OutputWaitResult.evidence

One accepted output observation. text is a bounded UTF-8 tail; dropped_bytes counts complete decoded bytes omitted from this result and pending_bytes counts an incomplete UTF-8 suffix retained by the decoder. received_bytes counts raw bytes consumed by this wait. Tail truncation is local retention policy; an actual stream gap instead raises ObservationLost , and a pane or server that ended raises OutputWaitEnded with the text so far. The cursor covers the whole last consumed event, including omitted bytes; it cannot resume within a matched event.
