dig-pex 0.2.0
Peer Exchange (PEX) for the DIG Node peer network — delta-based first-hand known-peer exchange over already-authenticated links (node<->node dig-nat mux, relay->node RLY-008 WebSocket), in the spirit of BitTorrent PEX: periodic added/dropped deltas, hard per-message caps, receiver-enforced minimum interval anti-flood floor, and no third-party re-flooding. Ships a transport-agnostic sans-IO PexEngine embedded by dig-node and dig-relay.
