Abstract: Within the UNNS Grammar, Operator XIV (Φ-Scale) expresses the universal law of recursive scale symmetry: the principle that the grammar of nesting reproduces itself at discrete magnifications governed by the golden ratio φ ≈ 1.618. This operator bridges Operator Interlace (XIII) — the coupling of phases — with Prism (XV) — the spectral decomposition of those couplings — by introducing a self-similarity constraint on the grammar itself. In the Φ-Scale Chamber, this symmetry manifests as a minimum of the Δ_scale(μ) functional, signaling that recursion has discovered its own invariant scale. This is not φ inserted by hand — it is φ emerging as the only ratio where recursion recognizes itself perfectly across magnification.
