LFIS–23: Verification Semantics Addendum

LFIS–23 is a verification-semantics addendum for Light Frame Cadence Theory. Its purpose is not to introduce new physics, new data, or new derivations, but to clarify how LFCT observational tests are to be interpreted. The volume formalizes a two-level framework in which some LFCT claims are exact constraint-level predictions fixed by theory, while others are observational-level instantiations that test statistical consistency, boundedness, or coherence under finite-data conditions. The volume distinguishes quantitative prediction regimes from descriptive consistency regimes and sets explicit rules for how each class should be evaluated. Quantitative regimes are those in which LFCT specifies a numerical target whose persistent deviation would constitute falsification at the constraint level. Descriptive regimes are those in which LFCT does not yet canonically state a unique numerical target, but still imposes boundedness, stability, and non-divergence as falsifiable requirements. Ambiguous regimes are identified as such rather than promoted by inference. LFIS–23 also resolves two specific interpretive issues in the observational program. It clarifies that Regime 9 (global drift) is a quantitative test with the constraint-level prediction κ = 0, tested statistically under finite-data conditions, and it clarifies that Regime 2 (pressure-supported dwarf spheroidal systems) remains a descriptive consistency regime under current canonical documentation. LFIS–23 therefore serves as the semantic-governance volume of the Light Frame Infrastructure Series, fixing how LFCT observational results are to be classified, interpreted, and evaluated across regimes.
