//! Coverage for the CLI 2.1.286 stream-json drift.
//!
//! 2.1.285 → 2.1.286 added `server_received_wall_ms` on `user` frames and
//! `first_request_input_tokens` plus `user_message_server_received_wall_ms`
//! on `result`.
//!
//! Each frame below carries the new fields and is asserted **fully wrapped** —
//! the typed model captures every wire field with nothing left in an untyped
//! escape hatch.
