Adversarial robustness and conformance tests of the execution layer against a throwaway 3-node simnet on ports 27600+. Six scenarios, each a runnable command with a design-derived pass criterion and a measured result: malformed/boundary txs, nonce games across parallel blocks, RPC fuzz, pgas exhaustion, reorgs under execution, and developer-registry abuse. 98 checks, 0 failures, 0 node panics. Two findings filed in the bench-log entry: the mempool admits txs with gas_limit above B_e (low), and an over-pgas-budget tx is executed natively in full before being skipped for no fee (medium, griefing).
