331-331:⚠️ Potential issue | 🔴 Critical
hostis undefined at this line —NameErrorwill crash the node on startup.The
run_nodefunction useshoston line 331, but this variable is not defined in the function's scope. The function signature is:async def run_node(port: int, connect_to: str | None, fund: int, datadir: str | None):The
--hostargument fromargparse(line 362) is never passed torun_node. Althoughhostis assigned later in the function whenconnect_tois provided (fromconnect_to.rsplit(":", 1)), this occurs after line 331 and only when the--connectflag is used. This will cause aNameErrorin all cases, including the default startup path.🐛 Proposed fix
Update the function signature and call site:
-async def run_node(port: int, connect_to: str | None, fund: int, datadir: str | None): +async def run_node(port: int, host: str, connect_to: str | None, fund: int, datadir: str | None):And in
main():- asyncio.run(run_node(args.port, args.connect, args.fund, args.datadir)) + asyncio.run(run_node(args.port, args.host, args.connect, args.fund, args.datadir))🤖 Prompt for AI Agents
Verify each finding against the current code and only fix it if needed. In `@main.py` at line 331, The bug is that run_node uses an undefined host variable at the call to network.start(port=port, host=host); update run_node to accept a host parameter (e.g., async def run_node(port: int, connect_to: str | None, fund: int, datadir: str | None, host: str | None)) and use that parameter when calling network.start, and then pass the parsed --host value from main() into run_node where it is invoked; ensure the host parameter type/nullable default matches existing usage and update any other call sites of run_node accordingly.

Addressed Issues:
This PR reduces duplicated logic so core rules live in one place, making the code easier to reason about and less likely to drift over time.
It is intentionally minimal and non-breaking.
