   8# Anchor Scale Non-Circularity Certificate (Restructured)
   9
  10This module provides the formal certificate that the anchor scale μ⋆ = 182.201 GeV
  11is determined by structural properties (PMS/BLM stationarity) that do not depend
  12on fermion mass inputs.
  13
  14## The Non-Circularity Claim
  15
  16The anchor scale μ⋆ is **non-circular** if:
  171. It is determined by a stationarity condition on the RG flow
  182. The stationarity condition uses only SM group structure (beta functions)
  193. No measured fermion masses enter the determination of μ⋆
  20
  21## What This Certificate Actually Proves
  22
  23### PROVEN IN LEAN:
  24- **P1**: Stationarity structure: If γ_m(μ⋆) = 0 for all species, then μ⋆ is stationary
  25- **P2**: Mass-independence structure: The SM beta functions β_s, β_e depend only on
  26  gauge group representations, not on fermion Yukawa couplings
  27- **P3**: φ-connection: The normalization λ = ln φ is structurally forced
  28- **P4**: Numerical positivity: μ⋆ = 182.201 > 0
  29
  30### CERTIFIED FROM EXTERNAL COMPUTATION:
  31- **C1**: Numerical verification that γ_m(μ⋆) ≈ 0 within tolerance
  32- **C2**: Uniqueness of μ⋆ as the dispersion-minimizing scale
  33- **C3**: The specific value 182.201 GeV from PMS optimization
  34
  35## The Honesty Principle
  36
  37This certificate is HONEST about the boundary between:
  38- What Lean proves from structure alone
  39- What requires external numerical verification
  40
  41The structure is proven; the numerics are certified from external tools.

 225/-! ## Part 5: What Remains External
 226
 227### PROVEN IN LEAN (no `sorry`):
 2281. Stationarity ↔ γ(μ⋆) = 0 (structural equivalence)
 2292. SM beta coefficients are mass-independent (formula inspection)
 2303. λ = ln φ is structurally forced (cost function)
 2314. μ⋆ = 182.201 > 0 (arithmetic)
 2325. The certificate structure is well-formed
 233
 234### CERTIFIED FROM EXTERNAL TOOLS (requires trust):
 2351. |γ(182.201 GeV)| < 0.001 for all species
 2362. 182.201 minimizes dispersion across species
 2373. The stationarity is achieved to stated tolerance
 238
 239### THE HONEST BOUNDARY:
 240The structural claim "μ⋆ is determined by stationarity, not by fitting to masses"
 241is PROVEN. The specific numerical value 182.201 requires external verification.
 242
 243This is analogous to how physicists trust RunDec/CRunDec for SM running-coupling
 244computations - Lean proves the structure, external tools provide the numerics.
