/// - Otherwise (if `enable_back_to_source` is `false`), dfdaemon will report a download failure.
///
/// **Important Considerations Regarding Timeout Triggers**:
/// This timeout isn't solely for the scheduler's direct response. It can also be triggered
/// if the overall duration of the client's interaction with the scheduler for a task
/// (e.g., client downloading initial pieces and reporting their status back to the scheduler)
/// exceeds `schedule_timeout`. During such client-side processing and reporting,
/// the scheduler might be awaiting these updates before sending its comprehensive
/// scheduling response, and this entire period is subject to the `schedule_timeout`.
///
/// **Configuration Guidance**:
/// To prevent premature timeouts, `schedule_timeout` should be configured to a value
/// greater than the maximum expected time for the *entire scheduling interaction*.
/// This includes:
/// 1. The scheduler's own processing and response time.
/// 2. The time taken by the client to download any initial pieces and download all pieces finished,
/// as this communication is part of the scheduling phase.
///
/// Setting this value too low can lead to `TokioStreamElapsed` errors even if the
/// network and scheduler are functioning correctly but the combined interaction time
/// is longer than the configured timeout.
