Interpretive note: reading the cap in a 3+3 space-time framework

This document is the interpretive note that accompanies, without contaminating , the pre-recording of binary predictions for Gaia DR4 (separate submission, same date ; DOI: 10.5281/zenodo.24146763). The protocol is phenomenological: its validity does not depend on anything that follows. The note is submitted to timestamp the theoretical reading BEFORE the release of Gaia DR4, so that the priority of the interpretation is established in the same way as that of the predictions. It claims the status of a framework under construction, with its debts declared, not an established theory.
