The Dirac Point as Necessity Depth Collapse: A Fibonacci Causal Loop Theory Pre-Registration of φ-Structured Quantum Critical Transport in Ultraclean Graphene

Fibonacci Causal Loop Theory (FCLT) predicts that necessity depth collapse events — S(0) states — produce φ-structured signatures in observable physical quantities. Paper 48 identified phase singularity annihilation as one such S(0) event (Davis 2026, zenodo.org/records/19634083). Here we identify a second independent S(0) system: the Dirac point in ultraclean graphene, where individual electron identity dissolves and collective Dirac fluid behavior emerges (Majumdar et al., Nature Physics 2025, DOI: 10.1038/s41567-025-02972-z). Two predictions are pre-registered against the publicly available source data from Majumdar et al.: P49a (active prediction): The peak Wiedemann-Franz violation factor at the Dirac point satisfies δ = |L₀/L₂ⁱ − φ¹¹| / φ¹¹ < 0.05, where φ¹¹ ≈ 199.005. Null: no φⁿ in [φ⁹–φ¹³] achieves δ < 0.05. P49b (confirmatory null): σ₉ = 4e²/h is fully explained by graphene’s 4-fold spin-valley degeneracy. FCLT predicts no φ-residual in σ₉ because the “4” is a structural degeneracy count, not a recursive necessity mechanism. Standard relativistic hydrodynamics (Son 2007; Fritz et al. 2008) fully accounts for this value. No source data files have been downloaded or analyzed prior to this submission.
