Substrate binds JSON-RPC to loopback and makes opening it deliberately awkward, which is correct for a validator. rpc_expose in the node matrix takes the complete flag string; empty keeps it on loopback. --rpc-methods safe is the load-bearing flag. It permits every state read and author_submitExtrinsic (signed, so no key exposure) while blocking author_rotateKeys, system_addReservedPeer and the rest. --rpc-methods auto happens to downgrade once listening externally, but relying on that makes the safety depend on a flag nobody wrote down. The firewalld rich rule is scoped to the node's own /16, derived from its own resolved address at deploy time -- so no subnet literal enters this repo and the rule follows the host between sites. Loopback is whitelisted from rate limiting because the arena exporter runs beside the node and makes ~4 calls every 2s, which is 120/min -- enough to throttle itself against a naive limit. validate now asserts the bind matches intent in both directions: nothing listening while rpc_expose is set is a failure, and loopback-only is reported as configuration rather than silence.
