Artian Source-Only SI Closure: the K2 Caesium Hyperfine Source Packet Theorem

One caesium landing, three transfer failures, and the source law that must replace it Version: 8.0 Concept DOI: 10.5281/zenodo.21249436 Author: Ali Attar Website: quantumtraction.org Main book anchor: Quantum Traction Theory: Main Book v10.01 The 2019 SI defines the second through the caesium-133 hyperfine frequency. In QTT, complete source-only SI closure is therefore concentrated into one dimensionless bridge: \[ NK2 = tA\,ΔνCs ={A\,ΔνCs}{c} =α_λ^2/4π {m_eˢᵒᵘʳᶜᵉc^2}{E_} ΦCsˢᵒᵘʳᶜᵉ. \] The exact K2 reduction and the sealed caesium target remain unchanged. Version 8.0 asks the harder questions that one very accurate landing cannot answer: which nuclear and electronic factors are identifiable, and does the frozen caesium word transfer to other alkali clocks without changing a coefficient? For a neutral alkali (nS1/2) clock row, the observable packet is \[ Φ_Aˢᵒᵘʳᶜᵉ =8/3I_A+12/I_A {α_λ^2}{μₚₑQTT} { G_Aⁿᵘᶜ}nuclear magnetic source { CnS,Aᵉˡ}electronic contact and access, ν_Aᵖʳᵉᵈ=cR_∞source,QTTΦ_Aˢᵒᵘʳᶜᵉ. \] One clock frequency fixes only the product. The transformation \[ G_Aⁿᵘᶜ↦λ G_Aⁿᵘᶜ, CnS,Aᵉˡ↦λ⁻¹ CnS,Aᵉˡ \] leaves the observable unchanged. Version 8.0 proves this product-gauge non-identifiability exactly. It also proves that writing a known positive target as (M=Be-I) is a reparameterization, not a derivation, unless the source law fixes (I) independently before the target is opened. The v7 candidate is then frozen with no new coefficient or atom-specific repair: \[ κ_A=Z-1/n, η_A=A-2Z+1, s_A=2I, \] \[ I_Aⁱᵈ =κ_A/128ρ +1/1024√3\,ρ^2 (1+1/η_A s_A^2ρ), M_Aⁱᵈ=32e^{-I_Aⁱᵈ}. \] The resulting blind transfer residuals are \[ {array}{c|rrrr} row&{}¹³³{ Cs}&{}⁸⁷{ Rb}&{}⁸⁵{ Rb}&{}³⁹{ K}\\ 100(νpred/νobs-1) &-9.15×10⁻⁷%&+57.30%&+218.73%&+2236.89% {array} \] The rubidium sibling-isotope ratio is even cleaner because both rows share the same element and (5s,{}^2S1/2) electronic shell: \[ .{ν(⁸⁷{ Rb})}{ν(⁸⁵{ Rb})}|ᵥ₇ =1.11111109637, .{ν(⁸⁷{ Rb})}{ν(⁸⁵{ Rb})}|obs =2.25141139252. \] The frozen identity word is therefore rejected as a universal alkali hyperfine source law. The exact K2 factorization, the source Rydberg relation, and the caesium packet as a sealed audit target are not rejected. What is now sharply localized is the missing positive construction: a QTT-native nuclear magnetic operator and an independently evaluated electronic-contact/access operator that transfer across isotopes and elements.
