pub fn lookup(tx_hash: B256) -> Option<u64>Expand description
Lookup the recorded L2 gas-used for a tx hash. Some(g) means the tx
must be force-reverted with g total L2 gas (excludes poster gas).
Both entries stem from the same Sepolia ARM-vs-x86 Stylus determinism incident at block ~204,060,000: a contract activated at v40 with the default MaxStackDepth recurses deeply enough that Cranelift’s stack frames consume Rust call stack differently on ARM vs x86, so the two architectures terminate at different ink levels and report different gas. arbreth runs on arm64, so this override is required for replay parity.
