Artian Source-Only SI Endpoint Bridge Theorem

Reading the Planck-scale endpoint into SI units without a hidden physics row Version: 3.1 Concept DOI: 10.5281/zenodo.20936013 Author: Ali Attar Website: quantumtraction.org \[ \boxed{ \mathfrak B_{\rm SI}^{A5X/A6/A7}: (\ell_A,\hbar,c)\longmapsto \left(\tilde t_A=\frac{\ell_A}{c},\; E_\ast=\frac{\hbar c}{\ell_A}\right). } \] The bridge separates a source endpoint map from any empirical attempt to assign its absolute SI scale. It does not use a hidden Newton, atomic, or electroweak row to define the source object. The finite event whose four-density face appears in the bridge is now pinned explicitly: \[ \boxed{ V_{\rm pix}=\frac{\pi}{6}\ell_A^3, \qquad |\mathcal O_3^+|=24, \qquad \Delta V_A^{(4)}=4\pi\ell_A^4. } \] The release preserves the source-only SI boundary: it makes no claim that a pure-number constructor has already supplied a laboratory metre or joule. The fourth-face owner theorem closes provenance of the finite packet without adding an observational fit.
