// Subscribe/unsubscribe intermittently showed "Failed to update your
// subscriptions" but worked after a refresh — because the kind-30000 list event
// was SENT and persisted, but no relay ACKed it within the 10s window, so
// assertAnyRelayAccepted threw and the optimistic UI was reverted with a scary
// error. Fix: an all-timeout (unconfirmed) publish of the idempotent replaceable
// list is treated as a SOFT SUCCESS (reconciles on next load); only an explicit
// relay rejection (or a pre-publish signer/encryption error) fails loudly. This
// covers the classifier that makes that call.
