… races Public load-balanced RPCs (e.g. publicnode.com) can serve eth_blockNumber and eth_getLogs from backends 1-2 blocks out of sync, producing recurring "block range extends beyond current head block" warnings. Subtracting HEAD_LAG_BLOCKS from the queried head avoids the race; trades ~60s of attestation latency on Ethereum for clean logs. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
