A new Light Frame Infrastructure Series addendum, LFIS-23, has been published on Zenodo.
This volume clarifies how observational tests of Light Frame Cadence Theory (LFCT) are to be interpreted, introducing a formal distinction between constraint-level predictions and observational-level statistical tests. It resolves prior ambiguities in the interpretation of Regime 9 (global drift) and clarifies the current status of Regime 2 (pressure-supported dwarf systems).
LFIS-23 introduces no new physics or data. It defines verification semantics only and serves as a canonical reference for interpreting LFCT verification claims across existing and future observational test suites.
This addendum is intended primarily for reviewers, replicators, and automated analysis tools.
