Convert a measurement without losing declared uncertainty
Convert a measurement without losing declared uncertainty: one decimal value and standard uncertainty across supported length, mass, time or temperature units using exact rational scale/offset arithmetic. No unit guessing, physical validation or expanded uncertainty. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.
