7# Planck-Scale Matching: Conjecture C8 Derivation
8
9This module formalizes the derivation of λ_rec ≈ 0.564 ℓ_P from the
10ledger-curvature extremum argument.
11
12## The Derivation Chain
13
141. **Bit Cost (J_bit)**: From the unique cost functional J(x) = ½(x + x⁻¹) - 1,
15 evaluated at the self-similar scale φ, we get J_bit = J(φ) = cosh(ln φ) - 1.
16
172. **Curvature Cost (J_curv)**: A ±4 curvature packet distributed over the 8 faces
18 of the Q₃ hypercube (the 3-cube) gives J_curv(λ) = 2λ² in RS-native units.
19
203. **Extremum Condition**: At equilibrium, J_bit = J_curv(λ_rec), which determines
21 the recognition wavelength λ_rec.
22
234. **Face-Averaging → π**: Restoring SI dimensions via c³λ²/(ℏG) and averaging
24 over the 8-face geometry introduces the factor 1/π.
25
265. **Planck Ratio**: This yields λ_rec = √(ℏG/(πc³)) = ℓ_P/√π ≈ 0.564 ℓ_P.

2792. ✓ J_curv(λ) = 2λ² (from ±4 curvature on Q₃)
2803. ✓ Extremum: J_bit = J_curv(λ_rec) determines λ_rec
