dgb: stand up embedded coin-daemon P2P producer in run-loop (Phase B) - #256
Merged
Conversation
Construct dgb::coin::p2p::NodeP2P<dgb::Config> against the coin_iface ingest seam landed in #250 and dial the local digibyted. On --run with --coin-daemon HOST:PORT (+ --coin-magic / --coin-genesis), the producer speaks the DigiByte Core wire protocol (Scrypt-only consumer), completes the version/verack handshake, drives an initial getheaders from the genesis locator, and fires coin_iface.new_headers / new_tx on each live relay. The wire_*_ingest connectors route those onto HeaderChain::validate_and_append and Mempool::add_tx, so a live feed now flows end-to-end the moment the handshake completes. Coin-daemon wire MAGIC is kept distinct from the sharechain PREFIX isolation primitive; both endpoint and magic are supplied by main() so the binary targets mainnet or a dev regtest daemon without hard-coding. No behavior change when --coin-daemon is absent (coin_p2p stays null).

src/c2pool/main_dgb.cppONLY — the DGB-specific binary entry. Does NOT touch shared run_node, bitcoin_family/, or src/core/. Outsidesrc/impl/dgb/(it is the dgb binary main), so flagged for operator tap per integrator — live consensus-relevant ingest is not auto-merge.Live regtest chain-advance evidence (against reachable digibyted /DigiByte:8.26.2/, proto 70019)
HOLD merge — operator tap.
