A reciprocal symmetry z↔1/z is identified in KNO scaling violations in pp collisions at 7-13 TeV, imposing P'(<n>)=-P(<n>)/<n> and enabling entanglement entropy extraction from the central multiplicity region.
The reciprocal symmetry of the KNO-violating term yields the new constraint δ₃=0 at n=⟨n⟩ (untestable at present precision), fails globally at 13 TeV, and the derived entropy S=ln⟨n⟩+I₀−½∫e^{-z}f_s²dz matches ATLAS data at 10⁻³.
An approximate formula for the entropy of the negative binomial distribution is provided, with up to ~20% deviation from exact values for extreme parameters.
Including soft gluons in Monte Carlo generators for DIS aligns parton distributions with inclusive PDFs and makes entropy grow with decreasing x, indicating initial-state origin of the bulk entropy.
