Clean φ-Framework Validation: Micro + Cosmic Only
==================================================

FOUNDATIONAL TRUTH:
D_{n,β}(r) = √(φ · F_n · 2^(n+β) · P_n · Ω) · r^k

STRATEGY:
1. Fit (n, β, Ω, k) to micro-scale data independently
2. Fit (n, β, Ω, k) to cosmic-scale data independently
3. Use fitting ERROR as signal (not noise!)
4. Let error adjust parameters toward framework consistency

NO hardcoded values. NO synthetic data. NO assumptions.
Just: framework normalization + per-scale tuning + error-as-signal
