Apply the composite trapezoidal rule to 2-128 equally spaced integer samples. Returns an exact rational arithmetic result, declared units and an integrity receipt. No quadrature-error estimate or claim of an exact underlying integral. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.

Check a declared bandwidth and up to 16 tones against the strict Nyquist inequality, with equality reported separately. Computes folded tone frequencies exactly. Assumes uniform sampling, bandlimited input and no jitter; does not verify filters, acquisition hardware or real signal bandwidth.
