We present a Planet Nine candidate identified through a novel methodology combining the scale-relativistic quantization of planetary orbits with multi-epoch far-infrared survey cross-matching. Fitting the macroscopic quantization law a = Kₐ·n² to the semi-major axes of Jupiter through Neptune (n = 3–6) yields Kₐ = 1. 191 ± 0. 086 AU with R² = 0. 9998, predicting a trans-Neptunian planet at a = 386–430 AU for n = 18–19. A shifted cross-match of IRAS (1983) and AKARI (2006) reveals a top candidate (score 86. 1/100) at (α, δ) = (99. 968°, +3. 190°), d ≈ 595 AU. Multi-wavelength follow-up across twelve databases shows: (i) a CatWISE2020 source at 2. 2″ with W1-W2 = 1. 55, μ ≈ 0. 2 mas/yr; (ii) thermal emission peaking at 140 μm (AKARI FIS: F140 = 1. 82 Jy), T ≈ 21 K — nearly twice the equilibrium temperature (Teq = 11. 4 K), consistent with internal heating; (iii) three Gaia DR3 sources within 30″ with zero proper motion; (iv) nine stationary Pan-STARRS1 detections; and (v) dynamical resonance matches with Sedna (13: 9, Δϖ = 175. 5°) and 2015 RX245 (23: 18, Δϖ = 153. 7°). Foreground contamination is excluded. The candidate's physical properties (HV ≈ -6. 7, D ≈ 94, 000 km for pV = 0. 1) are consistent with a ∼5 M🜨 ice giant. Orbital elements, 2026–2027 ephemerides, and observing strategies for Rubin, Subaru/HSC, and Gemini are provided.
