//! Contract tests for the manual upstream A/V sync harness.
//!
//! Scope: statically guard the workstation-side tunnel/bootstrap behavior.
//! Targets: `scripts/manual/run_upstream_av_sync.sh`.
//! Why: the manual probe should reach Theia through SSH even when the gRPC
//! port is not exposed on the public SSH endpoint.
