Hence my question. When it does "repack -a", it at least scans the whole history so you would be sure that all the commits and trees are readable for the purpose of enumerating the objects referred by them (and a bit flip in them will likely be noticed by zlib inflation). But a "gc" does not necessarily run "repack -a" when it does not see too many pack files, so it can end up scanning only the surface of the history to collect the recently created loose objects into a pack, and stop its traversal without going into existing packfiles.
