Worklist passes that transform every function (the class-construction dispatch rewriting dyn.classBasePrototype) rebuild statement objects, so a recorded lazy bag store could be a detached copy. When the class gained prototype data later, only the copy was upgraded and the live store kept creating a bare {} bag: inherited methods read as undefined through the property bag (hono's SmartRouter.match once zod was in the program). Upgrades now also reach the stores as they stand in the generated bodies.
