Artian's HVP Source-Access Reference Framework

BaBar ISR as an instrument test, before it becomes a pion-source verdict This release concerns the BaBar \(e^+e^-\to\pi^+\pi^-\gamma\) row in the hadronic-vacuum-polarization contribution to the muon \(g-2\). In the primary window \[ 0.600 < \sqrt{s} < 0.880\ {\rm GeV}, \] the integrated \(a_\mu\) direction and the bin-by-bin line shape are not the same observable. The scalar direction is only a moderate full-covariance pull, \[ z_{a_\mu}=-1.9753069836215, \] while the identity-camera line-shape sector remains severely stressed: \[ \chi^2_{\rm sh}(I)=58495.38442559397,\qquad \nu_{\rm sh}=139. \] The finite scalar-protected ISR camera search did not close this stress. The best abstract seven-rail branch left \[ \mathbf m_\star=(2,0,-2,0,0,0,-2),\qquad \chi^2_{\rm sh}=37230.3100880383,\qquad \chi^2_{\rm sh}/139=267.8439574679014. \] No-go note. The abstract ISR-camera branch is not a green BaBar line-shape solution. The paper therefore moves to the next lawful object: an active, typed, hashable physical ISR camera packet, with a QED muon-control row that must pass before the pion row is allowed to judge the frozen QTT source. The physical BaBar row is treated as an instrument/access map, not as a retuning of the source: \[ R_{2\pi}^{\rm lab/BaBar} = P_{\rm bin}\,U_{\rm unfold}\,A_{\rm acc}\,R_{\rm ISR}\,F_{\rm FSR}\,V_{\rm VP} \!\left[R_{2\pi}^{\rm src,QTT}\right] +b_{\rm BaBar}. \] The active-packet gate is multiplicative: \[ Q_{\rm active}^{48} = Q_{\rm manifest}Q_{\rm payload}Q_{\rm schema}Q_{\rm units}Q_{\rm bin} Q_{\rm cov}Q_{\rm physops}Q_{\mu{\rm QED}}Q_{\rm sourcehash} Q_{\rm firewall}Q_{\rm scalarshape}Q_{\rm eigen}. \] The muon-control-first rule is the central V48 gate: \[ Q_{\rm active}^{48}=1,\qquad Q_{\mu{\rm ctrl}}=1 \quad\Longrightarrow\quad Q_{\pi{\rm verdict}}\ {\rm may\ open}. \] Equivalently, \[ Q_{\rm active}^{48}=0\ {\rm or}\ Q_{\mu{\rm ctrl}}=0 \quad\Longrightarrow\quad Q_{\pi{\rm verdict}}=0. \] The muon-control statistic is \[ \chi^2_{\mu{\rm ctrl}} = \left(\mathbf y_\mu-\boldsymbol\mu_\mu^{\rm phys}\right)^\top \left(\Sigma_\mu^{\rm full}\right)^+ \left(\mathbf y_\mu-\boldsymbol\mu_\mu^{\rm phys}\right), \qquad p_{\mu{\rm ctrl}}\ge 0.05. \] The release also adds a pion/muon ratio-camera witness: \[ \mathbf r_{\pi/\mu} = \log\!\left(\frac{\mathbf y_\pi-\mathbf b_\pi}{\mathbf y_\mu-\mathbf b_\mu}\right) - \log\!\left( \frac{M_\pi^{\rm phys}\mathbf r_\pi^{\rm src,QTT}} {M_\mu^{\rm phys}\mathbf r_\mu^{\rm QED}} \right), \qquad \chi^2_{\pi/\mu} = \mathbf r_{\pi/\mu}^\top\Sigma_{\pi/\mu}^{+}\mathbf r_{\pi/\mu}. \] The source remains frozen throughout the access-camera judgment: \[ \frac{\partial R_{2\pi}^{\rm src,QTT}} {\partial\left(M_{\rm BaBar}^{\rm phys},\mathbf y_\pi,\mathbf y_\mu, \Sigma_\pi,\Sigma_\mu,\Sigma_{\pi\mu}\right)} =0. \] Status: the active-packet builder theorem, physical ISR camera form, muon-control gate, pion/muon ratio-witness form, scalar/shape split, eigenmode receipt, and no-source-retune firewall are closed. The active BaBar numerical packet remains yellow until the physical pion and muon payloads, covariances, cross-covariance, and hashes are populated: \[ Q_{\rm active}^{48}=0,\qquad Q_{\mu{\rm ctrl}\,{\rm numeric}}^{48}=0,\qquad Q_{\rm source\ retune}^{48}=0. \] Anchors.
