Heuristic Solidity linter for a snippet or file (up to 60000 characters): unchecked low-level call/send/delegatecall, value-sending external calls before a storage write (possible reentrancy), arithmetic under pragma below 0.8.0 (overflow risk), and public or external state-changing functions without a visible owner or sender check, with line numbers. Not an audit; misses most real bugs.

x402: an unpaid request gets a 402 with the price and pay-to wallet. The check never pays.
