// mapping. With no RPC URL available, the single pool task fails at URL resolution,
// `run_analyze_pools` counts the failure and bails, and `main` maps that error to a non-zero
// exit. The child runs from a scratch directory with the RPC env vars removed so the failure is
// deterministic regardless of the host environment or a repository `.env`.
