wavefronts into the heliosphere. We test whether realistic spacecraft sampling of a propagating solar jet produces in-situ signatures consistent with PSP observations. We also examine the 3D magnetic topology of the resulting structures and how deflection amplitudes evolve with the ambient plasma environment. We perform a 3D magnetohydrodynamic simulation of a solar jet in the ambient solar wind, embedding a virtual spacecraft trajectory based on PSP's actual 22nd-perihelion orbit to generate synthetic measurements. The simulation reproduces SB-like signatures with durations and profiles consistent with PSP observations, confirming earlier results from simplified trajectories. We visualise the fully 3D magnetic topology of a jet-driven SB region, identifying two field-line families: one with a single deflection and another with two sequential deflections along the same field line. Both are outward-propagating Alfvénic structures. Deflection amplitudes depend strongly on background plasma $β$, increasing substantially in low-$β$ regions and evolving more moderately where $β\\sim 1$. These results show that solar jets can produce Alfvénic, SB-like structures along realistic spacecraft trajectories. Their topology is inherently 3D and structurally diverse, and their evolution depends on ambient plasma $β$. Complete magnetic reversals would require longer residence times in low-$β$ environments. Our findings support a solar origin for a fraction of SBs and constrain interpretations of their underlying magnetic structure.",
