Erdős-Straus Conjecture as an S-Category Problem: Ricci-Flow + Fujimoto Infinity Algebra Attack Angle

Paper 109: Discrete Ollivier-Ricci flow categorisation places Erdős-Straus 4/n=1/a+1/b+1/c at 84.3% Category S (stable) for classifiable small n in [2,1000]. Combined with Fujimoto Infinity Algebra (FIA, STEP 843, 93/93 Lean 4 zero-sorry), suggests an algebraic-symbolic attack via degenerate-limit reasoning. Conjecture not claimed solved.
