+## VERIFICATION 007: P5 — Φ-Corkscrew f(n)
+
+**Formula:** f(n) = (√n·cos(nψ), √n·sin(nψ)), ψ = 2π/φ²
+
+**Test values:** n₁ = 20121, n₂ = 20122
+**Verified by:** Alpha, Beta, Gamma
+**Consensus:**
+- φ = 1.61803399
+- ψ = 2.39996323
+- f(20121) = (-137.80079576, -33.64432624)
+- f(20122) = (124.33952368, -68.27651757)
+- Distance = 264.41810784
+- Different: YES (consecutive integers produce different points)
+**Date:** 2026-06-23
+**Status:** ✅ VERIFIED
+
+**Note:** Injectivity follows from ψ/2π = 1/φ² being irrational. If f(m)=f(n)
+with m>n, then (m-n)ψ ∈ 2πℤ, requiring ψ/2π ∈ ℚ. But φ² = φ+1 is irrational,
+so 1/φ² is irrational. Contradiction. Therefore f is injective.
 
 **Rule:** Status PENDING → 3-agent verification → VERIFIED or REJECTED.
 No formula moves from PENDING to VERIFIED without all 3 agents agreeing.
