Summary

On Arbitrum Sepolia, automatic payouts were sometimes skipped. Right after a Credited event, claimIfOwed read claimable(recipient) from a load-balanced QuickNode node that hadn't reached the crediting block yet. It got 0, returned without logging anything, and the money sat in claimable until someone pressed "Send payout again".

// handleLogs: remember the newest block that credited each recipient
toClaim: Map<Address, creditedAtBlock>

// claimIfOwed(chainId, recipient, creditedAt), up to 4 attempts with 1s/2s/3s backoff:
if (getBlockNumber({ cacheTime: 0 }) < creditedAt) retry
if (claimable(recipient) == 0) retry
submit("claimFor") — retry on a NothingToClaim simulation revert, otherwise log and stop
// gave up -> console.error (used to return silently)

• RawLog has an optional blockNumber. Receipt logs already include it, and extractLogs now parses it from QuickNode payloads (hex or number). If it's missing, the block check is skipped and the zero-retry still applies.
• Claims still run one after another, so the relayer nonce handling is unchanged.
• No contract change. A recipient who was already paid costs about 6 s of retries before giving up.

Verification

• typecheck, lint, unit tests (new extractLogs blockNumber case) and next build pass.
• Live on Arbitrum Sepolia, with a local server on this branch and the production Arbitrum QuickNode webhook paused so the old deployed code couldn't handle the same events: 3 of 3 runs of scripts/relay-smoke.mjs passed, with every deposit and release payout claimed automatically. The webhook was reactivated afterwards. In an earlier run, with the webhook still active, the production deployment (old code) handled one release Credited event first and skipped it the same way. That will stop once this is deployed.
