CometBFT config.toml uses underscore keys; the sed targeted hyphens (rpc-servers etc.) so they never matched -> rpc_servers stayed empty -> 'at least 2 RPC servers required, got 0'. Now section-anchored to [statesync] + [_-] tolerant. (This is also why sei never held chainhead — same hyphen bug in its bespoke init.)
