Data & measurement
Continuity metrics emphasize intergenerational transmission, corpus completeness, and structural stability. Keep cohort definitions fixed across measurement waves. Symbols: L_sov (Linguistic sovereignty (0 to 1)); W_trans (Count of borrowed/loanwords in active use); W_native (Count of native Kifuliiru words in active use). Log instrument versions, sample frames, and cleaning rules whenever estimates are refreshed so longitudinal comparisons stay valid.
Solution & proof
Conceptual summary: The degree to which Kifuliiru maintains its own vocabulary versus borrowing from French, Swahili, English, or other languages. Treat this as a measurement recipe: map each symbol to an empirical quantity, substitute estimates, and simplify with ordinary algebra (including logarithms, min/max caps, or piecewise branches where shown). Where limits or integrals appear, approximate with discrete sums on cohorts or time steps when closed forms are impractical. Interpret the result against thresholds in the cited source and report uncertainty on inputs.
