Three MediaBrowser pagination loops re-implemented drainPages; it gains an onPage hook (fires after intermediate pages only) so the two progressive-render loops fit as well as the episode queue. Five handwritten FIFO future tails (companion lifecycle, Seerr persistence, tracker write lock, companion host-auth commit, Watch Together message routing) become SerialFutureQueue, and the companion peer service's disconnect/dispose in-flight joins become FutureCoalescer.
