# Igneum devnet node, Windows launcher: the node only. Started by START-NODE.bat, which sets the settings as environment
# variables (MAC_NODE, RPC_LISTEN, P2P_LISTEN, APPDIR, UNSYNCED_MINING, EXTRA_ARGS, PLAIN). 3 October 2026.
# The functions live in igneum-common.ps1; START-IGNEUM.bat runs the same code with the miners in the same window.
#
# Starts igneumd.exe --devnet with --appdir, --rpclisten, --listen, one --addpeer per PEER_NODES entry (the seed node and
# the Mac), --nodnsseed, --disable-upnp, --yes and
# --nologfiles (the node's output goes to node-<stamp>.log, a new segment per start). The window shows the NODE card
# (a reading every 5 s while syncing, then every 30 s), a status line goes to the launcher log every 30 s, the logs are
# uploaded every 60 s, a crash restarts the node after 5 to 60 s, Ctrl+C stops it.
#
# Why --addpeer and not --connect: in igneumd (kaspad/src/daemon.rs) --connect sets the inbound limit to 0 and skips
# outbound peers, so the Mac could never dial this PC. --addpeer keeps the Mac as a permanent peer (retried with a
# backoff of up to 8 minutes, components/connectionmanager/src/lib.rs) and leaves the listener open for the Mac.
