Event subscribers got a way to ask "tell me when this module is reachable" without blocking and without giving up on the first no. Callers had no such thing, so a caller facing the same startup race had only two bad options: fail fast, which strands a UI that will never retry, or call straight through and sit in the transport's acquire timeout on whatever thread it was called from — the GUI thread, in practice. whenObjectAvailable() reuses the pending-subscription registry that already exists, as a readiness-only entry: it attaches no subscription, fires its callback exactly once, and is then forgotten rather than being re-armed on reconnect, because a one-shot readiness answer that arrives twice is not an answer. It shares the registry's timer, backoff and diagnostics, so it costs nothing new on qt_remote and shows up in pendingSubscriptions() as "<object>::(readiness)" while it waits. Its first consumer is LogosQmlBridge::callModuleAsync, which can now hold a call issued before its module exists and dispatch it when the module appears.
