//! Exit-code wiring for the `nautilus` binary.

// `analyze-pools` exits non-zero when a pool fails, so batch jobs detect partial failures.
//
// Spawning the built binary is the only way to exercise `main`'s `run() -> ExitCode::FAILURE`
// 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`.
