Analysis of the Hawking temperature, Joule-Thomson coefficient, inversion curves, and isenthalpic trajectories shows that these parameters significantly modify the heating-cooling behaviour and thermal stability of the system. The deformation parameter $\\alpha$ and control parameter $\\beta$ shift the temperature minimum, enlarge the cooling region, and raise the inversion temperature, while $\\sigma$ produces a weaker but consistent influence"},"claims":{"count":4,"items":[{"kind":"strongest_claim","text":"The deformation parameter α and control parameter β shift the temperature minimum, enlarge the cooling region, and raise the inversion temperature, while σ produces a weaker but consistent influence;
