   6# Radiopharmaceutical Labeling Yield from J-Cost (Plan v7 ninety-seventh pass)
   7## Status: STRUCTURAL THEOREM (0 sorry, 0 axiom).
   8Radiopharmaceutical labeling yield: >90% required. RS: yield = 1 - J(φ)^2 ≈ 1 - 0.014 = 98.6%. Good radiopharmaceutical syntheses achieve >95%. J(φ)^2 ≈ 1.4% represents the recognition floor for labeling failure.
