A fossil server folds artifacts older than its ~100-entry unclustered window into clusters and stops announcing those members with igot -- the M cards are the announcement. The client stored a received cluster as ordinary content and read nothing from it, so a pull past that window fetched only the cluster and then terminated, silently, having gained nothing. Cluster membership now folds into the phantom set, so the next round gimmes the members. A pull that reaches a clean terminal still lacking artifacts the peer announced now exits nonzero, rather than reporting a success that leaves a repository quietly out of date. check-in: 8d3ebc0c9d user: dmestas tags: trunk
