Module caching 

Read-cache propagation helpers

Client-side helpers that guide how cached post bundles spread across the DHT. One piece remembers how far caching has propagated so future walks skip already-cached peers; the other forwards freshly-written bundles to other servers in the background under tokens returned by the write.
