A bounded LoopProcessLogData (stopTsNs set) on a buffer that never took a write since process start fell into the ResumeFromDiskError branch, which never checks stopTsNs when ReadFromDiskFn is nil and HasData() is false. The read parked on the notification loop forever while the subscription's idle heartbeats kept the stream looking alive, so a bounded SubscribeMetadata pass on a freshly restarted idle filer never completed. Terminate like the caught-up path does, returning a nil error: leaking the pending ResumeFromDiskError would latch the filer's outer loop into its gap machinery, which parks the bounded subscriber all over again.
