φ is forced as the unique positive solution to x² = x + 1 by self-similarity in a discrete J-cost ledger (phi_forced, phi_forcing_complete, phi_equation).
In RS-native units (ℓ₀ = τ₀ = 1):
- c = ℓ₀/τ₀ = 1 (c_rs_eq_one).
- ℏ = E_coh · τ₀ = φ^{-5} (ℏ_rs_eq, E_coh_pos).
- G = φ^5/π (G_rs_eq, G_pi_eq_phi5).
Further identities: G · ℏ = 1/π (G_ℏ_product); J_bit = ln(φ) (J_bit_pos).
