The generic dual cache takes read, write, and remote-failure policies, runs its async operations through the async L2 methods, and provides L2-first counters and atomic affinity claims. Errors propagate by default, and `RemoteFailurePolicy::UseLocal` opts key-value operations and claims into the local tier when L2 is unavailable. Claims compare decoded values, so a pin written by Python still matches. Public Router integration remains follow-up work. Reservations and pubsub still need explicit capabilities owned by their consuming features.
