When joining a network via
pd testnet join
, pd already inspects the peers known to the target bootstrap node, and includes those peers in the generated CometBFT config. Technically it's not correct to assume that these peers are seeds, but limiting to a threshold (#3063) ensures that only a few nodes will be miscategorized this way.The new behavior introduced here is that
pd testnet join
will inspect monikers of peers learned from the bootstrap node, and if the string "seed" appears in the moniker, guarantee that peer lands in theseeds
field of the CometBFT config.To complement this change, we update the deployment logic to create a seed node, and ensure that seed node is excluded from the loadbalanced RPC, to avoid hitting it via the join request (in which case it won't report many peers, because seed nodes drop peer connections after serving address info).
