This study uncovers how local strain reshapes the spin landscape of a single Ni${}^{2+}$ ion ($S$=1) embedded in a charged semiconductor quantum dot. It reveals how strain anisotropy, spin--carrier exchange, and subtle symmetry breaking create rich optical signatures -- offering new pathways to probe, model, and control individual spins for quantum technologies.
