simulator-api 0.16.0

//! Pins the `AgentParams` JSON wire contract. The address-shaped fields are
//! typed `Address` behind `DisplayFromStr`, so they must still serialize as
//! base58 strings — clients and the `--agents-json` sidecar arg depend on it.

use simulator_api::AgentParams;

/// Same shape as the reroute/agent e2e fixture.
